Embodiment 1

[0044] Embodiment 1: preparation surface ZrO is plated 2 Wear-resistant film chemically tempered flat soda lime glass

[0045] Zirconium oxychloride, deionized water, ethanol, and hydrogen peroxide are used as raw materials, wherein the volume ratio of deionized water to ethanol is 1:4, and zirconium oxychloride is 2% of the total mass of deionized water+ethanol based on the mass of zirconia, The molar ratio of hydrogen peroxide to zirconium oxychloride is 4:1. At room temperature, each substance was added sequentially for about 4 hours with thorough stirring, and a colorless transparent sol was formed. After aging for 6 hours, the viscosity of the sol reaches the coating requirement, and the viscosity of the sol is stabilized by dripping 0.5% dilute nitric acid in an amount of 0.5ml per 100ml of sol. After the sol was coated on the cleaned flat glass surface by the pulling method, the product was dried in an oven at 60°C for 30 minutes, then placed in a muffle furnace at 55...

Abstract

The invention discloses a preparation method of a chemical toughened glass product with a wearing-resisting film. The preparation method comprises the following steps of: (1), plating an oxide film on the surface of the clean glass product so as to obtain the glass product with a wearing-resisting coating; and (2), putting the glass product (obtained in the first step) with the wearing-resisting coating into molten salt, carrying out ion exchange to be strengthened for 8-18 hours at 400-500 DEG C, and subsequently cooling to the room temperature and washing so as to obtain the chemical toughened glass product. According to the method, the particularly prepared molten salt is adopted for ion exchange and tempering, the wearing-resisting coating with high hardness is combined with the surface of the glass product more tightly, and a part of surface crack can also be healed, so that the surface hardness and the anti-bending strength of the product are improved, and the application field of the chemical toughened glass product is expanded.

Description

technical field [0001] The invention belongs to the technical field of glass surface treatment, and in particular relates to a preparation method of a chemically tempered glass product with a wear-resistant film. Background technique [0002] The actual use strength of ordinary glass is very low, and it will be cracked or broken when it is slightly bumped and impacted. For brittle materials such as glass, the flexural strength can best reflect its mechanical performance level. The test results show that the average bending strength of ordinary silicate glass is lower than 100Mpa. However, the theoretical flexural strength is at least several orders of magnitude higher, based on calculations based on the strength of the chemical bonds of the glass. The current study believes that this is mainly caused by the surface damage during the production, transportation and storage of glass products and the large number of Griffith microcracks on the surface. [0003] Chemically tem...
