Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-soluble inorganic high-temperature-resistant silicate anticorrosion coating and a preparation method thereof. Background technique [0002] High-temperature corrosion of metal materials is one of the urgent problems to be solved in the use of metal materials. Modern petroleum, chemical industry, metallurgy, aerospace, nuclear energy and other engineering technologies are also inseparable from the problem of high-temperature corrosion. In the power industry, pipes in Anti-corrosion protection at high temperature is particularly important to prolong the life of pipes. The purpose of developing high-temperature-resistant coatings is to protect the surface of materials in high-temperature environments. With the development of modern industrial technology, equipment in chemical industry, metallurgy, electric power and other industries are under the test of high temperature all the tim...
