200307747 玖'遽_說_ (發明說明應敘#:發明所屬之技術領域、先前技術、內容、實施方式及圖式簡 單說明） 發明所屬之枝術領域 本發明是有關於一種用來淸洗液晶面板的水性液態淸 洗劑組成物。 先前技術 、 液晶面板原本即具有耗電量低的優點，再加上近年來 在高對比化等技術方面有長足進展，故已用來顯示多種影 像。舉例來說，在電腦終端顯示器、電視螢幕及手機等產 品的小型面板等廣泛的領域中，其應用皆甚爲常見。 在典型的液晶面板製程中，係令兩片玻璃基板相距 10//m以下的預定距離，並以接著劑黏合兩片基板，使其 中形成一中空部分，然後將液晶材料封入此中空部分內。 上述兩片玻璃基板內部設置有顯示文字及影像用的電極， 其係由透明導電薄膜所構成，而在其上施加控制用電訊號 時，即可控制文字及影像之顯示。 在上述液晶面板的製程中，兩片基板的接著部分的外 側難免會留下微米級的小寬度，而無法避免地產生一個空 隙。因此，將液晶材料注入兩片玻璃基板間之中空部分時’ 液晶材料會因毛細作用而侵入此空隙中。由於大氣中的污 染物會溶解在空隙內的液晶材料中，而這些空隙恰好位在 施加電訊號給透明電極，而以高密度配置的各自絕緣的電 極端子所在之處，所以會造成絕緣性劣化的問題。因此， 10959pif.doc/008 6 200307747 侵入空隙中的液晶材料必須洗淨除去。 然而，由於空隙處的基板間隔在i〇/im以下，非常狹 窄，所以如欲完全除去侵入的液晶材料，所使用的淸洗劑 必須具有高度的洗淨能力。在習知可用於此的淸洗劑中， 效果較佳者爲氟氯院（Flon)、三氯乙院、三氯乙烯、四氯 乙烯及二氯甲烷等含氯有機溶劑。但是，由於含氯有機溶 劑的管制是世界環保方案中很重要的一環，所以在使用上 大爲受限。 爲此，在發展代用淸洗劑的高度需求下，一些可代替 前述含氯有機溶劑的新型淸洗劑已被開發出來，其係爲碳 氫化合物類的溶劑，或是碳氫化合物溶劑與乙二醇醚的混 合組成物，如日本專利申請案早期公開公報第平10-25495 號所述者。然而，由於此種淸洗劑的可燃性高，故處理上 頗爲困難。 另外，隨著近年來液晶面板的高密度化技術的進展， 前述空隙的間距又更加狹窄，再加上又有提升產能的需 求，所以淸洗劑必須具有可在短時間內洗淨液晶面板的高 度洗淨能力。再者，爲提高液晶面板的生產良率，不僅是 侵入空隙部分的液晶材料，該淸洗劑還必須具備洗淨電極 端子表面之異物的能力。 詳言之，在液晶面板的製程中，通常必須將母材玻璃 切割成大塊的玻璃基板，而在切割過程中會產生大量的粉 末(下文通稱玻璃粉(cullet))，其將附著在電極端子的表面， 而大爲妨礙其後的封裝製程，所以必須洗淨除去。 10959pif.doc/008 7 200307747 玻璃粉之類的表面異物通常僅以分子間作用力附著在 液晶面板上，但也有可能以液晶材料作結合劑，而緊密地 附著在液晶面板上，因此可除去表面異物的淸洗劑必須具 有更高的洗淨力。這種玻璃粉用的淸洗劑例如是日本專利 申請案早期公開公報第平5-271699號、第平7-305093號 及第2001-181699號所述者。然而，其所使用之鹼性清洗 劑不但有破壞液晶面板之虞，且完全沒有洗淨液晶材料的 效果，所以難以除去以液晶材料作結合劑而緊密附著在液 晶面板上的玻璃粉。 如上所述，至今還沒有一種對環境造成的負擔及毒性 小、可燃性低，且可同時洗淨侵入空隙部之液晶材料及液 晶面板電極端子表面上之異物的高洗淨力液晶面板用清洗 劑。 另一方面，近年來爲因應個人電腦、手機與PDA等 的顯示品質要求，彩色液晶面板的需求急速地增加。因此， 除了習知用於被動式面板的超扭轉陣列型（STN)液晶材料 之外，用於主動式面板的薄膜電晶體（TFT)用液晶材料也 有發展。現用之STN液晶材料係爲具有以氰基(cyan〇 gr〇up) 爲代表之取代基的芳香族化合物，而TFT液晶材料係爲具 有以氟原子爲代表之取代基的芳香族化合物。 由於STN液晶材料與TFT液晶材料的分子結構與物 性相異，所以必須使用不同的淸洗劑加以淸洗。詳言之， STN液晶材料可以前述碳氫化合物類的溶劑，或是碳氫化 合物溶劑與乙一醇醚的混合組成物有效地洗淨， 但TFT液 10959pifdoc/008 8 200307747 晶材料則不行，而必須使用不同的淸洗劑來淸洗。 然而’現今爲提高液晶面板的生產力，可適用於分子 結構及物性相異之多種液晶材料的多樣型洗淨組成物當有 其需求。不過，至今爲止，還沒有一種具有可有效洗淨多 種液晶材料的良好洗淨力，且對環境造成的負擔及毒性 小、可燃性又低的淸洗劑組成物。 發明內容 有鑑於此，本發明目的之一爲提出一種液晶面板用水 个生'液態淸洗劑組成物，其可有效地除去侵入液晶面板之空 P集的'液晶材料，以及玻璃粉等附著在液晶面板之電極端子 $面的異物’同時對環境造成的負擔及毒性小，可燃性也 低^本發明之另一目的爲提出一種液晶面板用水性液態淸 '冼劑組成物’其可有效除去因分子結構差異而導致物性不 同的多種液晶材料。 爲達成上述目的，發明人在深入硏究之後發現，含有 下述成分的淸洗劑組成物可以有效地除去侵入液晶面板之 液晶材料，同時對玻璃粉等附著在基板表面的異物 也有頗高的浸透能力，而可有效去除之。該些成分包括具 有支鏈的特定非離子界面活性劑、特定的乙二醇醚化合物 以及碳氫化合物。同時，含有碳氫化合物、特定的乙二醇 醚、陰離子界面活性劑及二甲亞楓(DMSO)的淸洗劑組成 物，其洗淨力不因STN液晶材料及TFT液晶材料之物性 差異而有明顯變化，故可有效去除此二者。上述淸洗劑組 10959pif.doc/008 9 200307747 成物即是本發明的內容。 詳言之’本發明提出以下數種液晶面板用水性液態淸 洗劑組成物： 其一包括成分(A)、（B)、（C)及(D)，以及特定量的水， 其中 成分(A)爲通式（1)所示之化合物，含量爲5〜60wt% : RR^HiCH^^CAO)^ ， (1) 其中R及R1爲碳數1〜8的烷基，且當n=l時，R及R1的 碳數總和小於等於9 ;當n=2時，R及R1的碳數總和小於 等於8;n爲1或2, AO爲碳數2〜4的氧化烯基 (oxyalkylene)，且 m 爲 2〜10 ;

In the prior art, the liquid crystal panel originally has the advantage of low power consumption. In addition, in recent years, there has been considerable progress in high contrast and other technologies, so it has been used to display a variety of images. For example, it is very common in a wide range of fields, such as computer terminal displays, television screens, and small panels for mobile phones. In a typical liquid crystal panel manufacturing process, two glass substrates are placed at a predetermined distance of 10 // m or less, and the two substrates are bonded with an adhesive to form a hollow portion therein, and then a liquid crystal material is sealed in the hollow portion. The two glass substrates are provided with electrodes for displaying characters and images, which are composed of transparent conductive films. When a control signal is applied to the electrodes, the display of characters and images can be controlled. In the above-mentioned manufacturing process of the liquid crystal panel, a small width of micrometer order is inevitably left on the outside of the bonding portion of the two substrates, and a gap cannot be avoided. Therefore, when a liquid crystal material is injected into a hollow portion between two glass substrates, the liquid crystal material penetrates into the space due to capillary action. Pollutants in the atmosphere will dissolve in the liquid crystal material in the gaps, and these gaps are located exactly where the electric signals are applied to the transparent electrodes, and the insulated electrode terminals arranged in high density are located, so the insulation deteriorates. The problem. Therefore, 10959pif.doc / 008 6 200307747 liquid crystal materials that have penetrated into the voids must be cleaned and removed. However, since the substrate interval in the gap is very narrow below i0 / im, the cleaning agent used must have a high cleaning ability to completely remove the invading liquid crystal material. Among the conventional lotions that can be used for this purpose, those with better effects are chlorine-containing organic solvents such as Flon, Trichloroethane, Trichloroethylene, Tetrachloroethylene, and Dichloromethane. However, since the regulation of chlorine-containing organic solvents is an important part of the world's environmental protection programs, its use is greatly restricted. For this reason, under the high demand for the development of alternative lotions, some new lotions that can replace the aforementioned chlorine-containing organic solvents have been developed, which are hydrocarbon solvents, or hydrocarbon solvents and ethyl alcohol. A mixed composition of glycol ethers is described in Japanese Patent Application Laid-Open Publication No. Hei 10-25495. However, since such a cleaning agent is highly flammable, it is difficult to handle. In addition, with the development of high-density technology of liquid crystal panels in recent years, the gaps of the aforementioned gaps have become narrower. In addition, there is a need to increase production capacity. Therefore, the cleaning agent must be capable of cleaning the liquid crystal panel in a short time. Highly washable. Furthermore, in order to improve the production yield of the liquid crystal panel, not only the liquid crystal material invading the void portion, but also the cleaning agent must have the ability to clean the foreign matters on the electrode terminal surface. In detail, in the manufacturing process of the liquid crystal panel, the base material glass must usually be cut into a large glass substrate, and a large amount of powder (hereinafter referred to as a glass powder (cullet)) will be generated during the cutting process, which will adhere to the electrode The surface of the terminal greatly hinders the subsequent packaging process, so it must be cleaned and removed. 10959pif.doc / 008 7 200307747 Surface foreign matter such as glass powder usually adheres to the liquid crystal panel only by intermolecular force, but it is also possible to use the liquid crystal material as a binding agent to adhere tightly to the liquid crystal panel, so the surface can be removed Detergents for foreign bodies must have higher detergency. Such cleaning agents for glass frit are described in, for example, Japanese Patent Application Laid-Open Publication Nos. Hei 5-271699, Hei 7-305093, and 2001-181699. However, the alkaline cleaning agent used may not only damage the liquid crystal panel, but also has no effect of cleaning the liquid crystal material. Therefore, it is difficult to remove the glass frit that adheres closely to the liquid crystal panel with the liquid crystal material as a binder. As described above, there has not been a high-cleaning liquid crystal panel for cleaning the liquid crystal material that has a small burden on the environment, low toxicity, and low flammability, and can simultaneously clean foreign materials invading the gap and liquid crystal panel electrode terminals. Agent. On the other hand, in recent years, in response to display quality requirements of personal computers, mobile phones, and PDAs, the demand for color liquid crystal panels has increased rapidly. Therefore, in addition to conventional super-twisted array (STN) liquid crystal materials for passive panels, liquid crystal materials for thin film transistor (TFT) for active panels have also been developed. The STN liquid crystal material currently used is an aromatic compound having a substituent represented by cyano grup, and the TFT liquid crystal material is an aromatic compound having a substituent represented by a fluorine atom. Since the molecular structure and physical properties of STN liquid crystal materials and TFT liquid crystal materials are different, different cleaning agents must be used for cleaning. In detail, the STN liquid crystal material can be effectively cleaned by the aforementioned hydrocarbon solvents, or a mixed composition of a hydrocarbon solvent and a glycol ether, but the TFT liquid 10959pifdoc / 008 8 200307747 crystal material cannot, and must be cleaned. Use different detergents to rinse. However, in order to improve the productivity of liquid crystal panels, various cleaning compositions that can be applied to a variety of liquid crystal materials with different molecular structures and physical properties should be required. However, until now, there has not been a detergent composition which has a good detergency which can effectively clean a variety of liquid crystal materials, has a small burden on the environment and toxicity, and has a low flammability. SUMMARY OF THE INVENTION In view of this, one of the objectives of the present invention is to propose a liquid liquid detergent composition for liquid crystal panels, which can effectively remove the liquid crystal materials that invade the empty P set of liquid crystal panels, as well as glass powder and the like. The foreign matter on the electrode terminal of the liquid crystal panel is also less burdensome to the environment and less toxic, and has low flammability. Another object of the present invention is to propose an aqueous liquid 淸 'liquid composition' for liquid crystal panels, which can be effectively removed. A variety of liquid crystal materials with different physical properties due to molecular structure differences. In order to achieve the above object, the inventors found after deep research that the detergent composition containing the following components can effectively remove the liquid crystal material penetrating into the liquid crystal panel, and at the same time, foreign substances adhered to the substrate surface such as glass frit are quite high. Penetrating ability, which can be effectively removed. These ingredients include specific non-ionic surfactants with branched chains, specific glycol ether compounds, and hydrocarbons. At the same time, the cleaning power of a detergent composition containing a hydrocarbon compound, a specific glycol ether, an anionic surfactant, and dimethyl sulfoxide (DMSO) does not depend on the physical properties of the STN liquid crystal material and the TFT liquid crystal material. There are obvious changes, so they can be effectively removed. The above lotion group 10959pif.doc / 008 9 200307747 is the content of the present invention. In particular, the present invention proposes the following several liquid liquid detergent compositions for liquid crystal panels: one includes components (A), (B), (C), and (D), and a specific amount of water, wherein the component ( A) is a compound represented by the general formula (1), the content is 5 ~ 60wt%: RR ^ HiCH ^^ CAO) ^, (1) wherein R and R1 are alkyl groups having 1 to 8 carbon atoms, and when n = When l, the sum of the carbon numbers of R and R1 is less than or equal to 9; when n = 2, the sum of the carbon numbers of R and R1 is less than or equal to 8; n is 1 or 2, and AO is an oxyalkylene group having 2 to 4 carbons ), And m is 2 to 10; component (B) is a compound represented by the general formula (2), and the content is 1 to 25 wt%: RR1CH (CH2) nO (AO) jH (2) wherein R, R1, η, and The definition of AO is the same as before, and j is 12 ~ 30; component (C) is a compound represented by the general formula (3), and the content is 1 ~ 20wt%: R20 (A0) kR3 (3) where R2 is a carbon number of 1 ~ 6 alkyl group, phenyl or benzyl group, R3 is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, and k is 1 to 5, and the definition of AO is the same as before; and component (D) is a carbon number 8 to 20 hydrocarbons, content 1 to 10 wt% ° The second includes components (A), (D), and (E) and a specific amount of water, where component (A) is (1) The compound shown is 5 to 60% by weight = RRiCH (CH2) nO (AO) mH (1) where R and R1 are alkyl groups having 1 to 8 carbon atoms, and when n = 1 10 10959pif.doc / 008 200307747 total carbon number of R and Rl is less than or equal to 9; when n = 2, total carbon number of R and Ri is less than or equal to 8; η is 1 or 2, AO is oxidation of carbon number 2 to 4 Alkenyl, and m is 2 to 10; the component (D) is a hydrocarbon having 8 to 20 carbons, and the content is 3 to 40 wt%; and the component (E) is an anionic surfactant, and the content is 20 wt%.
