Description
Technical field
The present invention relates to a kind of processing enhanced chemical binder scope, the enhanced chemical binder that is made by described method is used for self-service quick repairing car tire bundle hole and crack.
Background technology
Vehicle travels on the ground, the roller tire contacts with ground, tire and ground friction produce a large amount of heat, make the tire deliquescing, not only the oversize tyre wearing and tearing but also easily prick, explosive, the tire patching technology that is absolutely necessary, and existing traditional tire patching technology is by manual tire patching, and labour intensity is big, and the practicing engineer just can finish, automobile has spreaded all over huge numbers of families in China, and this situation is not suitable for the demand of social development very much.
The research of puncture-mending agent at home and abroad is not a lot, and a small amount of automobile-used tire patching product that can see in the market mainly contains two kinds in pulvis and aqua.The former is a raw material with starch, talcum powder, terra alba mainly, must allocate by water before using, and the tire patching weak effect is only kept several hrs.The latter is many to be raw material with Vinyl Acetate Copolymer, polyvinyl alcohol, light calcium carbonate, Mierocrystalline cellulose, xylogen, rubber grain, rubber powder etc.Their common deadly defects are, owing to still have the ND slit of naked eyes between the sealing agent particle, can not resemble close fusion traditional tire patching adhesive tape between the sealing agent particle and between sealing agent particle and the acanthopore, one integrated mass, under powerful tire pressure effect, still can cause slowly and leak, must inflate once again every several days.And all there is poor stability to some extent in existing puncture-mending agent, the shortcoming that the quality guaranteed period is short.
Summary of the invention
The present invention is directed to above shortcoming, succeed in developing and a kind ofly can overcome above-mentioned deficiency, stopping property and good stability, long-lived tyre mending glue.
Tyre mending glue of the present invention, be by following material by certainweight per-cent, and be made by certain technological process:
Deproteinization natural rubber latex 50～70%
Primitive fiber 1～5%
Ammonium hydroxide 0.01～0.5%
Glycerine 5～10%
Ethylene glycol 10～25%
Stablizer 0.1～0.5%
Rubber accelerator 0.1～0.5%
All the other are pure water
Contain 1～5% the protein of having an appointment in the natural rubber latex, if these protein are not removed, corruption takes place easily and make that latex lumps, the generation stench is rotten, badly influence the quality guaranteed period of the tyre mending glue of preparing, also be to cause one of reason of leaking slowly behind the tire patching, groups of people also can produce the contact allergy reaction, therefore must be removed.Remove method of protein in the latex and be add 0.001%～1% proteolytic enzyme in natural fresh latex, the treatment time is week a few hours to one, and usually conduct reached the effect of protein removal rate more than 90% in 24 hours.Treatment temp is 5 ℃～90 ℃, and optimum temperuture is 20 ℃～60 ℃.The temperature temperature surpasses 90 ℃, proteolytic enzyme meeting inactivation; Be lower than 5 ℃ then proteolytic enzyme can not bring into play the function of degrade proteins.Proteolytic enzyme can have multiple source, the proteolytic enzyme that derives from animal, plant and microorganism all can, but because the different amounts of adding of enzymic activity will be done corresponding adjustment.The most handy microbial protease during actual the use, its inexpensive and active height, and can also keep active for a long time, so unit cost to remove proteic effect best.
Proteic removal degree should reach the nitrogen content of Kjeldahl determination mensuration less than 0.1% in the latex, need add the protein-n decomposition accelerating agent about 5% when measuring with Kjeldahl determination, as copper sulfate, vitriolate of tartar, red precipitate etc., to impel nitrogen fully to decompose out, form ammonium sulfate, use the salt acidometric titration to determine protein content again.
The drc of Deproteinization latex should be between 55%～65%, and unnecessary moisture content can be removed with centrifuging.
After latex is handled through above-mentioned Deproteinization, add about 0.1～0.5% stablizer, as potassium rosinate, sodium abietate etc., also can be the Ester that contains carboxyl or sulfate group, and purpose is to avoid the latex polymerization caking.The adding of ammonium hydroxide not only can be regulated the pH value to alkalescence, stops microorganism to breed in latex and makes latex rotten, and it also has the effect that prevents the latex polymerization caking.But the addition of ammonium hydroxide to be being no more than 0.5% for good, if surpass then the tyre mending glue plugging time of preparation prolongs, but can not influence the effect of tire patching.
Ethylene glycol is a kind of frostproofer among the present invention, and addition can change with the requirement of product performance is different, and 10% addition can make tyre mending glue-20 ℃ of normal down uses, and 25% addition can make tyre mending glue normal use under-50 ℃.
The interpolation of rubber accelerator makes when tyre mending glue and acanthopore produce friction, glue particulate polymerization reaction take place and in the extremely short time tire acanthopore being blocked.Be no more than 0.5% thiuram (thiuram has another name called thiram) is advisable with adding.
Primitive fiber can make tyre mending glue and acanthopore produce blended polymkeric substance sprue when producing friction, increases the intensity of sprue and the time of using in tire, and add-on is between 1%～5%.The length of primitive fiber is 0.05～2.0mm, length-to-diameter ratio is 5～50, cut-out of making by following material or crushing fiber, for example, aromatic polyamide fibre, tynex, 1,6-capron(e), polybenzimidazole fibre, trevira etc., they can be scattered in equably in the glue and can not precipitate.
In the shelf life of products in 3 years, the phenomenon of rubber nature polymerization or ageing of rubber can not take place in the present invention, and therefore from the consideration that reduces cost, anti-aging agent can not add.Can certainly add 0.1～0.5% 2, the 6-di-tert-butyl methyl phenol is as anti-old, oxidation inhibitor.
The adding of glycerine mainly is to work aspect environmental protection except improving the resistance to frost among the present invention.The tyre mending glue that contains glycerine is just in case trickle down in environment, and insolation can not dried up or lump in 60 days yet under burning sun, is easy to be washed away by the rainwater dilution.
Tyre mending glue of the present invention is applicable to the rubber tyre of any vehicle, can inject in advance or inject during emergent the use in the tire (have tubeless all can), and can be in tire life-time service.
When tire is punctured gas leakage, need not to extract valve inside, as long as in the tire tonifying Qi, glue pump is being advanced in the tire, with tyre rotation one circle with miniature aerator pump, effect by the tire inner air pressure makes glue and acanthopore friction form micelle, acanthopore very can be blocked nearly to mend.This product is owing to use the natural rubber latex of Deproteinization and micro-fiber reinforced polymer to be main raw material, identical with tire character, thereby the bound energy of glue and acanthopore combines together, avoided the shortcoming that still can leak slowly behind the currently available products tire patching, but subzero 40 ℃ to 80 ℃ of life-time service above freezing.And it to harmless, nontoxic, the no burn into of tire do not fire, not explosion, the quality guaranteed period reaches 3 years, environmentally safe, use very convenient, anyone can both be in several minutes alone operation finish, but the life-span of significant prolongation tire.
