Organic photoconductor drum coating process and photoconductor drum prepared by same

Abstract

The invention provides an organic photoconductor drum coating process and a photoconductor drum prepared by the organic photoconductor drum coating process, and the organic photoconductor drum is excellent in photoelectric property, stable in coating liquid, free of crystallization, high in product blackness, high in wear resistance and low in manufacturing cost. The photoconductor drum is prepared by the following steps: coating a carrier barrier layer coating on the drum base to form a carrier barrier layer, wherein the carrier barrier layer coating contains titanium dioxide and nylon resin,and the mass ratio of the titanium dioxide to the nylon resin is 1.8: 1; the carrier barrier layer being coated with a carrier generation layer coating to form a carrier generation layer, the carriergeneration layer coating containing oxotitanium phthalocyanine and polyvinyl butyral resin, and the ratio of oxotitanium phthalocyanine to polyvinyl butyral resin being 1.15: 1; and, coating a carrier transport layer coating on the carrier generation layer to form a carrier transport layer. The method is applied to the technical field of printing.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an organic photoconductive drum coating process and the prepared photosensitive drum. Background technique [0002] The core photoelectric conversion and imaging components in modern office equipment are indispensable core tools in our modern office printing. The current photoconductive drum is not easy to preserve, and the photoconductive performance is poor. The effect of base injection into the photosensitive layer, and the transmission performance is low. And the prior art photosensitive drum coating solution, paint or the preparation process is cumbersome, these paints are not easy to preserve during the production process, there are problems such as sedimentation, crystallization and solidification that affect the use, or appear in the existing preparation process. Destroy the original physical and chemical properties of the coating, making the coating lose its proper pho...

[0002] The core photoelectric conversion and imaging components in modern office equipment are indispensable core tools in our modern office printing. The current photoconductive drum is not easy to preserve, and the photoconductive performance is poor. The effect of base injection into the photosensitive layer, and the transmission performance is low

And the prior art photosensitive drum coating solution, paint or the preparation process is cumbersome, these paints are not easy to preserve during the production process, there are problems such as sedimentation, crystallization and solidification that affect the use, or appear in the existing preparation process. Destroy the original physical and chemical properties of the coating, making the coating lose its proper photoelectric performance after use

Although some domestic manufacturers have developed a low-cost process with similar photoelectric performance to the original one, there is still a certain gap with the original one.
