preparation example Construction

[0025] like figure 1 Shown, a kind of preparation method for the luminous PLA wire rod of 3D printing comprises the steps:

[0026] Step 1. According to the percentage by weight, 50% to 80% of PLA plastics and 20% to 50% of phosphorescent PP plastic masterbatches are blended in proportion, and the blended raw materials are placed in a closed environment at 90°C for 7 to 9 hours. dry;

[0027] Step 2, the dried raw materials are placed in a double-shaft blade mixer and fully mixed;

[0028] Step 3, extruding the mixed raw materials through a single-screw extruder to obtain the luminescent PLA wire for 3D printing, wherein the extrusion temperature is set at 195-210°C, and the speed of the single-screw extruder is 20 ~40rpm.

Embodiment 1

[0029] Example 1, blending 80% PLA plastic and 20% phosphorescent PP plastic masterbatch, using the above-mentioned preparation method for luminescent PLA wire for 3D printing, to prepare the luminescent PLA wire for 3D printing.

Embodiment 2

[0030] Example 2, blending 70% PLA plastic and 30% phosphorescent PP plastic masterbatch, using the above-mentioned preparation method for 3D printing luminescent PLA filament, to prepare the luminescent PLA filament for 3D printing.

Abstract

The invention relates to a luminescent PLA wire used for 3D printing, and a preparation method thereof. The preparation method comprises the following steps: blending 50-80 wt% of PLA plastics with 20-50 wt% of phosphorescent PP plastic master batches, and drying above raw materials; fully the mixing the dried raw materials; and carrying out extrusion molding on the mixed raw materials to prepare the luminescent PLA wire used for 3D printing. A certain proportion of the phosphorescent PP plastic master batches is mixed with the PLA plastics, and the PP plastics in the phosphorescent PP plastic master batches are used to effectively fusion of phosphorescence powder and the PLA plastics, so the PLA wire has luminescence performance. The luminescent PLA wire has the advantages of simple raw materials, simple preparation method, and no inorganic-polymeric mixing incompatibility problem.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a luminescent PLA wire for 3D printing and a preparation method thereof. Background technique [0002] With the development of 3D printing technology, 3D printed products have developed from the original popular science products to functional products. PLA (polylactic acid) wire, as the main consumable for 3D printing, has good biodegradability and is a recognized environmental Friendly material; however, the traditional PLA wire cannot meet the needs of functional products, such as functional products that can emit light. Contents of the invention [0003] The object of the present invention is to provide a luminescent PLA wire for 3D printing and its preparation method, which can solve the above-mentioned problems existing in the prior art. [0004] The technical scheme that the present invention solves the problems of the technologies described above is as follows: [...
