Description
本発明は、主として電子部品、光学部品のワイピングに用いられるスワブ、即ち棒状物の先端に清拭部が取り付けられた清拭具に関する。 The present invention relates to a swab mainly used for wiping electronic components and optical components, that is, a wiping tool in which a wiping portion is attached to the tip of a rod-like object.
電子部品、光学部品等の製造においては、広い平面部ばかりでなく、狭い特定部分、コーナー部、溝等狭い局部空間のワイピングが必要であり、多種多様なスワブと総称される清拭具が使用されている。 In the manufacture of electronic parts, optical parts, etc., it is necessary to wipe not only wide flat parts but also narrow local spaces such as narrow specific parts, corner parts, grooves, etc., and wiping tools collectively called various swabs are used. Has been.
最も代表的なスワブは綿棒であるが、綿球部に用いられる繊維は太く、ワイピング性能が不足であり、かつワイピング対象を傷つけやすく、また脱落する繊維くずによる自己発塵性、綿球部の成形バインダーであるポリビニルアルコール、酢酸ビニル等の溶出があり、対象を傷つけず拭き残りなく拭くことが出来る優れたワイピング性並びに自らの発塵、溶出物により対象を汚染することのない不汚染性が強く求められる高度なワイピングには不向きであった。 The most typical swab is a cotton swab, but the fibers used in the cotton ball are thick, the wiping performance is insufficient, the object to be wiped is easily damaged, and self-dusting due to fiber scraps falling off. There is elution of molding alcohols such as polyvinyl alcohol and vinyl acetate, and it has excellent wiping ability that can be wiped without damaging the target without damaging the target, and it is non-contaminating that does not pollute the target with its own dust and eluate. It was unsuitable for highly demanding advanced wiping.
綿棒以外にも、ポリエステルニット布、ポリウレタンスポンジ、0.5デニール以下の極細フィラメント布等を綿球部の代わりとしたスワブも使用されているが、優れたワイピング性および不汚染性を併せ持つスワブは従来なかった。 In addition to cotton swabs, swabs using polyester knit cloth, polyurethane sponge, ultrafine filament cloth of 0.5 denier or less instead of cotton ball parts are also used. It was.
ポリエステルニット布は綿棒と同じく繊維が太く、ワイピング性に劣り、自己発塵性も大きい。ポリウレタンスポンジは拭き残りが少なく、対象も傷つけにくいが、ワイピング時多くの場合併用される溶媒に溶解もしくは膨潤し、溶媒に溶け出すポリウレタン成分により対象物を汚染する。極細フィラメント布は繊維が細く、対象物を傷つけにくいが、布であるが故に自己発塵性がある。 Polyester knitted fabrics are thick fibers like cotton swabs, are inferior in wiping properties, and have high self-dusting properties. Polyurethane sponges have little wiping residue and are less likely to damage the object, but often dissolve or swell in the solvent used together during wiping and contaminate the object with the polyurethane component that dissolves in the solvent. The ultrafine filament cloth has fine fibers and is difficult to damage an object, but is self-dusting because it is a cloth.
本発明は、拭き残りがなく、対象物を傷つけず、自己発塵性のない、溶媒溶出物もない従来技術ではなし得なかったスワブを提供する。 The present invention provides a swab that has not been wiped off, does not damage an object, is not self-dusting, and has no solvent eluate, which cannot be achieved by the prior art.
即ち本発明は、長さ2〜30cmの棒状物および先端が清拭部になっているスワブにおいて、清拭部がポリオレフィンスポンジからなり、棒状物への固定手段は、スポンジの中心部に穴を開けそこに棒状物を差し込む物理的な固定方法でも良いし、接着剤、熱融着等による固定方法等如何なる方法であってもよい。 That is, the present invention relates to a swab having a length of 2 to 30 cm and a swab whose tip is a wiping portion. The wiping portion is made of a polyolefin sponge, and the fixing means to the rod-like material has a hole in the center of the sponge. It may be a physical fixing method in which a rod-like object is inserted into the opening, or any method such as a fixing method using an adhesive, heat fusion, or the like.
次に本発明を詳細に説明する。 Next, the present invention will be described in detail.
本発明で言うポリオレフィンとはポリエチレン、ポリプロピレン、ポリスチレン等のオレフィンホモポリマ−並びにポリエチレン酢酸ビニル、同鹸化物、エチレン・プロピレン・スチレン・ブタジエン等の各種モノマーからなる高分子エラストマーを意味し、これらの混合物であってもよい。 The polyolefin referred to in the present invention means an olefin homopolymer such as polyethylene, polypropylene and polystyrene, and a polymer elastomer composed of various monomers such as polyethylene vinyl acetate, saponified product, ethylene, propylene, styrene and butadiene, and a mixture thereof. It may be.
ポリオレフィンをスポンジ化(発泡体化)するについては、ポリオレフィンにトリクロロフッ化メタン、テトラクロロジフッ化エタン、アゾジカルバナミド、パラトルエンスルフォニルヒドラジン等の発泡剤を混練し、押し出し、射出、圧縮により成形後、加熱発泡してもよいが(乾式発泡方式)、ポリオレフィンにアルギン酸、カルボキシメチルセルロース、ポリビニルアルコール、ポリアクリル酸ソーダ、各種デンプンの有機物および/又はナトリウム、カリウム、マグネシウム、カルシウム、ストロンチウム、アルミニウム等の塩化物、硫酸塩等の無機塩などの水溶性物質を混練し、押し出し、射出、圧縮により成形後、該水溶性物質を水中に溶出させてスポンジを得る方法(湿式発泡方式)であってもよい。 For making sponge (foaming) of polyolefin, foaming agent such as trichlorofluorinated methane, tetrachlorodifluorinated ethane, azodicarbanamide, para-toluenesulfonylhydrazine is kneaded into the polyolefin, and then extruded, injected, and compressed. After molding, it may be heated and foamed (dry foaming method), but polyolefins such as alginic acid, carboxymethylcellulose, polyvinyl alcohol, sodium polyacrylate, various starch organics and / or sodium, potassium, magnesium, calcium, strontium, aluminum, etc. This is a method (wet foaming method) in which a water-soluble substance such as an inorganic salt such as chloride or sulfate is kneaded, extruded, molded by injection and compression, and then the water-soluble substance is eluted in water to obtain a sponge. Also good.
ワイピング対象の汚れもしくは併用溶媒で希釈された汚れを拭き残りなく拭き取るためには、該汚れを、清拭部であるポリオレフィンスポンジで押し広げてしまう前に、素早く吸い取る必要がある。また対象物を傷つけないためにはクッション性が必要であり、該ポリオレフィンスポンジは、気孔径が小さくかつ気孔率が大きな連続気孔体でなければならない。具体的には、気孔径は150μm以下であって気孔率は50%以上でなければならない。
乾式発泡方式では、このような微細な孔径であって高気孔率の連続気孔体を再現性よく得ることはことは難しいので、湿式発泡方式の方が好ましい。
In order to wipe off the dirt to be wiped or the dirt diluted with the combined solvent without wiping, it is necessary to quickly suck the dirt before it is spread with the polyolefin sponge as the wiping portion. Further, cushioning properties are necessary to prevent the object from being damaged, and the polyolefin sponge must be a continuous pore body having a small pore diameter and a high porosity. Specifically, the pore diameter must be 150 μm or less and the porosity must be 50% or more.
In the dry foaming method, it is difficult to obtain a continuous pore body having such a fine pore diameter and a high porosity with good reproducibility, so the wet foaming method is preferable.
ワイピング時に併用される溶媒には、メチルアルコール、エチルアルコール、イソプロピルアルコール、アセトン、メチルエチルケトン、シクロヘキサン、酢酸エチル、ジクロロメタン、トリクロロエタン等が列挙されるが、ポリオレフィンはこれらの溶媒に溶解したり膨潤することはないので、併用溶媒に溶出するものはなく、対象物を汚染することはない。一方ポリウレタンスポンジはこれら溶媒に溶解もしくは膨潤する。
ポリオレフィンスポンジは、乾式発泡方式であっても湿式発泡方式であっても、一体物であり、編んだり、接着されたものではないので、自己発塵性はない。
Examples of solvents used in wiping include methyl alcohol, ethyl alcohol, isopropyl alcohol, acetone, methyl ethyl ketone, cyclohexane, ethyl acetate, dichloromethane, trichloroethane, etc. Since there is nothing, the combined solvent does not elute and does not contaminate the object. On the other hand, polyurethane sponge dissolves or swells in these solvents.
Polyolefin sponges, whether dry foaming or wet foaming, are monolithic and are not knitted or bonded, so they are not self-dusting.
電子部品、光学部品の小型化、集積度が進むにつれて、初期検査での不良率が大きくなり、初期検査で合格しても長期の使用で不良化する割合も大きくなる。不良率の低減、長期使用時における信頼性の向上を図るのに障害となる原因のひとつに塩素イオン、亜硝酸イオン、硝酸イオン、燐酸イオン、硫酸イオン等のアニオンによる汚染がある。特に塩素イオンが問題となる。このような場合は、純水にてポリオレフィンスポンジを洗浄することにより、残量塩素イオンを削減もしくは削除することが出来る。 As electronic parts and optical parts become smaller and more integrated, the defect rate at the initial inspection increases, and even if the initial inspection passes, the proportion of defects due to long-term use also increases. Contamination with anions such as chloride ion, nitrite ion, nitrate ion, phosphate ion and sulfate ion is one of the causes that hinder the reduction of the defect rate and the improvement of reliability during long-term use. In particular, chloride ions are a problem. In such a case, residual chlorine ions can be reduced or eliminated by washing the polyolefin sponge with pure water.
ポリオレフィンスポンジの棒状物への固定手段としては、接着剤、熱融着による固定方法も考えられるが、接着剤で固定すれば、接着剤が併用溶媒に溶出して対象物を汚染する恐れがあり、また熱融着で固定すれば、熱融着された部分が硬くなり、対象物を傷つける恐れがある。最も好ましい固定方法は、ポリオレフィンスポンジの中心部に穴を開け、そこに当該穴径より太い棒状物を差込み固定する方法である。この固定方法に従えば、ワイピングによりポリオレフィンスポンジが汚れれば、汚れたポリオレフィンスポンジを棒状物から抜き取り新しいポリオレフィンスポンジに差し替えれば、何回でも棒状物を繰り返し使用することが出来るメリットもある。 As a means of fixing the polyolefin sponge to the rod-like material, an adhesive or a method of fixing by heat fusion may be considered, but if the adhesive is fixed with an adhesive, the adhesive may elute into the combined solvent and contaminate the object. If fixed by heat fusion, the heat-sealed part becomes hard and the object may be damaged. The most preferable fixing method is a method in which a hole is formed in the central portion of the polyolefin sponge, and a rod-like object having a diameter larger than the hole diameter is inserted and fixed therein. According to this fixing method, if the polyolefin sponge is soiled by wiping, the rod-shaped material can be repeatedly used any number of times by removing the soiled polyolefin sponge from the rod-shaped material and replacing it with a new polyolefin sponge.
ポリオレフィンスポンジの中心部に穴を開けることは、ポリオレフィン混練物を成形する際、穴を開けておき、その後スポンジ化することにより容易に行うことが出来る。 Opening a hole in the center of the polyolefin sponge can be easily performed by forming a hole when forming a polyolefin kneaded product and then forming a sponge.
以下実施例にしたがって説明する。 This will be described in accordance with the following examples.
ポリオレフィン共重合物(三菱化学MKV(株)製ミラプレーンS8831 80重量部および三井化学(株)製三井ハイワックスNL100 20重量部の混合物)を160℃の2本ロールにて溶融状態にしてから、120℃まで温度を下げ、デキストリン(150重量部)を加え混練し、同温度で外径5mmのダイスと内径1mmのマンドレルから成る口金を取り付けたスクリュー径40mmφ、L/D27の単軸押出機から押し出しチューブ状物を得た。このチューブ状物を15mm長に切断し、それを80℃熱水中に浸漬し、デキストリンを溶出させ、乾燥した。得られたポリオレフィンスポンジの中心部にある穴に先端を円錐状に削った2mm径のポリプロピレン製軸を差込み、Aスワブを得た。 After a polyolefin copolymer (mixture of 80 parts by weight of Miraplane S8831 manufactured by Mitsubishi Chemical MKV Co., Ltd. and 20 parts by weight of Mitsui High Wax NL100 manufactured by Mitsui Chemicals Co., Ltd.) is melted with two rolls at 160 ° C, Lower the temperature to 120 ° C, add dextrin (150 parts by weight), knead, and from a single screw extruder with a screw diameter of 40 mmφ and L / D27 with a die consisting of a 5 mm outer diameter die and 1 mm inner diameter mandrel. An extruded tube was obtained. The tube was cut into a length of 15 mm and immersed in hot water at 80 ° C. to elute dextrin and dried. A 2 mm-diameter polypropylene shaft with a tip cut into a conical shape was inserted into a hole in the center of the obtained polyolefin sponge to obtain an A swab.
水中にデキストリンを溶出後、更に見掛け体積比で10倍量の純水(イオン交換水)に3回繰り返し浸漬する以外は実施例1と同様に実験を行い、Bスワブを得た。 After elution of dextrin in water, an experiment was carried out in the same manner as in Example 1 except that dipping was repeated three times in pure water (ion-exchanged water) of 10 times the apparent volume ratio to obtain B swab.
ポリウレタンスポンジを清拭部とするスワブとして、(株)ハーベストの商品名ルビスティックT-10を比較サンプル(Cスワブ)として選んだ。綿球、ポリエステルニット布、極細フィラメント布を清拭部とするスワブは自己発塵性があるので、比較対象とはしなかった。各スワブの清拭部について、気孔率、気孔径、溶媒溶出量、残留塩素イオン、吸い取り速度、表面傷つけ性を比較した結果は次表のとおりである。 As a swab using a polyurethane sponge as a wiping part, Harvest Co., Ltd.'s trade name Rubistick T-10 was selected as a comparative sample (C swab). Swabs with a cotton ball, polyester knit cloth, or ultrafine filament cloth as the wiping part have self-dusting properties and were not compared. The following table shows the results of a comparison of the porosity, pore diameter, solvent elution amount, residual chlorine ions, suction speed, and surface scratch resistance of each swab.
