Problems solved by technology

When the photopolymerization system is cured in the air, the oxygen in the air will make the photo-cured surface not completely cured and sticky, which seriously affects the overall performance of the photo-cured material, especially the volume shrinkage after curing affects adhesion, hardness, etc. question

Abstract

The invention discloses a method for preparing a UV printing material for an intelligent blackboard, comprising the following steps: (1) adding the aliphatic polyurethane triacrylate, 1,6 hexanediol diacrylate, ethylene glycol diacrylate in parts by weight Glycidyl ether, castor oil polyglycidyl ether and alkyl-modified organosiloxane are mixed in a stirring disperser to obtain material 1; (2) adding the stated weight of hydroxytoluene to material 1 obtained in step (1) Butyl ester, organic thermosetting polymethylurea resin, 4‑acryloylmorpholine, 2‑hydroxy‑2‑methyl‑1‑phenyl‑1‑acetone, sulfonyloxyketone and coloring pigment, continue mixing to obtain material 2; (3) Send the material 2 obtained in step (2) to a bead mill and grind it to a particle size of 300-400nm to obtain a UV printing material. The UV printing material prepared by the invention can be cured without too much heat energy, effectively avoids the oxygen inhibition phenomenon of the UV printing material, and has high printing precision.

Description

technical field [0001] The invention relates to a method for preparing consumables for UV printing, in particular to a method for preparing UV printing materials. Background technique [0002] UV light curing technology has the advantages of fast curing speed, high production efficiency, good mechanical and physical properties, less pollution, energy saving, etc., and is known as a green technology. With the increasing emphasis on environmental protection and the development of science and technology, the UV curing market is developing rapidly and is widely used in coatings, adhesives, inks, electronic packaging, glass, dental restoration, photolithographic imaging, and biomedicine. Although UV curing technology has made a lot of progress, there are still some problems in application, such as serious oxygen inhibition phenomenon in the existing UV curing system, low curing hardness, high viscosity and poor stability. [0003] Oxygen inhibition refers to the phenomenon that ...
