Abstract

The invention belongs to the field of rubber tire manufacturing, and relates to tire tread rubber with ultra-low rolling resistance and ultra-high wet grapping performance and a preparation method thereof and a tire. The tire tread rubber with ultra-low rolling resistance and ultra-high wet grapping performance is prepared by smelting the following raw materials in parts by weight: 50.0-90.0 parts of solution-polymerized butadiene-styrene rubber I, 20.0-40.0 parts of solution-polymerized butadiene-styrene rubber II, 10.0-40.0 parts of solution-polymerized butadiene-styrene rubber III, 50.0-120.0 parts of highly dispersed white carbon black, 3.0-8.0 parts of a white carbon black dispersing agent, 5.0-30.0 parts of aromatic hydrocarbon oil, 8.0-15.0 parts of a silane coupling agent I, 2.0-8.0 parts of a silane coupling agent II, 6.0-18.0 parts of road grapping resin and 0.2-1.6 parts of an accelerant TOT-N. By using the tire tread rubber formula with ultra-low rolling resistance and ultra-high wet grapping performance, the rolling resistance of the tire can reach below 6.5 (A grade: RRC is smaller than or equal to 6.5), the wet grapping performance can reach over 1.55 (A grade: G is greater than or equal to 1.55), and meanwhile, various physical and mechanical properties of the rubber and the high-speed durability of the tire meet the normal operating requirements.

Description

technical field [0001] The invention belongs to the field of rubber tire manufacturing, and relates to a tire tread compound with ultra-low rolling resistance and ultra-high wet grip performance, a preparation method thereof and a tire. Background technique [0002] The development of the automobile industry promotes the continuous innovation and progress of the tire industry. The rolling resistance and wet grip performance of tires, related to the environmental protection and safety performance of tires, have been included in the labeling laws of tires by many countries. For example, Japan began to implement a voluntary tire labeling system in 2010; South Korea promulgated tire labeling regulations on November 14, 2011; the European Union implemented mandatory tire labeling regulations on November 1, 2012. China's tire labeling system is also currently under preparation. [0003] The energy consumption caused by tire rolling resistance accounts for 15% of fuel consumption...
