Problems solved by technology

In this way, there is a big problem: since the glass surface is hydrophilic, water will promote dirt deposition and easily produce water spots, which will largely offset the self-cleaning effect brought by the anti-static film layer
One solution is to add an additional hydrophobic film layer on the glass surface, which not only has complicated process and high cost, but also the newly added film layer will significantly reduce the antistatic property and light transmittance of the glass as a whole, which is not worth the candle.

Embodiment 1

[0026] (1) Preparation of anti-reflection sol: Mix 86.5mL of absolute ethanol, 10.2mL of tetraethyl orthosilicate, and 3.3mL of deionized water, adjust the pH of the mixture to 4 with dilute hydrochloric acid, then add 0.1mL of formamide, and The resulting mixture was heated to 40° C. and kept under magnetic stirring for 4 h, and finally cooled down to room temperature and left to age for 24 h for later use.

[0027] (2) Preparation of antistatic hydrophobic sol: Mix 86.5mL of absolute ethanol, 10.2mL of tetraethyl orthosilicate, and 3.3mL of deionized water, adjust the pH of the solution to 4 with dilute hydrochloric acid, heat the resulting mixture to 40°C and Keep warm and magnetically stir for 4 hours, and finally cool down to room temperature and let stand for 24 hours to obtain silica sol. Add 25.9mL conductive agent dropwise to the silica sol, and the dropping process lasts about 1h. After the conductive agent was added dropwise, 3 mL of hexamethyldisilazane was added ...

Embodiment 2

[0032] This embodiment is basically the same as Example 1, except that the amount of hexamethyldisilazane in step (2) is 4mL, and the glass used in step (c) is ordinary building glass, which is antistatic and hydrophobic After the film is formed, it is also necessary to soak the glass in a 15% (mass fraction) HMDS ethanol solution for 24 hours.

[0033] The double-coated glass and blank glass that embodiment 2 is made have carried out contact angle test respectively, and the result is as follows image 3 shown. image 3 It shows that the surface of the blank glass is hydrophilic, and the contact angle of the glass after coating the double-layer film increases (by 94.3°), indicating that the double-layer film does endow the glass with better hydrophobicity. The friction resistance test was carried out on the glass at room temperature, and the film on the surface was repeatedly wiped with alcohol. After 1000 times of wiping, the average transmittance of the film under light wit...

Embodiment 3

[0035] This example is basically the same as Example 1, except that the amount of conductive agent in step (2) is 30.2mL, the amount of hexamethyldisilazane is 3.3mL, and the glass used in step (c) Glass for outdoor LED display. The test results show that the double-coated glass has the same or similar antistatic, hydrophobic, and high transmittance properties as those of Examples 1 and 2.

Abstract

The invention relates to glass with antistatic, hydrophobic and anti-reflection functions and a preparation method of the glass. The preparation method comprises the steps of firstly, respectively preparing anti-reflection sol and anti-static hydrophobic sol by adopting a sol-gel method, and then plating a certain layer and number of anti-reflection films and anti-static hydrophobic films on the surface of the glass by using a lifting coating method. In the process, the thickness of the films, the dosage of a modifier and a heat treatment system are controlled, performance indexes such as therefractive index, the transmittance and the reflectivity of the films can be regulated and controlled, and the prepared glass has multiple functions of static electricity prevention, hydrophobizationand anti-reflection, is particularly suitable for being used as a solar cell cover plate without cleaning and maintenance and is applied to arid and dusty areas.

Description

technical field [0001] The invention relates to the technical field of glass materials, in particular to a glass with multiple functions such as antistatic, hydrophobic, and antireflection, and a preparation method thereof. Background technique [0002] In recent years, the photovoltaic industry has developed more and more rapidly. Under the background of the shortage of fossil energy, it is particularly important to make full use of solar energy resources. The power generation efficiency of solar cells mainly depends on the light energy conversion rate of monocrystalline silicon, which is determined by the performance of photovoltaic chips. However, it is difficult to achieve greater breakthroughs in the performance of photovoltaic chips at present. That is to say, the conversion rate of monocrystalline silicon to light energy is close to the limit, and if we want to further improve the power generation efficiency of solar cells, we can only find another way. [0003] As o...
