Processing method of electronegative multilayer OPC drum

Abstract

The invention discloses a processing method of an electronegative multilayer OPC drum. The processing method comprises the following steps that S1, a dispersing agent, an anti-settling agent and titanium dioxide are taken, a mixture containing one or more of phenolic resin, acrylic resin and nylon resin is added to an alcohol solution, and a charge blocking layer material solution is prepared; S2,a charge generating layer material solution and a charge transmission layer material solution are prepared; S3, pretreatment is carried out on a pixel pipe, and successively the surface of the pixelpipe is subjected to coating in sequence, so that a charge blocking layer, a charge generating layer and a charge transmission layer are sequentially formed on the surface of the pixel pipe from inside to outside; and S4, stepped baking is carried out on the pixel pipe, then the pixel pipe is taken out for aging, and the finished OPC drum is obtained. According to the processing method of the electronegative multilayer OPC drum, modification is carried out on the charge blocking layer material arranged on the OPC drum in a coating manner, and the thixotropic property of the material solution is improved, so that the good sagging property is achieved when the coating thickness is relatively thick, and the uniformity of the subsequent coating is guaranteed when the thickness of the charge blocking layer is increased.

Description

technical field [0001] The invention relates to an OPC drum and a corresponding processing method thereof, in particular to a processing method of a negatively charged multilayer OPC drum, belonging to the technical field of organic photoconductors. Background technique [0002] Organic Photoconductor (OPC) is an important material widely used in laser printing, digital copying and other industries. OPC drum is a photoelectric conversion device formed by coating OPC material on the surface of a conductive aluminum cylinder. Its characteristics are It is an insulator in the dark, which can maintain a certain static charge. When irradiated by light of a certain wavelength, it becomes a conductor and releases the charge through the aluminum base, finally forming an electrostatic latent image. As the heart part of the laser printing system, the surface condition of the OPC drum has a direct impact on the use of the laser printing system, which directly determines whether the las...

Problems solved by technology

However, in the actual application process, technicians found that due to the general sagging performance of the current charge blocking layer material, increasing the thickness of the charge blocking layer on the surface of the OPC drum will lead to poor uniformity of the subsequent coating of the product, thereby affecting the product.
