FIELD: inorganic chemistry.
SUBSTANCE: invention refers to tyre and rubber industry. Milled rubber scrap is mixed with hydrocarbon fraction and heat-treated at 150-250°C during 0.5-24 h. Fuel oil with initial boiling 350°C and aniline point 80°C and more is used as hydrocarbon fraction. Mixture ratio, mass.%: milled rubber scrap - 30-90, specified hydrocarbon fraction - 10-70. Technical result lies in widening of plasticizers raw materials base accompanying with low content of aromatic hydrocarbons and improvement of physical-mechanical properties of rubber compound based vulcanizers.
EFFECT: widening of plasticizers raw materials base accompanying with low content of aromatic hydrocarbons; improvement of physical-mechanical properties of rubber compound based vulcanizers.
