Abstract

The invention discloses UV curing ink for printing of digital product touch screen glass, which is characterized in that the ink is prepared from the following raw materials in parts by weight: 1-3 parts of organic pigments, 20-24 parts of methacrylate, 12-15 parts of epoxy methacrylate, 2-3 parts of ammonium molybdate, 1-2 parts of chromium oxide, 1-2 parts of morpholine, 5-8 parts of glycol ether, 1-2 parts of ferrocene, 3-4 parts of 2-butoxyethanol, 3-4 parts of methacrylic acid, 10-14 parts of diethylene glycol monoethyl ether acetate, 5-8 parts of benzil dimethyl ketal, 6-9 parts of tripropylene glycol diacrylate, 5-8 parts of a 184 photoinitiator, 1-2 parts of an antioxidant DSTP, 1-2 parts of Sb2O3, 1-2 parts of barium metaborate and 4-5 parts of an accessory ingredient. According to the invention, the toughness of the ink is improved through the accessory ingredient, the ink is enabled to be uniformly dispersed, and the stability of the ink is maintained; the UV curing ink is high in curing speed, reduces energy consumption and time, improves the production efficiency, and is suitable for large scale production.

Description

A kind of UV curing inks for digital product touch-screen glass printing and preparation method thereof

Technical field

The present invention relates to a kind of ink and preparation method thereof, particularly a kind of UV curing inks for digital product touch-screen glass printing and preparation method thereof.

Background technology

Silk screen printing is that silk fabrics, synthetic fabrics or wire cloth are stretched tight on screen frame, adopts manual method of carving paint film or photochemistry plate-making to make screen printing forme.Modern screen printing technique, to utilize sensitive materials by photomechanical method, to make the flat carriers such as screen printing forme (making the silk screen hole of picture and text part on screen printing forme is through hole, and the silk screen hole of non-graphic part is plugged) oil painting, etching, pictorial poster, business card, binding and layout front cover, commodity packaging, product tag, dyeing textile product, touch-screen glass and metal etc.Ink is the screen printing ink that is conducive to two liquid response types of environment, essential superior printing stability while thering is touch screen glass printing, good sticking power and patience, filming after solidifying has good sticking power, water tolerance and chemoresistance, also has higher surface hardness and wear resistance simultaneously.

Summary of the invention

The object of this invention is to provide a kind of UV curing inks for digital product touch-screen glass printing and preparation method thereof.

In order to realize object of the present invention, the present invention passes through following scheme implementation:
