Abstract
The invention relates to tire tread rubber special for a shop truck. According to the tire tread rubber, adopted high vinyl polybutadiene rubber can effectively improve the wear-resisting property of the tire tread rubber, in addition, under the synergistic effect of other components in the tire tread rubber, the wear-resisting property and ageing resistance of the rubber are further improved, the wear-resisting property of the rubber is improved while the requirements of tire tread cut resistance, chunking and falling resistance are met, and the service life of a tire is greatly prolonged.
Description
Technical field
The invention belongs to tire manufacturing techniques field, be specifically related to a kind of engineering truck special tyre 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 truck special tyre 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 truck special tyre tread rubber of the present invention is realized by following technical scheme: described tread rubber comprises the component of following portions by weight:
Natural rubber 20-50 high vinyl polybutadiene rubber 20-80
Solution polymerized butadiene styrene rubber 20-80 silane coupling agent Si-691-4
Stearic acid 1-4 protection wax 1-3
Sulphur 1-4 amine-BSA1-5
Carbon black 10-50 white carbon black 7-15
Process oil 3-10 resol resin 1-4
Zinc oxide 1-8 anti-aging agent 1-10
Anti-recovery agent WK-9011-4ISAF1-30
Altax 0.5-2 accelerant CZ 0.5-3.
Described high vinyl polybutadiene rubber Mooney viscosity 65-80, contents of ethylene 85-90%.
Described carbon black is N339.
Described anti-aging agent is antioxidant 4020.
Described white carbon black is the precipitated silica of particle diameter 20-100nm.
Described petroleum resin are coumarone petroleum resin.
Described natural rubber is 1# smoke sheet rubber or 3# smoke sheet rubber.
Described a kind of engineering truck special tyre tread rubber, is grouped into by following one-tenth by weight:
Natural rubber 30 high vinyl polybutadiene rubber 30
Solution polymerized butadiene styrene rubber 40 silane coupling agent Si-691.4
Stearic acid 1.2 protection wax 1.6
Sulphur 2.5 amine-BSA2
Carbon black 45 white carbon black 12
Process oil 6 resol resin 2
Zinc oxide 4 anti-aging agent 1.5
Anti-recovery agent WK-9011ISAF8
Altax 0.8 accelerant CZ 1.5.
Beneficial effect of the present invention is, tread rubber of the present invention, tire wear, resistance to deterioration are good, the mixing of the natural rubber adopted, high vinyl polybutadiene rubber, solution polymerized butadiene styrene rubber, effectively can improve the wear resisting property of tread rubber, high vinyl polybutadiene rubber, has good wet-sliding resistant performance, lower rolling resistance and heat-dissipating.
In addition, the interpolation of the interpolation of each ancillary component further increases wear resisting property and the ageing resistance of rubber.The present invention by rational proportion design, make the sizing material of gained meet tire resist collapse use up block while improve its wear resisting property, Using Life of Tyre is improved largely.
It is crown in two side three block structures or upper, middle level tread rubber part that sizing material provided by the invention only can be used as tyre surface working design, with have compared with low-heat-generation Tire shoulder rubber material with the use of, there is the defects such as early stage shoulder is empty to avoid tire.
