摘　　要：以环氧乳液E-Pos 1011W55和胺固化剂Q-RIT 1071制备了一款适用于拉链头的双组分水性涂料。实验表明,在环氧与活泼氢的物质的量比控制在1.14-1.26,加入有机硅氧烷类附着力促进剂,以丙二醇二乙酸酯(PGDA)作为成膜助剂的条件下,所制涂膜光亮平整,其附着力、铅笔硬度、耐冲击性、耐磨性、耐水性、耐碱性和耐水洗性均满足实际应用要求。A two-component waterborne paint suitable for zipper heads was prepared based on epoxy emulsion E-Pos 1011W55 and amine curing agent Q-RIT 1071.The test results showed that the coating obtained at a molar ratio of 1.14-1.26 for epoxy groups to active hydrogens with organosiloxane as adhesion promoter and propylene glycol diacetate(PGDA)as coalescing agent is bright and smooth,and its adhesion strength,pencil hardness,impact resistance,abrasion resistance,water resistance,alkali resistance,and washing durability meet the requirements of practical application.
