[Deodorants]
The deodorant preferably contains one or more selected from the group consisting of an inorganic odor decomposing agent and an inorganic porous body. When the filth is human waste, the odorous components contain hydrogen sulfide and ammonia, and the above-mentioned deodorant can efficiently deodorize these odorous components.

The powdered metal-supported inorganic oxide is mixed with the raw material metal oxide, phosphorus compound, etc., melted and homogenized by the same method as for making general-purpose glass such as bottle glass, cooled, and then pulverized. It can be obtained by making it into a powder and supporting a metal salt. Alternatively, the metal salts may be premixed together before the raw materials are melted.
（無機多孔体）
無機多孔体は、その表面に多数の細孔を有する物質であり、例えば、活性白土や活性化ベントナイト、ゼオライト、ジルコニウム化合物、二酸化ケイ素、ケイ酸塩、活性炭、チタニア、燐酸カルシウム等の無機燐酸塩、アルミナ、水酸化アルミニウム、水酸化マグネシウム、及びこれらの混合物が挙げられる。

(Inorganic porous body)
The inorganic porous body is a substance having a large number of pores on its surface, and is, for example, an inorganic phosphate such as activated clay, activated bentonite, zeolite, zirconium compound, silicon dioxide, silicate, activated carbon, titania, and calcium phosphate. , Alumina, aluminum hydroxide, magnesium hydroxide, and mixtures thereof.
Activated clay is a type of clay that is porous, has a large specific surface area, and has excellent adsorptivity, and is obtained by heat-treating naturally-produced acidic clay containing montmorillonite as the main component with an inorganic acid such as sulfuric acid or hydrochloric acid.
Among the above, activated clay, activated bentonite, and zeolite are preferably used from the viewpoints of odor adsorption performance, having a porous state with pore sizes effective for the molecular size and cluster size of the odorous substance, and safety.
活性白土は比表面積の大きいものが好ましく、比表面積に特に制限は無いが、比表面積５０〜４００ｍ2／ｇのものが入手し易い。ｐＨ（５％サスペンジョン）は２．５〜９が好ましく、３〜７がより好ましい。 The activated clay preferably has a large specific surface area, and the specific surface area is not particularly limited, but one having a specific surface area of 50 to 400 m 2 / g is easily available.

ゼオライトは、ＳｉＯ2／Ａｌ2Ｏ3を主成分とする物質であり、一般的にＳｉＯ2／Ａｌ2Ｏ3のモル比が高い程、疎水性が高くなり、本発明においては、ＳｉＯ2／Ａｌ2Ｏ3のモル比が、３０／１〜８０００／１の疎水性ゼオライトが好ましい。
疎水性ゼオライトは、シートまたはシート材料が２３０℃以上に晒された場合であっても、臭気吸着能を喪失することは無く、臭気物質の吸着による消臭効果を発揮することができる。
疎水性ゼオライトは、疎水性である為に、極性の高い水分子等は吸着し難く、逆に極性の低い、臭い分子、疎水性ガス、親油性ガス（溶剤系ガスも含む）との親和性が高く、これらを吸着し易い。更に、ゼオライト表面に存在する、Ｃａ、Ｎａ、Ｋ等のアルカリ金属、アルカリ土類金属の効果によりゼオライト表面は塩基性を示し、酸性ガスを中和反応によって吸着し易い。
Zeolites are substances mainly composed of SiO 2 / Al 2 O 3, generally higher molar ratio of SiO 2 / Al 2 O 3, the higher the hydrophobicity, in the present invention, SiO 2 / Hydrophobic zeolite having a molar ratio of Al 2 O 3 of 30/1 to 8000/1 is preferable.
Hydrophobic zeolite does not lose its odor adsorbing ability even when the sheet or sheet material is exposed to 230 ° C. or higher, and can exert a deodorizing effect by adsorbing odorous substances.
Since hydrophobic zeolite is hydrophobic, it is difficult to adsorb highly polar water molecules, etc., and conversely, it has an affinity with low-polarity odor molecules, hydrophobic gases, and lipophilic gases (including solvent-based gases). Is high and it is easy to adsorb these. Further, the zeolite surface is basic due to the effects of alkali metals such as Ca, Na and K and alkaline earth metals existing on the zeolite surface, and acid gas is easily adsorbed by a neutralization reaction.
＜防汚層＞
防汚層は、防汚性を有する層であり、熱可塑性樹脂を含有する。
そして、防汚層の水蒸気透過率は、２０００ｇ／ｍ2／ｄａｙ以下が好ましい。上記範囲よりも大きい水蒸気透過率だと、防汚層を臭気や汚水が透過してしまう虞がある。下限値は低いほど好ましく、０ｇ／ｍ2／ｄａｙが最も好ましい。
また、防汚層は、ヒートシール性を有していてもよく、その場合には、ヒートシール性を有する熱可塑性樹脂を含有することが好ましい。
防汚層は、１層構成であっても、構成が同一または異なる２層以上で構成されていてもよい。例えば、ヒートシール性の異なる３層から構成されていてもよい。特に、防汚層を防汚フィルムから形成する場合には、防汚フィルムの両面にヒートシール性の高い層を積層しておくと積層時の接着性に優れることから防汚層の形成を容易に行うことができ、且つ、防汚層が表面層である場合には、ヒートシール性に優れた消臭防汚シート材料を得ることができる。
<Anti-fouling layer>
The antifouling layer is a layer having antifouling properties and contains a thermoplastic resin.
The water vapor transmittance of the antifouling layer is preferably 2000 g / m 2 / day or less. If the water vapor permeability is larger than the above range, odor or sewage may permeate through the antifouling layer. The lower the lower limit, the more preferable, and 0 g / m 2 / day is most preferable.
Further, the antifouling layer may have a heat-sealing property, and in that case, it is preferable to contain a thermoplastic resin having a heat-sealing property.
The antifouling layer may be composed of one layer, or may be composed of two or more layers having the same or different configurations. For example, it may be composed of three layers having different heat seal properties. In particular, when the antifouling layer is formed from an antifouling film, it is easy to form the antifouling layer because the adhesiveness at the time of laminating is excellent if layers having high heat-sealing properties are laminated on both sides of the antifouling film. When the antifouling layer is a surface layer, a deodorant antifouling sheet material having excellent heat-sealing properties can be obtained.
［防汚層中の熱可塑性樹脂］
防汚層において、上記のような水蒸気透過率を示したり、防汚性やヒートシール性に優れたりする熱可塑性樹脂としては、ポリオレフィン系樹脂が好ましく、ポリオレフィン系の樹脂の中でもポリエチレン系樹脂がより好ましく、ポリエチレン系の樹脂の中でもＬＬＤＰＥまたはＬＤＰＥが更に好ましい。
[Thermoplastic resin in the antifouling layer]
Polyolefin-based resins are preferable as thermoplastic resins having the above-mentioned water vapor permeability and excellent antifouling properties and heat-sealing properties in the antifouling layer, and polyethylene-based resins are more preferable among polyolefin-based resins. Among the polyethylene-based resins, LLDPE or LDPE is more preferable.
