Abstract

The invention relates to a 3D printing wood-plastic composite material and a preparation method thereof. The 3D printing material is composed of the following components in parts by weight: 100-150 parts of natural plant fiber, 125-175 parts of polyolefin plastic, 20-30 parts of mineral filler, 1-5 parts of coupling agent, 10-15 parts of dispersant, 5-10 parts of lubricant and 15-20 parts of toughener. The preparation method comprises the following steps: pulverizing the plant fibers, drying, modifying with the processing assistants, blending with the polyolefin granules, extruding the mixture with a double screw granulator to obtain a master batch, mixing the master batch and polyolefin in a certain mass ratio, extruding with a double screw extruder, carrying out wire drawing, and reeling. The 3D printing material has the appearance of the wood product and the processing characteristics of the wood-plastic material, has wide application range, and provides a more diversified environment-friendly material for 3D printing.

Description

technical field [0001] The invention belongs to the technical field of 3D printing material manufacturing, and relates to a wood-plastic composite 3D printing material prepared from plant fibers and polyolefin plastics and a preparation method 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 printers can manufacture many items, such as airplanes, pistols, food, human organs, children's toys, etc. 3D printing technology is a major breakthrough in the world's manufacturing technology field in the past 20 years. It is the integration of multidisciplinary technologies such as mechanical engineering, computer technology, numerical control technology, and mater...
