摘 要: 选用115、2015、NX-2045和2041四种胺类固化剂,并对固化后的环氧树脂涂膜进行比较试验,结果表明:使用NX-2045固化剂后涂膜的干燥速度、力学性能、耐盐雾性能都较优;但附着力和涂膜耐酸、耐碱能力仍有待提高。通过添加适量的(0.4%质量份)含氨基硅烷偶联剂A-1120,附着力与不加相比,从1级提高到0级,涂膜耐酸和耐碱能力都有提高。 Four amine curing agents were chosen for crosslink of epoxy resin and then the cured epoxy coating properties were tested. The drying rate, mechanical properties, resistance to 5% NaCl solution of the coatings were excellent, but the adhesive force to the metal substrate, resistance to acid and alkali were not very good. A kind of amide silane coupling agent was used to improve the properties of the epoxy coatings. The adhesive force was enhanced and the resistance to acid and alkali was also improved when the coupling agent amount was 0. 4%.
