Title:
METHOD FOR PREPARING TIRE CURING BLADDER
Document Type and Number:
WIPO Patent Application WO/2021/114399
Kind Code:
A1
Abstract:
The present invention discloses a method for preparing a tire curing bladder, and relates to the technical field of tire curing bladder preparation. In the method for preparing a tire curing bladder in the present invention, raw materials comprise: 80-100 parts of a butyl rubber, 1-20 parts of a modified waste tire curing bladder material, 20-50 parts of carbon black, 8-10 parts of a vulcanized resin, 5.5-7.5 parts of castor oil, 2-4 parts of zinc oxide, 1-3 parts of stearic acid, and 3-5 parts of an accelerator. The preparation method comprises firstly carrying out a blending desulfurization and blending activation two-step modification treatment on the waste tire curing bladder material, and then carrying out internal mixing, mixing, injection and vulcanization on the waste tire curing bladder material and butyl rubber, so as to produce a new tire curing bladder. Compared with the prior art, in the present invention, the waste tire curing bladder is subjected to a modification treatment and then is applied to tire curing bladder processing again, and practice shows that the number of uses of the newly-manufactured tire curing bladder can reach 300-500 times.
