Abstract:
Wood-waste rubber-HDPE composites(WRPC)were made with different rubber content. Thermogravimetric analysis(TGA)method was applied to investigate the thermal decomposition kinetics of wood flour, HDPE, waste rubber, WPC, and WRPC. The corresponding apparent activation energy(AAE)values were calculated with the Flynn-Wall-Ozawa model. The results showed that WRPCs have two weight loss stages at 230-380 ℃ and 430-580 ℃ due to thermal decomposition of wood/rubber and HDPE, respectively. The AAE values for wood, waste rubber, HDPE were 179.2, 243.8, 246.8 kJ/mol, respectively, while 239.3 kJ/mol for WPC. Decreased AAE values were found for WRPCs, i.e., 200.3-208.4 kJ/mol. It's concluded that the three raw materials, i.e., wood, rubber, and HDPE, synergistically react in WRPC decomposition process, and rubber addition content has evident influence on the thermal decomposition behaviors of WRPC.
