摘要/Abstract

摘要： 以二甲苯为溶剂，过氧化苯甲酰(BPO)为引发剂，采用乙烯基三乙氧基硅烷(VTES)和苯乙烯(St)为接枝单体，自由基溶液聚合法改性氯化聚丙烯(CPP)，制得接枝共聚胶黏剂。并考察了聚合单体用量及配比、溶剂用量、引发剂用量、反应温度和反应时间对树脂胶黏性能的影响。得到的最佳反应条件为：溶剂与CPP的质量比m(二甲苯)∶m(CPP)=2.5∶1，聚合原料配比m(CPP)∶m (VTES)∶m (St)∶m (BPO) =100∶2.4∶0.6∶0.2，反应温度95 ℃，反应时间3 h。在此条件下制备的共聚物粘接聚丙烯材料和钢的剪切强度分别达3.4 MPa和7.7 MPa。

Abstract: A series of adhesives were prepared from chlorinated polypropylene (CPP)，vinyl triethoxy silane (VTES) and styrene (St) by solution polymerization，using benezoperoxide (BPO) as initiator and xylene as solvent. The influence factors，such as solution quantity，initiator concentration，monomers quantity and ratio，reaction temperature and reaction time were investigated. The optimum reaction conditions were determined，i.e.，mass ratio of solvent and CPP m(xylene)∶m(CPP)=2.5∶1，material mass ratio of polymerization system m(CPP)∶m (VTES)∶m (St)∶m (BPO) =100∶2.4∶0.6∶0.2，reaction temperature 95℃ and reaction time 3h. Under these conditions the adhesive showed good adhesive property and the shear strengths of felted polypropylene and adhered steel materialreached 3.4MPa and 7.7Mpa respectively.
