FIELD: chemistry.
SUBSTANCE: invention relates to production of fire-resistant ceramic-forming electrically insulating silicon rubber. Ceramic-forming fire-resistant silicon rubber, obtained by vulcanisation using a peroxide, addition or polycondensation mechanism, including a rubber mixture (based on silicon rubber, reinforcing filler, anti-texturing additive), a cross-linking agent, ceramic-forming filler and a catalyst, which includes 1-10 pts.wt ceramic-forming filler, a mixture of compounds (metal concentration, pts.wt): platinum (1·10-4-1.5·10-3), palladium (0-0.1), cobalt (0-0.1), manganese (0-0.1), cerium (0-2), iron (0-1.5), zirconium (0-0.1), samarium (0-1), silicon rubber (80-95 pts.wt).
EFFECT: after exposure to a flame, the rubber is characterised by very low content of hazardous substances in combustion products, does not form an aggressive medium, forms a high-strength, dense hydrophobic ceramic-like layer and can be used to make electrical cables, sealing materials, protective coatings, joints and other articles for similar purposes.
