一种低温固化的汽车铝轮毂专用底粉粉末涂料及其制备方法
摘要：
本发明公开了一种适合于低温固化的汽车铝轮毂专用底粉粉末涂料，主要由低温固化聚酯树脂、环氧树脂和潜伏性促进剂组成。本发明还公开该粉末涂料的制备方法。该粉末涂料可以在150~160℃固化，并且保证极佳的流平性和抗结团性能，满足汽车铝轮毂涂装的镜面效果要求，并且具有优异的平衡块粘贴性能和透气性，不仅实现了低温固化，降低了铝轮毂涂装的能耗，还增加了铝轮毂的韧性。
摘要（英）：

The invention discloses a special low-temperature cured body powder coating for an aluminum wheel of an automobile, which consists of low-temperature cured polyester resin, epoxy resin and a latent accelerator. The invention further discloses a preparation method of the powder coating. The powder coating can be cured at 150-160 DEG C and extremely good levelling property and anti-caking performance are ensured, so that requirement for the mirror surface effect of aluminum wheel coating of the automobile is satisfied. Moreover, the coating has excellent counterbalance adhering performance and air permeability; low-temperature curing is achieved, the energy consumption for coating the aluminum wheel is reduced, and the toughness of the aluminum wheel is increased.
