Abstract
The invention discloses a kind of UV adhesive for 3D printing moldings formed therefrom and application thereof.The adhesive by following weight than material composition：Polyolefin UV oligomer：25~80%, polyalcohol acrylate monomer：10~50%, light trigger：1~10%, oxygen resist 1~15%.The adhesive is used for bullion manufacture and dental casts, can be completely vaporized after the adhesive photocuring at lower temperature (600 700 DEG C), not residual ash, more accurate smooth die cavity can be formed.The adhesive can be used for 3D projection printing of mercury lamp or the 405nm LED for light source, while can also meet continuous light high speed 3D printing.
Description
Technical field
The present invention relates to photocuring 3D printing field, more particularly to a kind of UV adhesive for 3D printing moldings formed therefrom and
Its application in bullion and dental casts.
Background technology
Current Jewelry Accessories and dental casts generally use are wax-loss casting process, and the technique process is complicated, time-consuming, takes
Manually；Technological process is that drawing-engraving-moulding mould-comes unglued mould-casting-kind of tree-lost-wax casting-postprocessing working procedures.
This adhesive is used for Jewelry Accessories and the technological process of dental casts is：Drawing -3D printing-kind of tree-lost-wax casting -
Postprocessing working procedures, substantial amounts of manpower and equipment cost can be saved, and the vaporized product of this adhesive is carbon dioxide, water,
It is harmless to the human body, it is environmentally safe, and also the die cavity precision and round and smooth degree that are formed are better than traditional lost wax process.
It can be seen that being used for bullion and dental casts using this adhesive has efficiently, the effect of clean manufacturing.
The content of the invention
The invention provides a kind of UV adhesive for 3D printing moldings formed therefrom, it can obtain and design using the adhesive
The physical model that drawing fits like a glove, the model can be directly used for vaporizing mold, the material and profile of design be obtained, in pearl
Substantial amounts of time and artificial, simplified four construction technologies can be saved in jewelry decorants or dental casts manufacture.
It is characterized in that：By following weight than material composition：Polyolefin UV oligomer：25~80%, polyalcohol propylene
Acid ester monomer：10~50%, light trigger 1~10%, oxygen resist 1~15%.
Wherein described polyolefin UV oligomer structure formulas are：
The polyalcohol acrylate monomer structure formula is：
The light trigger is 184 and 369 mixture.
The oxygen resist is allyloxy methacrylate, and its structural formula is：.
It can be used for the casting of Jewelry Accessories and dental repair provided by the present invention for the UV adhesive of 3D printing moldings formed therefrom
Make.
Seen from above, the technical scheme of example is applied using present invention side, due to matching somebody with somebody in this adhesive containing 25~80% weight
The polyolefin UV oligomer of ratio：10~50% weight proportion acrylic polyol monomers；1~10% initiator (184,369),
1~15% oxygen resist (allyloxy methacrylate).And polyolefin UV oligomer and polyalcohol acrylate monomer gather
Product after conjunction has good toughness, and has preferable vaporization effect, can completely vaporize when (at 600~700 DEG C) and not stay
Ash content, and vaporized product is carbon dioxide, water, nonhazardous gas produce.
In addition, 184,369 mixed initiator used in this adhesive, can effectively absorb the projection light source of 3D printer, make
Obtaining this adhesive can rapid printing shaping.
In addition, specially adding oxygen resist in this adhesive, oxygen resist causes this adhesive in the presence of having oxygen
Even if illumination also will not crosslinking curing, therefore the supper-fast 3D printing of continuous light can be realized.
To sum up, the method that mold is carried out using this adhesive, can quickly manufacture Jewelry Accessories and dental casts.Pass through experiment
Using proof, after the adhesive is molded by 3D printing, it can easily substitute traditional wax-loss casting process, the works of Shao Liao tetra-
Sequence, a large amount of human and material resources are saved, and reduce the environmental pollution of traditional lost wax process.
Embodiment：
The present invention is described in detail below in conjunction with specific embodiment, herein illustrative examples and explanation of the invention
For explaining the present invention, but it is not as a limitation of the invention.
Embodiment 1
The UV adhesive for 3D printing of the present embodiment, this adhesive contains thick liquid admittedly for 100%, in adhesive
Including at least following weight than material：Polyolefin UV oligomer：25~80%, polyalcohol acrylate monomer：10~50%,
Initiator：(184,369) 1~10%, oxygen resist (allyloxy methacrylate) 1~15%.Polyene in this adhesive
The polymerizate of hydrocarbon UV oligomer has excellent toughness and structural strength.In addition, initiator is specially added in this adhesive
(184,369), this composite initiator can cause adhesive rapid precisely solidification in the projection of 3D printing, obtain and design drawing
The same model.In the present embodiment, preferably it is by the molecular weight control of above-mentioned polyolefin UV oligomer：15000-17000
Experiment proves：Structural strength and tough performance when the molecular size range of polyolefin UV oligomer is above range reach
To a relatively perfect balance.Analysis of experimental data be shown to be molecular weight it is too small when (＜ 15000), high-temperature evaporation casting film can be caused
Mould intracavity wall is not smooth enough, and brittle cracking)：When molecular weight is too big (＞ 17000), UV molding rates can be had a strong impact on and mixed
Dissolubility), and molecular weight, in 15000-17000, the reaction rate just on 3D printer, structural strength and tough performance reach
Optimal balance.
Embodiment 2
The adhesive of the present embodiment with embodiment 1 except that, this adhesive also includes：Polyalcohol acrylate list
Body, its weight proportion are 10~50%.Polyol structure monomer has low-temperature vaporization, adds the adhesive solidification that the composition makes
Product afterwards is easier lost-wax casting.
Embodiment 3
The adhesive of the present embodiment with embodiment 2 except that, also include in this adhesive：Oxygen resist (allyloxy
Methacrylate), its weight proportion is 1~15%.Oxygen resist causes adhesive not crosslinked under aerobic environment instead
Should, add the composition and cause this adhesive except being printed using the intermittent light 3D printer that the LED of mercury lamp, 405nm is light source
Outside, moreover it is possible to meet the 3D printing pattern of continuous ultraviolet light.
The specific weight proportion of the adhesive of the present embodiment is as shown in the table：
| Formula | Weight proportion |
