摘要

The ever-increasing amount of waste rubber product, especially waste tire rubber (WTR), has resulted in a serious environmental problem. One potentially attractive solution is to use the ultrafinely pulverized waste rubber as fillers for making high performance WTR based composites at lower cost. A pan-mill type equipment has been designed by our Lab. for pulverizing and bring about stress reactions of polymer, It can exert a strong squeezing force in normal direction and a shearing force in both radial and tangential direction like a three dimensional scissors. Polypropylene/WTR composite has been prepared through pan-milling in our Lab. After pan-milling at room temperature the size of WTR powders gets down to several micrometers from tens of millimeter (Fig. 1), the BET specific surface area reached 7.23 m~2 · g~(-1) from 0.007 3 m~2 · g~(-1) after 25 cycles of milling. Co-milling of WTR chips with polypropylene improves the dispersability of WTR powders (Fig. 2). The pulverizing process showed that fragmentation and size reduction predominates at initial milling stage, mixing of PP and WTR powders predominates at further pan-milling then forms composite powders with intimate mixing state and leads an abrupt reduction of total surface area due to mech-ano-implantation and mechano-difrusion.
