Description
Technical field
The present invention relates to a kind of method of tyre rebuilding, belong to the technical field of rubber process.
Background technology
At present, presulfurization strip tyre surface that tyre rebuilding adopts and circular tread renovation method are progressively replacing traditional renovation method, but these renovation methods can only be renovated crown.Because the wearing and tearing and the degree of injury of old tire have nothing in common with each other, the old tire that has only need upgrade the tread rubber of wearing and tearing, what have then needs the belt place under repair, reinforcement or replacing, what also have need be to the sidewall place under repair, above-mentioned these renovate methods can only renovate tyre crown, the renewal tread rubber, change tread rubber and belt together, come to nothing for shoulder, the tire of sidewall damage and tyre bead damage then can't renovate, can not repair the belt of local damage, lack processing flexibility, but be difficult to adapt to the renovation requirement of different old tires and cause the refresh rate of old tire lower.And the anti-intensity difference that deflects of presulfurization strip tyre surface or circular tread and carcass junction, and tangible joint mark is arranged, thereby influenced the security reliability and the presentation quality of retreads.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing presulfurization strip tyre surface and circular tread tyre rebuilding method can only be renovated tyre crown, can not adapt to the renovation requirement of different old tires, but the refresh rate of old tire is lower, all drawbacks such as the low presentation quality difference of the security reliability of retreads.
Purpose of the present invention just provides a kind of method with segmented mold vulcanizer tire retreading, the demand that can adapt to the old tire renovation of various damages and wearing and tearing neatly, can renovate according to the different degree of injury position of old tire comprehensively, but improve the refresh rate of old tire and the security reliability and the presentation quality of retreads, and can reduce the tyre rebuilding cost.
For addressing the above problem, the present invention by the following technical solutions:
Described segmented mold vulcanizer tire retreading method, it is characterized in that: according to carrying out the tyre surface grinding or peel off belt or peel off the rubber at tire tire shoulder position in Tyte Wear, degree of injury and position, carcass is polished, make its rough surface, the brushing rubber cement, stick unvulcanized tread rubber or stick the kiss-coating all-steel cord, recover the intensity of belt, stick unvulcanized tread rubber according to degree of injury, the hole is hindered in repairing, vulcanizes in the vulcanizers with segmented mold that has tyre tread of packing into.
