Description of the Invention [Technical Field] The present invention relates to a humidity-conditioning building material, and more particularly to a humidity-conditioning building material having improved surface stain resistance. [Previous Art] The building material itself has a humidity-controlling building material with a humidity-controlling function, and is a building material obtained by solidifying a material having moisture absorption and desorption such as zeolite or diatomaceous earth by a coagulating hardening agent such as cement or gypsum. Mixed and fired building materials. Specifically, a diatomaceous earth-based humidity-controlling building material is proposed in Japanese Laid-Open Patent Publication No. Hei-4-354514, and a zeolite-based humidity-conditioning building material is proposed in Japanese Laid-Open Patent Publication No. Hei No. Hei. In addition, Japanese Unexamined Patent Publication No. Hei No. Hei No. Hei No. Hei No. 35 1 9004 (Japanese Patent No. 35 1 9004) describes a humidity-controlling building material whose surface has been subjected to glaze application, which is glazed to enhance the pattern and can be made at the same time. It is a humidity-regulating building material with improved stain resistance. The surface of the humidity-conducting building material is glazed, so that various types of decorations can be imparted by the glaze, and the range of the style can be expanded. In addition, it is difficult for the dirt such as hand scale to adhere to the glazed surface, and even if the dirt adheres, it can be easily removed, so that the surface can be kept clean. This glazing is performed by forming a glass layer by a glaze by an area of 90% or less of the surface of the main body of the humidity-control building material, or by glazing the maximum thickness of the glass layer to 300 Å or less. The post-humidification building material has a humidity control performance of 80% or more of the body of the humidity-controlling building material before glazing. In JP-A-2003-247316, it is described that a moisture absorbing layer and an anti-fouling coating layer are formed on the surface of a building base 201235330, and a synthetic resin other than a poly-xyloxy emulsion and a poly-xyloxy emulsion is used. The top coat of the emulsion forms this top coat. Further, regarding the synthetic resin emulsion other than the polyoxyxanthene emulsion, a fluororesin emulsion is also recorded (paragraph 0020). [Prior Art Document] [Patent Document 1] Japanese Patent Laid-Open No. Hei 4-354514 [Patent Document 2] Japanese Patent Laid-Open No. Hei 3-109244 [Patent Document 3] Japanese Patent Laid-Open No. Hei 11-315586 [Patent Document 4] [Problem to be Solved by the Invention] The main body of the humidity-controlling building material is porous, so that the dirt is likely to adhere, and it is easy to infiltrate when the liquid-like dirt adheres. In addition, when the dirt adhered by the rag or the like is wiped, the dirt, the water adhering to the rag, the detergent component to be infiltrated into the body of the humidity-conducting building material, and the scale is enlarged. As in the above-mentioned Patent Document 3, the antifouling property of the humidity-controlling building material can be improved by providing the glaze layer, but in order to allow the body of the humidity-control building material to absorb and release moisture, the glaze layer is exposed to expose a part of the body of the humidity-controlling building material. It is partially set or set in a thin layer in the way of the atmosphere. Therefore, the dirt will directly adhere to the exposed portion of the body of the humidity-conducting building material. As in Patent Document 4, by using a fluororesin emulsion as an overcoat layer to improve the antifouling property, it is desirable to further improve the antifouling property. -6 - 201235330 An object of the present invention is to provide a humidity-conditioning building which is excellent in humidity control property and anti-fouling property. [Means for Solving the Problem] The humidity-controlling building material of the present invention has an antifouling layer containing a fluorine-based oil-repellent agent and inorganic fine particles on the surface of the main body of the humidity-controlling building material. The inorganic fine particles are preferably at least one of colloidal cerium oxide, alumina sol and fumed cerium oxide. The antifouling layer preferably contains 8 to 39% by weight of the fluorine-based oil-repellent agent, 17 to 52% by weight of the inorganic fine particles, and 24 to 70% by weight of the binder resin. A glaze is applied to the surface of the body of the humidity-controlling building material, and a glass layer produced by the glaze is formed in an area of 50 to 90% of the surface of the body of the humidity-controlling building material, and the moisture absorption and desorption performance system of the 24-hour cycle is It is preferably 1 50 g/m 2 or more. A glaze is applied to the surface of the body of the humidity-controlling building material, and the maximum thickness of the glass layer produced by the glaze is 3 ΟΟμηη or less, and the absorption and desorption performance of the 24-hour cycle is preferably 150 g/m2 or more. [Effect of the Invention] In the present invention, an antifouling layer containing a fluorine-based oil-repellent agent is formed on the surface of the main body of the humidity-controlling building material, and even if the dirt adheres to the anti-fouling layer, it is possible to prevent or inhibit the penetration of the dirt into the body of the humidity-controlling building material. Further, the adhered dirt can be easily wiped by a rag or the like. When this wiping is performed, it is also possible to prevent or suppress the penetration of water or detergent components contained in the rag or the like into the body of the humidity-controlling building material. 201235330 In the present invention, the antifouling layer contains inorganic fine particles such as at least one of colloidal cerium oxide, alumina sol, and fumed cerium oxide, and thus may be in the antifouling layer due to the presence of the inorganic fine particles. A fine vent hole portion is formed therein, whereby moisture can smoothly pass through the antifouling layer, and the humidity control property of the humidity control building material body is maintained. In the case where the antifouling layer is formed after the thin layer glazing is applied to the surface of the humidity-controlling building material main body, it is possible to more sufficiently prevent or suppress the penetration of the dirt into the humidity-controlling building material body. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail. In the present invention, the object obtained by firing the humidity-controlling building material system is preferably a thin layer glazing on the surface as in Patent Document 3. The body of the humidity-containing building material can be, for example, volcanic pumice layer or diatomaceous earth, acid white clay, activated clay, zeolite, and water in various places called deer marsh, Daze soil and colloidal soil impervious layer and miso soil. In the humidity-controlling materials such as kaolinite, the following blending ratio and chemical composition, and other clays such as clay or vermiculite, terracotta, wax, feldspar, and glass scrap The components and the like are mixed, and extrusion molding or calender molding is carried out, and the obtained molded body is fired and produced. < blending ratio (parts by weight) > Humidity control materials such as deer marsh soil: 100 clay: 1 00 〜1 〇〇〇 vitreous composition: 0 to 500 201235330 The glazed humidity-control building material can be used here The molded body obtained by the above-described method is fired after being glazed, or may be produced by firing a shaped voxel, then glazing, and further firing. In addition, a groove portion (back groove) may be formed on the back surface of the humidity control building material. When the humidity-controlling building material having the groove portion on the back surface is applied to a wall surface or the like, a ventilation path can be secured between the wall surface and the back surface of the humidity-conditioning building material, and the humidity control function can be improved. It is important to maintain the high humidity control performance even if the surface of the building material is glazed. Ideally, the body of the humidity-controlling building material after glazing is desired to have a humidity control performance of more than 80% of the body of the humidity-controlling building material before glazing. In addition, the moisture absorption and desorption performance of the 24-hour cycle of the humidity-control building material body is preferably I50 g/m2 or more. In this way, in order to perform glazing while maintaining high humidity control performance, it is important to control the glazing area or the glazing thickness, and the surface of the body of the humidity control building material is glazed to satisfy the following (i) and (ii). At least one condition is preferred. The glaze can be sprayed, screened, printed, etc., and the method is not limited. The glaze is suitable for the slurry of the ground alkaline aluminum borosilicate glass glass. (i) The glass layer produced by the glaze constitutes the area of the surface of the body of the humidity-conducting building material (hereinafter referred to as the "glazing area ratio" ") is below 90%. (Π) The maximum thickness of the glass layer (hereinafter referred to as Γ maximum thickness) produced by the glaze is 300 μm or less. If the ratio of the above-mentioned glazing area exceeds 90%, the decrease in the humidity control performance significantly impairs the humidity control performance as a humidity-conditioning building material. However, if the glazing area ratio is less than 1 〇% in the case of -9 - 201235330, the glazed surface is too small, and the effect of the decoration and the stain resistance cannot be sufficiently obtained. Therefore, the proportion of the glazing area is preferably set at 10 to 90%, especially 3 to 85%. Further, the ratio of the glazing area can be measured by a wiping test of the ink or the like as described in the following examples. In such a manner, the ratio of the glazing area is set to 90% or less, and the maximum thickness is not particularly limited, but it is desirably set to be 500 μm or less. In addition, when the maximum thickness exceeds 3 ΟΟμιη, the reduction in humidity control performance becomes large when the ratio of the glazing area exceeds 90%, so the maximum thickness is preferably set to 300 μm or less. However, if the maximum thickness is too thin, the effect of improving the decoration and the stain resistance by glazing cannot be sufficiently obtained. The maximum thickness of the glazing area ratio is 95 to 100%, which is preferably 10 to 10 (^111 is preferred, and in the case of 90 to 95%, it is preferably 20 to 20 (^111 is preferred. In such a way that the glass layer is thinned, the high humidity control performance can still be maintained in the case of fully glazing the body of the humidity control building material, and the reason may be that in the case of forming a thin glass layer, the defects of the substrate or The gas generated in the firing process, etc., causes the glass layer to easily pass through the fine pores of the water vapor permeability through the body of the humidity control building. In order to glaze the ratio of the glazing area and/or the maximum thickness, the glazing method is appropriately adjusted, or The amount of glaze used for glazing, or the specific gravity of glaze may be used. For example, when glazing is performed by a spray method or the like, the ratio of glazing area can be suppressed by reducing the amount of glazing per -10-201235330 area. In addition, when the glazing is performed by the showering method or the like, the maximum thickness can be reduced by reducing the amount of glazing per unit area. When performing the glazing, it is necessary to have a corresponding firing. The glass material of the piece, however, when it is rapidly fired by the roller hearth kiln, the glass material can select a substance whose softening point is lower than the firing temperature by 100 to 400 t and has a moderate melt viscosity. If the viscosity is too low, the glass formed by the glazing is buried in the fine pores of the humidity-controlling building material body which exerts the humidity control effect, and the humidity control performance is greatly impaired. Therefore, it is necessary to not impair the humidity control performance. In a way, the amount of glazing and the viscous viscosity of the glaze (the softening point of the glass) are appropriately adjusted. Other methods that can be used are the glazing method, which is not fully glazed and is in the form of spots, lines, and lattices. In the printing method, for example, the glaze adhered to the body of the humidity-controlling building material is kept at a certain interval by the screen, so that the ratio of the glazing area can be reduced. In addition, in the centrifugation method, the glaze is attached when it is attached. Other glazing methods have a larger spot shape, so that the glazing area can be reduced, which is effective for maintaining the humidity control performance, and the pattern can be added by glazing to improve the pattern. The glaze used may be a slurry having a specific gravity of about 1.01 to 1.90 obtained by simply mixing glass and water, and may be used by blending clay or pigment in a stepwise manner. The blending pigment can further enhance the pattern. Further, in the present invention, in order to prevent moisture from diffusing to the main body (for example, the base layer), a water repellent such as a sand latex may be attached to the main body of the humidity control building by means of light coating or spraying. -11 - 201235330 The antifouling layer containing a fluorine-based oil-repellent agent formed on the body of the humidity-controlling building material can be applied to the coating liquid for forming an anti-fouling layer containing a fluorine-based oil-repellent agent. It is formed on the wet building material body and dried. [Fluor-based oil-repellent agent] This gas-based oil-repellent agent is suitable as a polymer having a perfluoroalkyl group in a side chain, and is specifically suitable for WO2008/136436, or WO2008. The following compound is described in /136435: <Compound of WO2008/136436> [1] A water- and oil-repellent composition comprising a copolymer having a basis based on the following monomer (a) The polymerization unit is based on the following monomer (b) The polymerization unit, the ratio of the polymerization unit based on the monomer (b) is the total of the polymerization unit based on the monomer (a) and the polymerization unit based on the monomer (b) (1 〇〇 Mo Among the ear%) accounted for 30% to 80% of the moles.
