摘　　要：研究了三羟甲基丙烷不同用量及加料方式、2-甲基-1,3-丙二醇及偏苯三酸酐不同用量对聚酯树脂性能的影响;权衡了各单体的用量,制备了一种贮存稳定性好、起砂效果及机械性能优异的专用于β-羟烷基酰胺体系砂纹粉末涂料用的聚酯树脂;通过等温固化研究确定了砂纹粉末涂料的固化条件。The factors influencing the performance of polyester resin has been investigated, which including trimethylolpropane content and feeding method, 2-methyl-1,3-propylene glycol, and trimellitic anhydride content. A kind of polyester resin for sand grain powder coatings based on β-hydroxylalkyl amide which has good storage, sugaring effect and mechanical properties were prepared by weigh the monomer ration. The curing condition of sand grain powder coatings were determined by isothermal solidification.
