Paint is used in the surface of the object and can form a tough protective film of the general term, architectural paint is an important category in the paint, in China, will generally be used for building walls, walls, roof, ground, bathroom Find compositions. Refither composition Results Rhithers. Ref 员sy composition composition Results Results:

Architectural pigments have decorative functions, protection functions and living improvements. The proportion of the various functions varies depending on the purpose of use. The decorative function is the function of improving the appearance value through the beautification of the building. Mainly including the plane color, pattern and gloss of the concept of design and design of the three-dimensional pattern design. But with the shape of the building itself and the size and shape of the substrate itself to match, to fully play out. Protection is a function that protects buildings from environmental influences and damage. Different types of protected body requirements for the protection of the content is also different. Such as indoor and outdoor coating required to achieve the difference between the indicators is great. Some buildings have special requirements for mold, fire, heat insulation, corrosion resistance and so on. Resident improvement is mainly for indoor painting, is to help improve the living environment of the function, such as sound insulation, sound absorption, anti-condensation and so on.

The composition of the paint

1, film-forming material: film-forming material is the basis for the composition of paint, it plays a decisive role in the nature of the paint. Can be used as a lot of film coating material varieties, can be divided into two types of conversion and non-conversion type. Conversion coating film-forming materials are mainly dry oil and semi-dry oil, two-component amino resin, polyurethane resin, alkyd resin, thermosetting acrylic resin, phenolic resin and so on. Non-conversion coating film mainly nitrocellulose, chlorinated rubber, asphalt, modified rosin resin, thermoplastic acrylic resin, vinyl acetate resin.

2, pigments and fillers: paint can make the paint showing a rich color, so that the coating has a certain hiding power, and has enhanced mechanical properties and durability of the coating. Many varieties of pigments, in the preparation of paint should be noted in accordance with the requirements of the different performance and use carefully selected. Fill can also be called physical pigments, characterized by the basic does not have hiding power, mainly in the paint from the filling effect. The filler can reduce the cost of the coating, increase the thickness of the coating, and enhance the mechanical properties and durability of the coating. Commonly used filler varieties are talcum powder, calcium carbonate, barium sulfate, silica and so on.

3, solvent: In addition to a small number of solvent-free coatings and powder coatings, the solvent is an indispensable part of the paint. Commonly used organic solvents are mainly aliphatic hydrocarbons, aromatic hydrocarbons, alcohols, esters, ketones, halogenated hydrocarbons, terpenes and so on. The proportion of solvent in the paint is mostly above 50%. The main role of the solvent is to dissolve and dilute the film, so that the coating is easy to form in the construction of a more perfect paint film. Solvent in the paint after the end of the construction, are generally volatile to the atmosphere, rarely left in the paint film. In this sense, the paint in the solvent is a great pollution to the environment, but also a great waste of resources. Therefore, the modern coatings industry is working to reduce the use of solvents, developed a high solid paint, water-based paint, latex paint, solvent-free coatings and other environmentally friendly coatings. The company's many varieties of paint are environmentally friendly coatings.

4, additives: the image that the role of additives in the paint, it is equivalent to the role of vitamins and trace elements on the human body the same. Very little use, the role of great, indispensable. Modern paint additives mainly four major categories of products:

1) additives for the production of paint, such as defoamers, wetting agents, dispersants, emulsifiers and so on.

2) the role of the paint storage process additives, such as anti-settling agent, stabilizer, anti-skin agent.

3) the paint construction process of the role of additives, such as leveling agent, defoamer, driers, anti-sagging agent.

4) additives for the performance of the coating film, such as plasticizers, matting agents, flame retardants, fungicides and so on.
