High-performance wood-plastic material for 3D printing forming and preparation method of wood-plastic material

Abstract

The invention belongs to the technical field of wood-plastic composites and preparation methods of the wood-plastic composites, and particularly relates to a high-performance wood-plastic material for 3D printing forming and a preparation method of the wood-plastic material. A high-performance wood-plastic wire rod for 3D printing and a preparation method of the wood-plastic wire rod aim to solve the problems of poor size stability and low mechanical strength of the existing wood-plastic material for the 3D printing. The wood-plastic wire rod for the 3D printing forming comprises a modified plant material, engineering plastic or a plastic alloy, a coupling agent or an interfacial compatibilizer, a lubricant, a heat stabilizer and a mineral packing, wherein the modified plant material is a plant material after modification. The preparation method of the wood-plastic wire rod comprises the steps that the plant material is subjected to modification treatment and mixed with other raw materials (or a modifier, the plant material and extruded raw materials are directly mixed); melt blending is performed; a blend compound is added to an extruder; extrusion and wire drawing are performed to obtain the wood-plastic wire rod for the 3D printing.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic composite materials and preparation methods thereof, and in particular relates to the field of wood-plastic materials for 3D printing molding and preparation methods thereof. Background technique [0002] 3D printing, also known as rapid prototyping technology, is also called additive manufacturing technology. It does not require traditional tools, fixtures and machine tools, but is based on digital model files, using adhesive materials such as metal powder or plastic Layer printing technology to manufacture objects of any shape. 3D printing technology is the integration of multidisciplinary technologies such as mechanical engineering, computer technology, numerical control technology, and material science. The most difficult and core technology of 3D printing is the development of printing materials. Therefore, the development of more diverse and multifunctional 3D printing materials has b...
