Description
Technical field
The present invention relates to the technical field of full-color 3D printer consumptive material, more particularly, is related to a kind of suitable for full-color
Colourless adhesive glue of 3D printer and preparation method thereof.
Background technology
Full-color 3D printer is the important technology of 3D increasing material manufacturings, and it is that it is logical with the maximum difference of other 3D printers
Color true to nature can be shown on base material by crossing the figure of three-dimensional data output.At present, what is be most widely used in the world is complete
Color 3D printer has Printer150,250,350,450,510,650,850 types and Projet160,260,360,460,
660,860 types, these printing types can realize the combinations of 6,000,000 kinds of colors, and real colour is gorgeous；Such series printer
Colourless adhesive and composite powder are mainly used as printed material, while uses CMYK colour technologies.These equipment generally uses
Be Hewlett-Packard of the U.S. production heat foamable shower nozzle, but external printer technology be all hardware business monopolize material supply, to China
3D printer application adds very big cost.
Both at home and abroad there are some shortcomings in the colourless adhesive glue of full-color 3D printer at present, such as：Ground powder be applicable it is poor,
The precision of printing shaping is low, color edges control is fuzzy, color shows poor power, base material powder-stuck overlong time, bond after hold
Easy efflorescence, color weatherability difference etc. problem, it is impossible to meet the actual operation requirements of full-color 3D printer, limit full-color 3D
The expansion application of printer, and the colourless adhesive glue of existing full-color 3D printer is only applicable to load heat foamable shower nozzle
Full-color 3D printer, often there is burning head suitable for the adhesive glue of piezo jets, the scope of application is small.
The content of the invention
For deficiencies of the prior art, it is an object of the invention to provide a kind of suitable for full-color 3D printer
Colourless adhesive glue and preparation method thereof, to solve ground existing for the colourless adhesive glue of existing full-color 3D printer
Powder be applicable the control of poor, color edges is fuzzy, color shows poor power, base material powder-stuck overlong time, bond after easy efflorescence,
Color weatherability is poor, burns the problem of shower nozzle etc..
Above-mentioned purpose is realized, the present invention adopts the following technical scheme that：
A kind of colourless adhesive glue suitable for full-color 3D printer, it is characterised in that its constituent is by weight ratio:
10 ~ 35 parts of organic cosolvents；0.1 ~ 0.5 part of polymer binder；0.2 ~ 5 part of cationic binder；0.1 ~ 1 part of resistance penetration enhancer；0.1
~ 0.3 part of sterilization antiseptic；0.1 ~ 1 part of pH adjusting agent；0.1 ~ 2 part of curing agent；0.1 ~ 1.2 part of surfactant；0. 1~
0. 5 parts carry toner；64 ~ 87 parts of ultra-pure waters.
The preparation method of a kind of colourless adhesive glue suitable for full-color 3D printer, it is characterised in that including as follows
Step：
（1）Above-mentioned ultra-pure water is previously added in the vacuum reaction kettle that vacuum is -0.090 kpa, is turned in 200 ~ 300 r/min
The lower stirring at low speed of speed, then sequentially adds the organic cosolvent, polymer binder, cationic binder, resistance penetration enhancer, sterilization
Preservative, pH adjusting agent, curing agent, surfactant, carry toner, be sufficiently mixed and stir 2 ~ 4 h, temperature control 55 DEG C ~
65℃。
（2）Mixed liquor after stirring is cooled to room temperature, is aged 22 ~ 26 hours, that is, obtains the colourless viscous of full-color 3D printer
Mixture glue.
Compared with prior art, the present invention has the advantages that：
1st, the present invention adds polymer binder, cationic binder, resistance penetration enhancer when preparing colourless adhesive glue, and leads to
Cross research find when oozed using 0.1 ~ 0.5 part of polymer binder, 0.2 ~ 5 part of cationic binder, 0.1 ~ 1 part of resistance, 0.1 ~ 1.2
Part surfactant, 0. 1 ~ 0. 5 parts when carrying toner agent composite usage, colourless adhesive glue of the invention is solving ground powder
End be applicable poor, printing shaping precision is low, color edges control obscure, color shows poor power, base material powder-stuck overlong time,
Easy efflorescence after bonding, color weatherability are poor, shower nozzle easily burns and A levels are all shown in a problem, so as to overcome existing colourless bonding
The problem of agent glue is present.
2nd, in order that obtaining colourless adhesive glue in the case where meeting the actual demand of existing 3D printer, and can enough possesses excellent
Quality, the present invention sterilization antiseptic, pH adjusting agent and curing agent are added in preparation process, sterilization antiseptic can prevent
Glue is during long-term use because of ingress of air so as to which breed bacteria influences the quality of glue；And pH adjusting agent can cause glue
Aqueous systems are in weak basic condition（pH=7~10）Under, such glue is more stable in storage, and this is mainly due in acyclic acidic
Polymer substance under border in glue easily hydrolyzes, and the moisture content in the easy absorption air of alkalescence too strong glue so that glue
The viscosity decline of water；The addition of curing agent, curing rate and intensity can be accelerated, be advantageous to the lifting of product quality.
3rd, colourless adhesive glue prepared by the present invention disclosure satisfy that the actual operation requirements of full-color 3D printer, expand
The application market of full-color 3D printer, is advantageous to industrialized production.
4th, the colourless adhesive glue for the full-color 3D printer that the present invention prepares can be widely applied to load piezoelectric type
The full-color 3D printer of shower nozzle, it can apply to load the full-color 3D printer of heat foamable shower nozzle again, it is applied widely.

The colourless adhesive glue for the full-color 3D printer prepared it can be seen from above-mentioned Tables 1 and 2 using the method for the present invention
Water solve ground powder be applicable poor, printing shaping precision is low, color edges control obscure, color shows that power is poor, base material powder
Easily efflorescence, color weatherability be poor after end bonding overlong time, bonding, shower nozzle easily burns and A levels are all shown in a problem, this explanation
The colourless adhesive glue prepared using the present invention disclosure satisfy that the actual operation requirements of full-color 3D printer, expand full-color 3D
The application market of printer.
The above-mentioned implementation of the present invention is only example to illustrate the invention, and is not the embodiment party to the present invention
The restriction of formula.For those of ordinary skill in the field, it is different that other can also be made on the basis of the above description
The change and variation of form.It is every belong to obvious changes or variations that technical scheme amplifies out still in
The row of protection scope of the present invention.
