Abstract

The invention relates to a tread compound for a passenger tyre with high wet skid resistance and a preparation method thereof. The tread compound comprises, by weight, 13 to 16 parts of natural rubber, 61 to 83 parts of first solution-polymerized styrene butadiene rubber, 25 to 40 parts of second solution-polymerized styrene butadiene rubber, 10 to 20 parts of carbon black, 45 to 55 parts of white carbon black, 2 to 7 parts of a softener, 5 to 6 parts of an activator, 3 to 4 parts of an antioxidant, 1.8 to 2.2 parts of a wet skid resistance reinforcing agent, 4.5 to 5.5 parts of resin with high wet skid resistance, 7 to 9 parts of a coupling agent and 3 to 3.5 parts of a vulcanizing agent. The tyre prepared from the raw materials provided by the invention has wet skid resistance reaching grade A or above and is a high quality tyre with superhigh wet skid resistance.

Description

technical field [0001] The invention relates to a high-wet-grip passenger tire tread compound and a preparation method thereof, belonging to the field of automobile tires. Background technique [0002] With the rapid development of the automobile tire industry, customers have higher and higher requirements for the quality of passenger tires. The high quality of tires mainly includes tire safety, comfort, environmental protection and fuel economy, etc. These high qualities are reflected in tire performance: high wet grip, low rolling resistance, safe handling, etc. The market demands high-quality tires. Most of the grip performance of passenger tires on the market are in the B or C grade. In order to meet the higher demands of customers, we should not only be satisfied with the quality grades of B or C grades, but need to develop high-quality tires with grade A and above and ultra-high wet grip performance. Contents of the invention [0003] The invention provides a high...
