Abstract：As a critical structural component in wall-mounted air conditioner indoor units,the base traditionally utilizes high-impact polystyrene(HIPS)for its exceptional material properties.With advancements in material technology,novel plastic alternatives have emerged.A modified HIPS material is investigated,synthesized by blending recycled polystyrene(PS)waste from air conditioner casings with virgin HIPS through crushing,sorting,and melt extrusion processes,achieving significant improvements in resource circularity.To validate its performance,specimen testing evaluated strength fluctuations,while high-low temperature cycling tests assessed extreme environmental adaptability.Results indicate that the modified HIPS exhibits comparable or superior comprehensive properties to conventional materials,with minimal strength variations confirming stable performance.Post-cycling tests revealed no deformation or cracking,meeting stringent operational requirements.This innovation provides the home appliance industry with a high-performance material solution that synergizes resource efficiency and technical viability.
