Abstract

The invention relates to the technical field of charging rollers and particularly relates to an ECO (Epichlorohydrin) ion-conducting type spongy charging roller and a preparation method thereof. The ECO ion-conducting type spongy charging roller comprises a roller shaft, a foaming-conducting sponge layer sheathed at the outer side of the roller shaft and an ECO ion-conducting rubber layer sheathedat the outer side of the foaming-conducting sponge layer, wherein the foaming-conducting sponge layer is prepared from the following raw materials in parts by weight: 40-60 parts of ethylene-propylene-diene monomer rubber, 20-40 parts of superconducting carbon black, 0.5-1.5 parts of ion conducting agent, 3-7 parts of foaming agent, 4-7 parts of accelerator, 2-6 parts of active agent, 1-2 parts of bridging agent and 2-4 parts of processing aid. The ECO ion-conducting type spongy charging roller is good in conductivity, mechanical property and durability and long in service life.

Description

technical field [0001] The invention relates to the technical field of charging rollers, in particular to an ECO ion-conductive sponge charging roller and a preparation method thereof. Background technique [0002] The charging roller used on the printing equipment is responsible for contacting and rotating the photosensitive drum, so that the photosensitive drum is evenly charged, and the electrostatic latent image after exposure is generated. The existing charging roller has poor conductivity, poor mechanical properties and durability, and short service life. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide an ECO ion-conductive sponge charging roller, which has good electrical conductivity, good mechanical properties, good durability and long service life. [0004] Another object of the present invention is to provide a preparation method of an ECO ion-conductiv...
