Abstract

The invention provides a preparation method for improving production security of a tire curing bladder, and relates to the technical field of the curing bladder. The curing bladder takes butyl rubberand chloroprene rubber as the basic rubber; compared with the prior art, an anti-scorching agent is added, the adding of the anti-scorching agent can prolong the scorching time, thereby ensuring thatthe mold filling is incomplete and a nozzle cannot be blocked in the injection; and meanwhile, the optimum curing time is prolonged, the production efficiency is reduced, other process is appropriately adjusted, such as the adding amount of the curing temperature of the active agent zinc oxide and promoter DM; the prepared tire curing bladder can realize the appropriate total curing time when reaching a basic performance requirement, the scorching time is prolonged, and the production security is improved.

Description

technical field [0001] The invention relates to the field of vulcanization bladder production, in particular to a preparation method for improving the production safety of tire vulcanization bladders. Background technique [0002] The tire curing bladder is a very important link in the tire curing process. The quality of the tire curing bladder directly affects the quality of the tire. Due to the conditions required during the use of the vulcanizing bladder, the selection of rubber is very strict, requiring that the rubber must be able to be used in an environment of high temperature, high humidity and high pressure for a long time. The main material of the tire curing bladder is butyl rubber, which has high saturation and slow vulcanization speed; in order to improve production efficiency, it is necessary to shorten the vulcanization time, and the shortening of the vulcanization time will shorten the scorch time and cause nozzles to appear The phenomenon of blockage will c...
