Coating special for cooling tower corrosion prevention

The invention provides a coating special for cooling tower corrosion prevention. The coating is prepared from 15-45 parts of titanium dioxide, 6-15 parts of barium sulfate, 15-45 parts of light calcium carbonate, 10-30 parts of talcum powder, 15-20 parts of rubber powder, 5-10 parts of quartz and an appropriate amount of a pigment. A preparation method comprises the steps that titanium dioxide, barium sulfate, light calcium carbonate, the talcum powder, the rubber powder, quartz and the like are precisely metered and then added into a reaction kettle, a shearing emulsifying machine is started, the raw materials are mixed for one hour at the speed of 1,400 revolutions per minute, then the speed is increased to 2,800 revolutions per minute for high-speed shearing, and when the viscosity and the fineness meet the standard, filtering, filling and finished product warehousing are conducted. The coating is innovative in technology, low in investment and capable of rapidly achieving the effects and achieving continu
