Abstract

The present invention discloses an efficient and environmental-protection liquid crystal display screen cleaning agent, which comprises the following raw materials by weight: 36-44 parts of fatty alcohol polyoxyethylene ether, 18-25 parts of metasilicate, 16-20 parts of glycerol, 8-14 parts of amine alkali, 15-35 parts of a surfactant, 6-9 parts of a chelating agent, and 50-75 parts of deionized water. Compared to the liquid crystal display screen cleaning agent in the prior art, the liquid crystal display screen cleaning agent of the present invention has advantages of low cost, wide raw material source, strong cleaning capability, less consumption, effective metal ion pollution removing, environmental protection and no pollution, cannot damage the integrity of the liquid crystal display screen, and cannot not affect the photoelectric property, the electromagnetic property, the permeability, the device surface physical properties and other performances.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an efficient and environment-friendly liquid crystal display cleaning agent. Background technique [0002] In the manufacturing process of the liquid crystal display, two glass substrates are usually bonded first, leaving a part of the opening, and after filling the liquid crystal, the opening is sealed with a sealant, and then the liquid crystal remaining outside the opening is cleaned. Because liquid crystals are mostly highly polar macromolecular compounds with strong intermolecular forces, they are not easy to disperse in water. Therefore, in the past, organic cleaning agents were generally used to clean residual liquid crystals; organic cleaning agents degrade in the environment Slow, causing great pressure on the environment. Therefore, water-based cleaning agents are gradually developing, but the cleaning power of water-based cleaning agents is weak, and it is not ...
