Description
Technical field
The present invention relates to a kind of polymeric seal rubber powder, particularly relate to a kind of polymeric seal rubber powder with high safety performance.
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, tubeless vehicle wheel is progressively promoted the use of in load-carrying vehicle national requirements.Tubeless vehicle wheel has the advantages such as good thermal diffusivity, flexibility, stopping property and ride comfort performance are good, inflation use length interval time, 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 self-sealing tire mending-leakage glue 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, self-sealing tire mending-leakage glue and airborne oxygen reaction and solidify, reach the object of vehicle wheel tire leakproof.Its technological method shortcoming is, in liquid glue and air oxygen reaction form one deck scleroma brilliant its reduce the elasticity of vehicle wheel tire, have a strong impact on various technical features and the life-span of vehicle wheel tire, do not received by market.There is important breakthrough in this technical field of the nineties last century, found a kind of more advanced in sealing, by solid-state to the polyisoprene rubber or butene rubber or the silicon rubber etc. that spray one deck 2-3mm in vehicle wheel sticky jelly, 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 wheel 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, tire intensification is too high causes the coating in tire, under centrifugal action, local deformaton occurs, and affects 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 restriction popularization.
Recent years, along with the fast development of petrochemical technology, various macromolecule resin class tackiness agents, synthetic rubber and rubber composite continue to bring out, the external high polymer elastic glue-leakage-resistant material of promoting has entered 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, found and release a kind of high temperature resistant, low temperature resistant, there is again the constructed performance of international high polymer elastic glue-leakage-resistant simultaneously, 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 tyre upgrading.
The existing vehicle wheel self-styled hot-melt adhesive powder of polymer aspect for upgrading, still has many defects.This series products is simple at first view, in fact very complicated, and the self-styled hot-melt adhesive powder technical requirements of polymer is very high.Because it is the basic guarantee of vehicle operating safety, in use, vehicle wheel tire need stand the test of working under the larger high low temperature temperature difference and long-time bearing pressure, to its transient equilibrium, run at high speed, the safety index requirement such as weather resistance is high especially.The self-styled hot-melt adhesive powder of polymer should be at the low temperature of-40 DEG C, vehicle high-speed when operation vehicle wheel tire is punctured, is pierced through rear self-complementary and keep one's end up, vehicle is under high speed, the long-time travel situations of high temperature again, vehicle wheel tire periphery envrionment temperature is during up to 120 DEG C of left and right, after tire is punctured, pierces through, self-complementary and keep one's end up.The self-styled hot-melt adhesive powder of existing polymer be difficult to reach this require many due to the self-styled hot-melt adhesive powder poor adhesive force of polymer and vehicle wheel tire inner wall surface adhesion not firm, cause the self-styled hot-melt adhesive powder pull-up of polymer to fall or the defect of off-clip, and be difficult to reach the undismayed function and efficacy of vehicle wheel tire after upgrading.
In order to solve the problem of above-mentioned existence, the there's no one who doesn't or isn't hard thought of relevant manufacturer and institute is asked scheme solution, is found but have no for a long time the applicable self-styled hot-melt adhesive powder of polymer always.Therefore how to found the self-styled hot-melt adhesive powder of a kind of novel polymer, be used for solving vehicle wheel tire upgrading Explosion-Proof, make it really can make the vehicle 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 is badly in need of improved target.
Because the defect that the self-styled hot-melt adhesive powder of above-mentioned existing polymer exists, practical experience and the expertise of the inventor based on being engaged in this type of product design manufacture and enriching for many years, and the utilization of cooperation scientific principle, actively research and innovation in addition, to founding a kind of novel polymeric seal rubber powder with high safety performance, can improve the self-styled hot-melt adhesive powder of general existing polymer, make it have more practicality.Through constantly research, design, and after repeatedly studying sample and improving, finally create the present invention who has practical value.
