ング材を得ることができたものである。The present invention is characterized by the use of sugar solution and hexit as binders, and by using the binders, a flexible fireproof packing material that maintains shape retention and moisture retention and has good workability. This is what I was able to obtain.
本発明において使用される無機耐火物粉末としては、通
常耐火物に使用されるマグネシア、アルミナ、シリカ、

きる。The inorganic refractory powder used in the present invention includes magnesia, alumina, silica, which is usually used for refractories,
Inorganic refractory powders such as clay and carbon can be used.

、合成繊維、くず等を挙げることが、できる。無機繊維
および有機繊維の長さは１０ｍｍ未満であることが混練
時の分散上望ましい。As the fiber raw material used in the present invention, inorganic fibers can be used alone, organic fibers can be used alone, or both can be used together. Examples of inorganic fibers include slag wool,
Examples of the organic fiber include asbestos, glass fiber, and ceramic fiber. Examples of the organic fiber include wood pulp, hemp thread, cotton waste, synthetic fiber, and waste. It is desirable for the length of the inorganic fibers and organic fibers to be less than 10 mm for dispersion during kneading.
無機繊維は常温時および中間温度の強度を与える作用が
あるが、該パッキング材の耐食性を低下させるのでその
添加量は３０重量部以下とするのが好ましい。Inorganic fibers have the effect of imparting strength at room and intermediate temperatures, but since they reduce the corrosion resistance of the packing material, the amount added is preferably 30 parts by weight or less.
有機繊維は常温時の強度およびパッキング材に保形性を

５重量部を超えると使用時の燃焼によって気孔を作り気
密性が低下し、また組織が脆弱化する等の欠点が生ずる
。Organic fibers provide strength at room temperature and shape retention to the packing material, and when used, burn up to increase pores and improve heat insulation. The amount added is preferably 5 parts by weight or less, and if it exceeds 5 parts by weight, pores are formed due to combustion during use, resulting in a decrease in airtightness and weakening of the structure.

The amount added is 5 to 15 parts by weight based on 100 parts by weight of the main raw material, depending on the target shape retention and pressure shrinkability.

キング材の気密性が得られない。The larger the amount of sugar solution added, the greater the plasticity and flexibility, but if it is less than 5 parts by weight, the shrinkability under pressure will not be sufficient and the packing material will not be airtight.

して施工後昇温、受鋼時に結合剤消失によるパッキング
材組織が脆弱化する等の欠点が発生する。Moreover, if it exceeds 15 parts by weight, the shape retention of the packing material will be poor and construction work will be difficult. As another type of hexite used as a binder, one or two hexahydric alcohols such as D-sorbitol, D-mannitol, and dulcitol are used.
If the amount used is less than 5 parts by weight, the packing material may have poor moisture retention properties and cracks may occur. If the amount exceeds 30 parts by weight, the packing material will have poor shape retention, and the structure of the packing material will become brittle due to temperature rise after construction and loss of binder during steel receiving.
なおヘキシットは水溶液として添加することもできる。Note that hexite can also be added as an aqueous solution.
また高温の強度を保持させるために小量の無機質の結合
剤、例えば水ガラス、硼酸塩、リン酸塩等を併用するこ
とも可能である。It is also possible to use a small amount of an inorganic binder, such as water glass, borate, phosphate, etc., in order to maintain the strength at high temperatures.

て得られる。The flexible fire-resistant packing material of the present invention can be obtained by molding the above-mentioned compound by conventional o-ger molding, or by roller molding in which clay is placed in a frame of a predetermined shape and the surface of the clay is shaped with a roller.
