CN104292560A - Stable fire-resistant rubber - Google Patents

Abstract

The invention discloses stable fire-resistant rubber, which is prepared from the following raw materials in parts by weight: 8-14 parts of chloroprene rubber, 6-10 parts of calcium carbonate, 2-6 parts of an anti-ageing agent, 1-5 parts of graphite powder, 2-5 parts of stearic acid, 1-5 parts of a vulcanizing agent, 4-8 parts of chlorosulfonated polyethylene, 4-9 parts of tert-phenol-formaldehyde resin, 1-3 parts of a plasticizer DOP, 1-5 parts of an antioxidant, 4-6 parts of a halogen-free flame retardant and 4-7 parts of dithiol. The sable fire-resistant rubber disclosed by the invention is stable in chemical property, has good self-extinguishing property, and can play a good role in the primary stage of a fire.

Description

A kind of stable flame resistance rubber

Technical field

The present invention relates to a kind of stable flame resistance rubber.

Background technology

In current fire failure, electric wire occurs not fire-resistant, meet fiery easy firing problem, this area lacks a kind of fire-resistant rubber, and requirement can play certain provide protection in big fire, can reduce the loss that in fire, electricity brings, and reduces the harm of electricity.Flame resistance rubber take chloroprene as main raw material, by homopolymerization or other monomer copolymerization on a small quantity.As tensile strength height rubber item, heat-resisting, fast light, ageing-resistant performance is excellent, oil resistance is all better than natural rubber, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber.Have stronger flame resistivity and excellent fire retardance, its chemical stability is higher, and water tolerance is good.In sum, this area is in the urgent need to working out flame resistance rubber, and requirement can play certain provide protection in big fire, can reduce the loss that in fire, electricity brings, and reduces the harm of electricity, and the physicals of rubber does not produce infringement simultaneously.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of stable flame resistance rubber, stable chemical nature, has good self-extinguishing simultaneously, can play good effect at Initial Stage of Fire.

For solving prior art problem, technical scheme provided by the invention is, a kind of stable flame resistance rubber, and it is made up of the raw material of following parts by weight:

Chloroprene rubber 8-14 part, calcium carbonate 6-10 part, anti-aging agent 2-6 part, Graphite Powder 99 1-5 part, stearic acid 2-5 part, vulcanizing agent 1-5 part, chlorosulfonated polyethylene 4-8 part, t-Butylphenol formaldehyde resin 4-9 part, plasticizer DOP 1-3 part, antioxidant 1-5 part, halogen-free flame retardants 4-6 part, two mercaptan 4-7 parts.

The invention has the beneficial effects as follows: stable flame resistance rubber of the present invention, stable chemical nature, has good self-extinguishing simultaneously, can play good effect at Initial Stage of Fire.
