Abstract
The invention relates to a used tire retreading method. The method comprises the following steps: selecting a tire body capable of being retreated; cutting and grinding the surface of the tire body; sewing a crack, and reinforcing the crack by utilizing a liner; smearing adhesive onto the tread under a vacuum state; press-fitting a tread adhesive strip onto the tread of the tire body; finally vulcanizing. The used tire retreading method has beneficial effects that by adopting the retreading method, the waste of resource is greatly reduced, the retreaded tire is good in quality, high in balance quality and low in flat tire rate, the tire body is subject to high temperature and high pressure in the retreading process, factors causing the aging of the tire body can be reduced, the retreading times of the tire body can be increased, and the service life of the tire body can be prolonged.
Description
Technical field
The present invention relates to a kind of old tire renovate method.
Background technology
Along with the continuous growth of China's economy, road car carries a large amount of shipping tasks.Along with the sustainable growth of automobile pollution, use amount and the consumption of automobile tire also increase thereupon fast, for the recycling of carcass, not only can save a large amount of rubber and metals resources, and the environmental pollution that tire waste gas can also be avoided to cause, there is extremely huge economic and social benefit.At present, automobile tire generally, after damage, except can repairing, all again can only be changed, and the discarded one side of junked tire be caused to the waste of resource, also result in the pollution of environment on the other hand.Under existing tyre retreading technique, the tire that can reach renovation standard is fewer and feweri, causes a large amount of tire to discard, and the tyre explosion rate of renovation is high reluctantly, and balance is poor, and difficult quality controls, threat to life safety.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of old tire renovate method, adopt the tire quality after the method renovation good, balance is high, long service life.
The present invention is achieved by the following measures:
A kind of old tire renovate method of the present invention, comprises the following steps:
Step 1, filters out the carcass that can carry out renovating;
Step 2, cuts polishing to carcass surface, removes surface aging glue-line;
Step 3, inserts middle pad glue, is sewed up by breach in the hole on tyre surface, and pads glue in suture is filled, and the suture liner inside tyre surface carries out reinforcement;
Step 4, cleans the carcass after processing through step 3, drains the moisture remained on carcass with vacuum plant, and on tyre surface, sprays adhesive glue under vacuum conditions;
Step 5, carries out presulfurization process by the tread rubber strip form mated with carcass, is then pressed together on the tyre surface of carcass by tread rubber strip form;
Step 6, envelope on the carcass cover after step 5 is processed, and load onto the inner tube of a tyre, rim strip and wheel, this tire assembly is sent in vulcanizing tank and carries out sulfuration, make tyre surface, liner and tread rubber strip form strong bonded.
In steps of 5, the temperature that tread rubber strip form carries out presulfurization process is 3-10 DEG C, and sulfide stress is 17 ~ 20 bar, and tire assembly carries out the temperature of sulfuration is in step 6 95-110 DEG C, and sulfide stress is 5.5 ~ 7.8 bar.
In step 3, the middle pad glue temperature of filling is 65 DEG C ~ 88 DEG C, fills in latter 72 hours and carries out sulfuration.
The invention has the beneficial effects as follows: adopt renovate method of the present invention, greatly reduce the waste of resource, and quality is good after tyre rebuilding, balance is high, rate of blowing out is low, and in refurbishment process, carcass is without undergoing HTHP, decreases the factor causing carcass aging, add the renovated number of times of carcass, extend the service life of carcass.
Detailed description of the invention
A kind of old tire renovate method of the present invention, comprises the following steps:
(1) carcass that can carry out renovating, is filtered out; Tyre inspection machine can be adopted to check the damage of old tire, aging and abrasion situation, also can manually check.
(2), polishing is cut to carcass surface, remove surface aging glue-line; By tyre crown grinding
To certain size, to remove stained tyre surface.
(3), insert middle pad glue, sewed up by breach in the hole on tyre surface, and pad glue in suture is filled, the suture liner inside tyre surface carries out reinforcement; Hole on tyre surface is blocked, and crack is sewed up.Carry out preliminary repairing.
(4), the carcass after processing through step 3 is cleaned, drain the moisture remained on carcass with vacuum plant, and on tyre surface, spray adhesive glue under vacuum conditions; Under vacuum conditions, reduce dust on the one hand to the impact of adhesive glue, reduce the bubble that adhesive glue produces in spraying process on the other hand, greatly improve the effect of bonding.
(5), the tread rubber strip form mated with carcass is carried out presulfurization process, then tread rubber strip form is pressed together on the tyre surface of carcass; By envelope on the carcass cover after process, and load onto the inner tube of a tyre, rim strip and wheel, this tire assembly is sent in vulcanizing tank and carries out sulfuration, make tyre surface, liner and tread rubber strip form strong bonded.
The temperature that tread rubber strip form carries out presulfurization process is 3-10 DEG C, and sulfide stress is 17 ~ 20 bar, and the temperature that tire assembly carries out sulfuration is 95-110 DEG C, and sulfide stress is 5.5 ~ 7.8 bar.Adopt cryogenic vulcanization, make carcass without undergoing HTHP, decrease the factor causing carcass aging, add the renovated number of times of carcass, extend the service life of carcass.Through repeatedly testing, the middle pad glue temperature of Temperature Fill is 65 DEG C ~ 88 DEG C, fills in latter 72 hours and carries out sulfuration.
The above is only the preferred embodiment of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
