Effects of processing agents on the processing properties of wood powder/HDPE composites
摘要
Abstract
Wood powder/high density polyethylene(HDPE)composites were fabricated by twin screw extruder,and the effects of seven processing agents on the processing and mechanical properties of the wood powder/high density polyethylene were analyzed. Results showed that the dispersity of wood powder is dependent on the type of processing agent. The addition of octadecanoic acid(HSt)could improve the dispersity significantly. However,ethylene bis stearamide(EBS),zinc stearate(ZnSt) and calcium stearate(CaSt)are not helpful for improving the dispersity of wood powder. Meanwhile, adding of plasticizer could reduce energy consumption during the processing of the composites. The flexural and tensile strength of the wood powder/HDPE composites with PE-g-MAH was 31.6% and 87.2%,respectively,higher than those of HDPE without wood powder. In contrast,adding EBS、ZnSt、CaSt、HSt and low molecular PE in wood powder/ HDPE could reduce the mechanical property of the composites.The results are useful for the optimization of the processing technology and formula of wood plastic composites.关键词
