Description
Technical field
The present invention relates to a kind of tire protector, relate in particular to a kind of type of resistance to puncture presulfurization tire protector.
Background technology
China is world rubber consumption big country, and along with the fast development of auto-industry and mining machinery, China becomes global first rubber country of consumption for years.China is a country that rubber sources is very deficient, neoprene dependence on import more than domestic more than 70% natural rubber and 40%, and imbalance between supply and demand is very outstanding.Within 2008, domestic all kinds of tire output is about 5.46 hundred million (comprising cycle tyre etc.), nearly 200,000,000 of junked tire growing amount.Due to the wretched insufficiency of natural gum and neoprene resource, directly promote the fast development of tyre rebuilding industry.China's tyre rebuilding industry starts to step into the ranks of tyre rebuilding big producing country of the world, used tire renovation amount cumulative year after year, within 2004 8000000,2005 9600000,2006, break through 1,000 ten thousand high pointes, within 2007, rise to again 1,100 ten thousand, 2008 1200 ten thousand, 2009 and reach 1,300 ten thousand.Along with environmental protection, cry energy-conservation, green product improve day by day, tyre rebuilding industry presents the situation of sustained, stable growth, related industries output value rapid growth thereupon.
But now a lot of new treated tires have been mainly used in the non-standard highway in town and country, or even be used in the severe road environments such as industrial and mineral, thereby cause rebuilding a tyre there is puncture in the poor situation such as road conditions, top load, impact the phenomenon of blowing out, affect the safety in utilization of tire, can not realize tyre rebuilding truly.Particularly, for the tire that adopts the precured tread mode of production to produce, while use, be prone to tyre explosion problem under anticyclonic pressure, high load capacity, severe road conditions condition, affected the safety in utilization of tire.Major cause is: because former tire has passed through long use, material property reduces because of the factor such as aging, tired, tire carries out after tire recapping, degradation under all ubiquity intensity decline, resistance to loading capability variation, shock resistance, current tire recapping is merely able to meet the basic operating needs of tire.
Chinese patent application CN102303483A discloses a kind of mine tire retreading technology, it adopts in former tire main body 1 polishing for the treatment of renovation and adds after adhesive glue, outside it, place again along hoop winding steel wire bracing ply, then add tread-rubber in the periphery of steel belt, the technological means of finally vulcanizing, on the basis of former steel belt, reinforce new steel belt, and the technological means that adopts mining and logging tyre tyre surface special glue to carry out the bonding of new steel belt is carried out the renovation of mining area vehicle tyre.
On the one hand, because adopting after former tire main body polishing, it adds adhesive glue, place outward along hoop winding steel wire bracing ply in tire body to be renovated, and after the mode that steel belt is bonded into one repairs, carry out again the process of tire entirety sulfuration, thereby its renovation manufacturing process relative complex, and the tire after existence renovation in use, its tyre surface easily occur aging and and between carcass, form exoneration, and tyre surface in use collapses and uses up piece and then affect defect or the deficiencies such as its safety in utilization, durability.On the other hand, this technical scheme is only applicable to the renovation processing of used tire, can not be directly used in the making of new tire.
