Embodiment 1

[0025] The preparation method of the self-cleaning high light transmittance tempered glass of this embodiment includes the following steps:

[0026] (1) Clean the glass with a strong acid with a mass ratio of concentrated sulfuric acid and concentrated nitric acid of 1:3. After cleaning, wash it with deionized water for 3 times, and dry it in an oven at 80°C;

[0027] (2) Then the dried glass is treated with plasma. The plasma treatment method is to treat the toughened glass with a corona machine. The working frequency of the corona machine is 8KHZ, the output voltage is 50000V, and the electrode treatment width is 100mm.

[0028] (3) Mix 3 parts by mass of anatase titanium dioxide, 10 parts by mass of silicon dioxide precursor tetraethyl orthosilicate, 1 part by mass of silane coupling agent KH-550, 1 part by mass of dispersant SN5040, and 70 parts by mass Parts by mass of deionized water were mixed and put into a sand mill, and dispersed at a speed of 3000 r / min for 6 hours ...

Abstract

The invention discloses a preparation method of self-cleaning high-transmittance tempered glass. The preparation method comprises the following steps: (1) cleaning a piece of glass; (2) performing plasma treatment on the glass; (3) preparing a self-cleaning water-based coating by mixing a silica precursor, a silane coupling agent, metatitanic acid, silicon dioxide, hydrofluoric acid to react, andthen adding ammonia water to adjust the pH, wherein the obtained nano-dispersion liquid is super hydrophilic, anti-fogging and photocatalytic (decomposition of organic matters), and has the function of releasing negative oxygen ions and the like, that is, a self-cleaning function. (4) Roller coating of the glass; (5) Drying. The self-cleaning high-transmittance tempered glass prepared with the method is relatively low in water drop contact angle (less than 10 degrees), relatively high in transmittance (the enhanced transmittance is greater than 2%, 400 nm to 1100 nm), and excellent in self-cleaning performance.

Description

technical field [0001] The invention relates to the technical field of self-cleaning toughened glass for buildings, in particular to a method for preparing self-cleaning high-transmittance toughened glass for buildings. Background technique [0002] With the rapid development of my country's construction industry, the application of glass curtain walls is becoming more and more extensive. Glass curtain wall can not only play a good decorative role in buildings, but also achieve various purposes such as lighting, wind protection, sound insulation, heat insulation, and energy saving, so it has a good market development prospect in the construction industry. The cleaning technology of glass curtain wall is demanding and difficult, and it is easy to pollute the surrounding environment after using a large amount of organic solvents and acidic detergents for cleaning, and the discharge of cleaning waste liquid is also a problem. In addition, if it is cleaned frequently, it will b...
