Problems solved by technology

[0004] In order to solve the problem of high-speed printing ink coating anti-sticking, those skilled in the art have proposed various solutions, such as in "A UV gravure RFID ink and its preparation method", the authorization number is CN 102850848B In the invention patent It has been found that adding hydrocarbon resin into the UV system can improve the surface drying effect, but the production process needs to be heated to 100-150°C, which will easily cause system instability and low boiling point substances to volatilize, and the produced ink will be printed after being ground by a sand mill High gloss, no matte anti-sticking function, unable to further increase winding speed

Embodiment 1～8

[0028] Embodiment 1-8 provides a kind of rapid printing anti-etching ink, and the corresponding raw material components and parts by weight of each composition are as shown in Table 1, and the preparation method is as follows:

[0029] Put the acrylate monomer and saturated polyester resin into a stainless steel reaction kettle, stir at 500rpm at 70°C until completely dissolved and then lower to room temperature; then add half of the dispersant and stir evenly, add the pigment and stir at a high speed at 2000rpm until Disperse evenly, and then use a sand mill to grind to prepare a color paste; put carboxyl-modified epoxy acrylate and carboxyl-modified polyester acrylate into a stainless steel reaction kettle, add the other half of the dispersant and stir until uniform, add gas phase two The silicon oxide is stirred at a high speed of 2000rpm to disperse evenly; finally, the above-prepared color paste and initiator are added, and stirred at a medium speed of 1000rpm to obtain a ...

Abstract

The invention provides a rapid printing etching-resistant ink. The rapid printing etching-resistant ink comprises, by weight, 30-60 parts of carboxyl modified epoxy acrylate, 7-30 parts of carboxyl modified polyester acrylate, 4-8 parts of saturated polyester resin, 20-40 parts of an acrylate monomer, 5-10 parts of a photoinitiator, 0.5-5 parts of an adhesion promoter, 0.5-2 parts of fumed silica,1-2 parts of a pigment and 0.1-1 part of a dispersing agent. The anti-etching ink is high in printing speed, and has the advantages of excellent anti-sticking effect, good acid etching resistance andadjustable alkali liquor film stripping speed.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a rapid printing anti-etching ink. Background technique [0002] In the production methods of circuit board printing, metal etching and radio frequency electronic tags, the circuit pattern produced by metal etching method has high circuit precision, good stability, long service life, good flexibility, high and low temperature resistance, moisture resistance and strong corrosion resistance. And other advantages, and easy to achieve mass production, it is the preferred process for circuit production at this stage. [0003] Anti-etching inks are usually printed on metal substrates by gravure printing or silk screen printing to protect printed circuit patterns. If the printing speed of the anti-etching ink is too fast, the ink will not cure well, and the ink will easily stick to the back of the substrate during the subsequent winding or stacking process, resulting in defective prod...
