AI Technical Summary
Existing adhesives cannot be used at high temperatures, which limits the application of foamed ceramics in aerospace, military, and metallurgical fields, especially in high-temperature environments above 800°C where the bonding strength cannot be guaranteed.
A foamed ceramic adhesive capable of withstanding 800℃ was prepared by using a mixture of basalt, sepiolite, sodium carbonate, boron nitride, iron oxide, fluorite, and other components with a mixed solution of polyvinyl alcohol, sodium carboxymethyl cellulose, and water. The adhesive was then bonded and sintered through specific process steps.
Maintaining bond strength at 800℃, reducing sintering temperature and time ensures that the high-temperature performance of foamed ceramic components is not affected, while preserving excellent properties such as lightweight, heat insulation, waterproofing, temperature resistance, and impact resistance.
