Abstract
The invention provides a novel charge roller membrane sleeve which is prepared by mixing fluororubber and acrylic ester elastomer containing ether group. The mixing material of the fluororubber and the acrylic ester elastomer containing the ether group has high-low temperature resistance, high elasticity, aging resistance, corrosion resistance and the like. The charge roller membrane sleeve prepared by the material has certain stability, so as to eliminate or reduce effect of environment factors on a quality of printed products. Under the protection of the charge roller membrane sleeve, a charge roller has wear-resisting, aging-resisting performances, is safe and reliable and can charge a photosensitive drum uniformly.
Description
Technical field
The present invention relates to a kind of charging roller Membrane cover, belong to the preparing technical field of electrostatic latent image device with charging roller.
Background technology
The conductivity of charging roller directly produces significant effects to printing effect.Guarantee that print quality just need make charging roller have fabulous charging effect, make photosensitive drums can in specific time, make the photoconductor drum surface have density suitably, be evenly distributed, static charge that polarity is correct.Owing to be to form outside charging roller is metal-cored by conductive rubber or cavernous body parcel, so charging roller can absorb under different humidity and temperature or volatilization moisture, this has just influenced the charging roller carried charge, changes the size of charging roller resistance, make photoconductor drum be subjected to electricity uneven, thereby the print quality problem occurs.
The producer that produces at present the charging roller Membrane cover adopts terpolymer EP rubber or paracril preparation, and this material resistant of high or low temperature is poor, and is not corrosion-resistant, can not well play provide protection to the foam conductive layer by the charging roller Membrane cover of this material preparation.
Summary of the invention:
At the shortcoming of prior art, it is good to the invention provides a kind of high-low temperature resistant, snappiness, ageing-resistant, corrosion resistant charging roller Membrane cover material.
Viton (FKM) has outstanding high temperature resistant, oil resistant, and resistance to chemical attack, performance such as ageing-resistant, but it is low to exist elasticity, the weakness of resistance to low temperature difference.Acrylate elastomer has heat-resisting, and oil resistant is ageing-resistant, and wherein the acrylate elastomer of ether-containing group has more significant resistance to low temperature.The intermingling material of the acrylate of viton (FKM) and ether-containing group has both both advantages simultaneously, is that a kind of high-low temperature resistant is good, snappiness, ageing-resistant, the material of excellent anti-corrosion performance.
A kind of New-type charge roller Membrane cover is made by the acrylate elastomer intermingling material of viton and ether-containing group, by passing through extruder for shaping after the intermingling material sulfuration.
A kind of New-type charge roller of the present invention Membrane cover is prepared by following technical solution:
The acrylic elastomer of viton and ether-containing group carries out blend with 90/10～60/40 ratio, and adding rubber processing aids, 3# vulcanizing agent and mass parts are 2%～6% graphitized carbon black blend, to fully disperseing.Under 170 ℃ of conditions, vulcanize 20min, cooling granulation then.The blend pellet passes through extruder for shaping.
The beneficial effect of this New-type charge roller Membrane cover is to make charging roller have excellent ageing-resistant performance and physical and mechanical properties, and resistance is even, does not have to ooze out phenomenon, and resistant of high or low temperature is good.This charging roller Membrane cover plays a protective role to charging roller foam conductive layer, make charging roller with environmental change (changing) such as temperature and humidity stable in properties; The required charging voltage of charging roller reaches minimum, charge even, stable performance, and can not cause damage to photosensitive drums.Charging roller thereby obtain than the long life image effect that print procedure is obtained.
