Problems solved by technology

[0007] Disadvantages of peelable glue on the market: (1) There will be residual glue when peeling off, and it needs to be wiped with solvent
(2) After UV protection ink is processed, it needs to be soaked in alkaline water to remove it, which will damage the sensor part
(3) Poor high temperature resistance, especially in OGS processing. Due to the poor temperature resistance of the peelable rubber, the yield rate of related products using OGS technology becomes lower
(4) The inks currently on the market have poor acid resistance and are not easy to remove the film. Cleaning requires alkaline water, which will damage the sensor part

Abstract

The invention discloses acid-proof ink for protecting an integrated touch screen and a preparation method of the acid-proof ink. The acid-proof ink comprises components A to F. The component A contains polystyrene-polyurethane-unsaturated polyester resin; the polystyrene-polyurethane-unsaturated polyester resin is synthesized by virtue of a molecular design, and a controllable design of the structure and properties of a material is realized. A three-dimensional network structure is formed by virtue of chemical reaction between the film-forming components A and B, so that the acid resistance and the high temperature resistance of the ink, and the strippability of a film can be improved, and the protection effect of the ink to a substrate can be enhanced; (2) the acid corrosion resistance of the ink is further improved. The protective ink is excellent in acid resistance, excellent in film-forming property and excellent in film adhesion, and can be stripped completely after use; besides, the ink is excellent in high temperature resistance.

Description

technical field [0001] The invention relates to an ink for OGS, in particular to an acid-resistant ink for protecting an integrated touch screen and a preparation method thereof. Background technique [0002] As a high-strength, scratch-resistant glass, touch screen cover glass is widely used in high-end smartphones, tablet computers, flat-panel TVs, and industrial and commercial touch screens. OGS is one of the future development directions of the touch screen industry. 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 proc...
