Abstract

The invention belongs to the field of high polymer materials, and particularly relates to an antibacterial antistatic 3D printing material and a preparation method thereof. The material comprises thefollowing components in percentage by mass: 88-94% of ABS, 5-9% of an antistatic agent, 1-3% of an antibacterial agent, 0.1-0.5% of a coupling agent and 0.1-1% of an antioxidant. Wherein the melt flowrate of the ABS ranges from 14 g / 10 min to 18 g / 10 min. Compared with the prior art, the antibacterial antistatic 3D printing material provided by the invention has good long-term antibacterial and antistatic properties, and maintains good mechanical properties of ABS.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an antibacterial and antistatic 3D printing material and a preparation method thereof. Background technique [0002] 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, especially for shells of home appliances, toys, kitchen supplies, stationery, etc. 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, and is more inclined to peo...
