Abstract

The invention discloses an etching solution used for cleaning electronic liquid crystal screens, and belongs to the technical field electronic liquid crystal screen cleaning. The etching solution comprises, by weight, 25 to 30% of hydrogen peroxide, 5 to 10% of hydrofluoric acid, 1 to 5% of phosphoric acid, 5 to 10% of a surfactant, 1 to 3% of a water purifying agent, and the balance high purity water. A preparation method comprises following steps: the components are weighed accurately, high-purity water is introduced into a reaction kettle, the surfactant and hydrogen peroxide are added, anobtained mixture is stirred for 50-70min, hydrofluoric acid is added, an obtained mixed solution is stirred for 50-70min, phosphoric acid is added for 120 to 140min of stirring, and at last the waterpurifying agent is added for 25 to 35min of stirring, so that the etching solution used for cleaning the electronic liquid crystal screens is obtained after qualified detection. The beneficial effectsare that the cleaning capacity is better than that of similar products, the cleaning time is short, the cleaning effect is better, and the etching solution is an environmentally friendly product.

Description

technical field [0001] The invention relates to an etchant for cleaning electronic liquid crystal screens, belonging to the technical field of cleaning liquid crystal screens. Background technique [0002] With the development of the economy and the improvement of living standards, the size of the screens of LCD TVs, computers, and mobile phones used by people is also increasing day by day, and the dust, oil stains and other dirt formed on the screen by electrostatic adsorption are more obvious. A scientific study shows that bacteria such as Staphylococcus and Escherichia coli carried on mobile phones are 18 times that of toilets. Therefore, the single-function screen cleaners currently on the market that only clean surface dirt can no longer meet people's higher demand for a healthy life. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides an etching solution for cleaning electronic liquid crystal scr...
