Problems solved by technology

The conductive fillers added in the above-mentioned patents all have a limitation on the amount of addition. When the amount of addition is small, the coating has little effect on the overall appearance, color, and mechanical properties of the rubber roller, and there will be no precipitation, whitening, etc. on the surface of the rubber body. problems such as frost, but the high conductivity of the developing roller and charging roller is basically difficult to satisfy
When too much conductive filler is added to meet high conductivity, inorganic fillers such as carbon black, graphite, metal fiber, and metal powder are generally not only prone to sedimentation and poor uniformity and stability, but also have problems such as excessive addition of the rubber roller. degree, resilience and hardness have a great influence
However, when too much small molecule salt is added, problems such as precipitation on the surface of the main material and white frost will easily occur.
All of these have had a great impact on the high-quality printout and the overall performance of the device, making it difficult to meet the requirements for high-quality draft printing and high-definition

Abstract

The invention provides an ionic liquid nanolayer of a laser printer rubber covered roller. The ionic liquid nanolayer contains a micromolecular ionic liquid or ionic liquid polymer or the mixture of the liquid or/and the polymer and dispersion liquid. The laser printer rubber covered roller comprise a rubber covered roller rubber body and an outer-layer coating, wherein the ionic liquid nanolayer is arranged between the rubber covered roller rubber body and the outer-layer coating and is 0.1-200 nm in thickness. A preparation method of the laser printer rubber covered roller comprises the steps that the rubber covered roller provided with a rubber layer is cleaned in a standardized mode; then the rubber covered roller is blow-dried for plasma treatment; then the rubber covered roller is put on a dip-coating machine and is dipped with ionic liquid to form the nanolayer, the periphery of the rubber covered roller is dried and is sprayed with a conductive coating. The ionic liquid nanolayer can form a double electrode layer structure between conductive rubber and the conductive coating, the conductive performance of the laser printer rubber covered roller is further improved, the conductive performance of the laser printer rubber covered roller can be stabilized, a system is stable and homogeneous, and accordingly high-quality printed rough sketch output is provided.

Description

technical field [0001] The invention belongs to the technical field of laser imaging, and in particular relates to an ionic liquid nano-layer for a rubber roller of a laser printer, a rubber roller with the ionic liquid nano-layer and a preparation method for the rubber roller. Background technique [0002] The core imaging device of a laser printer is the toner cartridge, and the developing roller and the charging roller are one of the important components. When the developing roller is working, it mainly absorbs the toner through the charge on the surface of the rubber roller. After the printing data is converted and processed, it is converted into a corresponding laser signal. The charging roller is used to charge the toner cartridge, and then refracted to the OPC surface through the prism to complete the process. Subsequent printouts work. Therefore, complete and high-quality drawing output has strict requirements on the stable and high conductivity of the charging roll...
