Obtained organic photoconductor.
Background technology
The organic photoconductor used in the market in high-speed color digital-code laser composite integrated machine（OPC）Generally use work(
The sandwich construction of energy divergence type, i.e., coat electric charge barrier layer successively on electric conductivity aluminum pipe base（UCL）, charge generation layer（CGL）、
Charge transport layer（CTL）.The coating of each layer is typically dissolved or dispersed in containing film-forming resin by corresponding function material（Or film forming
Agent, Binder）Solution in constitute, coating can using dip-coating, spraying or blade coating etc. mode, then be dried to film layer.
Organic photoconductor is a kind of consumptive material, and its service life is mainly declined by materials chemistry stability, the function of electrogen
The big factor of mechanical property three of lapse rate and coating layer is determined.Study and the result of practical application all shows, the mechanics of coating layer
Property is organic photoconductor " life-span short slab "；In other words, the life-span of organic photoconductor depends on CTL mechanical resistant abrasion
Property.Because：In the course of the work, organic photoconductor constantly rotates at a high speed high-speed color digital-code laser composite integrated machine, its electricity
There is rubbing action in the surface of lotus transport layer, the charge transport layer can be gradually worn out with multiple assembly or medium.This mechanicalness
Abrasion reaches the photoelectric properties that will deteriorate optical conductor to a certain degree, and such as charging potential declines, the increase of dark-decay speed, and influence
Surface nature, such as finish are deteriorated, are detained toner, cause to produce serious Printing Problem.
For this problem, the main method taken at present mainly has：（1）As disclosed in Chinese patent CN102998916B
CTL coating fluid formulas in add lubricant（Such as silicone oil）Or strong film（Such as nano silicon oxide）；（2）Outside charge transport layer
Side is coated one layer of wearability resin（Such as silicones）.The（1）The method of kind is simple to operation but needs are especially careful, because
The poor compatibility of silicone oil or silica etc. and film-forming resin, improper use does not reach effect not only, can deteriorate the light of device on the contrary
Electrical property；The（2）The method of kind complicates the manufacturing process of organic photoconductor, and adds the manufacturing cost of product.
Existing organic photoconductor coating prepare when technique it is cumbersome, these coating or be difficult in process of production protect
Deposit, the problem of influences such as sedimentation, crystallization, solidification are used easily occur；Or the original materialization of coating in existing process for preparation
Characteristic is corrupted such that the coating after use loses due photoelectric properties.
