Description

A kind of autoinflation tyre-repairing liquid
Technical field
The present invention relates to a kind of automatic inflation, mending-leakage mixture that is used for rubber tyre, and preparation method thereof.
Background technology
The tire overwhelming majority that present stage uses is a pneumatic tyre, after being punctured by the nail on the road surface or hard thing, can cause and acutely lose heart, and the lighter is cast anchor, and weight person might cause overturning, causes the Serious Accident of car crash.Traditional puncture-mending agent will through unload wheel, take off tire, series of processes such as tire patching, formality is numerous and diverse, it is time-consuming to require great effort, and when driving a vehicle, does not possess the tire patching condition especially in the open air, tire is stung the back just can't be continued to travel at all.
In order to address the above problem, someone has invented tyre mending glue, and most polyvinyl acetate emulsion or polyvinyl alcohol solutions of adopting are equipped with starch, Mierocrystalline cellulose and mineral filler etc., the sealing composition is more single, and flowability, stability, oxidation-resistance and tackiness can not meet the demands.And be the simple tire patching function that has, add puncture-mending agent after, also need inflate.As Chinese patent 90109738.1, adopting natural and synthetic adhesive is base-material, has added various strengthening agents, anti-aging agent etc., has well improved tyres mending liquid stopping property and ageing-resistant performance.But adopt fibrous bundle and mineral filler to make supporting material, can solidify gradually, the wearing and tearing tire at tire inner wall.Some tyres mending liquid may contain acidic substance, it as application number 91104114.1 patent, the puncture-mending agent made from sheet rubber, lacquer thinner, gasoline, bluestone powder, white lime and sulfuric acid, though the tire patching effect is fine, but owing to contain sulfuric acid, the inner tube of a tyre or inflating valve etc. there is very strong corrosive nature, and is not suitable under the low temperature using.Adopt organic filler, can reduce the friction infringement to tire, adopt the natural rubber particle reinforcement harmless to tire as Chinese patent 96108493.6, energy and tire reach permanent healing.But natural rubber need soak in toluene when using, and makes its expansion softening, and tire can become fragile behind the toluene that absorbs micelle release, ftracture easily, moreover toluene is hazardous substance, is easy to blast.
In order to solve the problem of inflation simultaneously, someone has invented the tyre repair aerosol, and it can make very easily to break and become flat tire and mend rapidly, reaches inflation performance simultaneously, do not need to take off operations such as tire, directly tyres mending liquid is filled the tire agent along inflating valve and rotate several circles and get final product by propellent.But traditional tire patching aerosol, some can only make disappointing tire temporarily inflate, even also can cause chronic disappointing after for some time; Some freeze proof poor effect is as Chinese patent 92109046.3; Tire patching speed is slow; Propellent is flammable, and shortcoming such as perhaps damage the ozone layer is not widely used.
Summary of the invention
In order to overcome above-mentioned shortcoming, the purpose of this invention is to provide a kind of autoinflation tyre-repairing liquid, this tyres mending liquid has good resistant of high or low temperature, and is harmless to tire, environmental protection, the speed of making up automatically is fast, long quality-guarantee period, and have the characteristics of automatic inflation.
To achieve these goals, the present invention is by the following technical solutions:
A kind of autoinflation tyre-repairing liquid, form by the raw material of following weight part:
50~70 parts of natural rubber latexes
3~10 parts of emulsifying agents
10~20 parts of frostproofers
3~5 parts in tensio-active agent
0.3~1 part of stablizer
10~20 parts of distilled water
100 parts of propellents
Below technique scheme is done and specified.
Natural rubber latex has good film-forming properties, and good elasticity, mechanical stability are arranged after the film forming, is easy to block the hole, and good with tire adhesion force, to characteristics such as tire are harmless, plays the tire patching effect.
Emulsifying agent can keep latex particle not condense, and the emulsifying agent that the present invention adopts is a polyvinyl formal.Described polyvinyl formal can prepare by ordinary method, such as by the following method the preparation: get polyvinyl alcohol, hydrochloric acid, formaldehyde solution, sodium hydroxide solution and distilled water each some in reactor hybrid reaction make; As preferably, polyvinyl alcohol, hydrochloric acid mass concentration are 10%, formaldehyde quality solution is 37%, sodium hydroxide quality strength of solution is 10%, and the weight ratio of polyvinyl alcohol, hydrochloric acid, formaldehyde solution, sodium hydroxide solution, water is 12: 0.3: 10: 0.4: 77.3.
The effect of frostproofer is exactly the use temperature that reduces tyres mending liquid, and it still can normally be used at low temperatures, and the frostproofer that the present invention adopts is ethylene glycol, propylene glycol or glycol ether.
Tensio-active agent can foam, and helps the ejection of tyres mending liquid, can also play certain stabilization simultaneously, and the promoting agent that shows that the present invention adopts is sodium lauryl sulphate and Sodium dodecylbenzene sulfonate.
Stablizer stops polyvinyl formal to continue polymerization, keeps the stability of polyvinyl formal, and the stablizer that the present invention adopts is the mixture of diethylamine and quadrol.
That propellent adopts is fluorohydrocarbon propellent HFC-134a, because HFC-134a is not flammable, and does not have destruction to ozonosphere, sprays effective.
The preferred described autoinflation tyre-repairing liquid of the present invention is made by the feed composition of following weight part:
60 parts of natural rubber latexes
6 parts of emulsifying agents
Frostproofer 10-15 part
3~5 parts in tensio-active agent
Stablizer 0.5-1 part
10 parts of distilled water
100 parts of propellents
Wherein, described emulsifying agent is a polyvinyl formal, described frostproofer is ethylene glycol and propylene glycol according to mass ratio 5~10: 2~5 combination, described tensio-active agent is sodium lauryl sulphate and Sodium dodecylbenzene sulfonate according to mass ratio 2~3.5: 0~1.5 combination, described stablizer is diethylamine and quadrol according to mass ratio 0.3~0.5: 0.2~0.5 combination, described propellent are fluorohydrocarbon propellent HFC-134a.
The present invention also provides a kind of preparation method of autoinflation tyre-repairing liquid, may further comprise the steps:
A. under stirring at room, in reactor, add natural rubber latex, emulsifying agent successively, stirred 60~90 minutes;
B. in another reactor, add entry, frostproofer, stablizer, tensio-active agent, stirring at room 60~90 minutes;
C. the mixing of materials with step a and step b stirred 60~90 minutes, filtered; Mixed solution is filled in the can, charges into propellent, promptly obtain described autoinflation tyre-repairing liquid.
Further, what filter employing among the step c is 50~200 purpose acrylic fibers, filters out the big impurity of some particles, guarantees the ejection effect, in order to avoid block spout.The nozzle inside diameter of the can after the can is greater than 5mm, to guarantee inflating and tire-patching fast.
The inflating and tire-patching of car and all kinds of motorcycles was connected nozzle on the inflating valve during this product was applicable to, pressed lower cover, and automatic mending tyre liquid is punched into tire, wait to inflate saturated after, extract nozzle, finish inflating and tire-patching.Part tyres mending liquid is subjected to the thermosetting protective membrane attached on the tyre wall, and another part becomes mist, and after tire was punctured once more, film forming reached the tire patching effect once more, and validity period reached more than 6 months.
Compared with prior art, the invention has the advantages that:
The present invention adopts the natural concentrating glue breast as main raw material, cooperate multiple hosts such as frostproofer, whipping agent, stablizer, stopper, product cost is low, long quality-guarantee period, and validity period reaches 6 months, frost resistance is good, the low temperature of ability-20 ℃, spouting velocity is fast, and tire patching is effective, the preparation method is simple, and economic and social benefit is remarkable.
