Description

Technical Field

[0001] The utility model relates to the technical field of tire bladder repair, in particular to a defect repairing machine for a vulcanized tire bladder. Background Art

[0002] The tire bladder is a rubber bladder that contacts the inner surface of the green tire during tire production. It is a tool for tire vulcanization processing, equivalent to the inner mold of the tire mold, and is made of butyl rubber. Tire bladders are divided into different models according to the different vulcanizers and fixtures. Their main function is to fill the tire with compressed air, nitrogen or hot water during the tire vulcanization process. The damage of tire bladders is generally divided into aging, soft holes and falling blocks. Among them, the defects caused by falling blocks can be repaired, which increases the number of uses of tire bladders and reduces the production cost of tires.

[0003] Among them, the "a kind of repair mortar for tire vulcanization bladder and its preparation and use method" disclosed in the application number "CN202111487668.X" "comprises the following steps: step S100, natural attapulgite is washed to obtain clean attapulgite; step S200, bisphenol A epoxy resin and diisocyanate are reacted to obtain isocyanate-modified epoxy resin; step S300, isocyanate-modified epoxy resin is mixed with clean attapulgite to obtain attapulgite / epoxy resin composite particles; step S400, halogenated rubber, attapulgite / epoxy resin composite particles, hexagonal boron nitride, and sulfur are mixed to obtain mixed rubber; step S500, alicyclic polyol, alicyclic polyacid and diisocyanate are reacted to obtain polyurethane prepolymer; step S600, mixed rubber, ethyl acetate and polyurethane prepolymer are mixed to obtain repair mortar. The repair mortar provided by the present invention has high bonding strength, good high temperature resistance, good toughness and good thermal conductivity."

[0004] However, the above method still has the following defects: when repairing the tire bladder, the repair glue is applied to the surface of the repair film and the vulcanization bladder to be repaired, the repair film is adhered to the vulcanization bladder after the solvent evaporates, and then vulcanized and bonded at 150-160°C to complete the repair.
