摘要： 合成了可调控粉末涂料固化速度的聚酯树脂母粒，并将其应用到聚酯／ 异氰脲酸三缩水甘油酯（TGIC）粉末涂料中。运用 DSC 研究了其粉末涂料的固化曲线，同时对配制的粉末涂料进行涂层性能的测试。 结果表明：在保证粉末涂料优异耐冲击性的基础上，聚酯树脂母粒的加入可以降低粉末涂料的固化温度或缩短固化时间，从而减少能耗、降低成本。

Abstract: A polyester resin master-batch for changing the curing speed of powder coatings has been prepared which can be used in polyester/TGIC powder coatings. The curing curve of polyester/TGIC powder coatings was investigated by differential scanning calorimetry(DSC),and the film properties thereof was discussed. The result shows that with the adding of polyester resin master-batch, the powder coatings give lowered curing temperature and shortened curing time without sacrificing excellent impact property of the cured film, useful for reduction of energy consumption and cost.
