Description
Technical field
The present invention relates to the old tire reconditioning technology, be meant the preparation method who adopts polyurethane elastomer material and General Purpose Rubber composite procuring tread.
Background technology
Along with The development in society and economy, car owning amount constantly increase, the production of tire and consumption also increase year by year, the tire enormous amount of scrapping every year.The reconditioning technology of old tire mainly contains traditional heat and turns over (the employing mould is high temperature vulcanized) and comparatively advanced cold the turning over (adopting natural gum low temperature precured tread technology) of technology at present.China mainly adopts high temperature vulcanized tyre retreading technology, has only minority factory to adopt low temperature precured tread technology.The overall technology level only is equivalent to external twentieth century seventies to the level eighties.Heat is turned over and is mainly used in renovation oblique tire, owing to vulcanize under HTHP, makes carcass distortion and aging easily, influenced the quality of retreads, so its distance travelled can only reach the 50-70% of new tyre.The external cold technology of turning over that is extensive use of advanced technology, cold turning over is suitable for radial-ply tyre and oblique tire, the distance travelled of renovation rear tyre can near in addition surpass new tyre, but carcass is had relatively high expectations, require before the renovation carcass is endured strict scrutiny.
Yet, no matter be that heat is turned over or the cold technology of turning over, all be to use General Purpose Rubber (natural gum, cis-butadiene cement, butadiene-styrene rubber) to produce tyre surface, need the big carbon black of a large amount of contaminatives of adapted, have the aromatic naphtha of carcinogenicity and other that environment is had the compounding ingredient of pollution, also can produce a large amount of waste water, waste gas in the production process.Therefore, at present in renovation old tire production and use environmental pollution comparatively serious.
The demand for development tire of automobile develops to more long-lived, safety, environmental protection, energy-conservation direction.Its wearability of the tire of polyurethane production, resistance to rolling, tear resistance be all apparently higher than the existing tire that uses, and can not produce discarded object, and therefore replacing existing rubber retreading tire with the polyurethane retreads is world's tyre retreading developing direction already.But have only General Purpose Rubber precured tread technology in the old tire renovation, and do not see the report of useful polyurethane-General Purpose Rubber composite procuring tread retreads.Make polyurethane-General Purpose Rubber composite procuring tread key and will resolve the adhesion problem of polyurethane and General Purpose Rubber.
Summary of the invention
