Embodiment 1
[0031] A preparation method for an acid-resistant ink for integrated touch screen protection, comprising the following steps:
[0032] 1. Weigh 15 parts of shellac resin, 10 parts of acrylic resin, 64 parts of diethylene glycol ether, and 1 part of OP-10 according to the mass fraction and mix them, and heat until the resin is completely dissolved.
[0033] 2. Stir the mixture prepared in step 1 at normal temperature, and discharge 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 hour.
[0035] 4. Add 5 parts of tetrafluoroethylene micropowder into the mixed solution in step 3, stir, and then grind with a three-roll mill to obtain the protective ink.
[0036] The prepared sample is screen-printed on glass, and after curing at 150°C for 15 minutes, it can pass through CNC for 10 minutes without chipping. In ultrasonic (pure water, 55°C) 1h, it will not penetra...
Embodiment 2
[0038] A preparation method for an acid-resistant ink for integrated touch screen protection, comprising the following steps:
[0039] 1. Weigh 30 parts of rosin, 10 parts of epoxy-modified phenolic resin, 41 parts of ethylene glycol ether acetate, and 1 part of lauryl polyoxyethylene ether according to the mass fraction, mix thoroughly, and heat until the resin is completely dissolved.
[0040] 2. Stir the mixture prepared in step 1 at normal temperature, and discharge 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, and stir at room temperature for 1 hour.
[0042] 4. Add 10 parts of tetrafluoroethylene micropowder into the mixed solution in step 3, stir, and then grind with a three-roll mill to obtain the protective ink.
[0043] The prepared sample is screen-printed on glass, and after curing at 150°C for 15 minutes, it can pass through CNC for 15 minutes without chipping. In ultr...

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 ink, in particular to an acid-resistant ink for integrated touch screen protection and a preparation method thereof. Background technique [0002] Integrated touch (OneGlassSolution, OGS) technology refers to the technology of directly forming ITO conductive film and sensor on the protective glass, and a piece of glass plays the dual role of protective glass and touch sensor at the same time. The glass processed by OGS technology is cut to obtain 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 save a bonding process in the production process, which is beneficial to reduce production costs and improve product yield. Moreover, the obtained OGS touch screen has the characteristics of lightness, thinness, good light transmission and the like. However, after the glass is cut, it is easy to produce cracks at the cutting...
