Abstract

The invention belongs to the field of rubber, and particularly relates to a rubber material with fire resistance. The fire-resistant rubber material disclosed by the invention comprises the following components in parts by weight: 50-180 parts of chloroprene rubber, 60-180 parts of ethylene propylene terpolymer, 5-12 parts of nano-zinc oxide, 3-5 parts of stearic acid, 10-25 parts of magnesium hydroxide N100, 1-6 parts of aluminum phosphate, 5-12 parts of magnesium silicate, 5-10 parts of sodium silicate, 5-18 parts of mica powder, 5-12 parts of silicon carbide, 1-5 parts of anti-aging agent, 1-10 parts of calcium carbonate, 2-7 parts of hydroxyl silicone oil, 2-6 parts of hydrogen silicon oil, 1-5 parts of white carbon black, 1-5 parts of simethicone, 1-5 parts of dibutyl phthalate, 1-5 parts of N-tertiary butyl-2-benzothiazole sulfonamide and 2-5 parts of 2-thiol based imidazoline. The rubber material has the beneficial effects that the fire-resistant rubber obtained by adopting the formula is good in fire resistance, can play a certain protecting role in a big fire, and can reduce the loss to people caused by the big fire.

Description

technical field [0001] The invention relates to a rubber material with fire resistance, 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, ...
