Abstract

The invention provides a wood-plastic composite material with high bio-based content. The wood-plastic composite material comprises the following components in parts by weight: 30-90 parts of bio-based polyolefin resin; 2-10 parts of a compatilizer; 10-70 parts of plant fibers; 1-3 parts of a plant fiber surface modifier; 2-10 parts of a filling agent; and 0-2 parts of a processing aid. The plant fibers are subjected to alkalization treatment. The bio-based content of the wood-plastic composite material is greater than or equal to 80%, the wood-plastic composite material also has high toughness and high rigidity, the cantilever beam notch impact strength is greater than or equal to 5 KJ/m<2>, the bending modulus is greater than or equal to 3000 Mpa, and the wood-plastic composite material can be applied to children toys, tables, chairs and furniture.

Description

technical field [0001] The invention relates to the field of polymer materials, more specifically, to a wood-plastic composite material with high bio-based content and its preparation method and application. Background technique [0002] According to the source of raw materials, plastics can be divided into bio-based plastics and petrochemical-based plastics. How to fundamentally solve the crisis caused by plastic products to the environment and energy has become a hot topic. Bio-based plastics made from renewable biomass Provides a great solution for sustainable development. With the development of technology and biotechnology, the industrialization of bio-based plastic composite materials can be predicted to become a new economic hotspot and play an important role in the low-carbon economy. [0003] At present, there are many patents related to bio-based wood-plastic composite materials. The disclosed invention patents mainly use conventional polypropylene as the plastic ...
