The UV light-cured water-based resin comprises the following raw materials in parts by weight: 1-10 parts of polypropylene oxide ether glycol, 1-10 parts of polypropylene oxide glycol, 5-10 parts of isophorone diisocyanate, 0.5-2 parts of dibutyltin dilaurate, 2-5 parts of dimethylolpropionic acid, , 2 to 5 parts of hydroxyethyl acrylate, 0.01 to 0.2 part of p-methoxyphenol, 2 to 5 parts of 2, 2-dimethyltrimethylene cyclic carbonate, 2 to 7 parts of nano magnesium hydroxide, 1 to 10 parts of a photoinitiator, 10 to 30 parts of glycerol dimethacrylate and 10 to 30 parts of hexanediol diacrylate.The finished product provided by the invention has excellent hydrophilicity and mechanical properties, and is short in curing time, good in solvent resistance, green, environment-friendly and easy toclean.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a UV photocurable water-based resin. Background technique [0002] With the popularization of 3D printing technology, DLP / SLA 3D printing technology is being used more and more. 3D printing is also called "rapid prototyping technology". It realizes the manufacture of three-dimensional objects by laying up printing materials layer by layer. . [0003] After 3D printing, UV light curing is required, and the excess resin after 3D printing needs to be removed. At present, most of them use solvent removal method, soaking it in such as isopropanol and acetone. However, these chemicals have safety risks and irritation. Sexual odor, a threat to the human body and the environment. People are also doing related research. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a UV light-curable water-based resin to solve the problems raised i...
