What are the differences between water based paint and oil based paint? Where do you use paint in ho

What are the differences between water-based paint and oil-based paint? Where do you use paint in home improvement? Oil-based paints have higher relative hardness and fullness, but water-based paints are more environmentally friendly.

After the water-based paint is applied to the wall, the paint surface will be kept fresh and clean for a long time, and it will not be so easy to yellow. Because oil-based paint always emits a large number of harmful gases, it "ages" quickly, is easy to turn yellow, and the freshness does not last long.

1.Oil-based paint is also called grease paint. A coating with dry oil as the main film-forming substance, mainly including clear oil, thick paint, oil-based blending paint, oil-based anti-rust paint, putty, putty, etc.

The oils used are mainly tung oil, flaxseed oil, perilla seed oil, soybean oil, sunflower oil, fish oil, etc. It has the characteristics of easy production, low quality, good brushability, flexible coating film and good permeability. Water-based paints, water-based anti-rust paints, water-based wood paints, wood wax oils.

Using water as a solvent saves 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, which improves the working environment conditions. Generally speaking, the organic solvent of water-based coatings is between 5% and 15%, while the organic solvents of cathode electrophoretic coatings are reduced to the following, which has a significant effect on reducing pollution and saving resources.

2.The thinner of water-based paint is generally made of water, so there is no volatilization of toxic substances, which is relatively environmentally friendly and harmless to human health. Oil-based paints are different.

Its thinners are mostly banana water and tianna water. This substance contains large amounts of toxic substances, such as benzene and xylene, and can even cause cancer. After the water-based paint is applied to the wall, due to its less volatiles, the paint surface can be kept fresh and clean for a long time after painting, and it will not be so easy to yellow.

As for oil-based paint, because it always emits a large number of harmful gases, it "ages" quickly, it is easy to turn yellow, and the freshness does not last long.

3.Paint is paint. The two can sometimes be equated.

Sometimes there is a difference. Coatings have a wider range of applications. Many owners think that water-based paint is latex paint, and latex paint is water-based.

In fact, there are some misunderstandings in this understanding. Oil-based paints have higher relative hardness and fullness, but water-based paints are more environmentally friendly. Usually oil-based paints use organic solvents, often called "tena water" or "banana water", which are polluting and can be burned.

It can be seen that there is an essential difference between water-based paint and oil-based paint in terms of environmental protection and health. Water-based wood paint is a product with high technical difficulty and high technology content in wood coating. Water-based wood paint has the advantages of non-toxic, environmental protection, odorless, less volatiles, high safety, no yellowing, and large coating area.

Oil-based paint, also known as grease paint, is a kind of coating with dry oil as the main film-forming substance, mainly including clear oil, oil-based blending agent, oil-based anti-rust paint and putty, putty, putty, etc., this coating is easy to produce, low-cost, good brushability, flexible coating film, good permeability, water-based paint uses water as a solvent, saves a lot of resources, eliminates the fire hazard during construction, reduces air pollution, and only uses a small amount of low-toxicity alcohol ether organic solvents, which improves the working environment conditions; Paint is used when scraping walls, and both primers and topcoats need to be painted.

The nature is different, the concept is different, the ingredients are different, the taste is different, and the quality is different; Walls, wardrobes, shoe cabinets, wine cabinets, furniture, TV cabinets, and cabinets are all painted.

Water-based paint is non-toxic, odorless, environmentally friendly and safe, and can be moved in after painting, while oil-based paint will volatilize harmful gases in the drying process due to its organic solvents. When decorating a home, it is generally on the cabinet and needs to be sprayed with paint.

Paints are very common in our lives, especially when decorating, and it is often the pungent smell that catches our attention. And there are many types of paints, for water-based paint and oil-based paint may only be heard of for us, but I don't know where the specific difference is. So, next I will introduce to you the difference between water-based paint and oil-based paint.

1. Comparison of the appearance of water-based paint and oil-based paint.

1. Oil-based paint contains a large number of first-class odors, and the smell mold contains harmful substances such as benzene, and it is necessary to remove formaldehyde and other measures for the house, and the harmful gases will be released and volatilized for 10-15 years; easy to turn yellow, poor persistence; The quality of the paint film is good, but it is not easy to repair after being damaged.

2. Water-based paint is non-toxic and tasteless, does not contain harmful chemicals, and can be moved in at any time; There will be no defects such as yellowing, and it will last as new; The paint film is not as hard as paint, but the hardness and scratch resistance of the new generation of PU water-based paint can be comparable to paint, and it can also achieve the effect of "seeing wood but not paint".

2. Comparison of water-based paint and oil-based paint for environmental protection.

1. Oil-based paint products contain benzene, toluene and their derivatives, which are more toxic, and the toxicity of polyester paint is the highest, and the toxicity of nitro paint is secondary; Highly flammable; * Strong sexual odor. 2. Water-based paint is made of water as a dilution solvent, with ultra-low VOC content, non-toxic and tasteless, good environmental performance, and safe and non-flammable characteristics.

3. Comparison of the comprehensive performance of water-based paint and oil-based paint.

1. Ordinary polyurethane paint is added with Yousong machine curing agent, and the hardness of the paint film is the highest; The effect of texture and fullness is also the best.

2. Nitro paint (oil-based paint) has to be painted many times, the hardness of the paint film is the worst, and the feel and fullness are not very good.

3. Water-based wood paint adopts water-based acrylic synthesis system, and the hardness can reach the physical index of 2h; Using the technology of thin coating + "virtual texture", the feel and fullness effect is good.

Fourth, the construction cost comparison of water-based paint and oil-based paint.

1. After the water-based paint is used up, the remaining paint can be stored in a cool place and continued to be used later, and the paint must be used up at one time, otherwise it will only be wasted.

2. Water-based paint repair furniture can be applied directly, and paint needs to be polished first.

3. Water-based paint has no special construction requirements, ordinary people can also paint, paint requires cumbersome steps, it is best to be a professional, and it is difficult for ordinary people to brush well.

Paint, also known as oil-based paint, is a decorative material often used in homes or other buildings. The paint has a very pungent smell, and houses decorated with it are generally ventilated for a long time before they can be inhabited or used. However, with the progress of society, a more environmentally friendly water-based paint has appeared on the market.

So what kind of paint is water-based paint? What is the difference between it and oil-based paint? Let me answer them all for you.

1. What kind of paint is water-based paint?

What kind of paint is water-based paint? Broadly speaking, water-based paint is a resin paint with water as a dispersant, mainly including: water-soluble water-based paint, water-diluted water-based paint and water-dispersible water-based paint.

However, by definition, water-based paint is a paint that uses water as a thinner and does not contain organic solvents.

2. The difference between water-based paint and oil-based paint.

a. Environmental protection index.

Since water-based paint is used as a dispersant, water-based paint does not contain formaldehyde, toluene and other toxic and harmful substances, that is, the VOC content in water-based paint is low, therefore, the environmental protection index of water-based paint is high, not only will not cause pollution to the environment, but also will not cause harm to the human body, is green and safe.

On the contrary, oil-based paint is made of organic solvents such as Xinna water, which is formulated with benzene, acetic acid and ethyl ester, indicating that it contains harmful substances such as toluene, so it does not have the characteristics of environmental protection and will cause harm to human health.

b. Smell. It is said that water-based paint does not contain formaldehyde, toluene and other harmful substances, so it will not produce ** smell in the process of painting silver touch, and it is precisely because of this characteristic that when the water-based paint is painted, Ma Fengfeng can talk about staying in it.

Oily paint is not good, because it is prepared with benzene, acetic acid and other substances, so when painting, toxic gases will volatilize into the air, so it will make people feel pungent; In addition, a house that has been renovated with paint should be moved in at least one to two months apart.

c. Service life.

Water-based paint adopts advanced film-forming technology, the hardness of the paint film is high, the surface layer is hard and firm, the wear resistance is strong, the flexibility is high, and it will not turn white due to collision. In addition, it is safe and non-flammable, and has a long service life.

The hardness of the paint film of oily paint is poor, and it needs to be painted many times to achieve the effect of water-based paint; Moreover, the paint film is easy to turn white after being impacted, has poor wear resistance, is easy to spontaneously combust, is not easy to store, and has a relatively short service life. My conclusion: The above is an introduction to what kind of paint is water-based paint and what is the difference between water-based paint and oil-based paint.

Therefore, for the health of your family, it is recommended that you choose water-based paints with high environmental protection coefficients.
