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

The invention discloses a deinking agent for display window glass. The deinking agent is prepared from 30-70% of water, 5-20% of inorganic base, 0.5-8% of inorganic corrosion inhibitors, 7.5-16% of organic corrosion inhibitors, 5-20% of solvent and 5-20% of penetrant, and 7-22% of mixtures composed of alkyl alcohol ether polycarboxylate, alkyl polyoxyethylene phosphate and coco glucoside are added. In the heating application process, the deinking agent is capable of preventing a solution from being layered all the time, stable in performance and long in service life; due to the fact that the corrosion inhibitors are added, in the application process of the glass deinking agent, little corrosion is caused to a glass base plate, it is not easy to scratch the window glass, and the yield rate of the panel display window glass obtained after the deinking is raised; meanwhile, the deinking agent is great in penetrability, moderate in alkalinity and high in 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...
