Abstract

The invention discloses a reclaimed polypropylene (PP)-based wood-plastic composite material and a preparation method thereof. The wood-plastic composite material comprises the raw materials by weight: 50 to 70 parts of reclaimed PP, 30 to 50 parts of natural plant fiber, 0.1 to 0.3 part of initiator, 0.1 to 6 parts of glycidyl methacrylate and 0.1 to 3 parts of styrene, wherein the sum of the weight parts of the reclaimed PP and the natural plant fiber is 100. By double monomer melt grafting in-situ reactive compatibilization, the compatibility of the reclaimed PP and the natural plant fiber is effectively improved, the interface bounding force between two phases is enhanced and the comprehensive performance of the material is improved. Various sectional materials can be extruded by different dies, so that industrialized production of the materials such as automobile internal lining panels, windows, doors and the like is realized.

Description

technical field [0001] The invention belongs to the field of wood-plastic composite materials, in particular to a recycled PP-based wood-plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic composite (WPC) is a new type of environmentally friendly composite material made by using wood powder, bamboo powder, crop straw powder, fruit shell powder and other natural plant fibers and plastic resin or waste plastic as the main raw materials, mixed at high temperature, and formed. composite material. Increasing the application of this material can improve the comprehensive utilization level of natural plant fibers, reduce white pollution, and reduce waste caused by improper disposal of waste resources. Therefore, more and more people pay attention to it. [0003] When the hydrophilic natural plant fiber and the lipophilic plastic matrix are combined, the interface interaction strength is small, the dispersion of the natural plant...
