Abstract

The invention discloses a high toughness composite for 3D (three dimensional) printing and a preparation method of the composite, and relates to the field of 3D printing materials. The composite comprises the following raw materials in parts by weight: 40-50 parts of polypropylene, 30-40 parts of polyethylene glycol terephthalate, 18-26 parts of lignin, 8-15 parts of polypropylene fiber, 5-9 partsof nano silica gel, 6-10 parts of fumed silica, 5-9 parts of a barite powder, 5-9 parts of silicon carbide, 4-8 parts of tung oil, 2-4 parts of 2-methylimidazole, 1.8-3.5 parts of a coupling agent and 3-7 parts of a plasticizer. Through a synergic matching effect of raw material ingredients, the composite is good in toughness, excellent in crack resistance, high in dimensional stability and material processability and wide in application scope, and the preparation method is simple.

Description

technical field [0001] The invention relates to the field of 3D printing materials, in particular to a high-toughness 3D printing composite material and a preparation method thereof. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others. [0003] A...
