NOVELTY - Preparing high thermal conductivity thermoplastic powder coating with uniform particle size distribution involves grinding the soluble salt first, adding the thermoplastic polymer and graphene microchips into the high-speed mixer to disperse, extruding and granulating through the screw extruder to obtain a composite thermoplastic polymer. The composite thermoplastic polymer prepared is pulverized using a jet mill, and then classified and sieved using a screen to obtain a fine polymer. The fine polymer prepared is washed, then dried by a spray dryer, and then passed through a 100 mesh screen to obtain a high thermal conductivity thermoplastic powder coating with uniform particle size distribution. USE - Method for preparing high thermal conductivity thermoplastic powder coating with uniform particle size distribution. ADVANTAGE - The method enables to prepare high thermal conductivity thermoplastic powder coating with uniform particle size distribution has heat conducting performance, and coating film more uniformly.
