Abstract

The invention provides an anti-slip safety tire tread rubber and a preparation method thereof, and belongs to the technical field of tread rubbers. The anti-slip safety tire tread rubber can significantly improve the tread rubber anti-slip performance and meet the development requirements of the anti-slip safety tire by introducing graphene in the form of graphene composite glue in a tread rubbercompound formula. The anti-slip safety tire tread rubber is prepared from the following components in parts by weight: 100 parts of base rubber, 1 to 30 parts of graphene composite rubber, 40 to 55 parts of white carbon black, 25 to 45 parts of carbon black, 3 to 4.5 parts of silane coupling agents, 1 to 6 parts of active agents, 3 to 5 parts of antioxidant, 1 to 4 parts of tackifying resin, 5 to15 parts of plasticizer, 2 to 5 parts of vulcanization accelerator, and 1 to 3 parts of sulfur; the graphene composite rubber is prepared from graphene and rubber, wherein the graphene accounts for 5%to 20%.

Description

technical field [0001] The invention belongs to the technical field of tread rubber, in particular to an anti-wet skid safety tire tread rubber and a preparation method thereof. Background technique [0002] Anti-wet skid performance is an important index to measure the driving safety of tires, especially the driving safety in rainy days. For passenger cars, due to their high driving speeds, the wet skid resistance of tires is particularly important. In the new European regulations that were enforced in 2012, wet skid resistance has been included as one of the mandatory performances. In rainy days, when the car is driving on a wet road, due to the existence of water, there is a layer of water film between the tire tread and the road surface, which will greatly reduce the wet grip of the tire and affect the driving safety. Therefore, to improve the tire Anti-wet skid performance is of great significance to ensure the driving safety of vehicles. [0003] At present, major ti...
