NOVELTY - Producing anticorrosive coating comprises e.g. crushing the barite, sieving, and filtering the sieve with 150-200 meshes sieve, adding polytetrafluoroethylene and scaly graphene into the pulverized barite, and mixing PTFE and scaly graphene at a weight ratio of 1:1-12:1, stirring to make it evenly mixed, allowing to stand the mixed solution for precipitation, drying the precipitate and crushing to obtain powder A, mixing nano-silicon carbide, graphite, black stone powder, heavy stone powder, yttrium oxide, accelerator, curing agent and water evenly, stirring and reacting to obtain a mixed solution-B, and adding powder A into mixed solution B, adding curing agent and heating to 160 degrees C, stirring for 4-18 hours at a stirring speed of 500 revolutions/minute, cooling, drying, grinding and crushing. USE - The method is useful for producing anticorrosive coating. ADVANTAGE - The coating can withstand the oxidative corrosion of strong oxidizing materials e.g. strong intermediates of concentrated acid solutions and polar solvents for a long time, prevents the physical and chemical reactions of acid-base corrosive media; and has high hardness, impact resistance, smoothness and fullness, and characteristics of high thermal shock resistance and good adhesion. DETAILED DESCRIPTION - Producing anticorrosive coating comprises (a) taking 12-33 pts. wt. barite, 6-19 pts. wt. polytetrafluoroethylene, 7-13 pts. wt. scaly graphene, 4-17 pts. wt. nano-silicon carbide, 6-15 pts. wt. graphite, 4-14 pts. wt. black stone powder, 4-18 pts. wt. heavy stone powder, 7-15 pts. wt. yttrium oxide, 2-9 pts. wt. accelerator, 3-8 pts. wt. curing agent and 60-70 pts. wt. water, (b) crushing the barite, sieving, and filtering the sieve with 150-200 meshes sieve, (c) adding polytetrafluoroethylene and scaly graphene into the pulverized barite, and mixing PTFE and scaly graphene at a weight ratio of 1:1-12:1, stirring with a speed of 500 revolutions/minute for 5-12 hours to make it evenly mixed, (d) allowing to stand the mixed solution for precipitation, drying the precipitate and crushing to obtain powder A, (e) mixing nano-silicon carbide, graphite, black stone powder, heavy stone powder, yttrium oxide, accelerator, curing agent and water evenly, stirring and reacting in the reactor at 115-135 degrees C for 60- 90 minutes to obtain a mixed solution-B, and (f) adding powder A into mixed solution B, adding curing agent and heating to 160 degrees C, stirring for 4-18 hours at a stirring speed of 500 revolutions/minute, cooling, drying, grinding and crushing.
