preparation example Construction

[0020] The preparation method of metal powder of the present invention is as follows:

[0021] A. Mix E42 epoxy resin, polyethylene wax, zinc powder and copper powder at high speed;

[0022] B, the mixture in the step A is melt-extruded, crushed and screened to obtain a sieve;

[0023] C. Mix the screened product in step B with pigments, fillers, accelerators, and brighteners at high speed, and obtain a metal powder coating after screening.

[0024] Concrete each component composition for each component in the above-mentioned method is as follows:

Embodiment 1

[0026] 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, 2 parts of brightener.

Embodiment 2

[0028] 65 parts of E42 epoxy resin, 1.5 parts of zinc powder, 1.5 parts of copper powder, 7 parts of polyethylene wax, 4 parts of pigment, 1.5 parts of filler, 0.3 parts of accelerator, and 3 parts of brightening agent.

Abstract

The invention discloses a bright metal powdery coating. The bright metal powdery coating comprises, by mass, 60 to 70 parts of E42 epoxy resin, 1 to 2 parts of zinc powder, 1 to 2 parts of copper powder, 6 to 8 parts of polyethylene wax, 3 to 5 parts of a pigment, 1 to 2 parts of a filler, 0.2 to 0.5 parts of an accelerator, and 2 to 5 parts of a brightener. The bright metal powdery coating is prepared from simple raw materials through simple processes. Through use of the brightener, the brightness of the metal powder is improved and industrial production is convenient.

Description

technical field [0001] The invention relates to a metal powder coating, in particular to a bright 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 insufficient brightness, insufficient aesthetics of the product, poor use effect, a...
