Problems solved by technology

[0002] Existing glues generally do not have good high temperature resistance, which makes these glues unsuitable for some high temperature workshops. These high temperature workshops cannot find suitable glue for use, which brings great trouble to the factory
[0003] At the same time, some high-temperature equipment, such as furnaces, boilers, and reactors, are equipped with inorganic glue because of their high operating temperature. However, inorganic glue generally has many problems such as low bonding strength, easy peeling and warping

Abstract

The invention provides ametal surface oxidation-resistant high-temperature glue and a preparation method thereof. The metal surface oxidation-resistant high-temperature glue comprises: a component A including lithium silicate, potassium fluosilicate, sodium silicate, polyphosphoric acid and water; a component B including polyvinyl alcohol, a silane coupling agent, magnesium oxide and anhydrous calcium chloride; and a component C including potassium dihydrogen phosphate, 3000-mesh mesoporous carbon and perfluoroalkyl vinyl ether. The adhesiveness of the glue at a high temperature, especially tometal, is improved, and the glue does not peel off or warp after long-term use at high temperature.

Description

technical field [0001] The invention belongs to the field of glue materials, in particular to a metal surface oxidation-resistant high-temperature glue and a preparation method thereof. Background technique [0002] Existing glues generally do not have good high temperature resistance, which makes these glues unsuitable for some high-temperature workshops. These high-temperature workshops cannot find suitable glue for use, which brings great trouble to the factory. [0003] At the same time, some high-temperature equipment, such as furnaces, boilers, and reactors, are equipped with inorganic glue because of their high operating temperature. However, inorganic glue generally has many temperatures such as low bonding strength, easy peeling and warping. Contents of the invention [0004] The invention provides a metal surface oxidation-resistant high-temperature glue and a preparation method thereof. By improving and adjusting the formula and combination of the prior art, the...
