Problems solved by technology

[0002] At present, the pigment component of the black toner used in ordinary laser printers or color laser printers is magnetic powder, and its color has persistence, while the toner of red, yellow, and blue color toners is organic pigment, and the color persistence is poor. The color graphics and printed red stamps printed by laser printer toner can not guarantee the durability of writing

Abstract

The invention relates to a red carbon powder for laser printers, which consists of 4-8 parts by weight of nano-iron oxide red, 2-4 parts by weight of nano-iron oxide yellow, 8-25 parts by weight of ultraviolet fluorescent powder, and 78-95 parts by weight of polyester resin , 1-10 parts by weight of polypropylene wax, 1-5 parts by weight of salicylic acid metal zinc complex charge regulator, 1-4 parts by weight of dimethyldichlorosilane and 5-8 parts by weight of hexamethyldisilazide Its composition is alkane; its preparation method is that the above raw materials are mixed, kneaded, extruded, multistage crushed, separated and surface modified. Using the red toner for laser printers of the present invention to be used in common laser printers and color laser printers, the printed file graphics can be preserved for a long time; To the security anti-counterfeiting effect.

Description

technical field [0001] The invention relates to a carbon powder and a preparation method thereof. In particular, it relates to a red toner for a durable encrypted safe laser printer and a preparation method thereof for printing archival graphics, red anti-counterfeiting seals or color graphics with an ordinary laser printer or a color laser printer. Background technique [0002] At present, the pigment component of the black toner used in ordinary laser printers or color laser printers is magnetic powder, and its color has persistence, while the toner of red, yellow, and blue color toners is organic pigment, and the color persistence is poor. The color graphics and printed red stamps printed by laser printer toner cannot guarantee the durability of handwriting. [0003] In order to solve the technical problems of long-term preservation of electronic signature seals and archive graphics in the official document issuance system printed by ordinary laser printers and color las...
