（3）To step（2）Three oxidations two of 6 ~ 10 mass parts chlorinated paraffin -70s or 3 ~ 5 mass parts are added in the material of acquisition
Antimony, 120 ~ 150 DEG C are warming up to, be stirred by ultrasonic 60 ~ 90 minutes；
（4）By step（3）The material of acquisition is put on moulding machine into mould, and in two stages, first stage temperature is 140 ~ 220 to Cheng Mo
DEG C, compressing time 2-3 minutes, second stage temperature is 110 ~ 130, compressing time 2 ~ 3 minutes, and fire prevention rubber is obtained after natural cooling
Glue.
Further, calculated by the butadiene-styrene rubber of 200 mass parts, zinc oxide is 2 ~ 3 mass parts in the material of addition, and carbon black is
10 ~ 12 mass parts, rubber softening oil are 8 ~ 10 mass parts, and vulcanizing agent is 6 ~ 8 mass parts, and chlorinated paraffin -70 is 8 ~ 10 mass parts,
Antimony oxide is 3 ~ 5 mass parts.
Further, calculated by the butadiene-styrene rubber of 200 mass parts, zinc oxide is 2 mass parts in the material of addition, carbon black 10
Mass parts, rubber softening oil are 9 mass parts, and vulcanizing agent is 8 mass parts, and chlorinated paraffin -70 is 8 mass parts, antimony oxide 3
Mass parts.
Further, the vulcanizing agent is one kind in sulphur, sulfur monochloride, urethanes and isocyanates.
Further, step（3）In be additionally added the pentaerythrites of 0.8 ~ 1.5 mass parts.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention provides a kind of preparation method of fire-resistant rubber, leads to
Cross and be added into chlorinated paraffin -70 or antimony oxide, so as to improve the anti-flammability of rubber, the high fire prevention of burning-point can be obtained
Rubber.The hardness of rubber, combustion-supporting property and glossiness are further improved by adding pentaerythrite.Step of the present invention is simple, institute
It is easily obtained with raw material and equipment, is advantageous to control cost and simplifies process, the fire-resistant rubber good flame resistance obtained, Neng Gouqi
To good flameproof effect.
