Abstract

The invention discloses a preparation method of an ageing-resistant tire curing bladder, and belongs to the technical field of tires. The method comprises the following steps: a first step: preparing the modified natural rubber; a second step, taking chlorinated butyl rubber, modified natural rubber, N220 carbon black, N550 carbon black, an accelerant, zinc oxide, stearic acid, castor oil, magnesium oxide, nanometer silicon dioxide, an anti-ageing agent and stannous chloride in part by weight, and placing in an open mill to mix, wherein the mixing temperature is 90-125 DEG C and the time is 20-30 min; extruding rubber sheet through an extruder; a third step, carrying out an injection curing process. The preparation method of the ageing-resistant tire curing bladder provided by the invention is capable of improving the corresponding physical performances of the tier curing bladder; and meanwhile, the ageing resistance is excellent, and the tire can be used for a long time under harsh environment.

Description

technical field [0001] The invention discloses a preparation method of an aging-resistant tire curing bladder, which belongs to the technical field of tires. Background technique [0002] With the development of related technologies in the field of tires, tire technology has made great progress in terms of raw materials and processes, and continues to meet people's requirements for tire performance. [0003] In terms of raw materials, tire materials have become more and more abundant, and various functional materials can be reflected in tire technology; Process controllability is getting higher and higher. [0004] In all tire manufacturing processes, the vulcanization process is a very important step. After the tire is vulcanized, its performance is greatly improved. The tire curing bladder is just a tool for tire vulcanization and an important mold in the tire preparation process. The existing tire vulcanization bladders are mainly made of synthetic rubber, among which ...
