一种汽车线束保护套
摘要：
本发明公开了一种汽车线束保护套，其是由以下重量份数的组分组成：三元乙丙橡胶112‑120份、异戊橡胶25‑32份、丙烯腈‑苯乙烯共聚物25‑32份、噻吩5‑7份、N，N'‑(4,4'‑亚甲基二苯基)双马来酰亚胺12‑19份、聚酰胺5‑9份、聚碳酸酯4‑8份、邻苯二甲酸二辛脂8‑16份、月桂醇聚氧乙烯醚9‑16份、硬脂酸钡10‑15份、柔韧性助剂4‑8份、耐磨助剂7‑11份。本发明的线束保护套材料力学性能较佳，其断裂伸长率最高可达87.6％,拉伸强度可达18.4MPa,具有较好的弹性及韧性，同时其体积电阻率得到大大提高，具有良好的绝缘性。
摘要（英）：

The invention discloses an automobile wire harness protection sleeve. The automobile wire harness protection sleeve is prepared from the following components in parts by weight: 112-120 parts of ethylene-propylene-diene monomer, 25-32 parts of isoprene rubber, 25-32 parts of acrylonitrile-styrene copolymer, 5-7 parts of thiophene, 12-19 parts of N,N'-(4,4'-methylenediphenyl)dimaleimide, 5-9 partsof polyamide, 4-8 parts of polycarbonate, 8-16 parts of dioctyl phthalate, 9-16 parts of polyoxyethylene lauryl ether, 10-15 parts of barium stearate, 4-8 parts of flexibility auxiliary and 7-11 partsof a wear resistant auxiliary. A wire harness protection sleeve material is excellent in mechanical performance, the elongation at break of the wire harness protection sleeve material can be up to 87.6%, the tensile strength can reach 18.4 MPa, the wire harness protection sleeve material has good elasticity and tenacity, meanwhile, the volume resistivity of the wire harness protection sleeve material is greatly improved, and the wire harness protection sleeve material has good insulativity.
