What types of interior wall paints are currently available for interior decoration?

One type is low-grade water-soluble paint, which is made by dissolving polyvinyl alcohol in water and adding pigments and other additives. . In order to improve its performance and reduce costs, various methods have been adopted, and there are many brands. The main products are 106 and 107803 interior wall coatings. The disadvantage of this kind of coating is that it is not resistant to water and alkali, and the coating is easy to peel off after getting wet. It is a low-grade interior wall coating and is suitable for general interior wall decoration. This type of coating has the advantages of being cheap, non-toxic, odorless, and easy to construct. The powder cannot be removed by dry wiping. Because the film-forming substance is water-soluble, some traces will always be left after scrubbing with a wet cloth. The durability is not good and it is easy to yellow and discolor. However, it is cheap and is very convenient to construct. At present, Consumption is still the largest, accounting for about 50% of the market, and is mostly used for interior wall decoration in mid- to low-end homes or temporary homes.

The second type is latex paint, which uses water as the medium and uses aqueous solutions of acrylates, styrene-acrylate polymers, and vinyl acetate polymers as film-forming Substance, made by adding a variety of auxiliary ingredients. Its film-forming substance is insoluble in water. The water resistance and weather resistance of the coating film are greatly improved compared with the first type. It leaves no trace after wet scrubbing and has different decorations such as flat gloss and high gloss. type. Since it currently has fewer colors, the decorative effect is similar to that of category 106. In fact, these two types of coatings are not of the same grade at all. They are mid-to-high-end coatings. Although they are more expensive, they occupy an increasing market share due to their excellent performance and decorative effects. A good latex paint layer has good water resistance, alkali resistance, and wash resistance. The coating will never peel off when it gets wet. Generally speaking (under the same pigment, volume, and concentration conditions), styrene-acrylic latex paint is more resistant to water, alkali, and scrubbing than ethylene-propylene latex paint, and ethylene-propylene latex paint is better than polyvinyl acetate latex paint (commonly known as latex paint). good.

The third category is the currently very popular colorful paint. The film-forming substance of this paint is nitrocellulose, which is dispersed in the water phase in the form of oil-in-water. Multiple color patterns can be formed in one spray.

The fourth category is imitation porcelain paint. Its decorative effect is delicate, smooth and elegant, and the price is not high. However, the construction process is complicated and the wet rub resistance is poor

What should be paid attention to when constructing the paint:< /p>

Before applying latex paint, the wall must be properly treated, otherwise serious problems such as falling off, cracking, and blistering will occur after latex paint is applied. Nowadays, many people still use 821 putty when constructing putty. In fact, 821 putty is not resistant to water. When the wall contains water, 821 putty will absorb water and bubble, causing latex paint to bubble and fall off in a large area. Moreover, the better the performance and film-forming properties of latex paint, the more serious the problem will be. Therefore, when using milk paint, first use a back seal to seal the wall, and then use water-resistant putty to avoid the above problems.

When constructing latex paint, the paint should be stirred evenly, especially when using brightly colored products. If it is not stirred evenly, the dispersion of the color paste in the paint will be unstable or the color paste will precipitate after long-term storage. Improper construction will cause the surface to bloom, seriously affecting the decorative effect.

In addition, whether water can be added during latex paint construction and the amount of water must be strictly followed by the manufacturer's regulations. Because some manufacturers have fully considered the various needs of users when designing and developing latex paints and designed a variety of formulas. Some latex paints do not need to add water during construction, but adding water will destroy the various properties of the latex paint.

Note that brushing, roller coating and spraying can be used during construction. Any of the above methods can achieve the desired effect, but the viscosity of the latex paint needs to be adjusted so that it is easy to apply during construction. Brush, and there should be no obvious brush marks after brushing. If the viscosity is too high, the brush marks will be obvious. If the viscosity is too low, it will easily cause problems such as slag flow and poor covering power.

After construction is completed, tools should be cleaned with water in time, otherwise after the latex paint dries, it will be difficult to clean due to the water resistance of the paint film.

Comparison between imported latex paint and domestic latex paint:

The imported latex paint currently on the market is a high-end, high-priced paint. It is only slightly better than domestic latex paint in terms of leveling, fineness, color matching and open can status. Other indicators are comparable, but the price is 1-2 times higher than domestic latex paint. Some users of imported latex paint have misunderstood propaganda, such as 1 kilogram can paint more than 8 square meters, which is intended to tell people that the cost per square meter is not more expensive than domestically produced paint. But it is impossible for 1 kilogram to cover such a large area. If the coating is too thin, other properties will be difficult to guarantee. Generally, 1 kilogram of paint is enough to cover 5 square meters.

Moreover, some imported latex paints are actually produced by domestic joint ventures and labeled with the trademarks of foreign companies. There are also many domestic latex paints with better quality, but the price is much lower than imported paints, which is more suitable for ordinary families. It is best to use interior latex paint for home decoration.

How to choose latex paint according to different parts of the paint.

The function of latex paint is very important. Latex paint should be selected according to the different parts of the painting. For example, the latex paint used on the walls of bedrooms and living rooms requires strong adhesion, fine texture, resistance to differentiation and breathability. Good durability; latex paint in kitchens and bathrooms should be waterproof, mildew-proof, and easy to wash. Polyvinyl acetate paint (commonly known as latex paint) can be used in bedrooms, but for kitchens, toilets, and balcony ceilings that are prone to moisture, paints that are more resistant to scrubbing, such as strong ethylene-propylene or styrene-propylene latex paints

Why latex paints are much better than solvent-based paints:

Latex paints are water-based paints, and their film properties are much better than solvent-based paints. Half of the organic solvents in solvent-based paints are absorbed by water here Instead, the toxicity problem of organic solvents has basically been completely solved by latex paint. Latex paint is a film-forming substance made from some polymer aqueous solutions. In addition to water and different types of safe and harmless polymers or polymers, it also contains a small amount of emulsifier and a trace amount of unpolymerized free monomers. The free monomers are Some volatile small molecular substances have varying degrees of toxicity problems. Now the concentration of free monomers in environmentally friendly paints is controlled below 0.1%, and the dosage of additives is as high as 2% to 3%; as little as 0.1%. Between 05% and 0.1%. Nowadays, the toxic free monomer concentration and additive dosage of inferior latex paint exceed the standard by dozens or hundreds of times, which affects health. Nowadays, commonly used Nippon Paint and Dulux paints have reached the required environmental standards and are safe. There are currently many latex paint brands on the market, and imports and domestic products keep pace with each other, creating fierce competition. Domestic brands with guaranteed quality and good reputation are Red Lion and Kelan; imported brands are Dulux, Nippon Paint, Laiwei Paint, etc. The washing resistance of these brands is generally not less than 300 times, and some are as high as 2,000 times. If the imported brand is a "green product", it will have an international certification mark on the outer packaging, such as the "Blue Angel" mark in Germany; domestic products must have the words "Product certified by the China Environmental Labeling Product Certification Committee" to be called a "green product".
