Problems solved by technology

Although the latter can print realistic graphics and texts, it consumes a lot of ink and has a high cost of use. Moreover, the color of graphics and texts printed with ink tends to fade and the storage time is short, so it is difficult to adapt to the printing needs of documents that need to be stored for a long time.

Embodiment 1

[0016] Select 75 parts of resin, 0.5 parts of polypropylene wax, 0.5 parts of blue pigment, 0.5 parts of charge regulator 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 modifier is a metal azochrome compound.

[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.

Abstract

The invention relates to a blue carbon powder and its manufacturing method. It is made by mixing 75-98 parts resin, 1-10 parts polyacrylic wax or polyethylene wax, 1-1. 5 yellow pigment, 0.5-10 electric charge regulator, 0.1-1 part earth silicon, through extruding, coarse crushing and fine crushing. Matching blue carbon powders with black, red and blue ones, it can simplify printing process, improve working efficiency, and reduce printing cost, applicable for long time preservation of archives.

Description

technical field [0001] The invention relates to a carbon powder and a preparation method thereof. Specifically, blue toner for electrostatic copiers, laser printers, facsimile machines and printing machines and a preparation method thereof. Background technique [0002] At present, black toner is the most common toner used in xerographic copiers, laser printers, fax machines and printing presses. Using black toner to copy, print, receive and print out graphics is pure black, and the color is relatively monotonous, which cannot meet people's needs for color graphics. For this reason, the color printing machine that utilizes color ink to perform color printing and the inkjet printer that utilizes color ink to perform color printing have appeared in recent years. Although the use of colored inks and colored inks can achieve color printing and color printing, the former needs to use four inks of different colors for four overprints, and also needs to carry out photo-plate maki...
