Problems solved by technology

The cleaning agent currently used is a strong alkaline cleaning agent, but since the aluminum metal in the molybdenum-aluminum-molybdenum coated glass coating is easily corroded in an alkaline cleaning agent with a pH greater than 10, it is necessary to provide a moderately alkaline cleaning agent with good cleaning effect. cleaning agent

Embodiment 1

[0047] First take 20g of monoethanolamine and pour it into a round-bottomed flask. After the distillation device is assembled, nitrogen is introduced to protect the monoethanolamine; The molar ratio of monoethanolamine is 1:4. Take 292g of ethylenediaminetetraacetic acid and 232g of monoethanolamine and slowly add them into the round bottom flask containing monoethanolamine for stirring reaction. The stirring speed is controlled at 200r / min, and the stirring time is 2h;

[0048] Turn on the vacuum pump and use the receiving bottle to receive the condensed and recovered water;

[0049]During the reaction period, the acidity of the reaction solution of EDTA and monoethanolamine was detected every 30 minutes: 1 gram of the reaction solution was prepared as a deionized aqueous solution with a mass concentration of 1%, and titrated with 0.1 mol / L standard acid. When the volume of standard acid consumed does not increase (maintains a certain value), it indicates that the acid value ...

Embodiment 2

[0053] The preparation method of this example is exactly the same as that of Example 1, except that the reaction temperature is 110° C. and the stirring time is 3 hours.

Embodiment 3

[0055] The preparation method of Example 3 is exactly the same as that of Preparation Example 1, except that the reaction temperature is 130° C. and the stirring time is 2.5 h.

Abstract

The invention relates to the field of glass cleaning agents, and discloses a pH stabilizer, a preparation method of the pH stabilizer, a cleaning agent for molybdenum-aluminum-molybdenum coated glass and a preparation method of the cleaning agent. The pH stabilizer is ethylenediaminetetraacetic acid amide. The preparation method of the pH stabilizer comprises the steps of mixing ethylenediaminetetraacetic acid and monoethanolamine according to a molar ratio of 1: 4, and reacting at a constant temperature under the protection of nitrogen to prepare ethylenediaminetetraacetic acid amide. The cleaning agent for molybdenum-aluminum-molybdenum coated glass comprises the following components in percentage by weight: 1-3% of a corrosion inhibitor, 5-15% of a cosolvent, 10-20% of an organic solvent, 10-20% of a pH stabilizer, and 42-74% of deionized water. The pH stabilizer disclosed by the invention can be used for preparing a cleaning agent for molybdenum-aluminum-molybdenum coated glass; and the cleaning agent for the molybdenum-aluminum-molybdenum coated glass has the advantages of being moderate in alkalinity, free of corrosion on the coated glass, easy to wet, free of metal ions, low in foam, easy to rinse, suitable for spraying and ultrasonic cleaning and the like.

Description

technical field [0001] The application relates to the field of cleaning agents, more specifically, it relates to a pH stabilizer, a preparation method thereof, a cleaning agent for molybdenum-aluminum-molybdenum coated glass and a preparation method thereof. Background technique [0002] Molybdenum aluminum molybdenum ITO (Indium Tin Oxide, indium tin oxide) coated glass is coated with ITO conductive film on the front and back surfaces of the glass by magnetron sputtering in a vacuum state, and then coated with molybdenum, aluminum, Molybdenum metal coating. Molybdenum-aluminum-molybdenum metal film is currently widely used in capacitive touch screen module materials, mainly as ITO line wires. It has low resistance, low expansion coefficient, and strong oxidation resistance, which can effectively improve the stability, response speed and weather resistance of capacitive screens. Molybdenum aluminum molybdenum ITO coated glass is mainly used in the touch screen of electronic...
