Problems solved by technology

Surfactant spraying method is the method with the most technical research and wide application. It achieves the anti-fog effect by changing the contact angle of the glass, but it is not resistant to wiping and has a short life. The volatilized solvent in the formula threatens human health; the coating method is mainly Use superhydrophilic or superhydrophobic polymer compounds and nano-scale metal oxide particles to form films on the surface of glass. There are many types, and the raw materials are easy to obtain, bu

Abstract

The invention discloses heat-insulating anti-fog glass and a preparation method thereof, and relates to the technical field of glass. The preparation method comprises the following steps: firstly, melting and curing modified silicon dioxide and auxiliaries, and then melt-blowing potassium carbonate and titanium dioxide on the surface of glass; a compact potassium hexatitanate whisker coating is formed through ultrasonic and microwave-assisted high-temperature calcination, and then a high-voltage electrostatic field is utilized to assist curing, so that potassium hexatitanate whiskers are closely crosslinked with the glass, and the heat insulation performance of the glass is improved; finally, pouring molten glass on the surfaces of the potassium hexatitanate whiskers, and performing secondary high-voltage electrostatic field curing; wherein the modified silicon dioxide is prepared into a porous microsphere shape by taking a silicon dioxide microsphere as a core material and zirconium dioxide as a wall material, so that the infrared reflection capability of the glass is improved. The heat-insulating and anti-fog glass prepared by the invention has heat-insulating and anti-fog effects.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a heat-insulating anti-fog glass and a preparation method thereof. Background technique [0002] Glass has a wide range of uses in industrial production and daily life. However, when there is a certain temperature difference between the two sides separated from each other, it is easy to generate fog on the glass surface, and the tiny dewdrops diffuse the light, thereby significantly reducing the light transmittance of the glass and bringing great inconvenience to life. [0003] At present, the common glass anti-fog technology is mainly surfactant spraying method and coating method. Surfactant spraying method is the method with the most technical research and wide application. It achieves the anti-fog effect by changing the contact angle of the glass, but it is not resistant to wiping and has a short life. The volatilized solvent in the formula threatens human health; the coating m...
