preparation example Construction

[0043] A method for preparing smooth glass, comprising the steps of:

[0044] 1. Pre-processing.

[0045] Take the glass substrate and polish it; then clean the glass substrate to remove the ions on its surface.

[0046]It can be understood that conventional methods can be used to polish and ion-clean the glass substrate. However, the polishing powder is mixed with water to make a polishing solution with a concentration of 5%-10% by mass, and it is coated on the surface of the glass substrate and scrubbed with a brush. It has a good polishing effect, which is conducive to the subsequent ink layer adhesion. 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.

[0047] Similarly, a smooth film layer can be prepared on the air side of the glass substrate (that is, the side of th...

Embodiment 1

[0059] A smooth glass prepared by the following method:

[0060] 1. Pre-processing.

[0061] 1. Polishing: Take float glass, wash it with water and then dry it to get clean and dry glass. Mix glass polishing powder with water to make a polishing liquid with a concentration of 7.5% 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 flushing, the air surface is polished.

[0062] 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.

[0063] 2. Spray anti-reflection coating.

[0064] When controlling the spray atomization, the pressure of the nozzle is 4.5Mpa, and the flow rate is 15g / m 2 , spraying the anti-reflection film layer material on the surface of the glass substrate to form a rough anti-reflection film layer.

Embodiment 2

[0078] A smooth glass prepared by the following method:

[0079] 1. Pre-processing.

[0080] 1. Polishing: Take float glass, wash it with water and then dry it to get clean and dry glass. Use glass polishing powder mixed with water to make a polishing liquid with a concentration of 5% by mass, and then apply it evenly 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 flushing, the air surface is polished.

[0081] 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.

[0082] 2. Spray anti-reflection coating.

[0083] When controlling spray atomization, the pressure of the nozzle is 6Mpa, and the flow rate is 20g / m 2 , spraying the anti-reflection film layer material on the surface of the glass substrate to form a rough anti-reflection film layer.

Abstract

The invention relates to smooth glass and a preparation method thereof, belonging to the technical field of glass coating. The preparation method comprises the following steps of pretreating: taking a glass substrate and polishing the glass substrate; cleaning the glass substrate, and removing ions on the surface of the glass substrate; spraying a smooth film layer: controlling the pressure intensity of a spray nozzle during spraying and atomizing to be 3MPa-7MPa, and the flow to be 15g / m<2> to 30g / m<2>, spraying the smooth film layer material on the surface of the pretreated glass substrate to obtain the smooth film layer; curing the smooth film layer: curing the glass with the smooth film layer at 40 to 650DEG C for 10 to 30 minutes to obtain a final product. According to the method, fog drops of the spraying material are controlled within a specified range by adopting a mode of controlling a spraying haze value, so that the generated fog drops are greater than those generated by conventional coating, but other adverse influences are avoided, so that a friction coefficient of the film layer surface is reduced, and the smoothness of the obtained film layer is improved.

Description

technical field [0001] The invention relates to the technical field of glass coating, in particular to a smooth glass and a preparation method thereof. Background technique [0002] Usually, the touch screen glass of products such as electronic whiteboards, smart interactive tablets, conference machines, and advertising machines needs to have a smooth surface to reduce frictional resistance, make writing smoother, or improve the touch feel. [0003] At present, the conventional method is to improve the smoothness of the glass by coating the glass surface. However, the existing coated glass still has the problems of rough hand feeling and high frictional resistance, and needs to be improved. Moreover, the plated film layer may also have the problem of falling off after long-term friction. Contents of the invention [0004] Based on this, it is necessary to address the above problems and provide a smooth glass and a preparation method thereof. The smooth glass prepared by ...
