Description
【０００１】
【発明の属する技術分野】
本発明は、抗かび性ガラスと、これを含む樹脂組成物に関するものである。
【０００２】
【従来の技術】
歯ブラシ、石鹸入れ、たらい、洗面台、浴槽等の樹脂製品は、長時間高湿の条件下で使用されるので細菌やかびが増殖しやすい。細菌やかびの増殖をおさえるために、従来より樹脂に抗菌剤等を混合することが行われている。
【０００３】
【発明が解決しようとする課題】
抗菌剤として、ＺｎＯを主成分とするガラスが提案されている。例えば特開平７−２５７９３８号のＺｎＯ−Ｂ2Ｏ3−Ｎａ2Ｏ系の組成を有する抗菌性ガラスや特開平１１−６０２６８号のＺｎＯ−Ｂ2Ｏ3−ＳｉＯ2系の抗菌性ガラスが開示されている。
【０００４】
しかしながら、上記したようなＺｎＯ含有ガラスにおける抗菌性能では十分な抗かび性能を得ることができないのが現状である。
【０００５】
本発明の目的は、抗かび性能を向上させたＺｎＯ含有ガラスとこれを含む樹脂組成物を提供することである。
【０００６】
【課題を解決するための手段】
本発明者は種々の実験を行った結果、ＺｎＯ系ガラスにＡｇ2Ｏを適当量添加したガラス組成を用いれば、上記目的が達成できることを見出し、本発明として提案するものである。
【０００７】
即ち、本発明の抗かび性ガラスは、質量％でＺｎＯ ４０〜７０％、Ａｇ２Ｏ ３．０１〜２０％、Ｂ２Ｏ３＋ＳｉＯ２＋Ｐ２Ｏ５ ２０〜４３．０％、Ｂ２Ｏ３ １〜３０％、Ｒ２Ｏ（Ｒ：Ｎａ、Ｌｉ、Ｋ）０〜５％、Ｒ′Ｏ（Ｒ′：Ｍｇ、Ｃａ、Ｓｒ、Ｂａ）０〜３０％、Ａｌ２Ｏ３ ０〜２０％からなることを特徴とする。
【０００８】
また、本発明の樹脂組成物は、抗かび性ガラスが含有されてなる樹脂組成物において、該抗かび性ガラスの組成が質量％でＺｎＯ ４０〜７０％、Ａｇ２Ｏ ３．０１〜２０％、Ｂ２Ｏ３＋ＳｉＯ２＋Ｐ２Ｏ５ ２０〜４３．０％、Ｂ２Ｏ３ １〜３０％、Ｒ２Ｏ（Ｒ：Ｎａ、Ｌｉ、Ｋ）０〜５％、Ｒ′Ｏ（Ｒ′：Ｍｇ、Ｃａ、Ｓｒ、Ｂａ）０〜３０％、Ａｌ２Ｏ３ ０〜２０％からなることを特徴とする。
【０００９】
【発明の実施の形態】
抗菌性とは、バクテリア等の細菌の増殖を抑える働きであり、抗かび性とは、かびの繁殖を抑える働きである。
【００１０】
本発明の抗かび性ガラスは、ＺｎＯの抗菌性能とＡｇ2Ｏの抗菌及び抗かび性能を併せ持っている。
【００１１】
次に、上記の組成範囲に限定した理由を下記に示す。
【００１２】
ＺｎＯは抗菌性を与える主要因子であり、かびの栄養分となる細菌の繁殖を抑制し、抗かび性能の発現に寄与する成分である。ＺｎＯの含有量は４０〜７０質量％で、好ましくは４０〜６５質量％である。ＺｎＯが４０質量％より少なくなるとガラスの抗菌性能が低下し、７０質量％を超えるとガラス化が困難になる。
【００１３】
Ａｇ2Ｏは細菌の繁殖を抑制する抗菌性能に加え、かび自体の繁殖を直接抑制する抗かび性能を付与する成分である。Ａｇ２Ｏの含有量は３．０１〜２０質量％で、好ましくは３．０１〜１０質量％である。Ａｇ２Ｏが３．０質量％以下になるとガラスの抗かび力の付与効果としては不足する。一方、Ａｇ２Ｏが２０質量％を超えるとガラス内に安定に担持できないため、樹脂等に変色を起こし、コスト的にも不利になる。
【００１４】
Ｂ２Ｏ３＋ＳｉＯ２＋Ｐ２Ｏ５はガラス形成成分であり、同時にＡｇ２Ｏをガラス内に安定に担持するための成分である。Ｂ２Ｏ３＋ＳｉＯ２＋Ｐ２Ｏ５の含有量は２０〜４３．０質量％である。Ｂ２Ｏ３＋ＳｉＯ２＋Ｐ２Ｏ５が２０質量％より少なくなると、Ａｇ２Ｏを安定に担持し難くなり、またガラス化が困難になる。一方、Ｂ２Ｏ３＋ＳｉＯ２＋Ｐ２Ｏ５が４３．０質量％を超えるとガラスの耐水性が高くなりすぎて、ＺｎやＡｇイオンが溶出しにくくなり、ひいては抗菌及び抗かび性能の低下につながる。また、各成分の含有量は、Ｂ２Ｏ３が１〜３０質量％であり、ＳｉＯ２が０〜１６質量％で、好ましくは０〜１５質量％であり、Ｐ２Ｏ５が０．１〜４０質量％で、好ましくは０．５〜４０質量％である。更に、Ａｇ２Ｏを安定に担持させるためには、Ｂ２Ｏ３＋Ｐ２Ｏ５≧２０質量％であることが好ましい。
【００１５】
Ｒ2Ｏ（Ｒ：Ｎａ、Ｌｉ、Ｋ）はガラスの溶融性を改善する目的で５質量％まで添加してもよい。しかし、上記したように変色等の樹脂の外観に影響を及ぼすため、できれば２質量％以下にするのが好ましい。
【００１６】
Ｒ′Ｏ（Ｒ′：Ｍｇ、Ｃａ、Ｓｒ、Ｂａ）については、ガラスの粘性を下げる効果があり、ガラスの溶融を助けるフラックスのような働きをする。Ｒ’Ｏの含有量は３０質量％まで、好ましくは２０質量％まで添加することができる。
【００１７】
Ａｌ2Ｏ3についても同様にガラス化を助ける働きがあり、２０質量％まで、好ましくは１５質量％まで添加することができる。
【００１８】
本発明の抗かび性ガラスは、例えば粉末状、繊維状、フレーク状等種々の形態で提供することができる。中でもガラス粉末の形態で提供すると比表面積が大きくなるため、高い抗かび性能が得られる。ガラス粉末の場合、平均粒径が０．５〜２０μｍ、特に１．０〜１０μｍであることが好ましい。つまりガラス粉末の平均粒径が０．５μｍより小さいと凝集効果により、樹脂等に混練し難くなり、２０μｍより大きくなると単位重量当りのＺｎ2+イオン、Ａｇ+イオンの溶出量が小さくなり好ましくないためである。
【００１９】
本発明の抗かび性ガラスは、熱可塑性樹脂や熱硬化性樹脂の充填用抗かび剤として使用可能である。例えば、ポリオレフィン系樹脂、ＡＢＳ樹脂、ＡＳ樹脂、ポリウレタン系樹脂、ポリビニルアルコール樹脂、ポリエステル樹脂、ポリエチレンオキシド系樹脂、ポリフェニルサルファイド系樹脂、アクリル樹脂、メラミン樹脂、フェノール系樹脂、エポキシ系樹脂、ユリア系樹脂、ポリイミド系樹脂、脂肪族系ナイロン樹脂、ポリ塩化ビニル系樹脂、ポリ塩化ビニデン樹脂、酢酸ビニル系樹脂、フッ素系樹脂又はシリコーン系樹脂、主要なエンジニアリングプラスティック（ポリカーボネート樹脂、ポリアミド系樹脂等）等やこれらの複合体、若しくはガラス繊維、ボロン繊維、炭素繊維等で強化された樹脂にも使用可能である。
【００２０】
なお、本発明の抗かび性ガラスは樹脂充填用に限られるものではなく、例えばガラスやセラミックの抗かび性釉薬、金属の抗かび性塗料等、種々の抗菌及び抗かび用途に使用可能である。
【００２１】
本発明の樹脂組成物は、上記した抗かび性ガラスを含有するものであり、その含有量は０．０１〜７０質量％、特に０．０５〜３０質量％であることが望ましい。含有量をこのように限定した理由は、０．０１質量％より少ないと樹脂に十分な抗かび性を付与しにくくなる。一方、ガラスの含有量が７０質量％を超えると、樹脂内での分散が困難になり、マスターバッチ成形の限界である。また、抗かび性能の効果もほとんど変わらないため、コスト的にもあまり有効ではないからである。
【００２２】
なお本発明の樹脂組成物においては、抗かび性ガラス以外にも、通常樹脂に含有される各種の添加物を含有させることが可能である。
【００２３】
【実施例】
以下、本発明を実施例に基づいて説明する。
【００２４】
【表１】
表１は、本発明の実施例（試料Ｎｏ．１〜７）と比較例（試料Ｎｏ．８、９）を示している。
【００２６】
各試料は次のようにして作製した。
【００２７】
まず、上記の原料を所定の混合量になるように十分に混合した後、白金−ロジウム合金坩堝に入れ、１２００〜１５５０℃で４時間溶融した。ところで、銀原料として、酸化銀、燐酸銀、硝酸銀、或いは銀が添加されているガラスが使用できる。ここで溶融中での銀イオンの還元を防ぐ目的で、酸化セリウム等の酸化性の物質を少量添加して溶融しても良い。溶融後、肉厚が約１ｍｍのフィルム状カレットに成形した。これをボールミルによって粉砕し、目開き５０ミクロンの篩を通し、ガラス粉末の平均粒径が空気透過式比表面積測定装置＜（株）島津製作所製＞で約５μｍになるように調整し、試料を得た。ボールミル粉砕に用いる助剤は、水、アルコール、過酸化水素水等を使用することができる。
【００２８】
抗かび性については、抗菌技術製品協議会の定める試験法「抗菌剤の抗菌力評価試験法最小発育阻止濃度測定法Ｉ（１９９８年度改訂版）液体培地希釈法によるＭＩＣ測定法」に則り、ＭＩＣ値として抗かび性を評価した。（試験菌：黒麹かび）
表１から明らかなように、すべての実施例でＭＩＣ値が４００（μｇ／ｍｌ）以下であった。抗菌技術製品協議会の示す抗菌剤としての基準値の８００（μｇ／ｍｌ）以下を十分にクリアーしていることから、良好な抗かび性を示すことがわかる。比較例のＡｇ2Ｏ含有量の少ないＮｏ．８のＭＩＣ値は１６００（μｇ／ｍｌ）で、抗かび性が劣っていた。Ａｇ2Ｏ含有量が多いＮｏ．９のＭＩＣ値は１００（μｇ／ｍｌ）と抗かび性能は優れているが、ガラスは変色していた。
【００２９】
【表２】
次に、さらに抗かび性能を調査するために、実施例Ｎｏ．１、２及び比較例Ｎｏ．８，９の抗かび性ガラスとポリプロピレン樹脂を、抗かび性ガラスの含有量が１．０％になるように混合し、約５０×５０×２ｍｍの板状に成形し、その抗かび性及び樹脂の外観観察について評価した。それらの結果を表２に示す。
【００３１】
抗かび性試験方法は、ＪＩＳＺ２９１１のかび抵抗性試験方法に準拠して行った。（試験かび：黒麹かび）
【００３２】
【表３】
抗かび性の評価は、表３に示した評価基準によって行い、外観については、目視でブランクとの比較評価で行った。
【００３４】
表２よりＮｏ．１及びＮｏ．２のガラスについては、良好な抗かび性を示した。一方、Ａｇ2Ｏ含有量の少ない比較例Ｎｏ．８については、抗かび性が劣っていた。また、比較例Ｎｏ．９については、良好な抗かび性を示すが、銀を過剰に含んでいるため、樹脂との混合時に反応して外観不良が生じた。
【００３５】
【発明の効果】
以上説明したように、本発明の抗かび性ガラスはガラスとして安定しており、また樹脂に充填しても十分な抗かび性を付与することができる。しかも樹脂製品の外観に影響を及ぼさないので、樹脂充填用抗かび剤として好ましい。
【００３６】
それゆえ、清潔さが要求される歯ブラシ、石鹸入れ、たらい、洗面台、浴槽等の樹脂製品等の用途に好適に使用できる。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an antifungal glass and a resin composition containing the same.
[0002]
[Prior art]
Resin products such as toothbrushes, soap bowls, tubs, washstands, and bathtubs are used under high-humidity conditions for a long time, so that bacteria and fungi are prone to multiply. In order to suppress the growth of bacteria and fungi, an antibacterial agent or the like has been conventionally mixed with a resin.
[0003]
[Problems to be solved by the invention]
As an antibacterial agent, glass mainly composed of ZnO has been proposed. For example, an antibacterial glass having a ZnO-B 2 O 3 —Na 2 O-based composition disclosed in JP-A-7-257938 and a ZnO—B 2 O 3 —SiO 2- based antibacterial glass disclosed in JP-A-11-60268 are disclosed. Has been.
[0004]
However, at present, sufficient antifungal performance cannot be obtained with the antibacterial performance of the ZnO-containing glass as described above.
[0005]
An object of the present invention is to provide a ZnO-containing glass with improved antifungal performance and a resin composition containing the same.
[0006]
[Means for Solving the Problems]
As a result of various experiments, the present inventor has found that the above object can be achieved by using a glass composition obtained by adding an appropriate amount of Ag 2 O to ZnO-based glass, and proposes the present invention.
[0007]
That is, the antifungal glass of the present invention is ZnO 40 to 70% by mass, Ag 2 O 3.01 to 20%, B 2 O 3 + SiO 2 + P 2 O 5 20 to 43.0 %, B 2 O. 3 1~30%, R 2 O ( R: Na, Li, K) 0~5%, R'O (R ': Mg, Ca, Sr, Ba) 0~30%, Al 2 O 3 0~20 %.
[0008]
Moreover, the resin composition of the present invention is a resin composition containing antifungal glass, wherein the composition of the antifungal glass is ZnO 40 to 70% and Ag 2 O 3.01 to 20% by mass%. , B 2 O 3 + SiO 2 + P 2 O 5 20 to 43.0 %, B 2 O 3 1 to 30%, R 2 O (R: Na, Li, K) 0 to 5%, R′O (R ′ : Mg, Ca, Sr, Ba) 0 to 30%, Al 2 O 3 0 to 20%.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Antibacterial is a function of suppressing the growth of bacteria such as bacteria, and antifungal is a function of suppressing the growth of mold.
[0010]
The antifungal glass of the present invention has both the antibacterial performance of ZnO and the antibacterial and antifungal performance of Ag 2 O.
[0011]
Next, the reason for limiting to the above composition range is shown below.
[0012]
ZnO is a main factor that imparts antibacterial properties, and is a component that contributes to the development of antifungal performance by suppressing the growth of bacteria, which are nutrients for fungi. The content of ZnO is 40 to 70% by mass, preferably 40 to 65% by mass. When ZnO is less than 40% by mass, the antibacterial performance of the glass is lowered, and when it exceeds 70% by mass, vitrification becomes difficult.
[0013]
Ag 2 O is an ingredient that imparts antifungal performance that directly inhibits the growth of mold itself, in addition to the antibacterial performance of inhibiting the growth of bacteria. The content of Ag 2 O is 3.01 to 20 % by mass, preferably 3.01 to 10% by mass. When Ag 2 O is 3.0% by mass or less, the effect of imparting antifungal force to the glass is insufficient. On the other hand, if Ag 2 O exceeds 20% by mass, the resin cannot be stably supported in the glass, causing discoloration of the resin and the like, which is disadvantageous in terms of cost.
[0014]
B 2 O 3 + SiO 2 + P 2 O 5 is a glass forming component, and at the same time, a component for stably supporting Ag 2 O in the glass. The content of B 2 O 3 + SiO 2 + P 2 O 5 is Ru 20 to 43.0% by mass. When B 2 O 3 + SiO 2 + P 2 O 5 is less than 20% by mass, it becomes difficult to stably support Ag 2 O and vitrification becomes difficult. On the other hand, if B 2 O 3 + SiO 2 + P 2 O 5 exceeds 43.0 % by mass, the water resistance of the glass becomes too high and Zn and Ag ions are difficult to elute, resulting in a decrease in antibacterial and antifungal performance. Connected. The content of each component, B is a 2 O 3 is 1 to 30 wt%, of SiO 2 is 0 to 16 wt%, preferably from 0 to 15% by weight, P 2 O 5 0.1 It is -40 mass%, Preferably it is 0.5-40 mass%. Furthermore, in order to stably carry Ag 2 O, it is preferable that B 2 O 3 + P 2 O 5 ≧ 20% by mass.
[0015]
R 2 O (R: Na, Li, K) may be added up to 5% by mass for the purpose of improving the meltability of the glass. However, since it affects the appearance of the resin such as discoloration as described above, it is preferable to make it 2% by mass or less if possible.
[0016]
R′O (R ′: Mg, Ca, Sr, Ba) has an effect of lowering the viscosity of the glass and acts as a flux that helps the glass melt. The content of R′O can be added up to 30% by mass, preferably up to 20% by mass.
[0017]
Al 2 O 3 also has the function of assisting vitrification, and can be added up to 20% by mass, preferably up to 15% by mass.
[0018]
The antifungal glass of the present invention can be provided in various forms such as powder, fiber and flakes. Above all, when it is provided in the form of glass powder, the specific surface area is increased, so that high antifungal performance is obtained. In the case of glass powder, the average particle size is preferably 0.5 to 20 μm, particularly 1.0 to 10 μm. In other words, if the average particle size of the glass powder is smaller than 0.5 μm, it becomes difficult to knead into a resin or the like due to the agglomeration effect, and if it exceeds 20 μm, the elution amount of Zn 2+ ions and Ag + ions per unit weight is unfavorable. Because.
[0019]
The antifungal glass of the present invention can be used as an antifungal agent for filling a thermoplastic resin or a thermosetting resin. For example, polyolefin resin, ABS resin, AS resin, polyurethane resin, polyvinyl alcohol resin, polyester resin, polyethylene oxide resin, polyphenyl sulfide resin, acrylic resin, melamine resin, phenol resin, epoxy resin, urea resin Resin, polyimide resin, aliphatic nylon resin, polyvinyl chloride resin, polyvinylidene chloride resin, vinyl acetate resin, fluorine resin or silicone resin, main engineering plastic (polycarbonate resin, polyamide resin, etc.), etc. Or a composite thereof, or a resin reinforced with glass fiber, boron fiber, carbon fiber, or the like.
[0020]
The antifungal glass of the present invention is not limited to resin filling, and can be used for various antibacterial and antifungal applications such as glass and ceramic antifungal glazes and metal antifungal paints. .
[0021]
The resin composition of the present invention contains the above-mentioned antifungal glass, and the content thereof is preferably 0.01 to 70% by mass, particularly 0.05 to 30% by mass. The reason for limiting the content in this way is that if it is less than 0.01% by mass, it becomes difficult to impart sufficient antifungal properties to the resin. On the other hand, if the glass content exceeds 70% by mass, dispersion in the resin becomes difficult, which is the limit of master batch molding. Moreover, since the effect of the antifungal performance is hardly changed, it is not very effective in terms of cost.
[0022]
In addition, in the resin composition of this invention, it is possible to contain the various additives normally contained in resin other than antifungal glass.
[0023]
【Example】
Hereinafter, the present invention will be described based on examples.
[0024]
[Table 1]
Table 1 shows Examples (Sample Nos. 1 to 7) and Comparative Examples (Sample Nos. 8 and 9) of the present invention.
[0026]
Each sample was produced as follows.
[0027]
First, after sufficiently mixing the above raw materials so as to have a predetermined mixing amount, it was put in a platinum-rhodium alloy crucible and melted at 1200 to 1550 ° C. for 4 hours. By the way, silver oxide, silver phosphate, silver nitrate, or glass to which silver is added can be used as a silver raw material. Here, for the purpose of preventing reduction of silver ions during melting, a small amount of an oxidizing substance such as cerium oxide may be added and melted. After melting, it was formed into a film cullet having a thickness of about 1 mm. This was pulverized by a ball mill, passed through a sieve with an opening of 50 microns, and the average particle size of the glass powder was adjusted to about 5 μm with an air permeation specific surface area measuring device <manufactured by Shimadzu Corporation>. Obtained. As the auxiliary agent used for ball milling, water, alcohol, hydrogen peroxide water or the like can be used.
[0028]
The antifungal property is determined by the MIC in accordance with the test method “Minimum Growth Inhibitory Concentration Measurement Method I (1998 Revised Edition) MIC Measurement Method by Liquid Medium Dilution Method” established by the Antimicrobial Technology Products Council. The antifungal property was evaluated as a value. (Test fungus: black mold)
As is apparent from Table 1, the MIC value was 400 (μg / ml) or less in all Examples. Since the standard value of 800 (μg / ml) or less as an antibacterial agent shown by the Antibacterial Technology Products Council is sufficiently cleared, it can be seen that the antifungal property is exhibited. Comparative Example No. 2 with a low Ag 2 O content. The MIC value of 8 was 1600 (μg / ml), and the antifungal property was inferior. No. 2 with high Ag 2 O content. The MIC value of 9 was 100 (μg / ml) and the antifungal performance was excellent, but the glass was discolored.
[0029]
[Table 2]
Next, in order to further investigate the antifungal performance, Example No. 1 and 2 and Comparative Example No. The antifungal glass of 8 and 9 and the polypropylene resin were mixed so that the content of the antifungal glass was 1.0%, and formed into a plate shape of about 50 × 50 × 2 mm. The appearance observation of the resin was evaluated. The results are shown in Table 2.
[0031]
The antifungal test method was performed in accordance with the fungus resistance test method of JISZ2911. (Test mold: black mold)
[0032]
[Table 3]
The antifungal property was evaluated according to the evaluation criteria shown in Table 3, and the appearance was visually evaluated by comparison with a blank.
[0034]
From Table 2, No. 1 and no. The glass No. 2 showed good antifungal properties. On the other hand, little comparative example of Ag 2 O content No. About 8, the antifungal property was inferior. Comparative Example No. No. 9 showed good antifungal properties, but contained an excessive amount of silver, and thus reacted when mixed with the resin, resulting in poor appearance.
[0035]
【Effect of the invention】
As described above, the antifungal glass of the present invention is stable as a glass, and can provide sufficient antifungal properties even when filled in a resin. And since it does not affect the external appearance of a resin product, it is preferable as an antifungal agent for resin filling.
[0036]
Therefore, it can be suitably used for applications such as toothbrushes, soap holders, tubs, washstands, and bathtubs that require cleanliness.
