Problems solved by technology

Although this compound system is beneficial to accelerate the removal of window glass ink, the technical difficulty is how to keep this deinking agent containing organic solvents from delamination and stable performance during long-term continuous heating
At the same time, another technical difficulty of the existing system is how to reduce the corrosion of window glass in high-concentration acid-base solutions

Abstract

A display window glass deinking agent, the components include: 30-70% of water, 5-20% of inorganic alkali, 0.5-8% of inorganic corrosion inhibitor, 7.5-16% of organic corrosion inhibitor, and 5-20% of solvent , 5-20% of penetrating agent, and 7-22% of the mixture composed of alkyl alcohol ether polycarboxylate, alkyl polyoxyethylene phosphate and cocoyl glucoside is added. The deinking agent of the present invention can keep the solution from delamination all the time during heating and use, has stable performance and long service life; due to the addition of corrosion inhibitor, the glass deinking agent of the present invention has little corrosion to the glass substrate during use, It is not easy to scratch the window glass, and improves the yield rate of the flat panel display window glass after deinking; meanwhile, the deinking agent of the present invention has strong permeability, moderate alkalinity, and fast ink removal speed.

Description

technical field [0001] The invention relates to a product for removing ink from display window glass, in particular to a deinking agent for flat panel display window glass. Background technique [0002] As a basic component of liquid crystal display devices, window cover glass is one of the key basic materials for the flat panel display industry. In recent years, with the continuous growth of the flat panel display industry, especially mobile smartphones, tablet computers, car touch, players, touch appliances, wearable smart devices and digital cameras, the annual shipments of window glass Showing a momentum of rapid growth. Since the window glass belongs to the category of touch-sensitive electronic display glass, it has extremely high requirements on the physical and chemical characteristics, optical properties and processing technology of the glass. However, the protective glass for the window will inevitably appear in the production process, especially the screen printi...
