Description
Technical field
The present invention relates to solid tyre fields, and in particular to be a kind of good solid tyre of wet type on-slip and its molding work
Skill.
Background technology
According to Baidupedia, tire refers to the circular ring shape elasticity rubber rolled in various vehicles or the ground connection mechanically assembled
Glue product, it is typically mounted on holder, can support vehicle body, buffering foreign impacts etc..Bicycle, perambulator and toy car etc.
For light non-motor vehicle, own wt is small, and the load that tire is born is small, therefore tire used belongs to a kind of low load wheel
Tire.For above-mentioned low load tire, the elasticity and portability of tire itself are to the handling particularly important of vehicle.Used in the market
Low load tire includes mainly pneumatic tire and non-inflatable tyre.Subject to damage during pneumatic tire use, for small size
Low load tire, replace more difficult, therefore pneumatic tire is rarely applied on baby carriage tires and toy tyre.Exempt from inflated wheel
Tire can to avoid pneumatic tire there are the problem of, can be widely applied to the fields such as perambulator, toy.Non-inflatable tyre includes not foaming
Solid tyre, foaming solid tyre and foaming body filled-type tire etc..
Rubber is usually used as epidermis, to play wear-resisting and on-slip effect, still in traditional solid tyre
Since blending is poor each other between rubber and TPU expanded particles so that be often easy to happen positioned at internal layer TPU foaming bodies and
The situation being disengaged from each other positioned at the rubber of epidermis, so that solid tyre encounters difficulty during practical industrialization
Topic.
Based on the above considerations, the present inventor had once applied for a kind of thermoplastic polyurethane low load tire comprising uses
It is hard higher than inner layer in the hardness of the epidermis directly contacted with ground and the inner layer inside epidermis, the epidermis
Degree, the epidermis and inner layer are foaming-formed using TPU expanded particles.But whether how to be carried out using TPU expanded particles
Molding, is promoted relatively limited on wear-resisting and non-skid property, is based on this, the applicant's hammer away regarding to the issue above,
Then there is this case generation.
