摘要
以丙烯酸丁酯(BA)、丙烯酸乙酯(EA)为主单体,β-丙烯酰氧基丙酸甲氧基乙酯(-βCE-MOA)为低温单体,甲基丙烯酸缩水甘油酯(GMA)为硫化点单体,邻苯二甲酸二辛酯(DOP)、癸二酸二丁酯(DBS)分别作为充油单体,采用乳液聚合法制备了环氧充油型丙烯酸酯橡胶(ACM)。并用IR、1H-NMR表征了共聚物的结构;DMTA测定共聚物的玻璃化转变温度(Tg);填充邻苯二甲酸二辛酯(DOP)的丙烯酸酯橡胶的最低脆性温度达-38℃;填充癸二酸二丁酯(DBS)的丙烯酸酯橡胶的最低脆性温度达-42℃。同时考察了不同聚合工艺以及充油单体含量对橡胶性能的影响。
In this paper , epoxy oil-extended ACM was synthesized by means of emulsion copolymerization using BA, EA, β-CEMOA as comonomers , GMA as crosslinking monomer, DOP and DBS as oil-extended comonomer. The structure of the title copolymer was characterized by IR, ^1H-NMR; Its Tg was measured by DMTA. The minimum brittleness temperature of the ACM filled with DOP was -38℃ and which filled with DBS was -42℃. And the effect of different polymerization techniques and feeding amount of DOP on physical properties of epoxy oil-extended ACM were investigated.
