There are many studies on the process and function of epp-based wood-plastic foam materials, and the explanation of the short foaming mechanism; the plant fibers used to enhance epp materials mainly include wood (coniferous wood, broad-leaved wood), wood flour and hemp fiber. However, the study of epp-based wood-plastic foaming composite materials using bamboo powder as the reinforcing phase is still very rare; the influence of plant fiber dosage and particle size on the foaming materials is only a simple test data expression, and there is no common standard and system. Most of the rules are concentrated on the study of mechanical functions, and less on the rheological function of composite data; the interface modification mechanism of composite data, the effect of coupling agents in the entire composite data system, and the coupling agent and development The study of the synergistic effect of foams cannot be deepened;

The use of various additives in the epp process has not yet reached the optimal cooperation; the influence of the cell shape and the mechanical functions such as the impact strength and tensile strength of the foamed product, water absorption, aging resistance, and dynamic mechanical functions have not yet been reached Common conclusions; there are few systematic discussions on the mechanical functions, interface shapes, rheological functions, etc. of bamboo-plastic foam composite materials; micro-foamed wood-plastic products with high fiber content, wide application fields, high inductive functions, and long service life Development is in urgent need of discussion.
