Abstract

The invention relates to a tire bladder anti-adhesive agent, which is a two-component tire bladder anti-adhesive agent, wherein component A emulsion mainly comprises hydroxyl dimethylsiloxane; component B emulsion mainly comprises poly(methylhydrosiloxane); and the tire bladder anti-adhesive agent also comprises an emulsifying agent, a defoaming agent, a bactericide deionized water. The tire bladder anti-adhesive agent can be used for spraying the inner surface of a green tire, and also can be directly used as a coating layer on a bladder. The tire bladder anti-adhesive agent provides good demolding property, lubricating property and exhausting property between the bladder and the tire, prolongs the service life of the bladder, makes the appearance of the tire smooth, prevents a mold from being polluted, does not contain any volatile organic matters, and reduces environmental pollution.

Description

technical field [0001] The invention relates to a two-component tire bladder release agent. Background technique [0002] Isolation lubrication systems play a constant, yet very important role in the tire manufacturing industry. Usually, the isolation lubrication system of tires includes three parts: inner spray agent, outer spray agent and bladder release agent which play the role of lubrication, mold release and isolation in tire vulcanization. Usually borne by substances that improve the fluidity and release properties of the compound during vulcanization. It is required to have a certain thermal stability and chemical inertness, not to corrode the surface of the mold, not to leave decomposition products on the surface of the mold, to give the vulcanized tire a good appearance, not to affect the surface color and aging resistance of the tire, and to be non-toxic. [0003] During the vulcanization process of the bladder, it is inevitable to experience various damages suc...
