[0059]In a second aspect of the invention, a method of preparing a metal effect material is provided, including the following steps:
[0060]S1: Add acrylate copolymers, acrylate polymers, and polystyrene series high molecular polymers to high mixing machines, using a velocity of 350-450 rpm;
[0061]S2: Then add metal powder, pearlite, antioxidants, lubricants, mix, and form premixing to S1.
[0062]S3: The premix obtained by step S2 is added to the double screw extruder feed port extruded into the granulation, that is, it is obtained.
