Description
Technical field
The present invention relates to a kind of paintings of the photosensitive drums of organic photo conductor drum material and coating technology field, in particular to UV photocuring
Material formula.
Background technique
Organic photo conductor drum (i.e. organic photoconductor OPC) is that one kind can make light generation carrier be formed and be moved under laser irradiation
The novel high-tech information processing device moved, is laser printer, digital duplicating machine, laser facsimile and all-in-one multifunctional machine etc.
The photoelectric conversion and image-forming block of core the most in modern office equipment such as directly determines printing, duplicates at the quality of image transmissions.
It is highly integrated, high added value the organic optoelectronic information products for integrating modern functions material, modern advanced manufacturing technique.
Organic photo conductor drum imaging technique originates from the U.S. and Japan, comprising new material, light, electricity, is mechanically integrated system, advanced
Multiple high-technology fields such as technology and control, are a highly integrated the advanced manufacturing industry with high-tech content.Printer
Fabulous popularization and development is obtained in Japan with duplicator technical, predominantly Japan is monopolized always for a long time.20 generation
The production of the last organic photo conductor drum of discipline just sets up factory and incoming China in China with Japanese enterprises, is then slowly taken seriously.
With the development of printer copier technology, flying print is more more and more universal.And flying print and long-life are to organic photo conductor drum
Requirement it is also higher and higher, quick photoelectric conversion efficiency steady in a long-term, thinner carbon dust is using exporting higher resolution ratio
Image and longer service life.
Current existing photosensitive drums coating technology be using polyphosphazene polymer carbonate resin as matrix resin, it is molten in coating
Enter other functional materials (such as HTM, ETM etc.) and be coated in drying and forming-film on aluminum pipe substrate, resin and functional material do not have friendship
Connection property, hardness and wearability depend on the content of polycarbonate resin structure and molecular weight and functional material in the coating
(small-molecular-weight functional material content is bigger, and wearability is poorer, and content is small, and performance does not reach requirement), positive charging general at present
The service life of type photosensitive drums is rarely found more than 100,000 in ten thousand Zhang Yinliang of 2-5, is mainly produced by Kyocera.Such as text
The copolymerization carbonate resin in EP1424600 is offered, the reports such as polycarbonate resin of specific structure have advanced in JP2017-223896
The new polycarbonate resin of super abrasive characteristic or polyester resin be in resins synthesis by being added in straight chain constitutional repeating unit
Specific abrasion-proof structure unit modification forms, and such technology is concentrated mainly in the original-pack manufacturer's hand of Japan, and associated resin is not external
Public offering, it is high that research and development synthesize similar modified polycarbonate resin cost.
Organic photo conductor drum material of the present invention and coating technology, state-of-the-art to be concentrated mainly on several families, Japan main
In laser printer duplicator manufacturer hand, as core component, manufacturer carries out respective material and coating technology
Effective patent protection and technology blockage.Pass through the patent document of practical organic photo conductor drum product and distribution to each giant manufacturer
The study found that for extend photosensitive drums service life used by new technology direction, mainly concentrate the following aspects, 1. pairs
The synthesis modification of outermost layer coating polycarbonate resin；2. wear-resistant material is added in the coating, such as PTFE, silicone powder, inorganic gold
Belong to powder etc.；3. additional protective layer.But there are certain disadvantages for the above several method: method 1. passes through to matrix resin synthesis modification
Increase photosensitive drums cost to increase coating abrasion performance, sintetics is only by Japanese Ji Jia great factory (such as Mitsubishi Chemical goes out the emerging production of light)
Cooperate the production of photosensitive drums manufacturer, exclusive supply is not for sale；2. wear-resistant material of method is difficult long-term uniformly steady in coating
Fixed dispersion, even if doing special surface processing, technique is also complex, and the wear-resistant material in coating is to the electrical characteristics shadow of photosensitive drums
Sound is larger；Method 3, increasing external protection can effectively enhance the wearability extension photosensitive drums service life, but must increase by one in production process
Road film formation process, thus increase equipment cost and production cycle, furthermore, external protection formula rate and thicknesses of layers must match very well
Light combination sensitive layer can be only achieved synchronous carrier transport rate, have in control more highly difficult.
Summary of the invention
