Embodiment 1

[0013] 1. Prepare the required raw materials according to the following parts by weight:

[0014] Polyurethane Acrylic Resin 25, Acrylated Acrylic Resin 35, Hydroxyethyl Methacrylate 5, 1,6 Ethylene Glycol Diacrylate 6, Dipentaerythritol Hexaacrylate 3, Photoinitiator 10, Toner 6, Meteorological Silica 3. Defoamer 2, dispersant 2, silane adhesion promoter 3.

[0015] 2. The specific configuration steps are as follows:

[0016] 1) Feed polyurethane acrylic resin, acrylated acrylic resin, hydroxyethyl methacrylate, 1,6 ethylene glycol diacrylate, and dipentaerythritol hexaacrylate according to the number of parts, stir for 5 minutes until uniform, and the stirring speed is 800-1000 rpm;

[0017] 2) Slowly add photoinitiator, defoamer, and dispersant according to the number of parts, and stir for 10-15 minutes at a stirring speed of 800-1000 rpm;

[0018] 3) Add the toner according to the number of parts, stir for 10-15 minutes, and the stirring speed is 1000-1500 rpm.

[001...

Embodiment 2

[0032] Polyurethane acrylic resin 25, acrylated acrylic resin 35, hydroxyethyl methacrylate 5, 1, 6 ethylene glycol diacrylate 6, dipentaerythritol hexaacrylate 5, photoinitiator 13, toner 2, meteorological silica 3, defoamer 2, dispersant 2, silane adhesion promoter 2

[0033] The specific configuration steps are the same as in Embodiment 1;

[0034] Printing and drying conditions are identical with embodiment 1;

[0035] The deinking method is the same as in Example 1.

[0036] The UV glass protection ink prepared in this embodiment is used to protect the touch screen glass in the process. In the deinking stage, the ink is not completely removed within 3-5 minutes, and the glass still remains. The test result shows that the glass is scratched at 1%. Contamination of 6%, compared with the traditional process, the rate of good products increased by 35%.

Embodiment 3

[0037] Example three polyurethane acrylic resin 25, acrylated acrylic resin 30, hydroxyethyl methacrylate 4, 1,6 ethylene glycol diacrylate 9, dipentaerythritol hexaacrylate 12, photoinitiator 8, toner 3, weather Silica 2, defoamer 3, dispersant 2, silane adhesion promoter 1

[0038] The specific configuration steps are the same as in Embodiment 1;

[0039] Printing and drying conditions are identical with embodiment 1;

[0040] The deinking method is the same as in Example 1.

[0041] The UV glass protection ink prepared in this example is used to protect the touch screen glass during processing. In the CNC stage, the edge of the ink is slightly off, and the inspection result is 13% scratched, which is 27% higher than the traditional process. .

Abstract

The invention discloses ultraviolet (UV) glass protective printing ink and a manufacturing method thereof. The printing ink comprises, by weight, 25-50 parts of urethane acrylate resin, 20-45 parts of acrylate crylic acid resin, 1-10 parts of hydroxyethyl methylacrylate, 1-10 parts of 1,6-ethylene acrylic acid ester, 1-8 parts of dipentaerythritol hexaacrylate, 6-12 parts of photoinitiators, 3-18 parts of toner, 1-4 parts of gas-phase silica, 2-5 parts of antifoaming agents, 2-5 parts of dispersing agents, and 1-3 parts of silane attaching accelerant. The components are added in sequence according to parts thereof, stirring is carried out at constant speed for full time, then grinding is carried out through a three-roller machine, and finally the printing ink can be obtained by filtering a solution. In a glass machining process of a touch screen, silk screen is carried out on the surface of glass for protection with the UV glass protective printing ink, final perfectness rate of glass products is improved by 27%-40% compared with the situation when a glass protective measurement is not taken, resource waste can be obviously reduced, enterprise manufacturing cost is lowered, and enterprise production capacity is improved.

Description

technical field [0001] The invention relates to a UV ink, in particular to a touch screen glass protection UV ink, and also discloses a preparation method of the ink. technical background [0002] The existing touch screen glass processing technology, from slitting, profiling, CNC, to polishing, etc., is very easy to cause a certain degree of scratches on the glass in the machine or other operations, and the scratch rate is generally above 42%. These scratches often need to be eliminated by flat grinding in the follow-up process; for serious scratches, the product can only be scrapped if it cannot be eliminated by flat grinding; and the rare earth polishing used in the flat grinding process The price of powder has soared by nearly 20-30 times; the average grinding time for each piece of glass is 30-60 minutes. The above factors have caused a lot of waste of resources, greatly increased the manufacturing cost of the enterprise and seriously restricted the production capacity...
