Abstract
The invention discloses a tire self-mending agent and a method for preparing the tire self-mending agent. The tire self-mending agent comprises, by mass, 30-40% of deionized water, 0.1-1% of polyvinyl alcohol, 0.5-1% of cellulose ether, 1-5% of plant fiber, 0.1-1% of nanometer inorganic filler, 40-50% of alcohol antifreezing agent, 1-5% of rubber particle, 0.5-2% of calcined gypsum, 0.1-1% of sodium nitrite and 5-10% of latex. A plug and a leakage-proof film formed by the self-mending agent after the self-mending agent is dried can seal a crack permanently, and the tire self-mending agent is good in air tightness, prevents a tire from leaking air, can endure heavy loads, and endures impact with the road surface. The tire self-mending agent is convenient to use, nontoxic, free of extraneous odor and strong in mending capacity and can be used for mending 8mm cracks in an inner tube of a motorcycle, 10mm cracks in a vacuum tire of a motorcycle, 20mm cracks in a vacuum tire of an automobile and 40mm cracks in a vacuum tire of an engineering machinery vehicle.
Description
Technical field
The present invention relates to a kind of self-mending agent for tyre puncture, particularly relate to a kind of self-mending agent for tyre puncture and preparation method thereof and application thereof.
Background technology
Along with social development, the use of vacuum tire on motorcycle, automobile in recent years is increasingly extensive.Vacuum tire has higher elasticity and wear resistance, and good sticking power and heat dispersion are arranged, and its security, comfortableness, stability are all high than conventional tyre.Due to the vacuum tire tubeless, repair trouble, and it is higher to repair cost, therefore in use should avoid being punctured by sharp object as far as possible.Once tire is punctured gas leakage, be easy to cause potential safety hazard.The at present vacuum tire of motorcycle gas leakage, is all to adopt to beat the method for rubber peg usually, but must strengthen breach while beating rubber peg, and this has not only destroyed tire artificially, and still can have gas leak phenomenon after benefit.
Self-mending agent for tyre puncture is a kind ofly tire to be punctured to gas leakage by sharp object the fluent material of the ability of repairing is more by force arranged.Filling from tonic in tire, when tire is punctured by sharp object, under the effect of vehicle own wt and tire pressure, can mouthful block along with the air flow direction breach will leak gas from tonic, thereby prevent from having a flat tire.At present domestic self-mending agent for tyre puncture kind is a lot, also very effective to the repairing of normal temperature, little small opening, but still has many defects, mainly comprise: (1) corrosion wheel rim, wheel rim is got rusty, tire is had to side effect, make tire hardening distortion, premature aging, affect work-ing life of tire; (2) breach of repairing is little, can only mend little breach, can't mend large hole; (3) can not mend the inner tube of a tyre; (4) antifreeze limited in one's ability, under severe cold condition, use can cause gel and freezing, and can not restore after freezing, or new combination reaction occur because of tyre temperature when too high tire patching was lost efficacy.
Summary of the invention
The objective of the invention is in order to solve above-mentioned the deficiencies in the prior art part, provide a kind of corrosion-free to wheel rim, can mend large hole, resistance to frost is good, resistance to air loss is good, self-mending agent for tyre puncture that environment, human body and tire are had no adverse effects of good stability and preparation method thereof.
Realize that the technical scheme that the object of the invention adopts is:
A kind of self-mending agent for tyre puncture, in the mass percent of material component, this self-mending agent for tyre puncture is comprised of following component: deionized water 30～40%, polyvinyl alcohol 0.1～1%, ether of cellulose 0.5～1%, vegetable fibre 1～5%, nanometer inorganic filler 0.1～1%, alcohols frostproofer 40～50%, rubber grain 1～5%, the plaster of Paris 0.5～2%, Sodium Nitrite 0.1～1% and latex 5～10%;
During preparation, in the deionized water of ionized water raw materials quality 40～80% that accounts for, add polyvinyl alcohol, stir at 80～95 ℃ of temperature, add vegetable fibre to stir again, be cooled to normal temperature, obtain solution one; Add ether of cellulose in the remaining deionized water of raw material, stir under 50～80 ℃, add nanometer inorganic filler, then stir, then be cooled to normal temperature, obtain solution two; Solution one and solution two are mixed, add the alcohols frostproofer to stir under room temperature, then add rubber grain, Sodium Nitrite, the plaster of Paris to continue to stir; Add latex, under room temperature, stir and get final product;
Described nanometer inorganic filler is one or more in polynite, kaolin, aerosil and nano-calcium carbonate;
