Problems solved by technology

However, the coating layer on the glass surface in the conventional technology is often damaged due to repeated friction during use.
For example, the flat panel used for writing display, due to long-term writing with a pen, will cause the film to wear out and reflect light

preparation example Construction

[0028] A preparation method of coated glass, comprising the following steps:

[0029] 1. Pre-processing.

[0030] Take the clean glass and polish the air surface; then clean the air surface of the glass to remove the ions on the surface.

[0031] 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.

[0032] 2. Spray coating.

[0033] When controlling spraying and atomization, the pressure of the noz...

Embodiment 1

[0039] A kind of coated glass is prepared by the following method:

[0040] 1. Pre-processing.

[0041] 1. 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 solution with a concentration of 7.5% by mass, and then apply it evenly on the glass surface, and then clean the machine and let the brush in the machine rotate forward / reversely for 3 times. Then flush and polish the air surface.

[0042] 2. 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.

[0043] 2. Spray coating.

[0044] Carry out film layer spraying with automatic spraying equipment (commercially available), the pressure of nozzle is 4Mpa when controlling spraying atomization, and flow rate is 15g / m 2 , Spray the film layer material on the air surface of the glass to form a rough film layer.

Embodiment 2

[0051] A kind of coated glass, its preparation method is basically the same as the coated glass of embodiment 1, the difference is: in the step of spraying the film layer, the pressure of the nozzle is 6Mpa when the spraying atomization is controlled, and the flow rate is 20g / m 2 .

Abstract

The invention relates to film-plated glass and a preparation method thereof, and belongs to the technical field of the film plating of glass. The preparation method comprises the following steps of pre-processing: taking clean glass, and polishing the air surfaces of the glass; afterwards, cleaning the air surfaces of the glass, so as to remove ions carried on the surfaces of the glass; the spray-coating of film layers: controlling a spray nozzle to be under pressure intensity of 2Mpa to 6Mpa and at a flow of 10g / m2 to 20g / m2 during spray-coating atomization, and spray-coating a film layer material on the air surfaces of the glass, so as to form film layers of which the surfaces are rough; curing: first curing the glass spray-coated with the film layers for 2min to 10min at 30 DEG C to 70 DEG C, and then tempering the glass for 18min to 25min at 550 DEG C to 700 DEG C, so as to obtain the film-plated glass. According to the film-plated glass obtained and prepared by the above method, the film layer material and the glass can be completely fused; the effect of combining two into one is achieved; the wear resistance of the film-plated glass is increased. Further, through controlling the roughness of the film layers, the surfaces of the obtained glass are little in reflection; the light reflection of the glass is reduced. The film-plated glass can be widely applied to the fields of products of intelligent interaction tablet computers, conference machines, advertising machines and the like.

Description

technical field [0001] The invention relates to the technical field of glass coating, in particular to a coated glass and a preparation method thereof. Background technique [0002] Usually, the surface of glass used in product fields such as smart interactive panels, conference machines, and advertising machines is coated with a film to reduce the reflection of the glass surface. However, the coating layer on the glass surface in the conventional technology is often damaged due to repeated friction during use. For example, the flat panel used for writing display, due to long-term writing with a pen, the film layer will wear out and reflect light. Contents of the invention [0003] Based on this, it is necessary to provide a glass coating method for the above problems. The film layer obtained by this method can not only reduce the glass reflection caused by strong light, but also has the advantage of good wear resistance, and it is not easy to produce The phenomenon of r...
