NOVELTY - Preparation method of anticorrosive coating involves (i) mixing 10-20 pts. wt. lime powder, 5-10 pts. wt. silicon dioxide, 10-20 pts. wt. m-xylene and 5-10 pts. wt. aluminum dihydrogen tripolyphosphate, and curing to obtain a cured system, (ii) adding 5-10 pts. wt. graphene to the cured system, and ultrasonically treating for 40-20 minutes, and (iii) mixing the system after the ultrasonic treatment with 20-40 pts. wt. acrylic acid ester polymer emulsion, and stirring for 10-30 minutes to obtain the product. USE - The method is useful in preparation of anticorrosive coating. ADVANTAGE - The anticorrosive coating improves the anti-corrosion performance of the surface of metal product, is healthy, non-toxic and harmless to human health.
