DETAILED DESCRIPTION - Preparing polyurethane thermally conductive anti-corrosion coating involves adding isophorone diisocyanate and polypropylene glycol to stirring device through feed port according to preset ratio, and central control unit starts stirring device to make stirring device stir isophorone diisocyanate and polypropylene glycol. During stirring process, central control unit adds hydrophilic chain extender and acetone into stirring device to emulsify to prepare water-based polyurethane emulsion. The MIS modified graphene oxide dispersion is added into water-based polyurethane emulsion through feeding port to prepare polyurethane mixture. The film-forming aid, defoaming agent and dispersant are added to mixture through feeding port, and central control unit controls stirring device to heat mixture and perform constant temperature stirring to obtain polyurethane thermal conductive anti-corrosion coating. The central control unit is preset with total amount of standard particulate matter R0. The central control unit obtains actual total amount of particulate matter R measured by ultrasonic device, and compares R with total amount of standard particulate matter R0. The comparison results determined whether total amount of particulate matter meets standard. If central control unit determines that total amount of particulate matter meets standard, central control unit determines that coating preparation is completed. If central control unit determines that total amount of particulate matter does not meet standard, central control unit calculates difference between total number of particles is DeltaR, and speed of stirring part is adjusted to corresponding value according to R. When central control unit determines that total number of particles does not meet standard, central control unit obtains real-time measurement of distance S between adjacent particles by ultrasonic device, and compares S with preset distance S0 between adjacent particles to determine particle Whether to aggregate, when central control unit determines that particles are aggregated, central control unit obtains number Q of particles in aggregates measured by ultrasonic device, and compares Q with preset aggregated particle quantity interval Q0 to determine aggregation After determination is completed, central control unit acquires position of aggregate and adjusts angle of stirring part according to position of aggregate.
