Method for manufacturing thermoplastic vulcanizates

Abstract

A method for manufacturing thermoplastic vulcanizates includes the steps of: subjecting rubber granules, thermoplastic pellets, a filler powder, a cross-linking auxiliary agent powder, a vulcanization accelerator powder, a vulcanizing agent powder, and an auxiliary agent powder to evenly mixing so as to obtain a first mixture; introducing the first mixture into an extruder; introducing, in whole or divided into two portions, a processing oil into the extruder to be evenly mixed with the first mixture so as to obtain a second mixture, the processing oil being present in an amount ranging from 130 parts by weight to 200 parts by weight based on 100 parts by weight of the rubber granules; and subjecting the second mixture to dynamic vulcanization in the extruder so as to obtain the thermoplastic vulcanizates.
