What are the most commonly used paints for home decoration and what are the classifications of inter

1. The coatings commonly used in the process of home decoration mainly include the following:

1. Low-grade water-soluble coatings: 106 and 803 coatings are common.

2. Latex paint: the common paint on the market is divided into two types: high and low. This type of lacquer is characterized by mercerized and satin-like paint, and it is generally painted twice.

Low-grade ones include Meishili, Shishili, etc., and this kind of paint can be painted directly without priming. Strong hiding power, soft and long-lasting color, easy to apply and cleanable. The paint can be selected according to personal preference, the lighting of the room, the size of the area and other factors.

3. Colorful spraying: Colorful spraying is dispersed in water in the form of oil-in-water, and once sprayed, a variety of color patterns can be formed, and the patterns are elegant and generous, with a three-dimensional sense. And the coating has good oil resistance and alkali resistance, and can be washed.

4. Paste interior wall paint (melamine coating): The advantage of melamine paint is that the surface is delicate, smooth and clean like porcelain, and it is not powdered, non-toxic, tasteless, good air permeability, and low price. However, the temperature resistance and scrubbing resistance are poor.

Second, with the development of technology, there are likely to be many different types of home decoration coatings, but generally only a slight technical change, roughly or the common type of paint on the market.

1 According to the classification of the use of the building, it can be divided into: exterior wall coatings, interior wall coatings, ground coatings, ceiling coatings, door and window coatings, etc.

2. According to the nature of the main film-forming substances, it can be divided into: organic coatings, inorganic coatings, organic-inorganic composite coatings, etc.

3 According to the state of coatings, it can be divided into: solvent-based coatings, water-soluble coatings, emulsion coatings, powder-based coatings, etc.

4. According to the special performance classification of coatings, it can be divided into: waterproof coatings, fireproof coatings, mildew coatings, insecticidal coatings, sound absorption or sound insulation coatings, heat insulation and thermal insulation coatings, anti-radiation coatings, anti-condensation coatings, anti-rust coatings, etc.

5. According to the classification of paint and coating film, it can be divided into: thin coating, thick coating, sand wall coating, color multilayer concave and convex pattern coating, etc.

6. According to the comprehensive base price classification, it can be divided into: wood paint, metal paint, plastering paint, coating, etc.

Wall decoration occupies a larger area of home decoration, the effect is closely related to the overall effect, there are many types of paint styles on the market, but many decoration whites because of the first decoration, do not know what interior decoration paints are, and then briefly introduce the relevant knowledge for you.

1. Latex paint.

The main raw materials of latex paint are mainly synthetic resins, which belong to water-dispersible green environmental protection coatings, no harmful substances need to be added in the manufacturing process, and the safety performance is high.

2. Water-based paint.

Water-based paint does not contain organic solvents, has many advantages such as easy to use, green environmental protection, non-toxic, harmless, plump paint film, good water resistance, wear resistance, etc., and is widely used in buildings, homes, glass, metal and other areas.

3. Water-soluble coatings.

These coatings work by dissolving polyvinyl alcohol in water and adding other additives such as pigments. It has the advantages of cheap, non-toxic, odorless, convenient construction, etc., but it is not resistant to water and alkali, and the coating is easy to peel off after being wet, which is a low-grade decorative coating product, mainly used for the decoration of interior walls. Water-soluble coatings account for about 50% of the market, and are mostly used for low-end room decoration.

4. Liquid wallpaper.

Liquid wallpaper is what we often call wallpaper paint, it is a collection of wallpaper and latex paint characteristics as one of the environmentally friendly water-based coatings, its color is uniform, glossy, good decorative effect, has a strong water resistance, acid and alkali resistance, but also has the advantages of antibacterial, moisture-proof, no cracking, not easy to age, etc., but the overall ** is relatively high, and the construction is difficult.

5. Diatom mud.

Diatom mud is believed to be familiar to everyone, mainly using natural and environmentally friendly diatomaceous earth as raw materials. It does not contain any harmful substances, and the color is soft and durable, and it can also purify the air, breathe and humidify, fire and flame retardant, sound absorption and noise reduction, etc., but its texture is relatively rough, slightly higher.

According to the product form, it can be divided into liquid coatings, powder coatings and high-solid coatings.

According to the film-forming material (natural resin paint, phenolic paint, alkyd paint, amino paint, nitro paint, epoxy paint, chlorinated rubber paint, acrylic paint, polyurethane paint, silicone resin paint, fluorocarbon resin paint, polysiloxane paint, vinyl resin paint.

According to the type of substrate, it can be divided into organic coating, inorganic coating and organic-inorganic composite coating. Due to the different solvents used, organic coatings can be divided into organic solvent-based coatings and organic water-based (including water-emulsion and water-soluble) coatings. Common paints in life are generally organic paints.

Inorganic coatings. Refers to coatings made of inorganic polymer materials, including water-soluble silicates.

system, silica sol.

systems, silicones and inorganic polymer systems. Organic-inorganic composite coatings are available in two composite forms. One is to form a composite coating based on organic and inorganic materials. The other is the combination of organic coatings and inorganic coatings during decoration and construction.

According to the decorative effect, it can be divided into:1. Flat coating with a smooth surface (commonly known as flat coating), which is the most common construction method; 2.Sand wall paint with a sand-like decorative effect on the surface, such as real stone paint.

3.Multi-layer coatings such as embossing form a three-dimensional decorative effect of concave and convex patterns.

According to the parts used in the building, it can be divided into interior wall coatings, exterior wall coatings, ground coatings, door and window coatings, and ceiling coatings.

Classified according to the use function: it can be divided into ordinary coatings and special functional architectural coatings (such as fireproof coatings, waterproof coatings, mildew coatings, road sign coatings, etc.). ).

Depending on the color effect: such as metallic paint, natural paint (or solid paint), transparent varnish, etc.

In home decoration, paint is one of the indispensable materials, now there are many kinds of paint on the market, so that many consumers are very confused when purchasing, so, what are the types of paint? What are the main features of coatings? Next, I will introduce it to you, let's take a look.

Coating refers to a liquid or powder material, which can be coated on the surface of an object through a specific construction process, and form a firm adhesion after drying and curing, with a certain strength, continuous solid coating film, which has protection, decoration or other special functions for the coated object.

1. Paint type 1: water-soluble coating.

It belongs to low-grade products, is polyvinyl alcohol dissolved in water, and then added pigments and other additives in it, there are many brands of this kind of paint in the market at present, the main products are interior wall coatings, this kind of paint has many defects such as not resistant to water, not alkali, and the coating is easy to peel off after being wet, so it belongs to low-grade interior wall decorative coating products, mainly used for interior wall decoration; However, this kind of coating still has many advantages, such as cheap, non-toxic, odorless, convenient construction and other advantages, and this kind of coating is also quite convenient in the construction process, the current consumption is still the largest, accounting for about 50% of the market, mostly for the low-end room or temporary room interior wall decoration selection. 2. Paint type 2: latex paint coating.

It is a kind of water as the medium, acrylates, styrene-acrylate copolymers, vinyl acetate polymers as the film-forming substance, adding a variety of auxiliary components to make, the film-forming material is insoluble in water, the water resistance and weather resistance of the coating film is greatly improved than the first category, no trace is left after wet scrubbing, and there are different decorative types such as flat light and high gloss. Although this kind of coating material is more expensive, it occupies an increasing market share because of its excellent performance and decorative effect. A good latex coating layer has good resistance to water, alkali and scrubbing, and the coating will never peel off after being wet.

Generally speaking, (under the same pigment, volume and concentration conditions), styrene acrylic latex paint has better water, alkali resistance and scrub resistance than ethylene propylene latex paint, and ethylene propylene latex paint is better than polyvinyl acetate latex paint (commonly known as latex paint). 3. Paint type 3: colorful paint.

Colorful paint is the most sought after decoration coating in the market, the film-forming substance of the coating is nitrocellulose, which is dispersed in the water phase in the form of oil-in-water, and a variety of color patterns can be formed by spraying; But at present, a new type of coating material has appeared, the decorative effect of this kind of coating material is delicate, smooth and elegant, and it is not high, but the construction process is complicated and the wet friction resistance is poor.

Fourth, the characteristics of coatings.

1) Protective: protect the coated object from the erosion of harmful substances, so that the coated object can prolong its service life;

2) Decorative: make the coated object more beautiful;

3) Special functions: such as fluorescent paint for signs, other flame retardant paints, anti-condensation paints and electrophoretic paints, etc.;

4) The performance of the coating can be divided into: the appearance of the coating and the low-temperature freeze-thaw property.

The above is an introduction to the types of coatings and the characteristics of coatings, I hope this article can help you.

Coating, in China, the traditional name is paint. The so-called coating is a continuous film coated on the surface of the object to be protected or decorated, and can form a firm adhesion with the coated object, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding corresponding additives, and a viscous liquid prepared with organic solvents or water.

1. The decorative effect of decoration coatings The decorative effect of buildings is determined by the three aspects of texture, line shape and color, of which the line shape is determined by the building structure and design scheme, and the texture and color can be determined by the coating. The gloss of decoration coatings is the physical properties of the coating, and in architectural decoration, different parts have different requirements for gloss. When choosing coatings, consideration should be given to the harmony between the selected coatings and the building and the surrounding environment, and to consider the complementary effect of the architectural appearance design.

2. Environmental protection is particularly important for architectural coatings, especially for interior wall coatings, because interior wall coatings are closely related to people's lives. With the development of society and the continuous improvement of the living standards of consumers, as well as the improvement of their own health status and quality of life, people are more yearning for health and environmental protection, and require indoor coatings to be environmentally friendly.

3. Durability is particularly important for architectural coatings, especially exterior wall coatings, which include weather resistance, stain resistance, water resistance, etc. The coating of exterior wall paint is exposed to the atmosphere all year round, and it has to withstand the climate change of the four seasons of the year, under the external action of sunlight, wind and rain, cold and heat, etc., the coating is prone to cracking, chalking, discoloration, blistering, falling off, staining and other drawbacks, which will make the coating lose its original decorative effect and protection function, and the coating becomes unrecognizable, which will seriously affect the appearance of the building and destroy the cityscape.

4. Coating can avoid defects such as uneven color, monotonous color, spot defects and other defects during the molding and processing of plastic products, and it is easy to produce problems such as aging and brittleness, scratches, stains, and static electricity. However, due to the fact that plastic is a low surface energy substance, its surface coating is much more difficult than that of steel, wood, construction and other surface coatings, and adhesion has become a major obstacle restricting the development of plastic coatings. Different formulations of coatings need to be selected according to different plastic substrates in order to produce better adhesion.

According to the type of binder: it can be divided into organic coatings, inorganic coatings, and organic-inorganic composite coatings. Due to the different solvents used, organic coatings are divided into two categories: organic solvent-based coatings and organic water-based (including water emulsion and water-soluble) coatings.

Common paints in life are generally organic paints. Inorganic coatings refer to coatings produced with inorganic polymer materials as base materials, including water-soluble silicate, colloidal silica, silicone and inorganic polymers. There are two composite forms of organic-inorganic composite coatings, one is that organic materials and inorganic materials are used as base materials in the production of coatings to form composite coatings; The other is that organic coatings and inorganic coatings are combined with each other during decoration construction.

Classified according to the decorative effect: it can be divided into: 1

Flat and smooth surface coating (commonly known as flat coating), which is the most common construction method; 2.sand-wall-like paint with a sand-grained decorative effect on the surface, such as real stone paint; 3.Multi-layered paints that form a three-dimensional decorative effect of concave and convex patterns, such as reliefs.

Classified according to the use part of the building: it is divided into interior wall coatings, exterior wall coatings, floor coatings and ceiling coatings.

Classified according to the use function: it can be divided into ordinary coatings and special functional architectural coatings (such as fireproof coatings, waterproof coatings, mildew coatings, road marking coatings, etc.).

Classified according to the color effect used: such as metallic paint, transparent varnish, etc.

Attention needs to be paid to home decoration brush paint.

Clean the wall: Use a spatula to remove the loose layer of putty from the wall. The putty layer that cannot be removed with a shovel can be gently tapped with a small hammer, and if there is no hollow drum sound, and the place that is still not loose after knocking can retain the original base layer.

Cleaning the wall: clean the surface of the floating dust and oil.

Repair the wall: Use water-resistant putty to repair the local damage and level the entire wall.

Primer: After the putty layer is fully cured and solidified and dry, apply 1-2 times of primer to prevent leakage.

Apply the topcoat: Once the primer is completely dry, apply the topcoat twice. It is forbidden to mix too much water when the paint is painted, especially the dark color paint mixed with too much water may lead to undesirable phenomena such as floating color and blooming.
