Abstract
The invention provides a high-grip tire tread. The glue material of the high-grip tire tread comprises: 45 to 55% of high-styrene oil-extended styrene butadiene rubber, 30 to 40% of medium super abrasion furnace black, 1 to 5% of precipitated white carbon, 1 to 2% of chemical anti-ageing agent 6PPD, 0.5 to 1.5% of chemical anti-ageing agent BLE-65, 0.1 to 1% of physical anti-ageing agent microcrystallinewax, 0.5 to 2% of active agent ZNO, 0.5 to 2% of active agent SA, 1 to 3% of pinene resin, 5% to 15% of processing oil TDAE, 0.5 to 2% of vulcanizing agent S-325, 0.4 to 2% of accelerator NS and 0.1 to 1% of accelerator TMTD. The tire tread provided by the invention improves the grip performance of a tire, maintains the physical properties and wear resistance of the tire and improves the service performance of the tire.
Description
technical field [0001] The invention relates to the field of rubber products, in particular to a high-grip tire tread and a synthesis method thereof. Background technique [0002] For general tires, the lower the hardness, the higher the friction coefficient between the tread rubber and the ground, and the better the grip, but too low hardness will reduce the physical properties and wear resistance of the rubber compound, and seriously reduce the service life of the tire. Therefore, it is necessary to try our best to maintain the physical properties and wear resistance of the rubber while improving the grip. Contents of the invention [0003] The purpose of the present invention is to provide a high-grip tire tread with excellent grip performance, good physical properties and wear resistance. [0004] In order to achieve the above object, the technical solution provided by the present invention is a high-grip tire tread, in terms of weight percentage, the compound of the ...
