Description
本発明は、生体溶解性に優れる無機繊維に関する。 The present invention relates to an inorganic fiber excellent in biosolubility.
アスベストは、軽量で扱いやすく且つ耐熱性に優れるため、例えば、耐熱性のシール材として使用されていた。しかしアスベストは人体に吸入されて肺に疾患を引き起こすため使用が禁止され、これに代わりにセラミック繊維等が使用されている。セラミック繊維等は、耐熱性がアスベストに匹敵する程高く、適切な取り扱いをすれば健康上の問題は無いと考えられているが、より安全性を求められる風潮がある。そこで、人体に吸入されても問題を起こさない又は起こしにくい生体溶解性無機繊維を目指して、様々な生体溶解性繊維が開発されている（例えば、特許文献１，２，３）。 Asbestos has been used, for example, as a heat-resistant sealing material because it is lightweight, easy to handle, and excellent in heat resistance. However, since asbestos is inhaled by the human body and causes diseases in the lungs, its use is prohibited, and ceramic fibers and the like are used instead. Although ceramic fibers and the like have heat resistance as high as that of asbestos and are considered to have no health problems if properly handled, there is a trend that safety is required more. Then, various biosoluble fibers are developed aiming at a biosoluble inorganic fiber which does not cause or hardly cause a problem even when it is inhaled by the human body (for example, Patent Documents 1, 2, and 3).
従来の無機繊維は、アスベストと同様に、様々なバインダーや添加物とともに、定形物、不定形物に二次加工されて、熱処理装置、工業窯炉や焼却炉等の炉における目地材、耐火タイル、断熱レンガ、鉄皮、モルタル耐火物等の隙間を埋める目地材、シール材、パッキング材、断熱材等として用いられている。炉内の部材にアルミナが使用されていることが多く、二次加工品に含まれる繊維が、このアルミナと反応し二次加工品や部材が付着したり溶融したりする問題があった。 Similar to asbestos, conventional inorganic fibers are secondary processed into fixed and irregular products with various binders and additives, and heat treatment equipment, joints in furnaces such as industrial kilns and incinerators, refractory tiles, etc. They are used as joint materials, sealing materials, packing materials, heat insulating materials, etc. for filling gaps such as heat insulating bricks, iron skins, mortar refractories, etc. Alumina is often used for the members in the furnace, and there is a problem that the fibers contained in the secondary processed product react with the alumina to cause adhesion or melting of the secondary processed product or members.
本発明の目的は、生体溶解性に優れる新規な無機繊維を提供することである。 An object of the present invention is to provide a novel inorganic fiber which is excellent in biosolubility.

無機繊維は溶融法、ゾルゲル法等公知の方法で製造できるが、低コストのため溶融法が好ましい。溶融法では、通常の方法により、原料の溶融物を作製し、この溶融物を繊維化して製造する。例えば、高速回転しているホイール上に熔解した原料を流し当てることで繊維化するスピニング法及び熔解した原料に圧縮空気を当てることで繊維化するブロー法等により製造できる。 The inorganic fiber can be produced by a known method such as a melting method or a sol-gel method, but the melting method is preferred because of low cost. In the melting method, a melt of the raw material is produced by a usual method, and the melt is fiberized and manufactured. For example, it can be manufactured by a spinning method for fiberizing by pouring the melted raw material on a wheel rotating at a high speed, and a blowing method for fiberizing by applying compressed air to the melted raw material.
本発明の無機繊維の平均繊維径は、通常０．１〜５０μｍ、好ましくは０．５〜２０μｍ、さらに好ましくは１〜１０μｍ、最も好ましくは１〜８μｍである。平均繊維径は、所望の繊維径になるように回転数、加速度、圧縮空気圧力、風速、風量等、既知の製造方法で調整すればよい。 The average fiber diameter of the inorganic fiber of the present invention is usually 0.1 to 50 μm, preferably 0.5 to 20 μm, more preferably 1 to 10 μm, and most preferably 1 to 8 μm. The average fiber diameter may be adjusted by a known manufacturing method such as the number of revolutions, acceleration, compressed air pressure, wind speed, air volume, and the like so as to obtain a desired fiber diameter.
また、本発明の無機繊維は、加熱処理してもしなくてもよい。
加熱処理する場合は、繊維形状を維持する温度であればよい。加熱温度、加熱時間により繊維物性が変化するので適宜所望の性能（耐クリープ性、収縮率、強度、弾性）がでるように処理すればよい。
所定の加熱処理により無機繊維は非晶質から結晶質へ変化するが、上記の記載のように所望の性能がでればよく、非晶質、結晶質のどちらの状態でもよく、非晶質、結晶質部分がそれぞれが混在している状態でもよい。
加熱温度は、例えば１００℃以上、３００℃以上、好ましくは、６００℃以上、８００℃以上、さらに好ましくは１０００℃以上、１２００℃以上、１３００℃以上、１４００℃以上でよく、６００℃〜１４００℃、さらに好ましくは、８００℃〜１２００℃、８００℃〜１０００℃である。
In addition, the inorganic fiber of the present invention may or may not be heat-treated.
When heat-processing, what is necessary is just the temperature which maintains a fiber shape. Since the fiber physical properties change depending on the heating temperature and the heating time, it may be treated so as to give desired properties (creep resistance, shrinkage rate, strength, elasticity) appropriately.
Although the inorganic fiber is changed from amorphous to crystalline by the predetermined heat treatment, as long as the desired performance can be obtained as described above, it may be either amorphous or crystalline, and amorphous And crystalline portions may be mixed with each other.
The heating temperature may be, for example, 100 ° C. or more, 300 ° C. or more, preferably 600 ° C. or more, 800 ° C. or more, more preferably 1000 ° C. or more, 1200 ° C. or more, 1300 ° C. or more, 1400 ° C. or more, 600 ° C. to 1400 ° C. More preferably, they are 800 ° C-1200 ° C, and 800 ° C-1000 ° C.

The solubility is preferably 10 mg / g sample or more, 20 mg / g sample or more, and 30 mg / g sample or more as determined by the method described in Example 30 .
