Abstract

The invention provides a zymolytic lignin-wood fiber-polyolefin hybrid composite material and a preparation method thereof, relating to a composite material and a preparation method thereof. The invention solves the problems of poor toughness and low-efficiency utilization of zymolytic lignin of a traditional wood-plastic composite material. The composite material provided by the invention is prepared from thermoplastic plastics, zymolytic lignin, a wood fiber material, filling and a processing aid. The preparation method comprises the following steps of: mixing, extruding and forming the thermoplastic plastics, the zymolytic lignin, the wood fiber material, the filling and the processing aid to obtain the zymolytic lignin-wood fiber-polyolefin hybrid composite material. According to the invention, the composite material can convert waste resources into biomass raw materials in the processing process, greatly decreases the production cost and solves the problem of great product brittleness of a traditional wood-plastic composite material technology.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof. Background technique [0002] Due to the global oil and other fossil resource crisis, the industry of producing fuel ethanol from renewable plant resources has developed rapidly. However, while using cellulose and hemicellulose to prepare fuel ethanol, a large amount of lignin residues are produced. Through the deep processing of forestry and agricultural biomass, a new type of recyclable and biocompatible material (biomass material) is gradually becoming an important new material for building a low-carbon economy, such as agricultural residues and forest products. Processing by-products all have the potential to become feedstock for low-cost biomass materials. [0003] As a main natural polymer in biomass, lignin is an available polyhydroxy thermoplastic polymer, and its structure depends on the type of biomass itself and the processing conditions. Lignin is largely der...
