Surface modification method of vulcanized bladder for tire using reactive silicone oligomer

摘要

In the present invention, a reactive clicolorimomo solution represented by the following structural formula (I) having a functional group at the molecular chain terminal end containing a reaction initiator is applied on the surface of a vulcanizing bladder for a tire, and if necessary, crosslinked with a reaction promoter, The present invention also relates to a method for modifying the surface of a vulcanized bladder for a tire using the reactive silicone oligomer.;Wherein X is-OH,-COOH,-SH, or-N₂H group and R is-CH₂-,-[-CH₂-]₃-group, and n is an integer of 0 to 8.;By using the tire vulcanized bladder modified in accordance with the method of the present invention, the finished tire can be easily drawn out by the lubricating action of the modified silicone rubber on the surface of the vulcanized bladder even without a chart of the tire internal release agent, The stirring device and the charting device necessary for coating are unnecessary, and the work environment and the like can be improved, and the cost and time can be saved.
