| Abstract: |
| 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. |
