Field of the Invention The present invention relates to a roofing material such as a tile, a slate, or a metal, which can be laid completely on a surface of a field board in order to ensure waterproofness of the roof. The present invention relates to a layered roofing material.

える。2. Description of the Related Art Since the above-mentioned underlaying material with a self-adhesive layer is entirely adhered to the surface of the baseboard by the self-adhesive layer, a normal roofing underlaying material (such as asphalt roofing) is nailed to the basement sheet. Even if water leaks from a part of the roof, the roofing material and the base plate are in close contact with each other through the self-adhesion layer, so the leaked water does not spread, and almost no water leakage accidents occur. It can be said that it is the ultimate roofing material that can be completely avoided.

“腰”が強く取り扱い易いという利点があった。Conventionally, there are roughly two types of underlaying materials with a self-adhesive layer. One was made of a synthetic resin nonwoven fabric (100 to 200 g / m 2) impregnated with asphalt, and the other was made of base paper impregnated with asphalt. The former using a synthetic resin non-woven fabric as a core material has an advantage that it has a high "tear strength" but a high tear strength, though it has a weak "stiffness". In addition, the latter, which uses asphalt base paper as the core material, is originally paper and lacks tear strength,
There was an advantage that "waist" was strong and easy to handle.

There were many troubles that the self-adhesion layers adhered to each other, and it was extremely difficult to peel off the self-adhesion layers adhered to each other later, resulting in poor workability.

In some cases, small pieces were melted to form pinholes, and the pinholes could not be completely closed by forming an overlaid asphalt layer, which caused a water leakage accident.

A mineral powder layer is formed on the front side of the layer, and a self-adhesive layer is formed on the back side,
It is characterized in that a release sheet is temporarily attached to the surface of the self-adhesive layer, and while asphalt base paper is used as a core material, a pinhole in the core material can be completely closed and tear strength can be increased. Configured.

FIG. 1 is an enlarged sectional view of the roof underlaying material of the present application. The roof underlaying material 1 of the present application has asphalt layers 3 and 3 laminated (including coating) on both sides of a base paper 2 impregnated with asphalt. At least one of the asphalt layers 3 is a composite layer with the nonwoven fabric layer 4.

されている。The roof underlaying material 1 of the present application is a base paper 2 in which a core material is impregnated with asphalt. Since the material is basically “paper”, it lacks tear strength, but has a strong “stiffness”. Excellent handling. However, as for the weak point of the tear strength, the asphalt layers 3 and 3 laminated on both sides of the base paper 2 are used.
Is improved because at least one of them (or both of them) is a composite layer with the nonwoven fabric layer 4 having high tear strength.

It may use waste paper that is a natural environment-friendly material. There is no problem even if plastic fine pieces or small pieces are cut into such waste paper and melted by the heat of asphalt impregnation to form pinholes. The reason is that base paper 2
This is because at least one of the asphalt layers 3, 3 laminated on both sides of the nonwoven fabric layer is a composite layer with the nonwoven fabric layer 4, so that the asphalt blocks the pinholes while being anchored to the nonwoven fabric 4.

する。The mineral powder layer 5 spread on the surface side of the asphalt layers 3, 3 is made of silica sand or other mineral powder, and is mainly used to prevent the tackiness of the asphalt layer 3 and to apply roofing materials. This is to improve the slipperiness at the time. It is also effective for preventing blocking during storage. A paint (indicated by a broken line) 8 may be applied to the surface of the mineral powder layer 5 in order to prevent the mineral powder from falling off and to improve the commercial value. When the paint 8 is made white, the inking effect is also improved.

完璧に塞ぐことができるという効果を奏する。As described above, according to the present invention, at least one of the asphalt layers laminated on both sides of the base paper impregnated with asphalt is made into a composite layer with a nonwoven fabric layer, and the surface side of the asphalt layer is made of mineral. Since the powder layer is characterized by forming a self-adhesive layer on the back side and temporarily attaching a release sheet to the surface of the self-adhesive layer, the base paper impregnated with asphalt as a core material happens to be Even if plastic strips and small pieces were made from waste paper into which the plastic strips and small pieces were laid, even if the plastic strips and small pieces were melted by heat during asphalt impregnation to form pinholes, they were laminated on both sides of the base paper. Since at least one of the asphalt layers is a composite layer with the nonwoven fabric layer, an effect that the pinhole can be completely closed can be obtained.

う効果を奏する。The base paper impregnated with asphalt as a core material is a "paper" which is said to have a low tear strength, but at least one of the asphalt layers laminated on both sides thereof is a composite layer with a nonwoven fabric layer. Therefore, there is an effect that a point having a low tear strength is reliably improved by the action of the nonwoven fabric layer.
