Description
Technical field
The present invention relates to rubber processing application field, and in particular, to it is a kind of prepare vulcanization rubber method and by this
Application of the vulcanization rubber, foregoing vulcanization rubber that method is prepared in tire is prepared.
Background technology
With world energy sources crisis and the aggravation of environmental pollution, various countries are to energy saving and environmentally friendly increasingly pay attention to.In order to reduce
The consumption of fuel oil and the discharge of greenhouse gases, auto industry also develop towards energy saving and environmentally friendly direction.
2009, European Union promulgated two new legislations for being related to tire, it is desirable to farthest improves tire safety, subtracts
Few oil consumption, reduce noise.This performance to tire proposes the requirement of higher, it is desirable to which tire is ensureing high distance travelled (tyre surface
It is wear-resisting) on the premise of road pavement grasp property it is good, the wet-sliding resistant performance especially on rainy day wet-skid road surface and ice and snow road
It is good.And high-performance tire then requires low-rolling-resistance, good wet-sliding resistant performance and excellent wear-resisting property.
At the end of the 20th century, Michelin proposes the concept of " green tire ", refers to being matched somebody with somebody with white carbon alternative tires tread rubber
Carbon black in side declines tire drag, oil consumption is reduced, and reaches motor vehicle emission reduction and energy-saving and emission-reduction as reinforcing agent
Purpose.

The dispersiveness of white carbon filler gum through coupling agent Si69 heat treatments improves, and vulcanizes the 300% stress at definite elongation increase of rubber, draws
Disconnected elongation reduces, and wet-sliding resistant performance improves, and rolling resistance and dynamic heat build up reduce, wear-resisting property and anti-cut poor-performing.
《Tire industry》(2007,1:25-30) inquired into silica/carbon black and with comparing emulsion polymerized styrene butadiene rubber
The influence of ESBR1721 and solution polymerized butadiene styrene rubber SSBR Y837V2 passenger car tire treads colloidality energy.The result shows that with hard charcoal
Black/carbon black and with than increase, the tan δ values and rolling loss during ESBR1721 and SSBR Y837V2 60 DEG C of rubber of vulcanization be linear
Decline, the tan δ values and lateral factor linear increment, wear-resisting property at 0 DEG C are declined slightly.
White carbon of the green tire production because largely using high structure in formula, white carbon are not easy to disperse when being kneaded, and
Volume can improve the hardness of sizing material when coordinating, heat is larger during mixing, so process implementing and difficult processing in tire production process
Degree is very big.
