Abstract
Research was carried out into the development of a lite protective flame-resistant rubberized material with a set of protective properties against aggressive media (acids and alkalis), gaseous highly toxic substances (chlorine and ammonia), solvents, and oils. The effect of the composition of rubbers on their protective properties was studied. Rubbers with improved protective properties were prepared on the basis of chlorosulphonated polyethylene combined with chloroprene rubber. A substantial impact of the nature of cross bonds and the type of vulcanizing agent on resistance of rubbers to aggressive media was determined. A series of antipyrenes with a total content of 60 pts. wt. were developed. They ensure preparation of self-extinguishing rubber upon preservation of residual durability. A protective lite material with the low surface density and good protecting properties compared to analogues was prepared on the ground of the data obtained.
