められている。The wet spraying method, in which a kneaded paste material is sprayed onto pillars, beams, and walls of buildings, has long been used as a coating material whose main composition is cement as an adhesive and asbestos as a fiber reinforcement. Recently, as asbestos pollution has become a problem, materials are being changed to replace fiber reinforcement with other active ingredients.

湿式吹付材が提案されている（特開昭６３−２９７２５
６号公報）。The most typical asbestos substitute material is rock wool, and a wet spraying material for forming fire-resistant coatings containing a hydraulic inorganic adhesive, a surfactant, and a thickening agent has already been published in the Tokko Kokō 5
It is disclosed in Japanese Patent No. 4-29537. However, rock wool has poor entanglement properties compared to asbestos, and has the disadvantage that the interlayer strength of the formed coating layer is low. In order to overcome this drawback, a wet spraying material has been proposed in which the above components further contain fibrous hydrated magnesium silicate such as sepiolite (Japanese Patent Laid-Open No. 63-29725
Publication No. 6).

がある。In other words, the wet spray material described in JP-A No. 63-297256 uses rock wool and a hydraulic inorganic adhesive as the main materials, and adds a thickener, a surfactant, and water to this and kneads it to make it viscous. An asbestos-free wet spraying material for forming a fire-resistant coating formed into a paste, the spraying material further containing 0.5 to 10% by weight of fibrous hydrated magnesium silicate based on the total solid content. There is. However, even with this composition, there is a problem that the entanglement of the fiber components is not sufficient and the strength properties are not sufficiently improved.
本発明は前記従来技術を改良し、強度特性に優れた組成

るものである。To achieve the above object, the fireproof coating material according to the present invention is a paste material composed of Portland cement, fly ash, and rock wool as main components, and a lubricant, a thickener, an expanding agent, and water. 2-5% sepiolite and 0.1-0.4% by weight based on total solids
The structural feature is that it contains % by weight of glass fiber.

ト材料に形成したものを前提組成とする。The fire-resistant coating material of the present invention has ordinary Portland cement, fly ash as an extender, and rock wool as an aggregate as its main components, and components such as a lubricant, thickener, and swelling agent are kneaded with water. The prerequisite composition is a paste material that can be wet-sprayed.

本発明は上記成分からなるペースト材料において、全固
形分に対し２〜５重量％のセピオライトおよび０．１〜
０．４重量％のガラス繊維を含有する点に組成上の要点
がある。The present invention provides a paste material consisting of the above components, in which 2 to 5% by weight of sepiolite and 0.1 to 5% by weight of sepiolite based on the total solid content are used.
The key point in the composition is that it contains 0.4% by weight of glass fiber.
セピオライトはけい酸マグネシウム系の繊維状鉱物で、
特に精製して繊維長を調整したものが良好に適用される
。セピオライトの配合量を全固形分に対し２〜５重量％
に限定する理由は、２重量％未満では絡合性ならびに保
水性を向上させる効果が生ぜず、５重量％を越える配合
は前記効果の向上に寄与しなくなるためである。Sepiolite is a fibrous mineral based on magnesium silicate.
In particular, those whose fiber length has been adjusted through refinement are suitable. The amount of sepiolite added is 2 to 5% by weight based on the total solid content.
The reason for limiting the amount is that if it is less than 2% by weight, the effect of improving entanglement and water retention will not be produced, and if it is more than 5% by weight, it will not contribute to improving the above effects.
ガラス繊維には適宜の長さに裁断されたチョツプドファ
イバーが用いられるが、繊維長が長いはど又混入量が多
いほど補強効果が大きくなる。しかし、繊維の長さが１
５ｍを越えると材料の流動性が極端に悪くなってポンプ
の撹拌用羽根やパルプに絡み付いたり毛玉が発生する現
象が起き、他方１０ｍｍを下地ると補強性が減退する。Chopped fibers cut to an appropriate length are used as the glass fibers, and the longer the fiber length and the greater the amount of fibers mixed in, the greater the reinforcing effect. However, the fiber length is 1
If the length exceeds 5 m, the fluidity of the material becomes extremely poor, causing phenomena such as entanglement with the stirring blades of the pump or the pulp, or pilling, and on the other hand, if the length is 10 mm, the reinforcing properties decrease.
このため、１０〜１５−一の長さにすることが好適であ
る。For this reason, it is preferable to set the length to 10 to 15-1.
また、ガラス繊維の含有率は全固形分に対して０．１重
量％未満では絡合性が低下して補強効果が十分に発揮さ
れず、また０、４重量％を越える添加は材料の流動性を
損ねる結果を招く。したがって、全固形分に対して０．
１〜０．４重量％の範囲に設定する。In addition, if the content of glass fiber is less than 0.1% by weight based on the total solid content, the entanglement property will decrease and the reinforcing effect will not be sufficiently exhibited, and if the content exceeds 0.4% by weight, the material will flow. This results in harm to one's sexuality. Therefore, 0.0% based on the total solids content.
It is set in a range of 1 to 0.4% by weight.
上記の組成を有する本発明の耐火被覆材によれば、全固

。According to the fireproof coating material of the present invention having the above-mentioned composition, sepiolite and glass fiber in a specific range of amounts relative to the total solid content synergistically entangle the paste components to increase strength and improve water retention efficiency. This results in improvements in physical properties equivalent to or better than that of conventional asbestos. In particular, the combined use of glass fiber has the function of significantly increasing entanglement with the lath when spraying is applied to the lath base used for wall materials, etc.
このような作用を介して、常に良好な施工性でダレ、剥
落、亀裂等の欠陥がない高強度の耐火被覆面が形成され
