Abstract

The invention relates to a fireproof interlayer adhesive, which is prepared from the following raw materials in parts by weight: 45 to 50 parts of nano silicon dioxide sol, 25 to 35 parts of inorganic alkali solution, 0.8 to 1.6 parts of heat-resistant dispersant, 0.1 to 0.6 part of stabilizer, 0.2 to 0.8 part of flame retardant, 0.1 to 0.6 part of defoaming agent and 5 to 15 parts of anti-condensing agent. Wherein the stabilizer is beta-cyclodextrin; the heat-resistant dispersant is glycerol; the inorganic alkali solution is a mixed solution of potassium hydroxide and sodium hydroxide, and the molar ratio of potassium hydroxide to sodium hydroxide is (1.5-4): 1. According to the fireproof interlayer glue prepared by the preparation method disclosed by the invention, the dispersion uniformity and stability of the silica sol dispersion liquid can be effectively improved while high light transmittance of the fireproof interlayer glue is ensured, so that the fire resistance of fireproof glass is effectively improved, and the product application space is huge.

Description

technical field [0001] The invention relates to the technical field of compound synthesis, in particular to a fireproof interlayer adhesive, a preparation method thereof and fireproof glass containing the same. Background technique [0002] At present, inorganic grouting fireproof glass is a kind of composite fireproof glass. Because of its good fireproof and heat insulation performance and low cost, it has a wide range of applications. Inorganic grouting fireproof glass has gradually become an important development direction of building fireproof glass. The more scientific research institutions and the market pay attention. At present, the fireproof interlayer glue in the inorganic grouting fireproof glass on the market is mainly silicate-based inorganic materials. The grouting method is often used to pour the fireproof interlayer glue into the cavity of the multilayer fireproof glass sealed with flame retardant strips. The glue is cured into a transparent silicate colloid...
