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

Embodiment 1

[0023] Accurately weigh the raw materials used to prepare the super wear-resistant metal powder coating according to the weight percentage of the following components:

[0024] Polyester: 35%; Epoxy resin: 25%; Leveling agent: 1.0%; Brightener: 1.0%; Super wear-resistant additive: 15%; Silver powder: 3%; The acid value of said polyester is 40-75.

[0025] Put the above-mentioned weighed raw materials into a high-speed mixer for pre-mixing for 15 to 20 minutes, then put the resulting mixture into a high-speed extruder, knead and extrude at a temperature of 115°C to 135°C, and then press After the flakes are crushed, they are crushed into powder particles with a particle size of 25 to 40 microns by an ACM micro-pulverizer, and then the powder particles are passed through a 140-mesh sieve, inspected and packaged to obtain a finished super wear-resistant metal powder coating.

[0026] Apply the super wear-resistant metal powder coating obtained above to the surface of the product...

Embodiment ２

[0028] Accurately weigh the raw materials used to prepare the super wear-resistant metal powder coating according to the weight percentage of the following components:

[0029] Polyester: 25%; epoxy resin: 35%; leveling agent: 1.0%; brightener: 0.5%; super wear-resistant additive: 12%; silver powder: 1.5%; coupling agent: 15%; crosslinking agent : 10%; wherein, the acid value of the polyester is 40-75.

[0030] The preparation method is consistent with the method in Example 1, and will not be repeated here.

Embodiment ３

[0032] Accurately weigh the raw materials used to prepare the super wear-resistant metal powder coating according to the weight percentage of the following components:

[0033] Polyester: 32%; epoxy resin: 28%; leveling agent: 1.5%; brightener: 1.5%; super wear-resistant additive: 8.0%; silver powder: 1.0%; coupling agent: 20%; crosslinking agent : 8.0; wherein, the acid value of the polyester is 40-75.

[0034] The preparation method is consistent with the method in Example 1, and will not be repeated here.

Abstract

The invention relates to a super wear-resistant metal powder coating, and belongs to the technical field of coating materials. Aiming to solve the technical problems of poor wear resistance and low product hardness in the prior art, the invention provides the super wear-resistant metal powder coating which is mainly prepared from the following components by weight percent: 25 to 35 percent of polyester; 25 to 35 percent of epoxy resin; 0.5 to 1.5 percent of flatting agent; 0.5 to 1.5 percent of brightening agent; 5.0 to 15 percent of super wear-resistant additive; 1.0 to 3.0 percent of silver powder; 15 to 20 percent of coupling agent; and 5.0 to 10 percent of crosslinker. After being coated with the coating provided by the invention, the surfaces of products achieve high hardness which can be above 3H, and after rubbing against each other for thirty times, the surfaces of the products are not abraded, thereby having strong wear resistance; and the super wear-resistant metal powder coating has high stability and cohesiveness.

Description

technical field [0001] The invention relates to a coating, in particular to a super wear-resistant metal powder coating, which belongs to the technical field of coating materials. Background technique [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 hard...
