Mobile phone touch screen polarizer cleaning agent and preparation method and application thereof

Abstract

The invention discloses a mobile phone touch screen polarizer cleaning agent and a preparation method and application thereof. The mobile phone touch screen polarizer cleaning agent is prepared by, by mass percentage, 4-6% of diethylene glycol monobutyl ether, 4-6% of ethylene glycol monophenyl ether, 1-5% of ethanol, 3-5% of ethylene glycol, 1-5% of dimethyl benzene, 3-5% of isopropanol, 8-12% of tetrahydrofurfuryl alcohol, 5-10% of triethanolamine, 10-15% of potassium hydroxide and 31-61% of tap water. During use, the mobile phone touch screen polarizer cleaning agent is boiled and used for cleaning a polarizer. The mobile phone touch screen polarizer cleaning agent has the advantages that the prepared cleaning agent is a water-soluble cleaning agent and is high in safety performance, good in cleaning ability, good in dissolving performance on colloid and resin residues, capable of increase cleaning efficiency, capable of satisfying cleanliness requirements, low in use amount, long in service life, less prone to volatilization, capable of effectively lowering cleaning cost and evident in practical value.

Description

technical field [0001] The invention relates to the field of cleaning agents for electronic products, in particular to a cleaning agent for mobile phone touch screen polarizers and its preparation and application. Background technique [0002] The rapid development of the smartphone industry has also promoted the development of the mobile phone accessories market. Consumers have higher and higher requirements for the size and workmanship of mobile phone screens. However, due to the characteristics of the LCD screen, the screen cannot be completely aligned during assembly, and even a small gap will cause light overflow on the edge of the screen. In order to solve this problem, a polarizer will be pasted around the screen. But the qualified rate of pasting polarizers is less than one-third, and most of the screens are unqualified. If these unqualified polarizer screens are used to produce mobile phones, the service life of the mobile phone will be reduced. In order to avoid...

However, due to the characteristics of the LCD screen, the screen cannot be completely aligned during assembly. Even a small gap will cause light overflow on the edge of the screen. In order to solve this problem, a polarizer will be pasted around the screen.

But the passing rate of pasting polarizers is less than one-third, and most of the screens are unqualified

At present, n-hexane, n-heptane and other solvents are generally used in the industry for cleaning, but because they are non-polar substances, there are cases where the cleaning is not clean, and these solvents have a low flash point, are easy to volatilize, and consume a lot. A lot of investment in cleaning, but little effect
