Description
Technical field
The invention belongs to macromolecule 3D printing wire rod preparation field, more particularly to it is a kind of using polylactic acid reclaimed materials prepare
3D printing wire rod and preparation method.
Background technology
Polylactic acid PLA as a kind of degradable high molecular material, because its good processing performance, dimensional stability and
Color dyeability, which is widely used in, prepares 3D printing wire rod.But the shelf-life of current PLA printings wire rod is generally shorter, very
Generally 3~6 months of wire rod after empty package, exposure is placed as 1~2 month in air, is more than the PLA print wires of shelf-life
The pulling that material is fed driving force in print procedure by printer is easily broken off, and causes to print wire rod supply interruption and 3D printing
Stop.If such wire rod is scrapped with regard to this, secondary it cannot use, it will generate more waste, be unfavorable for resource and make full use of.
But PLA wire rods are a kind of materials of easy degradation, after being squeezed out by high temperature several times, there is more PLA material meeting
It degrades, mobile performance is unstable, and wire rod is caused to be difficult to pull into diametrically stable round wire rod, institute in squeezing out preparation process
The wire rod of preparation present it is apparent it is rough, to have protrusion or pitting defects, line footpath thickness be more than controlled range；Thus wire rod is beaten through 3D
It prints printout made of (fusion sediment method, FDM) and significantly interlayer dent occurs, even occur deforming in right angle, sharp corner
Situation has seriously affected the quality and beauty of 3D printing device.
Invention content
In order to overcome the shortcomings and deficiencies of the prior art described above, the primary purpose of the present invention is that providing a kind of using poly- breast
3D printing wire rod prepared by acid recovery material.
Another object of the present invention is to provide the preparation method of the above-mentioned 3D printing wire rod prepared using polylactic acid reclaimed materials.
The purpose of the present invention is realized by following proposal：
A kind of 3D printing wire rod prepared using polylactic acid reclaimed materials, is grouped as by the group of following mass parts：
The polylactic acid reclaimed materials be by temperature setting be 170~225 DEG C single screw rod or double screw extruder squeeze out
And storage is not up to more than the wire rod of 0~18 month shelf-life or away from the production time for 0~24 month diameter in dry conditions
It is required that the pellet that is cut into of wire rod or above-mentioned wire rod.
The chain extender is the low viscosity compound containing epoxy group, preferably neopentylglycol diglycidyl ether, hexamethylene
