Description

【０００１】
【産業上の利用分野】
本発明は、銀、亜鉛など抗菌性を有する金属イオンを１種又は２種含有する抗菌性ガラス繊維に関するものである。さらに、ＦＲＰ等のプラスチックにフィラーとして練り込み、増強と抗菌の役目をもつものである。
【０００２】
【従来の技術】
従来、ガラス繊維に抗菌性を付与する場合は、ガラス繊維を作製後に、スプレー、ディッピングなどの後加工により行われていた。しかし、この後加工による抗菌付与方法は、手間がかかるとともに専用の機械が必要となり、これによりコスト高などの欠点を有することとなっていた。また、後加工であるため、はがれ等により抗菌性がなくなる可能性が高く、その改善が求められていた。
【０００３】
【発明が解決しようとする課題】
本発明は、上記した従来欠点を解消してガラス繊維の組成に抗菌性を有する金属イオンを含有させて作製することにより、後加工する手間がなく専用の機械も必要としない抗菌性ガラス繊維を提供することにある。また、はがれ等がないため十分に抗菌性が発揮されるため、耐久性が向上する。
【０００４】
【課題を解決するための手段】
上記の課題を解決するためになされた本発明の抗菌性ガラス繊維は、銀、亜鉛の金属イオンのうち少なくとも１種以上を含有する抗菌性ガラス繊維であって、銀を０．５〜５重量％の範囲で含有するかもしくは亜鉛を１０〜３０重量％の範囲で含有し、ベースの組成がＳｉＯ2：５０〜６０重量％、Ａｌ2Ｏ3：１０〜２０重量％、ＣａＯ：１０〜３０重量％、ＭｇＯ：０〜１０重量％、Ｂ2Ｏ3：５〜１５重量％からなることを特徴とするものである。
【０００５】
【発明実施の形態】
ここで、銀イオンの含有量が規定されているのは、０．５重量％以下では、十分な抗菌効果がなく、逆に５重量％以上では必要ないからである。亜鉛も同様に１０重量％以下では、十分な抗菌効果がなく、逆に３０重量％以上では必要ないからである。さらに、ベース組成のうちＳｉＯ2は５０〜６０重量％の範囲である必要があるが、５０重量％以下ではガラスの粘性が低くなり繊維にしにくく、また、６０重量％以上であると逆に粘性が高くなりすぎるために繊維には向かない。Ａｌ2Ｏ3も同様に１０重量％以下ではガラスの粘性が低くなり繊維にしにくく、２０重量％以上であると逆に粘性が高くなりすぎるために繊維には向かない。ＣａＯも同様に１０重量％以下ではガラスの粘性が低くなり繊維にしにくく、３０重量％以上であると逆に粘性が高くなりすぎるために繊維には向かない。ＭｇＯは必ずしも含まなくてもよいが、１０重量％以上であると粘性が高くなりすぎるために繊維には向かない。
【０００６】
（実施例１）
表１に示す組成により原料を調合し、１６００℃で溶融し、火焔延伸法により短繊維を作製した。この時の直径は１０μｍであった。さらに、それぞれ抗菌効果をシェイクフラスコ法により、菌液７５ｍｌに対してサンプル０．７５ｇを取り２４時間培養後の菌数を計数した。なお、開始時の菌数は、３．０×１０4 個であった。その結果を表２に示す。

【発明の効果】
以上説明したように、本発明の抗菌性ガラス繊維は、後加工する必要もなく、繊維作製と同時に抗菌性を付与できる。また後加工でないため、特に専用機械も必要なく、抗菌剤などの欠落もないため抗菌寿命が長い。さらに、ＦＲＰ等のプラスチックにフィラーとして練り込むことによって、増強と抗菌の両方の役目をもたせることもできる。
よって本発明は従来の問題点を一掃した抗菌性ガラス繊維として極めて大きい意義がある。[0001]
[Industrial application fields]
The present invention relates to an antibacterial glass fiber containing one or two metal ions having antibacterial properties such as silver and zinc . Furthermore, it is kneaded as a filler in plastics such as FRP, and has the role of strengthening and antibacterial.
[0002]
[Prior art]
Conventionally, when an antibacterial property is imparted to a glass fiber, it has been performed by post-processing such as spraying and dipping after the glass fiber is produced. However, this antibacterial application method by post-processing is troublesome and requires a dedicated machine, which has disadvantages such as high cost. Moreover, since it is post-processing, there is a high possibility that the antibacterial property will be lost due to peeling or the like, and there has been a demand for its improvement.
[0003]
[Problems to be solved by the invention]
The present invention eliminates the above-mentioned conventional drawbacks and makes the composition of glass fiber contain metal ions having antibacterial properties, so that antibacterial glass fibers that do not require post-processing and do not require a dedicated machine can be obtained. It is to provide. In addition, since there is no peeling or the like, the antibacterial property is sufficiently exhibited, and thus durability is improved.
[0004]
[Means for Solving the Problems]
The antibacterial glass fiber of the present invention made to solve the above problems is an antibacterial glass fiber containing at least one of silver and zinc metal ions, and contains 0.5 to 5 weight of silver. % of whether or zinc containing a range contained in the range of 10 to 30 wt%, based composition SiO 2: 50-60 wt%, Al 2 O 3: 10~20 wt%, CaO: 10 to 30 wt%, MgO: 0 wt%, B 2 O 3: and is characterized in that consisting of 5 to 15 wt%.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Here, the reason why the content of silver ions is defined is that when the amount is 0.5% by weight or less, there is no sufficient antibacterial effect, and conversely, 5% by weight or more is not necessary. Similarly, if zinc is 10% by weight or less, there is no sufficient antibacterial effect, and conversely, if it is 30% by weight or more, it is not necessary. Furthermore, in the base composition, SiO 2 needs to be in the range of 50 to 60% by weight. However, if it is 50% by weight or less, the viscosity of the glass is lowered and it is difficult to form a fiber. Is too high to be suitable for fibers. Similarly, Al 2 O 3 is less than 10% by weight because the viscosity of the glass is low and difficult to be formed into a fiber, whereas when it is 20% by weight or more, the viscosity is too high and is not suitable for fiber. Similarly, if CaO is 10% by weight or less, the viscosity of the glass is low and the fiber is difficult to be formed. MgO may not necessarily be contained, but if it is 10% by weight or more, the viscosity becomes too high, so it is not suitable for fibers.
[0006]
(Example 1)
Raw materials were prepared according to the composition shown in Table 1, melted at 1600 ° C., and short fibers were prepared by flame drawing. The diameter at this time was 10 μm. Furthermore, the antibacterial effect was measured by shake flask method, and 0.75 g of sample was taken for 75 ml of the bacterial solution, and the number of bacteria after 24 hours of culture was counted. The number of bacteria at the start was 3.0 × 10 4 . The results are shown in Table 2.

【The invention's effect】
As described above, the antibacterial glass fiber of the present invention does not need to be post-processed, and can impart antibacterial properties simultaneously with fiber production. In addition, since there is no post-processing, there is no need for a special machine, and there is no missing antibacterial agent, resulting in a long antibacterial life. Furthermore, it is possible to provide both enhancement and antibacterial functions by kneading as a filler in plastics such as FRP.
Therefore, the present invention is extremely significant as an antibacterial glass fiber that has eliminated the conventional problems.
