Description
Art
The present invention relates to a kind of tread mix for being exclusively used in half steel ice and snow road special tyre, the sizing material is used for half steel winter
The production of snowfield special tyre.
Background technology
Ice and snow ground is up in the winter time easily skids when sailing for automobile, the security incidents such as vehicle rear-end collision, rollover occurs, therefore want
Automobile is asked to assemble the tire with extremely strong ice and snow road earth-grasping force in the winter time.Because tire tread directly contacts with road surface,
Therefore ice and snow road special tyre requires that tread mix must have extremely strong ice and snow ground grip, while sizing material will meet to take turns
The characteristic of tire tread sizing material：Anti-wear performance is excellent, rolling resistance is low.
The content of the invention
It is an object of the invention to provide the tread mix of half steel ice and snow road special tyre.
The purpose of the present invention is achieved through the following technical solutions：The tread mix of half steel ice and snow road special tyre,
It is characterized in that：It is formulated in mass ratio by following raw material：
The present invention technical principle be：Use based on the best polybutadiene rubber of resistance to low temperature, be used in combination in rubber system
The best natural rubber of combination property and a small amount of brombutyl, ensure that sizing material has excellent ice snow covered pavement under extremely low temperature
Face earth-catching property；The combination of rubber and hydrated SiO 2 can be strengthened using polymerisation in solution type Afpol.
By the use of hydrated SiO 2 as main reinforcing agent, and with a small amount of carbon black N375, and using a large amount of filling oil, ensure glue at low temperature
Expect soft texture, excellent with the earth-grasping force on ice and snow ground, the physical and mechanical properties and processing characteristics, reduction for improving sizing material match somebody with somebody square bar
Expect cost.
