Step 2: triallyl isocyanurate and dichloro-benzenes are mixed, using hydrosilylation, obtain multifunctional assistant
TS；
Step 3: being put into vacuum kneading machine for the resulting modified silicon rubber of step 1 and medium density polyethylene resin and be kneaded,
Obtain mixture B；
Step 4: vulcanizing agent, vulcanization accelerator, anti-aging agent, remaining reaction adjuvant are placed on the resulting mixing of step 3
Expect among B；
Step 5: it is squeezed the resulting finished product mixture of step 4 to obtain rubber cable attachment by grinding tool extruder.
