Description
Technical field
The invention belongs to tyre production technical fields, and in particular to a kind of ageing-resistant tread rubber of tire.
Background technique
China's tire annual output ranks first in the world, but is not also tire power, and external tire enterprise is in high-performance tire system
Implementation technology and trade barrier are made, cause domestic tire quality to can only achieve low and middle-end, enterprise profit is meagre；At the same time,
China has a large amount of waste rubber goods to be taken as waste product and garbage disposal every year, not only causes a large amount of wasting of resources, also causes
" black pollution " become the environmental problem that gets worse.And it focuses mostly on to the recycle of waste tire turned in tire at present
Newly, on the low-grade product such as environmental friendly regenerated glue and rubber powder production.
With the continuous improvement that tire tag method requires tire drag and wearability, new rubber material and reinforcement
Material is constantly applied in tire material, such as Rare-earth Cis fourth, solution polymerized butylbenzene rubber clone and carbon nanotube, graphene etc. are novel
Supporting material；Currently, constantly there is the appearance of the new concepts tire such as " carbon nanotube tire ", " graphene tire " both at home and abroad；These are new
The application of material improves the performance of tire really, but due to expensive, is essentially still at the laboratory publicity stage,
It there is no industrialization, commercialization tire circulation listing at present；Application No. is disclose a kind of carbon nanotube in 201710259133.4
Composite high-performance tire utilizes environmental friendly regenerated glue, carbon nanotube rubber master batch, cracking black carbon, natural rubber, zinc oxide, two with tread rubber
Butyl stannous chloride, coupling agent and vulcanizing agent rational proportion, disperse carbon nanotube effectively in tread rubber, reduction is produced into
This has the characteristics that wearability and thermal coefficient height, durable heat are low, and wearability is improved there has also been certain, but with tread rubber
It is required that continuous improvement, the technical effect realized in the prior art can no longer meet actual demand, tear-proof, stretch-proof
Intensity and ageing-resistant performance all need to be further strengthened, but the performance of reclaimed rubber limits the raising of its comprehensive performance.
