Processing method of nano-coated anti-ultraviolet glass

Abstract

The invention discloses a processing method of a nano-coated anti-ultraviolet glass. The processing method comprises at least: cleaning->coating preparation->precision coating equipment->precision flash drying leveling->precision infrared curing->precision strong cooling conveying. The nano-coated anti-ultraviolet glass has obvious advantages of ultraviolet-shielding compared with the ordinary glass. The nano-coated anti-ultraviolet glass is prepared by coating a layer uniform nano material on the glass surface by using the nano-coating process, the ultraviolet-shielding ability of the nano anti-ultraviolet glass can be greatly improved, and the original visible light transmittance and color of the float glass are not significantly changed. Modified nano titanium dioxide is added in the nano-coated anti-ultraviolet glass, the nano titanium dioxide is wetted with a surfactant, the clustered nano-titanium dioxide is dispersed by using the ultrasonic wave high frequency, and a film of thesurfactant is formed on the surface of the nano titanium dioxide particles, so that the dispersivity of the nano titanium dioxide in the coating is improved, the coating powdering resistance is improved, and the visible light transmittance and ultraviolet shielding rate are increased.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to a method for processing nano-coated anti-ultraviolet glass. Background technique [0002] Glass is an integral part of the architectural field and undertakes many important functions, including beautifying buildings, lighting and bringing open views to the interior. But ordinary glass has high sunlight transmittance and low infrared reflectivity. Most of the sunlight enters the room through the glass, thereby heating objects, and the energy of these indoor objects will be lost through the glass in the form of radiation. The glass coated with low-emissivity film has a high reflection effect on the infrared energy of objects at room temperature. This feature greatly reduces the heat transfer coefficient of low-emissivity glass and effectively improves the thermal insulation and heat insulation performance of windows.

AI Technical Summary

Problems solved by technology

[0003] Ordinary glass is easily polluted in the haze environment, which affects light transmission, and cleaning glass curtain walls at high altitudes is a high-risk work, which is time-consuming and labor-intensive

Existing glass has only a simple heat insulation effect in winter and summer, and can only block heat in one direction, but cannot block ultraviolet rays and control temperature. Therefore, when people choose architectural glass, in addition to considering the appearance characteristics, they pay more attention to its heat control and ultraviolet insulation capabilities. and a comfortable balance of internal sunlight transmission and other properties
