[Detailed description of the invention] Magnesia grains, dolomite grains, etc., alkaline earth metal oxides, preferably NIgO, CaO or 50 h#,
When using a substance that accounts for more than % as a refractory aggregate,
In the past, the use of water or aqueous binders was often inappropriate. The reason for this is that these aggregates promote water digestion or steam oxidation, resulting in significant damage to refractories.

However, compared to non-aqueous binders, water or aqueous binders have the advantage of being easier to use, less harmful to the working environment, and without the risk of fire. The emergence of a fire-resistant composition containing a binder has been awaited.

The present inventors have arrived at the present invention as a result of repeated studies in view of the above circumstances. That is, -CooH in the molecule
It has been discovered that an organic acid monomer having one or more groups and/or a polymer thereof forms a coordinate bond with an alkaline earth metal oxide in the presence of water and acts effectively as a binder, We have arrived at the present invention.

That is, the present invention provides a refractory aggregate in which an alkaline earth metal oxide and/or hydroxide accounts for 50% by weight or more of the refractory aggregate component, and an organic acid having one or more -Cook-T groups in the molecule. This is a fire-resistant composition composed of one or more monomers and/or polymers thereof.

In light of the spirit of the present invention, the fireproof composition of the present invention is not limited to the ingredients listed in the claims, but includes conventionally used clays, cements, silicates, borates, phosphates, etc. It is clear that this does not inhibit the combined use of acid salts, sulfates, phenol resins, etc.

Examples of monomers and polymers of organic acids having one or more -CooH groups in the molecule include unsaturated carboxylic acids and their polymers such as acrylic acid, methacrylic acid, and maleic acid, oxalic acid,
Examples include organic acids such as citric acid, tartaric acid, malic acid, malonic acid, and glyceric acid.

When these organic acids are ionized when MgO or CaO comes into contact with water to form a hydrate, they form a coordinate bond as -C0θper-. For example, acrylic acid has one -Coo)I group in one molecule and is a m-dentate ligand, but it has polymerizability, so it polymerizes and acts as a multidentate ligand as a whole. This is thought to be because it takes the form of one type of ionomer resin. Furthermore, since tartaric acid and the like are polydentate ligands having two -Coall groups and two -0H groups in one molecule, it is thought that the coordinate bonds are congested to form a huge network structure.

Since this bonding fully progresses at room temperature, it acts as a hard binder at room temperature. □For this reason, the refractory composition of the present invention can be used as a mortar for bricks with low water absorption such as electroformed bricks, dense bricks, and graphite unfired bricks, to eliminate joints that occur due to the long setting time of conventional water-based mortars. It is possible to eliminate the drawbacks such as a decrease in thickness and to shorten the setting time. Also, as a pourable material, it retains its shape in a short time after molding, so demolding time is shortened, contributing to improved workability.
