Abstract

The invention relates to high temperature-resistant powder coating and a preparation method thereof. The high temperature-resistant powder coating comprises graphene modified epoxy resin, graphene modified polyester resin, a curing agent, a mica powder, a talc powder, hollow microbeads, a defoamer, a leveling agent, a high temperature-resistant pigment and other auxiliary agents. According to thetechnical scheme, through the addition of the hollow microbeads in the coating, by virtue of the characteristic of good fluidity of the hollow microbeads, the high temperature resistance of the powdercoating is effectively improved; the film forming hardness of the powder coating is adjusted through different hardness of the graphene modified epoxy resin and the graphene modified polyester resin,and through different contents of graphene in the epoxy resin and the polyester resin, after mixing, a bonding force inside the material can prevent reaggregation of the graphene because of capability of forming a disordered structure in a coating layer of the coating and increases the resistance of permeability factors permeating to the surface of a substrate, so that the corrosion resistance ofthe coating is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of powder coatings, in particular to a high-temperature-resistant powder coating and a preparation method thereof. Background technique [0002] Metal corrosion not only brings economic losses to human beings, but also is not conducive to the protection of natural resources and the environment, and sometimes even endangers personal safety. In order to prevent and slow down corrosion, many anti-corrosion methods have been developed in production practice and scientific experiments. Among them, paint protection is the most convenient and economical, so it has been widely used. [0003] In order to improve the anti-corrosion performance of coatings in various environments, there are many improvement technologies for coatings, such as adding components such as graphene into coatings to improve the performance of coatings. However, in the prior art, the anti-corrosion performance of coatings in high-temperature ...
