Principle of different curing methods of floor paint film

  • Time of issue:2022-06-18 16:17

(Summary description)The polymerization and curing of floor paint is mainly through the action of oxygen, catalyst, ultraviolet ray, electronic ray, etc., to promote various types of polymerization and cross-linking chemical reactions of film-forming materials to form a network type polymer paint film.

Such coatings commonly used in parking lot floor paint include unsaturated polyester resin, modified acrylic resin, polyurethane paint, acid cured amino alkyd paint, etc.

What are the principles of different floor paint film curing methods? The principles of different floor paint film curing methods are as follows. Let's talk about the principles of various methods.

1、 Oxidation curing film forming

The oxidation curing of floor paint is the result of the combined action of the oxidation polymerization reaction between the film-forming substances and the physical process of solvent volatilization, but mainly the polymerization reaction. Parking lot floor paint this kind of paint is commonly used: grease paint (clear oil, ready mixed paint), ester rubber paint, calcium grease paint, oil-based phenolic resin paint and other oily paints containing a large amount of vegetable oil. Because the rate of oxidative polymerization is slower than that of solvent volatilization. Therefore, the curing rate of this kind of paint mainly depends on the oxidation polymerization reaction rate.

2、 Polymerization curing film forming

The polymerization and curing of floor paint is mainly through the action of oxygen, catalyst, ultraviolet ray, electronic ray, etc., to promote various types of polymerization and cross-linking chemical reactions of film-forming materials to form a network type polymer paint film.

Such coatings commonly used in parking lot floor paint include unsaturated polyester resin, modified acrylic resin, polyurethane paint, acid cured amino alkyd paint, etc.

3、 Volatilization curing film forming

Volatilization and curing of floor paint is mainly a physical process of solvent volatilization. With the continuous volatilization of the solvent, the viscosity of the coating gradually increases, changing from a flowing state to a non flowing state. After the volatilization of the solvent, the curing process of the coating is completed, forming a cured paint film. Such coatings are commonly used as shellac paint, nitrocellulose paint, overcoat and volatile acrylic paint.

When the same solvent volatilizes from the film-forming substance solution with good release, the parking lot floor paint volatilizes at the same speed within a certain time from the beginning to the end. However, in the film-forming material solution with poor release, the rate of volatilization decreases to a very low level in the late stage, and it takes a long time to volatilize part of the residual solvent.
