根下地材を、簡易に製造することができる。[Detailed Description of the Invention [0001] The present invention relates to a method of manufacturing a roof base material,
In particular, improved weather resistance, sealing properties of nailed parts, etc.
The roof base material relates to a method of manufacturing a roof base material that can be easily manufactured. 2. Description of the Related Art Conventionally, as a roof base material, for example, there is a material described in Japanese Patent Application Laid-Open No. Hei 8-13716. This roof base material is made of a soft synthetic resin sheath.
The paper is bonded to both the upper and lower surfaces of the base material,
A sheet-like base material of a soft synthetic resin is protruded through the paper on one side of the paper, and the protruding portion is intended to provide a foot sliding effect when performing a tile roofing operation. [0004] However, when the above-mentioned roof base material is nailed and fixed to a field board, it is necessary to use a seam.
Although the base material is made of a soft synthetic resin,
There is a problem that the sealing property of the nailed portion of the sheet-like base material is insufficient, and that the material is a synthetic resin, so that the weather resistance is not sufficient. [0005] The present invention aims at providing a method of manufacturing a roofing base material which is adapted to remove said problems. [0006] [0007] [Means for Solving the Problems] In order to achieve the above purpose
A method for producing a roof bed material of the present invention carries the first layer formed of a paper or nonwoven, co over the first layer to be transported - data - stored in the modified asphalt And cooling the modified asphalt during transportation. After cooling, the modified asphalt is passed between a first roll and a second roll arranged vertically, and The unevenness formed on the surface of the first roll forms the unevenness on the surface of the second layer formed of the modified asphalt. [0008] A method for manufacturing a roof base material of an embodiment of the embodiment of the present invention will be described with reference to the drawings. 1 to 5, reference numeral 1 denotes a roof base material used for a wooden house roof base. The roof base material 1 includes a first layer 2 made of paper or nonwoven fabric and a first layer 2. A second layer 3 provided on the first layer 2 and formed of modified asphalt and having an uneven surface. The first layer 2 and the second layer 3 are joined together. ing. In particular, when the first layer 2 is a non-woven fabric made of, for example, polyethylene, polyester, polypropylene or the like and is combined with the second layer 3 which is a modified asphalt, since both are flexible, Good follow-up to In addition, as a modified asphalt, for example, a material mainly composed of asphalt and rubber, and more specifically, for example, polybutadiene, polyisoprene, styrene butadiene rubber (SBS), attack polypropylene (APP), etc. Synthetic rubber
10 to 15% by weight is blended. The uneven shape of the surface of the second layer 3 is, for example,
As shown in FIG. 4, a cross shape 3a protruding from the surface of the second layer 3 and a shape 3b obtained by cutting a rectangular corner portion are formed into a pattern. As described above, the reason why the surface of the second layer 3 is formed in a concavo-convex shape is that when a person rides on the second layer 3 and performs a roofing operation, the surface of the second layer 3 is formed. In order to avoid danger due to falling by preventing the feet from slipping due to the uneven shape of
The purpose of this is to ensure a drainage function so that rainwater that has entered the layer 3 is not blocked by the roof 4. When the roof base material 1 is nailed and fixed to the base plate 5, the roof base material 1 is made of modified asphalt, and the modified asphalt has flexibility. The sealing performance of the struck portion can be ensured. Furthermore, since the roof base material 1 uses the modified asphalt, the weather resistance is also good. In order to manufacture the above-described roof base material 1, for example, as shown in FIG. 5, one end of a first layer 2 formed of rolled paper or nonwoven fabric is coated with a coater-6. Supply towards. The coater 6 is melted at about 180 ° C. to about 2 ° C.
The modified asphalt at 00 ° C. is stored, and a fixed amount of the modified asphalt is applied onto the first layer 2 via the outlet 6a. 7 is a first roll, 8 is a second roll,
The first roll 7 is arranged above, the second roll 8 is arranged below the first roll 7, and the surface of the second roll 8 arranged below is smooth. However, the surface of the first roll 7 disposed thereon has an uneven shape. Reference numeral 10 denotes a guide roll. Therefore, the first layer 2 made of paper or nonwoven fabric is transported by a transport means such as a motor (not shown), and stored in the coater 6 from above the transported first layer 2. The supplied modified asphalt is supplied. During transportation, the modified asphalt is cooled to about 120 ° C. by natural cooling or the like, and after cooling, it passes between the first roll 7 and the second roll 8 arranged above and below. The surface of the second layer 3 made of the modified asphalt has the uneven shape formed on the surface of the first roll 7 disposed thereon, as shown in FIGS.
An uneven shape as shown in FIG. 4 is formed. [0017] [0018] [Effect of the Invention] According to the manufacturing method of the roof bed material 請 Motomeko 1 wherein, on the first layer by supplying the modified asphalt over the first layer to be transported After the modified asphalt is cooled while being transported, and cooled, the second layer is passed between a first roll and a second roll which are disposed above and below, and Forming an uneven shape on the surface of the second layer formed of the modified asphalt provided on the first layer, with the uneven shape formed on the surface of the arranged first roll; Therefore, a roof base material having good sealing properties and weather resistance at the nailed portion can be easily manufactured.
