Abstract

A Tetra package recovered PE / PLA wire used for 3D printing and a preparing method thereof are disclosed. The wire is prepared from, by weight, 50-94% of Tetra package recovered PE, 3-42% of PLA, 0.1-8% of a compatilizer, 0.01-2% of a fluorine-containing processing auxiliary agent, and 0.01-2% of white oil. The method includes (1) drying, (2) material weighing, (3) high-speed kneading, (4) melting and extrusion, (5) cooling and traction and (6) rolling and bundling. Low density polyethylene (simplified as the Tetra package recovered PE) which is prepared through separating waste paper plastic aluminum packages of beverage, milk, and the like and the polylactic acid (PLA) are blended to prepare the polymer wire suitable for 3D printing. Green cyclic reutilization of polymer materials is achieved, the application range of the Tetra package recovered PE is broadened, and the novel wire for 3D printing is provided.

Description

technical field [0001] The invention belongs to a Tetra Pak recycled PE / PLA wire used for 3D printing and a preparation method thereof. Background technique [0002] At present, PLA and ABS are the most commonly used polymer materials for fused deposition rapid prototyping (FDM). With the popularization of FDM 3D printing technology, researchers have developed more and more 3D printing filaments, such as PC, PA, PEEK, PVA, HIPS, PETG, PCL, filaments. The emergence of these filaments meets the needs of FDM 3D printing applications. different needs in the field. However, the raw materials used in these wires are directly derived from petrochemicals, which aggravates the consumption of oil resources that are increasingly depleted. [0003] In recent years, the consumption of paper-plastic-aluminum composite packaging (Tetra Pak) has gradually increased, and discarded paper-plastic-aluminum packaging accounts for an increasing proportion of urban solid waste. The annual usage...
