The difference between water based paint and oil based paint, which one is better?

The raw materials, characteristics, hazards, durability, and complexity of construction are different.

1. Raw materials oil-based paint contains more oil, which can play a good decorative effect and protective role, and the raw material of water-based paint is water-based, non-toxic and harmless, and is an environmentally friendly material. 2. Characteristics of oil-based paint low cost, many varieties, strong permeability, large taste, water-based paint is harmless to the human body, does not pollute the environment, the paint film is plump, wear-resistant, etc. 3. Hazards Oil-based paint has a large number of harmful carcinogens, and water-based paint uses water as a thinner, which is harmless to the human body.

4. Durability Arita Precision Chemical water-based paint will not easily turn yellow. Oil-based paint is easy to turn yellow, and durability is not good. 5. The construction is simple and water-based paint can be painted after simple training, and oil-based paint must be painted after professional training, which is more professional.

Water-based paint is good.

The components of traditional paints include oil, resin, pigments, etc., most of these substances are organic substances, in order to make them mix evenly, organic solvents also need to be added, which may dissolve formaldehyde, benzene and other harmful substances to the human body.

The water-based paint is made of water as a solvent, and the main components such as resin in the paint are modified, so that the original insoluble substances have hydrophilicity, and some important auxiliaries and a small amount of alcohols and ethers with low toxicity will be added to help dissolve, and the smell is very small, which is indeed much more environmentally friendly than traditional paints.

Precautions for the use of water-based paint.

For example, due to the presence of a large amount of water, it may cause certain corrosion to moisture-prone parts such as containers and conveying pipelines.

Water-based paints are polymer dispersion systems, and the dispersion effect of water on pigments is sometimes not as good as that of traditional paints. In addition, due to the high surface tension of water, dirt will cause shrinkage holes in the coating film and affect the appearance, so the requirements for the cleanliness of the surface of the object are higher when using water-based paint.

The above content refers to People's Daily Online - Choose water-based paint for decoration, is it really more environmentally friendly than traditional paint?

1. Environmental performance: water-based paint: diluted with water, there is little harm to the human body. Oil-based paint: diluted with banana water and Tianna water, which contains benzene and xylene substances that can cause cancer.

2. Odor: water-based paint: no odor, no harmful substances, can be moved in immediately. Oil-based paint: The smell is particularly pungent and harmful to the human body. The odor will only be volatilized in 1-2 months after use, but a large number of harmful gases will still be released and volatilized for 10-15 years.

3. Appearance: water-based paint: no harmful substances, no volatile, so it will not turn yellow and last as new.

Oil-based paint: harmful substances are constantly volatile, easy to turn yellow, and the durability is not good. Water-based paint: The new generation of PU water-based paint products is not inferior to the advantages of oil-based paint. It can also make the effect of "seeing the wood but not seeing the paint" unique to high-end furniture that cannot be achieved by oil-based paint.

Oil-based paint: The quality of the paint film is better, but the paint film is harder and brittle, and it is not easy to repair after breakage.

4. Storage: water-based paint: non-flammable, no requirements for storage.

What is the difference between oil-based paint and water-based paint.

There are no special requirements for the construction of water-based paint oil brush, after simple training, it can be painted, and it is extremely convenient for those who need to paint and repair themselves, but oil-based paint must go through professional training and practice before it can be painted.

2. The smell is different.

The smell of water-based paint itself is more environmentally friendly, most of the water-based paint does not contain harmful carcinogens, is not rich in harmful chemicals, non-toxic and tasteless, can be moved in at any time after painting, there will be no shortcomings such as easy yellowing, durable as new.

Oil-based paint is rich in a lot of influencing odors, the smell is rich in benzene and other harmful substances, and it is necessary to remove formaldehyde and other methods for the house, which is easy to turn yellow and has poor durability, but it is not easy to correct after damage.

3. The environmental performance is different.

Water-based paint only needs to use water as a thinner to paint it, which is harmless to human health.

Oil-based paints mostly use chemical agents such as banana water and Tianna water as diluents, which contain a large amount of benzene, xylene and other harmful carcinogens.

4. Different storage methods.

Water-based paint is environmentally friendly and non-flammable, just keep it sealed, there are no special storage requirements, oil-based paint is flammable and insoluble in water when it is not dry, and must be stored separately in accordance with fire protection requirements.

5. The available materials are different.

If it is a metal product, just choose the paint in the case of on-site assembly, and if it is a wood product that needs to be cut and sanded when it is installed on site, then water-based paint can be considered.

It is necessary to decide who has the advantage according to the needs of the individual, and each has its own characteristics and uses.

Some people will mix paint with paint, but there is a difference between the two. The range of paints is wider. There may also be owners who think that water-based paints are latex paints, and latex paints are water-based.

In fact, there are certain misunderstandings. Coating: A general term for a class of liquid or solid materials that can form a solid coating film with protection, decoration or special properties (such as insulation, anti-corrosion, signs, etc.) applied to the surface of an object.

Including oil (sexual) paint, water-based paint, powder coating. Paint: A liquid paint that can be flowed.

Including oil (sex) paint and water-based paint. Paints: oil-based paints that use organic solvents as a medium or high solids and solvent-free.

Water-based paint: A paint that can be dissolved or dispersed with water. (water-based wood paint, latex paint) latex paint:

Latex paint, also known as synthetic resin emulsion coating, is a kind of water-based coating prepared by adding pigments, fillers and various additives to synthetic resin emulsion as the base material.

1. Environmental protection water-based is better than oil-based: From the perspective of environmental protection, water-based paint is better than oil-based paint, which mainly depends on the ingredients they add. The main thinner of oil-based paint is Tianna water, which contains harmful substances such as benzene and xylene, so the smell is large and it takes a longer time to disperse; The water-based paint is made of water as a thinner, and the dispersal time is shorter than that of oil-based paint, and European and American countries stipulate that all wood furniture can only be water-based paint, but there is no such provision in China.

At present, China only has clear provisions on the environmental protection indicators of oil-based paint, and there is no unified industry standard for water-based paint, such as how much is the safety range of additives for water-based paint, and there is no unified statement. Moreover, water-based paint has high requirements for the construction process, and if the operation is not standardized, it will also lead to excessive harmful substances.

2. Water is higher than oil: If you look at the surface of the finished furniture, it is difficult to distinguish whether it is oil-based paint or water-based paint, but it can be judged by smelling. Oil-based paint needs to be dissipated for a long time, otherwise there will be some aromatic smell, and water-based paint will not have a taste.

The dispersal time of water-based lacquer furniture is about 7 days, and it is not more than half a month; It takes two months for oil-based paint to disperse less odor, and it is necessary to open the window frequently for ventilation in the early stage.

As far as the paint is concerned, usually 5kg per group (the set of paint, curing agent and thinner combined is called a group) is about 70 100 yuan higher than oil-based paint, and the construction cost of workers is much higher than that of oil-based paint. Therefore, when choosing paint, you should fully refer to your own economic conditions and check-in time, so as to avoid unnecessary waste.

3. The effect of water-based paint is better than oil-based: water-based paint and oil-based paint are suitable for a wide range of wood species, there is no special limit, and the color of the processed finished product mainly depends on the process. However, the texture of water-based paint is more prominent than that of oil-based paint, the paint film feels better, the firmness of the color is also better, and it is not easy to appear yellowing, bubbles, particles and other common shortcomings of oil-based paint.

According to experts: "The hiding power of oil-based paint is stronger, if the wood is not very good and there are more scars, it is better to paint with oil-based paint." However, with the improvement of water-based paint, water-based paint can also be made in various colors, and the hiding power is comparable to that of oil-based paint. ”

It can be seen that according to the above analysis, water-based paint is more environmentally friendly, so everyone must look at which one is more environmentally friendly when choosing paint in the market!

Comparison of the advantages of water-based paint and oil-based paint.

Water-based paint is environmentally friendly, and oil-based paint has a good effect.

First, the nature is different.

1. Water-based paint properties: a type of paint.

2. Oil-based paint properties: a type of paint with dry oil as the main film-forming substance.

Second, the advantages are different.

1. Advantages of water-based paint:

1) Use water as a solvent to save a lot of resources; Eliminate fire hazards during construction; reducing air pollution; Only a small amount of low-toxicity alcohol ether organic solvent is used to improve the working environment. The organic solvent content of ordinary water-based coatings is between 5% and 15%, and the organic solvent content of cathode electrophoretic coatings is reduced to below, which is of great significance for reducing pollution and saving resources.

2) Water-based coatings can be directly applied to wet surfaces and humid environments, with good adaptability to the surface of materials and strong adhesion of coatings.

3) Painting tools can be cleaned with water, which greatly reduces the consumption of cleaning solvent and effectively reduces the damage to construction personnel.

4) The electrophoretic coating film is uniform and flat. Good flattening; The inner cavity, weld, edges and edges can be coated with a certain thickness of coating film, which has good protection; The electrophoretic coating has the best corrosion resistance, and the salt spray resistance of the thick film cathode electrophoretic coating can reach up to 1200h.

2. Advantages of oil-based paint:

1) Protection function.

Anti-corrosion, waterproof, oil-proof, chemical-resistant, light-resistant, temperature-resistant, etc. Items are exposed to the atmosphere and corroded by oxygen and water, causing damage such as metal corrosion, wood decay, and cement weathering. Applying an oil-based coating to the surface of an object to form a protective film can prevent or delay the occurrence and development of these damage phenomena and prolong the service life of various materials.

Therefore, the protective effect is one of the main functions of oil-based coatings.

2) Decorative function.

Color, gloss, pattern, flatness, etc. Painted with oil-based paint, objects of different materials can get a colorful appearance, play a role in beautifying the human living environment, and make a non-negligible contribution to the material and spiritual life of human beings.

3) Other features.

Marking, anti-fouling, insulation, etc. This function is playing an increasingly important role in modern paints. Some modern oil-based coatings offer a variety of special features, such as:

Electrical insulation, electrical conduction, shielding electromagnetic waves, anti-static generation and other functions; Anti-mildew, sterilization, insecticide, anti-adhesion of marine organisms and other biochemical functions.

1. Characteristics of oil-based paint.

Oil-based paint is also known as paint and grease paint. A type of paint with oleoresin as the main film-forming substance, mainly including alkyd paint, epoxy paint, polyurethane paint, acrylic paint, fluorocarbon paint, chlorinated rubber paint, amino paint, nitro paint, etc.

The oils used are mainly tung oil, linseed oil, catalpa oil, soybean oil, sunflower oil, fish oil, etc., which are characterized by easy production, low cost, good brushability, flexible coating film and good permeability.

2. Characteristics of water-based paint.

Any paint that uses water as a solvent or as a dispersion medium can be called water-based paint. There are three types of water-based paints: water-soluble paints, water-diluble paints, and water-dispersible paints (latex paints).

Water-soluble paint is made of water-soluble resin as a film-forming substance, represented by polyvinyl alcohol and its various modifiers, in addition to water-soluble alkyd resin, water-soluble epoxy resin, water-soluble acrylic resin, water-soluble fluorine resin and inorganic polymer water-based resin.

3. Which is better.

In terms of procurement cost, of course, the cost of oil-based paint is low; But from the point of view of safety and performance, water-based paint is superior. If the floor is too slippery, athletes are more likely to fall or use more energy during exercise, which is not conducive to sports. Water-based paint for sports wood flooring is an important part of the structure of wood flooring, because it determines the slip coefficient (sliding friction coefficient) of sports wood flooring.

What is the difference between oil-based paint and water-based paint.

Summary. Water-based and oil-based coatings have their advantages. Saying that water-based coatings are good is not "blindly pursuing water-based omnipotence".

Like other coatings, water-based paints can be good or bad, and quality can be high or low. Therefore, we should continue to work on improving quality. But if everyone is not aware of the use of water-based paints, even if it is ***, it will not be able to be "environmentally friendly", because if it is not used on a large scale, the impact is limited.

After all, large-scale projects have limited funds, water-based coatings are more expensive, oil-based coatings for projects are cheaper, and oil-based coatings for mechanical coatings are more suitable.

First of all, it is undeniable that water-based coatings do have their advantages, but we cannot blindly pursue water-based. After using it, you know that it is not perfect. For different construction requirements, some water-based coatings cannot be met.

In some ways, water-based paints can't replace oil-based paints, at least for now.

Water-based and oil-based coatings have their advantages. Saying that water-based coatings are good is not "blindly pursuing water-based omnipotence". Like other coatings, water-based paints can be good or bad, and quality can be high or low.

Therefore, we should continue to work on improving quality.

After all, large-scale projects have limited funds, water-based coatings are more expensive, oil-based coatings for projects are cheaper, and oil-based coatings for mechanical coatings are more suitable.

After construction, is it better to paint or water-based paint, who has a longer time, and is not easy to discolor.

Hydrophilic paint has a long time and is not easy to fade.

Where the sun is often basked, is it better to have rain or water-based paint, and can water-based paint be used on metal to prevent rust.

Can I paint water-based paint now?

It is not recommended to brush water-based paint that has been painted.

But the paint has changed color.

You can remove the paint, in the brush water-based paint.

It's not good to go on the wooden door.

Try it with alcohol.

Can water-based paint be applied to metal?

Yes pro.
