利用静态浸泡法通过绘制增重率-时间曲线及采用红外光谱研究高温条件下环氧粉末涂层耐介质(水、碱)渗透的能力，探讨了高温(100℃～120℃)与低温(T<100℃)下该涂层中的介质传输行为.结果表明：在环境温度高于玻璃化转变温度时，涂层抗介质渗透能力差；在环境温度小于玻璃化转变温度时，涂层抗介质渗透能力强.介质温度在100℃～120℃范围内，环氧涂层与其在低温条件下同样具有良好的耐碱性.
Epoxy powder coating resistance to corrosion medium in high temperature solution is investigated using static immersion method and infrared spectroscopy, analyzed medium transport behavior between 100℃ to 120℃ and between 100℃. Experience results show: (1)When the medium temperture is higher than Tg, epoxy powder coating resistance to corrosion medium is worse. When the medium temperature is lower than Tg, Epoxy powder coating resistance to corrosion medium is better. (2)Epoxy powder coatings in high temperature solution(100℃ ≤ T≤ 120℃ )have same good alkali- resistance as that in low temperature solution( T<100℃ ).
