It is used in architecture, civil engineering, and various industrial fields.

Among these insulation materials, organic foams are lightweight and have good insulation properties, but they are flammable and have extremely poor heat resistance. It is used only in areas where it is not necessary. On the other hand, inorganic fiber insulation materials such as glass fiber and rock wool are nonflammable, and compared to organic foams,
Due to its heat resistance, it is widely used in residential and industrial fields.

nr! JCm 'r'-Zonkyoku M1 If you rely on it, the fibers will soften or shrink in size, so although it is used as a heat insulating material in high temperature ranges, there are naturally limitations on the operating temperature (glass fiber insulating materials The current temperature is 600-400C (600-700C for rock wool insulation). Furthermore, these inorganic fiber spot heating materials have low resistance to chemicals such as acids and alkalis, and are not used as insulation materials in fields that require chemical resistance, or if they are used in this field, Construction methods are used that take into account protection using materials with excellent chemical resistance, resulting in problems such as complicated construction and a significant increase in construction costs.

[Purpose of the invention]

In view of the above-mentioned problems, the present invention has been developed by bonding an inorganic fibrous body with an inorganic material having excellent fire resistance and chemical resistance.
The aim is to obtain a product that has performance that can withstand a high temperature range of 0C.

[Summary of the invention]

The present invention involves dispersing an inorganic material made of at least two of titanium oxide, zirconium oxide, and silicon oxide and carbon black into a synthetic resin binder liquid and absorbing the inorganic material into an inorganic fibrous material. The inorganic fibrous material has high heat resistance and chemical resistance.

[Structure of the invention]

The inorganic material, synthetic resin binder liquid, and inorganic fibrous material that are nonflammable and impart fire resistance and chemical resistance, which constitute the present invention, will be described in detail.

Titanium oxide and zirconium oxide as inorganic materials include those produced by titanium compounds, zirconium compounds, and silicon compounds at a drying temperature of 200 to 300 C or by thermal decomposition during the manufacturing process. In the case of titanium compounds, there are diluted titanium, titanic acid, onitanium sulfate, titanium chloride, oxides such as titanium oxyacetylacetonate, titanium alkoxide, acids, inorganic salts, chlorides, organic titanium compounds, Zirconium compounds include zirconium oxide, zirconic acid, zirconium sulfate, zirconyl nitrate, zirconyl acetate, zirconyl oxychloride, zirconyl oxynitrate, zirconyl ammonium carbonate, zirconyl chloride, zirconium (Il17 cetyl acetonate, zirconium I alkoxide, etc.), and oxides. , acids, inorganic salts, chlorides, organic zirconium compounds, and silicon compounds such as silicon oxide, colloidal silicic anhydride, silicon tetrachloride, and organic silicon ammonium, acids, inorganic salts, chlorides, and organic silicon compounds. I can give it to you.

In addition to the above, inorganic materials include inorganic fillers such as clay, mica, talc, glass powder, magnesium hydroxide, aluminum hydroxide, ammonium polyphosphate, ammonium bromide, etc. as necessary to reduce costs. such as guanidine phosphate, silica phosphate, antimony trioxide,
There is no problem in adding organic or inorganic flame retardants to the extent that they do not impair fire resistance and chemical resistance.

Furthermore, carbon black as an inorganic material is a fine black powder and is usually commercially available such as furnace black, acetylene black, and thermal black manufactured by the furnace method, channel black, disk black, and German naphthalene black manufactured by the impact method. Further, it is also possible to use a type in which carbon black, which is obtained by treating inorganic fibers with carbon in a high-temperature reducing atmosphere, is fixed and integrated on the surface of the inorganic fibers. An example of this type is carbon black-fixed potassium titanate fibers. Furthermore, part or all of the carbon black may be replaced with a flame retardant that promotes carbonization of valves, resins, etc. contained in the inorganic fibrous material by heating during the manufacturing process.

Synthetic resin binders include vinyl acetate resin, ethylene/vinyl acetate resin, acrylic resin, synthetic rubber such as 8BR%NBR, emulsion type such as polyvinyl alcohol, starch, polyamide resin, polyimide resin, etc., aqueous solution type, and those dissolved in organic solvents. thermosetting resins such as solution types such as thermoplastic resins, melamine sticks, phenol resins, epoxy resins, polyester resins, furan resins, aqueous solution types, and solution types dissolved in organic solvents. They can be used alone or in the form of a mixture as a binder, but it is preferable to use water-soluble type or emulsion type binders due to the risk of fire.

Examples of the inorganic fibrous material include glass fibrous carp, rock wool fibrous material, and composite inorganic fibrous material made by combining these inorganic fibers. Glass fibrous material usually has a so-called E-glass composition to a C-glass composition, and is made of so-called short fibers with a twill fiber diameter of about 5 to 151 liters, in the form of a sheet, felt, mat, board, or cylinder. has the shape of
This is an inorganic fibrous medium in which the fibers are bound chemically using a small amount of a resin binder or mechanically by a method such as needling.

Rock wool insulation material is obtained by melting a raw material composition containing basalt, peridotite, iron ore slag, silica, dolomite, lime, etc., and turning it into fibers using centrifugal force such as a multi-rotor system. The shape and fiber bonding method are the same as those of the glass fiber type mentioned above. In addition, we can also produce non-bonded fibrous body/bills made by pressing the composite fibers of glass fibers and rock wool fibers in the same shape and bonding method as above, as well as glass fiber-based, rock wool-based, and glass fiber/rock wool composites. Saw machine fibrous material fibrous material made by partially blending organic substances such as valves, inorganic fillers, flame retardants, etc. to the inorganic fibrous material ￥ 1. Also includes. Note that it is effective to use a material having a bulk specific gravity of 0.5 or less, preferably 0.6 or less, from the standpoint of its heat insulation performance.

During production, the above-mentioned inorganic material is dispersed in the above-mentioned synthetic resin liquid, and this dispersion is absorbed into the above-mentioned inorganic fibrous material by impregnation or coating, followed by drying, followed by heating under pressure or no pressure. The inorganic material is bonded to the inorganic fibrous body by curing and, if necessary, heat treatment.

The mechanism of action of treating an inorganic fibrous body with the composition of the present invention to impart fire resistance and chemical resistance is completely clear. In the softening temperature range of fibers or rock wool, carbon black and the fibers are fixed and fired, and then titanium oxide, zirconium oxide, and silicon oxide react with carbon to form carbides on the fiber surface ( (The higher the temperature, the more carbides are formed.) As a result, the properties of these carbonates (high melting point, chemical resistance) are reflected, and the fibers are made non-combustible, fire resistant, and chemical resistant. It is estimated that this has become possible. There are no particular limitations on the blending ratio of the constituent components of the nonflammable, fire-resistant, and chemical-resistant composition of the present invention, but from the viewpoint of productivity and raw material cost, the preferred blending ratio is as follows: Silicon oxide + zirconium oxide + titanium oxide 35-7Qwt%, carbon black 5-1Qwt%, resin binder 10-5Qwt%,
Flame retardants and others are in the range of 0 to 10 wt%. Inorganic fibrous material K

Composition imparting fire resistance and chemical resistance 10 parts by weight
The amount is preferably 0 parts by weight or less. The Rinki fibers obtained by processing in this manner are usually dried at 60 to 110C, and then cured at 150 to 200C under pressure or without drying, depending on the resin binder. In order to harden under pressure and further to partially bake if necessary, the temperature is below the softening temperature of inorganic fibers (usually 2
By performing heat treatment at 50 to 800 C), it is possible to produce an inorganic fibrous heat insulating material that is nonflammable, fire resistant, and chemical resistant.

〔Effect of the invention〕

According to the present invention, an inorganic material consisting of at least two of titanium oxide, zirpnium oxide, and silicon oxide and carbon black is dispersed in a synthetic resin binder liquid and absorbed into an inorganic fibrous body. Because carbon black and two or more oxides are bonded to the surface of the fibers of the inorganic fibrous body, at least three types of inorganic materials each have different chemical resistance properties. A wide range of chemical resistance can be imparted. Furthermore, even if they become charred by encountering fire heat, they each have different heat resistance temperatures, so they can be imparted with heat resistance in different temperature ranges. Furthermore, since inexpensive carbon black, titanium oxide, zirconium oxide, and silicon oxide are used as inorganic materials, the material cost is low, and the overall cost can be reduced.
