The chemical composition of paint, the main chemical composition of paint

I don't know if you're asking about paint. The main components of paint include the following five parts:

1.Oil: including dry oil and semi-dry oil, is one of the main film-forming substances.

2.Reins: including natural resins and artificial resins, which are also part of the main film-forming substances.

3.Pigments: including coloring pigments, physique pigments and anti-rust pigments, there are many specific varieties, which are minor film-forming substances.

4.Thinner: including solvent and diluent, used to dissolve the above substances and adjust the consistency, as an auxiliary film-forming substance.

5.Excipients: including drying agents, curing agents, plasticizers, moisture-proof agents. It is also an auxiliary film-forming substance.

The chemical composition of each lacquer is different.

Hello Qinqin paint is composed of three kinds of substrate pre-materials: film-forming substances, secondary film-forming substances and auxiliary film-forming substances. Among them, the film-forming substance is made of organic polymer compounds such as coatings, jujubes, natural resins and other ingredients, and is made of inorganic combined paint at high temperature during processing. Secondary film-forming substances mainly include various pigments, physique pigments, and anti-rust pigments.

The auxiliary film-forming substances mainly include various additives and solvents, and the increase of an appropriate proportion can reduce the phenomenon of non-drying, sinking bottom agglomeration, crusting and other phenomena when the paint collapses, and can also protect the paint from damage during storage and transportation.

They are all composed of three basic substances: film-forming substances, secondary film-forming substances and auxiliary slippery membrane substances.

English name: paint or coating. Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, signs and other special purposes.

The authoritative book "Coating Technology" in China's coating industry is defined as follows: "Coating is a material that can be coated on the surface of objects with different construction techniques to form a solid adhesive, strong and continuous solid thin film. The film formed in this way is commonly known as the coating film, also known as the paint film or coating.

> coatings are generally composed of four parts: film-forming substances, fillers (pigments and fillers), solvents, and additives. Depending on the performance requirements, sometimes the composition will change slightly, such as no pigment and filler in the varnish, and no solvent in the powder coating.

It is an organic chemical polymer material, and the coating film formed belongs to the type of polymer compound. According to the classification of modern 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.

Regardless of the variety or form, paint is composed of three basic substances: film-forming substances, secondary film-forming substances and auxiliary film-forming substances.

1. Film-forming substances.

Film-forming substances, also known as binders, are mostly organic polymer compounds such as natural resins (rosin, lacquer), coatings (tung oil, linseed oil, soybean oil, fish oil, etc.), synthetic resins and other mixed ingredients, which are formed by high-temperature reaction, and there are also inorganic paints (such as inorganic zinc-rich paint). It is the main body that constitutes the paint and determines the performance of the paint film.

2. Secondary film-forming substances.

Secondary film-forming substances include various pigments, physique pigments, and antirust pigments. Pigments provide color and hiding power for paint films, improve the protective properties and decorative effects of paints, and pigments with good weather resistance can improve the service life of paints. Physique pigments can increase the thickness of the paint film, improve the waterproofness and anti-rust effect.

Anti-rust pigments can prevent the surface of objects from being corroded by the atmosphere, chemicals, and metal surfaces from being corroded.

3. Auxiliary film-forming substances.

Auxiliary film-forming substances include various additives, solvents, and various additives play a very important role in the production process, storage process, use process, and the formation process of paint film. Although the amount used is very small, it has a great impact on the performance of the paint film. It can not even be shaped into a paint film such as:

It does not dry, sink to the bottom, clumps, and crusts.

Extended Materials. First, the field of application.

Paint is an ancient name; Coating, is the name of modern civilization, contains more scientific and technological components, and is widely used in modern science and technology and industrial fields. However, there are some customary names for paint that are still retained, such as latex paint, primer, topcoat, etc.

Generally speaking, a coating is a material that can be applied to the surface of the coated object and can form a continuous film that adheres firmly. It can be both inorganic, such as electroplating copper, electroplating nickel, electrogalvanizing, etc. It can also be organic, such as most organic polymer materials, which constitute a major part of today's coatings market.

Second, the function of the material.

1. Protection function: anti-corrosion, waterproof, oil-proof, chemical-resistant, light-resistant, temperature-resistant, etc. Objects are exposed to the atmosphere and are eroded by oxygen and moisture, resulting in metal rust, wood decay, cement weathering and other damage phenomena.

Coating the surface of the object to form a protective film can prevent or delay the occurrence and development of these damages, so that the service life of various materials can be extended.

2. Decorative function: color, luster, pattern and flatness, etc. Objects of different materials can be coated with paint, which can get a colorful and colorful appearance, play a role in beautifying the living environment of human beings, and make contributions to the material life and spiritual life of human beings that cannot be ignored.

3. Other functions: marking, anti-fouling, insulation, etc. For modern coatings, this role is increasingly important compared to the first two.

Summary. Paint is composed of three basic substances: film-forming substances, secondary film-forming substances and auxiliary film-forming substances. Among them, the film-forming substance is made of organic polymer compounds such as paint and natural resin mixed with some ingredients, and the inorganic compound paint is made at high temperature during processing.

Secondary film-forming substances mainly include various pigments, physique pigments, and anti-rust pigments. The auxiliary film-forming substances mainly include various additives and solvents, and the increase of the appropriate proportion can reduce the phenomenon of non-drying, sinking bottom agglomeration, crusting, etc., and can also protect the paint from damage during storage and transportation.
