Description
Technical field
The present invention relates to a kind of tire for vehicle conventional tyre safety upgrade from sealing and manufacture method thereof.
Background technology
The vehicle wheel that vehicle uses at present, has two types, and one has inner tube of a tyre vehicle wheel, another kind of tubeless vehicle wheel, and what in institute's passenger vehicle, substantially all use at present is tubeless vehicle wheel, progressively promotes the use of tubeless vehicle wheel for load-carrying vehicle national requirements.Because having the good and inflation of good thermal diffusivity, flexibility, stopping property, ride comfort, performance, tubeless vehicle wheel uses the advantages such as interval time is long, but when tubeless vehicle wheel tire is punctured by sharp object, because sharp object residues in vehicle wheel carcass, the high pressure gas of vehicle wheel tire is known from experience and is outwards leaked or blow out puncturing position; When sharp object pierces through vehicle tyre and departs from vehicle tyre, the high pressure gas in tubeless vehicle wheel leak rapidly, if vehicle is blown out or leaked rapidly two kinds of situations in the process of running at high speed, car accident occur dangerous large, and car crash probability is high.
On the eighties in last century market, major technique is presented as the technological method in self-styled liquid glue perfusion vehicle wheel, just has at that time multiple tire from sealing on market, is injected in vehicle wheel tire.Along with the rotation of vehicle wheel is evenly distributed in the internal surface of vehicle wheel tire, in the time that vehicle wheel tire is punctured by sharp object, cause vehicle wheel to have a flat tire, tire from sealing and airborne oxygen reaction and solidify, reaches the object of vehicle wheel tire leakproof.Its technological method shortcoming is, in liquid glue and air, oxygen reaction forms the brilliant elasticity that can reduce vehicle wheel tire of one deck scleroma, has a strong impact on various technical features and the life-span of vehicle wheel tire, do not received by market.Say that important breakthrough appears in century this technical field of the nineties, found a kind of more advanced in sealing, it is the solid-state sticky jelly such as polyisoprene rubber or butene rubber or silicon rubber that sprays one deck 2～3mm in vehicle wheel, the micro-gas leakage that solves vehicle wheel tire with this kind of solid-state sticky jelly, the phenomenon of gas leakage while being punctured by sharp object.Adopt polyisoprene rubber or the solid-state sticky jelly such as butene rubber or silicon rubber, make shellproof, the leakproof of vehicle stove tire, the upgrade technique of resistance to bundle use and step further to real market, but there is many disadvantages and unfavorable factor: 1) because polyisoprene rubber, butene rubber, silicon rubber are all the important members in synthetic rubber, the very wide cost of material of range of application is high; 2) activity of this type of rubber, ageing resistance all cannot obtain substantial technological breakthrough, is difficult to prolonged application under the severe Working environment of vehicle wheel; 3) the solid-state sticky jelly coating of the polyisoprene rubber in vehicle wheel tire, butene rubber, silicon rubber, in service at vehicle high-speed, vehicle wheel tire and ground friction, heat up too high and coating in tire of tire, under centrifugal action, there is local deformaton, affect the transient equilibrium of vehicle wheel; 4) polyisoprene rubber, butene rubber, the silicone rubber material that adopt, cost and industrialized development all become the factor of its popularization of restriction.
Recent years, along with the fast development of petrochemical technology, continuing to bring out of various macromolecule resin class tackiness agents, synthetic rubber and rubber composite, the external high polymer elastic glue-leakage-resistant material of promoting has entered my domestic market, due to the external import of conventional raw material, price is high, the limited product simplification that causes of supplying, cause this high polymer elastic glue-leakage-resistant material to come into the market to run into many difficulties, also hindered the industry development process of domestic this product simultaneously.
Therefore, founding and release a kind of high temperature resistant, low temperature resistant while has again the constructed performance of international high polymer elastic glue-leakage-resistant, with low cost and can domesticly complete " the heatproof high molecule elasticity glue-leakage-resistant " of the purchasing of raw materials completely, become and really can make the march toward bottleneck problem of industrialization and marketability of vehicle conventional tyre upgrading.
As can be seen here, above-mentioned existing vehicle wheel upgrading from sealing aspect, obviously still has many defects with tire.But its product is simple at first view, in fact very complicated, tire is very high because it is the basic guarantee of vehicle operating safety from sealing technical requirements, next is along with vehicle wheel tire need stand the larger high low temperature temperature difference and the test of long-time bearing pressure work, and to transient equilibrium, run at high speed, the safety index of durability of product requires high especially, bear the low temperature of-40 ℃, after in the time that vehicle high-speed moves, vehicle wheel tire is punctured, pierces through, tire is self-complementary and keep one's end up from sealing.Vehicle at a high speed, under the long-time travel situations of high temperature, when vehicle wheel tire periphery envrionment temperature can reach 120 ℃ of left and right, after tire is punctured, pierces through, tire is self-complementary and keep one's end up from sealing.Existing tire is difficult to reach this requirement or because tire is not firm from sealing poor adhesive force and vehicle wheel tire inner wall surface adhesion from sealing, tire comes off or the defect of off-clip from adhesive layer, and is difficult to reach the undismayed function and efficacy of vehicle wheel tire after upgrading.And need be further improved.In order to solve the problem of above-mentioned existence, relevant manufacturer and research institute, the there's no one who doesn't or isn't hard thought of institute are asked scheme solution, are found from sealing but have no for a long time applicable tire always.Therefore how to found a kind of new tire from sealing, be used for solving vehicle wheel tire upgrading Explosion-Proof, make it really can make the vehicle conventional tyre upgrading industrialization and marketability of marching toward, real one of the current important research and development problem that belongs to, also becomes current industry and puts aside improved target.
Summary of the invention
Adopting tire to be sprayed at vehicle wheel tire inner wall from sealing is the key problem in technology of vehicle wheel upgrading: the one, and tire should have high elasticity, resistance to air loss, tensile strength from sealing; Its two tire has strong sticking power from sealing and vehicle wheel tire inner wall surface.Analyze some existing tires from sealing, some substantially meets key problem in technology " " requirement on functional performance, but is that the sticking power aspect on vehicle wheel tire inner wall surface fails to reach key problem in technology " twos' " requirement.Its reason is, the material of vehicle wheel tire is vulcanized rubber, and surface is inertia very, and most of materials and its are difficult for bonding, and the vehicle wheel tire inner wall top coat after upgrading very easily separates with tire inner wall in Vehicle Driving Cycle process.Thereby slacken or lose the vehicle wheel tire leakproof after upgrading, resistance to bundle function.Founding a kind of tire and both met key problem in technology " " from sealing, meet again key problem in technology " twos' " requirement, is exactly purpose of the present invention.
Particularly, the object of the invention is to, overcome the defect that existing tire exists from sealing, and a kind of high temperature resistant (being greater than 120 ℃), low temperature resistant (lower than-40 ℃), oil-proofness, water tolerance are provided, and the tire for vehicle conventional tyre safety upgrade with snappiness, height resistance to air loss, high-tensile and strong adhesive force is from sealing.
