Preparation process of cleaning fluid for liquid crystal display screen thinning

Abstract

The invention discloses a preparation process of a cleaning fluid for liquid crystal display screen thinning. The preparation process comprises the following steps: S1, selecting raw materials; S2, preparing an auxiliary emulsifier; S3, preparing a cleaning aid liquid; and S4, preparing a waterborne cleaning fluid. The preparation process of the cleaning fluid for liquid crystal display screen thinning is characterized in that a cationic surfactant as a cationic emulsifier and an auxiliary emulsifier which is prepared as a nonionic emulsifier by adding a short-carbon-chain isomeric fatty alcohol polyether to a compound of isomeric alcohol ethoxylate 1309L and linear alcohol ethoxylate AEO-9 are mixed with water, and then added with additives and the cleaning aid to obtain the waterborne cleaning fluid; and the waterborne cleaning fluid has excellent cleaning and emulsifying effects on residual liquid crystals on a liquid crystal display screen with a good cleaning decontamination rate,is non-corrosive to a liquid crystal display screen glass sealant, and has a good cleaning effect on residual glass scraps, finger marks, dust and other dirt on display screen glass.

Description

technical field [0001] The invention belongs to the field of liquid crystal display cleaning, and more specifically relates to a preparation process of a cleaning liquid for liquid crystal display thinning. Background technique [0002] At present, liquid crystal display thinning technologies mainly include grinding and polishing physical methods and chemical methods, and chemical methods are more widely used in actual production, especially wet thinning glass technology. In wet thinning glass technology, acid etching Technology is the most commonly used method. Its main principle is: the mixed acid containing hydrofluoric acid reacts with silicon dioxide and other metal oxides in the glass to remove a layer of skin on the glass surface, thereby achieving the thinning of the glass and its surface. For the purpose of strengthening, after the liquid crystal display is etched and thinned, it is washed with acetone and ethanol in sequence, and then rinsed with deionized water. ...

[0002] At present, liquid crystal display thinning technologies mainly include grinding and polishing physical methods and chemical methods, and chemical methods are more widely used in actual production, especially wet thinning glass technology. In wet thinning glass technology, acid etching Technology is the most commonly used method. Its main principle is: the mixed acid containing hydrofluoric acid reacts with silicon dioxide and other metal oxides in the glass to remove a layer of skin on the glass surface, thereby achieving the thinning of the glass and its surface. For the purpose of strengthening, after the liquid crystal display is etched and thinned, it is washed with acetone and ethanol in sequence, and then rinsed with deionized water. The dust pollution in the workshop and the pollution of liquid crystal dirt such as liquid crystal waste mixed in the air when cleaning the workshop, and even the operator's finger prints on the LCD screen, so it is necessary to transfer the LCD screen to a dust-free workshop for cleaning of the LCD screen. The display screen needs to be cleaned again. Since cleaning with acetone and ethanol can no longer meet the cleaning needs, a specific cleaning solution is required to clean the LCD screen.
