Abstract

The present invention relates to the technical field of auxiliary agents for vulcanization capsules, in particular to an adhesion promoter for vulcanization capsules and a preparation method thereof, an adhesion promoter for vulcanization capsules, and the adhesion promoter for vulcanization capsules is a core-shell structure, the core body is modified zinc oxide / attapulgite composite, and the shell is liquid butadiene rubber grafted with maleic anhydride; zinc oxide accounts for (35-40) wt% of the total amount of the core body; maleic anhydride It accounts for (17-25) wt% of the total amount of the shell; and the shell accounts for (60-65) wt% of the total amount of the adhesion promoter for the vulcanization bladder. The adhesive for vulcanization bladder provided by the present invention has good dispersibility and reinforcing effect in butyl rubber, reduces production cost, can improve the adhesion between butyl rubber, fiber filler and various processing aids, greatly The mixing time and vulcanization time of rubber materials are greatly reduced, and the production efficiency and overall mechanical properties of vulcanization bladders are improved.

Description

technical field

[0001] The invention relates to the technical field of auxiliary agents for vulcanization bladders, in particular to an adhesion promoter for vulcanization bladders and a preparation method thereof. Background technique

[0002] During the tire vulcanization process, the vulcanization bladder plays the role of inflating and expanding the shape, transmitting the pressure of superheated water, ensuring that the rubber material fills the mold cavity to achieve the required contour, and transmitting the heat required for tire vulcanization. Therefore, the vulcanizing bladder needs to have strong stress and strain tolerance and good thermal conductivity to meet the process requirements of repeated inflation and deflation cycles under high temperature and high pressure conditions.

[0003] In order to meet the above requirements, the vulcanizing bladder usually uses butyl rubber with high heat resistance and chemical degradation resistance as the main raw material,...
