Description
Technical field
The present invention relates to a kind of seal gum and preparation method thereof, specifically a kind of polymer selfsealings polymkeric substance for doughnut and preparation method.
Background technology
The automotive wheels that current vehicle uses, have two types, one has inner tube of a tyre automotive wheels, and another kind of automobiles without inner tubes wheel, substantially all uses automobiles without inner tubes to take turns in current institute passenger vehicle, and automobiles without inner tubes wheel is progressively promoted the use of in load-carrying vehicle national requirements.It is good that automobiles without inner tubes wheel has good thermal diffusivity, flexibility, stopping property and ride comfort performance, the advantages such as inflation uses interval time long, but when automobiles without inner tubes tire is punctured by sharp object, because sharp object residues in automotive wheels carcass, the high pressure gas of doughnut is known from experience and is outwards leaked or blow out puncturing position; Pierce through doughnut when sharp object and depart from doughnut, the high pressure gas in automobiles without inner tubes wheel leak rapidly, if automobile is blown out in the process of running at high speed or leak two kinds of situations rapidly, motor-vehicle accident occurs dangerous large, car crash probability is high.
On the eighties in last century market, major technique is presented as the technological method in selfsealings liquid glue perfusion automotive wheels, at that time market just has multiple self-sealing tire mending-leakage glue, and is injected in doughnut.Rotation along with automotive wheels is evenly distributed in the internal surface of doughnut, when doughnut is punctured by sharp object, causes tyre leakage, the oxygen reaction in self-sealing tire mending-leakage glue and air and solidifying, and reaches the object of doughnut leakproof.Its technological method shortcoming is, in liquid glue and air, oxygen reaction forms one deck and hardens brilliant thus reduce the elasticity of doughnut, has a strong impact on various technical feature and the life-span of doughnut, not receive by market.Last century there is important breakthrough in this technical field of the nineties, found a kind of more advanced selfsealings glue, it is the solid-state sticky jelly such as polyisoprene rubber or butene rubber or silicon rubber etc. spraying one deck 2-3mm in automotive wheels, micro-gas leakage of doughnut is solved, the phenomenon of gas leakage when being punctured by sharp object with this kind of solid-state sticky jelly.Adopt the solid-state sticky jellies such as polyisoprene rubber, butene rubber or silicon rubber, shellproof, the leakproof of doughnut, the upgrade technique of resistance to bundle are used to real market to be stepped further, but there is many disadvantages and unfavorable factor: 1) due to the important member that polyisoprene rubber, butene rubber, silicon rubber are all 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 automotive wheels harsh environments; 3) the solid-state sticky jelly coating of the polyisoprene rubber in doughnut, butene rubber, silicon rubber, in high-speed running automobile, doughnut 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 automotive wheels; 4) polyisoprene rubber adopted, butene rubber, silicone rubber material, cost and industrialized development all become its factor promoted of restriction.
Recent years, along with the fast development of petrochemical technology, various macromolecule resin class tackiness agent, synthetic rubber and rubber composite continue to bring out, the high polymer elastic glue-leakage-resistant material of external popularization enters domestic market, due to the external import of conventional raw material, price is high, supplies limitedly to cause product simplification, cause this high polymer elastic glue-leakage-resistant material to come into the market to run into many difficulties, also counteracts that the industry development process of this product domestic 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 domesticly can complete ' the heatproof high molecule elasticity glue-leakage-resistant ' of the purchasing of raw materials completely, become the bottleneck problem that doughnut really can be made to upgrade march toward industrialization and marketability.
Existing automotive wheels upgrading polymer selfsealings polymeric gel aspect, still has many defects.This series products is simple at first view, and in fact very complicated, the technical requirements of polymer selfsealings hot melt is very high.Because it is the basic guarantee of vehicle operating safety, the automotive wheels tire in using need undergo the larger high/low temperature temperature difference and the test of long-time bearing pressure operation, to its transient equilibrium, run at high speed, the safety index requirement such as weather resistance is high especially.Polymer selfsealings polymeric gel should when-45 DEG C of low temperature, vehicle high-speed run automotive wheels tire punctured, pierce through after self-complementary and keep one's end up, again doughnut ambient temperature up to 120 DEG C time, under the long-time travel situations of vehicle high-speed, tire is punctured, pierce through after, self-complementary and keep one's end up.Existing polymer selfsealings polymeric gel be difficult to reach this require many due to polymer selfsealings polymeric gel poor adhesive force and automotive wheels tire inner wall crown type surface adhesion not firm, cause polymer selfsealings polymeric gel pull-up to fall or the defect of off-clip, and be difficult to the undismayed function and efficacy of automotive wheels tire after reaching upgrading.
In order to solve above-mentioned Problems existing, the there's no one who doesn't or isn't hard thought of relevant manufactures and institute asks scheme solution, but has no applicable polymer selfsealings polymkeric substance for a long time always and be found.Therefore solution doughnut upgrading leakproof is anti-lets out problem for making how to found a kind of new polymer selfsealings polymeric gel processing method, make it that doughnut really can be made to upgrade to march toward industrialization and marketability, one of current important research and development problem of real genus, also becomes the target that current industry is badly in need of improving.
