Use of resource-rich wastepaper/recycled plastics as raw materials in the production of wood-plastic composites(WPC) can alleviate the shortage of wood resources, reduce pollution and has a attractive prospect. In this paper, old newspaper fiber(ONPF)/recycled-polypropylene(rPP) Wood-Plastics Composite(WPC) was prepared by means of mixing processing and compression molding. The effects of technical conditions on the mechanical properties of WPC were investigated. The structure of composite was characterized by means of FTIR and SEM. The results show that, Wastepaper and waste-PP can be used as raw materials for preparation of WPC. The suitable preparation process for wastepaper/rPP composites was: wastepaper fiber 20%, blending temperature 175°C, blending time 15min, molding pressure 12MPa, molding temperature 175°C and molding time 10min. In these conditions, tensile strength and flexural strength of wastepaper/rPP composites are 23.6MPa and 28.8MPa respectively, increased by 20.9% and 12.6% compared to those of rPP matrix. The elongation at break of WPC is 10.6%, and the flexural modulus is 1328.9MPa，increased by 7.7% compared to those of rPP matrix. The structure analysis found that there is no chemical reaction between the fibers and the matrix. The research results have important practical significance in the field of printing and packaging waste recycling and utilization, environmental protection and energy saving.
