Description
Technical field：
The present invention relates to a kind of graphene oxide/rubber nano composite material applied to tread rubber for engineering tire, especially relate to
And to a kind of formula of tread rubber for engineering tire, belong to tread rubber for engineering tire technical field.
Background technology：
Tread rubber is special part and parcel in tire construction, the rubber layer that the outermost of finger wheel tire is contacted with road surface.It
Effect be to prevent the abrasion of tire early stage and avoid mechanical damage, transmission tractive force and brake force, during traveling from cushioning effect.
Therefore tread rubber needs tool to have good wearability, cut resistant energy, wet-sliding resistant performance and obdurability, good ageing-resistant performance,
Higher tensile strength etc..Engineering tyre is usually used in the more complicated road surface of some road conditions, thus the tread rubber of engineering tire is more needed
There are well wear-resisting, cut resistant and other performances.
As the derivative of graphene, the structure and graphene of graphene oxide are substantially similar, simply in edge and two
Containing some oxygen-containing functional groups on dimensional plane, such as-OH ,-COOH ,-O-etc..The presence of these functional groups causes graphite oxide
The structure of alkene becomes complicated.Current educational circles is it is believed that graphene oxide is on the basis of graphene-structured, on its surface point
Cloth hydroxyl and epoxy radicals, and contains a small amount of carbonyl and carboxyl at its edge.The structure of graphene oxide is as follows：
Compared with graphene, graphene oxide not only inherits many excellent characteristics of graphene, and such as Young's modulus reaches
1TPa, tensile strength is 130GPa, and specific surface area reaches 2630m2/g.And because the functional group that graphenic surface contains has
Hydrophily, this causes what graphene oxide can be well in water to disperse.
The unique structure of graphene oxide makes it possess various excellent performances, and a small amount of filling is with regard to that can make polymer
Performance is improved.Wu Jinrong etc. will pass through solution blending legal system by modified graphene oxide SGO with natural rubber (NR)
SGO/NR nano composite materials are obtained, 0.3% SGO is added, the tensile strength of material can just improve 10%, and stress at definite elongation is carried
High by 66%, air-tightness is to improve 48%.Jiang waits quietly using polystyrene sodium sulfonate (PSS), cetyl trimethyl
Ammonium (CTAB), detergent alkylate sodium sulfonate (SDS) are modified to graphene oxide, and further prepare graphite with hydrazine hydrate reduction
Alkene/carboxyl butyronitrile rubber (XNBR) nano composite material.It was found that adding after graphene, the heat-resisting and heat conductivility of material is
Increase, and the PSS in terms of modified effect>CTAB>SDS>It is unmodified.
The content of the invention：
It is an object of the invention to provide the more excellent engineering tire such as a kind of mechanical property, belt cutting-resisting property, anti-wear performance
Tread glue formula, can significantly improve cut resistant, the anti-wear performance of large off-the-road (OTR) tire, extend the service life of tire.The present invention
Butadiene-styrene rubber, natural rubber are used for matrix, it is composite filled with modified graphene oxide and carbon black.In two-roll mill with
Activator, age resistor, softening plasticizer, accelerator and sulphur mixing, then obtain vulcanizate through vulcanizing press vulcanization.The formula
Vulcanizate possess more excellent mechanical property, cut resistant and anti-wear performance.Tensile strength is in 16-24.1MPa, in 1.61km
Akron abrasion loss in 0.441-0.096cm3, 20min cutting quantities are run on dynamic cutting test machine in 1.0165-
