Abstract

The invention belongs to the field of metal powder coating, and particularly relates to fingerprint-resistant metal powder coating with a chromium plating effect. The fingerprint-resistant metal powder coating with the chromium plating effect comprises an epoxy resin particle system containing epoxy resin, adaptive curing agent A and chromium plating effect pigment, and a fluorocarbon resin particle system containing fluorocarbon resin and adaptive curing agent B, wherein the ratio of parts by weight between the epoxy resin particle system and the fluorocarbon resin particle system is 7-3/3-7. The fingerprint-resistant metal powder coating with the chromium plating effect forms an epoxy resin layer and a fluorocarbon resin layer which are separated in the solidification process, floating type aluminum powder is bonded regularly by means of a bonding process to form the chromium plating effect, the fluorocarbon resin layer at the outer layer has the functions of a transparent protective film, and the epoxy resin layer at the inner layer forms a bonding layer and is favorable for bonding with a layer to be coated.

Description

technical field [0001] The invention belongs to the field of metal powder coatings, in particular to a metal powder coating with chrome plating effect and anti-fingerprint performance 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. Metal powder coatings refer to various powder coatings containing metal pigments (such as: copper gold powder, silver aluminum powder, etc.). Because metal powder coatings can show a bright and luxurious decorative effect, they are very suitable for spraying indoor and outdoor objects such as furniture, accessories and cars. Metal powder coatings are widely use...
