ABS matrix blends were prepared by melt blending method which filled with yakeli artificial stone waste power.Thermal decomposition process of ABS and ABS/yakeli artificial stone waste power composite were investigated by dynamic thermogravimetric analysis(TGA)at different heating rates.Kissinger and Flynn-Wall-Ozawa equations were used to calculate the thermal degradation activation energies.The results demonstrated that yakeli artificial stone waste had the effect of thermal decomposition process,increased the thermal stability of composite.The TG and DTG curves tended to high temperature zones with the increasing of heating rate,maximum thermal decomposition rate temperature increased gradually.The apparent activation energy of ABS/yakeli artificial stone waste power composite were higher than that of pure ABS by Kissinger and Flynn-Wall-Ozawa method,and apparent activation energies increased gradually with the increasing of yakeli artificial stone waste power.When contents of yakeli artificial stone waste power was 25%,the apparent activation energies of composite were 27.77%and 31.19%respectively higher than that of pure polypropylene.
