Embodiment 1

[0041] A luminous PLA filament for 3D printing is prepared by parts by weight from 90 parts of PLA particles, 10 parts of silanized blue luminous powder, 1 part of stearic acid amide, and 1 part of oxidized polyethylene wax.

[0042] (1) Silanization treatment of luminous powder

[0043] Silane coupling agent, blue luminous powder (Sr 2 MgSi 2 o 7 :Eu) and absolute ethanol were weighed at a mass ratio of 1:20:100, then stirred and mixed with a magnetic stirrer at a speed of 100 rpm for 30 minutes, and the slurry was dried at 50°C for 20 hours after stirring to obtain silanized luminous powder. The dried luminous powder is ground and crushed, passed through a 200-mesh sieve, and vacuum-packed for later use;

[0044] (2) Raw material premixing

[0045]The PLA particles were dried in a 60°C electric blast drying oven for 24 hours to remove the moisture adsorbed therein. Weigh 90 parts of dried PLA particles, 10 parts of luminous powder after step (1), 1 part of stearic acid ...

Abstract

The invention belongs to the technical field of 3D (Three Dimensional) printing materials and discloses a luminous PLA (Polylactic Acid) wire rod for 3D (Three Dimensional) printing and a preparation method thereof. The preparation method comprises the following steps: (1) mixing and treating a silane coupling agent, blue luminous powder and absolute ethyl alcohol at the mass ratio of 1 : (20 to 30) : (90 to 110); drying to obtain silanized luminous powder; (2) mixing the following components in parts by weight: 80 to 90 parts of PLA, 10 to 20 parts of the silanized luminous powder, 1 to 2 parts of stearamide and 1 to 2 parts of oxidized polyethlene wax, so as to obtain a mixed material; (3) adding the mixed material into an extruder and extruding and granulating to obtain a pelletized material; (4) charging the pelletized material into a 3D printing wire rod extruder and extruding so as to obtain the wire rod. The wire rod disclosed by the invention has a smooth surface, has bending resistance and is suitable for tabletop FDM (Frequency-division Multiplexing) printers; the product has a good visual effect under light illumination and sends out bright blue light after sufficiently absorbing light; the product has great luminous intensity and long luminous time and can be used for absorbing the light / radiating the light infinitely.

Description

technical field [0001] The invention belongs to the technical field of 3D printing materials, and in particular relates to a luminescent PLA wire for 3D printing and a preparation method thereof.
