Problems solved by technology

During the filling process, liquid crystals will remain on the surface of the liquid crystal box, PIN pins and slits, if not removed, it will seriously affect the appearance, display performance and even life of the product, or cause circuit failure
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 detergents were generally used to clean residual liquid crystals; organic detergents degrade in the environment Slow, causing great pressure on the environment. Therefore, it is gradually developing towards water-based cleaners, but the cleaning power of water-based cleaners is weak, and it is not easy to clean the residual liquid crystal.

Abstract

The invention discloses a cleaning agent for a liquid crystal display screen, belonging to the technical field of cleaning agents. The cleaning agent comprises the following raw materials by mass: 5-10% of fatty alcohol polyoxyethylene ether, 2-5% of isomeric alcohol polyoxyethylene ether, 0.2-0.5% of a fluorocarbon surfactant, 3-7% of sodium diisooctyl succinate, 2-5% of sodium dodecyl benzene sulfonate, 1-3% of cocamidopropyl betaine, 2-5% of trans-1,2-cyclohexanediaminetetraacetic acid, 1-3%of sodium polyacrylate, 2-4% of sodium metasilicate, 2-5% of hydroxyethylethylenediamine, 1-3% of polyvinyl alcohol, 3-7% of a solubilizer and 0.5-1% of a corrosion inhibitor, with the balance being deionized water. The cleaning agent of the invention has good ability in dissolving of liquid crystalmaterials, oil stains, dust, etc., and liquid crystal materials, oil stains, dust and the like are emulsified and dispersed in the cleaning agent and are thus separated from a to-be-cleaned surface; and the cleaning agent has good cleaning effect, is free of residues on the surface of a liquid crystal cell and low in corrosivity to liquid crystal display screens, and does not affect the physical properties of liquid crystal display screens.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a cleaning agent for liquid crystal display screens. 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 the opening is sealed with a sealant after filling the liquid crystal. During the filling process, liquid crystals will remain on the surface of the liquid crystal cell, PIN pins and slits. If not removed, it will seriously affect the appearance, display performance and even life of the product, or cause circuit failure. 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 detergents were generally used to clean residual liquid crystals; organic detergents degrade in the environment Slow, causing great pressure on the environ...
