Modified ABS material doped by boron nitride and carbon fiber nanoflakes and used for 3D printing, and preparation method thereof

Abstract

The invention provides a modified ABS material for boron nitride-doped and carbon fiber nanosheet 3D printing and a preparation method thereof. The preparation method is to mix the dried SBS and ABS with a surfactant; then add glass fiber and Boron nitride and carbon fiber nanosheets are mixed, heated, extruded through a screw, and dried to obtain a modified ABS material. The modified ABS material for 3D printing prepared by the present invention is less prone to warping and cracking, and its shrinkage performance when cold is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a modified ABS material for 3D printing of boron nitride-doped and carbon fiber nanosheets and a preparation method thereof. Background technique [0002] 3D printing (3DP) 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. [0003] 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 inf...

Problems solved by technology

[0005] Among them, ABS resin is the earliest material used in fused deposition modeling (FDM) technology. The printing temperature of this material is 210-260°C, and the glass transition temperature is 105°C. It has many advantages, such as high strength and good toughness. , impact resistance, insulation, corrosion resistance, and low temperature resistance. However, ABS needs to be heated when printing. At the same time, the material shrinks significantly when it is cold, and it is prone to quality problems such as warping and cracking.
