【発明の詳細な説明】
（産業上の利用分野）
本発明は建築物の床または壁のケーブル、配管（従来の
技術）
従来この種耐火性組成物としては、セメントと砂を主体
としたものが、主として使用されているのために解体を
必要とする場合例えば建築物等におけるケーブル貫通部
においては該ケーブルの周囲に該耐火物を直接流し込む
ことが出来ないため、複雑な貫通部の構造を形成しなけ
ればならず多大な労力と時間を必要とするものであった
。又コンクリートに解体性を容易にするためにセメント
、石膏系にバーミキュライト、及びアスベストを配合し
たものが出現しているが、このアスベストは人体に害を
あたえるおそれがあり公害上問題を生ずるものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to cables and piping for floors or walls of buildings (prior art). However, in cases where it is necessary to dismantle the cable because it is mainly used, for example, in a cable penetration part of a building, etc., it is not possible to directly pour the refractory material around the cable, so it is not possible to construct a complex structure of the penetration part. This required a great deal of effort and time. In addition, concrete containing vermiculite and asbestos in combination with cement and gypsum systems has appeared in order to make it easier to dismantle, but this asbestos poses a pollution problem as it can be harmful to the human body. .
（発明が解決しようとする課題）
本発明はかかる現状に鑑み鋭意研究を行った結果解体性
並に耐熱性に優れたモルタル状耐火組成物を開発したも
のである。(Problems to be Solved by the Invention) In view of the current situation, the present invention has developed a mortar-like refractory composition that is excellent in disassembly properties and heat resistance as a result of intensive research.
（課題を解決するための手段）
本発明はケイ酸ソーダ１００重量部に対し粘土５００〜
１５００重量部及び多孔性又は中空性無機粉末２００〜
１ｏＯｏｆｆｉ ｍ部ポルトランドセメントまたは石／
３９０〜２００重量部を配合し均一に混和したことを特
徴とするものである。(Means for Solving the Problems) The present invention provides 500 to 50 parts of clay per 100 parts by weight of sodium silicate.
1500 parts by weight and porous or hollow inorganic powder 200~
It is characterized in that 390 to 200 parts by weight of Portland cement or stone are blended and mixed uniformly.
本発明に使用するケイ酸ソーダとしては、粉末または水
溶液（水ガラス）のものであり、粉末状のものは他の配
合物と混和後、水を添加してモルタル状にすることが出
来うるが水ガラスの場合には水を添加する際に他の配合
物を同時に混和してモルタル状にしなければならない。The sodium silicate used in the present invention is in the form of a powder or an aqueous solution (water glass), and the powdered one can be mixed with other compounds and then made into a mortar by adding water. In the case of water glass, when water is added, other ingredients must be simultaneously mixed in to form a mortar.
その理由は水ガラス中の水とセメントまたは石膏とが反
応して保存することが出来ないためである。The reason for this is that the water in the water glass reacts with cement or gypsum and cannot be preserved.
きくしかも可塑水量の少い本節粘土が最も好ましい。Honbushi clay is the most preferable because it is hard and has a small amount of plasticizing water.
なお可塑性が小さい場合にはモルタルの施工性に欠け、
又可塑水量が多いとモルタルの硬化収縮が大きくなリヒ
ビ割れ、剥離の原因となり易いためである。この粘土は
火炎に接して高温になると焼結して強固な耐火物を形成
するためケーブル貫通部等に使用した場合延焼を防止す
ることが出来る。Furthermore, if the plasticity is low, the mortar will have poor workability.
In addition, if the amount of plasticizing water is large, curing shrinkage of the mortar tends to cause large cracks and peeling. When this clay comes into contact with flames and reaches a high temperature, it sinters and forms a strong refractory, which can prevent the spread of fire when used in cable penetrations, etc.
この粘土をケイ酸ソーダ１００重量部に対して５００〜
１５００重量部を配合する理由は５００重量部未満の場
合には高温における焼結力が弱く、又１５００重量部を
超えた場合には比重が大きくなり且水分の揮発が遅れ強
固にならないためである。Add this clay to 500 to 100 parts by weight of sodium silicate.
The reason for blending 1500 parts by weight is that if it is less than 500 parts by weight, the sintering power at high temperatures will be weak, and if it exceeds 1500 parts by weight, the specific gravity will increase and the volatilization of water will be delayed and it will not become strong. .
又本発明においてバーミキュライトやシリカバルンなど
の多孔性或は中空性無機粉末を添加する理由はモルタル
の比重を低下せしめ、解体性を良好にすると同時に硬化
時の収縮性をおさえ、火炎に接した際に熱膨張してモル
タル自体の収縮をおさえるためであり、該無機粉末とし
てはバーミキュライト、シラスバルーン、ガラスバルー
ン、シリカバルーン等を使用する。特に安価にして粒径
の大きいバーミキュライト及びシラスバルーンが好まし
い。In addition, the reason why porous or hollow inorganic powders such as vermiculite and silica balloons are added in the present invention is to lower the specific gravity of the mortar, improve disassembly properties, and at the same time suppress shrinkage during hardening, so that when exposed to flame, This is to suppress shrinkage of the mortar itself due to thermal expansion, and vermiculite, shirasu balloons, glass balloons, silica balloons, etc. are used as the inorganic powder. In particular, vermiculite and shirasu balloons are preferred because they are inexpensive and have large particle sizes.
この無機粉末をケイ酸ソーダ１００重量に対して２００
〜１０００重量部を配合する理由は２００重量部未満の
場合には上記の如き効果が薄く、又１０００重量部を超
えた場合にはケイ酸ソーダ及び粘土の結合力を弱めるた
め硬化後の構造を保持し難くなり自然に崩壊するおそれ
がある。200% of this inorganic powder per 100% of sodium silicate
The reason for blending ~1000 parts by weight is that if it is less than 200 parts by weight, the above effect will be weak, and if it exceeds 1000 parts by weight, the bonding force between the sodium silicate and the clay will be weakened, so the structure after hardening will be It may become difficult to hold and may collapse naturally.
又本発明耐火性組成物は上記の他に結合力を増強せしめ
るためにポルトランドセメントまたは石膏を添加しても
よく、これらは水との反応性がよいため硬化して強固な
ものになる。而してその配合量はケイ酸ソーダ１００重
量部に対し２００重量部未満を配合することが好ましく
、２００重量部を超えた場合には、著しく強化されて解
体に際し困難となるためである。In addition to the above, the fire-resistant composition of the present invention may also contain Portland cement or gypsum to enhance the bonding strength, and since these have good reactivity with water, they harden and become strong. Therefore, it is preferable to blend less than 200 parts by weight per 100 parts by weight of sodium silicate, because if it exceeds 200 parts by weight, it will be significantly strengthened and difficult to dismantle.
なおポルトランドセメント石膏を配合しない場合には水
との硬化反応が不十分であるため、ケイ酸ソーダとして
水ガラスを使用するとか或は水を配合して予めモルタル
パテ状にして保持することが出来る。Note that if Portland cement gypsum is not blended, the curing reaction with water is insufficient, so water glass may be used as the sodium silicate, or water may be blended and held in the form of a mortar putty in advance.
更に本発明耐火性組成物には着色材、増量材、補強用繊
維を少量添加してもよい。Furthermore, small amounts of colorants, fillers, and reinforcing fibers may be added to the fire-resistant composition of the present invention.
