▎ 摘　　要

NOVELTY - A high temperature resistant and easy-cleaning inorganic coating comprises modified silicate, phosphate, ceramic material, metal powder, cobalt oxide, graphite and polyethylene glycol. USE - The high temperature resistant and easy-cleaning inorganic coating is used in the surface coating of inner furnace walls, pipelines, reaction kettles or cooker (claimed). ADVANTAGE - The inorganic coating is easy to clean, use and operate, safe and environmentally-friendly, has high temperature resistant property and low surface tension, solves the problems of powdering, discoloration and cracking of the coating at high temperature, and the hydrophobic and oleophobic properties of inorganic materials solves the problem of poor cleaning, does not contain volatile organic substances, does not emit any volatile organic compound, can meet the coating requirement once and has a circular hole structure and strong regularity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a preparation method of the high temperature resistant and easy-cleaning inorganic coating comprising firstly preparing modified silicate and phosphate into a modified silicate aqueous solution and a phosphate aqueous solution and uniformly mixing the modified silicate aqueous solution, the phosphate aqueous solution and other raw materials to obtain the high temperature resistant and easy-cleaning inorganic coating, where the concentration of the modified silicate aqueous solution is 20-40 wt.% and the concentration of the phosphate aqueous solution is 25-50 wt.%; and a high temperature resistant and easy-cleaning inorganic coating is obtained by spraying and sintering.
