原料として竹繊維を使用する竹繊維補強無機質成形体に
関する。TECHNICAL FIELD The present invention relates to a wood-based inorganic molded body, and more particularly to a bamboo fiber-reinforced inorganic molded body that uses bamboo fiber as a wood raw material.

せることにより製造されている。[Prior Art / Problems] A wood-based inorganic molded body is usually obtained by kneading a wood raw material obtained by processing wood into flakes, wood wool, wood fibers, etc., and various cement or hydraulic hydraulic binder such as hydraulic gypsum and water. It is manufactured by molding this kneaded material and then curing and hardening the obtained molded body.

かった。Various kinds of coniferous trees and broad-leaved trees are widely used as a wood raw material, and it has been proposed to use bamboo as a wood raw material. Bamboo is a promising resource because it grows faster than conifers and hardwoods. Bamboo is also a promising wood raw material because it is tough and highly elastic,
Conventionally, bamboo fiber or the like is simply used in place of wood fiber or wood flake, which lacks specificity and does not fully utilize the toughness and elasticity of bamboo material.

すものではなかった。The present inventors have already proposed a technique of using bamboo as a wood raw material for a wood-based inorganic molding (Japanese Patent Laid-Open No. 26854/1990,
However, these techniques are aimed at improving the moldability and preventing springback in the production of an inorganic plate when bamboo fiber is used as a raw material. It did not take advantage of the characteristic of being highly elastic.

The present invention has been completed by finding means for easily solving such problems.

り強くないために高強度は得にくい。[Operation] The present invention is a fiber obtained by vertically defibrating bamboo as a main wood raw material of a wood-based inorganic molded body, and a long fiber component having a fiber length of 20 cm or more and an average diameter of 3 mm or less in a dry weight ratio. 6
It consists of using fibers containing 0% or more and 5% or more of short fiber components having a fiber length of 1 cm or less and an average diameter of 2 mm or less. As a result, it becomes possible to obtain a bamboo fiber-reinforced inorganic molded body having high strength and excellent toughness as compared with a conventional wooden inorganic molded body using wood fibers. That is, in order to obtain the various properties of the wood-based inorganic molded body, it is desirable that the wood raw material be fibrous as a form of the wood raw material, and that the fiber composition is mainly composed of long fibers having high strength and high toughness. However, in the case of conventional wood fibers, it was difficult to obtain long fibers with high strength. For example, as wood-based long fibers, there is wood wool that is used in wood wool cement boards, etc., but this is obtained by scraping wood to make wood wool. It is difficult to obtain strength.
また、強度を高めるため、高圧成形した場合、木毛どう
しが重なりあった部分が破壊され易くなり、このため比
重を高めても余り強度が上昇しないなどの問題もある。
この点、竹材を解繊すれば高強度の長繊維を容易に得ら

る。In addition, when high-pressure molding is performed to increase strength, the portions where the wooden hairs overlap each other are easily broken, and therefore, there is a problem that the strength does not increase so much even if the specific gravity is increased.
In this regard, by defibrating the bamboo material, high-strength long fibers can be easily obtained, so that it is possible to improve the drawbacks of conventional wood fibers.

に性能が低下するために好ましくない。In order to obtain a bamboo fiber-reinforced inorganic molded body having high strength and excellent impact resistance, it is necessary to use a long fiber component having an average fiber length of bamboo fiber of 20 cm or more and an average fiber diameter of 3 mm or less. . When the average fiber length is less than 20 cm, both strength and impact resistance decrease. Further, if the average fiber diameter exceeds 3 mm, the moldability is deteriorated, the surface accuracy of the molded body is deteriorated, and the performance is deteriorated, which is not preferable.

る。Even if only bamboo fibers having an average fiber length of 20 cm or more and an average fiber diameter of 3 mm or less are used, it is possible to obtain a bamboo fiber-reinforced inorganic molded article having a low raw material cost and excellent performance, but with a good moldability. It's not always good. Therefore, in the present invention, in order to further improve moldability while maintaining high performance at low raw material cost by using bamboo fiber, the long fiber component is 60% or more in dry weight ratio, and the short fiber component. In a dry weight ratio of 5
By using a fiber containing more than 100% as a wood raw material,
By the reinforcing effect of the long fiber component and the filling effect of the short fiber component, a molded product having high strength and excellent impact resistance can be obtained, and at the same time, the highly uniform molded product can be easily molded by the filling effect of the short fiber component.

くない。また、木質原料中の短繊維成分が５％未満であ
ったり、平均繊維径が2mmを超えると充分な充填効果が
得られず、成形性の改善にはつながらない。In the present invention, if the condition that the long fiber component is 60% or more and the short fiber component is 5% or more is satisfied, there is no problem even if the fiber length is more than 1 cm and less than 20 cm. Absent. However, the average fiber diameter must be 3 mm or less. On the other hand, the percentage of long fiber components in wood raw materials is 60%
If it is less than the above range, the strength and impact resistance are deteriorated, and if the average fiber diameter of the long fiber component exceeds 3 mm, the moldability is deteriorated, the surface accuracy of the molded body is deteriorated and the performance is deteriorated, which is not preferable. Further, if the short fiber component in the wood raw material is less than 5% or the average fiber diameter exceeds 2 mm, a sufficient filling effect cannot be obtained, which does not lead to improvement in moldability.

The blending ratio of bamboo fiber and inorganic hydraulic binder can be applied in the range of 1/20 to 1/1 in weight ratio.
