摘要
The present invention is to apply a reactive silicone oligomer solution represented by the following structural formula (I) having a functional group at the end of the molecular chain containing a reaction initiator on the surface of the vulcanizing bladder for tires, and if necessary, crosslinking with a reaction accelerator to coat The surface modification method of the vulcanization bladder for tires using the reactive silicone oligomer characterized by the above-mentioned.;Wherein X is -OH, -COOH, -SH, or -N 2 H group,;R is a -CH 2 -,-[-CH 2- ] 3 -group, n is an integer from 0 to 8.;By using the tire vulcanization bladder whose surface is modified in accordance with the method of the present invention, it is easy to pull out the finished tire by lubricating the modified silicone rubber on the surface of the vulcanizing bladder without applying the release agent inside the tire, and thus can be repeatedly used. The stirring device and the coating device required for GIP coating are unnecessary, and the work environment and the like can be improved, and the cost and time can be saved.
