Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は繊維補強無気質製品の製造方法に関する。[Detailed description of the invention] [Industrial application field] FIELD OF THE INVENTION This invention relates to a method for manufacturing fiber-reinforced airless products.
繊維補強セメント製品の補強繊維としての石綿は、資源
枯渇により入手が困難となりつつ存る上、公害の原因と
もなるため、その使用が著るしく制限され、石綿の代替
物として、ガラス繊維、金属繊維、あるいは、合成樹脂
繊維など種々の繊維の適用が考えられている。Asbestos, which is used as a reinforcing fiber for fiber-reinforced cement products, is becoming difficult to obtain due to resource depletion and also causes pollution, so its use is severely restricted. Application of various fibers such as fibers or synthetic resin fibers is being considered.
しかし、上述のような石綿以外の繊維は、表面が平滑な
ため、セメントマトリックスに対する接着性が悪く、い
わゆる繊維のすり抜けが生じやすくなる問題が有った。However, since the above-mentioned fibers other than asbestos have smooth surfaces, they have poor adhesion to the cement matrix, and there is a problem in that the so-called fibers tend to slip through.
この問題は特にセメント混合物より成形品を製造後、ロ
ールにより押圧整形する場合に顕著に現われ、繊維がす
り抜けやすい結果、マトリックスの加圧による伸びが充
分に防止出来ず、繊維とセメントマトリックスとの界面
に微小なりラックを生じさせこれが製品強度を低下させ
る原因となっていた。This problem is especially noticeable when a molded product is manufactured from a cement mixture and then pressed into shape using rolls.As a result, the fibers tend to slip through and the elongation of the matrix due to pressure cannot be sufficiently prevented, causing the interface between the fibers and the cement matrix to This causes a slight rack to occur, which reduces the strength of the product.
この発明は上記問題に鑑み石綿以外の繊維であっても、
繊維のすり抜けを有効に防止出来、しかも実施も容易な
繊維補強無気質製品の製造方法を得ることを目的として
なされたものである。In view of the above-mentioned problems, this invention has been developed to
The purpose of this invention is to provide a method for manufacturing a fiber-reinforced aporous product that can effectively prevent fibers from slipping through and is easy to implement.
即ち、この発明の繊維補強無気質製品の製造方法は石綿
以外の補強用繊維を粘土と水と共に撹拌混合し、繊維表
面に粘土鉱物を付着させ、該繊維をセメント、骨材が成
る混合物に必要量添加して均一混合し、しかる後膣混合
物より成形品を製造することを特徴とするものである。That is, the method for manufacturing a fiber-reinforced airless product of the present invention involves stirring and mixing reinforcing fibers other than asbestos with clay and water, adhering clay minerals to the surface of the fibers, and adding the fibers to the mixture of cement and aggregate. The method is characterized in that a certain amount is added and mixed uniformly, and then a molded article is manufactured from the vaginal mixture.
この発明において粘土としてはカオリン、ベントナイト
などが好適に使用されるが粘土鉱物であれば特に限定さ
れない。In this invention, kaolin, bentonite, etc. are preferably used as the clay, but there is no particular limitation as long as it is a clay mineral.
これら粘土は適当な水分添加のもとに繊維と均一混合す
ると、例えガラス繊維のような表面が平滑な繊維であっ
ても粘着し、乾燥しても容易に剥離することはない。When these clays are uniformly mixed with fibers under the addition of appropriate moisture, they stick even to fibers with smooth surfaces such as glass fibers, and do not easily peel off even when dried.
かかる粘土の性質を利用し、繊維に粘土鉱物を付着させ
、セメントマトリックスとの接着性向上に寄与させるの
である。Utilizing the properties of clay, clay minerals are attached to the fibers, contributing to improved adhesion with the cement matrix.
上記繊維と粘土との混合は繊維１０．１重量％〜５重量
％に対し、粘土５重世％〜３０重量％、残部を水とした
混合割合とされる。The above-mentioned fibers and clay are mixed at a mixing ratio of 10.1% to 5% by weight of fibers, 5% to 30% by weight of clay, and the balance being water.
また、繊維としては石綿以外のすべての繊が適用可能で
あり、代表的なものとし”で、ビニロン、ナイロン等の
合成繊維、ガラズ、金属等の無機質繊維、パルプなどの
有機繊維が使用される。In addition, all fibers other than asbestos can be used as fibers, and typical examples include synthetic fibers such as vinylon and nylon, inorganic fibers such as glass and metal, and organic fibers such as pulp. .
次に、この発明の詳細な説明する。 Next, the present invention will be explained in detail.
〈実施例１〉
繊維として、パルプ繊維を５重量％、粘土（ベントナイ

結果が得られた。When this reinforcing pulp fiber was formed into a plate according to the axial dimensions using the formulation shown in Table 1, and this was rolled and shaped using rolls, the elongation rate was 4.3%. The growth rate was lower than that of 5.7%. The elongation rate shown here is (length of the sample after rolling) - (length of the sample before rolling) Next, the above plate-shaped body was naturally cured for 2 days, and then autoclaved at 3.5 atmC for 10 hours. After curing and strength testing, the results shown in the lower column of Table 1 were obtained.

When a plate material was formed in the same manner as in Example 1 and rolled and shaped, the elongation rate of the uncured plate material was 4.8%, and in the case of glass fiber without clay attached, it was 6.5%. The growth rate was lower than that of

された。Next, when the above-mentioned plate-like body was cured and hardened in the same manner as in Example 1, the bending strength was 195.0 kg/1ffl, which was 170.5 kg/cd when no clay treatment was performed. It was confirmed that there was an improvement. [Example 3] Using vinylon fiber instead of the valve fiber in Example 1, the original plate was rolled and shaped and cured in the same manner as in Example 1. The elongation rate at the time of rolling and shaping was 4.4%, and clay adhesion was observed. Compared to the case without treatment, which was 6.0%, it was lower by 1! The bending strength of the molded plate is 194.5.
kir/-, and the case without clay adhesion treatment is 168
．． It was confirmed that the strength was increased compared to 0 kg/-.
また、半乾式法、湿式法により同様に板状体を成形した
ところ、いずれも粘土付着処理を行った場合強度向上す
ることが確認された。In addition, when plate-shaped bodies were similarly formed using a semi-dry method and a wet method, it was confirmed that the strength was improved when clay adhesion treatment was performed in both cases.
この発明は以上説明したように、繊維外周に付着させた
粘土鉱物粒子によりセメントマトリックスとの引掛性が
改善され、未硬化時を含めて板材の曲げ強度が著しく改
良されるのである。As explained above, in this invention, the clay mineral particles attached to the outer periphery of the fibers improve the hookability with the cement matrix, and the bending strength of the plate material, even when uncured, is significantly improved.
また、原料配合時に必要な繊維を粘土と混合すれば良い
だけであるから、実施も容易であるなどの効果を有する
。Furthermore, since it is only necessary to mix the necessary fibers with the clay when blending the raw materials, it has the advantage of being easy to implement.
