Preparation process of special soaking treatment liquid for liquid crystal display before thinning

Abstract

The invention discloses a preparation process of special soaking treatment liquid for a liquid crystal display before thinning, comprising the following steps: S1, preparation of raw material, and S2,preparation of soaking liquid; compared with a conventional preparation process of special soaking treatment liquid for a liquid crystal display before thinning, the preparation process of the special soaking treatment liquid for the liquid crystal display before thinning reduces pollutant discharge on the basis of improving treatment effect by using a solution prepared from sodium hydroxide, anhydrous sodium sulphate, triethanolamine, polydimethylsiloxane, ethyl glycoside, polyvinyl alcohol, a complexing agent, hydrochloric acid, organic phosphonate, hydrofluoric acid and pure water; the solution prepared from polydimethylsiloxane, ethyl glycoside and sodium hydroxide, anhydrous sodium sulphate and triethanolamine is highly stable; and when the liquid crystal display is treated, the surface is cleaned more thoroughly, thereby reducing occurrence of pits or concave scratches to affect quality of the product.

Description

technical field [0001] The invention belongs to the field of liquid crystal display thinning treatment liquid, and more specifically relates to a preparation process of special soaking treatment liquid for liquid crystal display before thinning. Background technique [0002] The current market demand makes the liquid crystal display more and more like the ultra-thin direction, so that the liquid crystal display needs to be thinned during preparation, but before the thinning treatment, the surface of the liquid crystal display needs to be soaked , clean the dust, oil stains or other impurities on the surface to avoid pits or scratches on the surface of the LCD screen after thinning, which will affect the quality of the product. At present, the pretreatment solution is mostly a mixed acid solution based on concentrated sulfuric acid. And concentrated sulfuric acid is highly corrosive and easily pollutes the environment. Contents of the invention [0003] The object of the p...
