Description
Technical field
The invention belongs to full steel wire heavy load radial tire (TBR) manufacturing technology field, and in particular to one kind contains steel wire
Manufacture method of carbon nanometer tire tread of cord and products thereof.
Background technology
At present, it is increasing with full steel wire heavy load radial tire (TBR) application amount, it is replaced the useless mesh wheel to get off
Tire is also being continuously increased, and only tread contour polishes among these and carcass is undamaged, can apply traditional presulfurization bar shaped tire
What face remanufactured only accounts for 5% or so, and crown belt steel wire is ground with or is damaged, carcass is intact still the useless of value
Old tire then accounts for more than 40%, and the part junked tire can not remanufacture using bar shaped tyre surface, or be broken and rubber powder is made, or
Burned and refine oil by local method, or abandoned is stacked everywhere, for rubber sources in short supply by serious waste, environment is heavily polluted destruction.
Therefore, full steel wire heavy load radial tire is improved to remanufacture rate, carry out tire resources circulation recycling and environmental protection gesture must
OK.For junked tire in addition to using bar shaped tyre surface reproducing method, have on present society still has certain depth using the decorative pattern cut off
Old tire top remanufactured, but the old tire top cut off tries to gain hidden danger there is serious uneasiness and for example cuts off it in old tire top
The either sidewall explosion or tyre bead explosion in using process (rotating at a high speed) of preceding old tire, can all make crown not take charge of degree
Ground is damaged and phenomena such as light or heavy delamination or impaired steel belt occurs, in addition when cutting off old tire top due to checking not
In place, the problems such as still being broken by thorn there is belt hand hay cutter silk department, these all severely impact the peace for remanufacturing tire
Full performance.Therefore, old tire top cannot be used for tire and remanufacture.
In addition, CNT has excellent mechanical property, conduction, heat conductivility, thus it is considered as that polymer matrix is answered
The preferable mechanics of condensation material strengthens and function modified material, using composite material exhibits made of CNT go out good strength,
Elasticity and fatigue resistance, if applied on new tire tread, can greatly improve the overall performance of tire.
