ADHESION METHOD OF SILICON RUBBER AND VULCANIZED BLADDER WITH IMPROVED ADHESIVE FORCE

摘要

PURPOSE: An adhesion method processes surface of a bladder rubber with compound to improve adhesive force as multiple functional groups on the bladder reinforces adhesive force with elements in silicon rubber. CONSTITUTION: A first step is to apply reactive liquid containing phenol resin to surface of a usual bladder rubber improve adhesive force with a silicon rubber. A second step is to post-vulcanize the bladder with the liquid applied in an oven in 100- 200°C for more than 30 minutes. A third step is to apply additional type liquid silicon rubber to the bladder with the liquid applied. A fourth step is to post-vulcanize the blader in the oven in 100-200°C for more than 30 minutes. The reactive liquid comprises alkyl phenol resin, isobutylene-isoprene copolymer, zinc oxide which is vulcanization activator and solvent to make it easy to apply.
