の硬化剤を配合したものでもよい。The alkali metal silicate binder 2 may be made of an alkali metal silicate alone, or may be combined with an alkali metal silicate to impart water resistance to Erosil, carbon black, or fumed silicate having a particle size smaller than the fiber diameter of the reinforcement 11i11. Even those containing aggregates such as montmorillonite and/or hardening agents such as metal oxides, metal hydroxides, silicofluorides, phosphates, borates, etc. having a particle size smaller than the II fiber diameter of the reinforcing van'+. good.

維補強無機質製品を得る。Next, as shown in the second diagram, an organic binder such as epoxy, phenol, polyimide, vinyl ester, or polyester is applied to the entire surface of the reinforcing body 3.
Water-resistant composite binders containing, for example, alkali metal silicate binders and inorganic binders containing hardening agents such as metal oxides, metal hydroxides, silicofluorides, phosphates, and borates, etc. The water-resistant binder 4 is coated by dipping, coating 15, etc., and the coated water-resistant binder 4 is coated with a desired number of inorganic materials 5 such as cement and plaster in a hardened or unhardened state.
After that, the uncured inorganic material 5 is cured to obtain a fiber-reinforced inorganic product.
尚、前記の耐水性結合剤４は常温硬化型であっても加熱
硬化型であってもよい。Note that the water-resistant binder 4 may be of a room temperature curing type or a heat curing type.

It is preferable to concentrate the particles into a rod-shaped body having an irregular shape, since this increases the binding force with the inorganic material 5.

が得られる効果を有する。(Effects of the Invention) According to the present invention, a reinforcing fiber body made of reinforcing fibers bundled with an alkali metal silicate binder is coated with a water-resistant binder on the surface of the reinforcing fiber body, and the uncured cement is coated with the water-resistant binder. The reinforcing fibers are placed in an inorganic material such as plaster, and the uncured inorganic material is cured, so that the reinforcing fibers are tightly bound together by the alkali metal silicate binder with high adhesive strength. The water-resistant binder coated on the surface of the reinforcing fiber body prevents the alkali metal silicate binder from being dissolved by the water contained in the inorganic material and weakening the binding force between the reinforcing fibers. This has the effect of producing a fiber-reinforced inorganic product with excellent bending strength.
