Abstract

The invention relates to fireproof rubber which comprises the following raw materials in part by weight: 100 to 150 parts of chloroprene rubber, 100 to 130 parts of natural rubber, 5 to 10 parts of zinc oxide, 2 to 5 parts of hydrogen silicon oil, 2 to 5 parts of stearic acid, 15 to 30 parts of magnesium hydroxide, 2 to 5 parts of an accelerant, 2 to 5 parts of a vulcanizing agent, 3 to 10 parts of aluminum phosphate, 3 to 10 parts of sodium silicate, 3 to 10 parts of silicon carbide, 1 to 5 parts of an anti-aging agent, 5 to 10 parts of calcium carbonate, 1 to 5 parts of hydroxyl silicone oil, 1 to 5 parts of dimethicone and 1 to 5 parts of dibutyl phthalate. The fireproof rubber has good fire resistance, can perform a certain protection effect in a big fire and can reduce loss which is caused by the big fire and is brought to people.

Description

technical field [0001] The invention relates to a fire-resistant rubber, which belongs to the field of rubber. Background technique [0002] Usually silicone rubber itself is not fire resistant. However, in the current fire accidents, wires and cables are not fire-resistant and easy to burn in case of fire. This field lacks a kind of fire-resistant silicone rubber, which is required to play a certain protective role in the fire, and can reduce the electricity brought to people in the fire. Loss, reduce the harm of electricity. Refractory rubber is made of chloroprene as the main raw material through homopolymerization or copolymerization of a small amount of other monomers. Such as rubber products with high tensile strength, excellent heat resistance, light resistance, aging resistance, and oil resistance are better than natural rubber, styrene-butadiene rubber, and butadiene rubber. It has strong flame resistance and excellent flame retardancy resistance, high chemical s...
