Abstract
The invention belongs to the technical field of tires with special properties, and particularly relates to a snowfield tire sidewall rubber material composition and a preparation method. The snowfield tire sidewall rubber material composition is prepared from 20-30 parts of styrene-butadiene rubber, 40-60 parts of natural rubber, 20-30 parts of butadiene rubber, 30-50 parts of nanoscale sheet filler, 5-10 parts of white carbon black, 2-3 parts of zinc oxide, 4-10 parts of stearic acid, 4-5 parts of anti-ageing agent 4020, 2-4 parts of aromatic oil, 1.5-2.5 parts of sulfur, 0.5-1.2 parts of accelerant NS and 10-16 parts of tackifying resin. By means of the technical scheme, the ozone aging resistance and the flex crack resistance of rubber materials can be greatly improved without influencing the existing physical and mechanical properties of the rubber materials.
