【考案の詳細な説明】
この考案は冷媒、LPGなどのガス輸送用ホース
に係り、可撓性、ガス不透過性にすぐれたプラス
チツクホースを提供せんとするものである。ガス
輸送用ホースとしては従来からゴムホースが用い
られていたが、ゴムホースはフレオンなどが透過
し易い抽出物により機能が低下する、などの欠点
があるため、これら欠点のない各種プラスチツク
材を用いたホースが提案され、一部実用に供され
ている。[Detailed description of the invention] This invention relates to a hose for transporting gases such as refrigerant and LPG, and aims to provide a plastic hose with excellent flexibility and gas impermeability. Rubber hoses have traditionally been used as gas transport hoses, but rubber hoses have drawbacks such as reduced functionality due to extractables that allow Freon and other substances to easily permeate, so hoses made of various plastic materials that do not have these drawbacks have been developed. have been proposed and some have been put into practical use.
しかしガス不透過性にすぐれたプラスチツク
材、例えば、ポリ塩化ビニリデン、共重合ナイロ
ン６−66、同６−12などは可撓性や耐熱性が劣
り、可撓性や耐熱性に問題のないナイロン11、同
12などは若干不透過性が劣るという欠点がある。
この提案は斯かる点に鑑みてなされたもので、そ
の要旨はナイロン11或るいはナイロン12から成る
ホースの外周面上に、銅やアルミニウム等の金属
から成る蒸着層或るいはメツキ層が形成されてな
るガス輸送用プラスチツクホースにある。 However, plastic materials with excellent gas impermeability, such as polyvinylidene chloride, copolymerized nylon 6-66, and copolymerized nylon 6-12, have poor flexibility and heat resistance, while nylon, which has no problems with flexibility or heat resistance, 11, same
12 etc. have the disadvantage of slightly inferior opacity.
This proposal was made in view of these points, and its gist is that a vapor deposited or plating layer made of a metal such as copper or aluminum is formed on the outer circumferential surface of a hose made of nylon 11 or nylon 12. Plastic hoses used for gas transportation.
これを添付図面に示すす例を参照して説明すれ
ば、第１図はナイロン12製のチユーブ１の外面に
蒸着法、メツキ法などによつて、銅、アルミニウ
ムなどの薄い金属の層２１を直接被着し、その上
に編組補強層３、ポリウレタン製の保護層４を順
次施したものである。 To explain this with reference to an example shown in the attached drawings, FIG. 1 shows a thin metal layer 21 such as copper or aluminum coated on the outer surface of a tube 1 made of nylon 12 by vapor deposition or plating. A braided reinforcing layer 3 and a protective layer 4 made of polyurethane are sequentially applied thereon.
この場合、継目のない金属の層２１が得られる
のでガスの透過がなく有効であり、またその金属
層は蒸着法やメツキ法により形成したものである
ため、ナイロン12の特性を損なうことがない。 In this case, a seamless metal layer 21 is obtained, which is effective because there is no gas permeation, and since the metal layer is formed by a vapor deposition method or a plating method, the properties of nylon 12 are not impaired. .
この金属の層２１は内面に施してもよく、露出
する面は保護のためにプラスチツクをコーテイン
グしてもよい。 This metal layer 21 may be applied to the inner surface, and the exposed surfaces may be coated with plastic for protection.
第２図は蒸着法、メツキ法などによつて金属の
薄い層２２が予め施されたプラスチツクフイルム
２３のテープ巻層をチユーブ１の外面に施したも
のである。 In FIG. 2, a tape-wrapped layer of plastic film 23 on which a thin metal layer 22 has been previously applied by vapor deposition, plating, etc., is applied to the outer surface of the tube 1.
これらの例からも明らかなように、この考案の
ホース表面に金属蒸着層或るいは金属メツキ層を
形成したものであるため、可撓性や耐熱性に問題
のない材料を用いても可撓性を損うことがなく、
ガスの透過も金属の層によつて阻止、減少させる
ことができるなどの利点があり、その実用価値は
大なるものがある。 As is clear from these examples, since the hose of this invention has a metal vapor-deposited layer or a metal plating layer formed on the surface, it is not flexible even if materials with no problems in flexibility or heat resistance are used. without compromising sex,
The metal layer has the advantage of being able to prevent or reduce gas permeation, and has great practical value.
因に、ナイロン12製のチユーブについて、100℃
雰囲気中でのフレオン（R12）の透過量をみる
と、チユーブだけのものは96時間で９ｇ／46cmで
あつたが、アルミ蒸着フイルムを巻付けたものは
2.5ｇ／46cm、銅メツキフイルムを巻付けたもの
は1.3ｇ／46cmであつた。Incidentally, for tubes made of nylon 12, temperature at 100℃
Looking at the amount of Freon (R12) permeated in the atmosphere, the tube alone had a rate of 9 g/46 cm in 96 hours, but the tube wrapped with aluminum vapor deposition film had a permeation rate of 9 g/46 cm.
The weight was 2.5g/46cm, and the weight was 1.3g/46cm wrapped with copper film.
