High performance tread rubber manufacturing method using silanization reaction of ionic liquid in situ catalytic filler

摘要

The present invention discloses a method for producing a high-performance tread rubber using a silanization reaction of an ionic liquid in situ catalytic filler. In this method, raw rubber, filler, silane, and ionic liquid are placed in an open mixer or a closed mixer in order to obtain a rubber mixture, and the rubber mixture is remilled at a high temperature and sulfided at room temperature in the rubber mixture after remilling. Put pho and an anti-aging agent, and proceed to sulfidation of the rubber mixture to obtain a vulcanized rubber. In the method of the present invention, by using the ionic liquid as a surface silanization catalyst for the filler, the dispersion of the light-colored filler such as silica and rubber-filler interfacial performance are effectively promoted, and the amount of silane used can be greatly reduced, and tread rubber It greatly improves the dynamic performance of the material, reduces the rolling resistance and dynamic heat generation, has a simple process, and does not require additional processing equipment and procedures, and the high toughness has important prospects during tire manufacturing.
