Abstract

The invention discloses a low-temperature-resistant wet-skid-resistant tire tread and a preparation method thereof, and belongs to the technical field of tire tread rubber compositions, the tire treadcomprises a low-temperature-resistant wet-skid-resistant tire tread rubber composition, and the tire tread rubber composition comprises 10-30 parts of polybutadiene rubber, 40-70 parts of medium-lowstyrene low-Tg SSBR, 10-30 parts of SSBR with high styrene and high Tg, 5-20 parts of anti-slippery resin, 80-120 parts of white carbon black, 5-15 parts of a silane coupling agent and 20-60 parts ofenvironment-friendly oil. The product is applied to tires, solves the problem that the existing tread rubber composition cannot well improve the wet skid resistance and the low temperature resistance,and has the characteristics that the low temperature resistance, the wet skid resistance and the rolling resistance of the tires can be improved at the same time, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of tire tread rubber compositions, in particular to a tire tread with low temperature resistance and wet skid resistance and a preparation method thereof. Background technique [0002] The general theory holds that the higher the glass transition temperature (Tg) of the tread rubber, the greater the hysteresis loss around 0°C (tanδ@0°C), the higher the number of silica fillings, and the higher the styrene content of the SSBR used, the higher the The better the wet skid resistance of the obtained tire. However, the low temperature resistance of the rubber compound requires its low-temperature storage modulus (such as E'@-20°C) to be low, and the Tg and styrene content of the compound should also be low, so as to avoid the compound becoming hard and brittle at low temperatures To ensure the low-temperature grip of the tire. It can be seen that for the common rubber combination with a single glass transition ...
