POLYMER STRUCTURES BASED ON BUTADIENE-CO-ACRYLONITRILE AND CHLOROPRENE RUBBER FOR VULCANIZED SOLES USED IN THERMAL-RISK WORK ENVIRONMENTS

摘要

The invention relates to a polymer material used for manufacturing cured soles for work environments with thermal risk. According to the invention, the material is a mixture of 100 parts of chloroprene or butadiene-co-acrylonitrile rubber, up to 35 parts of mineral charges, 1...7 parts of chemically modified sodium montmorillonite, 10...13 parts of dioctyl phthalate, 1...2.5 parts of stearin, up to one part of an antioxidant, 0.5...1.5 parts of curing accelerators, 20...25% flame-proofing agents and 1...3 parts of technical grade sulphur, the parts being expressed by mass.
