【摘要】 采用溶液聚合法,以甲基丙烯酸甲酯、丙烯酸、苯乙烯和丙烯酸丁酯为单体,正丁醇为溶剂,BPO为引发剂,制备了水性丙烯酸树脂。通过对比不同配方树脂对应漆液的粘度、凝胶化时间和水溶性,以及固化后漆膜的硬度、韧性和附着力等因素,确定了树脂的最佳配方。分析了引发剂、中和剂和助剂用量对硅钢片漆性能的影响。结果表明:制备的硅钢片漆漆膜外观光滑,硬度高,具有较好的附着力和韧性。更多还原

【Abstract】 A water-soluble acrylic resin was prepared by solution polymerization using methyl methacrylate(MMA),acrylic acid(AA),styrene(SM) and butyl acrylate(BA) as monomer,butanol as solvent and BPO as initiator.The optimum formula was determined by comparing the viscosity,gel time and water solubility of different formula of resin and the hardness,toughness and adhesion of corresponding cured film.The effects of initiator,neutralizer and additive content on the properties of the lamination coating were investigated.The results show that the prepared film has smooth appearance,high hardness,excellent adhesion and toughness.更多还原
