Description of the Invention (1) The present invention relates to the manufacturing method of calcium silicate board and the calcium silicate board obtained by this method. In the advanced technology, calcium silicate board has light weight *, excellent processability and dimensional stability, and is also non-combustible. It is widely used as a main building material for interior use. This is used as a building The widely used calcium silicate board forming method is generally used for manufacturing methods, mold pressing methods and single-layer forming methods. It consists of lime-based materials, silicic-based materials, inorganic fillers that reinforce susceptibility and lightweight bone materials, etc. The formed body formed from the raw material of the composition is made by the reaction of the saturated water vapor in the pressure vessel and hardened. 7〜 1.2 的之园内。 The volume specific gravity of this calcium silicate board is usually in the range of 0.7 to 1.2. 5〜0. 8 之轻 However, the use of calcium silicate board is used for interior materials such as patio materials, wall materials, etc., which are required to be as lightweight as possible, and in the above method, the bulk density is capable of being in the range of 0.5 to 0.5 The localizer must be matched with a relatively lightweight filler material, which causes the problem of low specific strength. In particular, in the papermaking method, for example, when a calcium silicate board is manufactured with a light weight of a volume specific gravity of 1.0 or less, the strength of the formed body before the hydrothermal reaction is weak and the water content is extremely large, so that the hydrothermal reaction occurs. The thermal expansion of the remaining water, the high strain of the steam, and the spalling between the ridges cause the problem of tilt. In order to prevent these problems, pressing is performed after forming, followed by hydrothermal reaction, or fixing with elastic screws in the hydrothermal reaction, but these methods will increase the bulk specific gravity and cause a lot of inconvenience. And troubles. Also, although the publication of JP 6- 2 8 7 0 8 3 contains the paper standard for removing residual water, the Chinese National Ladder (CNS) A4 specification (210 X297 mm) I, -------- --- > €-(Please read the precautions on the back before filling this page) • 丨 Line-4-A7 printed by Shellfish Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs ______B7_ V. Method of Invention Description (2) However, be sure to use a special pressure vessel or a steam superheater, so it cannot be solved by ordinary methods. In addition, raw materials containing calcareous raw materials and amorphous silicic acid raw materials have been gelled under normal pressure for weight reduction. However, this method cannot avoid reducing the strength, and because the material is soft, it is easy to grind. It causes shaving, causing excessive fluffing of the vitamin fibers, and the problem of surface smoothness damage after use occurs after coating. In addition, other methods are described in JP-A No. 5 2-1 0 5 9 2 6 and JP-A No. 5 2-1 3 5 3 3 0, in which a calcium silicate hydrate is added with hard silica calcium After the stone raw material or crystalline calcium raw material, a calcium silicate board having excellent strength is disclosed. However, this method has the disadvantage of requiring reduced manufacturing costs due to reduced productivity. Furthermore, the present inventors have disclosed in Japanese Patent Application Laid-Open No. 5-2 2 3 6 5 7 and Japanese Patent Application Laid-Open No. 7-4 1 3 5 In Bulletin 4, a method for adding a gelled raw material consisting of a calcareous raw material and an amorphous silicic acid raw material and a crystalline calcium silicate hydrate raw material to add both of them is found. A method of adding this gel is copied. The method will also cause problems such as peeling or tilting between layers of the composite board. In addition, Japanese Patent Publication No. 58-30259 discloses that a silicic acid raw material and a lime raw material are dispersed in water having a solid content of 15 times or more of these raw materials, and a mixture is obtained. The mixture is pressurized to a temperature of 130 ° C or more. After the heating reaction at the temperature, the sedimentary mass 稹 is more than 15 c m3 / g, and the calcium silicate-containing aqueous raw material formed by C-S-Η or xenolite is formed. Then add to the aqueous raw material Asbestos, after dewatering and forming, the paper size is applicable to China's national standard (CNS > Α4 size (2 丨 0X297 mm) under pressure.
