摘要
研究了三羟甲基丙烷、二甘醇和乙二醇对聚酯树脂消光性能的影响,制备了一种适用于聚酯/环氧体系亚光粉末涂料用60/40聚酯树脂,同时针对该聚酯在亚光粉末涂料中的应用展开了与消光剂适应性和烘烤炉温适应性的研究.试验结果表明:合成的60/40消光聚酯与不同种类消光剂匹配性好,同时烘烤炉温波动对粉末涂料性能影响较小,利用该聚酯制备的亚光粉末涂料还具有良好的机械性能和平整细腻的外观.
Abstract
The effects of trimethylolpropane,diethylene glycol,and ethylene glycol on the matting properties of polyester resin were studied,and a 60/40 polyester resin suitable for polyester/epoxy system matting powder coatings was prepared.At the same time,the application of this polyester in matting powder coatings was studied for its adaptability to matting agents and baking furnace temperature.The experimental results show that the 60/40 matte polyester synthesized in this article has good compatibility with different types of matte agents,and the fluctuation of baking furnace temperature has little impact on the performance of the powder coating.The matting powder coating prepared using this polyester also has good mechanical properties and a smooth and delicate appearance.
