Environment-friendly fireproof silicone rubber and preparation method thereof

Abstract

The invention discloses environment-friendly fireproof silicone rubber. The environment-friendly fireproof silicone rubber is prepared from raw materials in parts by weight as follows: 100-150 parts of high-temperature vulcanized silicone rubber, 1-5 parts of a vulcanizing agent, 7-13 parts of vinyl, 9-15 parts of white carbon black, 2-6 parts of magnetized powder, 7-15 parts of glass fiber, 0-10parts of pigment, 7-13 parts of wollastonite and 8-10 parts of mica powder. The environment-friendly fireproof silicone rubber is scientific and reasonable in structure and safe and convenient to use;high-temperature resistance is improved by white carbon black which is odorless and has good electrical insulating property; the glass fiber is generally used as a reinforcing material, an electricalinsulating material and a thermal insulating material in a composite; insulativity, high-temperature resistance, acid-base resistance, corrosion resistance and adhesion of the silicone rubber are improved by the wollastonite and the mica powder; vinyl has the advantages of flame retardance, high chemical resistance, high mechanical strength and good electrical insulating property; therefore, environment-friendliness and fireproofing of the silicone rubber are improved.

Description

technical field [0001] The invention relates to the technical field of environmentally friendly and fireproof silicone rubber, in particular to an environmentally friendly and fireproof silicone rubber and a preparation method thereof. Background technique [0002] Silicone rubber refers to the rubber whose main chain is composed of silicon and oxygen atoms alternately. There are usually two organic groups attached to the silicon atom. Ordinary silicone rubber is mainly composed of silicone chains containing methyl groups and a small amount of vinyl groups. The introduction of silicone rubber can improve the high and low temperature resistance of silicone rubber, the introduction of trifluoropropyl and cyano can improve the temperature resistance and oil resistance of silicone rubber, silicone rubber has good air permeability, and the oxygen transmission rate is the highest among synthetic polymers. is the highest. [0003] However, the fire resistance of silicone rubber cu...
