The present invention is for architectural use, which is made by applying a surface treatment to a wood-based plate-like base material to prevent elution of components in the wood, then applying a synthetic resin paint, and then applying and solidifying a cement-based mixture. This relates to a method for manufacturing base materials. Traditionally, this type of base material has been manufactured by applying a synthetic resin adhesive solution, emulsion, latex, methylcellulose, vulcanized rubber solution, or By applying a resin paint such as polyvinyl alcohol, the adhesion between the wooden board and the cured cement material is facilitated, and the applied synthetic resin adhesive or paint forms a film on the surface of the wooden board. As a result, the alkali-soluble components (hemicellulose, cellulose, lignin, resin, etc.) in the wood planks that inhibit cement hardening are eluted into the cement slurry.
It worked to prevent the curing of cement slurry from being inhibited. However, according to the above conventional method, curing-inhibiting components in the wood may bleed into the applied adhesive or emulsion, contaminating the film, causing foaming during film formation, or causing small pinholes in the film. However, it is impossible to obtain a complete effect, especially when using wood with a high alkaline soluble content. Abnormalities such as poor hardening and discoloration of the applied cement mixture are often observed, making it difficult to obtain sufficient strength and appearance as a building material. At present, it has not yet been possible to obtain a composite plate having the following properties. In the present invention, wood components (cellulose, hemicellulose, lignin, pigments, resins, waxes) that are considered to inhibit the hardening of cement can be adsorbed, or wood components that can form salts with these components can be added to the wood base material in advance. The cement curing inhibiting components in the wood are inactivated by surface treatment, and then a synthetic resin paint such as a synthetic resin adhesive solution, synthetic rubber latex, synthetic resin emulsion, or bituminous emulsion is applied, and then a cement-based mixture is applied. The present invention relates to a method for manufacturing a base material for construction obtained by coating and solidifying. Next, the present invention will be explained in detail. FIG. 1 is a sectional view of a composite board for construction according to the present invention, and FIG. 2 is a perspective view thereof. In the figure, 1 is a wooden plate-like base material, 2 is an alkali or alkaline earth metal ion solution treatment layer, 3 is a synthetic resin adhesive or paint layer, 4 is a cement binding material, 5 is a lightweight aggregate, and 6 is a composite layer refers to Although there is currently no established theoretical explanation for the mechanism by which wood extracts inhibit cement hardening, the following reaction process is generally assumed. That is, the liquid phase of cement paste or mortar contains ions such as Ca 2+ , K + , Na + , SO 4 2- , OH - and has a fairly high pH, so alkaline eluted substances are eluted from the wood surface. Various substances can be eluted at this time, such as cellulose, hemicellulose, lignin, pigments, resins, and wax, but among these eluted substances, alkali or alkali such as Ca 2+ , K + , Na + Adsorption of earth metal ions or formation of salts with them is said to be the main cause of poor curing. Wood types that contain a large amount of cement hardening inhibiting components include Merapi, Mangashinoro, and
There are many types of wood such as merwasa, parosapis, barau, and resaku; North American wood is Japanese cedar; Japanese wood is oak, oak, zelkova, and red pine; South Sea wood is a tree species with a relatively low content of cement hardening inhibiting components. Woods include Letudrawan, Apitong, Yellow Seraya Tangir, Bakchikan, etc.; Northern Seawoods include Beihi, Beitsuga, Beimatsu, Beihiba, etc.;
Domestic materials include elm, nara, katsura, fir, karamatsu, totatsu, and ezomatsu. The effects aimed at by the present invention are particularly advantageously exhibited in the case of materials containing a large amount of the above-mentioned hardening inhibiting components. Examples of the wood base material used in the present invention include plywood, particle board, hardboard, flake board, and composite boards such as these. The surface of these wood-based substrates is preliminarily coated with a solution containing alkali and/or alkaline earth metal ions such as calcium hydroxide, potassium hydroxide, sodium hydroxide, etc., or with a solution containing alkali and/or alkaline earth metal ions such as boric acid, boron, etc. The cement hardening inhibiting components in the wood are inactivated by treatment with a solution containing substances that form complex salts with sugars, organic acids, lignin, etc. in the wood, followed by drying if necessary. 1 each of synthetic rubber latex, synthetic resin emulsion, bituminous emulsion, synthetic resin paint or synthetic resin adhesive consisting of a mixture thereof, or inorganic material particles or powder (talc, silica stone, etc.)
A mixture of more than one species is applied. After that, after drying for a short period of time if necessary, apply a cement slurry-based coating material that is a mixture of cement paste, cement mortar, glass fiber mixed cement, lightweight aggregate mixed cement, or the like. After that, a suitable curing period is provided to solidify the product, and if necessary, a drying process is performed to produce a product. According to the method of the present invention, the cement-based coating material is firmly integrated with the surface of the wood-based base material, and cement hardens at the interface between the wood-based base material and the cement-based coating material, which is particularly observed in wood species that contain a large amount of components that inhibit cement hardening. Since phenomena such as insufficient strength due to defects are not observed, it is possible to manufacture excellent architectural base materials. Next, the present invention will be explained in more detail with reference to Examples. Example 1 A 30% calcium hydroxide solution was applied to 7 mm thick, 910 mm wide, and 1820 mm long class I plywood (material type Merapy) that had been treated with antiseptic and insect repellent using a roll coater.
Apply 2 amounts of g/m and heat to 80℃. Dry for 5 minutes, then apply acrylic emulsion using a roll coater.
Apply 2 amounts of 250g/m and heat to 80℃. After drying for 5 minutes, ordinary mortar (sand/cement = 3/1, flow value 180) was evenly sprayed using a continuous ricing gun to a thickness of 5 mm, and allowed to accumulate and harden for one week. The obtained plywood-cement composite board did not lack strength due to insufficient hardening of the cement, and was suitable as a base material for construction. Example 2 300 g/m 2 of 30% potassium hydroxide solution was applied with a brush or brush to Class I plywood (wood type Resaku) with a thickness of 5 mm, width of 910 mm, and length of 1820 mm that had been treated with insect repellent and antiseptic treatment, and heated at 80°C. After drying for 10 minutes and then lightly sanding with #120 sandpaper, a mixture of acrylic emulsion and talc (weight ratio 1:1) was applied in two amounts at 400 g/m using a roll coater. 80℃. Let dry for 10 minutes. Thereafter, they were mixed in the proportions shown in the table below.
