Description

本発明は、架橋ポリオレフィン系樹脂発泡体に、消臭機能又は抗菌機能を有するポリオレフィン系樹脂フィルムを積層した積層発泡体に関する。   The present invention relates to a laminated foam obtained by laminating a polyolefin resin film having a deodorizing function or an antibacterial function on a crosslinked polyolefin resin foam.

架橋ポリオレフィン系樹脂発泡体は、金属屋根断熱材、エアコン配管用被覆断熱材、自動車用内装材をはじめ、スポーツマット、台所マット、バスマット、輸送用緩衝材、寝具芯材、緊急避難所用防災マット等に広く用いられている。   Cross-linked polyolefin resin foam includes metal roof insulation, insulation insulation for air conditioner piping, automotive interior materials, sports mats, kitchen mats, bath mats, transport cushioning materials, bedding core materials, emergency shelter disaster prevention mats, etc. Widely used in

最近では、特にマットや輸送用緩衝材、寝具芯材等で使用時の安全性や清潔性の要求が高まってきており、消臭性や抗菌性の要求が出てきている。これらの要求に対して、従来の架橋ポリオレフィン系樹脂発泡体では、ポリオレフィン系樹脂に消臭剤や抗菌剤を混合して発泡させることが検討されていた(特許文献1、2)。   Recently, there has been an increasing demand for safety and cleanliness during use, particularly for mats, cushioning materials for transport, bedding core materials, and the like, and there have been demands for deodorization and antibacterial properties. In response to these demands, it has been studied to foam a conventional crosslinked polyolefin resin foam by mixing a polyolefin resin with a deodorant or an antibacterial agent (Patent Documents 1 and 2).

特開2008−062497号公報JP 2008-062497 A 特開2009−051155号公報JP 2009-051155 A

ところが、この方法によると、架橋ポリオレフィン系樹脂発泡体が基本的に独立気泡であるため、ポリオレフィン系樹脂に消臭剤や抗菌剤を添加してもその機能を有効に発揮するのは、架橋ポリオレフィン系樹脂発泡体の表層面のみであり、埋没した消臭剤や抗菌剤は効果が発現せず、全体に消臭剤や抗菌剤を添加することは無駄なコストアップを招くことになり好ましくない。   However, according to this method, since the cross-linked polyolefin resin foam is basically closed cells, the function is effectively exhibited even if a deodorant or antibacterial agent is added to the polyolefin resin. It is only the surface layer surface of the resin-based resin foam, the embedded deodorant and antibacterial agent are not effective, and it is not preferable to add the deodorant and antibacterial agent to the whole because it causes unnecessary cost increase. .

架橋ポリオレフィン系樹脂発泡体の独立気泡を連続気泡にするためにロールで潰して気泡の一部を破壊する方法もあるが、破泡しやすくする為の低架橋の配合は、製造安定性が低く制御が難しいことから、歩留悪化を招きコストアップに繋がる。   In order to make closed cells of the cross-linked polyolefin resin foam into continuous cells, there is a method of crushing with a roll to destroy some of the bubbles, but the low cross-linking formulation to make it easy to break the foam has low manufacturing stability. Since it is difficult to control, the yield is deteriorated and the cost is increased.

更に、消臭剤や抗菌剤の粉体をポリオレフィン系樹脂に添加すると、その成分によっては、発泡剤の分解温度の低下や分解促進作用を起こして、架橋と発泡のタイミングにずれを生じさせて発泡阻害を引き起すことが多く、消臭剤や抗菌剤の種類について選択の幅が制限される。   Furthermore, when deodorant and antibacterial powders are added to polyolefin resin, depending on the component, the decomposition temperature of the foaming agent may be lowered and the decomposition may be accelerated, causing a shift in the timing of crosslinking and foaming. It often causes foaming inhibition and limits the range of choices for the type of deodorant and antibacterial agent.

そこで、消臭剤や抗菌剤を架橋ポリオレフィン系樹脂発泡体に添加するのではなく、フィルムや不織布に添加してこれを架橋ポリオレフィン系樹脂発泡体の表面に貼り付けることが考えられる。こうすることにより、表層面にのみ消臭剤や抗菌剤を配置することができるので、消臭剤や抗菌剤の使用量を最小限にすることができ、コスト的に有利となる。しかし、消臭剤、抗菌剤を含むフィルムや不織布を架橋ポリオレフィン系樹脂発泡体の片面のみに貼り付けた積層発泡体は、熱膨張率の差により、反りを生じやすく、緊急避難所用マット、スポーツマット等、平板状が要求される用途では反りの低減が求められる。   Therefore, it is conceivable that a deodorizing agent or an antibacterial agent is not added to the cross-linked polyolefin resin foam, but is added to a film or non-woven fabric and this is attached to the surface of the cross-linked polyolefin resin foam. By doing so, since the deodorant and the antibacterial agent can be arranged only on the surface, the amount of the deodorant and the antibacterial agent can be minimized, which is advantageous in terms of cost. However, laminated foams with films or non-woven fabrics containing deodorants and antibacterial agents attached to only one side of a cross-linked polyolefin resin foam are prone to warping due to differences in thermal expansion coefficient. Reduction of warpage is required in applications such as mats where flat plate shapes are required.

本発明はかかる背景に鑑み、従来技術より効率的に消臭性や抗菌性を有し、且つ反りの少ない、ポリオレフィン系樹脂を用いた積層発泡体を提供するものである。   In view of such a background, the present invention provides a laminated foam using a polyolefin-based resin having deodorizing properties and antibacterial properties more efficiently than conventional techniques and having less warpage.

以下、本発明の一実施形態について説明する。本実施の形態の積層発泡体は、架橋ポリオレフィン系樹脂発泡体の一方の面に配置され、消臭剤又は抗菌剤を含む厚さ50〜160μmのポリオレフィン系樹脂フィルムと、他方の面に配置され、前記一方の面に設けたポリオレフィン系樹脂フィルムの50〜85%の厚さであって、消臭剤及び抗菌剤を含まないポリオレフィン系樹脂フィルムと、を表層面に有する。ここで、表層面とは、架橋ポリオレフィン系樹脂発泡体とポリオレフィン系樹脂フィルムとを積層した積層発泡体の全体としての最表面のことをいい、以下、同様である。   Hereinafter, an embodiment of the present invention will be described. The laminated foam of the present embodiment is disposed on one surface of the crosslinked polyolefin resin foam, and is disposed on the other surface of a polyolefin resin film having a thickness of 50 to 160 μm containing a deodorant or an antibacterial agent. The polyolefin resin film having a thickness of 50 to 85% of the polyolefin resin film provided on the one surface and containing no deodorant and antibacterial agent is provided on the surface layer. Here, the surface layer means the outermost surface of the entire laminated foam obtained by laminating a cross-linked polyolefin resin foam and a polyolefin resin film, and the same applies hereinafter.

本実施の形態における積層発泡体は、芯材となる架橋ポリオレフィン系樹脂発泡体の表裏面の両側に、表層材となるポリオレフィン系樹脂フィルムが積層されたものであり、いわゆるポリオレフィン系樹脂積層発泡体である。用途としては、断熱材、内装材、マット、緩衝材等が挙げられる。   The laminated foam in the present embodiment is obtained by laminating a polyolefin resin film as a surface layer material on both sides of the front and back surfaces of a crosslinked polyolefin resin foam as a core material, so-called polyolefin resin laminated foam. It is. Applications include heat insulating materials, interior materials, mats, cushioning materials, and the like.

架橋ポリオレフィン系樹脂発泡体とは、上述した積層発泡体の芯材となるものであり、芯材とは、ポリオレフィン系樹脂フィルムを積層する際の支持体となるものである。また、架橋ポリオレフィン系樹脂発泡体とは、オレフィン系樹脂と発泡剤等の混練物を公知の方法で、架橋ポリオレフィン系樹脂を発泡させることにより得ることができる。架橋ポリオレフィン系樹脂発泡体のポリオレフィン系樹脂としては、低密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、エチレン−ポリプロピレン共重合体、オレフィン系熱可塑性エラストマー等が挙げられ、更にエチレン−酢酸ビニル共重合体、エチレン−エチルアクリレート共重合体、エチレン−ジエン共重合体、エチレン−ジエン−3元共重合体等も用いることができる。なお、これらは単独あるいは2種類以上を組み合わせて使用することもできる。架橋は有機化酸化物等を用いるいわゆる化学架橋や電子線架橋による。発泡体の発泡倍率は、使用目的によって任意に選ぶことができ、一般的には10倍から40倍のものが多用される。発泡倍率とは、発泡体の体積を発泡体の質量で割った値である。   The cross-linked polyolefin resin foam is a core material of the above-mentioned laminated foam, and the core material is a support body when the polyolefin resin film is laminated. The crosslinked polyolefin-based resin foam can be obtained by foaming a crosslinked polyolefin-based resin with a kneaded material such as an olefin-based resin and a foaming agent by a known method. Examples of the polyolefin resin of the crosslinked polyolefin resin foam include low-density polyethylene, high-density polyethylene, polypropylene, ethylene-polypropylene copolymer, and olefin-based thermoplastic elastomer, and further ethylene-vinyl acetate copolymer and ethylene. An ethyl acrylate copolymer, an ethylene-diene copolymer, an ethylene-diene-ternary copolymer, or the like can also be used. In addition, these can also be used individually or in combination of 2 or more types. Crosslinking is based on so-called chemical crosslinking or electron beam crosslinking using an organic oxide or the like. The foaming ratio of the foam can be arbitrarily selected depending on the purpose of use, and generally 10 to 40 times is often used. The expansion ratio is a value obtained by dividing the volume of the foam by the mass of the foam.

また、架橋ポリオレフィン系樹脂発泡体のポリオレフィン系樹脂には目的に応じて、塩素系、臭素系、リン系化合物、三酸化アンチモン等のアンチモン化号物、水酸化アルミニウム、水酸化マグネシウム等の難燃剤、炭酸カルシウム、タルク等の充填剤を添加したものを用いることができる。   In addition, depending on the purpose, the polyolefin resin of the cross-linked polyolefin resin foam may be a chlorine, bromine, phosphorus compound, antimony compound such as antimony trioxide, or a flame retardant such as aluminum hydroxide or magnesium hydroxide. , Calcium carbonate, talc and other fillers can be used.

架橋ポリオレフィン系樹脂発泡体の形状は、断熱材、内装材、マット、緩衝材等の用途に用いるのに適したものであれば特に限定はない。このような形状としては、表裏面と側面とを有し、表裏面の面積が側面の面積に対して大きい平板状、シート状、フィルム状等が挙げられる。   The shape of the crosslinked polyolefin resin foam is not particularly limited as long as it is suitable for use in applications such as a heat insulating material, an interior material, a mat, and a cushioning material. Examples of such a shape include a flat plate shape, a sheet shape, and a film shape that have front and back surfaces and side surfaces, and the front and back surface areas are larger than the side surface areas.

架橋ポリオレフィン系樹脂発泡体の厚さは、使用目的に応じて任意に選択することができ、本発明を制限するものではないが、一般的には3〜10mmが好適である。なお、架橋ポリオレフィン系樹脂発泡体の厚さは、JIS A 9511に準じた測定方法で測定した数値である。   The thickness of the crosslinked polyolefin resin foam can be arbitrarily selected according to the purpose of use and is not intended to limit the present invention, but generally 3 to 10 mm is preferable. The thickness of the crosslinked polyolefin resin foam is a numerical value measured by a measuring method according to JIS A 9511.

本実施の形態に用いる消臭剤とは、臭気の原因物質を化学的に変化させて除去するものをいう。消臭剤としては、無機系化合物と有機系化合物があり、無機系化合物では、銀イオンや亜鉛イオンを有する珪酸塩化合物、銀イオンや亜鉛イオンを有するリン酸塩化合物、銀イオンや亜鉛イオンを有するリン酸カルシウム化合物、活性炭、ホタテ貝殻を焼成した水酸化カルシウム(ホタテ貝殻の焼成物)を主成分とするものが例示される。ここで、主成分とは、その成分が含まれる化合物の全成分の合計を100質量%としたとき、その成分が50質量%以上100質量%以下含まれることをいう。有機系化合物では、分子内に複数のベンゼン環やナフタレン環等の芳香環に結合したヒドロキシ基を有する化合物が例示される。また、シリカやゼオライトに臭気対象物質と化学反応又は臭気対象物質を吸着する有機系官能基を担持させたものも有用である。これらの中でもホタテ貝殻を焼成した水酸化カルシウム(ホタテ貝殻の焼成物)を主成分とする粉体は、消臭機能とあわせて抗菌機能も有するので、好適である。添加量は特に規定しないが、それぞれの消臭剤の性能を発揮する添加量にすることが好ましい。一般的には、ポリオレフィン系樹脂フィルムのポリオレフィン系樹脂100質量部に対し、1〜10質量部が好ましい。添加量が1質量部以上であると消臭機能を発揮可能あり、10質量部以下であるとコストを抑制できるためである。   The deodorant used in the present embodiment refers to an agent that removes the odor-causing substance by changing it chemically. Deodorants include inorganic compounds and organic compounds. In inorganic compounds, silicate compounds having silver ions and zinc ions, phosphate compounds having silver ions and zinc ions, silver ions and zinc ions are used. The thing which has as a main component calcium hydroxide (calcined scallop shell) which calcined the calcium phosphate compound which has, activated carbon, and scallop shell is illustrated. Here, the main component means that the component is contained in an amount of 50% by mass or more and 100% by mass or less when the total of all components of the compound including the component is 100% by mass. Examples of the organic compound include compounds having a hydroxy group bonded to an aromatic ring such as a plurality of benzene rings or naphthalene rings in the molecule. Moreover, what carried | supported the organic functional group which adsorb | sucks a odor object substance, a chemical reaction, or an odor object substance to silica or a zeolite is also useful. Among these, a powder mainly composed of calcium hydroxide (baked scallop shell) fired from scallop shell is preferable because it has an antibacterial function as well as a deodorizing function. The addition amount is not particularly specified, but it is preferable to make the addition amount exhibiting the performance of each deodorant. Generally, 1-10 mass parts is preferable with respect to 100 mass parts of polyolefin resin of a polyolefin resin film. It is because the deodorizing function can be exhibited when the addition amount is 1 part by mass or more, and the cost can be suppressed when the addition amount is 10 parts by mass or less.

本実施の形態に用いる抗菌剤とは、臭気の原因となる菌の繁殖を抑制するものをいう。抗菌剤としては、ゼオライト、シリカゲル、珪酸塩系化合物、リン酸塩系化合物、溶解性ガラス等の担体に銀、銅、亜鉛等の金属を担持したもの、ホタテ貝殻を焼成した水酸化カルシウム(ホタテ貝殻の焼成物)を主成分とするもの等を用いることができる。中でもホタテ貝殻を焼成した水酸化カルシウム(ホタテ貝殻の焼成物)を主成分とする粉体は、消臭機能も併せ持つので有用である。その添加量は特に規定するものではないが、それぞれの抗菌剤の性能を発揮する添加量にすることが好ましい。一般的には、ポリオレフィン系樹脂フィルムのポリオレフィン系樹脂100質量部に対し、0.3〜3質量部であることが好ましい。添加量が0.3質量部以上であると抗菌機能を発揮可能であり、3質量部以下であるとコストを抑制できるためである。   The antibacterial agent used in this embodiment refers to an agent that suppresses the growth of bacteria that cause odor. Antibacterial agents include zeolite, silica gel, silicate-based compounds, phosphate-based compounds, a carrier made of soluble glass or the like carrying a metal such as silver, copper or zinc, or calcium hydroxide (scallop scallops) fired from scallop shells. The main component of which is a fired shell). Above all, powders mainly composed of calcium hydroxide (baked scallop shells) fired from scallop shells are useful because they also have a deodorizing function. The addition amount is not particularly specified, but it is preferable to make the addition amount exhibiting the performance of each antibacterial agent. Generally, it is preferable that it is 0.3-3 mass parts with respect to 100 mass parts of polyolefin resin of a polyolefin resin film. This is because the antibacterial function can be exhibited when the addition amount is 0.3 parts by mass or more, and the cost can be suppressed when the addition amount is 3 parts by mass or less.

本実施の形態の消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルム及び消臭剤及び抗菌剤を含まないポリオレフィン系樹脂フィルムに用いるポリオレフィン系樹脂フィルムとは、ポリプロピレン、ポリエチレン等のポリオレフィン系樹脂を基材樹脂とするフィルムである。   The polyolefin resin film used in the polyolefin resin film containing the deodorant or antibacterial agent and the polyolefin resin film not containing the deodorizer and antibacterial agent of the present embodiment is based on a polyolefin resin such as polypropylene or polyethylene. It is a film used as a material resin.

消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルム及び消臭剤及び抗菌剤を含まないポリオレフィン系樹脂フィルムに用いるポリオレフィン系樹脂としては、オレフィン系炭化水素の重合体又は共重合体であり、低密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、エチレン−ポリプロピレン共重合体、オレフィン系熱可塑性エラストマー等が挙げられ、更にエチレン−酢酸ビニル共重合体、エチレン−エチルアクリレート共重合体、エチレン−ジエン共重合体、エチレン−ジエン−3元共重合体等も用いることができる。なお、これらは単独あるいは2種類以上を組み合わせて使用することもできる。これらの中でもポリエチレンは、架橋ポリオレフィン系樹脂発泡体との加熱ロールによるラミネート作業性が良く、密着性も良好であり、積層発泡体の最表面(表層面)として風合いも良いことから好適である。   The polyolefin resin used in the polyolefin resin film containing the deodorant or antibacterial agent and the polyolefin resin film not containing the deodorizer and antibacterial agent is a polymer or copolymer of olefin hydrocarbon, and has a low density. Examples include polyethylene, high-density polyethylene, polypropylene, ethylene-polypropylene copolymer, and olefinic thermoplastic elastomer. Further, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, ethylene-diene copolymer, ethylene -Diene terpolymers can also be used. In addition, these can also be used individually or in combination of 2 or more types. Among these, polyethylene is preferred because it has good laminating workability with a heated roll with a crosslinked polyolefin resin foam, good adhesion, and good texture as the outermost surface (surface layer surface) of the laminated foam.

消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムの厚さは、50〜160μmであることが好ましい。厚さが50μm以上であると、架橋ポリオレフィン系樹脂発泡体との加熱ロールによるラミネート作業時にしわが発生し難く作業性が向上するためである。また、厚さが160μm以下であると、コストアップを抑制できるためである。   The thickness of the polyolefin resin film containing a deodorant or an antibacterial agent is preferably 50 to 160 μm. This is because when the thickness is 50 μm or more, wrinkles are unlikely to occur during laminating work with a heated roll with a crosslinked polyolefin resin foam, and workability is improved. Moreover, it is because a cost increase can be suppressed as thickness is 160 micrometers or less.

消臭剤及び抗菌剤を含まないポリオレフィン系樹脂フィルムの厚さは、消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムの厚さの50〜85%であることが好ましい。50%以上であると、そり抑制効果が発揮され、85%以下であると、消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムを設けた方の表層面との識別が容易であるとともにコストアップを抑制できるためである。また、消臭剤及び抗菌剤を含まないとは、消臭機能又は抗菌機能を発揮できないほど含有量が少ないことをいい、一般的に、消臭剤であれば、ポリオレフィン系樹脂フィルムのポリオレフィン系樹脂100質量部に対し1質量部未満であることをいい、抗菌剤であれば、ポリオレフィン系樹脂フィルムのポリオレフィン系樹脂100質量部に対し0.2質量部未満であることをいう。   The thickness of the polyolefin resin film that does not contain the deodorant and antibacterial agent is preferably 50 to 85% of the thickness of the polyolefin resin film that contains the deodorant or antibacterial agent. If it is 50% or more, the warp suppressing effect is exhibited, and if it is 85% or less, it is easy to distinguish from the surface layer on which the polyolefin resin film containing the deodorant or antibacterial agent is provided, and the cost is increased. It is because it can suppress. In addition, deodorant and antibacterial agent not containing means that the content is so small that the deodorant function or antibacterial function cannot be exhibited. Generally, if it is a deodorant, the polyolefin resin film of polyolefin resin film If it is an antibacterial agent, it means that it is less than 0.2 mass part with respect to 100 mass parts of polyolefin resin of a polyolefin resin film.

消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムを架橋ポリオレフィン系樹脂発泡体の片面(一方の面)のみに配置することにより、例えば、床に敷くマットとして用いる場合、消臭剤及び抗菌剤を含まないポリオレフィン系樹脂フィルムを配置した表層面を、消臭性や抗菌性は必要ないマットの裏面(マットの床側)とし、消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムを配置した表層面を、マットの表面(マットの床と反対側)とすることにより、より安価に生産することができる。   When a polyolefin resin film containing a deodorant or an antibacterial agent is disposed only on one side (one side) of the crosslinked polyolefin resin foam, for example, when used as a mat laid on the floor, the deodorant and the antibacterial agent The surface layer on which the polyolefin resin film containing no deodorant or antibacterial agent is placed on the back surface of the mat that does not require deodorant or antibacterial properties. By making the surface of the mat (the side opposite to the mat floor), it can be produced at a lower cost.

消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムと、消臭剤及び抗菌剤を含まないポリオレフィン系樹脂フィルムとは、熱膨張率が異なるため、これらのポリオレフィン系樹脂フィルムを、架橋ポリオレフィン系樹脂発泡体の両側に積層した場合は、積層発泡体に反りを生じる傾向がある。しかし、本実施の形態の積層発泡体では、消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムの厚さよりも、消臭剤及び抗菌剤を含まないポリオレフィン系樹脂フィルムの厚さを薄くすることにより、架橋ポリオレフィン系樹脂発泡体の両側に積層される、これらのポリオレフィン系樹脂フィルムの熱膨張率の差を小さくし、反りを低減することが可能になる。このため、緊急避難所用マット、スポーツマット等、平板状が要求される用途での反りの低減の要求に対応することができる。   Polyolefin resin films that contain deodorants or antibacterial agents and polyolefin resin films that do not contain deodorants and antibacterial agents have different coefficients of thermal expansion. When laminated on both sides of the body, the laminated foam tends to warp. However, in the laminated foam of the present embodiment, the thickness of the polyolefin resin film not containing the deodorant and the antibacterial agent is made thinner than the thickness of the polyolefin resin film containing the deodorant or the antibacterial agent. It is possible to reduce the difference in thermal expansion coefficient between these polyolefin resin films laminated on both sides of the crosslinked polyolefin resin foam and to reduce the warpage. For this reason, the request | requirement of the reduction | decrease of the curvature in the use for which flat form is requested | required, such as an emergency shelter mat and a sports mat, can be responded.

以上述べたとおり、本実施の形態によれば、ポリオレフィン系樹脂を用いた消臭性や抗菌性を有する積層発泡体をコスト的に優位に、且つマット等平板状で使用するのに有害なマットの反りを低減可能な形で容易に提供することができる。   As described above, according to the present embodiment, a mat that is detrimental to use in the form of a flat plate such as a mat is advantageous in terms of cost and a defoaming and antibacterial laminated foam using polyolefin resin. Can be easily provided in a form that can reduce the warpage.

(変形例1)
本実施の形態の積層発泡体において、その表層面の片面又は両面にエンボスを形成してもよい。ここで、表層面とは、架橋ポリオレフィン系樹脂発泡体とポリオレフィン系樹脂フィルムとを積層した積層発泡体の全体としての最表面のことをいう。このように、積層発泡体の表層面にエンボスを形成する方法としては、架橋ポリオレフィン系樹脂発泡体の一方の面又は他方の面に配置するポリオレフィン系樹脂フィルムにエンボス加工を施すことで実現できる。エンボスとは、文字状又は模様状の凹凸のことをいう。また、エンボス加工とは、エンボスを形成する加工のことをいい、例えば、架橋ポリオレフィン系樹脂フィルムと架橋ポリオレフィン系樹脂発泡体とを加熱ロールでラミネートするときに、エンボス加工した加熱ロールを用いることで容易に行うことができる。
(Modification 1)
In the laminated foam of the present embodiment, embossing may be formed on one surface or both surfaces of the surface layer surface. Here, the surface layer surface means the outermost surface as a whole of the laminated foam obtained by laminating the cross-linked polyolefin resin foam and the polyolefin resin film. Thus, as a method of forming emboss on the surface of the laminated foam, it can be realized by embossing the polyolefin resin film disposed on one side or the other side of the cross-linked polyolefin resin foam. Embossing refers to unevenness in the form of letters or patterns. Moreover, embossing means the process which forms embossing, for example, when laminating a cross-linked polyolefin resin film and a cross-linked polyolefin resin foam with a heat roll, it is possible to use an embossed heat roll. It can be done easily.

積層発泡体の表層面に形成したエンボスによって、凹凸模様による意匠性向上、あるいはエンボス模様による滑り止め機能を付加することができる。特には、床に敷くマットに適用する場合の裏面側(マットの床側)にエンボスを形成すると、例えば、緊急避難所となる体育館等の床に敷いた時の滑り防止になり、有用である。   By embossing formed on the surface of the laminated foam, it is possible to add a design improvement by the uneven pattern or an anti-slip function by the embossed pattern. In particular, when embossing is formed on the back side (mat floor side) when applied to mats laid on the floor, for example, it is useful for preventing slipping when laid on the floor of a gymnasium or the like as an emergency shelter. .

(変形例2)
本実施の形態の積層発泡体において、消臭剤又は抗菌剤を含む厚さ50〜160μmのポリオレフィン系樹脂フィルムからなる表層面に、印刷用インクによる模様を配置してもよい。印刷用インクによる模様を形成する方法としては、例えば、インクジェットプリンタを用いて、UV(Ultraviolet)硬化型の印刷用インクを、積層発泡体表層面に模様を形成するように転写した後、UVを照射して硬化する方法が挙げられる。
(Modification 2)
In the laminated foam of the present embodiment, a pattern made of printing ink may be arranged on the surface layer composed of a polyolefin resin film having a thickness of 50 to 160 μm containing a deodorant or an antibacterial agent. As a method for forming a pattern with printing ink, for example, using an inkjet printer, UV (ultraviolet) curable printing ink is transferred to form a pattern on the surface of the laminated foam, and then UV is transferred. There is a method of curing by irradiation.

このように、積層発泡体の表層面に模様があることにより、消臭性や抗菌性を発現する表層面を容易に識別でき、デザイン性を付与できるとともに、各地方自治体のロゴマーク、ゆるキャラ柄、民間企業の社名等を自由に印刷できるので、自治体や企業のPRにも繋がる効果が期待できる。   In this way, the surface of the laminated foam has a pattern, which makes it easy to identify the surface that expresses deodorant and antibacterial properties, as well as to provide design, as well as the logo mark of each local government, Since the company name of private companies can be printed freely, it can be expected to have an effect on PR of local governments and companies.

次に、芯材として、実施例1と同じ架橋ポリオレフィン系樹脂発泡体を準備し、この芯材のそれぞれの面に、実施例1と同様にして、上記で準備したポリオレフィン系樹脂フィルムを配置し、熱ラミネート機により積層して積層発泡体を得た。   Next, as the core material, the same crosslinked polyolefin resin foam as in Example 1 was prepared, and the polyolefin resin film prepared above was disposed on each surface of the core material in the same manner as in Example 1. The laminated foam was obtained by laminating with a heat laminator.

得られた積層発泡体は、表1に諸性能を示すが、優れた消臭性を有するとともに、反りも少なく、マットとして使用するのに支障がなかった。   The obtained laminated foam showed various performances in Table 1, but had excellent deodorizing properties and little warpage, and had no trouble for use as a mat.

[実施例3]
消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムとして、消臭剤(東亞合成株式会社製、商品名:ケスモンTNS−120、平均粒径:7μm)を1質量%、抗菌剤(石塚硝子株式会社製,商品名:イオンピュア、「イオンピュア」は登録商標)を1質量%含有する厚さ100μmのポリエチレンフィルムを準備した。また、消臭剤及び抗菌剤を含まないポリオレフィン系樹脂フィルムとして、通常の厚さ70μmのポリエチレンフィルムを準備した。
[Example 3]
As a polyolefin resin film containing a deodorant or an antibacterial agent, 1% by mass of a deodorant (manufactured by Toagosei Co., Ltd., trade name: Kesmon TNS-120, average particle size: 7 μm), an antibacterial agent (Ishizuka Glass Co., Ltd.) A polyethylene film having a thickness of 100 μm containing 1% by mass of manufactured and trade name: Ion Pure, “Ion Pure” is a registered trademark) was prepared. Moreover, the normal polyethylene film of 70 micrometers in thickness was prepared as a polyolefin-type resin film which does not contain a deodorizer and an antibacterial agent.

次に、芯材として、実施例1と同じ架橋ポリオレフィン系樹脂発泡体を準備し、この芯材のそれぞれの面に、実施例1と同様にして、上記で準備したポリオレフィン系樹脂フィルムを配置し、熱ラミネート機により積層して積層発泡体を得た。   Next, as the core material, the same crosslinked polyolefin resin foam as in Example 1 was prepared, and the polyolefin resin film prepared above was disposed on each surface of the core material in the same manner as in Example 1. The laminated foam was obtained by laminating with a heat laminator.

得られた積層発泡体は、諸性能を表1に示す通り、優れた消臭性と抗菌性を有するとともに、反りも少なく、マットとして使用するのに支障がなかった。   As shown in Table 1, the obtained laminated foam had excellent deodorizing properties and antibacterial properties, had little warpage, and had no hindrance to use as a mat.

[実施例4]
消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムと、消臭剤及び抗菌剤を含まないポリオレフィン系樹脂フィルムとして、何れも実施例1と同じものを準備した。
[Example 4]
The same thing as Example 1 was prepared as the polyolefin resin film containing a deodorizer or an antibacterial agent, and the polyolefin resin film which does not contain a deodorizer and an antibacterial agent.

次に、芯材として、実施例1と同じ架橋ポリオレフィン系樹脂発泡体を準備し、この芯材のそれぞれの面に、実施例1と同様にして、上記で準備したポリオレフィン系樹脂フィルムを配置し、熱ラミネート機により積層して積層発泡体を得た。ただし、熱ラミネート時に片方のロールにエンボスを有するものを用いることにより、消臭剤及び抗菌剤を含まないポリオレフィンフィルム側にエンボスを形成した。   Next, as the core material, the same crosslinked polyolefin resin foam as in Example 1 was prepared, and the polyolefin resin film prepared above was disposed on each surface of the core material in the same manner as in Example 1. The laminated foam was obtained by laminating with a heat laminator. However, the embossing was formed on the polyolefin film side not containing the deodorant and the antibacterial agent by using one having embossing on one of the rolls at the time of thermal lamination.

得られた積層発泡体は、表1に諸性能を示すが、優れた抗菌性を有するとともに、マットとして使用したときの反りも少なかった。また、マットとして使用する際、床と接する面がエンボス模様を有することから滑り止め効果を付与することができるとともに、使用時にどちらを床と接する面にするかの判別がより容易になった。   The obtained laminated foam showed various performances in Table 1, but had excellent antibacterial properties and had little warpage when used as a mat. Further, when used as a mat, since the surface in contact with the floor has an embossed pattern, an anti-slip effect can be imparted, and it becomes easier to determine which surface is in contact with the floor during use.

[実施例5]
実施例1と同様の構成において、ホタテ貝殻を焼成した水酸化カルシウム粉末のポリエチレンフィルムへの添加量を0.2質量%に変更した積層発泡体を作製した。得られた積層発泡体の諸性能を表1に示すが、消臭性及び抗菌性ともに期待したほどではないが性能が発現した。
[Example 5]
In the same configuration as in Example 1, a laminated foam was produced in which the addition amount of calcium hydroxide powder obtained by baking scallop shells to the polyethylene film was changed to 0.2% by mass. The various performances of the obtained laminated foam are shown in Table 1, but the performance was exhibited although not as much as expected for both deodorization and antibacterial properties.

[比較例1]
消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムとして、実施例2で用いた消臭剤を含有するポリエチレンフィルムを準備した。
[Comparative Example 1]
A polyethylene film containing the deodorant used in Example 2 was prepared as a polyolefin resin film containing a deodorant or an antibacterial agent.

次に、芯材として、実施例1と同じ架橋ポリオレフィン系樹脂発泡体を準備し、この芯材の一方の面に、準備した消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムを配置したが、他方の面にはポリオレフィン系樹脂フィルムを配置せずに、熱ラミネート機により積層して積層発泡体を得た。   Next, as the core material, the same crosslinked polyolefin resin foam as in Example 1 was prepared, and the prepared polyolefin resin film containing the deodorant or antibacterial agent was disposed on one surface of the core material. A laminated foam was obtained by laminating with a heat laminator without placing a polyolefin resin film on the other surface.

得られた積層発泡体の諸性能を表1に示すが、マットとして使用する場合、反りが大きく、消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムを配置した表層面側が凸面になるため、無理に反りを矯正すると、消臭剤又は抗菌剤を含むポリオレフィン系樹脂フィルムを配置した表層面にしわが発生し、実用上好ましいものではなかった。   Various performances of the obtained laminated foam are shown in Table 1, but when used as a mat, the warp is large, and the surface side of the polyolefin resin film containing the deodorant or antibacterial agent becomes convex, which is impossible. When the warp was corrected, wrinkles were generated on the surface layer on which the polyolefin resin film containing the deodorant or antibacterial agent was disposed, which was not preferable in practice.

以上述べたように、実施例に示した積層発泡体は片面の表層面に消臭性や抗菌性を有するとともに、マット等として使用する場合の反りを低減することができるものである。
