The invention discloses a preparation process of tire vulcanization bladder, which comprises the following steps: S1, internal mixing to prepare modified chlorinated butyl rubber; S2, open mixing to prepare mixed rubber, adding Eucommia rubber into the formula; S3, mixing The mixed rubber in step S2 is put into a rubber filter for filtration, and the rubber filter head is provided with a flat discharge port, and the mixed rubber is directly discharged through the discharge port to obtain a film; S4, injection vulcanization to obtain a tire vulcanization bladder . The invention modifies the chlorinated butyl rubber, and adds Eucommia rubber during kneading in an open mill, so as to improve the mechanical properties of the tire curing bladder and prolong the service life of the curing bladder; The design can be pressed while filtering, which improves the quality of the film and improves the work efficiency. |
