Problems solved by technology

[0006] Through the above search analysis, it can be seen that the existing AB inorganic adhesives lack the addition of glycerin and methyl cellulose at the same time, resulting in poor curing effect and surface finish of the adhesive, while the metal oxides in the existing inorganic adhesives The structure is not dense, which makes the mixing effect unsatisfactory, resulting in poor high temperature resistance and heat insulation effect, so it is still necessary to further improve

Abstract

The invention provides a high-temperature-resistant inorganic adhesive which comprises a component A and a component B. The component A comprises silicate, distilled water, methyl cellulose and glycerol; and the component B comprises metal oxide, ceramic microspheres and bentonite. The invention also provides a preparation method of the inorganic adhesive. The method comprises the following steps: preparation of the component A, preparation of the component B, and mixing of the component A and component B. By adding the glycerol and methyl cellulose, the component A glue solution has favorable moisturizing function, and prevents the glue from curing due to volatilization at room temperature. The component A in use performs favorable improving functions on the surface gloss of the inorganic glue after curing. The component B is prepared by calcination, cooling, grinding and screening in the preparation process, so that the metal oxide has more compact structure, and the powder is finer.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to a high-temperature-resistant silicate inorganic adhesive and a preparation method thereof.
