本発明は不定形耐火物、特に流し込み可能な濃密な不焼
成耐火物及び流し込み可能な不焼成軽量耐火物に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to monolithic refractories, particularly castable dense unfired refractories and castable unfired lightweight refractories.
不定形耐火物の主なるものとしては、キャスクプル耐火
物とプラスチック耐火物が従来より使用されている。Cask pull refractories and plastic refractories have conventionally been used as monolithic refractories.
キャスタブル耐火物は、耐火性の骨材にアルミナセメン
トなどの耐火性セメントラ配合して水と混合して流し込
んで使用されるのが一般的である。Castable refractories are generally used by mixing refractory aggregate with refractory cement, such as alumina cement, and pouring the mixture with water.
しかし、アルミナセメントを多量に使用するため、耐火
性、耐蝕性の高い骨材を使用しても、充分にその効果が
生かされていない。However, since a large amount of alumina cement is used, even if aggregate with high fire resistance and corrosion resistance is used, its effects are not fully utilized.
また硬化までに数時間〜２０時間程度かかり脱型までの
時間がかかりすぎる事等の問題点がある。Further, there are problems in that it takes several hours to about 20 hours to cure and it takes too much time to demold.
またプラスチック耐火物は耐火性の骨材に粘土等のバイ
ンダーを用いて練土状にしエヤーランマー等で成形する
ものが一般的なものであり、骨材の性能を極端に低下さ
せる事はないが、流し込み成形が出来ず、エヤーランマ
ーを使用するための作業上の問題点もある。In addition, plastic refractories are generally made by using fire-resistant aggregate with a binder such as clay, kneading it into a clay shape, and molding it with an air rammer, etc., and this does not significantly reduce the performance of the aggregate. Cast molding is not possible, and there are operational problems as an air rammer is used.
本発明は、これ等の問題点を解決し非常に少ないセメン
ト量で流し込み可能な不定形耐火物を供するものである
。The present invention solves these problems and provides a monolithic refractory that can be poured with a very small amount of cement.

メント量が５〜８ｏｌ）と末だ多く、（２）に於いては
硬化時間が長いと云う問題点も有している。Castable monolithic refractories using a small amount of alumina cement include (1) Japanese Patent Publication No. 51-9770, (
2) Although it is shown in Japanese Patent Application Laid-Open No. 127907/1983, it is fundamentally different from the present invention, and (1) has a much larger amount of cement at 5 to 8 ol), and (2) However, there is also the problem that the curing time is long.
一般に流し込み用不定形耐火物は施工現場で混練して流
し込むまでに、３０〜６０分程度の作業時間が必要であ
り、更に流し込み後は出来るだけ早く硬化脱型出来る事
が望ましく、またそのまま炉壁等の構造体となるので流
し込み後の収縮率が出来るだけ小さい事が望ましい。In general, casting monolithic refractories requires about 30 to 60 minutes of work time to mix and pour at the construction site, and it is desirable to be able to harden and remove the mold as soon as possible after pouring. Therefore, it is desirable that the shrinkage rate after pouring be as small as possible.
本発明はまた従って添加水量が少なくてすみ、流し込み
後の収縮率が従来よりも小さく、強度も有する不定形耐
火物を供するものである。The present invention also provides a monolithic refractory that requires less water to be added, has a smaller shrinkage rate after pouring than conventional refractories, and has strength.

。In order to satisfy these requirements, the present invention contains 80 to 100 parts by weight of fire-resistant aggregate, and 20 parts by weight or less of a workability-imparting material consisting of one or both of fire-resistant clay and fine powder of fire-resistant aggregate. When constituting a monolithic refractory by mixing 2 to 4 parts by weight of alumina cement and water to 100 parts by weight of the fire-resistant aggregate and workability imparting material, a type of styrene or pH 9 of a basic salt of a mixture of oligomers formed by reacting two or more types with one or more types of maleic acids and having a molecular weight of 20,000 or less

5°C, cps) Resin aqueous solution (hereinafter referred to as water-soluble styrene maleic resin) with a resin content of 35 weight φ 0.1 to
By adding 10 parts by weight or 0.05 to 2 parts by weight of sodium pyrophosphate together with the water-soluble styrene maleic resin, the amount of water added can be reduced, and the time required for casting and demolding after kneading can be reduced. The time required for the refractory to become wet can be set arbitrarily, and a monolithic refractory with low shrinkage and high strength can be obtained.
本発明は軽量耐火性骨材を耐火性骨材の一部又は全部に

とを見出したものである。In the present invention, a lightweight monolithic refractory can be made by using a lightweight fire-resistant aggregate as part or all of the fire-resistant aggregate, but the lightweight fire-resistant aggregate is not used and granular expanded polystyrene is added to the above formulation. It has been discovered that by blending it with scales, a lightweight fireproof and insulating wall can be created.

構造体を得るものである。That is, a small amount of alumina cement and a small amount of water-soluble styrene-maleic resin, or a small amount of pyrophosphoric acid Nogu, are added to the fire-resistant aggregate and workability imparting material, which are mixed in particle size, and poured with as little water as possible suitable for the pouring operation. The mixture is kneaded, poured into a furnace wall, etc., and cured for an appropriate period of time to obtain a structure such as a furnace wall.

乾式混合する。More specifically, particle size combinations such as alumina, alumina-siliceous, silicic acid, magnesia, zirconia, etc. (generally have a continuous particle size with a maximum particle size of 10 to 3 mr++, and particle size combinations to achieve close packing) refractory aggregate (
When obtaining lightweight monolithic refractories, use fire-resistant lightweight aggregates instead of fire-resistant aggregates, or use granular foamed polystyrene or other materials with low calorific value and combustion gas volume as fire-resistant aggregates in advance. (It is also possible to reduce the weight by mixing a pore-imparting material and applying it to the furnace wall, etc., and then burning it down.) For 80 to 100 parts by weight, fine powder of fire-resistant clay or refractory aggregate is added as a workability-imparting material. Add up to 20 parts by weight, and then add alumina cement to be cured by reacting with the styrene maleic resin, and dry mix.
この場合アルミナセメントはＪＩＳＩ号、２号品あるい
はアルミナ含有量７０〜８０重量饅のハイアルミナセメ
ントのいずれを使用しても良く、経済性及び目的とする
耐火性によって決められる。In this case, the alumina cement may be JISI No. 2, JISI No. 2, or high alumina cement with an alumina content of 70 to 80% by weight, which is determined depending on economic efficiency and desired fire resistance.

If it is less than 2 parts by weight, the strength of the cured product will be insufficient, and if it is added in large quantities, CaO in the amorphous refractory material will increase and the heat resistance and corrosion resistance will deteriorate. is an appropriate amount.

してまた充填性をよくするために必要であるが、耐火性
骨材８０重量部に対し２０重量部以上を添加すると強度
が低下し耐火性も低下するので２０重量部以下とするも
のである。The workability imparting material is necessary to give fluidity to the refractory aggregate, serve as a binder, and improve filling properties, but if 20 parts by weight or more is added to 80 parts by weight of the refractory aggregate, the strength will increase. The content should be kept at 20 parts by weight or less since the fire resistance also decreases.
作業性付与材は、耐火性骨材の粒度分布や本発明不定形
耐火物の使用場所により全く添加しなくてもよい場合も
ある。The workability imparting material may not need to be added at all depending on the particle size distribution of the refractory aggregate and the location where the monolithic refractory of the present invention is used.

計１００重量部に対し０．１重量部以下の添加では殆ん
ど添加した効果が現れず、０．１重量部以上添加するこ
とにより鋳込成型可能時間、及び脱型可能になるまでの
時間を次第に長くできる。Water-soluble styrene maleic resin reacts with alumina cement and changes the time required for casting and demolding. Addition of 0.1 part by weight or less will hardly produce any effect, and addition of 0.1 part by weight or more can gradually lengthen the time required for casting and mold removal.
１０重量部も添加すれば３時間半位まで鋳込成型可能時
間を延ばすことができるが、現在の価格が高価であるの
でこのように多量の添加は経済的でない。If 10 parts by weight is added, the casting time can be extended to about 3 and a half hours, but since the current price is high, it is not economical to add such a large amount.
ピロリン酸ソーダーは硬化時間調節剤として単独の添加

である。Sodium pyrophosphate has no effect when added alone as a curing time regulator, but when added together with water-soluble styrene maleic resin, it has the effect of regulating the time required for cast molding and the time required for demolding. is 0.05 to 2 parts by weight per 100 parts by weight of the fire-resistant aggregate and workability imparting material.
これより多量に添加すると流し込み成形に必要とする以
上に鋳込成型可能時間が長くなり、またナトリウムを含
有するから耐火度を低下させるので好ましくない。If it is added in a larger amount than this, the casting time becomes longer than necessary for casting, and since it contains sodium, it lowers the fire resistance, which is not preferable.

を向上できる。In addition, as shown in the reference example, conventional monolithic refractories have a short time for casting and are inconvenient to mold, and take a long time to be demolded and take time to complete construction. According to the method, the time required for casting can be made sufficient for molding, and demolding can be done quickly, so construction efficiency can be improved compared to the conventional method.
