无三苯CR/SBS/MMA/BA自交联鞋用胶粘剂的研制

采用复合引发剂，以N-羟甲基丙烯酰胺（NAM）及丙烯酸（AA）为功能单体，与CR、苯乙烯-丁二烯嵌段共聚物（SBS）、甲基丙烯酸甲酯（MMA）和丙烯酸丁酯（BA）进行多元共混接枝共聚，再配以混合型增粘树脂，研制出不含苯、甲苯和二甲苯（简称三苯）自交联环保型鞋用胶粘剂。探讨了SBS用量、MMA/BA配比、功能单体NAM及AA用量对胶粘剂粘合性能的影响。结果表明，CR/SBS/MMA/BA/AA/NAM自交联型接枝胶粘剂对非极性鞋材的粘合性能明显优于CR/MMA/BA三元接枝胶和CR/SBS/MMA/BA四元接枝胶。;A polybasic graft copolymerization of acrylic acid （AA）and N-（hydroxymethy l）acrylamide（NAM）as functional monomers with methy l methacrylate（MMA），butyl acrylate（BA）on CR and SBS was carried out in an aromatic hydrocarbon-free solvent by using composite initiator.An aromatic hydrocarbon-free solvent and self-crosslinking adhesive for shoes was prepared with the above copolymer by adding a tackifying resin.The influence of the addition levels of SBS，NAM and AA，and the MMA/BA ratio on the adhesive properties was investigated.The results showed that the properties of the above said adhesive bonded to non-polar shoe materials were much better than those of both CR/MMA/BA terbasic graft copolymer adhesive and CR/SBS/MMA/BA tetrabasic graft copolymer adhesive
