What are the classifications of coatings according to the main film forming substances

The main film-forming substances of coatings: mainly grease and resin, refers to the materials that can be coated on the surface of the object to form a film, and can make the coating firmly adhere to the surface of the coated object to form a continuous film.

Minor film-forming substances: pigments, fillers, and dyes are secondary film-forming substances. Pigments:

It refers to some fine powdery substances, which have the functions of making the paint display various colors and hiding power, adjusting the viscosity of the coating, increasing the thickness of the paint film, improving the mechanical strength and filling, and enhancing the durability and wear resistance of the paint film. According to the nature of pigments, they can be divided into: inorganic pigments, organic pigments, and physical pigments.

Pigments have tinting and hiding powers. The filler has a filling effect. The dye has tinting power and does not have hiding power.

Auxiliary film-forming substances: additives. It is used in small amounts in coatings, but can significantly improve the performance of coatings, such as dispersants, leveling agents, defoamers, thickeners, etc.

Coatings mainly have two kinds of materials, grease and resin, which refers to the materials that can be coated on the surface of the object to form a film, and can make the coating firmly adhere to the surface of the coated object to form a continuous film.

Water-soluble coatings are made of water-soluble resin as film-forming material and polyvinyl alcohol.

and its various modifiers as representatives, in addition to water-soluble alkyd resin, water-soluble epoxy resin.

and inorganic polymer water-based resins.

Water-dilution coatings refer to coatings formulated with post-emulsion as film-formers, so that the solvent-based resin is dissolved in an organic solvent.

Answer]: a, b, d

According to the properties of the main film-forming substances of coatings: organic coatings, inorganic coatings, and composite coatings.

It is divided into three types: oil, resin and inorganic cementitious material.

1. Oil: Introduction: Oilseed is the film-forming material used in the most filial piety of coatings, and it is the main material for the manufacture of oil-based coatings and oil-based coatings.

Oilseeds can be divided into vegetable oil, animal oil and mineral oil according to their **. According to whether it can consolidate and form a film and the speed of film formation, it is divided into dry oil, semi-dry oil and non-flexible oil. The oils used in coatings are mainly dry oils, such as tung oil, catalpa oil, linseed oil, soybean oil, etc.

2. Inorganic cementitious materials:

Introduction: Inorganic cementitious materials include coatings of traditional materials such as cement and lime. In addition, there are coatings that mainly use inorganic polymers as the composition substance, such as water-soluble silicate, that is, alkali metal silicate and other inorganic coatings. Sincerely.

3. Resin: Introduction: There are three types of commonly used resins for coatings, namely natural resins, artificial resins and synthetic resins.

Natural resins are naturally occurring, such as rosin, shellac, and resin. Artificial resins are processed from natural organic polymer compounds; Taicheng resin is prepared from monomers through polymerization reaction or condensation reaction. The coating made of synthetic resin has excellent performance and good gloss of the coating film, and is the largest output, the most varied and the most widely used coating in the modern coating industry.

Answer] :d architectural liquid roller decorative coating can be divided into three parts: main film-forming substance, secondary film-forming substance and auxiliary film-forming substance according to the role of each component in the coating. Among them, the main film-forming substance is also known as the residual adhesive.

Its function is to bond other components into a whole, and can firmly adhere to the surface of the coated substrate to form a tough protective film.

Answers]: a, c, d

Architectural coatings are divided into water-based coatings, solvent-based coatings, and art coatings according to the different chemical compositions of the main film-forming substances.

Water-based coatings include emulsion-type coatings, inorganic coatings, dust-based water-soluble coatings, etc.

Solvent-based coatings include acrylic coatings, polyurethane acrylic coatings, silicone acrylic coatings, etc.

Art finishing projects include indoor and outdoor coat color painting, knurling finishing, imitation pattern painting and other finishing projects.

There are 5 questions in total, (1), (2) and (3) are 20 points each, and (4) and (5) are 30 points each).

Answer]: C The mold block of this question is a decorative material. Secondary film-forming substances cannot be filmed alone, they include pigments and fillers.

Pigments are insoluble in water and oil, giving paints an aesthetically pleasing color. The filler can increase the thickness of the coating film and improve the wear resistance and hardness of the coating film. Let rot.

Summary. The main film-forming substances of asphalt paints include bitumen and resins. Among them, asphalt is a natural organic gum with good rheological properties at high temperatures, which can decompose and produce fatty acids in an oxygen atmosphere, so that the paint film increases rigidity and weather resistance.

Resin is a solid polymer compound with strong adhesion and chemical resistance, which can increase the strength and abrasion resistance of the paint film. Commonly used resins are alkyd resins, phenolic resins, amino resins, etc.

Excuse me, but please go into more detail?

The main film-forming substances of asphalt paints include bitumen and resins. Among them, asphalt is a natural organic gum, which has good rheological properties at high temperatures, and can decompose and produce fatty acids in an oxygen atmosphere, so that the paint film cavity increases rigidity and weather resistance. The resin is a solid polymer compound with strong adhesion and chemical resistance, which can increase the strength and abrasion resistance of the rubber blanking paint film.

The commonly used resins such as combustion are alkyd resin, phenolic resin, amino resin, etc.

Summary. Sprinkled green paint is a traditional paint, and the main film-forming substance is natural resin. Specifically, the main film-forming substances of sprinkled green paint include the following:

1.Agarwood resin: It is a commonly used natural resin with good durability and water resistance, which can make the paint film stronger and more durable.

2.Areca nut resin: It is also a commonly used natural resin that can increase the hardness and gloss of the paint film.

3.Red resin: It is a natural resin that grows in tropical areas and can make the paint film more flexible and wear-resistant.

4.Paint resin: It is a natural resin extracted from the paint tree, which can make the paint film brighter and more stable.

Sprinkled green paint is a traditional paint, and the main film-forming substance is natural resin. Specifically, the main film-forming substances of sprinkling green paint include the following:1

Agarwood resin: It is a commonly used natural resin with good durability and resistance to imitation blind water, which can make the paint film more strong and durable. 2.

Areca nut resin: It is also a commonly used natural resin that can increase the hardness and gloss of the paint film. 3.

Red resin: It is a natural resin that grows in tropical areas to make the paint film more flexible and wear-resistant. 4.

Paint resin: It is a natural resin extracted from the paint tree, which can make the paint film brighter and more stable.

Can you add, I don't quite understand it.

The above natural tree Huidani resin has good durability, water resistance and abrasion resistance, which can make the paint film sprinkled with green paint more stable and durable. It should be noted that because the sprinkled green paint contains more natural resin, its construction process requires certain skills and experience, otherwise it is prone to problems. It is recommended to understand some basic knowledge before applying hailwall, or consult a professional paint construction source.
