Problems solved by technology

[0003] However, the metal powder coatings that appear in the domestic market today generally have the defects of low hardness and non-wear resistance. The surface of the coating film will be destroyed after rubbing several times, resulting in a decrease in the aesthetics of the product and a decrease in service life. High product rate

preparation example Construction

[0019] The preparation method of metal powder of the present invention is as follows:

[0020] A. Mix E42 epoxy resin, polyethylene wax, zinc powder and copper powder at high speed;

[0021] B, the mixture in the step A is melt-extruded, crushed and screened to obtain a sieve;

[0022] C. Mix the screened product in step B with pigments, fillers, and accelerators at high speed, and obtain a metal powder coating after screening.

[0023] Concrete each component composition for each component in the above-mentioned method is as follows:

Embodiment 1

[0025] 60 parts of E42 epoxy resin, 1 part of zinc powder, 1 part of copper powder, 6 parts of polyethylene wax, 3 parts of pigment, 1 part of filler, 0.2 part of accelerator.

Embodiment 2

[0027] 65 parts of E42 epoxy resin, 2 parts of zinc powder, 2 parts of copper powder, 7 parts of polyethylene wax, 4 parts of pigment, 2 parts of filler, and 0.3 parts of accelerator.

Abstract

The invention discloses metal powder coating. The metal powder coating is characterized by comprising, by weight, 60-70 parts of E42 epoxy resin, 1-2 parts of zinc powder, 1-2 parts of copper powder,6-8 parts of polyethylene wax, 3-5 parts of pigment, 1-2 parts of fillers and 0.2-0.5 part of accelerators. The powder coating has the advantages that methods for the metal powder coating include simple manufacturing processes, raw materials for the metal powder coating are simple in structure, and accordingly industrial production can be facilitated.

Description

technical field [0001] The invention relates to a coating, in particular to a metal powder coating. technical background [0002] With the increasing variety of coating products and the continuous expansion of the application range, the coating industry has become an important independent industrial production part of the chemical industry. And in the coatings industry, powder coatings belong to the fastest growing category. Due to serious air pollution in the world, environmental protection laws and regulations are increasingly strict on pollution control, requiring the development of pollution-free and resource-saving coating varieties. Therefore, solvent-free, protective and decorative powder coatings have developed rapidly because of their economic and social benefits. [0003] However, the metal powder coatings that appear in the domestic market today generally have the defects of low hardness and non-wear resistance. The surface of the coating film will be destroyed ...
