Description
Technical field
The present invention relates to solid tyre field, particularly to a kind of heat resistant type solid tyre carcass glue.
Background technology
On ordinary meaning, tire is the annular elastic rubber product rolled at various vehicles or the ground connection mechanically assembled.Logical
Often it is arranged in alloy rim, vehicle body can be supported, buffer foreign impacts, it is achieved with the traveling contacting and ensureing vehicle on road surface
Performance；Solid tyre is a kind of tire corresponding with pneumatic tire (air core tyre), and its carcass is solid, without cord
Make skeleton, it is not necessary to inflation, therefore be not required to the inner tube of a tyre or inner liner.Tire the earliest is exactly solid tyre, and solid tyre is the most only used
In the high load capacity vehicle run at a low speed or machinery, it is also used for the machinery of fixed position.
Tire often uses under exacting terms complicated, and it subjects various deformation, load, power and height in motion
Temperature effect, it is therefore necessary to there is higher load-carrying properties, hauling ability, shock-absorbing capacity.Meanwhile, also require possess high abrasion
Property and flexible resistance, and low resistance to rolling and heat generation.The world consumes the half of rubber mass for tire production.
Midsummer arrives, and temperature raises day by day.This season is the most hard to bear for automobile.Because automobile is at work originally
Body is accomplished by the substantial amounts of heat of dissipation, adds the high temperature in the external world, and the many rubber components aggravation on car can be made aging, and high temperature
It is aging that the glue surface of lower tire is easier to generation, arises that and blows out, bring personal safety hidden danger to driver time serious.
Microporous polyurethane elastomer foaming tire has higher bearing capacity and wearability.From tradition rubber tyre unlike it
Well anti-cut is cut and tear resistance, and moulding process is simple, and equipment investment is low；Tire is non-inflatable, thus eliminates and make
Causing, because of sharp object puncture, the misgivings that pneumatic tire is disappointing, leak gas during with, it is the most convenient to use.But its interior molecules is tied
The thermostability that structure determines polyurethane material is poor, and temperature rising can cause the dynamic physicals such as tire fatigue durability, flexible resistance
Performance is decreased obviously.Polyurethane foam tire is only when low speed uses, and performance just can be guaranteed.
Summary of the invention
For it is an object of the invention to the tire poor heat resistance solving to utilize conventional polyurethanes foam pattern to make in prior art,
And the defect such as the scarce capacity that subject various deformation, load and power.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of heat resistant type solid tyre carcass glue, including following material: neoprene, polymer polyatomic alcohol, cross-linking agent, expansion
