Description
Technical field
The present invention relates to a kind of tire tread glue, specifically, relate to a kind of all-steel radial tire tread rubber, belong to rubber skill
Art field.
Background technology
In recent years, along with global economic development, transporting equipment used in engineering construction and Mining Market is the most large-scale
Changing, this causes the demand sharp increase of the carrying duty being undertaken engineering machinery.Owing to mining-type all-steel load-bearing radial is taken turns
The use condition of tire tread glue and harshness thereof, load is big, and turning is many, is easily impacted, stings in tyre surface with the contact process on road surface
Pricking and cutting, this is the highest to the physical property requirements of mining-type TBR tire tread.
So far, though in open source literature TBR tire tread formula lay particular emphasis on solution certain in terms of
Compound physical performance need, but fail the relation of the every physical and mechanical properties of aggregate balancing tread mix；It addition, current all steel
Radial-ply tyre tread rubber cost is high.
At present, China's scrap rubber utilizes and is broadly divided into three bulks: tyre rebuilding, the production of rubber powder, the production of reclaimed rubber.Its
In, with fastest developing speed is reclaimed rubber industry, and its scrap rubber utilized has reached the 80% of total utilization.Reclaimed rubber gives up rubber in China
Glue utilizes field to show one's talent, and necessarily has its existent value: one is other rubber the most winning in reclaimed rubber and quality, and some are general
Logical rubber can be used alone reclaimed rubber and produces, and can be effectively improved the extrusion of sizing material in natural gum after mixing partial regeneration glue
And drawability, and Index Influence is the least；Two is inseparable with the effort of enterprise in the industry and self-discipline, just speaks of reclaimed rubber in the past
Necessarily associating secondary pollution, this is also the reason that some viewpoint domestic opposes development reclaimed rubber.Removed from office by technology in recent years
Newly, technique for regenerated rubber is become present high temperature dynamic method by original water/oil method, oil process, waste gas achieve concentration discharge,
Process, reclaim, substantially achieve that pollution-free, Harmless produces, production technology is reached advanced world standards, and forward is green
Environmental protection direction strides forward.
At the beginning of reclaimed rubber industry development, it is the heaviest that its part replaces natural rubber and elastomeric purposes to make it have
The strategic position wanted, is especially considering that China's natural rubber is under-supply, the predicament of long-term dependence on import, uses reclaimed rubber
Significant.
