Abstract

The invention provides a formulation of silicon dioxide heat-insulating grouting fireproof glass fireproof glue and a preparation method thereof. The formulation comprises, by weight, 15-25 parts of hydrophilic nano core-shell structure organic-inorganic hybrid particle, 20-30 parts of deionized water, 10-13 parts of sodium fluorosilicate, 8-12 parts of sodium metaaluminate, 7-10 parts of waterborne bentonite, 10-15 parts of carbon forming agent, 10-12 parts of ammonium polyphosphate, 7-10 parts of cross-linking agent, 6-11 parts of alkaline zinc carbonate, 8-16 parts of waterborne rosin emulsion, 14-18 parts of polysiloxane emulsion and 18-22 parts of potassium hydroxide water solution. The glue has good waterproof performance, heat resistance and heat insulativity are improved greatly, the problem of bubbles generated during curing is avoided, and the glue has excellent light transmittance.

Description

Technical field: [0001] The invention relates to a formula of silica heat-insulating grouting fireproof glass fireproof glue and a preparation method thereof. Background technique: [0002] As a new building fireproof product, fireproof glass is adopted by more and more buildings. Its main function in fireproofing is to control the spread of fire or to isolate smoke. It is a measure-type fireproof material. Its fireproof effect is Fire resistance performance was evaluated. It is a special glass that has been processed and treated by a special process and can maintain its integrity and heat insulation in the specified fire resistance test. [0003] Fire-resistant glass is divided into single-piece fire-resistant glass (DFB) and composite fire-resistant glass (FFB) according to different structures. Among them, the composite heat-insulating fire-resistant glass is composed of two or more layers of original glass sheets with one or more layers of water-soluble fire-resistant ...
