Abstract
The invention relates to tread rubber for an engineering tire. Under synergistic effect of components in the tread rubber, a rubber material has the advantages of high wear resistance, high fatigue resistance, aging resistance, high tensile strength, high elasticity and high strength and toughness. The tread rubber can enable the tire to effectively buffer impact and swinging during driving, so as to prevent laceration and puncture of a cord layer.
Description
Technical field
The invention belongs to tread rubber technical field, be specifically related to a kind of engineering tire tread rubber.
Background technology
Because natural rubber has best bond properties, and synthetic rubber has outstanding abrasion resistance, thus all-steel radial tyre tread rubber generally adopt natural rubber and synthetic rubber and rubber system.
Off-the-road tyre travel speed is low, load is large, haul distance is short, turning is frequent, its tread rubber general requirement cut resistant, resistance to puncture, anti-collapse use up block, abrasion performance, good springiness, hardness high, be out of shape little, heat-dissipating is low.Based on the over-all properties that natural rubber is good, although the prices of raw and semifnished materials are high, traditional off-the-road tyre tread rubber composition majority still adopts All Pure Nature rubber, or with styrene-butadiene rubber(SBR) in 70/30 ratio and use.In fact, theoretical and test all shows, natural rubber for improving the abrasion performance of tread mix, cut resistant, resistance to puncture, anti-collapsing use up block performance and reduce the aspects such as distortion, contribute not remarkable, its advantage is mainly good processing characteristics and lower hysteresis loss, and these characteristics all by equipment and processing and manufacturing technology and reasonably Design of Tire Structure made up.Although adding of styrene-butadiene rubber(SBR) can provide good belt cutting-resisting property for tread rubber, its heat-dissipating is higher, and speed of response is slow, and wear resisting property is slightly poor.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of engineering tire tread rubber.By being optimized the raw material of tire tread glue and ratio and adjusting, meet tire tread cut resistant, anti-collapse use up block while, improve its wear resisting property, improve the work-ing life of tire dramatically.
A kind of engineering tire tread rubber of the present invention is realized by following technical scheme:
Described tread rubber comprises the component of following portions by weight:

Zinc oxide 1-8 anti-aging agent 1-10
Anti-recovery agent WK-9011-4 altax 0.5-2
Accelerant CZ 0.5-3.
Described natural rubber is 1# smoke sheet rubber or 3# smoke sheet rubber.
Described carbon black is N115 and N234.
Carbon black N115, N234 mix according to the ratio of weight ratio 1:1.
Described described anti-aging agent is anti-aging agent RD and antioxidant 4020.
Anti-aging agent RD and antioxidant 4020 mix according to the ratio of weight ratio 2:1.
Described described white carbon black is the precipitated silica of particle diameter 20-100nm.
Described a kind of engineering tire tread rubber, is grouped into by following one-tenth by weight:
Natural rubber 70 polybutadiene rubber 10
Solution polymerized butadiene styrene rubber 20 silane coupling agent Si-691.6
