Description
(1), technical field
The present invention relates to a kind of preparation method of positive charge organic optical drum of individual layer.
(2), background technology
Since nineteen thirty has invented with the dry method eletrophotography of anthracene as light-guide material for the card Ademilson [USPatent 2,221,776 (1940)], light-guide material has obtained huge development as information-recording material.Current fast development of information technology, office automation almost spreads to the every field of social life, and as the organic light guide drum of laser printing, Xerox core component, its market demand is also increasing.Therefore, organic light guide drum and the organic light-guide material that constitutes it also more and more are subjected to people's attention.The organic light guide drum of laser printing, Xerox core component (OPC), briefly, on electric conductivity is aluminium base, apply the photoconductive material layer exactly, its principle of work is: organic light guide drum in the dark is an insulator, can make its surface reach certain potentials (practicality requires 600-800V, plus or minus) by corona charging or contact charging; When the light (as 780nm laser) with suitable wavelength shines, it is right that the photoelectric material layer produces positive and negative charge, and to the surface, neutralization is the plus or minus on surface originally with the negative or positive charge transfer, the electric charge of illumination part does not keep, and so just forms electrostatic latent image on the organic light guide drum surface; Through charged toner develop, transfer printing ink powder picture and text to paper, the hot pressing photographic fixing, finish printing interval one time.So go round and begin again, laser printer carries out work continuously.Therefore, organic light guide drum can be divided into positive charge organic optical drum and negative charge organic optical drum on principle of work; The number of plies according to photoelectric material from the production method of device can be divided into single layer device and function divergence type multilayer device again.Though positive charge organic optical drum and negative charge organic optical drum have all obtained application in practice, but because the maturity of the manufacture craft of negative charge organic optical drum and materials used is relative higher, its application is more more general than positive charge organic optical drum, in the market mainly based on negative charging property, sandwich construction organic light guide drum.But multilayer device is in the process of making, owing to will be applied to different functional layers on the aluminium drum base step by step, and organic light guide drum is very high to the thickness and the uniformity requirement of each layer, otherwise will have a strong impact on the performance of photoconductor drum, this makes with single layer device and compares, and has that technology is numerous and diverse, make efficiency is low, the difficult control of yield rate, the more high deficiency of cost.Simultaneously, along with the raising of environmental consciousness, the idea of green office more and more is subjected to everybody approval.Therefore, the negative charge organic optical drum problem that produces ozone pollution in application process is also paid close attention to by people day by day.
(3), summary of the invention:
In order to overcome the shortcoming of prior art; the invention provides a kind of preparation method of positive charge organic optical drum; organic light guide drum with this method making; can satisfy the printing requirement of positive charging characteristic laser printer; overcome the numerous and diverse problem of function divergence type sandwich construction device making technics; can also overcome the problem of print procedure ozone pollution, help environmental protection and user's health.
The present invention solves the technical scheme that its technical matters takes: processing step is: (1), use that polycarbonate is dissolved in alkyl chloride, organic solvent of ketone is formed into film solution; (2), with film forming agent solution, metal phthalocyanine and diphenoquinone in mass ratio 1: 40: 4000-1: 100: 8000 ratio is mixed; (3), disperse to make coating fluid; (4), coating fluid is coated on anodised aluminium drum base, promptly form positive charge organic optical drum after the drying.
Described alkyl chloride is 1, the 2-ethylene dichloride; Ketone is cyclohexanone; Film forming agent is polycarbonate (PCZ-300), and the quality of film forming agent solution is 5-10% than concentration; Metal phthalocyanine is a Y-type titanyl phthalocyanine; Quinone is 2,5,7,10-tetra-tert diphenoquinone.
The organic light guide drum that the present invention makes; can satisfy the printing requirement of positive charging characteristic laser printer; overcome the numerous and diverse problem of function divergence type sandwich construction device making technics, can also overcome the problem of print procedure ozone pollution, help environmental protection and user's health.
