Example Embodiment
[0076] An embodiment of the present invention also proposes a method for preparing a transparent fireproof adhesive, which specifically includes the following steps:
[0077]Add carbon-forming agent, carbon-forming aid, heat-resistant stabilizer, inorganic anti-condensation agent, ion fixative, storage stabilizer, defoamer and cross-linking agent to the nano-silica sol in sequence, and stir while adding. After uniform, the first solution is obtained;
[0078] The water glass solution is added to the first solution, or the first solution is added to the potassium water glass solution, transferred to a vacuum stirring vessel, the temperature of the system is controlled within 60°C, preferably 20-60°C, and stirred for 30-60min, Then degas for 30-40min under a vacuum lower than -0.096MPa, after decompression, filter the solution with a 150-200 mesh screen to obtain a transparent fireproof glue;
[0079] Wherein, the raw materials in this method are the same as the raw materials o...
