抗氧剂对 TGIC 固化型粉末涂料耐热性能的影响

摘要

研究了常见抗氧剂及其复配对粉末涂料涂层的耐热性能的影响，考查了在不同温度下涂层的外观、保光率、黄变指数的变化，初步探讨了粉末涂层的耐热机理。%The effect of antioxidants on the powder coatings was studied in this paper , the appearance , gloss retention and yellowing index of the coating with different temperatures was investigated.The mechanical of heat resistance of the coating was discussed.
