Description

一种耐高温、耐候性好的粉末涂料及其制备方法
技术领域
本发明涉及一种粉末涂料，尤其是一种耐高温、耐候性好的粉末涂料。
背景技术
灯罩工件由于长时间受到高温光源的烘烤，极易发生损坏，极大的影响其使用寿命，通过高效的粉末涂层涂覆，可起到很好的保护效果。但是普通的粉末涂料耐温和耐候性差，易出现老化变黄、变形、脱落等情况。一种耐高温、耐候性好的粉末涂料可提供对灯罩的长时间的保护作用，延长使用寿命，降低损坏率，节约成本。
发明内容
本发明的目的就是为了提供一种耐高温、耐候性好的粉末涂料。
本发明是通过以下技术方案实现的：
一种耐高温、耐候性好的粉末涂料，其特征在于它是由以下重量份的原料制成：
环氧树脂25-35、聚酯树脂25-35、钛白粉26-38、复合填料8-12、功能助剂4-7。
其中，所述的复合填料为硫酸钡、硫酸钙、碳酸钙中的一种或多种。
其中，所述的功能助剂由以下重量组分原料组成：增光剂0.8-1.6、安息香0.4-1.2、蜡粉0.4-1.2、增电剂0.4-1.2、抗黄变剂0.5-1.5、流平剂1-2、抗泛黄消光剂0.4-1.2、氮化硼1-5。
其中，所述的氮化硼为六方晶型，熔点为3000 oC，平均粒度15 μm，热导率600-800W/mk，密度2.26g/cm3，振实密度0.32g/cm3。
一种耐高温、耐候性好的粉末涂料的制备方法，包括以下步骤：
将上述各原料混合，通过挤出机熔融挤出、压片、冷却、破碎后，再经过微粉碎机粉碎、过筛，即得所述耐高温、耐候性好的粉末涂料。
本发明的有益效果：
本发明的粉末涂料，粉体分散性好，涂层表面佳，机械性能好，耐高温，耐黄变，耐候性优异，绿色环保。可对灯罩提供长时间的保护，提高使用寿命，降低损坏率。
