Abstract

The invention relates to the technical field of research and development of additives in powder coatings, and discloses a scratch-resistant agent for a powder coating. The scratch-resistant agent comprises the following components in parts by weight: 14-16 parts of ammonium nitrate, 11-13 parts of sodium laurate, 8-10 parts of zinc stearate, 5.5-6.0 parts of dibutyltin maleate, 1.5-1.8 parts of magnesium hydroxide, 1.3-1.5 parts of aluminum hydroxide, 1.0-1.2 parts of sodium bicarbonate, 0.3-0.5 part of a surfactant, 2.6-2.8 parts of sodium carbonate, 25-28 parts of paraffin wax, 0.2-0.4 partof silicone powder, 0.1-0.3 part of whisker silicon and 25-30 parts of anhydrous ethanol. The prepared scratch-resistant agent has high hardness and good flexibility, the surface hardness of a coatingis improved by modifying a molecular structure of a material, the surface smoothness of a coating film can be effectively increased, and the friction force is reduced.

Description

technical field [0001] The invention belongs to the technical field of research and development of additives in powder coatings, and in particular relates to an anti-scratch agent for powder coatings. Background technique [0002] Powder coating is a solvent-free, 100% solids powder coating. It has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. The application fields of powder coatings are very extensive. With the gradual development of coating production technology and the expansion of scale, the requirements for powder coatings are getting higher and higher. In order to improve the performance of powder coatings, people use various fillers and additives in the formula. way of medicine. During the processing and molding of coatings, different amounts of fillers are added to meet certain requirements. [0003] A need (reduce cost,...
