Abstract

The invention relates to a high-definition digital white negatively-charged toner and a preparation method thereof, and belongs to the technical field of preparation of white toners. The preparation method comprises the following steps: firstly uniformly mixing a titanium dioxide pigment, polyester resin, carnauba wax and a charge regulator, then extruding into a flake, crushing, continuing to add alkyl silane, dimethyldichlorosilane and titanium oxide to obtain mixed semi-finished powder, and finally sieving to obtain the high-definition digital white negatively-charged toner. Through adoption of the toner prepared by the preparation method provided by the invention, a designer and an image studio can conveniently give full play to creativeness and can print white on a dark medium at will; the designer can achieve fast printout on various medium types such as smooth photo paper, fiber paper, a T-shirt transfer medium, transparent sticker and the like so as to obtain a perfect effect close to an actual design and print the design.

Description

technical field [0001] The invention relates to a high-definition digital white negatively charged toner and a preparation method thereof, in particular to a white negatively charged toner for a digital five-color printer and a preparation method thereof, and belongs to the technical field of white toner preparation. Background technique [0002] In the past, white toner products were based on inkjet, dye sublimation, and image transfer technologies. Therefore, the price of the product is often very high, and the time spent on maintenance is also very long. [0003] White toner machines are quite different from traditional products. These machines have more functions and are easier to operate. Because they eliminate dehydration time, the entire process is faster, resulting in a more cost-effective printing experience. [0004] Before this, none of the laser printers we came into contact with could print white patterns or text. Since ordinary pigments absorb certain frequ...
