preparation example Construction

[0076] In the above-mentioned process, the preparation method of described CT solution comprises the steps:

[0077] The mixture of binder resin, charge transport material and additives is dissolved according to the solid ratio of 1:1-10 to prepare a charge transport layer material solution.

[0078] The charge transport material is polyethylene resin, acrylic resin, polyamide resin, polycarbonate, polyimide resin, vinyl chloride resin, vinyl acetate resin, phenolic resin, polyacrylamide resin, polyurethane resin, polyvinyl alcohol One or more of acetal resin, polyvinyl alcohol resin, polyurethane resin, polyacrylic resin, polyvinylpyridine resin, and water-soluble polyester resin.

[0079] The binder resin is one or more of polycarbonate resin, acrylic resin, polyacrylonitrile resin, phenolic resin, and copolymerized aromatic hydrocarbon resin.

[0080] The additive is any one or more of acrylates, organosiloxane compounds, fatty ether compounds and aminopropene compounds. ...

Embodiment 1

[0093] The first step is to configure CT stripping solution, CT stripping solution, and UC stripping solution respectively.

[0094] The CT stripping solution is a mixture of tetrahydrofuran 60% and toluene 40%; the CG stripping solution is a mixture of butanone 40% diethylene glycol methyl ether 60%; the UC stripping solution is isopropanol 70% and xylene 30%. of the mixture.

[0095] In the second step, the charge blocking layer material solution, the charge generation layer material solution and the charge transport layer material solution are respectively prepared.

[0096] 2-1. Mix and dissolve 30 g of alcohol-soluble nylon resin (, 400 g of ethanol at 50° C. for 4 hours, and prepare a charge blocking material solution for later use.

[0097] 2-2. Mix 15g of titanyl phthalocyanine, 30g of polyethylene glycol butyral (manufactured by Kuraray, Japan, model 120s), and 800g of toluene, grind for 4 hours, and disperse uniformly by ultrasonic to prepare a charge generation mat...

Embodiment 2

[0102] In addition to the configuration process of the charge transport material solution in step 2-3, N, N'-diphenyl-N, N'-bis(4-methylphenyl)-4,4'-biphenyldiamine was changed to It is 50, 200g polycarbonate resin, except that the final film thickness of the charge transport layer is changed to 16um, everything else is the same as that of embodiment 1.

Abstract

The invention discloses a PIP intelligent regeneration method. The method comprises the following steps: judging, stripping and repairing, respectively preparing a CT stripping solution, a CG stripping solution and a UC stripping solution, respectively preparing a charge barrier layer material solution, a charge generation layer material solution and a charge transport layer material solution, and selectively coating to realize the regeneration of an organic photoconductor. The preparation method disclosed by the invention is high in pertinence, and PIP recoating regeneration can be carried out according to actual conditions; a process is clear, the process and intelligent degree in each operation step is high, large-scale popularization and application of processing enterprises are very convenient, and a use and popularization value is very high; and the organic photoconductor recoated and regenerated by the method is good in printing effect, the thickness of the charge transport layer can be controlled in a large range, and the service life of the product can be effectively prolonged. When continuous ultra-high-speed printing is carried out, obvious light color and cross color do not exist, and the problems of ghosting and the like easily occurring in high-speed printing do not exist.

Description

technical field [0001] The invention discloses a PIP intelligent regeneration method, which belongs to the technical field of organic photoconductor processing. Background technique [0002] Organic Photoconductor (OPC) is the core component of modern office equipment such as copiers, laser printers, laser fax machines and multi-functional digital all-in-one machines. It is mainly used to realize photoelectric conversion and imaging technology. A photoelectric conversion device formed by coating an organic photoconductive material layer. As disclosed in patents CN200910032466.9 and CN201811116732.1, an organic photoconductor generally includes a conductive substrate, and layers coated on the surface of the conductive substrate sequentially from the inside to the outside. charge blocking layer, charge generation layer and charge transport layer. [0003] In the prior art, most photoelectric conversion devices of this type are made of an aluminum tube substrate and are used i...
