摘　　要：以氟乙烯-乙烯基醚聚合物(FEVE)树脂为基体,添加三氧化二铝、二氧化硅、三氧化二铬等填料,三聚体755K固化剂及其他助剂,研制出一种双组分常温固化涂料。通过L9(43)正交试验和极差分析得出最佳配方。实验结果表明:当FEVE树脂的用量为10 g、755K的用量为2 g、三氧化二铬的用量为0.2 g、二氧化硅的用量为1.0 g、三氧化二铝的用量为1.0 g时,涂层综合性能最佳。涂层的附着力为0级,铅笔硬度为5H,耐磨性为在3.3 kg负荷作用下与钢轮对磨1 000圈,弦长为4.98 mm。A 2K room - temperature curable fluorocarbon coatings with good abrasion resistant performance is developed, which is based on fluoroethylene vinyl - ether copolymer （FEVE） as the binder, mixed with chromium oxide, TDI curing agent and other additives. The formula was optimized by use of L9 （4^3） orthogonal design and range analysis. The results show that when the dosage of fluoroethylene vinyl - ether copolymer is 10 g, and 2 g of 755K, 0.2 g of chromium oxide, 1.0 g of silica, 1.0 g of alumina, comprehensive properties of the coating film are the best. under 3.3 kg of loading, the trace length is 4.98 mm fro abrasion resistance by 1 000 cycles, and 5H for hardness, 0 for adhesion.
