いという欠点がある。However, regarding the amorphous refractory obtained using each of the above resins, those using epoxy resin, melamine resin, acrylic resin have no residual carbon, no carbon bond can be obtained, and curability is good, but used I can't wash with water afterwards,
Furan resin has drawbacks such as difficulty in cleaning the mixer, and it is odorous, irritating, and expensive. Further, the phenolic resin has the drawbacks that the novolac type does not have thermosetting property and does not have room temperature curing property, and the resol type does have room temperature curing, but the winter curing is very slow, and the change with time is fast, and it cannot be stored for about one month. is there.
一方特公昭59−53232号公報記載の一連のレゾルシンホ
ルムアルデヒド樹脂は水溶性であり、残留炭素がある利

速度が遅いのを解消することができた。Therefore, the present inventors have used resorcinol-based resin (Nagoya Yushi Kagaku Co., Ltd., trade name DFK), which uses alkylresorcinol as a binder, which is produced during dry distillation of oil sire
Surprisingly, it was possible to eliminate the above-mentioned drawbacks, especially the slow curing rate in winter, unlike the resorcinol-formaldehyde resin by using a resin.

多孔になり過ぎるため好ましくない。The amount of the DFK resin of the present invention is 100 parts by weight of the refractory aggregate,
1 to 100 parts by weight is preferable. If it is less than 1 part by weight, the amount of carbon forming the bond of the amorphous refractory is small and the strength becomes insufficient, which is not preferable. On the other hand, if it exceeds 100 parts by weight, the refractory aggregate separates and precipitates, and the structure after heating becomes too porous, which is not preferable.

く、作業上問題が生ずるので好ましくない。The aldehyde donor used in the present invention is required for room temperature curing of DFK resin. Formalin and paraform can be used as the aldehyde donor. Hexamethylenetetramine can also be used if heat curing is desired. The compounding amount of the aldehyde donor is 0.1 to 20 parts by weight based on 100 parts by weight of the DFK resin in terms of aldehyde. If it is less than 0.1 part by weight, the curing rate in winter is slow and the curing strength is insufficient, which is not preferable. 20
If it exceeds 5 parts by weight, the curing will be too fast, the pot life will be short, and problems will occur in operation, which is not preferable.
