Problems solved by technology

[0003] Most of the current topcoats are solvent-based, which requires the use of a large amount of organic solvents. The volatilization of organic solvents will cause serious environmental pollution problems. In addition, solvent-based topcoats also have safety problems in transportation, storage and use.
[0004] Chinese patent CN 102108244A discloses a high-elongation aliphatic polyurea topcoat and its preparation method. The topcoat consists of two components, A and B, and the composition ratio of component A is isophorone polyisocyanate 10 ~20%, HDI biuret polyisocyanate 40~50%, solvent 40~50%, the composition ratio of component B is polyaspartic acid ester resin 10~30%, pigment and filler 15~40%, additives 2 to 4%, solvent 20 to 50%, the topcoat of the invention contains a large amount of solvent, and the solvent volatilizes a lot during construction, so it will cause a large release of VOC in the construction process, pollute the environment, and be harmful to human health

Abstract

The invention relates to a weather-resistant and high-ductility finish paint. The weather-resistant and high-ductility finish paint is composed of a white paste, a black paste, an organosilicon leveling agent, an acrylic acid leveling agent, an ultraviolet light absorber, a light stabilizer and an adhesion promoter, wherein the white paste comprises titanium dioxide, a dispersant and polyasparticacid ester resin; and the black paste comprises carbon black, a dispersant and polyaspartic acid ester resin. The weather-resistant and high-ductility finish paint provided by the invention has the advantages of weather resistance, water resistance, salt spray resistance, wear resistance, high hardness, favorable fullness, favorable leveling property, favorable adhesive force and high tensile strength, and has the characteristics of high solid content, low viscosity, no solvent, greenness and environmental friendliness during spraying construction.

Description

technical field [0001] The invention belongs to the technical field of coating chemicals, and in particular relates to a weather-resistant and high-extensibility finish paint. Background technique [0002] The topcoat is the outermost coating of the painting, and the overall effect after painting is reflected through this layer. Therefore, there are high requirements for the materials used, which should have good resistance to external conditions. Such as weather resistance, water resistance, solvent resistance, etc., must also have the necessary decorative properties, such as excellent gloss, leveling, fullness, etc. [0003] Most of the current topcoats are solvent-based, which requires the use of a large amount of organic solvents. The volatilization of organic solvents will cause serious environmental pollution problems. In addition, solvent-based topcoats also have safety problems in transportation, storage and use. [0004] Chinese patent CN 102108244A discloses a hig...
