Abstract
The invention discloses a method for recapping tyres of cars. The method comprises the following steps: selecting, cleaning and drying an old tyre of a car; carrying out processing, burnishing, moulding and typing on the tyre; fixing the tyre on a steel mould for aeration settling; carrying out high-temperature press vulcanization on the tyre in a rubber tyre vulcanizing boiler; and carrying out detection and shaving on the tyre out of the boiler. The method for recapping tyres of cars has few, simple and easy operation steps, little investment and easy industrialized production, thereby having good economic benefit prospects. The recapped tyre has the advantages that the types are various and the use range is wider; tackless does not exist during the use, thereby the tyre is very safe; the tire tread is wearable, thereby the tyre has long service life which is over two times that of other recapped tyres by comparison; and at the same time, the recapping of tyres effectively reduces environmental pollution, thereby having excellent economic and social benefits. The recapped tyre totally accords with quality requirements when being tested by an authoritative quality testing department.
Description
Technical field
The present invention relates to a kind of method of old tire renovation, be specifically related to a kind of method of recapping tyres of cars.
Background technology
Along with rapid economy development, the owning amount of private car is also increasing, and the quantity of the tyres for passenger cars that scrap the every year that thereupon brings is also very surprising.In these old tires, it is treadwear and blowing out that a less part is arranged, and wherein major part all is that carcass is good substantially.This part tire not only can cause environmental pollution if abandon arbitrarily, causes the wasting of resources especially.At present, in the repeated use for old tire, tyre rebuilding is comparatively common, use therein method have old tire again embossing and elevated temperature heat turn over method etc., these methods are because operating procedure is many, the input cost height, the tire wear that produces is poor, easily come unglued, shortcoming such as security performance is low, and be eliminated gradually.Do not have method for renovating tyre preferably, directly cause China's junked tire refresh rate very low, the old tire that carcass is intact fails to be fully used.
Summary of the invention
Goal of the invention: at above shortcomings in the prior art, provide a kind of method of recapping tyres of cars during purpose of the present invention, to realize utilizing renovate method simple to operate, the equipment less investment to renovate out solid durable high-quality tyres for passenger cars.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution used in the present invention is as follows:
A kind of method of recapping tyres of cars may further comprise the steps:
(1) chooses the car old tire of used suitable renovation, clean drying, and inflate check;
(2) tyre surface of the tire after handling through step (1) is processed grinding process, on the carcass of tire, carry out moulding, aeration settling after finishing;
(3) tire after step (2) processing is fixed on the steel mold, carries out aeration settling;
(4) tire of step (3) is put into the sulfurizing rubber tyre jar and carry out the high-temperature pressurizing vulcanizing treatment at first, in jar,, during to 25～33min, make a jar internal pressure reach 3.8～4.2kgf/cm with inner tube of a tyre inflation pressurization
2, interior tire pressure reaches 4.2～4.5kgf/cm
2, make inner tube of a tyre typing; Continuation is inflated to 38～42min with the inner tube of a tyre in jar, make a jar internal pressure reach 4.7～4.9kgf/cm
2, temperature is 77～83 ℃, outside envelope begins inflation; Continue to be inflated to 75～80min, make a jar internal gas pressure reach 5.6～6.8kgf/cm
2, inner tube of a tyre typing pressure reaches 5.8kgf/cm
2, outside envelope reaches 4.0kgf/cm
2, 105～110 ℃ of temperature controls; When continuing to be inflated to 98～102min, 118～125 ℃ of temperature controls, constant temperature sulfuration 200～210min; At last, 105～120 ℃ of temperature controls behind maintenance 60～70min, go out jar; Wherein, duration of work keeps every pressure stability.
(5) detect and repair and get final product going out tire behind the jar.
Wherein, in the step (1), the blowing pressure that inflation detects is 4.0～4.2kgf/cm
2In the step (2), described moulding is for pressing tread rubber, prevulcanized tire tread rubber or adhesive glue.Aeration settling is for to carry out aeration settling by mould.In the step (3), aeration settling is for to carry out aeration settling by mould.In the step (5), described detection comprises that inflation detects, and the blowing pressure is 4.0～4.2kgf/cm
2
For the technology that tyres for passenger cars renovates, topmost technical problem is exactly the sulfurization technology of tire, technical parameter wherein, for example: pressure, time and temperature etc., the direct renovation quality of decision tire, to the safe handling of later retreads and service life decisive role.The present invention is through groping for a long time and studying, developed characteristic tyre retreading technique, regulate and controlled pressure by continuous in this technology, the parameter of temperature and time reaches better cure efficiency, wherein, controlled pressure comprises tire pressure in the control, outside envelope pressure and jar internal pressure, tire pressure and jar internal pressure made to have good quality by retreads of the present invention in outside envelope pressure was lower than.
Beneficial effect: the method for recapping tyres of cars of the present invention, operating procedure is few, and is simple, the equipment less investment, therefore suitability for industrialized production has the good economic benefits prospect easily.The prepared car retreads that go out, mode is various, and use face is wider; Do not come unglued in the use, fool proof; Tyre surface is wear-resisting, and long service life is compared with other retreads, and the life-span will be grown more than 1 times; Simultaneously, tyre rebuilding effectively reduces environmental pollution, has excellent economic and social benefit.The retreads of this method manufacturing detect through national rubber tyre quality supervision and test center, and quality meets the requirements fully; Wherein, the high speed performance index of renovation sedan car radial ply tubeless tyre is by the check of GB/T7034-1998, and retreads (radial) are by the high speed performance check of GB14646-93.
