Problems solved by technology

Specifically, electronically conductive rubber is less affected by changes in environmental conditions during preparation, so the resistance of the transfer roller made from it will not change greatly with the change of kneading temperature and time, so that by The resistivity of the prepared rubber can be controlled by adjusting the proportion, but the resistance of the electronically conductive rubber is greatly affected by the voltage change, for example, there will be large fluctuations in the resistivity under the voltage of 1000V or 100V and when the voltage is unstable; In contrast, ion-conductive rubber is greatly affected by changes in environmental conditions during preparation, and both kneading temperature and time will greatly affect the resistance of the prepared rubber, and more influencing factors improve the resistance of rubber with specific resistivity. It is difficult to prepare, and the rubber is difficult to guarantee excellent ozone resistance and recovery rate, but at the same time, ion conductive rubber can still maintain stable resistivity under large voltage changes

technical field [0001] The invention relates to the field of macromolecules, in particular to an ion-conducting rubber and a preparation method thereof. The ion-conducting rubber has stable resistivity, is less affected by voltage changes, has excellent ozone resistance, and has a high recovery rate. Background technique [0002] In the operation of an image forming device (such as an electrostatic copier, laser printer, etc.) using the electrostatic copying method, the photosensitive body (such as a toner cartridge) with photoconductivity is first charged to make the surface have a uniform charge, and then accept Exposure forms an electrostatic latent image corresponding to the original image, and then the electrostatic latent image selectively absorbs toner at corresponding positions by electrostatic adsorption to form a toner image (development), and then the toner image is transferred to the copy medium (copy paper) and fix to complete the copying process. [0003] In t...
