Abstract

The invention discloses a high-toughness TPU-based 3D printing material and a preparation method and application thereof. The high-toughness TPU-based 3D printing material is prepared from, by weight,115-205 parts of TPU, 15-26 parts of bis(pinacolato)diboron, 12-17 parts of zinc hyaluronate, 12-16 parts of chitosan, 6-14 parts of tetrachlorophthalic acid, 4-9 parts of manganese oxide, and 3-8 parts of rectorite powder. The high-toughness TPU-based 3D printing material is high in tensile strength, bending strength and impact strength and great in flame retardation effect, can be well appliedto the field of buildings and has certain economic values and social values.

Description

Technical field [0001] The invention relates to a 3D printing material, in particular to a high-toughness TPU-based 3D printing material, and a preparation method and application thereof. Background technique [0002] 3D printing technology is also called three-dimensional printing technology. It does not require machining or any molds to directly generate parts of any shape from computer graphics data, thereby greatly shortening the product development cycle, improving productivity and reducing production costs. Commonly used materials for 3D printing include nylon glass fiber, durable nylon materials, gypsum materials, aluminum materials, titanium alloys, stainless steel, silver-plated, gold-plated, and rubber materials. In the early stage of development, 3D printing technology could only be used for rapid prototyping due to its inadequate material technology. This new technology was once famous for its "rapid prototyping" technology. With the development of material technolog...
