Abstract

(57) [Summary] [Purpose] To provide a durable and easy-to-use construction material that can permanently prevent mold and pests without spraying harmful chemicals. [Construction] A felt-like breathable sheet which has sufficient breathability and does not spill out particulate matters is packed with silica gel or a similar granular humidity conditioner in a sandwich form to form a building base material.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is widely used as a base material for underfloor, walls, ceilings, etc. in general buildings such as houses.

[0002]

[Prior art]

 Moisture and water in building materials such as tatami mats and carpets cause a hotbed of mites and other harmful insects and molds, which significantly impairs habitability. Some methods have also been tried, or methods using hygroscopic sheets as building materials have been tried.

[0003]

[Problems to be solved by the device]

 When such conventional means such as insect repellents are used, they are generally harmful chemicals and are not desirable for the human body, building materials, furniture, etc. However, there was a problem that the effect was not permanent or the effect was not permanent. Further, none of the desiccant or the conventional sheet-shaped building materials using the desiccant can increase the moisture absorption amount so much that the saturated water content is reached at the same time. There was also a problem that it became a useless long item. The present invention aims to solve such problems.

[0004]

[Means for Solving the Problems]

 A granular humidity control material such as silica gel (2) is housed inside a breathable sheet such as a sheet-like felt (1) that has sufficient breathability and does not let out any particulate matter. As a whole, a thick sheet-like construction base material (3) is used.

As a material to be used, the sheet-like felt (1) and the silica gel (2) are typical as described above, but other breathable sheets and granular humidity controlling agents having the same action and effect are obtained. You may replace with wood.

[0006] However, the term "humidity adjusting agent" as used herein means that, like silica gel, it absorbs moisture at high humidity, but releases it at low humidity and returns to its original state. It means that it can be repeatedly reproduced.

The silica gel (2) is mainly in the form of granules having a particle size of about 1 mm, and is distributed as uniformly as possible in the sheet-like felt (1) in a sandwich shape, with about 500 g per 1 m ² as a guide. House as you would.

[0008] As shown in the drawing, the method is to develop a layer of the Shitaka gel (2) between two sheet-like felts (1), and apply this by a known means (fusion) or sewing. It may be integrated into one sheet.

Of course, other breathable sheets that can be similarly processed, such as non-woven fabric, net, and other paper cloth, may be used. In that case, the particle size, amount of use, distribution state and the like of the granular material such as silica gel are appropriately selected in consideration of the thickness, porosity, physical properties, application and the like of the sheet.

[0010]

[Action]

When the granular silica gel (2) is stored in the sheet-like felt (1) as in the present invention, a considerably large amount of the humidity control material of 500 g or more per 1 m ² is extremely speedily and uniformly applied to the floor material, wall material, and ceiling material. Since it absorbs and releases moisture repeatedly depending on the humidity, it is necessary to prevent excess moisture inside the building material that causes mold and pests for a long period of time. Become. At the same time, it was found that it prevents damage to building materials and furniture and also helps deodorize.

[0011]

Example 1 Silica gel (2) having a particle diameter of about 1 mm was sprinkled at about 500 g / m ^{2 on the} entire upper surface of a long sheet-like felt (1) having a thickness of 4.5 mm and a width of about 1 m, and then separated from above. The same long sheet-like felt (1) is piled up, and the two are integrated by fusion bonding to obtain a building base material (3) for a floor having a thickness of about 10 mm.

[0012]

Example 2 The same silica gel was put between two 3 mm-thick non-woven fabrics at a rate of 300 g / m ² and integrated as in the above example. One or more of these are stacked to form a base material for walls or ceilings.

Of course, the present invention is not limited to such examples.

[0014]

[Effect of device]

 As described above, according to the present invention, it is possible to arrange a large amount of humidity control material over a wide area of a building extremely rapidly and uniformly using a sheet material having a relatively low cost and good workability. Therefore, it is possible to permanently prevent the occurrence of high-humidity places that become hotbeds for molds and pests, so that habitability and durability of building materials, etc. can be maintained without spraying harmful chemicals. There is an effect that is very useful for improving.
