【摘要】 研究了黏合剂中所使用的N 环己基 2 苯并噻唑基次磺酰胺(CZ),N,N 二环己基 2 苯并噻唑基次磺酰胺(DZ),二硫化二苯并噻唑(DM),N,N 间苯撑双马来酰亚胺(PDM)四种不同类型促进剂对黏合剂的影响,以及各促进剂不同用量对黏合剂的影响·实验结果表明,在本实验的黏合剂体系中,促进剂对EPDM橡胶与金属的黏接强度有提高作用,噻唑类促进剂的作用强于酰胺类,最佳促进剂为DM;噻唑类促进剂的最佳质量分数为0 5%,最大剪切强度为1 059MPa·更多还原

【Abstract】 Investigates the effect of the four accelerants contained in adhesives, i.e., N-cyclohexyl-2-benzothiazole sulphenamide(CZ), N,N-dicyclohexyl-2-benzothiazole sulphenamide(DZ), dibenzothiazole disulfide(DM) and N,N’-m-phenylene digmaleemide (PDM) on the adhesion of EPDM rubber to metals as well as the effects of their different dosages used on their adhesives. The results indicated that such accelerants contained in adhesives can increase adhesive strength of EPDM rubber to metals. Among them the thiazole accelerants are more effective than imides, but the best one is DM. It was found that the best mass fraction of thiazole is 0.5%, of which the max shear strength is 1.059MPa.更多还原
