Preparation method of high-strength compound glass

Abstract

The invention provides a preparation method of a high-strength compound glass, and relates to the technical field of glass making. The preparation method comprises the following steps: (1) preparing aglass powder; (2) adding nanometer ZrO2 into an ethanol aqueous solution, adding a silane coupling agent, ultrasonically dispersing for 1 hour, adding citric acid dropwise to regulate the PH to 3-5,raising the temperature to 40-50 DEG C, stirring and reacting for 2-4 hours, implementing suction filtration, drying a filter cake in vacuum to obtain the modified silane coupling agent; (3) adding BPO (benzoyl peroxide), the modified silane coupling agent and methyl methacrylate into distilled water, raising the temperature to 50-60 DEG C, having a polymerization reaction while stirring, reactingfor 5-20 minutes, then adding dopamine, zinc stearate and the glass powder, raising the temperature to 70-85 DEG C, continuing to stir and have the polymerization reaction for 30-50 minutes, then reducing the temperature, cooling to the room temperature, degassing in vacuum for 30-50 minutes; (4) pouring degassed thick liquid into a mould to implement hot press molding, and obtaining the compoundglass. The prepared compound glass is high in strength, good in decorativeness, and extensive in use.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a method for preparing high-strength composite glass. Background technique [0002] Human beings have learned to make and use glass for thousands of years, but for more than 1,000 years, the development of glass as a building material is relatively slow. With the development of modern science and technology and glass technology and the improvement of people's living standards, the function of glass is no longer just to meet the lighting requirements, but to have the ability to adjust light, heat insulation, safety (bulletproof, anti-theft, fire prevention, radiation protection) , anti-electromagnetic interference), artistic decoration and other characteristics. With the continuous development of demand, glass molding and processing methods have made great progress and development. At present, many new technology glasses such as interlayer, tempering, ion exchange, g...

AI Technical Summary

Problems solved by technology

At present, many new technology glasses such as interlayer, tempering, ion exchange, glaze decoration, chemical thermal decomposition and cathode sputtering have been developed, so that the amount of glass used in buildings has increased rapidly, becoming the third largest after cement and steel. Building materials, although the existing tempered glass, wired glass or laminated glass has good safety, but the production process is complicated and the decoration is not high. The invention provides a preparation method of high-strength composite glass suitable for architectural decoration
