[0046] 1) Preparation of special effect toner:
[0047] Add the special effect pigment with a particle size of 10 to 50 microns into the aqueous solution of the emulsifier, and use an ultrasonic disperser to disperse. After ultrasonic dispersion for 10 minutes, install a stirrer and a heating device, heat up to 80 ° C, add an initiator, and drip Add a certain amount of mixed monomers of methyl methacrylate and acrylic acid to carry out emulsion polymerization, and keep the temperature for 30min after dropping the monomers to obtain special effect toner coated with organic film.
[0048] 2) Preparation of metal-like appearance polypropylene-sarin resin composite material:
[0049] After mixing polypropylene, sarin resin, toughening agent, antioxidant and lubricant evenly, add it into the twin-screw extruder, and then add the special effect toner after 1) treatment and the reinforcing agent in the formula ratio And light stabilizer is added from the side feeding place, melted a...
