No-solvent ultraviolet curing glass printing ink and preparation method thereof

The invention relates to a no-solvent ultraviolet curing glass printing ink and a preparation method thereof; the ink takes high-tractility photochemical active polyester acrylic ester as main ingredient, takes initiator and assistant initiator as curing agents and takes defoamer and flatting agents as auxiliary materials, and then inorganic or organic pigment is mixed, and a functional acrylic ester activated monomer is used as a viscosity regulator; the proportion of the ingredients of the no-solvent ultraviolet curing glass printing ink is as follows: 20-60 parts of multi-functional polyester acrylic ester, 3-8 parts of initiators, 2-5 parts of assistant initiator, 1-3 parts of defoamers, 0-1 part of flatting agent, 8-50 parts of inorganic pigments, 8-15 parts of organic pigments and 10-30 parts of functional acrylic ester activated monomers; the preparation method comprises batching, rolling dispersion and tempering steps; the no-solvent ultraviolet curing glass printing ink has the advantages that: 1. the ink is a 100-percent curing system, has no solvent volatilization and is harm to human body. 2. the curing performance is good, two mercury high pressure lamps with 80-120w/cm are adopted, and complete curing can be realized within 3-6 seconds. 3. the activated monomer is used to regulate the system viscosity, the ink is applied to pad transferring or silk-screen printing, and the universality is strong.
