Embodiment 1
[0016] Choose 75 parts of resin, 1 part of polypropylene wax, 0.5 parts of blue pigment, 0.5 parts of charge modifier and 0.2 parts of silica. The resin is a binary copolymer resin formed by reacting according to the weight ratio of styrene: butyl methacrylate=4:1. Said charge regulator is metal chromium salicylate.
[0017] Pour the resin, polypropylene wax, blue pigment and charge regulator together into the mixer and mix evenly to make a mixture.
[0018] Then put the mixture into the extruder, extrude at a temperature of 116° C., and pulverize it into a powder with a coarse powder machine.
[0019] After that, use a fine powder machine to pulverize the above powder into 3-11 μm powder;
[0020] Finally, pour the above crushed powder into a mixer, add silicon dioxide and mix evenly to obtain blue toner.
Embodiment 2
[0022] Select 88 parts of resin, 6.5 parts of polyethylene wax, 1.0 part of blue pigment, 5 parts of charge regulator and 0.6 parts of silica. The resin is a binary copolymer resin formed by reacting according to the weight ratio of styrene: butyl methacrylate=4:1. Said charge modifier is a metal azochrome compound.
[0023] Pour the resin, polyethylene wax, blue pigment and charge regulator together into the mixer, and mix evenly to make a mixture.
[0024] Then put the mixture into the extruder, extrude it at a temperature of 135° C., and pulverize it into powder with a coarse powder machine.
[0025] After that, use a fine powder machine to pulverize the above powder into 3-11 μm powder;
[0026] Finally, pour the above crushed powder into a mixer, add silicon dioxide and mix evenly to obtain blue toner.
Embodiment 3
[0028] Select 98 parts resin, 10 parts polypropylene wax, 1.5 parts blue pigment, 10 parts charge regulator and 1 part silica. The resin is a binary copolymer resin formed by reacting according to the weight ratio of styrene: butyl methacrylate=4:1. Said charge regulator is metal chromium salicylate.
[0029] Pour the resin, polypropylene wax, blue pigment and charge regulator together into the mixer and mix evenly to make a mixture.
[0030] Then put the mixture into the extruder, extrude it at a temperature of 155° C., and pulverize it into powder with a coarse powder machine.
[0031] After that, use a fine powder machine to pulverize the above powder into 3-11 μm powder;
[0032] Finally, pour the above crushed powder into a mixer, add silicon dioxide and mix evenly to obtain blue toner.
