FIELD: rubber industry.
SUBSTANCE: invention relates to the rubber industry, namely to the development of frost-resistant elastomeric materials that can be used for the manufacture of various types of technical rubbers, in particular frost-resistant rubbers. Frost-resistant rubber based on natural rubber is offered, including natural rubber, technical sulfur, zinc whitewash (zinc oxide), polymerized 2,2,4-trimethyl-1,2-dihydroquinoline (acetonanyl P), technical stearin, plasticizer. The distinctive features of the claimed invention are that as a plasticizer it contains a compound of vaseline oil and an extract of oil from the fruits of Sosnovsky’s hogweed (1:1 by volume), additionally contains 2-mercaptobenztiazole and tetramethylthiuram disulfide.
EFFECT: frost-resistant rubber based on natural rubber according to the invention has a low residual deformation, high frost resistance (from minus 65°C to minus 70°C), high specific tensile strength.
