木粉、废旧橡胶和高密度聚乙烯复合材料的热解动力学特性
Thermal decomposition kinetics of wood/rubber/HDPE composites
摘要
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 rub⁃ber, 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, syner⁃gistically react in WRPC decomposition process, and rubber addition content has evident influence on the thermal de⁃composition behaviors of WRPC.关键词
