Problems solved by technology

[0002] With the improvement of living standards, cars are becoming more and more popular. As a means of transportation widely used by people, people often have certain requirements for the durability of cars while pursuing comfort. Some paints sprayed on cars are often durable. Abrasion resistance, high temperature resistance and other properties are relatively poor, which brings great troubles to users
[0003] After retrieval, the Chinese patent application number is CN201310112606.X, which discloses a high-temperature-resistant powder coating and its preparation method. The components and their mass parts in the formula are: 27 parts of silicon-containing temperature-resistant resin, and the curing agent isofor 0.6-1 parts of ketone, 27 parts of 3307 resin, 0.8-2.0 parts of curing agent β-hydroxyalkylamide, 17 parts of talc, 21 parts of sericite, 1-2 parts of leveling agent, 1-3 parts of heat-resistant pigment , 0.1-0.2 parts of pure fluorine wax, 0.2-0.3 parts of aluminum oxide powder, the powder coating prepared by this formula has poor wear resistance and smoothness of the coating, and foam may be generated during spraying, which affects the spraying effect

Abstract

The invention discloses a high-temperature-resistant powder coating and a preparation method thereof, and relates to the field of powder coatings. The wear resistance, the smoothness and the sprayingeffect are improved; raw materials of the high-temperature-resistant powder coating comprise 500 parts of 9090 polyester resin, 60 parts of TGIC curing agent, 13 parts of 6088 leveling agent, 6 partsof 701B brightener and 10 parts of benzoin. The preparation method comprises the following steps: preparing the raw materials, namely weighing the 9090 polyester resin, the TGIC curing agent, the 6088leveling agent, the 701B brightener, benzoin, SA5066 hardening agent, a pigment agent, SA5060 defoamer and P600 calcium aluminate in parts by weight. P600 calcium aluminate is added into the raw materials, and due to the physical properties of high hardness and high melting point of the P600 calcium aluminate, the hardness after smearing can be increased during use, the high-temperature resistance and the wear resistance are improved, and the automobile maintenance frequency is reduced, so that money saved for users.
