にバラツキの多いものとなってしまう不利があった。Conventionally, many methods have been proposed for obtaining molded articles such as paper, boards, mats, tubes, rods, and blocks made of inorganic fibers and colloidal binders. For example, the simplest method is to directly apply or impregnate an inorganic fiber molded article with a suspension of colloidal 7-liquid. However, according to this method, Colloidal 7 Rica's Migray 7! The problem is that it is difficult to obtain a molded product with uniform hardness, and it is difficult to accurately control the colloidal silica fixation process. The disadvantage is that the quality of the molded products produced by this process varies greatly.

No. 279 discloses that after an inorganic fiber material is impregnated with colloidal silica, the colloidal silica is gelled by the action of a basic salt such as (NH4)lC01 or ammonia gas to prevent migration, drying and Baked and molded object 1! It is shown how to obtain However, in this method, the gelation process is troublesome, and it is difficult to sufficiently prevent migration and obtain a uniform bond of 1:1. Further, in US Pat. No. 5,224,927, cationic starch is added as a binding agent to an inorganic fiber slurry, then anionic colloidal silica is added, and rIR is further added to make the slurry pkl (-S~5
A method is shown in which a molded product is obtained by soaking the slurry in a slurry tF, and then drying it. However, in this method, it is difficult to fix all of the added colloidal silica on the fiber surface, and a considerable amount remains unfixed in the tS solution.

A selection is possible from the group consisting of fibers and mixtures thereof. Further, in order to improve the physical properties of the composition, a refractory inorganic substance or a combustible organic substance may be further included as necessary.

Ethanol, ethylene glycol, diethylene glycol, and mixtures thereof can also be used alone or in mixtures with water. The amount of dispersion medium is adjusted depending on the bulk of the fibers and the amount of colloidal 7-liquid, but it is necessary to have at least an amount that will sufficiently disperse the fibers. For example, it is preferably around 50 times (by weight) the amount of inorganic fiber.

Although the particle size is 0 millimicrons, particles with as small a particle size as possible are suitable for the present invention. This is due to the fact that the smaller the particle size, the stronger the bonding force.

すに至った。Here, "condensation" means bonding between silica particles. That is, the purpose of adding a coagulant is to add 1 on the surface of colloidal silica particles.
This is to lower the temperature and prevent agglomeration into polyethylene oxide. If a coagulant is not added, coagulation of colloidal silica into polyethylene oxide is almost impossible, and most of the colloidal silica is concentrated in the slurry while remaining attached to the fibers. It will remain. Therefore, the addition of coagulation-j is essential in the present invention.・ ・:: The most significant feature of the present invention is that colloidal silica particles are fixed on the surface of fibers using high molecular weight polyethylene oxide.As a result of various studies, we found that colloidal silica particles are coagulated using a coagulant, and then high molecular weight By adding polyethylene oxide, the colloidal silica can be almost completely fixed uniformly and firmly to the fiber surface, and based on this fact, the present invention was accomplished.

、コロイダルクリ力は殆んど完全に繊維に定着される。The high molecular weight polyethylene oxide used in the present invention is essentially nonionic, but as a result of the nine oxygen distributed in the chain forming an oxoni9 mucation association in an aqueous solution, the colloidal silica particles significantly aggregate with the polyethylene oxide, The colloidal silica aggregates and fibers are entangled in the slurry, and as a result, the colloidal force is almost completely fixed in the fibers.

Ｆｉクリカに対してＩ１１重量重量上が好ましい。The viscosity of the bath fluid varies greatly depending on the molecular weight of polyethylene oxide. Furthermore, the polyethylene oxide used in the present invention is limited to a molecular weight of about 100,000 or more, preferably 250,000 or more. The molecular weight is about 1
If it is less than 0,000, the fixation of colloidal silica to the fiber becomes extremely poor. Although it has not yet been theoretically elucidated, this is thought to be due to poor entanglement between the aggregates of colloidal silica and polyederene oxide and the fibers. For the same reason, it is preferable that polyethylene oxide has as few branches as possible, is linear, and has a long molecular chain. In addition, addition of polyethylene oxide 1i
It is preferable that the weight of I11 is higher than that of Fi.
