いる。[Prior art] Conventional wood cement boards, such as wood wool cement boards, wood fiber cement boards, and pulp-mixed cement boards, have excellent heat insulation properties, sound absorption properties, moisture absorption and desorption properties, bending strength, etc. as building materials. However, in terms of fire resistance, even if various efforts are made to make it AM-resistant, since wood wool, wood fiber, pulp, etc. are used as raw materials, it is difficult to make it completely non-combustible, and it is difficult to achieve fire resistance under the Building Standards Act. As a quasi-noncombustible material, its uses and installation locations are limited compared to noncombustible materials. The only way to make wood cement boards, etc. nonflammable is to reduce the mixing ratio of wood materials such as wood wool, wood fibers, and pulp to 1.
Even wooden materials can be made non-combustible by reducing the usual 35% by weight to 10% by weight or less and using a flame retardant, etc. However, when the amount of wooden materials is reduced to this extent, the quality of wood cement boards increases. It is difficult to put it into practical use because its properties such as heat insulation, sound absorption, moisture absorption and desorption properties, and workability due to its light weight are considerably inferior. For this reason, even if wood-cement boards have flame-retardant properties, the use of flammable organic materials is restricted depending on the construction site and its use, and the use of inorganic materials as non-combustible materials is restricted. The use of asbestos cement boards and lightweight aerated concrete panels has been forced.

Mix with the agent. As the binder, gypsum, magnesium carbide, etc. other than the above-mentioned cement may be used, and as the combustion inhibitor, there are those that suppress the combustion rate and those that suppress the calorific value, such as antimony dioxide and lead monoxide. , ammonium hydrogen phosphate, barium sulfate, etc. suppress the combustion rate by combining with oxygen in the air through thermal decomposition, and produce magnesium hydroxide.

It is effective to use a combination of one or more of the substance and the calorific value suppressing substance. After the cement and the combustion suppressant are evenly applied to the surface of the wood strips 2, the wood strips 2 are poured into a mold or pressure-molded and hardened and dried to become the non-combustible wood board 1.

ある。The alkali silicate or silicic acid compounds such as silicic acid hydrates, colloidal silicic acid, and silicic acid gel penetrate into the cell walls inside the wood material and adhere to the surface, and when dried, form a ceramic integrally with the wood material and solidify as it is. do. The wood chips 2 made into ceramic by this silicic acid treatment are very similar to naturally produced silicified water, that is, the silicic acid formed by trees underground, and can be said to be equivalent in that they are particularly excellent in nonflammability. It is.

できた。[Operations and Effects of the Invention] As detailed above, according to the present invention, non-combustibility could never be achieved with conventional wood cement boards, but by applying silicic acid treatment to the wood material and making it ceramic. By using artificial silicified water, adding a combustion inhibitor, and solidifying it with cement, we were able to achieve a temperature of 800°C or less for 20 minutes, which is the standard for noncombustible materials under the Building Standards Act, and thereby achieve noncombustibility.

ある。In other words, by converting the wood material itself into a ceramic, the wood material, which is originally flammable, is turned into a ceramic material with excellent heat resistance and non-combustibility.Additionally, a combustion rate suppressing substance and a calorific value suppressing substance are added to create a non-combustible inorganic cement. By attaching
Even if the content of the wood material in the conventional wood cement board is about 35% by weight, it fully satisfies the nonflammability standard.

いる。Since the wood has many pores between each other, it has excellent heat insulation and sound absorption properties.Furthermore, even though it is made of ceramic, the wood is porous, so it has moisture absorption and desorption properties, and it also has bending strength. It also maintains the same characteristics as before.

従って、本発明による不燃木質板は、前記した優れた特
性に加え、特に不燃化したことによる火災に対する安全
性を十分発揮できるのは勿論のこと、この安全性により
従来不可能とされた施工個所における木質セメント板の
使用用途の一層の拡大を図ることができるものである。4゜Therefore, in addition to the above-mentioned excellent properties, the non-combustible wood board according to the present invention not only has sufficient fire safety due to its non-combustibility, but also has a level of safety that was previously considered impossible. This makes it possible to further expand the uses of wood cement boards at construction sites.
