Abstract

The invention provides a carbon fiber enhanced polylactic acid 3D printing material and a preparation method thereof. The material is prepared from the following raw materials in parts by weight: 60 to 80 parts of polylactic acid, 5 to 15 parts of toughening agent, 2 to 10 parts of compatibilizing agent, 5 to 25 parts of modified carbon fibers, 0.1 to 2 parts of antioxidant, 0.5 to 2 parts of anti-hydrolysis agent, 0.05 to 1 part of crystallizing nucleating agent, 0.5 to 3 parts of mobile regulating agent and 0.2 to 2 parts of melt fusion enhancing agent. By adopting a surface modification technology of carbon fibers, the interface compounding performance with polylactic acid is improved; aiming at FDM (frequency division multiplex) 3D printing characteristics, the mobile regulating agent and the melt fusion enhancing agent are added so that the specific value between the strength of a printing material and the strength of a parent material is effectively improved; aiming at a phenomenon that the printing material is not dried before utilization, the anti-hydrolysis agent is used for inhibiting a problem that polylactic acid is easy to hydrolyze in a printing process; the whole performance of the material is improved through the coordination of the components in the formula.

Description

(1) Technical field [0001] The invention belongs to the technical field of 3D printing materials, in particular to a high-performance carbon fiber-reinforced polylactic acid 3D printing material applied to Fused Deposition Modeling (FDM) and a preparation method thereof. (2) Background technology [0002] 3D printing technology, also known as additive manufacturing technology, is a kind of rapid prototyping technology. The technique of constructing objects in a way. Common 3D printing technologies include fused deposition modeling (FDM), solidification forming (SLA), laminated solid manufacturing (LOM) and selective laser sintering (SLS). The most commonly used 3D printers are devices using FDM technology. [0003] At present, the materials used in FDM printers on the market mainly include ABS, PLA, etc. Compared with PLA, ABS materials will produce unpleasant smells and affect the environment when printing, ABS will produce warping deformation when printing large part mod...
