Abstract

The invention belongs to the field of rubber tire manufacturing and relates to a rubber composition for a tire and capable of significantly reducing the rolling resistance of the tire without reducingthe wear resistance of the tire, and the rubber composition is particularly suitable for tread manufacture of a low rolling resistance tire. The rubber composition is prepared from the components inparts by weight: 50-90 parts of at least one rubber component selected from natural rubber, polyisoprene rubber, polybutadiene rubber and styrene-butadiene copolymer rubber, 5-30 parts of high cis polybutadiene composite rubber, 5-20 parts of trans polyoctene rubber, 30-70 parts of silica and 5-15 parts of carbon black. When the rubber composition is adopted for manufacturing the tire, the tire rolling resistance is significantly reduced while the wear resistance of the tire is not reduced, and the rubber composition is particularly suitable for tread manufacture of the low rolling resistancetire. The physical and mechanical properties of rubber materials and the high speed and durability of the tire can meet the requirements of normal use.

Description

technical field [0001] The invention belongs to the field of rubber tire manufacturing, and relates to a rubber composition for tires that can significantly reduce the rolling resistance of the tire without reducing the wear resistance of the tire, and is particularly suitable for manufacturing treads of tires with low rolling resistance. Background technique [0002] With the increasingly tense global energy supply and the deteriorating environment, the energy saving and emission reduction of automobiles is imminent. According to calculations, if the tire rolling resistance is reduced by 20%, the carbon dioxide emission per kilometer can be reduced by 4 grams, and each car can save 23 liters of fuel per year. [0003] As an important performance index of tires, there is a "devil's triangle" relationship among rolling resistance, wear resistance and wet skid resistance: under normal circumstances, these three properties tend to ebb and flow, and adjusting any of the three pr...
