Abstract

A preparation method for fireproof glue for fireproof glass, comprising the following steps: 1. Adding hydrophilic nano core-shell structure organic-inorganic hybrid particles into deionized water, stirring at a high speed for 20-30min, with a stirring speed of 1500- 1800r/min to obtain solution one; two, add sodium fluorosilicate, sodium metaaluminate, water-based bentonite, polyphosphate, ammonium polyphosphate, sodium borate, basic zinc carbonate, water-based rosin emulsion and poly Silicone emulsion, heated at 100-120°C and stirred for 40-60min to obtain solution 2; 3. Place solution 2 in a vacuum environment for vacuum pressurization at a pressure of 10-20MPa and pressurize for 20-30min to obtain Crude fireproof glue; 4. Add potassium hydroxide aqueous solution with a mass percent concentration of 50% to the crude fireproof glue, and slowly stir for 20-30min under vacuum conditions to obtain the finished product. The fireproof glue prepared by the invention can make the glass have the advantages of no microbubble, high transmittance and long fireproof time.

Description

technical field [0001] The invention belongs to the technical field of glass fireproof production, and in particular relates to a preparation method of fireproof glue for fireproof glass. Background technique [0002] As the pace of urbanization is getting faster and faster, the building windows of houses are getting bigger and bigger. Elegant, beautiful and functionally safe glass components are gradually being favored by domestic and foreign designers, which directly leads to various types of safety glass. And special glass is developing rapidly in the architectural glass industry. Architectural glass has gradually developed from simply being used as a lighting and decorative material to a composite of multiple functions such as light control, room temperature adjustment, noise reduction, and improvement of the living environment. Among them, insulating glass is a new type of building material with good heat insulation, sound insulation, aesthetics and applicability, and ...
