【摘要】 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。更多还原

【Abstract】 A polybasic graft copolymerization of acrylic acid (AA) and N (hydroxymethyl) acrylamide (NAM) as functional monomers with methyl 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.更多还原
