Description

A kind of 3D printer wire rod
Technical field
The invention belongs to increase material manufacturing technology field, be specifically related to a kind of 3D printer wire rod.
Background technology
Circuit board is component indispensable in current information industry.At present, leading of the circuit board used in information industry Electricity circuit is by etching on copper-clad base plate or the method for Screen-printed conductive slurry (most argentiferous, copper) on substrate mostly Obtain.Use etching on copper-clad base plate to obtain circuit board, have the disadvantage that circuit board preparation technology long flow path, relatively costly, Environment is had potential pollution, conducting channel pattern adjustment difficulty thickness adjustability big, conducting channel poor by copper-containing etching waste solution. Use Screen-printed conductive slurry obtain circuit board, have the disadvantage that whole circuit-board processes long flow path and loaded down with trivial details, conduction in The costs such as conventional silver, copper are high, due to mesh limit cause circuit size low precision, easily occur that silk screen hole plug causes printing The defect etc. of circuit breaker.
For research and development of products and the individual character manufacturing of micro-batch, traditional copper-clad base plate etches or silk screen printing on substrate Electrocondution slurry method cannot adapt to such Production requirement.
Current 3D printer substantially can not adapt to two kinds of wire rods of different nature simultaneously, such as, can not use heat simultaneously Melted plastic wire and the metal wire rod of lf, both materials can not print simultaneously and combine.Therefore Current 3D printer cannot print plain conductor on plastic base.
Summary of the invention

Preferred version is:
PLA 50
Graphene 43
Nanometer silver 7.
The preparation method of this 3D printer wire rod, comprises the following steps:
(1) getting the raw materials ready, the formula recorded according to claim 1 or 2 weighs described PLA, Graphene, nanometer silver and auxiliary agent respectively；
(2) preparing mixture, the raw material weighed in step (1) is put into mixing 5-20min in high-speed mixer, mixing is all Even, obtain mixture；
(3) pelletize, the described mixture obtained in step (2) is added in double screw extruder, coupled extrusion, obtain deep Lycoperdon polymorphum Vitt is to the plastic pellet of black；
(4) prepare 3D and print wire rod, the plastic pellet obtained in step (3) is added twine machine, prepare 3D and print wire rod.
Further, in step (3), the process conditions of described double screw extruder are: extrusion temperature is 200-230 DEG C, The draw ratio of double screw extruder is 40:1～52:1, and the rotating speed of double screw extruder is 300-550rpm.
Further, in step (4), it is circular that described 3D prints the cross section of wire rod, a diameter of 1.7-1.8mm.
Further, in step (4), it is circular that described 3D prints the cross section of wire rod, a diameter of 2.8-3.0mm.
Compared with prior art, inventive formulation is simple, and the 3D of preparation prints wire rod and has high conductivity, and can be by general The 3D printer of logical plastic raw materials uses, and prints product as circuit board and comes.
