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。
(BA), ethyl acrylate (EA) as the main monomer, β-acryloyloxypropionic acid methoxyethyl ester (-βCE-MOA) as the low temperature monomer, glycidyl methacrylate GMA) as the monomer of the curing point, dioctyl phthalate (DOP), dibutyl sebacate (DBS) as the oil-filled monomer, respectively, by emulsion polymerization epoxy acrylate type rubber ACM). The structure of the copolymer was characterized by IR and 1H-NMR. The glass transition temperature (Tg) of the copolymer was measured by DMTA. The minimum brittleness temperature of the acrylate rubber filled with dioctyl phthalate (DOP) was -38 ℃. Acrylate rubber filled with dibutyl sebacate (DBS) had a minimum brittleness temperature of -42 ° C. The effects of different polymerization processes and oil-filled monomers on rubber properties were also investigated.
