【発明の属する技術分野】
本発明は、CD盤、MD盤、光ディスク等の光情報記録媒体、これらの記録あるいは読み出し装置を含む光情報装置におけるレンズ、拡大鏡レンズ、眼鏡レンズ、カメラレンズ等光学機器のレンズ、その他光学インターフェイス、光学機器の鏡面部や一般の化粧鏡等の光沢表面、パソコンの画面、液晶画面、プラスチック製品、建築物の窓ガラスや車両の窓ガラス等のガラス等の透明性のある表面の洗浄に適した洗浄物に関する。
【0002】
【従来の技術】
これまでレンズ、眼鏡レンズ、カメラレンズ、パソコンの画面、液晶画面、プラスチック製品、窓ガラス、ガラス等の透明性のある表面やCD盤、MD盤、光ディスク、鏡等の光沢表面を清浄にする目的で数々の洗浄剤が市販されている。これらのものは透明性が高い又は表面に光沢性があるため油溶性、水溶性の汚れが付着すると目立つ他、使用に支障が生じる原因となる。
【0003】
これを回避するため、種々の洗浄剤が市販されているが、液状タイプ、フォームタイプのものであると使用時に洗浄剤の他に拭き取るティッシュペーパー等の布帛が必ず必要になってくるため簡便性に欠ける。また、洗浄成分である有機溶剤や界面活性剤により汚れを洗浄すると、余剰の洗浄成分が表面に残って拭き残りとなり、これが使用時に支障が出る原因となっている。拭き残りの問題を回避するため、洗浄成分にエタノール、イソプロピルアルコール等の分子量が小さく、揮発性の高い低級アルコールを配合した製品も販売されているが、眼鏡等のレンズは表面がコート処理されており、低級アルコールはこのコート処理剤を剥離させてしまうという問題がある。さらに、洗浄剤が含有されていない、乾燥した布帛で拭くタイプの洗浄物もあるが、汚れの程度が軽度の場合は有効であっても、水溶性、油溶性の目立つ汚れがあるとこのような洗浄物で拭くだけでは充分な洗浄効果が得られないことと、乾燥しているため、清掃時に被洗物との摩擦が大きくなり、被洗物表面を傷をつける恐れがあるという問題がある。
【0004】
【発明が解決しようとする課題】
本発明は、上記従来の技術の欠点に鑑み、CD盤、MD盤、光ディスク等の光情報記録媒体、これらの記録あるいは読み出し装置を含む光情報装置におけるレンズ、拡大鏡レンズ、眼鏡レンズ、カメラレンズ等光学機器のレンズ、その他光学インターフェイス、光学機器の鏡面部や一般の化粧鏡等の光沢表面、パソコンの画面、液晶画面、プラスチック製品、建築物の窓ガラスや車両の窓ガラス等のガラス等の透明性のある表面の汚れを拭き残りなく清浄にすることが出来、また洗浄剤成分により眼鏡等レンズにコート処理されているコート剤の剥離の問題を回避し、洗浄剤と布帛が一体となっているため、簡便に使用することのできる洗浄物を提供することを課題とする。
【0005】
【課題を解決するための手段】
本発明者は、上記課題を解決するために鋭意研究を重ねた結果、低級アルコールを含まない各種有機溶剤、および/又は界面活性剤を極端に低濃度で含有する洗浄剤を布帛に含浸させて使用する事により、十分な洗浄能力があり、更に拭き残りがなく、また眼鏡等の表面コートを剥離させることがなく、簡便に清浄できる洗浄物を見出し、この知見に基づいて本発明をなすに至った。
【0006】
【発明の実施の形態】
以下、本願発明について具体的に説明する。
本願発明の洗浄物は主として、CD盤、MD盤、光ディスク等の光情報記録媒体、これらの記録あるいは読み出し装置を含む光情報装置におけるレンズ、拡大鏡レンズ、眼鏡レンズ、カメラレンズ、等光学機器のレンズ、その他光学インターフェイス、光学機器の鏡面部や一般の化粧鏡等の光沢表面、パソコンの画面、液晶画面、プラスチック製品、建築物の窓ガラスや車両の窓ガラス等のガラス等の透明性のある表面を拭き残りなく清浄にするために用いることが出来る。
さらに、本発明の洗浄物は布帛を用いているため、簡便に使用することができる。
【0007】
本発明の洗浄剤に含まれる有機溶剤としては、水溶性有機溶剤および/又は油溶性有機溶剤を使用することができる。水溶性有機溶剤としてはコート処理された洗浄表面に対してコート剤の剥離を促進することが少なく、水に対して常温で任意に溶解することのできるものである。例として、プルピレングリコール、グリセリン等のポリオール類、エチレングリコールモノプロピルエーテル、エチレングリコールモノブチルエーテル、ジエチレングリコールモノブチルエーテル、ジプロピレングリコールモノメチルエーテル等の水溶性グリコールエーテル類、モノエタノールアミン、ジエタノールアミン、トリエタノールアミン等のアルカノールアミン類、イミダゾール、ピリジン等の含窒素複素環式アミンおよびその誘導体等を挙げることが出来る。
【0008】
油溶性有機溶剤の例としては、例えばパラフィン系炭化水素、ナフテン系炭化水素、オレフィン系炭化水素、芳香族炭化水素等の石油系有機溶剤類、エチレングリコールモノベンジルエーテル、ジエチレングリコールジブチルエーテル、プロピレングリコールモノブチルエーテル、ジプロピレングリコールジメチルエーテル、プロピレングリコールモノフェニルエーテル等の油溶性グリコールエーテル類、大豆油などの脂肪酸トリグリセリド類等を挙げることが出来る。
【0009】
これら有機溶剤は単独でも2種類以上の混合物としても使用することが出来、更に水溶性有機溶剤と油溶性有機溶剤を混合して使用することも出来る。有機溶剤の使用量としては洗浄剤の0.0001〜0.1質量%が好ましく、0.005〜0.05質量%で使用することが特に好ましい。また水溶性有機溶剤と油溶性有機溶剤は水溶性、油溶性の両方の汚れに対応するために混合して使用することが好ましい。水溶性有機溶剤と油溶性有機溶剤を混合して使用する場合は、質量比で9/1〜1/9が好ましく、8/2〜2/8で使用するのが特に好ましい。有機溶剤量が0.1質量%を超えると拭き残りの原因となり、また0.0001質量%未満であると汚れ落ちが不充分な場合が生じる。
【0010】
本発明の洗浄剤に含まれる界面活性剤は洗浄成分としてや被洗物表面への均一の濡れ性向上のために含むことが好ましい。本発明の洗浄剤に含まれる界面活性剤は、単品としても2種類以上の混合物としても使用することが出来る。界面活性剤としてはノニオン系、アニオン系、カチオン系、両性のいずれの界面活性剤であってもよい。
【0011】
ノニオン界面活性剤としては、例えばポリオキシエチレンアルキルエーテル、ポリオキシエチレン脂肪酸エステル、ポリオキシアルキルフェノールエーテル、ソルビタン脂肪酸エステル、ポリオキシエチレンソルビタン脂肪酸エステル、ショ糖脂肪酸エステル、アルキルジメチルアミンオキシドなどが挙げられる。アニオン界面活性剤としては例えばアルキル硫酸塩、ポリオキシエチレンアルキルエーテル硫酸塩、アルキルベンゼンスルフォン酸塩、脂肪酸塩などが挙げられる。カチオン界面活性剤としては例えば、塩化ステアリルトリメチルアンモニウム、塩化ベンザルコニウム、塩化セチルピリジニウムなどが挙げられる。また両性界面活性剤としてはアルキルベタイン、アルキルジエチルエチレントリアミノ酢酸などが挙げられる。これら界面活性剤の中で洗浄性からノニオン系活性剤を使用することが好ましい。また界面活性剤は単独でも2種類以上の混合物としても使用することができる。界面活性剤の使用量としては洗浄剤の0.001〜0.1質量%が好ましく、洗浄性と拭き残りを考慮すると0.005〜0.05質量%で使用することが特に好ましい。
【0012】
防腐剤は、その種類によって必要とする使用量に大きな差があるが、その使用量は洗浄剤の0.1質量%以下におさえることが大切である。防腐剤の使用量が0.1質量%を超えると拭き残りの原因となる。従って、使用し得る防腐剤は、単独で使用する場合は少量でも効果の大きい防腐剤を使用したり、複数の防腐剤の併用により使用量を低減する工夫が必要となる。単独でも使用できる防腐剤の例として、メチルイソチアゾリノン、クロロメチルイソチアゾリノン、ベンズイソチアゾリノン、ブロモニトロプロパンジオール等が挙げられる。
【0013】
本発明の洗浄剤には本発明の目的が阻害されない範囲で必要により、通常洗浄剤に用いられる成分、例えば酸化防止剤、防錆剤、pH調整剤、シリコーンオイル類、フッ素オイル類、香料などを適宜配合してよい。但し、拭き残りを防ぐために、水以外の配合成分の総量は1質量%以内に押さえることが好ましく、更に好ましくは0.5質量%以内である。
【0014】
本発明で使用する布帛とは、特に限定されるものではないが、例えばセルロース繊維である綿、綿リンター、パルプ、ビスコース法レーヨン、銅アンモニア法レーヨン及びそれらを改質したもの等を挙げることが出来る。また疎水性繊維とし、例えばポリエチレン、ポリプロピレン、ポリエステル、アクリル、ナイロン繊維等を挙げることが出来、これらの繊維は単体又は混合物として使用することが出来る。また、布帛の目付量は薄すぎても厚すぎても使用しにくいため、10〜120g/m2 で使用することが好ましく、更には15〜80g/m2で使用することが好ましい。また布帛の繊維径が10μm以下のものが混紡された極細繊維布帛であると、被洗物表面への接点数が多く、密着性が高いことから洗浄力、拭き残りの少なさの点から好ましい。また布帛の中でも特に不織布を使用することが、寸法や目付量等の製造安定性が高いこと、コストの面で優れることから好ましい。この様な布帛の例として、 綿布、亜麻、C1030、GN252、(旭化成(株)社製不織布)、 CO40N/A02(ユニチカ(株)社製不織布)、 RPE5070A(オーミケンシ(株)社製不織布)、AP−50(デュポン(株)製不織布)が挙げられる。
【0015】
本発明の洗浄物は、洗浄剤を布帛に含浸して製造される。洗浄物中の洗浄剤が布帛質量に対して少なすぎると洗浄効果を発揮するほど被洗物表面に洗浄剤を付与することが出来ず、また汚れ分を除去するのに必要な量以上では、拭き残りの原因となることや過剰のためコスト高になるので、洗浄物中の洗浄剤の総量が、布帛質量に対して50〜300質量%含浸されていることが好ましく、80〜200質量%含浸されていることが特に好ましい。
【0016】
本発明の洗浄物は透明性のある表面や光沢表面以外にも、表面を清浄にすることが出来るため、家具や台所周辺、自動車外部および内部、自転車、装飾品、テキスタイル、タイル等の洗浄物として使用することが出来る。

In order to avoid this, various cleaning agents are commercially available. However, in the case of liquid type and foam type, fabrics such as tissue paper to be wiped off in addition to the cleaning agent are always required at the time of use. Lack. Moreover, when dirt is washed with an organic solvent or a surfactant, which is a cleaning component, excess cleaning components remain on the surface and remain unwiped, which causes troubles during use. In order to avoid the problem of unwiping, products with low molecular weight such as ethanol and isopropyl alcohol and highly volatile lower alcohol are also sold as cleaning ingredients, but lenses such as eyeglasses are coated on the surface. In addition, the lower alcohol has a problem that the coating agent is peeled off. In addition, there is a type of cleaning product that does not contain a cleaning agent and is wiped with a dry cloth. Even if it is effective when the degree of dirt is mild, it is effective when there is dirt that is prominent in water and oil solubility. Wiping with a clean object does not provide a sufficient cleaning effect, and because it is dry, there is a problem that the friction with the object to be cleaned increases during cleaning, and the surface of the object to be cleaned may be damaged. is there.
[0004]
[Problems to be solved by the invention]
In view of the above-described drawbacks of the prior art, the present invention provides a lens, a magnifying lens, a spectacle lens, and a camera lens in an optical information device including an optical information recording medium such as a CD disc, an MD disc, and an optical disc, and a recording or reading device thereof. Optical equipment lenses, other optical interfaces, glossy surfaces such as mirror surfaces of optical equipment and general makeup mirrors, personal computer screens, liquid crystal screens, plastic products, glass windows for buildings, vehicle windows, etc. The surface of the transparent surface can be cleaned without wiping, and the problem of peeling off the coating agent coated on the lens such as eyeglasses by the cleaning agent component is avoided, and the cleaning agent and the cloth are integrated. Therefore, it is an object to provide a washed product that can be used easily.
[0005]
[Means for Solving the Problems]
As a result of intensive research in order to solve the above problems, the present inventor impregnated a fabric with various organic solvents not containing a lower alcohol and / or a detergent containing an extremely low concentration of a surfactant. By using it, it has been found that there is a sufficient cleaning ability, there is no wiping residue, and the surface coat such as spectacles is not peeled off and can be easily cleaned, and the present invention is made based on this knowledge. It came.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be specifically described.
The cleaning object of the present invention mainly includes optical information recording media such as CD discs, MD discs, and optical discs, and optical information devices such as lenses, magnifier lenses, spectacle lenses, camera lenses in optical information devices including these recording or reading devices. Transparent surfaces such as lenses, other optical interfaces, glossy surfaces such as mirror surfaces of optical equipment and general makeup mirrors, personal computer screens, liquid crystal screens, plastic products, glass windows for buildings and vehicle windows, etc. It can be used to clean the surface without wiping.
Furthermore, since the washed product of the present invention uses a fabric, it can be used easily.
[0007]
As the organic solvent contained in the cleaning agent of the present invention, a water-soluble organic solvent and / or an oil-soluble organic solvent can be used. As the water-soluble organic solvent, it is less likely to promote the peeling of the coating agent on the coated cleaning surface and can be arbitrarily dissolved in water at room temperature. Examples include polyols such as propylene glycol and glycerin, water-soluble glycol ethers such as ethylene glycol monopropyl ether, ethylene glycol monobutyl ether, diethylene glycol monobutyl ether and dipropylene glycol monomethyl ether, monoethanolamine, diethanolamine and triethanolamine. And alkanolamines, nitrogen-containing heterocyclic amines such as imidazole and pyridine, and derivatives thereof.
[0008]
Examples of oil-soluble organic solvents include petroleum organic solvents such as paraffinic hydrocarbons, naphthenic hydrocarbons, olefinic hydrocarbons, aromatic hydrocarbons, ethylene glycol monobenzyl ether, diethylene glycol dibutyl ether, propylene glycol mono Examples thereof include oil-soluble glycol ethers such as butyl ether, dipropylene glycol dimethyl ether and propylene glycol monophenyl ether, and fatty acid triglycerides such as soybean oil.
[0009]
These organic solvents can be used alone or as a mixture of two or more kinds, and further, a water-soluble organic solvent and an oil-soluble organic solvent can be mixed and used. The amount of the organic solvent used is preferably 0.0001 to 0.1% by mass of the cleaning agent, and particularly preferably 0.005 to 0.05% by mass. The water-soluble organic solvent and the oil-soluble organic solvent are preferably mixed and used in order to cope with both water-soluble and oil-soluble stains. When using a mixture of a water-soluble organic solvent and an oil-soluble organic solvent, the mass ratio is preferably 9/1 to 1/9, particularly preferably 8/2 to 2/8. If the amount of the organic solvent exceeds 0.1% by mass, it may cause wiping residue, and if it is less than 0.0001% by mass, the removal of dirt may be insufficient.
[0010]
The surfactant contained in the cleaning agent of the present invention is preferably included as a cleaning component or for improving the wettability uniformly on the surface of the object to be cleaned. The surfactant contained in the cleaning agent of the present invention can be used as a single product or as a mixture of two or more. The surfactant may be any nonionic, anionic, cationic, or amphoteric surfactant.
[0011]
Examples of the nonionic surfactant include polyoxyethylene alkyl ether, polyoxyethylene fatty acid ester, polyoxyalkylphenol ether, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, sucrose fatty acid ester, alkyldimethylamine oxide and the like. Examples of the anionic surfactant include alkyl sulfates, polyoxyethylene alkyl ether sulfates, alkyl benzene sulfonates, and fatty acid salts. Examples of the cationic surfactant include stearyltrimethylammonium chloride, benzalkonium chloride, cetylpyridinium chloride and the like. Examples of amphoteric surfactants include alkylbetaines and alkyldiethylethylenetriaminoacetic acids. Among these surfactants, it is preferable to use a nonionic surfactant because of its detergency. The surfactant can be used alone or as a mixture of two or more. As the usage-amount of surfactant, 0.001-0.1 mass% of a cleaning agent is preferable, and it is especially preferable to use at 0.005-0.05 mass% when a cleaning property and wiping residue are considered.
[0012]
The amount of antiseptic used varies greatly depending on its type, but it is important to keep the amount used below 0.1% by weight of the detergent. If the amount of the preservative used exceeds 0.1% by mass, it causes wiping residue. Therefore, when the preservatives that can be used are used alone, it is necessary to use a preservative that is highly effective even in a small amount or to reduce the amount of use by using a plurality of preservatives. Examples of preservatives that can be used alone include methyl isothiazolinone, chloromethyl isothiazolinone, benzisothiazolinone, bromonitropropanediol, and the like.
[0013]
The cleaning agent of the present invention is necessary as long as the purpose of the present invention is not hindered, and components usually used in the cleaning agent, such as antioxidants, rust inhibitors, pH adjusters, silicone oils, fluorine oils, fragrances, etc. May be appropriately blended. However, in order to prevent unwiping, the total amount of the ingredients other than water is preferably kept within 1% by mass, and more preferably within 0.5% by mass.
[0014]
The fabric used in the present invention is not particularly limited, but examples thereof include cellulose fibers such as cotton, cotton linter, pulp, viscose rayon, copper ammonia rayon, and modified ones thereof. I can do it. Examples of the hydrophobic fiber include polyethylene, polypropylene, polyester, acrylic, and nylon fiber, and these fibers can be used alone or as a mixture. Further, since the fabric weight is too thin or too thick to be used, it is preferably used at 10 to 120 g / m 2 , more preferably 15 to 80 g / m 2 . Further, an ultrafine fiber fabric in which a fabric fiber diameter of 10 μm or less is blended is preferable from the viewpoint of a large number of contacts to the surface of the object to be washed and high adhesion, from the viewpoint of detergency and a small amount of wiping residue. . Of the fabrics, it is particularly preferable to use a nonwoven fabric because it has high production stability such as dimensions and basis weight, and is excellent in cost. Examples of such fabrics include cotton cloth, flax, C1030, GN252 (nonwoven fabric manufactured by Asahi Kasei Co., Ltd.), CO40N / A02 (nonwoven fabric manufactured by Unitika Ltd.), RPE5070A (nonwoven fabric manufactured by Ohmicenshi Co., Ltd.), AP-50 (nonwoven fabric manufactured by DuPont) can be mentioned.
[0015]
The washed product of the present invention is produced by impregnating a fabric with a cleaning agent. If the amount of the cleaning agent in the cleaning object is too small relative to the fabric mass, the cleaning agent cannot be applied to the surface of the object to be cleaned so that the cleaning effect is exerted, and more than the amount necessary for removing the dirt, Since it becomes a cause of wiping residue and is excessive, and the cost is high, it is preferable that the total amount of the cleaning agent in the cleaning object is impregnated with 50 to 300% by mass with respect to the mass of the fabric, and 80 to 200% by mass. It is particularly preferred that it is impregnated.
[0016]
Since the washed product of the present invention can clean surfaces other than transparent surfaces and glossy surfaces, it can be used to clean furniture, kitchen surroundings, automobile exteriors and interiors, bicycles, ornaments, textiles, tiles, etc. Can be used as
