Embodiment 1

[0025] The mass percentage is 10% phenolic resin (Benxi Ruishida Co., Ltd., Liaoning Province), 2% silicon dioxide nanoparticles, 10% ethanol, 1% glycerin, 77% ethylene glycol monomethyl ether mixed, Stir at room temperature for 4 hours, after the resin is completely dissolved, add zirconium beads and ball mill for 48 hours, use a 0.1 micron filter to remove insoluble matter and / or impurities in the ball milling liquid, and silica nanoparticles with a particle size greater than 100nm, and obtain the filtrate Abrasion-resistant ink for inkjet-to-plate technology.

Embodiment 2

[0027] 30% organic silicon resin (Xinchuan Chemical Industry (Tianjin) Co., Ltd.), 10% silicon dioxide nanoparticles, 30% ethylene glycol, 10% glycerin, 20% ethylene glycol monoethyl ether Mix, stir at room temperature for 6 hours, add zirconium beads and ball mill for 48 hours after the resin is completely dissolved, use 0.1 micron filter membrane to remove insoluble matter and / or impurities in the ball mill liquid, and silica nanoparticles with a particle size greater than 100nm, to obtain The filtrate is an abrasion-resistant ink for inkjet-to-plate technology.

Embodiment 3

[0029] 20% by mass percentage of phenolic resin and silicone resin, 5% of titanium dioxide nanoparticles, 20% of ether, 5% of propylene glycol, 50% of ethylene glycol monomethyl ether were mixed, stirred at room temperature for 6 hours, until the resin was completely After dissolving, add zirconium beads and ball mill for 48 hours, and use a 0.1 micron filter membrane to filter out insoluble matter and / or impurities in the ball milling liquid, as well as silica nanoparticles with a particle size greater than 100nm. The obtained filtrate is used for inkjet direct plate making technology wear-resistant ink.

Abstract

The invention discloses a hard-wearing ink for ink-ejecting direct plate-making technique in ink domain, which comprises the following steps: mixing 10%-30% cross linkable resin, 2%-10% silica dioxide or titanium oxide inorganic nanometer particle, 10%-30% fast-drying solvent, 1%-10% humectant and 20%-77% main body dissolvent; grinding; filtering; removing insoluble matter, impurity, silica dioxide with grain diameter more than 100nm or titanium oxide inorganic nanometer particle in balling liquid; getting the ink. This ink can increases abradability of paint and can get high quality ink-ejecting CTP plate, which possesses good abradability and image resolution.

Description

technical field [0001] The invention belongs to the field of ink, relates to an ink with good wear resistance and image resolution, and more particularly relates to a wear-resistant ink which can be used for direct spraying to prepare plate materials in inkjet direct plate making (CTP) technology. Background technique [0002] Inkjet CTP technology is a technology that uses inkjet printing equipment to directly spray images on the plate base. Compared with laser imaging and thermal imaging, the biggest disadvantage of inkjet platemaking technology is its limited resolution and imaging quality. Therefore, it is very important for the research of inkjet printer or plotter ink. At present, there are two ways to use inkjet CTP: one is to spray ink directly on the blank plate for imaging, which is cheap and simple. The ink used can be water-soluble ink solution, thermosetting ink, ultraviolet (UV) curing ink etc., but the printing capacity of the plate material is 10,000 to 20,0...
