Abstract

The invention discloses an ASA / PC 3D printing wire rod with low VOC release, which takes ASA / PC resin as a raw material, is added with modified porous calcium silicate, an accelerant, a heat stabilizer, an antioxidant and a lubricant, and has the advantages of good forming property and mechanical property, wide application field and high application value. Besides, the invention further disclosesa preparation method of the 3D printing wire rod, the prepared ASA / PC 3D printing wire rod is small in VOC release amount in the 3D printing forming process and good in smell in the forming process, and the greenization of the 3D printing forming process is effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an ASA / PC 3D printing wire with low VOC release and a preparation method thereof. Background technique [0002] 3D printing is a new manufacturing technology that integrates the disciplines of machinery, software and materials. It is based on the principle of material accumulation and forming, and is widely used in engineering, education, medical and other fields. As one of the mainstream technologies of 3D printing, fused deposition modeling has attracted people's attention due to its low cost, safe operation and simple post-processing. [0003] ASA resin is a ternary block copolymer composed of acrylonitrile, styrene and acrylate. The material not only has superior processability, mechanical properties and chemical corrosion resistance, but also has good weather resistance. PC resin has good mechanical properties, heat resistance and stability. It is an...
