Preparation method of dual-crosslinking acrylic emulsion for soft porcelain
The invention discloses a dual-crosslinking acrylic emulsion for soft porcelain and a preparation method thereof, and the preparation method comprises the following steps: weighing an acrylate monomer, a methacrylic acid monomer, an acrylic acid monomer and an acrylic acid functional monomer containing ketone carbonyl by adopting a seed emulsion polymerization mode, and uniformly mixing and stirring to prepare a mixed monomer for later use; the preparation method comprises the following steps: adding an emulsifier, sodium bicarbonate, deionized water and 30-50% of an initiator into a three-necked flask, dropwise adding 5-15% of a mixed monomer into the flask, and stabilizing for 5-20 minutes to obtain a seed emulsion; dropwise adding the residual mixed monomer and the initiator within 2-4 hours, heating, curing, cooling, discharging and the like to obtain a carboxyl acrylate emulsion; the ketone-containing carbonyl acrylic emulsion is mixed with a filler, a hydrazide-based cross-linking agent and a carboxyl cross-linking agent, under the action of an acid catalyst, high-temperature baking is performed to prepare the double-cross-linking type soft porcelain, and the soft porcelain has excellent flexibility, strong adhesive force with a base material and excellent weather resistance.
本发明公开了一种用于软瓷的双重交联型丙烯酸乳液及其制备方法，该制备方法是采用种子乳液聚合方式，称取丙烯酸酯单体、甲基丙烯酸单体、丙烯酸单体、含酮羰基的丙烯酸功能单体，混合搅拌均匀制备混合单体备用；将乳化剂、碳酸氢钠、去离子水和30~50%的引发剂置于三颈烧瓶中，取5~15%的混合单体滴加至烧瓶中，稳定5~20 min后，得到种子乳液；将剩余的混合单体和引发剂在2~4 h内滴加完成，经升温、熟化、降温后出料等到羧基型丙烯酸酯乳液；将上述含酮羰基丙烯酸乳液与填料、酰肼基交联剂和羧基交联剂混合，在酸性催化剂的作用下，高温烘烤制备双重交联型软瓷，该软瓷具有优良的柔韧性、与基材的强附着力及优异的耐候性能。
