Problems solved by technology

In addition, these outdoor LCD screens will also generate a larger amount of static electricity because of their higher power. The generation of static charges will absorb more dust and bacteria in the air, making the display screen a place where bacteria breed seriously, and the outdoor environment will cause Different degrees of bacterial transmission
The existing cleaning agents are either a mixture of pure water and detergent, or are aimed at ordinary dirt such as mobile phones and computers. There is no antistatic, antibacterial and effective cleaning agent suitable for outdoor LCD screens.

Abstract

The invention discloses a preparing method of a cleaning agent for an outdoor liquid crystal display screen. The cleaning agent is prepared from, by weight, 15-30 parts of surfactant, 5-15 parts of bactericide, 2-8 parts of antioxidant, 1-5 parts of antistatic agent, 0.5-2 parts of auxiliary, 2-8 parts of ethyl alcohol and 20-40 parts of deionized water. The preparing method includes the steps that the raw materials are sequentially added into deionized water and mixed through stirring. The prepared cleaning agent can effectively remove dust and inhibit bacteria, improves the outdoor liquid crystal display screen in the aspects of removing static electricity and reducing mosquito retention and has high popularization value.

Description

technical field [0001] The invention relates to the field of cleaning agent preparation, in particular to a method for preparing a cleaning agent which is more effective in removing static electricity and resisting mosquitoes and is used on an outdoor liquid crystal screen. Background technique [0002] LCD screen is a screen with liquid crystal material as the basic component, which is widely used, including electronic equipment for personal use such as our mobile phones and computers, as well as outdoor large-scale display equipment such as stadiums and shopping malls. There are roughly two types of stains on LCD panels, one is the dust in the air that has accumulated over time, the other is fingerprints and oil stains left by users inadvertently, and for outdoor LCD screens, stains Its main components are complex, including dust, rain marks, fibers, mosquitoes and bird droppings, etc., which are different from ordinary stains. In addition, these outdoor LCD screens will ...
