Embodiment Construction

[0023] Below in conjunction with embodiment the present invention will be further described:

[0024] The raw material components and content of the present invention can be prepared according to existing conventional techniques, and the concrete steps are:

[0025] The first stage of mixing: add natural rubber and butadiene rubber to the internal mixer GK400, press the bolt for 20 seconds, mix carbon black, white carbon black, zinc oxide, anti-aging agent 4020, anti-aging agent RD, silane coupling agent, Add protective wax to internal mixer GK400 at the same time, press the bolt for 30 seconds, lift the bolt, press the bolt to 125°C and lift the bolt, press the bolt again to 145°C and keep for 30 seconds, then discharge the glue, and thin pass twice on the open mill to remove the sheet.

[0026] The second stage of mixing: Add a section of mixed rubber, press the bolt for 35 seconds, lift the bolt and then press the bolt for 35 seconds, lift the bolt and press the bolt to 145...

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a tire tread rubber composition with low rolling resistance. Background technique [0002] As we all know, with the continuous development of the automobile industry and the increasing scarcity of world oil resources, how to reduce the rolling resistance of tires has become a hot research topic in the tire industry. The rolling resistance of tires is mainly determined by the compound formula and tire structure, among which the tread compound formula is the main influencing factor. The hysteresis loss of the tread rubber directly affects the rolling resistance of the tire at 60°C. All components in a tread compound formulation contribute to hysteresis loss. Proper selection of polybutadiene rubber, integrated rubber, trans polyisoprene rubber, etc. in the tread formula can effectively reduce the hysteresis loss of the rubber compound; proper selection of white carbon black and si...
