FIELD: rubber industry.
SUBSTANCE: dispersing additive for rubber compounds, which may be used in tire manufacture, is based on zinc and calcium salts of stearic acid and tallow oil fatty acids and further contains calcium salts of tallow oil resin acids in amounts from 20 to 60%, while weight ratio of stearic acid zinc and calcium salts to zinc and calcium salts of tallow oil fatty and resin acids ranges between 1:1 and 2:1. Rubber compound also contains of mono-, di-, and triethanolamine in amounts of 0.1 to 3% on the weight organic acid salts.
EFFECT: enabled preparation of resin compound additive with controlled softening temperature.
