A method of surface-modifying for waste-rubber using corona discharge

摘要

PURPOSE: Provided is a method for modifying the surface of waste rubber by using a corona discharging treatment, by which the surface of the waste rubber is activated and the waste rubber has an excellent mixing-ability with other material, therefore, the recycled rubber is obtained by mixing the waste rubber with pure rubber. CONSTITUTION: The surface of the waste rubber is modified by moving the waste rubber powder at a uniform velocity of 10-15cm/sec and simultaneously performing the corona discharging treatment with an output of 10-12KV for 300-400 seconds. And the recycled rubber is produced by mixing 100pts.wt. of the pure rubber with 10phr pts.wt. of the surface-modified waste rubber powder having a particle size of 10-400 micrometer.
