Description

本発明はポリウレタンフォームなどの樹脂発泡体に関し、特にホルムアルデヒドなどの揮発性有機化合物の放散が抑制された樹脂発泡体に関するものである。また、本発明はこの樹脂発泡体の製造方法に関するものである。   The present invention relates to a resin foam such as polyurethane foam, and more particularly to a resin foam in which the diffusion of volatile organic compounds such as formaldehyde is suppressed. Moreover, this invention relates to the manufacturing method of this resin foam.

ホルムアルデヒドなどの揮発性有機化合物(VOC)は、シックハウス症候群や化学物質過敏症を引き起こす原因になることから、建物や車両の室内に使用される各種資材にはこれらの化合物を極力放散しないことが求められている。   Volatile organic compounds (VOC) such as formaldehyde cause sick house syndrome and chemical sensitivity, so it is required that these compounds are not released as much as possible to various materials used in buildings and vehicle interiors. It has been.

建築物や車両及び家電製品には、座席パッド、衝撃吸収材、断熱材、吸音材、エアシール材、水シール材などの種々の用途にポリウレタンフォームが用いられているが、これらの中には、ポリウレタンフォーム原料中に含まれていたり、ウレタン反応時に発生したりするホルムアルデヒドやアセトアルデヒドなどの揮発性有機化合物を放散するものもあり、その対策が求められている。   Polyurethane foam is used for various applications such as seat pads, shock absorbers, heat insulating materials, sound absorbing materials, air seal materials, water seal materials in buildings, vehicles and home appliances. Some of them emit volatile organic compounds such as formaldehyde and acetaldehyde that are contained in polyurethane foam raw materials or generated during urethane reaction, and countermeasures are required.

特許第3625141号公報(特開2000−86883)には、このウレタン組成物中にキャッチャー剤を配合することによりVOCの揮発を防止することが記載されている。   Japanese Patent No. 3625141 (Japanese Patent Laid-Open No. 2000-86883) describes that VOC volatilization is prevented by blending a catcher agent in this urethane composition.

また、特開2005−124743号公報には、シート用パッドの表面に消臭成分含有液をコーティングすることが記載されている。
特許3625141号公報 特開2005−124743号公報
Japanese Patent Application Laid-Open No. 2005-124743 describes that the surface of a sheet pad is coated with a deodorant component-containing liquid.
Japanese Patent No. 3625141 JP 2005-124743 A

ウレタン組成物中にキャッチャー剤を配合する場合、キャッチャー剤の多くが樹脂発泡体製品のウレタンマトリックス中に取り込まれたり、原材料と反応したりするため、十分なVOC放散防止効果を得るためには配合するキャッチャー剤の量が多くなり、コスト高となる。   When a catcher agent is blended in the urethane composition, most of the catcher agent is incorporated into the urethane matrix of the resin foam product or reacts with the raw material, so it is blended to obtain a sufficient VOC emission prevention effect. The amount of catcher agent to be increased increases the cost.

また、樹脂発泡体表面に消臭性コーティング剤を塗布した樹脂発泡体にあっては、コーティング材が樹脂発泡体表面から剥れ落ち易い。   Moreover, in the resin foam which apply | coated the deodorant coating agent on the resin foam surface, a coating material tends to peel off from the resin foam surface.

なお、キャッチャー剤を発泡体に含浸させることも考えられるが、この場合もキャッチャー剤が発泡体から離脱するおそれがある。   It is conceivable to impregnate the foam with the catcher agent, but in this case, the catcher agent may be detached from the foam.

本発明は、上記従来の問題点を解決し、キャッチャー剤の脱落が防止され、しかもVOCの揮発を十分に防止することができる樹脂発泡体と、その製造方法を提供することを目的とする。   An object of the present invention is to solve the above-mentioned conventional problems, and to provide a resin foam capable of preventing the catcher agent from falling off and sufficiently preventing VOC volatilization, and a method for producing the same.

請求項1の樹脂発泡体は、樹脂発泡体本体と、該樹脂発泡体本体の少なくとも一部の表面に保持された揮発性有機化合物を捕捉するキャッチャー剤とを有する樹脂発泡体において、該樹脂発泡体本体の該キャッチャー剤を保持した表面に粘着剤又は接着剤が付着されていることを特徴とするものである。   The resin foam according to claim 1 is a resin foam having a resin foam main body and a catcher agent that traps a volatile organic compound held on at least a part of the surface of the resin foam main body. A pressure-sensitive adhesive or an adhesive is attached to the surface of the body main body holding the catcher agent.

請求項2の樹脂発泡体は、請求項1において、前記樹脂発泡体本体はウレタンフォームであることを特徴とするものである。   The resin foam of claim 2 is characterized in that, in claim 1, the resin foam main body is urethane foam.

請求項3の樹脂発泡体は、請求項1又は2において、前記粘着剤又は接着剤が前記キャッチャー剤を覆っていることを特徴とするものである。   The resin foam according to claim 3 is characterized in that, in claim 1 or 2, the pressure-sensitive adhesive or adhesive covers the catcher agent.

請求項4の樹脂発泡体は、請求項3において、前記樹脂発泡体本体の前記表面にキャッチャー剤層と、該キャッチャー剤層を覆う粘着剤又は接着剤の層とが設けられていることを特徴とするものである。   The resin foam according to claim 4 is characterized in that, in claim 3, a catcher agent layer and an adhesive or adhesive layer covering the catcher agent layer are provided on the surface of the resin foam main body. It is what.

請求項5の樹脂発泡体は、請求項1ないし4のいずれか1項において、前記粘着剤又は接着剤を覆う離型紙又は離型フィルムを有することを特徴とするものである。   A resin foam according to a fifth aspect of the present invention is the resin foam according to any one of the first to fourth aspects, further comprising a release paper or a release film that covers the pressure-sensitive adhesive or adhesive.

請求項6の樹脂発泡体の製造方法は、請求項1ないし5のいずれか1項に記載の樹脂発泡体を製造する方法であって、前記該樹脂発泡体本体の少なくとも一部の表面にキャッチャー剤含有液を付着させた後、乾燥し、その後、該表面に粘着剤又は接着剤を付着させることを特徴とするものである。   A method for producing a resin foam according to claim 6 is a method for producing a resin foam according to any one of claims 1 to 5, wherein a catcher is provided on at least a part of the surface of the resin foam main body. After the agent-containing liquid is adhered, it is dried, and then the pressure-sensitive adhesive or adhesive is adhered to the surface.

本発明によって提供される樹脂発泡体にあっては、VOCを捕捉するためのキャッチャー剤を樹脂発泡体本体の表面に保持させているため、ウレタン組成物中にキャッチャー剤を配合する場合に比べてキャッチャー剤の使用量が少なくても十分にVOC放散防止効果を得ることができる。本発明では、この樹脂発泡体本体の表面に粘着剤又は接着剤を付着してあるので、キャッチャー剤の脱落も防止される。   In the resin foam provided by the present invention, the catcher agent for capturing the VOC is held on the surface of the resin foam main body. Even if the amount of the catcher agent used is small, a VOC emission preventing effect can be sufficiently obtained. In the present invention, since the pressure-sensitive adhesive or adhesive is adhered to the surface of the resin foam main body, the catcher agent is prevented from falling off.

この粘着剤又は接着剤がキャッチャー剤を覆うように構成することにより、例えば、樹脂発泡体本体の表面にキャッチャー剤層を形成し、その上に粘着剤又は接着剤の層を形成することにより、キャッチャー剤の脱落防止効果がより高いものとなる。   By configuring the pressure-sensitive adhesive or adhesive so as to cover the catcher agent, for example, by forming a catcher agent layer on the surface of the resin foam body, and forming a layer of the pressure-sensitive adhesive or adhesive on it, The effect of preventing the catcher agent from falling off becomes higher.

この粘着剤又は接着剤の層を覆う離型紙を設けた場合、製造工程や運搬途中において、樹脂発泡体が周囲部材に付着することが防止される。離型紙を剥すと、粘着力又は接着力により、樹脂発泡体を所望箇所に付着させることが可能となる。   When the release paper which covers this adhesive or adhesive layer is provided, it is possible to prevent the resin foam from adhering to the surrounding members during the manufacturing process and transportation. When the release paper is peeled off, the resin foam can be attached to a desired location by the adhesive force or adhesive force.

なお、樹脂発泡体本体としてはウレタンフォームが例示されるが、これに限定されない。   In addition, although urethane foam is illustrated as a resin foam main body, it is not limited to this.

本発明の樹脂発泡体を製造するには、キャッチャー剤含有液を樹脂発泡体本体に付着させた後、十分に乾燥し、その後、粘着剤又は接着剤を塗工接着させるのが好ましい。   In order to produce the resin foam of the present invention, it is preferable that the catcher agent-containing liquid is attached to the resin foam main body, and then sufficiently dried, and then a pressure-sensitive adhesive or an adhesive is applied and adhered.

以下、図面を参照して実施の形態について説明する。   Hereinafter, embodiments will be described with reference to the drawings.
