詳しくは、塩化ビニル樹脂と、可塑剤や安定剤などの添加剤からなる組成物を成形した給水給湯用ホースに関する。
The present invention relates to a water supply hot water supply hose made of a vinyl chloride resin used for water supply and hot water supply such as a shower hose.
More specifically, the present invention relates to a water and hot water supply hose obtained by molding a composition comprising a vinyl chloride resin and additives such as a plasticizer and a stabilizer.
従来、この種の給水給湯用ホースとして、塩化ビニル樹脂に、臭気がある有機スズ系安定剤に代え、主安定剤としてCa-Zn系又はBa-Zn系の金属せっけん系安定剤（亜鉛系有機安定剤）を配合し、更にホスファイト（亜リン酸トリエステル）系の安定化助剤（キレーター）を併用することにより、臭気の発生を改善したものがある（例えば、特許文献１参照）。 Conventionally, as this type of water and hot water supply hose, instead of organotin stabilizers with odor in vinyl chloride resin, Ca-Zn or Ba-Zn metal soap stabilizers (zinc organic) There is one in which the generation of odor is improved by blending a stabilizer) and further using a phosphite (phosphite triester) -based stabilization aid (chelator) together (for example, see Patent Document 1).
しかし乍ら、このような従来の給水給湯用ホースでは、安定化助剤として配合されたホスファイト中にフェノールが残存すると共に該ホスファィトの加水分解でフエノールが生成されるため、このホース内に水道水を通水すると、塩素で水道水を消毒する際に生じる塩酸や次亜塩素酸が上記フェノールと反応してクロル化され、このクロル化で生じるクロルフェノールやジクロルフェノールなどが臭気の原因となるという問題があった。
特に、クロルフェノールやジクロルフェノールの臭気はフェノールの500倍あり、低濃度でも臭気を感じた。
However, in such a conventional water and hot water supply hose, phenol remains in the phosphite compounded as a stabilizing aid and phenol is generated by hydrolysis of the phosphite. When water is passed, hydrochloric acid and hypochlorous acid generated when disinfecting tap water with chlorine reacts with the above phenols and chlorinates. Chlorphenol and dichlorophenol generated by this chlorination cause odor. There was a problem of becoming.
In particular, the odor of chlorophenol and dichlorophenol was 500 times that of phenol, and the odor was felt even at low concentrations.
本発明のうち請求項１記載の発明は、フェノールとの反応による臭気の発生を防止することを目的としたものである。
請求項２記載の発明は、請求項１に記載の発明の目的に加えて、加熱成形時の変色を防止することを目的としたものである。
請求項３記載の発明は、請求項１または２に記載の発明の目的に加えて、ブリードによる安定性の低下を防止することを目的としたものである。
The invention according to claim 1 of the present invention aims to prevent the generation of odor due to reaction with phenol.
In addition to the object of the invention described in claim 1, the invention described in claim 2 aims to prevent discoloration during heat molding.
In addition to the object of the invention described in claim 1 or 2, the invention described in claim 3 is intended to prevent a decrease in stability due to bleeding.
前述した目的を達成するために、本発明のうち請求項１記載の発明は、塩化ビニル樹脂と、可塑剤や安定剤などの添加剤からなる組成物を成形した給水給湯用ホースにおいて、前記添加剤からフェノールと、水道水との反応によってフェノールを発生する材料を排除したことを特徴とするものである。
ここで、水道水との反応によってフェノールを発生する材料とは、例えば安定化助剤として配合されるホスファイトなどである。
請求項２記載の発明は、請求項１記載の発明の構成に、成形されたホースの少なくとも外皮層に顔料を添加して着色した構成を加えたことを特徴とする。
請求項３記載の発明は、請求項１または２記載の発明の構成に、成形されたホースの少なくとも外皮層に紫外線吸収剤を添加した構成を加えたことを特徴とする。
In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a water supply / hot water hose in which a composition comprising a vinyl chloride resin and an additive such as a plasticizer or a stabilizer is formed. It is characterized in that a material that generates phenol by the reaction of phenol and tap water from the agent is excluded.
Here, the material that generates phenol by reaction with tap water is, for example, phosphite blended as a stabilizing aid.
The invention described in claim 2 is characterized in that, in addition to the structure of the invention described in claim 1, a structure obtained by adding a pigment to at least the outer skin layer of the molded hose is added.
The invention described in claim 3 is characterized in that a structure in which an ultraviolet absorber is added to at least the outer skin layer of the molded hose is added to the structure of the invention described in claim 1 or 2.
以上説明したように、本発明のうち請求項１記載の発明は、添加剤からフェノールと、水道水との反応によってフェノールを発生する材料を排除することにより、ホース内に水道水が通水されてもフェノールが抽出されず、臭気の原因であるクロルフェノールやジクロルフェノールの発生も防止される。
従って、フェノールとの反応による臭気の発生を防止することができる。
その結果、安定化助剤として配合されたホスファイト中にフェノールが残存するだけでなく該ホスファィトの加水分解でフエノールが更に生成される従来のものに比べ、臭気を気にすることなく安心して使用できる。
更に、水道法に規定された「給水装置に係わる器具等の溶出試験」におけるフェノールの抽出量を０．００５ｐｐｍ以下に抑えてクリアできる。
As described above, the invention according to claim 1 of the present invention allows tap water to pass through the hose by excluding the material that generates phenol by the reaction of phenol and tap water from the additive. However, phenol is not extracted, and generation of chlorophenol and dichlorophenol, which cause odor, is prevented.
Therefore, generation of odor due to reaction with phenol can be prevented.
As a result, it is safe to use without worrying about odors compared to conventional phosphites formulated as stabilizing aids, as well as phenol not only remains but also phenol is generated by hydrolysis of the phosphites. it can.
Furthermore, the extraction amount of phenol in the “elution test of appliances related to water supply apparatus” stipulated in the Water Supply Law can be cleared to 0.005 ppm or less.
請求項２の発明は、請求項１の発明の効果に加えて、成形されたホースの少なくとも外皮層に顔料を添加して着色することにより、フェノール系の安定剤を使えないことが原因で、加熱成形時に変色しても目立たない。
従って、加熱成形時の変色を防止することができる。
In addition to the effect of the invention of claim 1, the invention of claim 2 is because a phenolic stabilizer cannot be used by adding a pigment to at least the outer skin layer of the molded hose and coloring it. Not noticeable even when discolored during thermoforming.
Therefore, discoloration during heat molding can be prevented.
請求項３の発明は、請求項１または２の発明の効果に加えて、成形されたホースの少なくとも外皮層に紫外線吸収剤を添加することにより、フェノール系の安定剤を使えないことが原因で耐候性が低下してブリードが発生し易くなっても、外皮層に添加した紫外線吸収剤で紫外線を吸収して耐候性が向上する。
従って、ブリードによる安定性の低下を防止することができる。
In addition to the effect of the invention of claim 1 or 2, the invention of claim 3 is because a phenol-based stabilizer cannot be used by adding an ultraviolet absorber to at least the outer skin layer of the molded hose. Even if the weather resistance is lowered and bleeding is likely to occur, the ultraviolet ray is absorbed by the ultraviolet absorbent added to the outer skin layer, and the weather resistance is improved.
Accordingly, it is possible to prevent a decrease in stability due to bleeding.
以下、本発明の一実施例を説明する。
本発明の給水給湯用ホースは、例えばポリ塩化ビニル（ＰＶＣ）などの軟質塩化ビニル樹脂と、可塑剤や安定剤などの添加剤からなる組成物を押出成形して、可撓性に優れたシャワーホースを製造する場合を示すものである。
An embodiment of the present invention will be described below.
The water and hot water supply hose of the present invention is a shower having excellent flexibility by extruding a composition comprising a soft vinyl chloride resin such as polyvinyl chloride (PVC) and additives such as a plasticizer and a stabilizer. The case where a hose is manufactured is shown.
上記可塑剤や安定剤などの添加剤の中からフェノールを排除すると共に、水道水との反応によってフェノールを発生する材料を排除する。
即ち、上記添加剤として、可塑剤や安定剤などにフェノールが含有されない従来周知な非フェノール系の可塑剤や安定剤などを使用し、更に安定化助剤として一般的に配合される例えばホスファイト（亜リン酸トリエステル）のようなフェノールが残存すると共にその加水分解でフェノールが生成されるものも除外する。
While excluding phenol from additives such as the plasticizer and stabilizer, materials that generate phenol by reaction with tap water are excluded.
That is, as the additive, a conventionally well-known non-phenolic plasticizer or stabilizer that does not contain phenol in a plasticizer or stabilizer is used, and is generally added as a stabilizing aid, for example, phosphite. Also excluded are phenols such as (phosphorous acid triester) that remain and at the same time hydrolysis produces phenol.
上記ホスファイトの添加は、特にポリ塩化ビニル組成物の耐候性を向上させる機能があるが、このホスファイトの使用を除外すると、耐候性が著しく低下し、加熱成形時に例えば黄色に変色し易くなると共に、日光などの紫外線が照射されると、ブリードを生じ易くなる。 The addition of the above phosphite has a function of improving the weather resistance of the polyvinyl chloride composition in particular. However, if the use of this phosphite is excluded, the weather resistance is remarkably lowered, and it easily changes to yellow, for example, at the time of heat molding. At the same time, when ultraviolet rays such as sunlight are irradiated, bleeding easily occurs.
これらの問題を解決するために、加熱成形時に発生する変色の対策としては、成形されたホースの少なくとも外皮層に顔料を添加して、例えば黒色などのような黄色への変色が発生しても目立たない濃い色に着色する。 In order to solve these problems, as a countermeasure for discoloration that occurs during heat molding, even if a pigment is added to at least the outer skin layer of the molded hose, discoloration to yellow such as black occurs, for example Color in an inconspicuous dark color.
更に、紫外線によって発生するブリードの対策としては、成形されたホースの少なくとも外皮層に紫外線吸収剤を添加すると共に、用途を紫外線の影響が少ない室内に限定することで、耐候性を向上してブリードが生じないようにする。 Furthermore, as a countermeasure against bleeding caused by ultraviolet rays, an ultraviolet absorber is added to at least the outer skin layer of the molded hose, and the use is limited to a room where the influence of ultraviolet rays is small, thereby improving weather resistance and bleeding. Make sure that does not occur.
また、成形されたホースの内部には、単数又は複数本のブレード（補強糸）を螺旋状に巻き付けて一体化したり、断面円形の線状補強材を螺旋状に巻き付けて一体化したり、これらブレードや線状補強材に代えて、例えばガラス繊維や難燃性繊維などの糸状補強材を編組するか、又は螺旋状に巻き付けて一体化するか、或いは単層構造のものでも良い。 In addition, one or a plurality of blades (reinforcing yarns) are spirally wound and integrated inside the molded hose, or a linear reinforcing material having a circular cross section is spirally wound and integrated. Instead of the wire reinforcing material or the linear reinforcing material, for example, a yarn-like reinforcing material such as glass fiber or flame retardant fiber may be braided, wound spirally, or integrated, or may have a single layer structure.
次に、斯かる給水給湯用ホースの作用について説明する。
軟質塩化ビニル樹脂に対する添加剤からフェノールと、水道水との反応によってフェノールを発生する材料、具体的には安定化助剤として配合されるホスファイトを排除したため、該給水給湯用ホース内に水道水が通水されてもフェノールが抽出（生成）されず、このフェノールと水道水中に含まれる塩素とで塩酸や次亜塩素酸が生成されないと共に、そのクロル化で生じるクロルフェノールやジクロルフェノールなども発生しない。
Next, the operation of such a water / hot water supply hose will be described.
Since the material for generating phenol by reaction of phenol and tap water from the additive to the soft vinyl chloride resin, specifically, phosphite blended as a stabilizing aid has been excluded, tap water is contained in the water supply / hot water hose. Phenol is not extracted (produced) even when water is passed through, and hydrochloric acid and hypochlorous acid are not produced with this phenol and chlorine contained in tap water. Chlorphenol and dichlorophenol produced by chlorination are also produced. Does not occur.
その結果、臭気の主な原因であるクロルフェノールやジクロルフェノール（臭気がフェノールの500倍も発する）が発生しないから臭気を気にせず安心して使用できる。
しかも、実験によれば、水道法に規定された「給水装置に係わる器具等の溶出試験」におけるフェノールの抽出量を０．００５ｐｐｍ以下に抑えてクリアできることが判った。
As a result, chlorophenol and dichlorophenol, which are the main causes of odor, do not occur, and can be used safely without worrying about odor.
Moreover, according to experiments, it was found that the extraction amount of phenol in the “elution test of appliances and the like related to the water supply apparatus” stipulated in the Water Supply Law can be cleared to 0.005 ppm or less.
また、このようなフェノールが排除された塩化ビニル組成物から斯かる給水給湯用ホースを製造するには、先ず、軟質塩化ビニル樹脂と、可塑剤や安定剤などの添加剤をミキサーに投入して配合した後に、これを成形装置(押出し機)で押出成形するが、これらミキサーや成形装置のシリンダー内やスクリュなどに、その前にホスファイトが添加されたホースを製造した際のホスファイト残渣が僅かでも残っていると、ホスファイトが混入して所期の目的を達成できないため、専用のミキサーや製造ラインを用意することが好ましい。 In order to produce such a water supply hot water supply hose from such a vinyl chloride composition from which phenol is excluded, first, a soft vinyl chloride resin and additives such as a plasticizer and a stabilizer are added to a mixer. After blending, this is extruded with a molding device (extruder), but the phosphite residue when producing hoses with phosphite added to the cylinders and screws of these mixers and molding devices is added. If even a small amount remains, phosphite is mixed and the intended purpose cannot be achieved, so it is preferable to prepare a dedicated mixer and production line.
更に本実施例の場合には、成形されたホースの少なくとも外皮層に顔料を添加して着色したため、例えばホスファィトなどのフェノール系安定剤を使えないことが原因で、加熱成形時に変色しても目立たない。
その結果、加熱成形時の変色を防止できるという利点がある。
Furthermore, in the case of this example, since pigment was added to at least the outer skin layer of the molded hose and colored, for example, a phenol-based stabilizer such as phosphite could not be used, so it was noticeable even when the color was changed during heat molding. Absent.
As a result, there is an advantage that discoloration during heat molding can be prevented.
更にまた、成形されたホースの少なくとも外皮層に紫外線吸収剤を添加したため、例えばホスファィトなどのフェノール系安定剤を使えないことが原因で耐候性が低下してブリードが発生し易くなっても、外皮層に添加した紫外線吸収剤で紫外線を吸収して耐候性が向上する。
その結果、ブリードによる安定性の低下を防止できるという利点がある。
Furthermore, since an ultraviolet absorber is added to at least the outer skin layer of the molded hose, for example, a phenolic stabilizer such as phosphite cannot be used. The weather resistance is improved by absorbing ultraviolet rays with an ultraviolet absorber added to the skin layer.
As a result, there is an advantage that a decrease in stability due to bleeding can be prevented.
尚、前示実施例では、軟質塩化ビニル樹脂と、可塑剤や安定剤などの添加剤からなる組成物を押出成形して、可撓性に優れたシャワーホースを製造する場合を示したが、これに限定されず、シャワーホース以外の給水給湯用ホースであっても上述した作用効果と同様な作用効果を奏することができる。 In the previous examples, a case of producing a shower hose excellent in flexibility by extruding a composition comprising a soft vinyl chloride resin and additives such as a plasticizer and a stabilizer, It is not limited to this, Even if it is water supply hot water supply hoses other than a shower hose, there can exist an effect similar to the effect mentioned above.
