Abstract

The invention provides an antistatic 3D printing material and a preparation method thereof. The preparation method comprises the following steps: weighing, by weight, 87%-94% of ABS, 5%-12% of an antistatic agent and 0.1%-1% of an antioxidant and carrying out uniform mixing under stirring to obtain a mixed material; and adding the mixed material into a double-screw extruder, and carrying out extrusion, pelletizing and drying treatment to obtain the antistatic 3D printing material. The 3D printing material prepared by the invention has good long-term antistatic performance, and can maintain good mechanical properties of ABS.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antistatic 3D printing material and a preparation method thereof. Background technique [0002] As a revolutionary processing method that changes traditional industries, 3D printing realizes the rapid prototyping of complex products and parts through additive manufacturing technology. In recent years, 3D printing technology has developed rapidly, and has maintained a rapid growth trend in the past few years. [0003] ABS is currently the most commonly used 3D printing consumables. Acrylonitrile-butadiene-styrene (ABS) is one of the five general-purpose plastics. It has excellent properties such as high impact resistance, high gloss, and good stability. It is widely used in automobiles. , electrical appliances, building materials and other fields, but the antistatic performance of ABS is not ideal.
