Abstract

The invention discloses a ground color-free three-layer coating process and an organic photosensitive drum prepared by adopting the ground color-free three-layer coating process. The ground color-free three-layer coating process comprises the following steps of: 1, coating a carrier barrier layer coating on a drum base of the organic photosensitive drum to form a carrier barrier layer, wherein the carrier barrier layer coating is prepared by adopting the step of preparing nylon rein into a solution with a solid content of 3.5-5.5 percent by adopting a solvent; 2, coating a carrier forming layer coating on the carrier barrier layer to form a carrier forming layer, the carrier forming layer coating contains titanyl phthalocyanine and polyvinyl butyral resin with a proportion of 1:1-1.5:1; and 3, coating a carrier transmission layer coating on the carrier forming layer to form a carrier transmission layer. According to the ground color-free three-layer coating process, the coating cost can be controlled to be below ** / pcs, and the high production cost pressure of a manufacturer is greatly relieved.

Description

technical field [0001] The invention relates to an OPC organic photoconductive drum, in particular to a three-layer coating process without background color and the prepared organic photoconductive drum. Background technique [0002] The existing organic photoconductive drum coating liquid coatings may have cumbersome preparation processes, and these coatings may not be easy to preserve during the production process, and there are problems such as sedimentation, crystallization, and solidification that affect the use. At the same time, the existing coating liquid coatings often imitate The color of the OEM original drum core, the appearance of the photosensitive drum is not bright enough, not innovative enough, and cannot meet the aesthetic requirements of some customers. [0003] Therefore, a three-layer coating process without background color was developed, which can reduce the cost and have the same photoelectric parameters as the original performance, and at the same ti...
