Problems solved by technology

[0003] At present, there are many protections for touch screen cover glass or ITO glass. The traditional ones, such as peelable protective glue / protective film, can play a protective role in the process of processing, but they need to be peeled off manually, which consumes a lot of manpower and reduces the process efficiency. Low
Printing ink is currently the most important way to protect the best touch screen cover glass or ITO glass, but most of them have disadvantages such as not easy to remove the film and difficult to clean
Although there have been some inventions that can be washed off with hot acid and alkali solutions or removed by high-temperature hot water, the film removal speed is relatively slow, generally 2 to 5 minutes, which increases the cost of film removal on the one hand, such as purchasing treatment liquid, heating water On the other hand, acid, lye, etc. may also be corrosive to the touch screen cover glass or ITO glass itself, and may also cause health damage to the operator

Embodiment 2

[0060] A washable touch screen temporary protection ink, first equipped with a water-based acrylic modified epoxy resin aqueous solution with a solid content of 40%, and a starch aqueous solution with a solid content of 5%, and then weighed according to the mass ratio:

[0061]

[0062] Add the above-mentioned polyacrylic acid resin aqueous solution, XH-103Z leveling agent, and nano silicon dioxide into the disperser and stir at 400r / min for 10min until uniform, then add other remaining raw materials and stir at 300r / min for 50min to obtain ink.

[0063] The obtained ink was printed with a 200-mesh screen brush on a 10 μm coating film on the above-mentioned touch screen cover glass and ITO glass, first dried at 80°C for 30 minutes, and then placed in an oven at 200°C for 2 hours before testing. The hardness tested by the GB / T6739 method is B, and the film is smooth and yellowish. The effect of film removal in 50°C water is about 90s and it falls off in pieces.

Embodiment 3

[0065] A washable touch screen temporary protection ink, first equipped with a water-based amino resin aqueous solution with a solid content of 40%, and an aqueous solution of sodium alginate with a solid content of 5%; then weighed according to the mass ratio

[0066]

[0067] Add the above-mentioned polyacrylate emulsion and XH-103Z leveling agent into the disperser and stir at 400r / min for 15min until uniform, then add other remaining raw materials and stir at 300r / min for 60min to obtain the ink.

[0068] The obtained ink was printed with a 200-mesh screen brush on a 10 μm coating film on the above-mentioned touch screen cover glass and ITO glass, first dried at 80°C for 30 minutes, and then placed in an oven at 200°C for 2 hours before testing. The hardness tested by the GB / T6739 method is B, the film is smooth and light yellow, and the effect of film removal in 50°C water is about 50s, and it will fall off in large blocks.

Abstract

The invention discloses washable touch screen temporary protection ink as well as a preparation method and application thereof. The washable touch screen temporary protection ink consists of the following raw materials by weight percent: 0 to 50 percent of polyacrylic acid resin solution, 5 to 90 percent of water-based paint resin, 5 to 50 percent of water-soluble macromolecule solution, 0 to 70 percent of polyacrylate emulsion, 1 to 10 percent of packing, 0.1 to 2 percent of pigment and 2 to 5 percent of functional additive, wherein the polyacrylic acid resin solution and the polyacrylate emulsion are not simultaneously equal to 0. When in preparation, a polyacrylic acid solution, the polyacrylate emulsion, a water-based leveling agent and packing are placed into a dispersion machine and uniformly mixed, and then the other components are placed into the dispersion machine to be uniformly mixed to obtain the washable touch screen temporary protection ink. The ink can protect touch screen cover plate glass or an ITO glass surface layer film against damage during a construction process at a high temperature of 200 DEG C; moreover, after the ink is used at 200 DEG C, the ink can fall off in block shapes in 30s to 2min after being soaked in water with the temperature of 50 DEG C.

Description

technical field [0001] The present invention relates to the field of ink, specifically a kind of ink that can temporarily protect the surface of the touch screen cover glass or ITO glass during the processing of the touch screen, especially at a high temperature of 200°C. An ink that can be washed off in warm water at a very fast speed after the construction of the control screen cover glass or ITO glass and its preparation method. technical background [0002] With the continuous development of touch screen technology, its related industries have developed rapidly, such as smart phones, tablet computers, navigators, ATMs, etc., and have penetrated into every field of life, which has greatly changed people's way of life. However, the touch screen cover glass or ITO glass in the unprotected state is easy to be damaged to a certain extent during the subsequent cutting, edging or other processing processes, especially under high temperature conditions. The damage is more obviou...
