【発明の詳細な説明】 〈産業上の利用分野〉 この発明は液晶部品用洗浄組成物に関する。[Detailed description of the invention] <Industrial application field> This invention relates to a cleaning composition for liquid crystal parts.

音波によるダメージを与えてしまうおそれもあった。<Conventional technology and its issues> Conventionally, organic solvents such as chlorofluorocarbons, trichloroethane, and fluorocarbons have been used to clean dirt from oils, fats, and resins adhering to liquid crystal parts, but these solvents have a particularly weak ability to dissolve resins, so they are difficult to clean. The aim was to improve the cleaning effect by using ultrasonic waves. Therefore, the cleaning process is troublesome and, in some cases, there is a risk that the liquid crystal components may be damaged by the ultrasonic waves.
更に、前記の如き有機溶剤は安全衛生上或いは安全管理

In particular, fluorocarbons and trichloroethane are said to be substances that cause depletion of the earth's ozone layer, and their use in large quantities is being regulated by international agreements, so their use will virtually no longer be possible.
この発明はこのような従来の技術に着目してなされたも

非毒性で環境に悪影響を及ぼさない液晶部品用洗浄組成
物を提供せんとするものである。The present invention has been made by focusing on such conventional technology, and aims to provide a cleaning composition for liquid crystal parts that is highly effective in cleaning without using ultrasonic waves, is non-toxic, and does not have a negative impact on the environment. That is.

上記の目的を達成するため、この発明に係る液晶部品用
洗浄組成物はテルペン化合物と、必要により４０ｗｔ％
以下の界面活性剤とを含む構成とした。Means for Solving the Problems> In order to achieve the above object, the cleaning composition for liquid crystal parts according to the present invention contains a terpene compound and, if necessary, 40 wt%.
It was configured to include the following surfactants.

のような各種エーテル性油中の天然産品である。These terpene compounds can be used alone and form a complex with the dirt (oils and fats) on the liquid crystal component and are removed after removal by flushing with excess terpene or by adhering to paper or cloth. . However, terpenes are not flushed directly with water because they are almost completely water-insoluble. Alternatively and preferably, the terpene compound is combined with one or more terpene emulsifying surfactants. The addition of such surfactants facilitates the removal of terpenes from the liquid crystal component because upon rinsing with water, the terpenes form an oil-in-water emulsion. This terpene compound is non-toxic and biodegradable to the environment, unlike conventionally used organic solvents. Limonene is a natural product found in various ethereal oils such as lemon, orange, caraway, dill and bergamot oils, which have a pleasant lemon odor.

In particular, such as, but not limited to, linear alkyl benzene sulfonates, linear or branched alcohol ethoxylates and ethoxy sulfates, polysorbate esters, ethoxylated alkyl phenols, and alkyl and dialkyl succinate compounds, Those that can emulsify terpenes can also be used. One example of the latter compound is sodium dioctyl sulfosuccinate. Ethoxylated alkylphenols contain various alkyl side chains and multiple linked ethylene oxide units. Useful compounds of this class contain about 5 to 20, preferably 7 or 8 ethylene oxide groups.
更に、この洗浄組成物は加温する必要がなく、常温（１
５〜２５°Ｃ）で使用することができる。Furthermore, this cleaning composition does not need to be heated and can be kept at room temperature (1
5-25°C).
