Problems solved by technology

[0006] In particular, for the glass substrates that are widely used in the coating field, the surface is dense, the paint is difficult to penetrate, and the long-term adhesion between the paint film and the substrate is difficult to effectively guarantee; and the paint film has high requirements for resistance.
Therefore, the preparation of crack paints on glass substrates is extremely challenging

Abstract

The invention discloses a crack lacquer for a glass surface. The crack lacquer comprises the following raw materials in part by weight: 10-20 parts of alkyd resin, 20-50 parts of UV curing resin, 5-20 parts of UV curing monomer, 5-15 parts of fumed silica, 1-5 parts of photoinitiator, 1.5-10 parts of auxiliary material, 10-20 parts of mixed solvent and 5-10 parts of pigment, wherein the mixed solvent is a mixed solvent including cyclohexanone, acetone, ethyl acetate and butyl acetate. The crack lacquer for the glass surface, disclosed by the invention, has the advantages of environment friendliness, no pollution and short construction time; meanwhile, as films are cross-linked and cured, the crack lacquer for the glass surface, disclosed by the invention, has the advantages of great cross-linking strength and excellent resistance.

Description

technical field [0001] The invention relates to a paint, in particular to a crack paint for glass surfaces. Background technique [0002] Crack lacquer is a kind of nitro crack lacquer of various colors, which is prepared by grinding nitrocellulose, pigments, extender pigments, organic solvents, auxiliary agents, etc. It is a volatile self-drying paint, no need to add curing agent, and the drying speed is fast. Therefore, the crack paint must be on the surface of one or more layers of nitro paint with the same characteristics in order to fully integrate and exhibit another crack characteristic of the crack paint. Due to the high content of cracked paint powder and the high volatility of the solvent, it has large shrinkage and low flexibility. After spraying, the internal stress produces high tensile strength, forming a good and uniform crack pattern and enhancing the appearance of the coating surface. , to improve decoration. [0003] With the development of modern coatin...
