Description

technical field [0001] The invention relates to the technical field of high-temperature glue, in particular to a high-temperature glue for ceramic materials and its preparation method and application. Background technique [0002] High-temperature glue is a high-temperature-resistant inorganic nanocomposite binder made of inorganic nanomaterials through polycondensation reaction. Through the screening of the composition ratio and preparation process parameters, the binder is a suspension dispersion system with a neutral pH value. , not only has strong adhesion and is non-corrosive to metal substrates, but also can maintain good adhesion performance and corrosion resistance at high temperatures, and has a long service life. High-temperature glue is easy to use and can be used for direct bonding of high-temperature resistant materials. The paint can be directly sprayed on the surface of a high-temperature substrate at 400-1000°C. When the water volatilizes, the paint will inst...
