Description
Technical field
The present invention relates to rubber material processing technique fields, more specifically, it is related to a kind of high-mechanic solid tyre use
Rubber and preparation method thereof.
Background technique
Tire is the annular elastic rubber product that the ground connection in various vehicles or mechanically assembled rolls；It is typically mounted on
In alloy rim, vehicle body can be supported, buffers foreign impacts, realize the contact with road surface and guarantees the driving performance of vehicle.According to
The difference of the carcass structure of tire can be classified as pneumatic tire and solid tyre, and the Hyundai Motor overwhelming majority is using inflation
Tire, and the carcass of solid tyre be it is solid, do not have to cord as framework, it is not necessary to inflate, admittedly do not need the inner tube of a tyre or inner liner；Mesh
Preceding solid tyre is only used for the high load capacity vehicle or machinery run at a low speed；Solid tyre is generally divided into adhesive type and non-adhesive type two
Kind, the former refers to that rubber directly vulcanize the tire on wheel rim, the latter refers to vulcanize after be fixed on tire on wheel rim again.
In the prior art, application publication number is the patent application document of CN107099064A, discloses a kind of solid tyre
With rubber and preparation method thereof, the rubber includes following component: natural rubber, nitrile rubber, polybutadiene, acrylic acid hydroxyl second
Ester, graphene, nano-titanium dioxide, stearic acid, anti-aging agent, vulcanizing agent, coupling agent, filler.Preparation method includes: that will first gather
Close object to be placed in mixer and plasticates, graphene, hydroxy-ethyl acrylate, silane coupling agent be then added and continues to be kneaded, then again according to
Secondary addition remaining ingredient is completed to carry out dumping after being kneaded, and obtains the solid tyre rubber.
Different from air core tyre, solid tyre other than intermediate seldom hollow maintenance center of gravity, other parts be it is solid,
The reduction of air content causes the bearing capacity of solid tyre lower than pneumatic tire, but due to solid tyre have it is excellent resistance to
Mill, puncture resistance, therefore solid tyre still occupies main status on engineering truck.Due to tire bearing capacity with it is a variety of
Factor is related, and other than the air capacity filled in tire, the size of tire and the intensity of tire can influence tire
Bearing capacity, therefore can be by the mechanical strength of enhancing solid tyre, to promote its bearing capacity.Since solid tyre does not have cord
With skeleton, therefore the rubber consumption of solid tyre is very big, and which increases the costs of solid tyre；In order to reduce production cost,
Part raw rubber can be replaced using the natural rubber made by waste and old glue, but compared with natural rubber, the intensity of reclaimed rubber
And wear-resisting property is still poor, causes the bearing capacity of the solid tyre using reclaimed rubber production lower, wearability is poor.
Summary of the invention
One of the objects of the present invention is to provide a kind of high-mechanic solid tyre rubber, by with reclaimed rubber and day
Right rubber is the hose lining of primary raw material production, and load-carrying intensity is big, and good tread rubber is used as solid tyre with wear-resisting property
