The present invention relates to a durable mold-proofing method for general buildings, and particularly to a durable mold-proofing method that has excellent adhesion and mold-proofing properties for bathroom tile joints, plastic boards, etc. In recent years, mold damage to buildings has increased significantly, and it has come to have a serious impact on daily life. This is due to the diversity of building materials, and the use of materials that are prone to mold in ancillary work such as painting work, cloth pasting work, fiber wall coating work, etc., and recently, lifestyles have changed as well, and heating This is thought to be due to the widespread use of indoor spaces, which has led to a change in the way people warm indoors during the winter. As is well known, the favorable conditions for mold growth are (1) appropriate temperature (20~30℃), (2) appropriate humidity (70~30℃), and (2) appropriate humidity (70~30℃).
(80%), (3) abundant nutrition, and (4) provision of appropriate oxygen, etc., but there are also some substances in the paint used in the above-mentioned painting work, as well as in the adhesive used in cloth pasting work, regarding fiber wall construction. This is thought to be because the adhesive resin, paper, cloth, etc. contain a lot of nutrients, and the temperature environment has become favorable for mold growth even during the winter, when growth was previously suppressed. However, mold damage in buildings is of course not limited to areas rich in nutrients; as mentioned above, the temperature and humidity are favorable, and on top of that, there are bathrooms with poor air circulation, especially in tile joint areas. There are many cases of mold growth and its control is a problem. Regarding the control of these molds, mold and bacteria can easily grow in oil-based paints, lacquer paints, silicone resin paints, polyurethane resin paints, epoxy resin paints, and emulsion paints that have traditionally been used for the interior and exterior of houses. Since it has become clear that these paints contain various anti-mold agents, coating tests have been attempted, but currently there are almost no anti-mold products that guarantee long-term anti-mold effects in buildings. The reality is that it doesn't exist. The present inventor has learned from many years of experience that the coating film of conventional paints formed by painting is only superficial and superficial, that the coating film is easy to peel off, and that many spots are formed during painting. Since such peeling areas or spots become breeding grounds for mold or bacteria and gradually spread the disaster, it is impossible to achieve a mold prevention effect. If this solution is mixed with a penetrating waterproofing agent made by dissolving a waterproofing component in a petroleum-based solvent and applied to the surface of the material to be treated by spraying or painting, the antifungal solution will become a part of the material to be treated. The waterproofing agent also penetrates from the surface along the capillary wall to the inner surface, and after the solvent evaporates, a gel layer is formed by a chemical reaction on the penetration part and the surface, blocking the air phase with a strong waterproof film. However, we have now discovered that this provides a durable anti-mold effect. Next, the type of anti-mold agent, the penetrating waterproofing agent, the diluting solvent, the mixing ratio thereof, etc. used in the durable anti-mold method of the present invention will be explained. The antifungal agent or fungicide used in the antifungal method of the present invention has low toxicity, is non-irritating, has no harmful effects on the skin or eyes, and has a strong antifungal growth prevention effect. The first condition for selection was that it should have an anti-corrosion effect. It was also confirmed that when added to the penetrating waterproofing agent, which is an essential component of the present invention, it is stable and compatible, has a long-lasting effect, and has the property of not being decomposed by light or heat. A disinfectant that satisfies these conditions is shown and explained below. 1 Antifungal agent used in the present invention (1) 2-(4-thiazolyl)-benzimidazole Abbreviation: thiabendazole, or TBZ
It is a pale yellow powder with the following chemical structure: As can be seen, it is an extremely low toxicity substance that does not contain metal or chlorine in its molecule. Chemically stable and difficult to hydrolyze, it does not decompose even at 300℃. Acute toxicity LD 50 3600
mg/Kg (mouse). Comprehensive test results including chronic toxicity, dermal toxicity, and irritation to the skin and eyes have been clarified through 10 years of data, and it has been evaluated as an extremely safe disinfectant. It is said to be effective in inhibiting the growth of mold on paints and similar materials at low concentrations of 0.2 to 25 ppm. (2) N-dimethyl-N'-phenyl-N'-(fluoro-dichloromethylthio)-sulfamide It has the chemical structure, and its abbreviation is Prebentol A4. It has low toxicity among similar fungicides, does not stain paint films, and is suitable for addition to solvent-based paints. It has sterilizing properties against a wide range of mold, bacteria, and yeast, making it suitable for indoor painting. 2 Penetrating waterproofing agents and diluents To carry out the durable mold prevention method of the present invention, one or more of the currently used effective mold prevention agents are dissolved in an organic solvent that is a suitable diluent. The solution is applied to the material to be treated by coating or spraying, and suitable solvents are organic solvents that generally exhibit greater solubility and permeability than water, particularly hydrophobic solvents. Therefore, toluene is used in this method, but benzene and other aromatic solvents can of course also be used. Particularly suitable for this method is the use of Lutzker thinner containing 60 to 70% Tolhole in it. The Lutzker thinner used herein dissolves the above-mentioned fungicide used in the present invention and can be made into a solution of at least 0.5%. In the present invention, a solution of at least 0.5% Lutzker thinner of the above-mentioned fungicide is applied to the material to be treated to deeply penetrate the material, and at the same time, a penetrating waterproofing agent diluted with Lutzker thinner is added to the Lutzker thinner of the above-mentioned fungicide. By applying the solution together with the solution, that is, by mixing it, a film formed by the waterproofing agent that penetrated at the same time as the fungicidal agent that penetrated is formed inside the treated material, which improves the mildewproofing durability of ordinary paints. This makes it possible to obtain an anti-mold method that has significantly better durability. The penetrating waterproofing agent described here consists of several types of waterproofing resins, mainly consisting of a petroleum-based solvent or a mixed solvent of paraffin and aromatics, and a non-silicon water-repellent resin. When applied to objects such as mortar, blocks, bricks, unglazed tiles, and plastics,
It penetrates deeply into the inner surface, and after the solvent evaporates, a gel layer is formed by a chemical reaction along the capillary wall and surface of the treated object, giving it a strong waterproof effect with excellent weather resistance and stain resistance. An example of this is the product name "Chemistop" by Mitsui Petrochemical Industries, Ltd. The quality standards are as shown in the table below.

認められぬもの[Table] Lutzker thinner as a diluent used in this method is compatible with the petroleum solvent of the penetrating waterproofing agent used herein and can be mixed in any proportion. In order to obtain an excellent durable effect with the durable mold prevention method of the present invention, it is necessary to dilute the penetrating waterproofing agent with the above mold prevention agent in Lutzker thinner and use it as a complete solvent. Generally speaking, the degree of dilution should be based on the degree of density or density of the material to be mold-proofed, or the degree of absorption.
Generally, a highly diluted agent is well absorbed into the object to be treated, adheres closely to the agent, and becomes difficult to peel off. This is equivalent to the effect of a primer (undercoat) used in adhesives, and by diluting Ratsuker thinner to about 10 times the volume of the penetrating waterproofing agent + mold prevention agent and applying it. It adheres well to the surface of plastic materials and does not peel off. The excellent adhesiveness of the antifungal treatment solution of the present invention is one of the features of the present invention. In addition, when a dilution of 3 times the volume is applied to the surface of wood, the naturalness of the wood is maintained.
It becomes difficult to determine the presence or absence of paint through visual inspection. For plastic materials, if the dilution is less than 2 times, there is a risk of peeling or elution. Here, the standards for the material to be treated and the degree of dilution (capacity) are as follows: When the material to be treated is brick or stone slab, the degree of dilution is 1:1 (permeable waterproofing agent + antifungal agent: Lutzker thinner) (capacity). ) is sufficient, and if the material to be treated is concrete or ricin material, the dilution degree is similarly 1:2 (volume), and if the material to be treated is plastic, wood, wall material, cloth material, the dilution degree is 1: :
Effective dilutions range from 3 to 1:10. When applying the durable mold prevention method of the present invention, it is of course possible to inspect mold damage that has already occurred.
Even if autopsy is not possible, it is necessary to perform primary sterilization by spraying with hypochlorous acid solution and secondary sterilization with alcohol or benzalkonium chloride in advance. Next, examples of the present invention will be shown. Example 1 For the purpose of comparing the conventional method and the method of the present invention for a bathroom including concrete parts and others finished with ricin material, anti-mold treatment was performed using the standard method of the present invention, while the same anti-mold agent was applied. The mold growth status was determined by applying a conventional paint containing the same concentration and using the same surface treatment amount, leaving it for a certain period of time after painting, and comparatively inspecting the coated surface. In both methods, a preliminary sterilization process has already been completed before construction. A. Construction method 1. Preparation of anti-mold solution (1) According to the present invention As an anti-mold agent, 20 g of TBZ and 20 g of Preventol A4 were weighed out, and a penetrating waterproofing agent ["Chemistop" manufactured by Mitsui Petrochemical Industries, Ltd.] was added to this. Add 1000ml and mix, then add about 4000ml of Ratsker thinner (approximately 3480
g) and stir well to remove the anti-mold agent (approximately 0.94 g).
% solution, total volume of about 5000 ml (about 4520 g) was prepared. (2) Using conventional paint Weigh out 20g of TBZ and 20g of Preventol A4 as anti-mold agents, add 1000ml of PVC resin paint and mix, then add about 4000ml (approx. 3480g) of Lutzker thinner,
Stir well to remove the total amount of 0.94% fungicide solution.
4550g was prepared. 2. Painting method: Apply an average of approximately 66.6 ml (approximately 57.9 g) per square meter to the bathroom walls finished with ricin.
Painting was carried out using the anti-mold liquid according to the present invention and the anti-mold liquid according to the conventional method. B. Results of painting Table 1 shows the results of a comparative autopsy of the mold that had formed on the treated material two years after the painted surface was left as it was, based on the following criteria. Standards for autopsy The six-step method is indicated by the following symbols. Symbol : Mold status: - No mold growth - - Where hyphae can be barely detected with a microscope - - Where hyphae can be seen with the naked eye + - Where the amount of hyphae is somewhat large ++ - Where the amount of hyphae is even greater ++++ The amount of mycelia is extremely large, and the antifungal effect is not recognized.

Regarding the construction of each building, we compared the method conventionally used by a mold prevention company in this area with the method of the present invention (shown in Example 1) according to the autopsy standards explained in Example 1. This is an example in which the occurrence of mold was determined one year and two years after construction. The following are examples of conventional construction methods that are commonly practiced here. Mainly for cases where mold has already grown in bathrooms, etc., the steps are shown in numerical order: 1. Oxidation and bleaching with a 5-6% solution of hypochlorous acid. 2 Sterilization with ethanol or benzalkonium chloride. 3. Painting with paint containing anti-mold agent. The method of the present invention is based on the method of Example 1. The construction site is a bathroom, but it is also made of wood,
Table 2 shows the occurrence of mold in the joints of ricin-finished concrete, tile joints, Izu stone, plastic ceilings, and unit baths.

のよりはるかに劣る結果が得られている。[Table] From the test results of Example 1, a difference of approximately 2 to 3 stages was observed between the application results of the method of the present invention and the application results of the anti-mold paint containing the same amount of the same anti-mold agent, and there was a difference between the two. It is determined that there is clearly a significant difference. From the results of Example 2, it was found that the difference between the two was even more significant. The content of antifungal agents in conventional antifungal paints has not been published, but based on solubility, it is approximately 0.5 to 1%.
It is estimated that the mold is within the range of 100,000,000,000,000,000,000,000,000,000,000. The reality is that the effects are only guaranteed for about 6 months. For 1 kg of paint conventionally used by the inventor,
A 5% mold inhibitor containing 30 g of TBZ and 20 g of Prebentol A4 at a weight ratio of paint: mold inhibitor = 1000:50 is also used as mold inhibitor 1 according to the preparation method shown in Example 1 invented this time. % content ratio was obtained.
