以氯代乙酸乙烯酯为硫化点单体、二乙二醇单甲醚丙烯酸酯为第3单体,与丙烯酸丁酯和丙烯酸乙酯乳液共聚合成了丙烯酸酯共聚物,经混炼、硫化制得超耐寒丙烯酸酯橡胶,并分别对硫化胶的力学性能和热学性能进行了表征。结果表明,所得丙烯酸酯橡胶的拉伸强度达10 MPa,撕裂强度达23 kN/m,扯断伸长率300%左右,脆性温度低于-32℃,与目前耐寒级丙烯酸酯橡胶的脆性温度(-24℃)相比更低。 Using vinyl chloroacetate as the monomer of the vulcanization point and diethylene glycol monomethyl ether acrylate as the third monomer, acrylic ester copolymer was prepared by copolymerization with butyl acrylate and ethyl acrylate emulsion. Ultra-cold acrylate rubber was obtained, and the mechanical properties and thermal properties of vulcanizates were characterized. The results show that the tensile strength of the obtained acrylic rubber is 10 MPa, the tear strength is 23 kN / m, the elongation at break is about 300% and the brittleness temperature is lower than -32 ° C. Compared with the brittleness of the current cold-resistant acrylic rubber Lower temperature (-24 ° C).
