摘要
以废旧聚乙烯、木粉和粉煤灰为主要原料,添加一定量的加工助剂,经高温模压成型制备了一种新型塑木复合材料,并采用辐射交联技术对复合材料进行改性;研究了木粉、粉煤灰和辐射剂量对复合材料物理机械性能的影响。结果表明:该复合材料经60 kGy辐射后,其弯曲强度、拉伸强度和冲击强度分别提高了11.2%、37.5%和12.1%,材料的摩擦系数也降低了12.6%。
In this paper,a novel wood-plastic composites（WPC）was prepared by the compression molding process using waste polyethylene（PE）,wood flour,fly ash as main material and by adding the processing addtive,the WPC was modified with gamma radiation.It investigated the effects of wood powder content,fly ash content and dosage of radiation on the mechanical properties of wood-plastics composite,The result showed that,using the dose of 60 kGy could improve the flexural,tensile,and impact strength of WPC by 11.2%,37.5% and 12.1% respectively,and the friction coefficient was decreased by 12.6% after γ-ray irradiation.
