Abstract
The invention provides an automatic tire patching agent, which comprises an air pressure agent, an air pressure inhibiting agent, gels, rubber particles, fibers, solvents, additives and nanometer carbon powder. After the automatic tire patching agent provided by the invention is added with the nanometer carbon powder, the bonding characteristic is enhanced, the condensing shrinkage rate of the tire patching agent is reduced, and meanwhile, the friction resistance performance of tires is improved.
Description
Technical field
The invention belongs to the chemical binder field, relate in particular to a kind of automatic tyre mending agent.
Background technology
Doughnut in use weares and teares, to be pricked, leak gas be inevitable, the tire patching technology that is absolutely necessary.
At present automotive tire repair agent mainly contains two kinds:
A kind of is the liquid-type healant of not inflating, before the running car prerequisite, be injected in the tire, and in running car, wheel rolling, inside wheel produces centrifugal force, and under the effect of centrifugal force, the liquid-type healant is uniformly distributed in inside tires.Blowing out or during puncture of tire, liquid healant can reach the place, cavity at short notice, repairing bonding to stop gas leakage; But the time of coagulation of this repairing method is long, and the rear weak effect that condenses, and is not wear-resisting, easily again gas leakage.Simultaneously long-term filling liquid in tire can affect automobile dynamic balance, and tire is caused the wearing and tearing of irreparability, and running car has vibrations and noise.
Another kind is that pneumatic tyre is repaired aerosol, when blowing out or boring a hole in the running car way, be evenly distributed on doughnut interior be charged gas and tire patching liquid ingredient, to carrying out tire patching; The condensation effect of this repairing method is non-constant also, adds the wood powder grain in leakage repairing agent, though improved certain wear resistance, serious flowability, the adhesive property of reducing causes the mending-leakage time long, and air pressure is not enough.
Summary of the invention
Technical problem to be solved by this invention is: tyres mending liquid bond effect of the prior art is poor, wears no resistance; Thereby provide a kind of novel, the automatic tire healant that bond effect is good, wear resisting property is good.
A kind of automatic tyre mending agent, it comprises air pressure agent, air pressure inhibitor, gelifying agent, rubber grain, fiber and solvent; Also comprise nano-carbon powder.
Automatic tyre mending agent provided by the invention, by adding nano-carbon powder, the bonding characteristic of puncture-mending agent has obtained enhancing, has reduced simultaneously the shrinking percentage of condensing of puncture-mending agent; Improved the tire crocking resistance, ageing-resistant performance, resistance to cleavage; And can not cause corrosion to tire.
Specific embodiment
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.

The mixed rubber particle of the optional natural rubber particle of rubber grain, paracril particle, styrene-butadiene rubber(SBR) grain or above rubber grain.Rubber grain of the present invention is preferably the styrene-butadiene rubber(SBR) particle; Add the styrene-butadiene rubber(SBR) particle, the ageing resistance of the tire that has added automatic tyre mending agent provided by the present invention, wear resistance are significantly strengthened.More preferably, the median size of styrene-butadiene rubber(SBR) particle is 0.5-1mm, and effect is better like this.
Fiber mainly improves mending-leakage place snappiness and wear resisting property, optional natural fiber (such as cotton fiber, xylon) or artificial fiber; The preferred artificial fiber of fiber of the present invention, the artificial fiber that is more preferably are polypropylene fibre; Adopt the polypropylene fibre can the aided nano carbon dust, improve the adhesive property of automatic tyre mending agent.
Nano-carbon powder of the present invention can the Effective Raise automatic tyre mending agent cohesiveness and wear resistance.The preferred nano-carbon powder of the present invention median size be 10-100nm, more preferably 20-30nm.The flowability that the nano-carbon powder of this particle diameter can make automatic tyre mending agent reduces the contraction of condensing more.
The present invention does not do particular requirement to the solvent of automatic tyre mending agent, as long as can dissolve the various solutes of automatic tyre mending agent; Solvent of the present invention is preferably deionized water.
In order to make automatic tyre mending agent have better effect, the present invention can also increase additive, and additive can contain sterilant, frostproofer.
Wherein sterilant can be inorganic fungicide, also can be organic bactericide, can also be natural bactericidal agent; Sterilant of the present invention is preferably organic bactericide, and the organic bactericide that is more preferably is vanillal; Sterilant of the present invention, antibiotic timeliness is long, easily disperses the quality guaranteed period that can improve automatic tyre mending agent, the out-of-service time of the automatic tyre mending agent that slows down.
Frostproofer can be ethylene glycol, also can be propylene glycol, can also be dme, and deicing fluid of the present invention is preferably propylene glycol; Adopt propylene glycol can guarantee that automatic tyre mending agent does not freeze phenomenon under-40 ℃ condition, can overcome the phenomenon that automatic tyre mending agent lost efficacy simultaneously under-40 ℃ condition.
Preferred its component of automatic tyre mending agent of the present invention and component content are as follows:
Air pressure agent 30-40wt%
Air pressure inhibitor 7-13wt%
Gelifying agent 10-15wt%
Nano-carbon powder 5-10wt%
Rubber grain 10-15wt%
Fiber 1-3wt%
Additive 8-9wt%
Solvent 5-25wt%.
Adopt the automatic tyre mending agent of above-mentioned prescription, properties all can reach higher level.
The present inventor is unexpected to be found, nano-carbon powder is joined in the automatic tyre mending agent, can make on the one hand puncture-mending agent at short notice the bonding action be finished at pertusate position, and bond effect improves greatly; Simultaneously can also reduce the contraction of condensing.Can improve on the other hand the wear resistance of tire, ageing resistance is largely increased, and the resistance to cleavage of tire also is improved, and automatic tyre mending agent of the present invention is to the tire non-corrosiveness.
The preparation method of automatic tyre mending agent of the present invention is known in those skilled in the art, and the present invention is preferably: solvent is poured in the container, then additive is poured into and mixed; To wherein adding rubber grain and fiber, be stirred well to Uniform Dispersion again; Then add air pressure agent, air pressure inhibitor and gelifying agent, and continue to stir; Add at last nano-carbon powder, be stirred to and be uniformly dispersed.
