The invention relates to improved rubber for fire control. The improved rubber for fire control is prepared from the following raw materials in parts by weight: 30-50 parts of ethylene propylene rubber, 6-11 parts of polyvinyl silicone oil, 3-7 parts of sulphur powder, 7-10 parts of filling agent, 12-16 parts of trioctyl trimellitate, 6-11 parts of zinc oxide, 5-8 parts of high molecular weight fatty acid ester, 3-8 parts of carbon black and 3-7 parts of anti-aging agent. The improved rubber for fire control has the beneficial effects that the improved rubber for fire control has good acid and alkali resistance, stable chemical properties and good corrosion resistance and elasticity. |
