Problems solved by technology

[0002] Existing organic photoconductive drum coating fluids and coatings have cumbersome preparation processes. These coatings are not easy to preserve during the production process, and are prone to problems such as sedimentation, crystallization, and solidification that affect use; or in the existing preparation process, the original coating Some physical and chemical properties are destroyed, making the coating lose its proper photoelectric performance after use
Moreover, the existing organic photoconductor drum has long been prone to problems in the printing process.
In order to solve the problem that organic photoconductive drums are prone to spots in the printing process for a long time, more manufacturers use oxidized drum bases as drum bases, which cost a lot

Abstract

The invention discloses a four-layer coating process of an organic photosensitive drum and the organic photosensitive drum prepared by adopting the four-layer coating process. The four-layer coating process comprises the following steps of: 1, forming a carrier barrier layer on a drum base of the organic photosensitive drum; 2, forming a carrier barrier layer 2 on the carrier barrier layer 1, a carrier forming layer coating 2 contains titanium dioxide, titanium yellow and nylon; 3, forming a carrier generating layer on the carrier barrier layer 2, wherein the carrier generating layer contains titanyl phthalocyanine and polyvinyl butyral resin with the weight proportion of 1:1-1.5:1; and 4, forming a carrier transmission layer on the carrier generating layer. According to the four-layer coating process, the coating cost can be controlled to be below ** / pcs, and the relatively high production cost pressure of a manufacturer is relieved.

Description

technical field [0001] The invention relates to an OPC organic photoconductive drum, in particular to a four-layer coating process for an organic photoconductive drum and the prepared organic photoconductive drum. Background technique [0002] Existing organic photoconductive drum coating fluids and coatings have cumbersome preparation processes. These coatings are not easy to preserve during the production process, and are prone to problems such as sedimentation, crystallization, and solidification that affect use; or in the existing preparation process, the original coating Some physical and chemical properties are destroyed, so that the used coating loses its proper photoelectric performance. Moreover, the existing organic photoconductor drum has long been prone to problems in the printing process.
