| 中文摘要: |
| 引入超速促进剂ZDBC并改变硫黄用量，制备出可低温（97 ℃）硫化的特种耐油胶管用氯丁橡胶（CR）复合材料，研究其物理性能、耐海水性能以及与法兰钢的粘合性能。结果表明：低温条件下制备的CR复合材料的拉伸强度为19.2 MPa，拉断伸长率为404%；室温条件下经过180 d人工海水浸泡后，CR复合材料的拉伸强度仅下降5.2%，质量变化率小于3%，耐海水性能优异；通过加入粘合剂RA-65/间苯二酚/新癸酸钴并用粘合体系并改变炭黑种类和用量配制的过渡胶与法兰钢的粘合强度为13.4 kN·m-1，达到国家标准要求。 |
| 英文摘要: |
| Chloroprene rubber（CR） composite for special oil resistant rubber hose which could be
vulcanized at low temperature（97 ℃） was prepared by introducing a overspeed accelerator ZDBC and adjusting
the sulfur dosage，and its physical properties，seawater resistance and adhesion with flange steel were studied.
The results showed that the tensile strength of the CR composite vulcanized at the low temperature was 19. 2
MPa，and the elongation at break reached 404%. After 180 days of artificial seawater immersion at room
temperature，the tensile strength of the CR composite only decreased by 5. 2%，and the weight change was
less than 3%，showing excellent seawater resistance. The transition compound prepared by adding adhesive
RA-65/resorcinol/cobalt neocaprate blend and adjusting the type and amount of carbon black had an
adhesive strength of 13. 4 kN·m-1 with flange steel，which met the requirements of the national standard. |
