Technical Field

The invention relates to the technical field of 3D printing, in particular to ink or adhesive for an inkjet 3D printer of a 3DP technology realized by an inkjet printer and a preparation method thereof.

Background

The 3D printing ink is an adhesive, and the ink is used in an inkjet 3D printing apparatus. The 3D printing technology is now mainly laser sintering melting powder molding (SLM) and laser sintering molding (SLS), and the other major class is inkjet bonding powder molding (3 DP).

The 3DP technology uses a nozzle to spray ink (namely, an adhesive) on a tiled powdery material, the ink has adhesiveness, a thin layer of powdery material is paved after one layer of ink is sprayed by using a computer 3D slicing technology, the adhesive powder is overlapped layer by layer, and finally an object to be printed is formed. The nozzle used by the 3D printer adopting the high-precision 3DP technology at the present stage is mainly also a nozzle of a common plane ink-jet printer, a 3D printing nozzle in the professional field is not produced by a nozzle manufacturer, special ink suitable for the 3D printer is not produced, the main 3D printing ink on the market is furan resin and phenolic resin which are used by common foundries for household use, and the main 3D printing ink is mainly used for a sand mold 3D printer, the resin glue is not special 3D printing ink and can be prepared by using a large amount of chemical substances, so that the resin glue has certain toxicity, meanwhile, the smell is sharp, the chemical substances exist, a little precipitate exists, the fluency also has certain influence, the nozzle is frequently blocked, the printer nozzle and parts are corroded, and the use is influenced.

The invention relates to an ink or adhesive which is newly developed according to the characteristics of a 3D printer and is specially suitable for ink-jet 3D printing equipment.

Disclosure of Invention

The invention aims to provide the ink and the preparation method thereof, wherein the ink is reasonable in formula, simple in preparation method, green and environment-friendly, high in smoothness, high in bonding strength and wide in application.

The technical problem to be solved by the invention is realized by adopting the following technical scheme:

the ink or the adhesive for the ink-jet 3D printer is characterized by being prepared from the following raw materials, by weight, 40-80 parts of silicate, 10-15 parts of carbonate, 20-50 parts of deionized water, 0.5-1 part of pH value regulator, 1-3 parts of surfactant and 1-3 parts of reinforcing agent.

The raw materials preferably comprise 45 parts of silicate, 15 parts of carbonate, 36 parts of deionized water, 2 parts of surfactant, 1 part of pH value regulator and 1 part of reinforcing agent.

Because the types and brands of the spray heads on the market are more, the components are adjusted according to the index requirements of the spray heads.

Another object of the present invention is to provide a method for preparing the special ink for 3D printing according to the present invention, which is characterized by comprising the following steps:

adding the silicate and deionized water into a reaction kettle, heating to 80 ℃, stirring and reacting for 3-6 hours;

adding carbonate at the reaction temperature of 80 ℃, reacting for three hours, cooling to 40 ℃, adding a pH value regulator, stirring, reacting for one hour, discharging, adding a surfactant before discharging, and stirring and mixing uniformly to form the main material. The main material was allowed to stand for several hours.

Filtering the main material for 2-15 times on a dust-free workshop filtering production line, and filling to obtain the product.

While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable to various fields of endeavor for which the invention may be embodied with additional modifications as would be readily apparent to those skilled in the art, and the invention is therefore not limited to the details given herein and to the embodiments shown and described without departing from the generic concept as defined by the claims and their equivalents.
