NOVELTY - A waterproof coating comprises 32-38 pts. wt., preferably 35 pts. wt. modified styrene-acrylic emulsion, 22-28 pts. wt., preferably 25 pts. wt. fly ash, 14-18 pts. wt., preferably 16 pts. wt. graphene oxide powder, 12-18 pts. wt., preferably 15 pts. wt. mixed rare earth ore, 6-10 pts. wt., preferably 8 pts. wt. mixed metal oxide, 4-8 pts. wt., preferably 6 pts. wt. mica powder and 1-3 pts. wt., preferably 2 pts. wt. dispersing agent. The modified styrene-acrylic emulsion comprises 28-34 pts. wt. styrene-acrylic emulsion, 14-28 pts. wt. polystyrene microspheres, 4-8 pts. wt. tert-butyl peroxybenzoate, 1-3 pts. wt. silane coupling agent KH-560 (RTM: gamma -glycidoxypropyltrimethoxysilane) and 12-18 pts. wt. ethanol. USE - Waterproof coating. ADVANTAGE - The waterproof coating has excellent corrosion resistance, strong adhesion on a metal surface, and high utilization value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of waterproof coating, which involves (S1) weighing the raw materials, (S2) sequentially adding graphene oxide powder, mica powder, mixed rare earth ore and mixed metal oxide to ultrasonic cell pulverizer, ultrasonically processing to obtain mixture (A), (S3) adding modified styrene-acrylic emulsion, fly ash and dispersing agent to magnetic stirrer, stirring at 155-175 rpm for 25-35 minutes, transferring mixture (A) to magnetic stirrer and stirring at 215-235 rpm for 3-6 hours.
