Preparation method of ceramic coating on glass surface

Abstract

The invention relates to a preparation method of a ceramic coating on a glass surface. The preparation method comprises the following steps: preparing 40-70 parts of silicon dioxide, 50-60 parts of aglass glaze, 10-15 parts of aluminum oxide, 6-12 parts of magnesium oxide, 6-12 parts of boron oxide, 2-12 parts of calcium oxide, 6-12 parts of zinc oxide, 2-10 parts of potassium oxide, 0.7-1.2 parts of an antistatic agent, 0.4-0.9 part of an ultraviolet light absorber, 0.1-0.4 part of a dispersant and 0.2-0.6 part of an antifoaming agent; subjecting a glass bottle to polishing and alkali-washing; putting the above powder into a container, adding a proper amount of deionized water, carrying out uniform stirring, adding water glass with a ratio of 1: 10, and performing sufficient stirring for2 hours with a stirrer until uniformly dispersed slurry without agglomerates or agglomerated small particles is obtained; and carrying out thermal spraying, laser remelting treatment and a laser in-situ reaction. The ceramic coating on the glass surface has the advantages of high density and wear resistance.

Description

technical field [0001] The invention relates to the technical field of glass surface coating treatment, in particular to the preparation of a glass surface ceramic coating. Background technique [0002] As a traditional brittle material, glass has excellent transparency and refraction, high hardness, high compressive strength, and good chemical stability. Series special features. It is widely used in daily utensils, construction engineering, instrumentation, automobile, electromechanical, national defense, electronic industry and other fields. [0003] However, the disadvantages of glass materials such as low ductility and impact toughness, weak thermal shock resistance, poor processability, and frequent accidents increase the difficulty in manufacturing and processing, hindering its wide application in engineering structures. Therefore, in many occasions, glass materials usually need to form a composite structure with ceramic materials with high plasticity, high toughness...
