Development of Fire-Resistant Phosphate Adhesive Based on Alumina and Aluminosilicate Dispersed Industrial Waste

The results of studying the possibility of producing fire-resistant phosphate glue based on aluminosilicate and high-alumina industrial waste are presented. Using the methods of physico-chemical analysis, the phase composition of cured adhesive structures was studied, and the change in the composition after drying and firing was analyzed. Disperse-filled fire-resistant liquid adhesives were obtained that remain stable for at least 90 days. The main properties of adhesive refractory compositions are provided. The maximum application temperature of such materials was found to be 1700°C.
