一种导电发泡橡胶充电辊及其制备方法
摘要：
本发明公开了一种导电发泡橡胶充电辊及其制备方法，所述导电发泡橡胶充电辊包括一金属轴心、发泡管层和套附于发泡管层之外的导电橡胶管层；所述的发泡管层为混有导电炭黑的丁晴橡胶，所述导电炭黑与丁晴橡胶的重量份数比为1.2～2∶100；所述的导电橡胶管层为混有导电炭黑的三元乙胶橡胶，所述导电炭黑与三元乙胶橡胶的重量份分数比为8～15∶100。本发明解决了气候温度对充电辊的影响，因为有海绵弹性层，亦解决了打印过程中出现异响的问题，且不会污染感光鼓，同时，打印寿命能提高一至两个周期，更加有利于环保。
摘要（英）：

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 ratioof 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.
