METHOD OF INTERFACE INDUCEMENT FOR PREPARATION OF PERMANENT ANTISTATIC POLYOLEFINE/ CACO_3 COMPOSITES

摘要

In this study, preparation of permanent antistatic polyolefine/composites by Interface Inducement Method is investigated. The inducement of CaCO_3 surface binds up low-molecular-weight antistatic agents on the interface between CaCO_3 and matrix resin, and prevents the loss in water -washing. Thus permanent antistatic polyolefine/CaCO_3 composites are achieved by addition of low-molecular-weight agents. The surface resistivity of PP resin added with antistatic agent B increases to 10~(16) Q after 2 times of water-washing. While PP/CaCO_3 composites added with antistatic agent B or B complex show excellent permanent antistatic properties with surface resisitivity remains unchangeable after water-washing.
