발명의 분야Field of invention

본 발명은 프린터의 토너 카트리지에 사용되는 전자 사진 감광체(organic photo conductor: "OPC") 드럼(drum)에 관한 것이다. 보다 구체적으로, 본 발명은 프린터 인쇄의 좋은 화상(image)을 구현할 수 있도록 고온고습이나 저온저습과 같은 나쁜 기후 환경에서도 안정성을 갖고, 시간이 경과함에 따라 발생하는 화상의 경시 변화가 없으며, 나아가 드럼 표면의 내구성이 향상된 새로운 OPC 드럼 및 그 제조방법에 관한 것이다.The present invention relates to an organic photo conductor ("OPC") drum used in a toner cartridge of a printer. More specifically, the present invention is stable even in a bad climatic environment such as high temperature and high humidity or low temperature and low humidity so that a good image of printer printing can be realized, and there is no change with time of the image occurring with time, and furthermore, the drum The present invention relates to a new OPC drum with improved surface durability and a method of manufacturing the same.

발명의 배경Background of the Invention

OPC 드럼은 프린터에 널리 사용되고 있는 전자 사진 감광체이다. OPC 드럼은 도전성 지지체 상에 전자 사진 감광층을 형성한 것으로서, 통상 알루미늄 파이프 외부 표면에 알루마이트 층을 형성하고, 그 위에 전하 발생층과 전하 수송층을 차례로 형성하여 전하의 이동에 따라 토너 입자를 이동시켜 필요한 내용을 인쇄하게 된다.OPC drums are electrophotographic photosensitive members widely used in printers. An OPC drum is an electrophotographic photosensitive layer formed on a conductive support. An anodite layer is usually formed on an outer surface of an aluminum pipe, and a charge generating layer and a charge transport layer are sequentially formed thereon to move toner particles as the charge moves. Print what you need.

좋은 화상을 갖는 인쇄를 하기 위하여 OPC 드럼은 아주 중요하다. 특히 OPC 드럼의 표면에 형성되는 전하 발생층과 전하 수송층은 인쇄 화상 품질과 직접적인 관련이 있다.OPC drums are very important for printing with good images. In particular, the charge generating layer and the charge transport layer formed on the surface of the OPC drum are directly related to the print image quality.

시간이 경과함에 따라 또는 인쇄량이 많을수록 인쇄 화상 품질은 차츰 저하된다. 따라서 시간이 경과하여도 좋은 인쇄 화상 품질을 유지하고, 가급적 많은 양을 인쇄하여도 좋은 인쇄 화상 품질을 유지하는 것은 OPC 드럼의 영원한 과제라 할 수 있다.As time passes or as the print volume increases, the print image quality gradually decreases. Therefore, it is a permanent task of the OPC drum to maintain a good print image quality even if time passes and to maintain a good print image quality even if a large amount of printing is possible.

또한 OPC 드럼은 환경 변화에 따라 많은 영향을 받는 것으로 나타나고 있다. 예를 들어, 고온고습의 기후나 저온저습의 기후인 경우에, OPC 드럼의 전하 발생층과 전하 수송층이 나쁜 영향을 받고 그 결과 환경변화에 따른 안정성을 향상시키는 것도 인쇄 화상 품질을 위한 연구과제이다. In addition, OPC drums have been shown to be greatly affected by environmental changes. For example, in the case of high temperature and high humidity or low temperature and low humidity climate, the charge generating layer and the charge transport layer of the OPC drum are adversely affected, and as a result, improving the stability due to environmental changes is a research project for print image quality. .

본 발명자들은 상기와 같은 OPC 드럼의 종래 문제점을 해결하고자 새로운 성분의 전하 발생 재료와 전하 수송재료를 개발하고, 이를 이용하여 전하 발생층과 전하 수송층을 형성함으로써 환경 안정성 및 경시 안정성이 우수한 OPC 드럼을 개발하여 특허출원한 바 있다. 본 발명은 그 특허출원의 환경 안정성과 경시 안정성 이 우수한 OPC 드럼을 더 개량하여 드럼 표면의 내구성을 향상시킨 것이다.The present inventors have developed a charge generating material and a charge transporting material of a new component to solve the conventional problems of the OPC drum as described above, and by using this to form a charge generating layer and a charge transporting layer to produce an OPC drum with excellent environmental stability and stability over time Developed and applied for a patent. The present invention further improves the durability of the drum surface by further improving the OPC drum excellent in environmental stability and time-lapse stability of the patent application.

OPC 드럼은 반복하여 사용할 경우 그 표면에 이상현상이 발생하는데, 그 이상현상은 바로 인쇄 품질을 떨어뜨린다. 드럼 표면의 내구성을 향상시키면, 그만큼 드럼을 더 많은 인쇄를 할 수 있고, 회수하여 재활용하는 횟수도 그만큼 많아진다.OPC drums have abnormalities on their surfaces when used repeatedly, which immediately degrades print quality. If the durability of the drum surface is improved, the drum can be printed more, and the number of times of recovery and recycling is increased.

본 발명의 목적은 고온고습이나 저온저습과 같은 기후환경에서도 좋은 인쇄 화상을 구현할 수 있는 우수한 환경 안정성을 갖는 OPC 드럼을 제공하기 위한 것이다.It is an object of the present invention to provide an OPC drum having excellent environmental stability capable of realizing a good print image even in a climatic environment such as high temperature, high humidity or low temperature and low humidity.

본 발명의 다른 목적은 시간이 경과하여도 좋은 인쇄 화상을 구현할 수 있는 우수한 경시 안정성을 갖는 OPC 드럼을 제공하기 위한 것이다.Another object of the present invention is to provide an OPC drum having excellent stability over time capable of realizing a printed image that may pass over time.

본 발명의 또 다른 목적은 환경 안정성과 경시 안정성이 우수한 OPC 드럼을 제조하기 위한 새로운 전하 발생 재료 조성물과 전하 수송 재료 조성물을 제공하기 위한 것이다.Another object of the present invention is to provide a new charge generating material composition and a charge transport material composition for producing an OPC drum with excellent environmental stability and stability over time.

본 발명의 또 다른 목적은 드럼 표면의 내구성을 향상시켜 프린터의 인쇄 매수를 획기적으로 증가시킬 수 있는 새로운 OPC 드럼을 제공하기 위한 것이다.It is another object of the present invention to provide a new OPC drum which can improve the durability of the drum surface and can dramatically increase the number of prints of the printer.

본 발명의 또 다른 목적은 드럼 표면의 내구성을 향상시켜 재활용 횟수를 증가시킬 수 있는 새로운 OPC 드럼을 제공하기 위한 것이다.Another object of the present invention is to provide a new OPC drum which can increase the number of recycling by improving the durability of the drum surface.

발명의 구체예에 대한 상세한 설명Detailed Description of the Invention

OPC 드럼은 도전성 지지체로 알루미늄 파이프를 이용하여 제작된다. 알루미늄 파이프로부터 OPC 드럼을 제작하는 단계는 크게 4 단계로 구분된다. 첫 단계는 알루미늄 파이프 표면을 가공하고, 두 번째 단계는 알루마이트 도금 처리를 하고, 세 번째 단계는 전하 발생 재료(CGM)를 용매에 용해시켜 제조한 전하 발생 재료 액(CGM Liquid: "CGL")으로 코팅하고, 마지막으로 전하 수송 재료(CTM)를 용매에 용해시켜 제조한 전자 수송 재료액(CTM Liguid: "CTL")으로 코팅한다.OPC drums are fabricated using aluminum pipes as conductive supports. The manufacturing of the OPC drum from the aluminum pipe is largely divided into four steps. The first step is to machine the aluminum pipe surface, the second step is to anodize plating, and the third step is CGM Liquid ("CGL") made by dissolving the charge generating material (CGM) in a solvent. Coating, and finally with an electron transport material liquid (CTM Liguid: "CTL") prepared by dissolving the charge transport material (CTM) in a solvent.

첫 단계인 표면 가공 단계는 알루미늄 파이프의 표면을 균일하게 하기 위한 공정으로, 통상 기존의 가공기에서 바이트를 이용하여 처리한다. 일종의 기계적인 세정(polishing) 공정으로 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의하여 용이하게 실시될 수 있다.The first step, the surface machining step, is to make the surface of the aluminum pipe uniform, and is usually processed using a bite in an existing machine. As a kind of mechanical polishing process, it can be easily carried out by those skilled in the art.

두 번째 단계인 알루마이트 도금 처리 공정은 상기 표면처리된 알루미늄 파이프에 알루마이트를 도금하여 알루마이트 층을 형성하는 것으로 강제 산화 아노다이징(anodizing)이라 할 수 있다. 이렇게 알루마이트 도금층을 형성함으로써 난반사 및 다반사를 방지할 수 있다.The second step, the alumite plating process, is to form an alumite layer by plating an alumite on the surface-treated aluminum pipe, which may be referred to as forced oxide anodizing. By forming the alumite plating layer in this way, diffuse reflection and multiple reflection can be prevented.

알루마이트 도금층이 형성되면, 그 위에 전하 발생층을 형성하는 세 번째 단계를 행한다. 종래에는 티타늄 프탈로시아닌 화합물을 전하 발생 재료로 사용한 CGL 조성물을 코팅하여 왔다. 그러나 본 발명에서는 환경 안정성과 경시 안정성을 좋게 하기 위하여 티타늄 프탈로시아닌 화합물에 인듐이 혼합된 인듐계 티타늄 프탈로시아닌 화합물을 전하 발생 재료로 사용한다.When the alumite plating layer is formed, a third step of forming a charge generating layer thereon is performed. Conventionally, a CGL composition using a titanium phthalocyanine compound as a charge generating material has been coated. However, in the present invention, indium-based titanium phthalocyanine compound in which indium is mixed with titanium phthalocyanine compound is used as a charge generating material in order to improve environmental stability and time stability.

본 발명의 전하 발생 재료(charge generation material: "CGM") 조성물은 인듐계 티타늄 프탈로시아닌 화합물 0.5∼5 중량%와 바인더 수지 0.5∼5 중량%를 용매 90∼99 중량%에 용해시켜 제조한다. 인듐계 티타늄 프탈로시아닌 화합물은 70∼99 중량%의 티타늄 프탈로시아닌 화합물과 30∼1 중량%의 인듐으로 이루어진다.The charge generation material ("CGM") composition of the present invention is prepared by dissolving 0.5 to 5% by weight of the indium titanium phthalocyanine compound and 0.5 to 5% by weight of the binder resin in 90 to 99% by weight of the solvent. The indium titanium phthalocyanine compound is composed of 70 to 99 wt% titanium phthalocyanine compound and 30 to 1 wt% indium.

본 발명의 CGL 조성물은 용매로 THF(테트라히드로퓨란)를 사용하고, 바인더 수지로서 폴리비닐 부티랄(polyvinyl butyral: PVB), 폴리비닐 아세탈(polyvinyl acetal: PVA) 또는 이들의 혼합물을 사용한다. The CGL composition of the present invention uses THF (tetrahydrofuran) as a solvent and polyvinyl butyral (PVB), polyvinyl acetal (PVA) or a mixture thereof as a binder resin.

The aluminum pipe on which the alumite plating layer is formed is immersed in the CGL liquid prepared above to form a charge generating layer on the alumite plating layer. The immersed aluminum pipe is allowed to air dry to dry the CGL liquid. Since the solvent used in the CGL liquid is THF, natural drying is possible.

CGL 액이 건조되어 전하 발생층이 형성되면, 그 위에 전하 수송층을 형성시킨다. When the CGL liquid is dried to form a charge generating layer, a charge transport layer is formed thereon.

TPD 화합물은 메타형, 파라형 등이 있는데, 이들은 단독으로 또는 혼합하여 사용할 수 있다. The charge transport material (CTM) composition of the present invention comprises 5 to 12% by weight of a charge transport material composed of a compound having a stilbene skeleton and a TPD compound, 5 to 15% by weight of a binder resin, and 0.001 to 2% by weight of a silane coupling agent. It is prepared by dissolving in 71 to 89.999% by weight of solvent. The compound having the stilbene skeleton is 2 to 5% by weight of the total weight of the charge transport material composition, and the TPD compound is 3 to 7% by weight of the total weight of the charge transport material composition. TPD compounds include metatypes and paratypes, and these may be used alone or in combination.

CTL 용액 조성물을 제조하기 위하여 사용가능한 용매로는 유기용제로서 THF와 톨루엔 혼합물을 사용하는 것이 바람직하다. THF와 톨루엔의 사용비율은 중량비로서 약 75 : 25 ~ 70 : 30 범위로 하는 것이 바람직하다.As a solvent usable for preparing the CTL solution composition, it is preferable to use a mixture of THF and toluene as an organic solvent. The use ratio of THF and toluene is preferably in the range of about 75:25 to 70:30 as weight ratio.

CTL 용액 조성물에 사용되는 바인더 수지로는 폴리카보네이트가 있다. The binder resin used in the CTL solution composition is polycarbonate.

전하 발생층이 형성된 알루미늄 파이프는 위에서 제조된 CTL 액에 침지하여 전하 발생층 위에 전하 수송층을 형성시킨다. 침지되었던 알루미늄 파이프는 약 100~130 ℃ 온도에서 약 10~30 분간 건조시켜 전하 수송층을 형성시킨다. The aluminum pipe on which the charge generation layer is formed is immersed in the CTL liquid prepared above to form a charge transport layer on the charge generation layer. The immersed aluminum pipe is dried at a temperature of about 100 to 130 ° C. for about 10 to 30 minutes to form a charge transport layer.

상기와 같은 조성을 갖는 CML 액과 CTL 액으로 알루마이트 층이 형성된 알루미늄 파이프에 전하 발생층과 전하 수송층을 형성함으로써 고온고습이나 저온저습과 같은 열악한 기후환경에서도 좋은 인쇄 화상을 구현할 수 있고, 시간이 경과하여도 우수한 경시 안정성을 가지며, 우수한 표면 내구성을 갖는 OPC 드럼을 제공할 수 있다. By forming the charge generating layer and the charge transport layer in the aluminum pipe in which the anodized layer is formed of the CML liquid and the CTL liquid having the above composition, it is possible to realize a good print image even in a harsh climatic environment such as high temperature, high humidity or low temperature and low humidity. It is also possible to provide an OPC drum having good time stability and excellent surface durability.

드럼 표면의 내구성이 향상되기 때문에, 종전에는 약 10,000 매 정도 인쇄한 후, 드럼을 교체하였으나, 본 발명에서는 약 20.000매 정도를 인쇄하고 교체하여도 인쇄 품질이 양호하다. 또한 종전의 OPC 드럼은 1∼2 회 정도 재활용을 하는 반면, 본건 특허는 3∼4 회 정도까지 가능하다.Since the durability of the surface of the drum is improved, the drum was replaced after printing about 10,000 sheets, but in the present invention, the printing quality is good even when printing and replacing about 20.000 sheets. In addition, the conventional OPC drum is recycled about 1 to 2 times, while the patent can be about 3 to 4 times.
