Abstract

The invention discloses a kind of production technology of trouble-proof tire, including step 1), the fixations of carcass;Step 2), the spraying of selfreparing sealant;Step 3), the anti-melting for piercing through sealant, poly- glue;Step 4), the glue spraying for piercing through sealant anti-for the first time;Step 5), second of anti-glue spraying for piercing through sealant.The present invention increases by one layer of toughness on the surface layer of anti-stab sealant and preferably prevents wearing sealant, after being applied on tire, when tire is punctured by sharp objects such as nails, anti-stab sealant is punctured, and prevent wearing sealant since its stronger toughness is without being punctured, after the sharp objects such as nail are extracted, anti-stab sealant can repair the place punctured, prevent its gas leakage, when encounter weather turn it is cool when, even if anti-stab sealant is reduced because expanding with heat and contract with cold, the hole punctured is caused to expose again, wears sealant by anti-and can also prevent gas leakage.

Description

A kind of production technology of trouble-proof tire
Technical field
The present invention relates to tyre technology more particularly to a kind of production technologies of trouble-proof tire.
Background technique
By thermoplastic elastomer (TPE) and modified tacky resin, liquid plasticizer, anti-aging agent etc. mixes under 170-220 degrees Celsius It closes, its sticky mixture is sprayed on tire inner surface under 170-220 degrees Celsius and pressure with high-temperature resistant pump, is made Anti-pricked tire.It is Chinese patent CN1303409A that its is representative, by SBS thermoplastic elastomer (TPE) and a certain amount of adhesive, Its fluid is coated in tire inner surface under 200-250 degrees Celsius by the mixing such as liquid plasticizer, and anti-pricked safety is made Tire.
The prior art is in order to enable anti-pricked tire sealant to be uniformly applied to tire inner surface, using heat molten type High molecular material.These materials are the soft elastomer material with tack at normal temperature, and at 80 degrees Celsius or more, it begins to Soften, loses intensity, 120 or more degrees Celsius, so that it may become the viscous liquid that can be trickled.The liquid is easy with coating In tire inner surface.
During galloping, or under hot weather, the temperature of automobile tire easily reaches or is more than 110 degrees Celsius.Trickling will be generated in inside tires using anti-pricked tire sealant manufactured by the prior art, not only make to take turns Tire loses anti-pricked function, and destroys the dynamic balancing of tire, makes automobile that can not run at high speed.
In view of the above-mentioned problems, Chinese patent CN103374311B provides a kind of reactive anti-pricked tire sealant, i.e., Make at a higher temperature, will not melt, however, the tire produced using the reactivity anti-pricked tire sealant, is passed through Be used for a long time discovery, after tire was pricked, although being automatically repaired by sealant, will not gas leakage, weather turn it is cool with Afterwards, sealant can be shunk, and pricked the hole left later originally and exposed again, will lead to have a flat tire in this way.

Selfreparing sealant is sprayed on the inner surface of carcass by step b) by the first spray gun, is carried out for the first time certainly The glue spraying of sealant is repaired, 50 ± 10 DEG C are cooled to after the completion of glue spraying;
Selfreparing sealant is sprayed on the inner surface of carcass by step c) again by the first spray gun, carries out second The glue spraying of secondary selfreparing sealant, glue spraying are cooled to 50 ± 10 DEG C after the completion.
Anti- puncture sealant is put into heating melting in the second rubber melting cylinder by step 3), the poly- packing element of feeding second after melting In stir evenly, the anti-puncture sealant in the second poly- packing element is sent into the second spray gun under the driving that second gear pumps, The temperature control of second rubber melting cylinder at 200 ± 10 DEG C, the temperature control of the second poly- packing element at 185 ± 10 DEG C, second gear pump and The temperature of second spray gun is controlled at 190 ± 5 DEG C;
Anti- puncture sealant is sprayed on the inner surface of carcass by step 4) by the second spray gun, is carried out anti-for the first time The glue spraying of sealant is pierced through, 50 ± 10 DEG C are cooled to after the completion of glue spraying;
Anti- puncture sealant is sprayed on the inner surface of carcass by step 5) again by the second spray gun, carries out second The secondary anti-glue spraying for piercing through sealant, glue spraying is cooled to 50 ± 10 DEG C after the completion, to obtain finished product.
Include carcass using trouble-proof tire made from above-mentioned technique, and is successively sprayed on surface layer on the inside of carcass Selfreparing sealant and anti-puncture sealant.
Meanwhile the present invention also provides a kind of anti-puncture film of high intensity, including selfreparing sealant and anti-puncture sealant, The anti-puncture sealant is located at the inside surface layer of selfreparing sealant.
Preferably, the anti-puncture sealant is fixed to the inside table of selfreparing sealant by the way of spraying Layer.
Preferably, the selfreparing sealant with a thickness of 1.5-2cm, it is described it is anti-pierce through sealant with a thickness of 2- 4mm。
Preferably, the anti-puncture sealant is viscoelastic material.
Preferably, the viscoelastic material the preparation method comprises the following steps: polyurethane, aliphatic diisocyanate, surface is living Property agent, silver nitrate, deionized water and ethylene glycol mixed dissolution, the lower 100 DEG C of reactions 6-8h of acid condition.
Preferably, the content of aliphatic diisocyanate is 10-20%, surfactant in the viscoelastic material Content is 0.8-3.6%, the content of silver nitrate is 0.3-1.6%, remaining is polyurethane.
Preferably, the selfreparing sealant is reactive anti-pricked tire sealant.
The present invention increases the preferably anti-puncture sealant of one layer of toughness on the surface layer of selfreparing sealant, is being applied to tire After upper, when tire is punctured by sharp objects such as nails, selfreparing sealant is punctured, and anti-puncture sealant is stronger due to it Toughness without being punctured, when the sharp objects such as nail extract after, selfreparing sealant can repair the place punctured It is multiple, its gas leakage is prevented, when encountering weather and turning cool, even if selfreparing sealant is reduced because expanding with heat and contract with cold, leads to the hole punctured Gap exposes again, can also prevent gas leakage by anti-puncture sealant.
