Problems solved by technology

[0002] Usually, PVC film is attached to the glass surface used in the fields of intelligent interactive flat panel, conference machine, advertising machine, etc., but the PVC film will appear aging, yellowing, cracking and other phenomena when it is exposed to sunlight or air for a long time
Moreover, due to the temperature difference between the inner and outer surfaces of the glass during use, water mist often appears on the inner surface of the glass.

preparation example Construction

[0026] A preparation method of anti-fog glass, comprising the following steps:

[0027] 1. Pre-processing.

[0028] Take clean glass, use one side of the glass as the treatment surface, and polish the treatment surface; then clean the treatment surface to remove ions on the surface.

[0029] It can be understood that conventional methods can be used to polish and ion-clean the glass. However, mixing polishing powder with water to make a polishing liquid with a concentration of 5%-10% by mass, coating it on the air surface of the glass and scrubbing with a brush has a relatively good effect. Good polishing effect is conducive to the adhesion of subsequent film layers. Similarly, conventional methods can be used for ion cleaning of glass, such as rinsing with deionized water, or cleaning with an ion blower, etc. However, performing ion cleaning in the above two ways at the same time has a better effect of removing ions.

[0030] It can be understood that either the air side of...

Embodiment 1

[0049] A kind of anti-fog glass, prepared by the following method:

[0050] 1. Pre-processing.

[0051] 1. Tempering treatment: treat the glass at 600°C for 8 minutes.

[0052] 2. Polishing: Take float glass, wash it with water and then dry it to get clean and dry glass. Mix water with glass polishing powder to make a polishing liquid with a mass percentage concentration of 7.5%, and then evenly apply it on the air surface of the glass, and then clean the machine to let the brush in the machine rotate forward / reversely 3 times After brushing and flushing, the air surface is polished.

[0053] 3. Ion cleaning: Rinse the air surface of the glass with deionized water, and then clean the air surface of the glass with an ion blower to remove the ions on the surface.

[0054] 2. Spray coating.

[0055] 1. Preheating: Preheat the pretreated glass at 30°C to make the glass reach room temperature.

[0056] 2. Spraying: Use automatic spraying equipment (commercially available) to s...

Embodiment 2

[0064] A kind of anti-fog glass, prepared by the following method:

[0065] 1. Pre-processing.

[0066] 1. Tempering treatment: Treat the glass at 580°C for 10 minutes.

[0067] 2. Polishing: Take float glass, wash it with water and then dry it to get clean and dry glass. Mix water with glass polishing powder to make a polishing liquid with a concentration of 5% by mass, and then evenly apply it on the air surface of the glass, and then clean the machine to let the brush in the machine rotate forward / reversely for 3 times After brushing and flushing, the air surface is polished.

[0068] 3. Ion cleaning: Rinse the air surface of the glass with deionized water, and then clean the air surface of the glass with an ion blower to remove the ions on the surface.

[0069] 2. Spray coating.

[0070] 1. Preheating: Preheat the pretreated glass at 27°C to make the glass reach normal temperature.

[0071] 2. Spraying: Use automatic spraying equipment (commercially available) to spra...

Abstract

The invention relates to anti-fog glass and a preparation method thereof, and belongs to the technical field of glass coating. The method comprises the following steps: pretreatment: taking clean glass, using one surface of the glass as a treatment surface, and polishing the treatment surface; cleaning the treatment surface, and removing ions on the surface; film layer spraying: controlling the pressure intensity of a nozzle to be 2 Mpa-6 Mpa and the flow to be 10 g / m(2)-20 g / m(2) during spraying atomization, spraying a film layer material to the treatment surface of the glass to form an anti-fog film layer with a rough surface; and curing: leaving the glass sprayed with a film layer standstill for 20-40 minutes at normal temperature, and curing the glass for 30-40 minutes at the temperature of 80-150 DEG C to obtain the final product. The anti-fog glass prepared by the preparation method has good anti-fog effect, and can be widely used in the fields of intelligent interactive displays, meeting machines, advertising machines and the like.

Description

technical field [0001] The invention relates to the technical field of glass coating, in particular to an anti-fog glass and a preparation method thereof. Background technique [0002] Usually, PVC film is attached to the surface of glass used in product fields such as smart interactive panels, conference machines, and advertising machines. However, the PVC film will age, yellow, and crack when it is exposed to sunlight or air for a long time. Moreover, due to the temperature difference between the inner and outer surfaces of the glass during use, water mist often forms on the inner surface of the glass. Contents of the invention [0003] Based on this, it is necessary to address the above problems and provide an anti-fog glass that can improve the phenomenon of water mist formed on the glass surface. [0004] A preparation method of anti-fog glass, comprising the following steps: [0005] Pre-treatment: take clean glass, use one side of the glass as the treatment surfac...
