The invention relates to a transparent fireproof
adhesive, a preparation method thereof and a composite fireproof glass containing the transparent fireproof
adhesive. The transparent fireproof
adhesive is prepared from the following raw materials: 45-55 parts of nano-silica
sol, 25-40 parts of a water glass solution, 0.5-1.0 part of a
charring agent, 0.1-0.3 part of a
charring aid, 0.3-0.8 part of a heat-resistant stabilizer, 0-5 parts of an organic anti-condensation agent, 10-15 parts of an inorganic anti-condensation agent, 0.05-0.1 part of an
ion fixing agent, 0.3-0.5 part of a storage stabilizer, 0.1-0.5 part of a defoaming agent and 0.15-0.3 part of a crosslinking agent; wherein the
moisture content of the transparent fireproof adhesive is 30-50%. The
water content of the transparent fireproof adhesive is as low as 30-50%, the
fire resistance of the composite fireproof glass is effectively improved, and meanwhile, certain flowing performance is ensured, so that pouring is facilitated. Heat insulation type composite fireproof glass and non-heat-insulation type composite fireproof glass prepared from the transparent fireproof adhesive have the characteristics of good appearance quality, good
weather resistance, high visible light
transmittance, excellent cold flow resistance and the like.
