The present invention relates to a method for manufacturing a wood-based inorganic board used as, for example, an exterior wall base material. Conventionally, a wood cement board has been used as the wood-based inorganic board. To construct an exterior wall using this material, first, waterproof paper such as asphalt felt is pasted on the pillars and studs, then wood cement boards are fastened directly or through the edges of the paper, and caulking is applied to the joints. After application, it is formed by painting with acrylic resin paint, acrylic urethane paint, etc., or by finishing with mortar. However, this wood cement board has the following drawbacks. First, since the base material is a composite material of cement and wood, that is, the degree of paint absorption differs between cement and wood, so uneven paint absorption tends to occur and uniform application is difficult. Second, since the paint has high absorbency, the base material tends to warp or twist during curing and drying. Thirdly, if the moisture content of the base material is inappropriate or uneven absorption of paint or mortar causes damage to the adhesion of the paint film, repeated water absorption and drying may cause cracks in the finished painted surface and peeling of the paint film. Easy to occur. For this reason, it is necessary to pay sufficient attention to adjusting the moisture content of the base material and drying conditions. On the other hand, in order to improve the uneven absorption, the surface of the wood cement board base plate is sometimes treated with a sealer in advance. However, with this wood cement board, the sealer-treated layer becomes a hardened surface layer, so even if finishing paint or mortar is applied on top of this, the physical adhesive strength, or anchoring effect, is small, and due to poor adhesion, only a limited number of types are available. Finishing paints other than these have the disadvantage of being easy to peel off. The present invention was made in view of the above-mentioned drawbacks of the conventional art, and involves applying a mixture of aggregate, water and a hydraulic inorganic material onto a template, and applying a polymer dispersion thereon. By spraying a mixture of wood materials, water, and hydraulic inorganic materials on the surface of the paper, pressing them together and curing them, the adhesion of the paint film to the surface is good, and when installing external walls, waterproof paper can be used. The purpose of the present invention is to provide a method for manufacturing a wood-based inorganic board that makes it possible to eliminate the above steps. Next, the present invention will be explained. First, in the first step, a mixture of a hydraulic inorganic material, aggregate, and water is uniformly applied onto a template to form a mat layer. As a second step, a polymer dispersion is uniformly applied onto the matte layer. In the third step, a mixture of a hydraulic inorganic material, a wood material, and water is dispersed on the polymer dispersion layer to form a layer of an appropriate thickness. In the fourth step, the laminated mixture and the like are integrally pressed together and cured to form a wood-based inorganic board. Here, examples of the above-mentioned materials include the following. Hydraulic inorganic materials: cement, gypsum, calcium silicate. Aggregates...silica sand, river sand, calcium carbonate polymer dispersion...polymer emulsion, rubber latex Furthermore, polymer emulsion...ethylene-vinyl acetate copolymer emulsion, polyvinyl chloride emulsion rubber latex...styrene-butadiene rubber (SBR), nitrile butadiene Rubber (NBR),
Methyl methacrylate butadiene rubber (MBR), chloroprene rubber (CR) Wood materials...Fiber-like wood material, flake-like wood material, wood chips Each of the above in the first and third steps when cement is used as the hydraulic inorganic material The blending ratio (weight ratio) of the materials is as follows. 1st step: Cement: Aggregate: Water = 1:0.5-5: 0.4-0.8 3rd step: Wood material (completely dry): Cement: Water = 1:1.5-5:
1 to 2.5 In addition, if necessary, additives such as water retention agents and dispersants may be added to the mixture of the first and third steps, and in the second step, a polymer dispersant may be added to the matte layer. When the polymer dispersion is applied, the above aggregate is used as a filler to adjust the degree of penetration of the polymer dispersion into the pine layer and to maintain a high concentration of polymer dispersion on the pine layer. It may also be incorporated into polymer dispersions. In this case, the compounding ratio (weight ratio) is: filler:polymer dispersion (solid content)
50%) = 1: It is preferable to select within the range of 0.02 to 0.3. This aggregate is also used to bulk up the mixture, contributing to cost reduction.
If there is too much aggregate, the aggregate tends to peel off from the surface after the mixture dries, while if it is too little, cracks tend to form on the surface. Furthermore, in the first and second steps, known additives such as a curing accelerator and a waterproofing agent may be added. In the wood-based inorganic board manufactured by the above steps, the polymer dispersion is interposed between the layers formed in the first and third steps and functions as an adhesive layer. Further, in the second step, when the polymer dispersion penetrates into the matte layer formed in the first step, a concentration gradient occurs. Then, in the fourth step, each laminated layer is cured and molded as a unit while maintaining this concentration gradient, so even after curing, the concentration gradient of the polymer dispersion decreases toward the template side surface of the inorganic plate. A layer with . That is, the concentration of polymer dispersion on the surface of the inorganic plate on the template side is low, and a layer whose concentration increases from the surface toward the inside is integrally formed, forming a waterproof layer. For this reason, even if a finishing coat is applied to the inorganic board during exterior wall construction, the absorption of the paint is blocked by the polymer dispersion layer, eliminating uneven absorption and reducing the amount of absorption. Warpage, etc. will also be reduced. Furthermore, since the polymer dispersion acts as an adhesive layer, the adhesive strength between the surface layer and the inner layer of the inorganic plate is increased. Furthermore, since there is little polymer dispersion on the surface of the inorganic board, even if paint or mortar is applied on this surface, the anchoring effect will not be weakened.
Adhesion is good. Note that the surface of the template may be formed into an uneven shape, thereby improving the adhesion of mortar coating. Next, examples of the present invention will be described. First, the thickness is 3.5 mm with minute irregularities formed on the surface.
On a template made of aluminum plate, a mixture consisting of: 150 parts by weight of cement, 100 parts of calcium carbonate, 50 parts of silica sand (grain size 6), 1.5 parts of methyl cellulose (water retention agent), 90 parts of water was mixed with a ricing gun by about 0.5 parts by weight. It was applied uniformly to a thickness of mm. Then, on top of this, a mixture consisting of MBR latex (solid content 50%): 50 parts by weight, methyl cellulose: 1, calcium carbonate: 200, was applied uniformly to a thickness of about 0.5 mm. To, Hinoki Perlman Flake (blade length 0.35mm)
: 100 parts by weight (totally dry) Cement : 200 〃 Water : 150 〃 Spread a mixture, compact it at a pressure of 12 kg/cm 2 for 24 hours, cure it for 28 days after releasing the pressure, and make a thickness of 12
A wood-based cement board with a specific gravity of 1.0 mm and a specific gravity of 1.0 mm was obtained. Furthermore, in order to test the adhesion of the mortar layer on this cement board surface, a cement-based spraying material was applied on this surface to form a 10 mm thick layer.
After curing for one day, Sample A according to the present invention was obtained. On the other hand, a comparative sample B was obtained by applying the same cement-based spraying material as above onto a commercially available wood-based cement board without a surface treatment layer. As a result of examining the adhesion of the surface finishing layer (mortar layer) and the water permeability of Samples A and B, the following data were obtained.

(mm) steel plate is glued and pulled vertically.
The water permeability test was conducted by measuring the tensile load when the surface finishing layer was peeled off, and by measuring the amount of water permeating the sample per unit area per unit time. From the above data, it can be seen that Sample A has good adhesive properties and waterproof properties. By the way, the water permeability of normal waterproof paper felt is about 2×10 -3 g/cm 2 hr. As is clear from the above description, according to the present invention, a mixture of aggregate, water and a hydraulic inorganic material is applied onto a template, and a polymer dispersion, which is a resin, is applied on the template, and then a polymer dispersion, which is a resin, is applied on the template. A wood-based inorganic board is manufactured by spraying a mixture of a wood material, water, and a hydraulic inorganic material onto the board, and integrally pressing and curing the mixture. Therefore, a concentration gradient of the resin component is formed in the inorganic plate, increasing from the surface toward the inside, and even if paint, mortar, etc. are applied to the surface, the anchoring effect is maintained well and adhesion is good. In addition, the internal resin layer becomes a waterproof layer, and after construction of the exterior wall, rainwater is blocked by this waterproof layer, so waterproof paper for the base of the exterior wall can be omitted. Furthermore, since no wood material is mixed in the surface layer (template side) of the inorganic board, it has the effect of eliminating uneven absorption even when paint or the like is applied.
