1.涂胶 胶接件清除油污后,滴上胶液,装配。 2.固化 隔绝空气,常温20min初固,2～6h完全固化 3.一般采用水溶液聚合方法合成,原料甲基丙烯酸使用时蒸馏除去阻聚剂,过硫酸铵为引发剂,巯基乙酸为分子量调节剂。将计量的去离子水加到装有电动搅拌器、回流冷凝器、温度计和滴液漏斗的聚合反应器中,将巯基乙酸加入到反应器中与水混合均匀,开动搅拌并升高反应温度。将引发剂用计量的水配成适当的稀溶液置于聚合反应器上的滴液漏斗中,再将计量的甲基丙烯酸(MA)与计量的水配成一定比例的水溶液置于聚合反应器上的另一滴液漏斗中。当反应温度升至80℃左右时开始滴加引发剂溶液和甲基丙烯酸溶液,控制滴加速度使反应维持3～4h并使反应温度控制在85～90℃之间。聚合反应完毕,冷却反应物,取样测定产物的黏度、固含量,检查产物的阻垢率,合格后桶入库。聚合反应中,温度的控制、引发剂的用量、单体的浓度、分子量调节剂的用量以及单位时间内单体的浓度都将影响最终产物的分子量分布情况。因此整个聚合反应的操作必须严格按照工艺规定执行。
