AUTOMATIC RUBBER POWDER PLASTICIZING METHOD AND EQUIPMENT FOR AUTOMATIC RUBBER POWDER PLASTICIZING METHOD

摘要

An automatic rubber powder plasticizing method used in recovery and utilization of waste rubber, which involves pulverizing waste rubber to form 10-40 meshes of rubber powder, adding activator and softener at weight ratio of rubber powder/activating agent/softening agent of 1:0.3-0.4%:8-18%, mixing uniformly, heating at 180-320? and retaining for 8-15 minutes to desulfurize and plasticize, after cooling, obtaining plasticized rubber powder. An equipment for plasticizing is provided, which comprises sequentially communicated stirring device (1), feeding device (2), thermal reaction device (3) and cooling device (4).
