[Prior Art] Titanium dioxide is a semiconductor photocatalyst. When it is irradiated with ultraviolet light, it absorbs ultraviolet rays and becomes an excited state. When it is activated to form hydroxyl radicals and adsorbs pollutants such as mold or bacteria floating in the room, it has strong oxidizing power. Decompose organic matter into carbon dioxide and water. At this time, the titanium dioxide of the catalyst does not chemically change, and the photocatalytic reaction can be continued semi-permanently. On the one hand, silver complex compounds are known to have antibacterial, anti-mildew, deodorant, etc., for example, a coating with a silver complex compound is applied to the wall of a hospital ward to help prevent nosocomial infections. Further, the use of a plastic containing a coordination compound to produce a toy for a baby, a ring for a bus or a tram, a stair handrail for a public building, and the like, and a product for a film material having an antibacterial and antifungal effect has also been developed. Titanium dioxide is mixed with a silver coordination compound to exert the functions of the above-mentioned substances and to hold the properties. Therefore, it is used as a coating material for various commercializations, such as deodorization of air purifiers and deodorizing filters, and decontamination of environmental pollutants. SUMMARY OF THE INVENTION -5- (2) 1280143 [Disclosure of the Invention] However, the conventional coating material has the following problems. (1) A non-oxidized, silver-coordinated compound 'is itself a chemically stable substance. Therefore, the mixed molten titanium oxide and the silver complex compound in the solution do not have a chemical or physical bond, and the solution is in a state of being dispersed independently of each other. Therefore, when the solution is not sufficiently stirred, the titanium oxide and the silver complex compound are not uniformly mixed, and only a solution in a state of uneven mixing can be obtained. Further, even if it is sufficiently stirred and uniformly mixed, it is left for a while, and it is in a state of uneven mixing by natural convection of the solution or the like. When the wall surface is coated with such a heterogeneous mixed solution, the antibacterial effect is sparse, and the non-uniformity is not expected in terms of the effect of the effect, and the means for uniformly mixing the titanium oxide and the silver complex compound is developed. . (2) When the environmental pollutants to be decomposed do not come into contact with the titanium dioxide of the catalyst, they will not be activated when irradiated with light and cannot be decomposed. The antibacterial or antifungal action of the silver complex compound, when the environmental pollutants are present at the separation from the silver coordination compound, the environmental pollutants will not be effective, and the antibacterial ability of the silver coordination compound will not be produced. When the titanium dioxide and the silver coordination compound are simply mixed, the substance cannot maintain the function of actively capturing the environmental pollutants, and when the amount of environmental pollutants leaving the titanium oxide and the silver complex compound is large, the decomposition of the environmental pollutants is caused. There is a problem that efficiency cannot be improved. Therefore, the object of the present invention is to provide a coating material which can uniformly mix titanium oxide silver complex compounds, thereby improving the decomposition efficiency of environmental pollutants. -6- (3) 1280143 In order to solve the above problems, the present invention provides a coating material which is characterized by a photocatalyst which is porous with a porous apatite and a molten solution in which a silver thiosulfate complex compound is mixed and melted. Further, in order to solve the above problems, the present invention provides a powder of apatite composite type titanium dioxide and a silver thiosulfate complex compound made of porous apatite-coated titanium dioxide, and an acrylic latex, a latex emulsion, and a surfactant. A coating material characterized by mixing and melting of water into a molten solution. [Effect of the Invention] Thus, the present invention is a combination of a photochemical agent of porous pus stone and a silver sulfate-containing coordination compound, which is mixed and dissolved by a molten solution, and apatite formed by porous apatite-coated titanium dioxide. The composite titanium dioxide powder and the sulfur-silver coordination compound are mixed with the acrylic latex and the lanthanum latex and the surfactant and the molten solution of the water, and the photocatalyst and the silver thiosulfate coordination compound are uniformly mixed. The combination of apatite and physics reflects the uniform mixing state and produces a mixed combination of uniform mixing ratio. Once the combination is not easy to separate, it becomes a stable binding state, and the solution can maintain a certain mixing ratio without stirring. Apatite not only acts as a binder for the combination of photocatalysts and silver sulfate-containing coordination compounds, but also acts as a capture material for capturing the floating bacteria or mold or atmospheric pollutants in the air, and the pollutants are moved to When a photocatalyst or a silver complex compound is decomposed into a harmless heat body, it is absorbed by the heat. That is to say, efficient decomposition can increase the decomposition efficiency of pollutants. 1280143 (4) [Embodiment] [Best Mode for Carrying Out the Invention] Next, an embodiment of the present invention will be described. The wall coating material of the present invention is a composite type titanium dioxide molten solution made of a porous apatite-coated titanium dioxide, a powder of apatite composite type titanium dioxide, an acrylic latex, a latex emulsion, a surfactant, and water. The silver thiosulfate coordination compound is dissolved to become a mixed disperser. Titanium dioxide contained in the apatite composite titanium dioxide solution, which is a porous apatite shoulder made of calcium phosphate, and the titanium dioxide powder of the porous apatite is used to enhance the effect of the photocatalytic titanium dioxide. , leap to improve the efficiency of pollutants. That is, the photocatalyst titanium dioxide acts on the decomposed pollutants, and is decomposed by photochemical oxidative decomposition to decompose the pollutants, which must be in contact with the titanium dioxide crop. The apatite system acts to produce more of this physical contact. Titanium dioxide itself does not retain the property of adsorbing and retaining pollutants, and only decomposes occasionally adsorbed substances. On the one hand, the apatite formed by calcium phosphate maintains the selective adsorption characteristics of the pollutants and does not decompose the pollutants. Therefore, the use of the neighboring limestone of the Oxidation. When the ammonia is negatively apatite, the surface of the fine particles exposed by titanium dioxide forms a vertical convex shape on the surface of the apatite. Due to this convex protrusion structure, the apatite composite type titanium oxide solution is directly coated on the wall surface of the wall, and the exposed portion of the titanium oxide is not in direct contact with the wall material. Therefore, the oxidation effect as a photocatalyst for dioxins is not as good as that of the wall surface, and it is not necessary to necessarily treat the bottom. In this way, the pollutants are adsorbed and maintained by the apatite, and the pollutants are also directly in contact with -8- 1280143 (5) titanium dioxide. In this way, the contaminant titanium dioxide is brought into contact, and as a photocatalyst, titanium dioxide is more effective, and the decomposition and purification efficiency of the pollutants is drastically improved. The acrylic latex and the enamel emulsion contained in the apatite composite type titanium dioxide solution are added for the purpose of improving the adhesion of the final product to the wall material and finally forming the hydrophilicity of the mixture. The adhesion of the acrylic latex is not dripping on the wall surface, and it is close to the wall surface. It is not necessary to carefully adjust the operation of the substrate. The painting step can be simplified. In addition, the mixed solution is used to optimize the decomposition and purification of pollutants, and a surfactant is added to keep the mixture weakly acidic. Apatite composite titanium dioxide solution, which is made of calcium phosphate, is a titanium dioxide micro-powder, a liquid material which is simply melted with acrylic latex, lanthanum latex and surfactant mixed solution, and is apatite composite provided by five major industries. The type of titanium dioxide 20% solution, simply omitting the various solution blending procedures, of course, the raw materials can also be blended. In this case, the method for producing the titanium dioxide powder of the apatite may be produced by the manufacturing method disclosed in JP-A-2002-172332. Further, in order to ensure light transmittance, titanium dioxide is preferably in the form of a fine powder. The silver thiosulfate complex is produced by a method known in the art, that is, silver acetate (CH^COOAg) is dissolved in pure water at 40 ° C to prepare a saturated solution. Sodium sulfite (Na2S04 · 7 Η 2 〇 ) and sodium thiosulfate (N a 2 S 2 0 3 · 5 Η 2 0 ) were sequentially dissolved in this saturated solution to obtain a silver complex compound. The solution containing the silver coordination compound is mixed as a carrier of yttrium (JIS Β type), shouldering a silver coordination compound, and the surface of the carrier is formed by using a sol-9 - 1280143 (6) gel method by si Ο 2 bone clinic The coated film forms an inorganic antibacterial agent of a silver thiosulfate complex. The mixed liquids produced as described above were blended at the following mixing ratios. That is, the apatite powder of the apatite shoulder is in the range of 2 w% to 6 w%, the ratio of the silver thiosulfate complex compound inorganic antibacterial agent is 2 w% to 3 w%, and the latex is about 1 w% of the interface. The active agent was about 2 w%, and the total amount of the mixture was 100%. The temperature of the mixture was maintained at about 35 ° C (± 5 ° C) with a stirrer until the solution had no mixing difference. The standard mixing time to no mixing difference is approximately 20 minutes (± 5 minutes) per 10 liters. The solution thus formed is mixed with a brush to coat the wall surface. Table 1 shows the decomposition efficiency of the contaminant material of the coating material of the present invention when compared with the conventional example. The test method is based on JIS Z 280 1 (film adhesion method). The test used three strains of Staphylococus aureus II D 1677, Escherichia coli IFO 3972, and Pseudomonas aeruginosa IFO 3080. The culture of the culture of the coating material of the present invention is applied to three cultures of the culture of the original membrane material and the culture of the uncoated culture (the blank of the table), and the cultures are planted separately. The strains were compared with the number of bacteria after 2 hours of incubation under UV irradiation, and the relevant three cultures were carried out. The number of implanted bacteria was 1 · 2 χ 1 05 for Staphylococcus, 2.7 X 1 05 for coliform bacteria, and 1.7 x l 〇 for P. aeruginosa. -10- (7) 1280143 Table 1 The present invention is a blank film covering material film material Staphylococcus sterilization rate 9 9.9% 8 3.8% Number of bacteria <10 2·6χ103 1.6xl04 Coliform sterilization rate 9 7.5% 7 8.3 % Number of bacteria 1. 7x104 1 .5x1 05 6.9x1 〇5 Green gallstone sterilization rate 9 9.8% 8 4.7% Number of bacteria 1 · 8χ102 l.lxlO4 7.2x1 Ο4
由試驗結果，塗覆本發明之覆膜材料時之殺菌效果， 即污染物質分解效率，與向來之覆膜材料比較，可知改善 變高。 如上所述，依本發明之覆膜材料，光催化劑之二氧化 鈦微粉末肩負吸附環境污染物質之磷酸鈣所成之磷灰石 時，此粉末溶融生成持有粘著性溶融液之磷灰石複合型二 氧化鈦液。續之，硫代硫酸銀配位化合物添加磷灰石複合 型二氧化鈦液製作混合液。當添加混合之際，混合液強制 攪拌’均勻混合肩負磷灰石之二氧化鈦與硫代硫酸銀配位 化合物。於均勻混合狀態硫代硫酸銀配位化合物吸附肩負 磷灰石。即’二氧化鈦與硫代硫酸銀配位化合物以磷灰石 爲介呈物理的結合。 二氧化鈦與硫代硫酸銀配位化合物，於均勻混合狀態 以磷灰石爲介呈物理的結合。即反映均勻之混合狀態，生 -11 - 1280143 (8) 成均勻混合比之混合結合物。一旦結合時，不容易分離， 安定的呈現結合狀態，溶液不攪拌亦可保持一定的混合 比。一方面，有關磷灰石不存在狀態之向來混合，二氧化 欽與硫代硫酸銀配位化合物，由於不呈物理之結合，溶液 加以攪拌，此等物質之混合狀態，不能保持剛攪拌後之狀 態。以上所述之本發明之均勻混合效果，混合液於塗覆前 可不用攪拌混合液之作業效果，圖謀縮短塗覆作業時間。 磷灰石，不僅結合二氧化鈦與硫代硫酸銀配位化合物 之作用而已，具有捕捉空氣中浮游移動之雜菌或霉或大氣 污染物質之捕捉材料之作用。具有捕捉力，將污染物質挪 近二氧化鈦與硫代硫酸銀配位化合物，分解成爲無害氣體 爲大氣所吸收。即，可產生效率化的分解，產生提高污染 物質分解效率之效果。 〔產業上之利用領域〕 本發明之光催化劑體材料，浮游於室內之雜菌或霉等 之污染物質，不產生有害之副產物，分解成無害化物，可 直接塗覆於壁面。分解必要之能源僅室內燈之日光燈所發 之紫外線即已充分可發揮期望之效果。同時淨化又無污染 破壞環境。因此，作爲環境淨化壁面粉刷材料，於產業上 之利用價値很高。 -12-As a result of the test, the bactericidal effect, that is, the decomposition efficiency of the pollutants, when the coating material of the present invention was applied was found to be higher than that of the conventional coating material. As described above, according to the film material of the present invention, when the titanium oxide fine powder of the photocatalyst is apatite formed by adsorbing calcium phosphate which is an environmental pollutant, the powder is melted to form an apatite composite having an adhesive molten solution. Type titanium dioxide solution. Further, a silver thiosulfate complex compound is added to prepare a mixed solution of the apatite composite titanium oxide liquid. When the mixing is added, the mixture is forcibly stirred to uniformly mix the titanium dioxide and the silver thiosulfate coordination compound. The silver thiosulfate complex is adsorbed to the apatite in a uniformly mixed state. That is, the titanium dioxide and the silver thiosulfate coordination compound are physically combined with apatite. Titanium dioxide and silver thiosulfate coordination compound in a state of uniform mixing with apatite as a physical bond. That is, it reflects a uniform mixing state, and produces -11 - 1280143 (8) into a mixed mixture of uniform mixing ratios. Once combined, it is not easy to separate, and the stability is in a combined state, and the solution can maintain a certain mixing ratio without stirring. On the one hand, the apatite is not mixed with the state of the abundance, the dioxins and the silver thiosulfate coordination compound, because the physical combination is not stirred, the solution is stirred, and the mixed state of the substances cannot be kept just after the stirring. status. According to the uniform mixing effect of the present invention as described above, the mixed liquid can be used without shortening the coating operation time without the effect of stirring the mixed liquid before coating. Apatite is not only combined with the action of titanium dioxide and silver thiosulfate coordination compound, but also has the function of capturing the floating bacteria or mold or atmospheric pollutants in the air. It has a trapping force to move pollutants closer to titanium dioxide and silver thiosulfate coordination compounds, and decomposes them into harmless gases that are absorbed by the atmosphere. That is, efficient decomposition can be produced, and the effect of improving the decomposition efficiency of the pollutants can be produced. [Industrial Applicable Field] The photocatalyst material of the present invention is a pollutant which is floating indoors, such as bacteria or mildew, does not cause harmful by-products, decomposes into a harmless substance, and can be directly applied to a wall surface. The necessary energy is decomposed. Only the ultraviolet light emitted by the fluorescent lamp of the indoor lamp can fully exert the desired effect. At the same time, it is clean and free from pollution and damages the environment. Therefore, as an environmentally cleaned wall flour brush material, the industrial use price is very high. -12-
