【発明の属する技術分野】
本発明は、紫外線遮蔽剤及びこれを用いた紫外線遮蔽加工製品に関する。特に、本発明は、抗菌抗カビ性を有する紫外線遮蔽剤及び紫外線遮蔽加工製品に関する。
【０００２】
【従来の技術】
近年、地球的規模でオゾン層の破壊が進行しており、地表への紫外線到達量の増加による人の皮膚等への悪影響が危惧され、衣料にも一部紫外線遮蔽加工がなされている。そして、かかる目的には、紫外線遮蔽加工剤としては、酸化亜鉛や酸化チタン等が使用されている。
【０００３】
また、院内感染や食中毒等の菌由来の問題や真菌症やカビによるアレルギー等のカビ由来の問題も多発しており、これに呼応して抗菌抗カビ加工を施した製品が上市されている。
しかしながら、抗菌性、抗カビ性及び紫外線遮蔽効果の要求の全てを満たす化合物は未だ見出されておらず、これらの効果の全てを付与する場合には、抗菌剤、抗カビ剤及び紫外線遮蔽剤の３つの薬剤を併用する必要があるが、現実にはコストが高くつくことや各薬剤同士の相溶性が不良であったりする等の問題があって、ほとんど実用化されていない。
【０００４】
【発明が解決しようとする課題】
本発明は、抗菌剤、抗カビ剤及び紫外線遮蔽剤の３つの薬剤併用に伴うコスト高、管理の煩雑さ、薬剤同士の相溶性不良等による種々の問題を解消することのできる、簡便な薬剤を提供することを目的とてなされたものである。
【０００５】
【課題を解決するための手段】
本発明者らは、上記の課題を解決するため鋭意研究を重ねた結果、抗菌抗カビ性のあるビス（１−ヒドロキシ−２（１Ｈ）ピリジンチオネート−Ｏ，Ｓ）−（Ｔ−４）の金属塩を微粒子化することにより紫外線の遮蔽効果が増すことを見出し、この知見に基づき本発明を完成させた。
【０００６】
すなわち、本発明は、最大粒子径が５μｍ以下に微粒子化されたビス（１−ヒドロキシ−２（１Ｈ）ピリジンチオネート−Ｏ，Ｓ）−（Ｔ−４）の金属塩１〜６０重量％の水分散物からなる、抗菌抗カビ性を有する紫外線遮蔽剤を提供する。
【０００７】
【発明の実施の形態】
本発明に用いるビス（１−ヒドロキシ−２（１Ｈ）ピリジンチオネート−Ｏ，Ｓ）−（Ｔ−４）の金属塩に特に制限はないが、好ましくは亜鉛塩または銅塩である。
本発明に用いるビス（１−ヒドロキシ−２（１Ｈ）ピリジンチオネート−Ｏ，Ｓ）−（Ｔ−４）の金属塩は、その最大粒子径を５μｍ以下に調整することを必要とする。最大粒子径が５μｍ以上であると紫外線遮蔽効果が弱くなる傾向にある。この微粒子化を行う際には、界面活性剤をビス（１−ヒドロキシ−２（１Ｈ）ピリジンチオネート−Ｏ，Ｓ）−（Ｔ−４）の金属塩に対して１〜５０重量％加えた水中に、ビス（１−ヒドロキシ−２（１Ｈ）ピリジンチオネート−Ｏ，Ｓ）−（Ｔ−４）の金属塩１〜６０重量％を撹拌機を用いて予備分散し、その後サンドグラインダーのような微粒子化機にて最大粒子径が５μｍ以下になるように微粒子化することが好ましい。。この時使用される界面活性剤としては、例えば、ポリオキシアルキレンアルキルエーテル、ポリオキシアルキレンアルキルアミンやポリオキシアルキレンスチレン化フェニルエーテルなどの非イオン界面活性剤、好ましくはこの非イオン界面活性剤のＨＬＢが１５以上のものや、ポリオキシアルキレンアルキルエーテルスルホン酸塩、ポリオキシアルキレンスチレン化フェニルエーテルスルホン酸塩や多環系複素環型スルホン酸塩などのアニオン界面活性剤が挙げられる。微粒子化によって紫外線遮蔽効果が向上するとともに、紫外線遮蔽剤の沈降現象が抑制でき、もし沈降した場合でも固化することなく、容易に再分散復元が可能となる。また、従来より粉体の水分散物で問題となっていた処理現場での物理的衝撃による発粉現象や他薬剤との相溶性の不良によるスカム発生等の種々の問題に対しても改善が可能となる。
【０００８】
本発明の紫外線遮蔽剤による処理の対象としては、繊維製品やコーティング樹脂組成物が挙げられる。繊維製品としては、ポリエステル、ナイロン、アクリルなどの合成繊維、綿、麻、ウールなどの天然繊維や合成繊維と天然繊維の複合繊維があり、繊維の形態としては糸、布帛、編物や不織布などのあらゆる繊維製品が挙げられる。特に、白い繊維製品への使用に当たっても変色等の問題がないものである。また、コーティング樹脂組成物としては、アクリル樹脂エマルジョン、ウレタン樹脂エマルジョン、酢酸ビニルエマルジョン等が挙げられる。
【０００９】
本発明の紫外線遮蔽剤の繊維製品への加工方法としては、微粒子化により安定な分散状態が得られていて、パッディング処理、浸漬処理、染浴同浴処理やコーティングなどのあらゆる後加工工程での使用が可能である。
本発明の紫外線遮蔽剤を付与された繊維製品に洗濯に対する耐久性が要求される場合には、バインダー樹脂を併用することにより対応が可能となる。この際に用いられるバインダー樹脂としては、例えば、Ｎ−メチロール系、グリオキザール系、ウレタン系、ポリエステル系、アクリル系、エポキシ系やポリビニルアルコール系等の従来より用いられている樹脂が挙げられ、要求される洗濯に対する耐久性や風合いなど考慮し、バインダー樹脂の選択と使用量を調整することにより目的の耐久性を得ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an ultraviolet shielding agent and an ultraviolet shielding processed product using the same. In particular, the present invention relates to an ultraviolet shielding agent having antibacterial and antifungal properties and an ultraviolet shielding processed product.
[0002]
[Prior art]
In recent years, the destruction of the ozone layer is progressing on a global scale, and there is a concern that an increase in the amount of ultraviolet rays reaching the surface of the earth may have an adverse effect on human skin and the like. For this purpose, zinc oxide, titanium oxide or the like is used as an ultraviolet shielding agent.
[0003]
In addition, problems caused by fungi such as hospital-acquired infections and food poisoning, and problems caused by fungi such as mycosis and allergy due to mold have frequently occurred.
However, a compound satisfying all the requirements of antibacterial properties, antifungal properties and ultraviolet shielding effects has not been found yet, and when all of these effects are imparted, antibacterial agents, antifungal agents and ultraviolet shielding agents are required. These three drugs need to be used in combination, but in reality there are problems such as high cost and poor compatibility between the drugs, and thus they are hardly practically used.
[0004]
[Problems to be solved by the invention]
The present invention is a simple drug which can eliminate various problems caused by high cost, complicated management, poor compatibility between drugs, etc., which are caused by the combination of three drugs, an antibacterial agent, an antifungal agent and an ultraviolet ray shielding agent. The purpose of this is to provide.
[0005]
[Means for Solving the Problems]
The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that bis (1-hydroxy-2 (1H) pyridinethionate-O, S)-(T-4) having antibacterial and antifungal properties. It has been found that the effect of blocking ultraviolet rays is increased by making the metal salt into fine particles, and the present invention has been completed based on this finding.
[0006]
That is, the present invention relates to a method of preparing 1 to 60% by weight of a metal salt of bis (1-hydroxy-2 (1H) pyridinethionate-O, S)-(T-4) having a maximum particle diameter of 5 μm or less . Provided is an ultraviolet ray shielding agent comprising an aqueous dispersion and having antibacterial and antifungal properties.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
The metal salt of bis (1-hydroxy-2 (1H) pyridinethionate-O, S)-(T-4) used in the present invention is not particularly limited, but is preferably a zinc salt or a copper salt.
The metal salt of bis (1-hydroxy-2 (1H) pyridinethionate-O, S)-(T-4) used in the present invention needs to have its maximum particle size adjusted to 5 μm or less. When the maximum particle diameter is 5 μm or more, the ultraviolet shielding effect tends to be weak. When this micronization is performed, a surfactant is added in an amount of 1 to 50% by weight based on the metal salt of bis (1-hydroxy-2 (1H) pyridinethionate-O, S)-(T-4). In water, 1 to 60% by weight of a metal salt of bis (1-hydroxy-2 (1H) pyridinethionate-O, S)-(T-4) is predispersed by using a stirrer, and then, like a sand grinder. It is preferable to make the particles into a fine particle by using a fine particle generator so that the maximum particle diameter becomes 5 μm or less. . As the surfactant used at this time, for example, a nonionic surfactant such as polyoxyalkylene alkyl ether, polyoxyalkylene alkylamine and polyoxyalkylene styrenated phenyl ether, preferably HLB of this nonionic surfactant And anionic surfactants such as polyoxyalkylene alkyl ether sulfonates, polyoxyalkylene styrenated phenyl ether sulfonates and polycyclic heterocyclic sulfonates. The fine particle formation improves the ultraviolet shielding effect and suppresses the sedimentation phenomenon of the ultraviolet shielding agent. Even if the sedimentation occurs, redispersion and restoration can be easily performed without solidification. In addition, various problems such as powdering due to physical impact at the treatment site and scum due to poor compatibility with other chemicals, which have been problems with water dispersions of powders, have been improved. It becomes possible.
[0008]
The object to be treated with the ultraviolet shielding agent of the present invention includes textile products and coating resin compositions. As textile products, there are synthetic fibers such as polyester, nylon, and acrylic; natural fibers such as cotton, hemp, and wool; and composite fibers of synthetic fibers and natural fibers.The fiber forms include yarns, fabrics, knits, and nonwoven fabrics. All textile products are included. In particular, there is no problem such as discoloration when used for white fiber products.
