What are the differences between water based paint and wood paint, and what are the advantages and d

What are the general properties of wood paint?

The properties of wood coatings can be divided into:

Durability: brushing, spraying performance, whether there are brush marks, and wet film anti-sagging, etc.

Coating appearance: such as gloss, fullness, color.

Adhesion: Adhesion to the substrate or to the old paint film.

Hiding power: After the normal number of brushing times, whether the bottom is covered (referring to the solid color paint).

Resistance: chemical resistance, abrasion resistance, yellowing resistance, etc.

Storage stability: whether it is precipitated, viscosity stability, etc.

5. The composition of wood paint.

Wood paint is composed of film-forming substances, pigments and fillers, and additives.

Film-forming substance function: define the type of paint and provide film-forming; adhesive pigments and fillers; Provides anti-gas.

Weather and other chemical resistance.

Pigment and filler function: provide color; increase the solids content; reduce costs; Provides filling.

Adjuvant effect: helps in the production, storage and construction of paints.

The function of the solvent: dissolves the resin, is easy to apply; Provide good liquidity; Control and adjustment.

Section drying time.

What are the types of wood paint? What are the characteristics of each?

Wood paint can generally be divided into oil-based wood paint and water-based wood paint; According to its chemical composition, it can be divided into nitro paint, polyurethane, polyester, alkyd paint, water-based paint and other categories; It can also be divided into three categories: putty, primer and topcoat according to the level of use.

Here are a few of the properties of lacquer:

The construction of nitro paint is simple, but the solid content is low, the number of applications is more, the paint film is not full, and the hardness is not as good as PU paint.

Poor resistance to scalding, poor resistance to yellowing;

Alkyd paint is simple to construct and has low odor, but it dries slowly and has low hardness;

PU paint has high hardness, high fullness, good chemical resistance and excellent comprehensive performance, but the construction is relatively demanding.

High; Water-based wood paint has excellent environmental performance, but it is not recommended that the hardness of the paint film is not as good as that of PU polyester paint.

construction on the ground, often scraping stressed areas.

Home decoration will often use water-based wood paint, so what are the advantages and disadvantages of water-based wood paint? Come and check it out.

First, the advantages of water-based wood paint.

1. High environmental protection. Water-based wood paint uses water as a thinner, which is non-toxic and tasteless; It does not contain harmful solvents such as benzene and does not contain free TDI. Oil-based wood paints are made from banana water or tina water as a diluent, which contains a lot of benzene toxic evaporating substances, which evaporate for up to 10-15 years.

If you live in it for a long time, it will cause harm to the nervous system and hematopoietic arrangements, causing the number of white blood cells and platelets in the blood to decrease, and you will suffer from leukemia.

2. It is not easy to incinerate. Water-based wood paint uses water as a thinner and is not classified as a flammable product, while oil-based wood paint contains a lot of organic matter and solvent gasoline, which is classified as a high-risk flammable product, so you should be extra careful when storing.

3. Convenient construction. It can be brushed and sprayed, and it is not easy to show common defects such as bubbles and particles in oil-based paint, and the paint film feels good. The solid content is still higher in Liangzhou, which is appropriate with nitro paint, and can also make a full paint film.

Second, the advantages of water-based wood paint.

1. Low paint hardness. One of the major defects of water-based laughing slag tung wood paint is that the hardness of the paint is not high enough, which leads to easy wear and scratches.

2. The construction temperature should not be too high. Under high temperature conditions, water-based wood paint can not be thickly coated for construction, otherwise the surface of the paint film dries quickly to form a film while the thick inner layer dries slowly, and the flow of paint produces poor tension during the drying process, and the surface of the film is easy to be uneven and wrinkled, and it is easy to cause primer cracking.

3. Poor adhesion. After the application of water-based wood paint in moderately high air, it will be found that the bond between the coating layers is not firm, resulting in poor adhesion, and the layers will peel off each other, and even tear off the whole piece like tearing skin.

4. The paint layer is easy to whitish. Water-based wood paints applied in wet weather will cause the paint layer to turn white.

5. Expensive. Compared with other paints, the ** of water-based wood paint under the same conditions is slightly higher.

6. It is easy to pollute water quality. Water-based wood paint is easy to pollute water quality during construction and production.

After the above introduction, we all know what are the advantages and disadvantages of water-based wood paint, right? When you buy water-based wood paint, you must choose a big brand with quality assurance, and don't blindly follow the trend, so as not to buy inferior products.

Summary. 1. Advantages and disadvantages of water-based wood paint - rust prevention and high temperature resistance.

2. Advantages and disadvantages of water-based wood paint - water-soluble coating, non-toxic and environmentally friendly, free of harmful solvents such as benzene, and free TDI.

3. Advantages and disadvantages of water-based wood paint - it can be constructed at the same time with other paints such as latex paint 4. Advantages and disadvantages of water-based wood paint - no yellowing, excellent water resistance, and no combustion.

5. Advantages and disadvantages of water-based wood paint - high solid content, plump and tough paint film.

1. Classification and characteristics of water-based wood paint.

Water-based wood paint is a lacquer that uses water as a thinner. Water-based wood paint can generally be divided into three categories, one is acrylic as the main component of water-based wood paint, its main feature is good adhesion, will not deepen the color of wood, but poor wear resistance and chemical resistance. Because of its low technical content and low cost, it has become the main product on the market at present.

The second type is water-based wood paint with acrylic and polyurethane synthesis as the main component, which is characterized by acrylic paint in addition to the characteristics of acrylic paint, but also adds the wear resistance and chemical resistance of polyurethane. The third category is 100% polyurethane water-based paint, whose wear resistance is even several times that of oil-based paint, which is a high-end product in water-based paint, but the technology is only mastered by a few professional companies. Understand the classification of water-based wood paint, consumers can choose according to their own needs, such as the need to paint doors, windows, furniture and other places with low requirements for wear resistance, as long as you choose the first or second type of water-based paint; If you want to paint wooden floors, it is best to use a third-class water-based paint.

Although the types are clear, it is not easy to distinguish the water-based wood paint on the market. Because the names and composition labels of water-based wood paints are not uniform among manufacturers, it is easy for consumers to be confused. For example, water-based wood paint with acrylic as the main component has two standard methods: acrylic and acrylate.

What's more, water-based paints with acrylic and polyurethane compounds as the main components are labeled as water-based polyester paints. Consumers are best able to judge by sight and nose: acrylic is a milky liquid like milk, with a slightly sour taste.

Polyurethane is a translucent liquid like egg white, with a faint greasy scent. Of course, the best way is to buy products produced by professional water-based wood paint manufacturers.

2. Advantages and disadvantages of water-based wood paint.

A. Water-soluble coating, non-toxic and environmentally friendly, no harmful solvents such as benzene, no free TDI. b. The construction is simple and convenient, and it is not easy to have common problems such as bubbles and particles, and the paint film feels good.

c. High solid content, plump and tough paint film.

d. No yellowing, excellent water resistance, no combustion.

e. Anti-rust and high-temperature resistant.

f. It can be constructed at the same time as other paints such as latex paint.

g. The hardness of some water-based paints is not high, and it is easy to scratch, which should be paid special attention to when choosing.

In general, water-based paint is a good choice in terms of construction and environmental protection, except for the slightly higher **.

Water-based wood paint is a kind of paint with water, which is incompatible with water and oil, but water-based wood paint is an exception, so it will also have more advantages than other paints. Of course, it is not only advantages, but also disadvantages, the following number of home network I will give you a detailed introduction to the advantages and disadvantages of water-based wood paint.
