以环氧树脂(EP)改性有机硅树脂作为基体树脂,通过加入锌铬黄和铁红等填料,配制成一种耐高温、防腐蚀性的粘接底层;以有机硅树脂为基体树脂,通过加入锐钛型钛白粉和纳米SiO2,配制成具有一定遮盖力和耐高温性能的粘接面层。对涂敷底层和面层的马口铁试片进行耐高温性能和耐腐蚀性能测试,并采用金相显微镜和扫描探针分别对底层、面层和(含底层/面层的)双层粘接涂层的微观结构进行表征。结果表明:当底层中的颜基比为1.4∶1时,粘接涂层可耐400℃高温,在各种介质中浸泡72h后,粘接涂层表面没有开裂现象;当底层中的颜基比为1.7∶1时,其填料在树脂中分散得比较均匀,两者间的结合效果较好,该粘接涂层可耐400℃高温,但耐腐蚀性能相对较差。
Epoxy resin (EP) modified silicone resin as matrix resin, by adding zinc chrome yellow and iron red filler, formulated into a high temperature, anti-corrosion adhesive primer; silicone resin as the matrix resin, by Join anatase titanium dioxide and nano-SiO2, formulated with a certain hiding power and high temperature performance of the adhesive surface layer. The test of the high temperature resistance and the corrosion resistance of the tinplate coated with the bottom layer and the surface layer was carried out. The surface of the bottom layer, the surface layer and the double layer (including the bottom layer / the surface layer) were coated with the metallographic microscope and the scanning probe The microstructure of the layer was characterized. The results show that when the ratio of base to base in the base is 1.4:1, the adhesive coating can resist the high temperature of 400 ℃. After soaking in various media for 72 hours, the surface of the adhesive coating is not cracked. When the base The ratio of 1.7: 1, the filler dispersed in the resin is more uniform, the combination between the two better, the adhesive coating can withstand high temperatures 400 ℃, but the corrosion resistance is relatively poor.
