Abstract
The present invention relates to tyre repair field, in particular to a kind of pure solid-state original position self-repairing tyre nano repairing liquid.The main problem of solution be can in -200 ° ~ 100 ° temperature ranges normal use, there is long service life, feature at low cost, light-weight, meet tire weight and in terms of requirement, avoid performance loss and ride comfort from declining.The tire selfreparing nano repairing liquid can implement auto-mending to puncture tire, to prevent in tire high-speed cruising (200km/h), due to tire wear or pierce through the gas leak phenomenon of blowing out caused, effectively reduce the maintenance cost and traffic accident of automobile.
Description
Technical field
The present invention relates to tyre repair agent fields, more particularly to a kind of tire nano repairing with self-repair function
Liquid.
Background technique
Automobile largely because of tire wear and pierces through the quick-fried of initiation as the modern times most commonly used vehicles, annual generation
The traffic accidents such as tire.For the consideration to vehicle driving safety, anti-pricked tyre self repairing agent early has exploitation.Traditional tire is repaired
Tonic can be divided into pure solid filler, liquid phase reparation and embedded one layer of anti-puncture fiber etc., and main problem includes: that resonance is obvious
Ride comfort is influenced, vehicle body is uneven, and the renovation agent service life is short normally to play function under the conditions of extreme (high temperature, low temperature)
Effect, vehicle body weight gain obviously increases energy consumption, at high cost etc..Similar products majority is liquid form product at present, or needs 200 ° of height
Temperature solidification, and can only guarantee to travel 50-1000km after piercing, tire patching as early as possible is then just needed, is not certainly fundamentally
Repair the intellectual product of type.
Therefore the main problem that solves of the present invention is to design a kind of normal use to have and make for a long time under extreme conditions
Tonic is reviewed one's lessons by oneself with the light-duty pure solid-state low cost tire nanometer in situ in service life.The product is all solid state product, will not be because of centrifugation
Power causes tire deviation of gravity center, while guaranteeing that product can use steadily in the long term, using polymer composite, in conventional tyre
Inside, water suction crosslinking are squeegeeed, and the colloid bonded is laminated and is bonded in the inner surface of tire, once water suction cross-linked layer encounters
Micro water source (injection) expands rapidly, and forms gel, and under the auxiliary of tire pressure, moment fills up puncture and damaged part.
Maximum feature of the invention is using main body of the polyurethane rigid foam material as selfreparing intellectual material.Its feature
Are as follows: hole-closing structure has that insulation effect is good, light-weight, specific strength is big, the good characteristics such as easy for construction, at the same also have sound insulation,
The features such as shockproof, electrical isolation, heat-resisting (100 °), cold-resistant (- 200 °), solvent resistant.The present invention is exactly the spy using hard polyurethane foam
Point, in the case where puncture, moment leak repairing.And it can repeatedly leak repairing repeatedly.To reach the requirement intelligently repaired.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of tire nano repairing liquid with self-repair function, can
It prevents because of tire wear or pierces through the gas leak phenomenon of blowing out caused, effectively reduce the maintenance cost of automobile and the hair of traffic accident
It is raw.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: it provides a kind of with self-repair function
Tire nano repairing liquid, be coated in inside tires.It is punctured when encountering, under the action of internal pressure, rapid leak repairing prevents gas leakage.
It is made of following raw material: initiator, foaming agent, catalyst, foaming stabiliser, polyurethane, industrial rubber adhesive, nano material
Composition.The initiator is polyether polyol, and hydroxyl value is in 430 ~ 450mgKOH/g.The foaming agent is pentamethylene, one
Fluorine dichloroethanes and distillation aqueous mixtures.Its weight proportion of the pentamethylene is 10-15, its is heavy for a fluorine dichloroethanes
Amount proportion is 0-15, its weight proportion of the distilled water is 1.0-2.0.The catalyst is tertiary amine, and weight proportion is
1.0-2.5.The foaming stabiliser is the more alkoxy ether copolymers of polysiloxanes-.Its nco index of the polyurethane is
1.10-1.15.Described its weight proportion of industrial rubber adhesive is 15-30.The nano material is carbon nanotube, nanometer
At least one of silica or nano-titanium dioxide.The described carbon nanotube diameter 10-20 nm, 20-100 μm of length,
Weight proportion is 0.2-0.5；Nano silica partial size is in ± 30 nm of 50 nm, weight proportion 0.1-0.3；Nano-silica
Change titanium partial size in ± 30 nm of 50 nm, rutile-type, weight proportion 0.1-0.3.The nano material need to meet water solubility
Or oil-soluble requirement.
The beneficial effects of the present invention are: the pure solid-state of the present invention, avoids driving comfort sense caused by centrifugal force from declining.Using temperature
It is wide (- 200 ° -100 °) to spend range.It is light-weight, it avoids increasing and be self-possessed, oil consumption.Moment repairing, can Reusability, can replace completely
For spare tyre.
The present invention includes applications to nanostructures, to improve the performance of tyre repair agent.
Carbon nanotube has similar high molecular structure and main component is carbon, can shape with high molecular material compound tense
At complete combination interface, the composite material being had excellent performance shows fabulous intensity, anti-fatigue performance, antistatic property.
And nano silica is as reinforcing agent, it is only necessary to added in renovation agent it is a small amount of, the intensity of product, wearability and
Ageing resistance etc. can be obviously improved.Meanwhile intensity, toughness and waterproof performance and anti-aging property also obviously mention
It is high.
Nano-titanium dioxide is rutile-type fluffy white powder, has good dispersibility and weatherability, because its is huge
Specific surface area, good chemical stability, the use that renovation agent can be made stable for a long time.
Specific embodiment
The preferred embodiments of the present invention will be described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that so as to make a clearer definition of the protection scope of the present invention.
