- the composition described in Patent Document 1 is composed of a dispersion liquid in which silver nanoparticles are dispersed in a solvent, and is antibacterial by contacting the dispersion liquid on the substrate surface to which antibacterial property should be imparted. Since it is to be imparted, the fixing property to the substrate is not sufficient, and the durability of the effect is not yet satisfactory.
- antibacterial performance is imparted to the resin molded body itself by combining with the resin, instead of applying the above substance to a molded body molded in advance as in Patent Document 1. This is advantageous in terms of productivity and sustainability of effects.
- an expensive substance such as silver is equal to or higher than the conventional one with a content less than the conventional blending amount. It is required to exhibit antibacterial performance. That is, in the antibacterial resin composition, in order to obtain an antibacterial effect, it is necessary that metal ions such as silver act on the bacteria. In other words, metal ions such as silver ions are required to elute from the resin composition, but it is difficult to efficiently elute silver present in the molded article made of the antibacterial resin composition to the surface of the molded article. In the conventional antibacterial resin composition, there is a problem that the silver compound present in the molded body cannot be effectively used. Further, since the eluted metal ions, particularly silver, are unstable in the ionic state, they immediately became metal silver or a silver compound, and the antibacterial effect could not be obtained efficiently.

Abstract
Description
例えば、下記特許文献1には、溶媒と、銀ナノ粒子と、安定剤とを含む組成物が記載されており、また下記特許文献2には、有機銀系抗菌剤と有機系抗菌剤とを含有する抗菌性組成物が記載されている。
また特許文献2及び3に記載された組成物においては、特許文献1のように予め成形された成形体に上記物質を施すのではなく、樹脂との組み合わせにより樹脂成形体自体に抗菌性能を付与することが可能であり、生産性や効果の持続性等の点で有利である。
すなわち、抗菌性樹脂組成物において、抗菌効果を得るには銀等の金属イオンが菌に作用することが必要である。つまり、樹脂組成物から銀イオン等の金属イオンが溶出することが求められるが、抗菌性樹脂組成物から成る成形体内部に存在する銀を成形体表面に効率よく溶出させることが困難であったため、従来の抗菌性樹脂組成物においては、成形体内部に存在する銀化合物を有効に利用することができないという問題があった。
また、溶出した金属イオン、特に銀はイオン状態では不安定なため、すぐに金属銀や銀化合物となってしまい効率よく抗菌効果が得られなかった。
本発明の他の目的は、利用開始初期のみならず、経時後でも優れた抗菌性能を有する抗菌性樹脂組成物を提供することである。
かかる抗菌性樹脂組成物においては、熱可塑性樹脂又は熱硬化性樹脂100重量部当り、前記金属イオンを担持した金属担持化合物を0.001乃至10重量部、前記化合物(2)を0.001乃至30重量部の量で含有することが好適である。
本発明によれば更にまた、上記抗菌性樹脂組成物を、混合加熱し、成形してなる抗菌性樹脂成形体が提供される。
また本発明の第二及び第三の態様の抗菌性樹脂組成物においては、Ag,Cu,Zn,Co,Niから選ばれる少なくとも1種の脂肪酸金属塩、又はAg,Cu,Zn,Co,Niから選ばれる少なくとも1種の金属イオンを担持した金属担持化合物の何れかを、化合物(2)と組合せで、熱可塑性樹脂又は熱硬化性樹脂に配合することにより、金属化合物(1)を熱可塑性樹脂又は熱硬化性樹脂に直接配合した場合と同様の抗菌効果を有する樹脂成形体或いは塗膜を提供することができる。
すなわち、上記脂肪酸金属塩又は金属担持化合物を、化合物(2)と共に樹脂中に存在させることによって、脂肪酸金属塩又は金属担持化合物から溶出された金属イオンが、化合物(2)と一緒に存在することによって安定化し、金属イオンと化合物(2)が樹脂内部から同時に溶出することで、優れた抗菌性能を発現できる。
また樹脂組成物の内部に存在する金属化合物(1)、化合物(2)、及び脂肪酸金属塩又は金属担持化合物を効率よく使用することができるため、初期は表面に存在する化合物が抗菌性能を発現し、経時後、樹脂組成物内部に存在する化合物が表面に移行して抗菌性能を発現するため、長期にわたって抗菌性能を発現することも可能である。
すなわち、本発明の抗菌性樹脂組成物から成るフィルム(実施例1~16)においては、ステアリン酸銀、フタラゾン銀、ベンゾトリアゾール銀、1,8―ナフタルイミド銀、市販の抗菌剤を配合した樹脂組成物から成るフィルム(比較例1~20)では満足する抗菌効果を得ることができなかった、化合物(金属化合物(1)、或いは脂肪酸金属塩又は金属担持化合物及び化合物(2)の組み合わせ)の配合量でも、優れた抗菌効果が得られており、樹脂組成物中から効率よく銀イオンが溶出し、優れた抗菌性能を有していることが明らかである。
またこの実施例の結果から、フタラゾン銀(比較例7~10)、ベンゾトリアゾール銀(比較例11~14)では、実施例と同様の効果が得られていないことから、本発明においては、金属化合物(1)及び化合物(2)中の五員環とベンゼン環から成る部分が、銀イオンの安定化に効果があり、ベンゼン環と-CO-N-を有する五員環から成る複素環を有するものであることが、抗菌性能を向上させる上で重要であることがわかる。
本発明の第一の態様で用いられる上記式(1)で表わされる具体的な金属化合物としては、これに限定されないが、以下のものを挙げることができる。尚、下記式においてAgに代えてCu,Zn,Co,Niを例示することもできる。
図1は、種々の銀含有化合物についてJIS Z 7260-107に準拠して行った1-octanol中または水中への各種銀化合物の銀濃度測定結果を示す図である。この結果によると、サッカリン銀は、ステアリン酸銀や、フタラゾン銀、ベンゾトリアゾール銀に比して、親水性及び親油性のいずれも優れていることが明らかであり、後述する実施例の結果とも合致して、抗菌性樹脂組成物として優れた性能を示すことが明らかである。
上記式(2)で表される化合物(2)としては、これに限定されないが、以下のものを挙げることができる。尚、下記式においてNaに代えて、K又はHである化合物を例示することもできる。
本発明の第二の態様において、化合物(2)との組合せで使用される脂肪酸金属塩としては、Ag,Cu,Zn,Co,Niから選ばれる少なくとも1種の金属の脂肪酸金属塩であり、脂肪酸としては、ミリスチン酸,ステアリン酸,オレイン酸,パルミチン酸,n-デカン酸,パラトイル酸,コハク酸,マロン酸,酒石酸,リンゴ酸,グルタル酸,アジピン酸、酢酸等を挙げることができ、中でもステアリン酸を好適に使用することができる。最も好適な脂肪酸金属塩としては、ステアリン酸銀を挙げることができる。
尚、脂肪酸金属塩と化合物(2)の組合せにおいては、用いる脂肪酸金属塩及び化合物(2)の種類によっては、これらの化合物が反応して、化合物(2)が脂肪酸金属塩の銀等の金属に配位して金属化合物(1)が生成し、銀イオンが安定化して、金属化合物(1)を直接配合した場合と同様の構成が得られる場合もある。
本発明の第三の態様において、化合物(2)との組合せで使用される、金属イオンを担持した金属担持化合物としては、Ag,Cu,Zn,Co,Niから選ばれる少なくとも1種の金属の金属イオンを担持した、無機イオン交換体,無機系吸着剤等を挙げることができる。
金属イオンを担持した金属担持化合物は、それ自体一般的に抗菌剤として使用されており、金属イオンが溶出することで抗菌作用を発現するものであるが、本発明においては、樹脂中にかかる金属イオンと共に、化合物(2)が存在することにより金属イオンが安定化し、金属イオンと化合物(2)が樹脂内部から同時に溶出することで、優れた抗菌性能を発現できると考えられる。
無機イオン交換体としては、ゼオライト、リン酸ジルコニウム、リン酸カルシウム、溶解性ガラス、珪酸アルミン酸マグネシウム、珪酸カルシウム、ハイドロタルサイト、カルシウムアパタイト等を挙げることができ、無機系吸着剤としては、シリカゲル、活性アルミナ等を挙げることができるが、本発明においては特に、ゼオライト、リン酸ジルコニウムを好適に使用することができる。
本発明の抗菌性樹脂組成物に使用し得る熱可塑性樹脂としては、従来公知のものをすべて使用でき、例えば、低-,中-,高-密度ポリエチレン、線状低密度ポリエチレン、線状超低密度ポリエチレン、アイソタクティックポリプロピレン、シンジオタクティックポリプロピレン、プロピレン-エチレン共重合体、ポリブテン-1、エチレン-ブテン-1共重合体、プロピレン-ブテン-1共重合体、エチレン-プロピレン-ブテン-1共重合体等のオレフィン樹脂、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレンナフタエート等のポリエステル樹脂、ナイロン6、ナイロン6,6、ナイロン6,10等のポリアミド樹脂、ポリカーボネート樹脂等を挙げることができる。
本発明においては特に、ポリエチレン又はポリプロピレンを好適に用いることができる。
本発明の抗菌性樹脂組成物に使用し得る熱硬化性樹脂としては、従来公知のものをすべて使用することができ、例えば、フェノール樹脂、エポキシ樹脂、ウレタン樹脂、メラミン樹脂、尿素樹脂、アルキド樹脂、不飽和ポリエステル樹脂、シリコーン樹脂等を挙げることができる。
本発明においては特に、シリコーン樹脂を好適に用いることができる。
本発明の第一の態様の抗菌性樹脂組成物においては、金属化合物(1)を熱可塑性樹脂又は熱硬化性樹脂100重量部当り、0.001乃至10重量部、特に0.005乃至1重量部の量で配合することが好ましく、上記範囲よりも金属化合物(1)の量が少ないと十分な抗菌効果を得ることができない。一方上記範囲よりも多くすることによって、より抗菌効果を高くすることが可能であるが、経済性及び成形性の点で好ましくない。
尚、抗菌とは、製品の表面における細菌の増殖を抑制する状態を示し、抗菌効果はJIS Z 2801もしくはJIS L 1902に記載されている抗菌活性値もしくは静菌活性値で判断される抗菌加工製品の効果である。
また本発明の第二及び第三の態様の抗菌性樹脂組成物においては、脂肪酸金属塩或いは金属担持化合物を、熱可塑性樹脂又は熱硬化性樹脂100重量部当り、0.001乃至10重量部、特に0.005乃至1重量部、化合物(2)を熱可塑性樹脂又は熱硬化性樹脂100重量当り、0.001乃至30重量部、特に0.02乃至10重量部の量で配合することが好ましい。
また本発明の抗菌性樹脂組成物においては、その用途に応じて、それ自体公知の各種配合剤、例えば、充填剤、可塑剤、レベリング剤、増粘剤、減粘剤、安定剤、酸化防止剤、紫外線吸収剤、顔料等を公知の処方に従って配合することができる。
樹脂成形品への成形温度は、成形方法や用いる熱可塑性樹脂、金属化合物(1)或いは脂肪酸金属塩又は金属担持化合物及び化合物(2)の種類によって一概に規定できないが、用いる熱可塑性樹脂の成形可能な温度範囲であればよい。
また本発明の抗菌性熱可塑性樹脂組成物は、それ単独で樹脂成形品を構成することができるが、他の樹脂との組み合わせで多層構造とすることもできる。
塗膜、樹脂成形品等への加熱硬化条件は、用いる熱硬化性樹脂、金属化合物(1)、或いは脂肪酸金属塩又は金属担持化合物及び化合物(2)の種類によって一概に規定できないが、用いる熱硬化性樹脂の硬化温度及び硬化時間を基準して設定することができる。
ホモポリプロピレン(プライムポリマー社製 F-704NP)にサッカリン銀を重量で0.01%配合し、押出成形機設定温度180℃、Q(吐出量)/N(スクリュー回転数)=4/150=0.027の成形条件で2軸押出機((株)東洋精機製作所製)を用いて、押し出して厚み100μmのフィルムを作製した。
銀化合物の種類・配合量を表1のように変更した以外は実施例1と同様にしてフィルムを作成した。なお、表中の抗菌剤Aは、ジルコニウム系抗菌剤(商標:ノバロン(AQ1100) 東亞合成社製)を使用した。
シリコーン樹脂(モメンティブ・パフォーマンス・マテリアルズ・ジャパン合同会社製 YSR3022)にサッカリン銀を重量でそれぞれ0.01%、0.1%配合し、トルエンで全体を約5倍に希釈しよく攪拌混合した後に、触媒(モメンティブ・パフォーマンス・マテリアルズ・ジャパン合同会社製 YC6831)をシリコーン樹脂の重量で4%添加し、50℃で3時間静置して硬化させ、シリコーン膜を作製した。
抗菌試験方法はJIS Z 2801:2000抗菌加工製品―抗菌性試験方法に準じた。菌種は黄色ブドウ球菌(S.aureus)を用いた。無加工フィルムの培養後菌数から抗菌加工フィルムの培養後菌数を除した数の対数値を抗菌活性値とした。
添加量0.1wt%、0.01wt%共に抗菌活性値2.0以上の場合を○。添加量0.1wt%で抗菌活性値2.0以上、添加量0.01wt%で2.0未満の場合を△。添加量0.1wt%、0.01wt%共に抗菌活性値2.0未満の場合を×と判定した。
上記作製した実施例2、比較例4、8について銀の溶出性試験を行った。水50mL中に5cm×25cmのフィルム片を2枚投入し25℃18時間保管した。その後、水を発光分光分析装置(iCAP6500 Thermo Scientific製)にて銀の溶出量を測定した。測定した結果を図2に示した。図2の結果から、サッカリン銀を含有したフィルムはステアリン酸銀またはフタラゾン銀を含有したフィルムに比べて溶出量が高いことがわかる。
また本発明の抗菌性樹脂組成物においては、細菌、アレルゲン物質の他、真菌、アミノ酸配列によって特定の立体構造を持つ酵素、或いはDNAまたはRNA(核酸)と少数の蛋白分子からなる粒子状物質であるウィルス等の微小蛋白質も、有効に不活性化することができる。例えば、医療分野、生活用品分野、寝装分野、建材分野、電子工業分野、水処理分野等を挙げることができる。具体的には、病院等で使用される製品或いは医療用品、台所、浴室、洗面所等高温多湿の条件下で使用される製品、床、壁面、カーテン、カーペット、壁床用塗料、接着剤、目地剤等の住宅関連部材、空調機器、織布、不織布等の繊維製品、マスク、フィルター等の濾過部材等の製品に好適に使用することができる。
