Why paint paint is easy to deteriorate
1. What are the main components of paints and coatings?
The main components of paint include the following five parts:
Oil: including dry oil and semi-dry oil, is one of the main film-forming substances.
Resin: Including natural resin and artificial resin, it is also part of the main film-forming material.
Pigments: Including coloring pigments, extender pigments and anti-rust pigments. There are quite a variety of specific types, and they are secondary film-forming substances.
Thinner: Including solvents and diluents, used to dissolve the above substances and adjust the consistency, as an auxiliary film-forming substance.
Accessories: including drier, curing agent, plasticizer, moisture-proof agent. It also belongs to auxiliary film-forming substances.
2. Composition of decorative paint
mainly consists of three parts:
Main film-forming substances: also known as adhesives and fixing agents, which are the basis of coatings.
Secondary film-forming substance: it is also a component of the coating film, but it cannot leave the main film-forming substance to form the coating film alone
Auxiliary film-forming substances: including solvents and auxiliary materials. The former such as gasoline, e-liquid, rosin, benzene, ethyl acetate, acetone, etc.; the latter such as curing agent, emulsifier, tackifier, drier, wetting agent, dispersant, defoamer, initiator, catalyst , Stabilizer, anti-aging agent, antifreeze, etc.
paint composition
paint is traditionally called paint in China. The authoritative book "Paint Technology" in the Chinese paint industry defines it as follows: paint is a material that can be coated on the surface of an object with different construction techniques to form a solid, continuous solid with firm adhesion, certain strength, and film. The film formed in this way is generally called a coating film. Also called paint or coating. In the early days, most of the raw materials were mainly vegetable oil, so it was called paint. Regardless of the traditional coating products using natural materials as raw materials, or the coating products using synthetic chemical products as raw materials in modern development, they are all organic chemical polymer materials, and the coating film formed belongs to the type of polymer compounds. According to the modern classification of chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials, and they are an important industry in the chemical industry.
