| 摘 要： | 研究了吸酸剂氧化镁用量、填料配比和防老剂配比对共聚型氯醚橡胶(ECO)力学性能和老化性能的影响。结果表明,氧化镁用量为10 phr、白炭黑用量为30 phr、炭黑用量为10 phr、防老剂N,N-二丁基二硫代氨基甲酸镍(NBC)用量为2 phr时,胶料综合性能最好。拉伸强度为13.9 MPa,断裂伸长率为644%,100%定伸应力为2.6 MPa,硬度为71。125℃老化1 000 h后,拉伸强度保持率为100%,断裂伸长率保持率为26.4%。

| Abstract: | Effects of the loadings of acid acceptor （magnesium oxide）, the proportion of fillers and the proportion of anti-aging agents on the mechanical properties and thermo-oxidative aging properties of epiehlorohydrin rubber have been evaluated. The experimental results indicated that when the loadings of MgO, white carbon black, carbon black, and nickelous N,N-dibutyldithioearbamate were 10 phr, 30 phr, 10 phr and 2 phr respectively, the over-all properties of rubber were the best. The tensile strength of rubber composite was 13.9 MPa; the elongation at break was 644% ; the 100% modulus was 2.6 MPa and the hardness was 71. After aging at 125~C for 1 000 h, the percent retention of tensile strength was 100% and the percent retention of elongation at break was 26.4%. |
