Abstract

The invention discloses a wear-resistant powder coating, which is composed of the following raw materials in parts by weight: 20-30 parts of bisphenol F epoxy resin, 40-50 parts of aliphatic glycidyl ether epoxy resin, 10-15 parts of poly (meth)acrylic resin with free carboxyl, 2-3 parts of magnesium carbonate, 5-9 parts of rubber powder, 10-15 parts of carbon black, 2-3 parts of aluminum powder, 3-5 parts of iron oxide red, 3-4 parts of a curing agent, 0.7-1.2 parts of a stabilizer, 3-4 parts of a flatting agent, and 30-40 parts of non-slip wear-resistant powder, wherein the non-slip wear-resistant powder is a mixture of emery, hollow ceramic micro-powder and colloidal graphite powder. The powder coating disclosed by the invention is moderate in volume resistance, high in surface resistance, and good in wear resistance.

Description

technical field [0001] This invention relates to powder coatings. Background technique [0002] At present, with the rapid development of global industry, the environmental problems caused are becoming increasingly prominent. How to carry out environmental protection work has become an important subject to be studied urgently. Some western countries with strong environmental awareness have developed and researched automotive coatings with low volatile organic compounds, and put them into production and use in large quantities. With the continuous development of the automobile industry, in order to beautify the appearance of the automobile coating film and reduce the environmental pollution caused by it, it is particularly important to improve the automobile spraying technology. [0003] For automotive powder coatings, if the volume resistance of the powder coating is too high, the powder will not be easily adsorbed on the substrate, and if the volume resistance is too...
