Abstract

The invention discloses a method for preparing a graphene reinforced glass material by melting and sintering. The method comprises the following steps: step 1, mixing silicon dioxide, vanadium oxide, diboron trioxide, titanium nitride, barium chloride, aluminum oxide, lignocellulose, magnesium oxide, selenium powder and graphene, grinding, and sieving to obtain mixed powder with the particle size of 100-200 meshes; step 2, the mixed powder obtained in the step 1 is subjected to heat preservation sintering for 1-2 h under the condition of 400-600 DEG C, the temperature is increased to 800-900 DEG C at the heating rate of 2-5 DEG C/min, heat preservation sintering is conducted for 45-60 min, and compression molding is conducted; step 3, naturally cooling to room temperature; and step 4, grinding and polishing the glass profile naturally cooled in the step 3 to obtain the graphene reinforced glass material. The glass material prepared by the method has enhanced impact strength, breaking strength and surface hardness, and is beneficial to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of glass materials, and in particular relates to a method for preparing graphene-reinforced glass materials by melting and sintering. Background technique [0002] At present, with the improvement of people's living standards, the requirements for lightweight products are increasing. For the glass market, glass products have penetrated all aspects of people's lives.
