Preparation method of high-transmittance and high-strength antibacterial glass

Abstract

The invention relates to a preparation method of high-transmittance and high-strength antibacterial glass. The method comprises the following steps: forming a salt solution, wherein the mass ratio ofpotassium nitrate in the salt solution is 40%-80%, the mass ratio of potassium nitrite is 10%-20%, the mass ratio of sodium nitrate is 15%-20%, the mass ratio of sodium nitrite is 5%-10%, the mass ratio of silver nitrate is 0.005%-0.08%, the mass ratio of aluminum oxide is 1%-7%, the mass ratio of potassium hydroxide is 1%-3%, the mass ratio of silicon oxide is 1%-5%, and the mass ratio of other substances is 0.15%-1.5%; immersing glass to be reinforced into the salt solution to chemically reinforce the glass; and taking out the chemically reinforced glass, and gradually cooling the chemicallyreinforced glass to room temperature. According to the method, the proportions of KNO3, KNO2, NaNO3, NaNO2 and AgNO3 in the salt solution are reprepared, so that K<+>, Na<+> and Ag<+> can be fully exchanged with alkali metals Na<+> and Li<+> in the glass, and the antibacterial and high-strength properties of the glass are guaranteed.

Description

technical field [0001] The present application relates to a method for preparing glass, in particular to a method for preparing high-transparency, high-strength antibacterial glass. Background technique [0002] Glass is a kind of amorphous inorganic non-metallic material, which is generally prepared from a variety of organic minerals as the main raw material and a small amount of auxiliary raw materials. With the development of industrialization and scale of glass, glasses with various uses and performances have come out one after another. Glass has the characteristics of high light transmission, high temperature resistance, and chemical corrosion resistance. Heating, strength, scratch resistance, antibacterial and other properties are integrated on the glass. Today, glass has become an important material in daily life, production and science, and is widely used in construction, daily use, art, medical treatment, chemistry, electronic components, instruments, automobiles, ...
