Polyethylene (PE) pipe,as one of the main pipes used in municipal water supply and drainage engineering,has good corrosion resistance and wear resistance. However,in long-term use,PE pipes may have water leakage,aging and damage,etc.,and it is necessary to select high-quality PE materials and fill and modify them to improve the mechanical strength and durability of the pipes. In this regard,high density polyethylene (HDPE) was filled and modified by bamboo cuttings and papermaking white mud respectively,and the effects of the amount of bamboo cuttings added,the mixing ratio of bamboo cuttings and bamboo pulp fiber,and the amount of white mud added on the mechanical properties of HDPE composite were analyzed,and the feasibility of preparing HDPE composite material strengthened by bamboo and paper leftovers into water supply and drainage pipes for municipal engineering was evaluated. It provides reference for the optimization of mechanical properties of pipes.
