  • Patent number: 11866612
    Abstract: A preparation method for a phosphate-based high-temperature-resistant adhesive self-reinforced by in-situ growth and locking of flaky kyanite is provided, including: preparing a modified filler by using bauxite, kaolin, boric acid and boric oxide, and taking a reaction solution of diluted phosphoric acid and aluminum hydroxide powder as latex liquid, and mixing the modified filler, the latex liquid, and silicon powder to prepare the adhesive. After being treated at 700° C., kyanite grows within the adhesive. As the treatment temperature increases, the size and content of the kyanite are further increased, thereby forming a locking and reinforcing structure. After being treated at 1100° C., the bonding strength of the adhesive reaches up to about 50 MPa, and the adhesive illustrates excellent high-temperature-resistant bonding strength.
