Description
Technical field
The present invention relates to tire manufacturing techniques fields, more particularly to a kind of low-heat-generation Tire support glue and its preparation side
Method and application.
Background technique
With the development of society, the accelerating rhythm of life, gradually increasing of the people to requirements such as traffic safety, high speed, environmental protection
By force, the tire as running safety first life, safety upgrade is very urgent, and the tire with explosion prevention function will
It can obtain the welcome of the majority of consumers.
In recent years, external car run-flat radial-ply tyre product gradually appears in the market, and the safety upgrade of tire is
It is widely recognized.
Run-flat tire is a kind of novel tire, still can be protected in the case where losing heart completely in the process of moving
The operability of vehicle is demonstrate,proved, with 80 kilometers/hour of speed safety traffics of F-Zero, for operating range up to 80 kilometers, this makes people
Drive routine become more safety and conveniently.Meanwhile under normal barometric pressure situation, the comfort of run-flat tire
With handling not less than conventional tire.With the raising of global environmental consciousness, automobile industry increasingly tends to vehicle light weight
Change and miniaturization, run-flat tire may also help in the burden and excess weight that people remove spare tyre from, reach fuel-economizing and subtract
The effect of row.
It is believed that this both safe and convenient, comfortable and environmentally friendly novel tire is bound to be more and more people
Received.But it is presently available for being difficult to meet the needs of people as the support glue product of run-flat tire.
Summary of the invention
Based on this, it is necessary in view of the above-mentioned problems, providing a kind of low-heat-generation Tire support glue and preparation method thereof and answering
With it is the preferred sizing material for being used to prepare run-flat tire that the Tire support glue, which has the effect of that generation heat is low,.
A kind of low-heat-generation Tire support glue, the raw material including following weight part ratio are prepared:
It finds after study, the repeated deformation of tire, tire material is caused to generate hysteresis loss and be changed into thermal energy.Cause
This, considers, run-flat tire should use low-heat-generation material as far as possible, and to the support glue portion of not easy heat radiation from square degree
Emphasis is answered to consider in position.And the kind and dosage of carbon black are affected to sizing material heat, should use the carbon black of low-heat-generation, but general
For, low-heat-generation black-reinforced performance is poor.
On the basis of the above, the present inventor by experiment repeatedly and screens, and has selected the rare earth cis-butadiene cement of low-heat-generation, can
