Method and equipment for vulcanizing waste tires with low energy consumption and under normal pressure

Abstract

The invention discloses a method and equipment for vulcanizing waste tires with low energy consumption and under normal pressure. The method comprises the following steps: firstly dissolving crude rubber by gasoline so as to obtain bonding agents; grinding to-be-repaired tires, cleaning broken pieces, smearing the bonding agents on wounds, and pasting crude rubber sheets; then putting inner tires into outer tires as support bodies, controlling the pressure of the inner tires to be 0.3-0.4MPa; pressing the crude rubber sheets pasted on the wounds; putting the tires into seal heat insulation layers, introducing steam to generate heat energy; treating at constant temperature for 8-10 hours in the seal heat insulation layers under the effect of steam of 70-80 DEG C; carrying out chemical reaction on crude rubber pasted on the tire wounds, bonding the crude rubber together with rubber of tires under the effect of internal pressure so as to repair waste tires. Fuels required by a normal-pressure boiler are low in price. The method is easy to operate, is high in speed, and has no safety hazard; the integral processing cost is reduced greatly; processed tires have no obvious reparation marks; the repaired parts cannot be damaged for the second time.

Description

[0001] technical field [0002] The invention relates to the technical field of automobile tire maintenance, in particular to a method and equipment for treating waste tires with low energy consumption and normal pressure heat repair. Background technique [0003] Under the mine working environment, the tires of mine cars are seriously damaged due to poor road conditions, especially when the speed exceeds 35km / h. A considerable proportion of the outer tires can be reused, and timely disposal of tires on the spot not only greatly improves the vehicle attendance rate, but also It also reduces operating costs, reduces scrapping and environmental pollution caused by tire retreading. And existing scrap tire repair method, mainly contains three kinds such as binding glue method (adhesive strip tire repair technology), cold subsidy sheet method, hot repair method. The glue binding method is only suitable for repairing the crown of steel wire radial tires. It has high requirements ...

AI Technical Summary

Problems solved by technology

The glue binding method is only suitable for repairing the crown of steel wire radial tires. It has high requirements for the rubber strip and has a narrow scope of application. The cold patch method can easily cause damage to the tire mouth steel wire during the loading and unloading of the tire. It is not durable, and after a period of water immersion Or when the driving speed is too fast, air leakage is likely to occur at the repaired place; the hot patching method has a wide range of applications, but it has high requirements for technical operations and site conditions, and a baking machine is required to bake the wound. Reasonable, it is likely to scorch the tires of the car, and even cause deformation in severe cases. The maintenance process lacks safety design and high cost, so it is not suitable for large-scale promotion

[0004] To sum up, the current processing technology for waste tires has its own defects, there are safety hazards and limitations, and the processing cost is high
