Ink for acrylic acid 3D printingTechnical Field
The invention relates to the technical field of 3D printing, in particular to ink for 3D printing of acrylic acid for 3D printing of ink jet 3D printing of a 3DP technology.
Background
The 3D printing ink is a glue, which is used in inkjet 3D printing devices. The main category of 3D printing technology is now laser sintering melting powder molding (SLM) and laser sintering molding (SLS), and the other category is inkjet bonding powder molding (3 DP).
The 3DP technology is that a computer three-dimensional slicing technology is utilized, an object to be printed is converted into data of a slice, ink (namely, an adhesive) is sprayed on a tiled powdery material through a nozzle, then a layer of powder is paved, the adhesive powder is overlaid layer by layer, and finally an object to be printed is formed. The shower nozzle that the used shower nozzle of present stage high accuracy 3DP3D printer is mainly still ordinary plane inkjet printer's shower nozzle, the ink that mainly prints on the market is furan resin, phenolic resin, not specially print the ink of research and development for 3D, mainly used sand mould 3D printer, resin glue can use a large amount of chemical substances to prepare, consequently, certain toxicity has, the smell is also comparatively sharp simultaneously, also be the existence of chemical substance, there is the existence of some precipitates, the smoothness also has certain influence, often block up the shower nozzle, influence the use. The invention discloses acrylic acid 3D printing ink. The printing ink has the advantages of good fluency, no corrosion and nozzle blockage, strong adhesive force, three curing modes of curing agent curing, thermocuring, photocuring and the like, wide applicability and capability of printing various materials such as sand molds, ceramic powder, gypsum powder, various metal powder, high-temperature-resistant hard alloy powder, nylon powder and the like.
Disclosure of Invention
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
the ink for acrylic acid 3D printing is characterized by being prepared from the following raw materials, by weight, 50-70 parts of acrylic resin, 1-3 parts of peroxide, 25-50 parts of butyl ether alcohol, 1-3 parts of surfactant and 0.5-3 parts of silicon-based reinforcing agent.
The raw materials preferably comprise 65 parts of acrylic resin, 3 parts of peroxide, 2 parts of surfactant, 1 part of silicon-based reinforcing agent and 29 parts of butyl ether alcohol.
It is another object of the present invention to provide a method for manufacturing the ink of the present invention, characterized by comprising the steps of:
adding the acrylic resin and the peroxide into the butyl ether alcohol, adding the butyl ether alcohol into the reaction kettle, uniformly stirring, heating to 90 ℃, and reacting for 30 minutes; and cooling to 40 ℃, adding the silicon-based reinforcing agent, adding the surfactant, and stirring for 30 minutes 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.
