Problems solved by technology

[0003] The existing deinking agents and deinking methods mainly include: 1) Removal of halogen-containing and benzene-containing solvents: this method takes a long time to remove, and the solvent volatilizes a large amount, which has a great adverse effect on the environment and the health of the operator ; 2) Removal by alkali boiling: This method has high energy consumption and higher requirements for equipment, and has been gradually eliminated; 3) Common deinking agent removal: This deinking agent is used more now, and it needs to be used during use. Heating to 80 ℃ ~ 90 ℃, the effect is good for single-layer ink (black ink), but the effect is poor for multi-layer ink, especially in the process of heating or high temperature use, delamination is easy to occur, and the performance is unstable, so it cannot meet the requirements of glass detachment. ink request

Abstract

The invention relates to the technical field of deinking agents, in particular to an environment-friendly deinking agent for toughened glass and a preparation method of the environment-friendly deinking agent. The deinking agent is prepared from 30%-70% of deionized water, 0.5%-8% of a corrosion inhibitor, 5%-15 % of a penetrant, 5%-20% of an inorganic basic compound, 5%-15 % of an aqueous stabilizer, 5%-20% of a solvent and 5%-15% of a mixture of alkyl alcohol ether carboxylate and alkyl polyoxyethylene phosphate. The raw materials of the deinking agent are all environment-friendly agents, and halogen, benzene and other toxic solvents are not contained; screen printing ink on the toughened glass of various tablets, touch screens and the like is removed under the synergistic effect among the components of the deinking agent, the deinking effect is good, and the deinking speed is high; besides, the homogeneous phase can be kept and a solution does not layer in a heating or high-temperature use process, and the chemical performance of the deinking agent is more stable.

Description

technical field [0001] The invention relates to the technical field of deinking agents, in particular to an environment-friendly tempered glass deinking agent and a preparation method thereof. Background technique [0002] Glass screen printing ink is an important process in glass processing. Logos, buttons, and patterns on the edges of glass such as mobile phone touch screens and tablet computer displays are formed through screen printing and ink curing processes. The film layer formed by ink curing at high temperature has the characteristics of stable chemical properties, oxidation resistance, strong corrosion resistance, and excellent wear resistance. When the ink screen printing is bad, it needs to be reworked and re-screened or after long-term use, the ink on the glass is damaged or aged, then it is necessary to remove the ink and re-screen the screen. Due to the strong adhesion of the ink, it is a difficult problem in the current application to completely remove it in...
