Embodiment 1

[0036] The embodiment of the present invention provides a kind of preparation method of hydrophobic glass, such as figure 1 As shown, the method includes:

[0037] In step 101, the glass to be coated is cleaned with a dispersion liquid to obtain the cleaned glass to be coated.

[0038] In step 102, a silica sol is prepared, and polyethylene glycol with a volume within a preset first numerical range and a molecular weight within a preset second numerical range and a volume within a preset third numerical range are added to the silica sol. Low surface energy substances within the numerical range generate silica / polyethylene glycol mixed sols.

[0039] In step 103, the cleaned glass to be coated is immersed in the silicon dioxide / polyethylene glycol mixed sol, and the glass to be coated is coated by a pulling method to obtain a coated glass.

[0040] The preparation method of the hydrophobic glass in the embodiment of the present invention, the method comprises: cleaning the gl...

Embodiment 2

[0042] The embodiment of the present invention provides a method for preparing hydrophobic glass, the process of the method comprising:

[0043] In step 201, the glass to be coated is cleaned with a dispersion liquid to obtain the cleaned glass to be coated.

[0044] Wherein, the above-mentioned dispersion liquid is a solution formed by mixing and stirring the polishing powder and distilled water.

[0045] In practice, the glass to be coated is immersed in the dispersion so that all surfaces of the glass to be coated are covered with the dispersion. Wipe it off, and rinse the glass to be coated with distilled water to obtain the cleaned glass to be coated.

[0046] Optionally, due to the various material components used in preparing the dispersion and the methods of cleaning the glass to be coated, one of the specific implementation methods is provided below:

[0047] In step 1, cerium oxide polishing powder and distilled water are used to mix and stir evenly to obtain a dis...

Abstract

The invention discloses a method for preparing hydrophobic glass, which belongs to the field of automobile manufacturing. The method includes cleaning the glass to be coated with a dispersion liquid, obtaining the cleaned glass to be coated, and preparing a silica sol, adding a volume within a preset first numerical range and a molecular weight within a preset first value range to the silica sol. The polyethylene glycol in the two numerical ranges and the low surface energy substance whose volume is in the preset third numerical range generate a silicon dioxide / polyethylene glycol mixed sol, and immerse the cleaned glass to be coated in the carbon dioxide In the silicon / polyethylene glycol mixed sol, the glass to be coated is coated by a pulling method to obtain a coated glass. By adopting the present disclosure, the light transmittance of the coated glass can be improved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a method for preparing hydrophobic glass. Background technique [0002] With the development of the economy and the improvement of people's living standards, cars have gradually entered people's lives and improved people's quality of life. Especially in rainy days, traveling by car saves people from the distress of being drenched in rain. However, when it rains, water droplets stick to the glass of the car and are not easy to flow, which will affect the driver's line of sight and cause traffic accidents. [0003] In order to solve the problem of water droplets adhering to the glass, automobile manufacturers use the method of coating on the automobile glass to make the coated automobile glass have a hydrophobic film. The adhesion between the glass and the car can make water droplets slide off the car glass quickly under the action of its own gravity. Related coating tech...
