Preparation and Characterization on an Environment Friendly Used Rubber Powder Modified Pulp Sediments Composites

摘要

A new composite material was prepared by using pulp sediment as matrix, and used rubber powder as toughening agent to recycle both wastes. The effect of used rubber powder content on the pulp sediment properties, the morphology and curing conditions of used rubber powder / pulp sediment composites were studied. The results show that the mechanical properties of used rubber powder / pulp sediment (8/100) are good. The fracture surface of used rubber powder/ pulp sediment (8/100) samples are well-distributed by scanning electronic microscopy (SEM) analysis. The best formulation is 100 phr pulp sediment and 8 phr used rubber powder, and the best curing conditions are at temperature 150 °C under 5 MPa for 15 minutes.
