UV curing ink for optic glass silk screen

Abstract

The invention discloses UV curing ink for optic glass silk screen, which comprises the following components in parts by weight: 4-7 parts of acyl phosphorus oxide, 7-13 parts of modified acrylic resin, 8-16 parts of organosilicone modified bisphenol A-type epoxy resin, 8-16 parts of methacrylic acid dimethylamino ethyl ester, 30-40 parts of rutile titanium oxide, 20-30 parts of ethylene glycol monoethyl ether acetate, 0.5-2 parts of organic silicon defoamer, 0.5-2 parts of hydroquinone, 0.5-2 parts of acrylate copolymer, 0.5-2 parts of benzalacetone, 0.5-2 parts of neovadine and 0.5-2 parts of screen photogelatin. Compared with the prior art, the problem of low printing efficiency caused by that common ink has to be subjected to high-temperature baking before entering next printing is solved, and the printed common ink only needs to be subjected to about 30-second UV curing before being put into production, so that continuous silk screen automation is realized.

Description

technical field [0001] The invention relates to an ink, in particular to a UV curable ink for lens glass screen printing. Background technique [0002] In the silk screen printing process of optical lens glass, the industry generally uses solvent inks. Solvent inks have strong bonding force with glass and good gloss. The development of inks is mature and is in its heyday. However, the defects of solvent ink are also obvious: 1. After each printing is completed, it needs to be baked at high temperature for more than 5 minutes before the next printing can be continued, resulting in discontinuous production and bringing difficulties to industrial automation; 2. Because of the need for baking, The oven needs to occupy an area, and the heat is high, which affects the screen printing environment and wastes air-conditioning energy; 3. The operator works by the oven for a long time, and the working environment is poor. 4. When the product is baking, there will be dust and impuritie...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: aiming at the problem that the printing efficiency is low due to the low printing efficiency caused by the high-temperature baking process of the existing common solvent ink used for optical lens glass screen printing before it can enter the next printing, it provides a printing method that only needs to be processed after printing. A kind of UV curing ink for lens screen printing can be put into the next production after UV curing of about 30S, so as to realize the continuous automation of screen printing
