DEODORIZING METHOD FOR RECYCLING RUBBER WASTE

摘要

PURPOSE: A deodorizing method for recycling rubber waste is provided to solve odor problems generated in recycling waste rubber with mechanical properties, and to lower environmental loads. CONSTITUTION: A deodorizing method for recycling rubber waste comprises a step of mixing and stirring waste rubber powder and aroma oil aqueous solution in a mixer with a degassing apparatus during a process for desulfurizing rubber waste or preparing recycled rubber waste from waste rubber. The temperature of the mixing and stirring step is 120~200 °C, shearing velocity is 40~120 rpm. The mixing and stirring apparatus is a twin screw extruder equipped with 2~6 degassing apparatuses.
