Abstract

The invention relates to a vitreous etching bath, which comprises 0.5%-8% microcosmic salt, 0.5%-8% pyrophosphate, 0.01%-0.5% inorganic alkaline, 5%-45% surface activator and 39%-93% water. The preparing method comprises the following steps: adding the microcosmic salt and the pyrophosphate in the water, heating in order to dissolve; adding inorganic alkaline and non-ionic surface activator and mixing. The invention can remove greasy dirt, fingerprint, particles and sio2 for buffed glass base plate, which can removes the impurity and Ceo2 on the glass, achieves the request of the environmental protection.

Description

(1) Technical field: [0001] The invention relates to an etching solution and a preparation method thereof, in particular to a glass etching solution and a preparation method thereof. (two) background technology: [0002] Liquid crystal display (LCD) has now expanded from watches and calculators to various aspects such as instruments, communication equipment, and notebook computers. After the upper and lower conductive glass is made into a liquid crystal cell, an appropriate voltage signal is applied to these electrodes, so that the liquid crystal molecules with dipole moments are arranged in a specific way under the action of an electric field, thus showing the wavelength corresponding to the electrode wavelength. graphics. [0003] Among the oxide conductive films, the ITO conductive film has the highest light transmittance and the best electrical conductivity, and it is easy to etch fine patterns in acid solution. The ITO conductive thin film needs to be plated on the gl...
