摘要
本课题根据涂附磨具对胶粘剂的性能要求 ,合成了以甲基丙烯酸甲酯 丙烯酸丁醋MMA BA ,为主单体 ,N -羟甲基丙烯酰胺 (N -MA)为功能单体的聚丙烯酸酯交联型乳胶。通过测试乳胶的性能指标 ,分析共聚体系中各原料组成及用量对乳胶的机械强度、成膜性、耐水性、耐磨性的影响 ,得出了合适的单体组合及配比 (乳化剂用量为 2 6wt % ,N -MA的合适用量为 2 9～ 3 5wt % )。将研制的乳胶用于涂附磨具产品试验 ,结果显示 ,控制好固化工艺 ,可满足不同柔软性涂附磨具的需求。
This paper focused on the properties of cross linkable polyacrylate latex adhesives with MMA/BA (methyl methacrylate/buthl acrylate) as the main monomers, N MA(N methylo acrylamidy)as the functional monomer respectively to meet the requirements of the coated abrasives products fabrication The effects of the constituents and their concentration in the copolymerized emulsion upon its mechanical strength, film forming properties, abrasion resistance and water resistance have been examined The proper addition ratio is 2 9～3 5(wt)% for N MA and 2 6(wt)% for emulphor It is found that the copolymerized emulsion can meet the pliability requirements of different kinds of the coated abrasives products
