Description
Technical field
The present invention relates to technical field of polymer materials, more particularly to a kind of thermoplastic elastomer (TPE).
Background technique
Standard bicycle pneumatic tire material is vulcanized rubber material, and wear-resisting property is excellent, in addition inflated inner tyre is set
Meter, good damping effect is all the first choice of cycle tyre all the time, but inflation tyre once touches sharp objects and is easy to happen
It blows out, causes not continuing to ride, and tire is vulcanized rubber material, is not easily recycled, causes the waste of resource.With this several years
The rapid development of shared bicycle, this inflatable tire is already no longer applicable in due to being easy to blow out, and inflation-free tire is just
It can solve this problem, and easy to replace and maintain, various regions fall over each other to develop non-filling gas bicycle tire material, wherein TPU material
Elasticity is good for material, and wear-resisting property is better than vulcanized rubber and by research, but TPU material price itself is more expensive than great, and foams
It is more difficult, do not come by large-scale popularization.
TPE material comfortable feel, hardness are adjustable, can secondary operation recycle, and with rubber
High resilience, referred to as second generation rubber, but TPE material wear-resisting property itself is poor, is unable to satisfy and exempts from making for inflation tyre
With requiring.Usually improve there are two ways to TPE is wear-resisting: a kind of pair of TPE material vulcanizes, but can sacrifice TPE material
Processing performance, and the recycling problem of unresolved conventional vulcanized rubbers, cost are also higher than conventional vulcanized rubbers；Another kind is by adding
The method for entering antiwear assistant, such as ultra-high molecular weight polyethylene (such as patent publication No.: CN 101845195B), but super high molecular weight
Molecular weight of polyethylene is generally higher than 1,500,000, and strand is very long, and segment is intertwine with each other, so that melt viscosity is very high, and to hot shearing
It is insensitive, it even if reaching 200 degree or more, still cannot soften, be difficult extrusion or injection molding, therefore with short grained after blending
Form disperses in the polymer, when being acted on by external force friction, to be difficult to play its wear-resisting effect completely.It is for another example added poly-
Tetrafluoroethene powder (such as patent publication No.: 102134365 B of CN) and vulcanized rubber powder, with ultra-high molecular weight polyethylene powder
Last principle is the same, is to disperse in the form of granules in the polymer, limited to wear-resisting property promotion, not fully reaches and exempts to fill
The wear-resisting requirement of gas tire.
