Abstract

(57) [Summary] (Modified) [Purpose] Special processing is applied to the surface of the slate roof so that water droplets (condensation) on the attic of the slate roof do not occur. [Structure] The surface of the slate roof 9 is washed, and a water-repellent waterproof material is applied over the two layers 6 and 7 to completely block the air permeability and moisture permeability of the front and back of the slate.

Description

[Detailed description of the device]

 The present invention is intended to prevent the formation of water droplets in the dew condensation state that occur inside the slate roof.

[Industrial applications]

 The present invention relates to a building improvement work and a method for manufacturing a roof building material.

[Prior art]

 In the past, to prevent condensation in buildings, water vapor generated inside the building was absorbed by the walls and ceiling to wait for natural evaporation, and then repeatedly to prevent water droplets from forming on the walls and ceiling. . Therefore, apply a coating film of a material that easily absorbs water vapor to the ceiling plate or the surface of the wall, or apply wallpaper or cloth cloth of the same material to absorb it and allow it to absorb the water vapor naturally. While doing so, it prevented the generation of water drops and the drop. Such a dew condensation preventive coating material is also applied to the inside of the wall material that does not have moisture permeability and the ceiling plate, and if it hardens and adheres, it has the effect of preventing dew condensation. When it is applied to cement wall material, which is extremely heavy, and slate roofs that are exposed to long rain and snow, it does not block the inside and outside of the building, and it always has moisture permeability. It had been. In addition, based on the prior art search report (report number 269), a search was conducted on three applications that are considered to be similar to this proposal, and the following results were obtained. (1) Published Utility Model-56-153517 This proposal is one in which the corrugated sheet of asbestos slate used as a wall material for building is filled with mortar so that the corrugated sheet becomes a flat plate, and the wall is coated. The main purpose is to improve the strength of the material, and it is possible to prevent dew condensation, but it does not prevent water permeability and moisture permeability from the outside at all, and because it has air permeability inside and outside the building, The thickness of the mortar layer does not work as a humidity control layer (it absorbs moisture when the inside of the building is humid and releases moisture when the building is in low humidity, and balances naturally). Although the entire concave surface of the corrugated sheet is filled with mortar cement, 90% of the whole is made up of cement. The mortar has a heavy weight and is structurally unusable, so it has been put to practical use as a roofing material. Absent. (2) Published Practical Use -57-21644 Originally, the purpose was to prevent white slate on the surface of the slate, and in order to prevent the white slate on the slate, the only way to prevent the white slate on the slate is to prevent the white slate from forming. It is not sufficient to apply, and the entire slate must be penetrated to a thickness of 6.3 m / m from the front to the back so that the entire slate is "dubsuke". In this way, the white slate will stop, but conversely, there will be no slate's hygroscopic and moisture-releasing layers, and it will only function as a waterproof plate. In other words, since the humidity control layer disappears, the humidity control function (when the inside of the building is humid, it absorbs moisture, when it is light, it releases moisture and balances naturally) does not work. Therefore, the permeation method of waterproofing agent has very little effect of preventing dew condensation. (3) Regarding Open Practical Use -61-185809 This proposal is for various kinds of prevention of dew condensation on the factory building. As a construction method procedure for corrugated slate roof, (1) All bolts protruding to the roof surface are removed by cutting. (2) Physically and chemically clean (only high pressure water washing). (3) Apply latex mortar. (4) Apply a water-based adhesive. (5) Apply foam synthetic resin. (6) Attach a rubber sheet. (7) Apply thermal barrier paint. As mentioned above, the process is repeated 7 times, which is extremely dangerous for work on a roof with a dangerous asbestos slate. If this amount of work is required, the construction cost will be enormous. Today, I don't hear any practical use. (Note) The process of this proposal in this application is 1, high pressure water washing 2, application of cationic acrylic resin emulsion 3, application of epoxy-modified polyurethane resin coating, and three steps.

[Issues to be solved by the device]

 Slate roofs are used as legal non-combustible building materials in warehouses, iron industry, fisheries, food processing plywood factories, and all other factories. It goes without saying that there are many industries in this area that do not like the formation of condensation and the drop of water drops. Most companies do work to prevent condensation on the inner surface of walls, ceilings, or slate roofs, but in the end, even if a portion of the slate roof is coated with a condensation prevention material thicker than usual, it will not succeed. Eventually, dew condensation occurred on the inner surface of the slate roof, causing water droplets to fall, which bothered operators.

[Means for solving the problem]

 In order to achieve the above object, in the present invention, a method of implementing a means for impeding the moisture permeability of a slate roof has been considered. That is, as shown in FIG. 1, the part where dew condensation usually occurs is the part with dots, and the water droplet of 5 directly adheres to the inside of the slate roof. Especially when the temperature is cold, the temperature difference between the inside and outside becomes severe, so the anti-condensation agent is completely ineffective. The same applies when there is long rain or snow. Therefore, as shown in FIG. 2, the surface of the slate roof is first washed and then the cationic acrylic resin emulsion is uniformly applied. Next, the epoxy-modified polyurethane resin paint is applied evenly. With these two types of water-repellent waterproof resin coatings, it is possible to completely impede moisture permeability, water permeability and breathability. As a result, the slate itself takes on the role of the absorber even in the above-mentioned weather and acts as a dew condensation preventing layer. Therefore, a moisture-absorbing layer with a slate thickness of 6.3 m / m is created without applying dew condensation prevention coating to the inside of the slate roof, and a moisture absorber with a thickness 3 times the coating thickness of the dew condensation preventing agent is 2 m / m. Also, since it is shielded from the outside, it is possible to sufficiently prevent the formation of condensation (water droplets) only by treating the steam inside.

[Action]

 The slate whose surface is waterproof has a regulating action of inhaling or releasing moisture, inhaling moisture when the humidity is high, releasing moisture when the humidity is low, and adjusting the humidity inside the building. Therefore, it is not necessary to apply the anti-condensation agent to the attic of the slate because the slate acts as an anti-condensation agent.

【Example】

 As shown in FIG. 4, 0.7 kg of the cationic acrylic resin emulsion of 6 per square meter is applied to the surface of the slate of FIG. 3, and after drying and curing, the epoxy-modified polyurethane resin coating of 7 is further applied per square meter of 0. Top coat 0.35 kg. It is not necessary to apply anti-condensation agent inside the wall.

[Effects of the Invention] Since the present invention is configured as described above, the occurrence of dew condensation on the implemented building has been eliminated.
