[Technical field to which the device belongs]

 The present invention relates to a roof material for construction, and more particularly to a new roof material having excellent physical properties, durability and workability required for the roof material.

[0002]

[Prior art and its problems]

 Conventionally, various sheet roofing materials for construction have been known, such as a fiber cloth coated with a waterproof material, but in recent years, the required characteristics of the roofing material have become more severe. Roofing materials for construction are required to have harsh physical and chemical properties such as water resistance, light resistance, heat resistance, tensile strength, frictional strength, and incidental adaptability to expansion and contraction due to temperature of the building body. In addition, it is required that the installation work be easy and light as a roofing material, and that the price be reasonable as a building material. An object of the present invention is to provide a roofing material that highly satisfies all the above-mentioned required characteristics.

[0003]

[Means for Solving the Problems]

 The roofing material of the present invention has a structure in which a coating layer of silicone rubber is arranged on one surface of a fiber cloth. As the fiber cloth constituting the roofing material of the present invention, woven fabrics, knitted fabrics, and non-woven fabrics of glass fibers, chemical fibers such as polyester fibers, polyamide fibers, and acrylic fibers are preferably used. The surface of this fiber cloth is coated with silicone rubber. As the silicone rubber, commercially available one-component and two-component silicone rubbers can be used. The commercially available flame-retardant silicone rubber is particularly preferable. A roofing material can be obtained by coating and curing silicone rubber, and the sheet layer of the obtained roofing material has a standard thickness of 2 to 3 mm, and can be set to about 5 mm depending on required properties such as strength.

The surface of the roofing material thus obtained is usually flat, and due to the water-repellent property of the silicone rubber, it is slippery in the presence of water. Therefore, when it is used as a roofing material for a building that has the possibility of walking, it is preferable to have an uneven pattern on the surface to prevent slipping. The irregularities are, for example, about 0.2 to 0.5 mm, and the pattern shape may be an appropriate shape such as a continuous shape such as vertical and horizontal cross girders or a discontinuous shape such as dots. The roofing material of the present invention satisfies the above-mentioned required characteristics of the roofing material to a high degree, and as a result of a weather resistance test, it exhibits a durability of 20 years or more in a normal use condition.
