RU2331517C2 - Method of rubber product surface repair (versions) - Google Patents

Abstract

FIELD: technological processes.

SUBSTANCE: method of rubber product surface repair, which implies clearing damaged and adjacent surface, their deoiling, application of glue composition, dehumidifying, plaster application and its clamping down. Then cold or thermal vulcanisation is performed, as well as removing pimples. At that, outlet of accumulating gases is provided, for example, by drilling at least one hole, and damaged surface size is decreased by squeezing, wheel cage is rebuilt using cord plaster or raw rubber. the method of rubber product surface repair, which implies clearing damaged and adjacent surface, their deoiling, application of glue composition, dehumidifying, plaster application and its clamping down. Then cold or thermal vulcanisation is performed, as well as removing pimples. Damaged surface size is decreased by squeezing before glue composition application.

EFFECT: inventions allow to repair pneumatic tyre repair more accurately and to increase lifetime of repaired products.

Description

The claimed technical solution relates to the tire industry and is intended to repair local damage to pneumatic tires of various vehicles and other rubber products by vulcanization and can be used in the conditions of auto repair shops.

A known method of repairing surface defects of products RU 2214919 with a priority date of 08/17/2001, in which the damaged and nearby surfaces are cleaned, fix the device for pumping the repair composition, pump the repair composition into the defect cavity and heat it. Vibro-injection of the repair composition into the cavity of the defect is carried out with the simultaneous formation of the surface of the repair area.

The known method is not effective if the wheel casing is damaged, i.e. the integrity of the layers of rubberized fabric is broken and the cords are torn.

There is a known method of repairing a tire of a wheel, "Used car". E. Tsarev, Fedorov Corporation. Samara, 1996, p. 196, in which the damaged area to be repaired is cleaned of dust, dirt and dried. The inner surface of the tire around the damaged area is cleaned with a wire brush along the cord threads and smeared twice with rubber glue. After each coating, the glue is allowed to dry for 20 minutes. Before applying to the prepared area of the tire, the cuff (patch) is lubricated with glue and dried, then the applied cuff (patch) is tightly pressed to the tire with some heavy object.

The above method is not effective due to the fact that as a result of a chemical reaction that occurs when the patch and the tire are bonded, a gas is formed that provokes the formation of “hernias”, it is impossible to exploit the tire with such bloating, it can burst at any time.

The objective of the proposed technical solution is to eliminate the occurrence of marriage during the repair of surface defects of rubber products.

The problem is solved due to the fact that when repairing surface defects of rubber products, the damaged and surrounding surfaces are cleaned, degreased, the gases formed are removed by drilling at least one hole, the surface of the defect is reduced by compression, the adhesive is applied, and cord repair component through the use of a cord patch, and drilling is carried out in case of damage to the cord component.

The process of repairing defects in the surfaces of rubber products is as follows.

They clean the surface of the defect to a clean layer, degrease the surface with an organic solvent, if there is damage to the cord component, drill one or more holes if necessary, apply with a brush or trowel, glue, apply a cord patch, then carry out cold or thermal vulcanization. Then carry out the removal of sag and or bumps.

After the tire repair of the wheels of the vehicle and during further operation as a result of a chemical reaction that occurs during and after bonding the patch and the tire, gas is formed that exits through the drilled holes and prevents the formation of “hernias” and swelling, which extends the life of the tires.

If there is no damage to the cord component, the repair process is carried out as follows: they clean the surface of the defect to a clean layer, degrease the surface with an organic solvent to restore the original size at the place of the defect, because in the presence of a defect, surface stretching takes place, the surface being repaired is reduced by compression, for example, with a tourniquet, or with a hand, or by any other known method, glue is applied with a brush or spatula, a plaster or wet rubber is applied, cold or thermal vulcanization is carried out. Then carry out the removal of sag and or bumps.

Compression of the repaired surface is necessary to restore the original dimensions of the repaired surface.

The proposed method allows for better quality repair of rubber products in workshops and small production workshops, to increase the durability of repaired products.
