摘　　要：研究了硅灰石在环氧聚酯粉末涂料中的应用情况,测试了硅灰石的添加量对漆膜光泽、硬度、附着力及耐热温度的影响。结果显示,在配方中添加一定比例的硅灰石可有效提高漆膜的硬度和耐热温度,但是对于光泽的影响比较严重。In this paper, the application of wollastonite in epoxy polyester powder coating was studied, and the influence of wollastonite addition on gloss, hardness, adhesion and heat resistance of paint film was tested. The results show that the addition of wollastonite in the formula can effectively improve the hardness and heat resistance of the paint film, but has a noticeable influence on the gloss.
