Embodiment 1
[0031] The preparation method of acid resistant ink for integrated touch screen protection includes the following steps:
[0032] 1. Weigh 15 parts of shellac resin, 10 parts of acrylic resin, 64 parts of diethylene glycol ethyl ether, and 1 part of OP-10 according to the mass fraction, and heat until the resin is completely dissolved.
[0033] 2. The mixture prepared in step 1 is stirred at room temperature, and discharged when the temperature is cooled to room temperature.
[0034] 3. Add 5 parts of amino resin to the mixed emulsion prepared in step 2, and stir at room temperature for 1 h.
[0035] 4. Add 5 parts of tetrafluoroethylene micropowder to the mixed liquid of step 3 and stir, and then grind through a three-roll mill to obtain the protective ink.
[0036] The prepared sample was silk-printed on the glass and cured at 150°C for 15 minutes. After CNC time, it could not collapse for 10 minutes. In the ultrasonic wave (pure water, 55°C), it will not penetrate into the glass for...

[0038] The preparation method of acid resistant ink for integrated touch screen protection includes the following steps:
[0039] 1. Weigh 30 parts of rosin, 10 parts of epoxy-modified phenolic resin, 41 parts of ethylene glycol ethyl ether acetate, and 1 part of polyoxyethylene lauryl ether according to mass fraction and mix thoroughly, and heat until the resin is completely dissolved.
[0040] 2. The mixture prepared in step 1 is stirred at room temperature, and discharged when the temperature is cooled to room temperature.
[0041] 3. Add 8 parts of 2MA-OK curing agent to the mixed emulsion prepared in step 2, the stirring temperature is room temperature, and the time is 1h.
[0042] 4. Add 10 parts of tetrafluoroethylene micropowder to the mixed liquid of step 3 and stir, and then grind through a three-roll mill to obtain the protective ink.
[0043] The prepared sample was silk-printed on the glass and cured at 150°C for 15 minutes. After CNC time, it could not collapse for 15 minu...

Abstract
The invention provides acid-proof ink for protecting one glass solution (OGS) touch screens and a preparation method thereof, relating to ink. The acid-proof ink comprises 1-8 parts of curing agent, 5-50 parts of resin, 10-80 parts of solvents, 1-5 parts of emulsifier and 5-30 parts of filler by mass. The preparation method comprises the following steps: mixing natural resin, synthetic resin and the solvents, adding the emulsifier and heating the materials until the natural resin and the synthetic resin are totally dissolved, thus obtaining a mixture; stirring the prepared mixture under normal temperature and discharging the material when the temperature is cooled to the room temperature, thus obtaining mixed emulsion; adding the curing agent to the prepared mixed emulsion, adding the filler after stirring the materials and grinding the mixture, thus obtaining the liquid acid-proof ink for protecting OGS touch screens. The acid-proof ink has the advantages and technical effects that the ink has smaller particles and denser film, so that the ink can not permeate even if being strengthened; the ink has high particle packing density and is 5-10mu m thinner than the printing thickness of common protective ink; the stability of viscosity of the ink in the printing process can be maintained and the ink does not become dry easily, has good printing effects and does not stick to screen printing plates.
Description
Technical field [0001] The invention relates to an ink, in particular to an acid-resistant ink for protecting an integrated touch screen and a preparation method thereof. Background technique [0002] The integrated touch (OneGlassSolution, OGS) technology refers to the technology of directly forming an ITO conductive film and sensor on the protective glass. A piece of glass simultaneously plays the dual role of the protective glass and the touch sensor. The glass processed by OGS technology is cut to obtain an OGS touch screen. Compared with the traditional G / G touch technology, OGS technology has many advantages. For example, it can save a piece of glass substrate, and it can save a bonding process in the production process, thereby helping to reduce production costs and improve product yield. Moreover, the obtained OGS touch screen has the characteristics of lightness, thinness, and good light transmittance. However, after the glass is cut, cracks are prone to occur at the c...
