Abstract

The invention discloses a conductive foam rubber charging roller and a preparation method thereof. The conductive foam rubber charging roller comprises a metal shaft center, a foaming pipe layer and a conductive rubber hose layer which is sleeved outside the foaming pipe layer, wherein the foaming pipe layer is prepared by nitrile rubber buna (NRB) with conductive black, and the weight part ratio of the conductive black to the NRB is 1.2-2:100; and the conductive rubber hose layer is prepared by ternary B glue rubber with conductive black, and the weight part ratio of the conductive black to the ternary B glue rubber is 8-15:100. In the invention, the influence of climatic temperature on the charging roller is solved; due to the existence of an elastic sponge layer, abnormal sound in the printing process is avoided and a photosensitive drum is not polluted; at the same time, printing life can be improved by one to two periods, thus further being beneficial for environmental protection.

Description

technical field [0001] The invention belongs to the technical field of electrostatic latent phase equipment, and in particular relates to a foamed rubber electric rubber charging roller which can be widely used in printers, copiers and facsimile machines and a manufacturing method thereof. Background technique [0002] At present, the existing technology is generally nylon sleeve or PU sleeve. The defect is that its material will change with the change of temperature, resulting in bottom dust and pitting in printing; there will be abnormal noise during printing, commonly known as "noise", and The stain-resistant drum takes a shorter time. Contents of the invention [0003] One of the objectives of the present invention is to provide a foamed rubber charging roller that can be widely used in printers, copiers and facsimile machines, so as to solve the defects in the prior art. [0004] To achieve the above object, the present invention adopts the following technical soluti...
