Abstract

The invention relates to the field of multifunctional glass preparation, and provides abrasion-resistance glass based on a micro-nano array structure coating. A plasma spraying technology is adopted for preparing a silicon nitride coating with the thickness of 100-200 nm on the surface of the abrasion-resistance glass; a zinc fluoride micro-nano array layer with the thickness of 80-150 nm grows onthe surface of the silicon nitride coating, and zinc fluoride is hollowed and grows perpendicularly on the surface of the silicon nitride coating; polymer macromolecular chains are grafted on the surface of the zinc fluoride micro-nano array and are carboxymethyl chitosan. The invention further discloses a preparation method of the abrasion-resistant glass. According to the prepared abrasion-resistance glass, a membrane layer and a glass substrate are good in bonding performance, the abrasion resistance of the glass can be improved effectively, and mechanical properties are excellent.

Description

Technical field: [0001] The invention relates to the field of multifunctional glass preparation, in particular to a wear-resistant glass based on a micro-nano array structure coating and a preparation method thereof. Background technique: [0002] Ordinary flat glass has good light transmission performance, low price, has a wide range of applications, and has made great contributions to the improvement of human living and production levels. However, in some occasions, such as high-speed rail windshields, car windows, etc., ordinary flat glass faces the disadvantages of low strength and insufficient impact resistance. For brittle materials such as glass, the flexural strength can best reflect its mechanical performance level. However, the currently commonly used silicate glass has low flexural strength, mainly due to the fact that impurities are easily introduced into the glass raw materials, and there are inhomogeneous phases and inhomogeneous stress regions inside the glas...
