Abstract

The invention belongs to the field of metal powder coatings, and in particular relates to a metal powder coating for enhancing a flash effect. The metal powder coating for enhancing the flash effect comprises an epoxy resin particle system containing epoxy resin, a correspondingly adaptive curing agent A and flash metal pigment, and a fluorocarbon resin particle system containing fluorocarbon resin and an adaptive curing agent B. The weight part ratio of the epoxy resin particle system to the fluorocarbon resin particle system is (6-4):(4-6). According to the metal powder coating for enhancing the flash effect disclosed by the invention, thick aluminium-silver powder is successively bonded into an epoxy resin layer by using a binding process, so that the thick aluminium-silver powder is deposited in the bottom layer of a coating together with the epoxy resin layer in the curing process and cannot float in the surface layer of the coating; and a transparent fluorocarbon resin layer floating to the upper layer plays a role of protecting oxidative resistance of flash metal powder.

Description

technical field [0001] The invention belongs to the field of metal powder coatings, in particular to a metal powder coating with enhanced flash effect and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's requirements for comfort and aesthetics in their own living areas are also getting higher and higher, which makes the application of metal powder coatings in the entire decorative coating more and more widely. At present, it is the mainstream product of powder for art decoration. At the same time, metal powder coatings are widely used in indoor and outdoor metal furniture, lamps, handicrafts, range hoods, baby carriages, sports equipment and other industries because of their low pollution and convenient spraying process. Metal powder coatings refer to various powder coatings containing metal pigments (such as: copper gold powder, silver aluminum powder, etc.). Because ...
