悪くする欠点があつた。 Typical conventional waterproof sheets for exposure are asphalt roofing materials, which are rubberized asphalt sheets with single fibers or fabrics such as glass fibers or polyester fibers interposed as reinforcement materials, or the surface of sheets with such a structure. Roofing materials with sand are known, in which mineral powder is dispersed. However, because this type of roofing material has low elongation, it cannot follow the expansion and contraction of the base when it is pasted onto a fireproof base, so if the base develops cracks or fissures, the roofing material may also crack or break. This caused the phenomenon of zero span tension, and the disseminated mineral powder was gradually removed over time, resulting in the drain being clogged with the mineral powder, making drainage difficult.

る。 The purpose of this invention is to improve the above-mentioned drawbacks and provide a waterproof sheet for exposure that has sufficient resistance even when the movement of the base is large and can be used for a long time as an exposure waterproof. This waterproof sheet for exposure has a structure in which a synthetic polymer roofing material is laminated on one side of a rubberized asphalt layer via a resin film, and an asphalt-impregnated nonwoven fabric is laminated on the other side, and the rubberized asphalt layer The synthetic polymer roofing material laminated in layers is weather resistant and has sufficient functionality for exposure, and due to the presence of the resin film, it does not swell due to asphalt. On the other hand, in the laminated part of the rubberized asphalt layer and the asphalt-impregnated nonwoven fabric, if the cracks in the base become large and cannot be followed, then only the asphalt-impregnated nonwoven fabric, which is the least stretchable, is damaged, and then the rubberized asphalt layer is applied. The synthetic polymer roofing material, which is laminated with layers and resin films, conforms to cracks in the base and provides an exposed waterproofing function.
以下、本考案の露出用防水シートを添付図面に
もとづいて詳細に説明する。 Hereinafter, the exposure waterproof sheet of the present invention will be described in detail based on the accompanying drawings.

The exposed waterproof sheet 1 has a rubberized asphalt layer 2 as the central layer, with a synthetic polymer roofing material 4 laminated on one side via a resin film 3, and an asphalt-impregnated nonwoven fabric 5 laminated on the other side.

きる。 The rubberized asphalt layer 2 constituting the waterproof sheet 1 is basically a bituminous material such as straight asphalt, blown asphalt, or asphalt for waterproofing work, and a rubber component such as ethylene propylene terpolymer, butyl rubber, styrene-butadiene rubber, natural rubber, or heat. It is a mixture sheet made by mixing thermoplastic rubber such as plastic styrene-butadiene copolymer, and the mixing ratio is usually 100% by weight of rubber in order to satisfy adhesion, flexibility, temperature sensitivity, etc. 100-200% by weight of asphalt
If asphalt is less than 100% by weight, the adhesion to the resin film and asphalt-impregnated nonwoven fabric will be poor;
If the amount is larger, the flexibility will be reduced and the temperature-sensitive properties will be inferior. However, of course, a softener, a plasticizer, and an inorganic filler may be appropriately mixed in addition to the above-mentioned additives.

After that, three layers of a rubberized asphalt layer, a resin film, and a synthetic polymer roofing material are used to conform to the base material and provide waterproof function. Furthermore, this asphalt-impregnated nonwoven fabric provides stiffness to the entire exposed waterproof sheet 1, and thus has excellent workability when applied to the asphalt pouring method.

を有している。 As described above, the exposed waterproof sheet 1 of the present invention has a rubberized asphalt layer 2 as an intermediate layer, and a weather-resistant synthetic polymer roofing material 4 is laminated on one side with a resin film 3 interposed therebetween. Therefore, it is weather resistant and fully exhibits its function as an exposed material, and due to the presence of the resin film 3, the synthetic polymer roofing material 4 does not swell, and the asphalt impregnated on the other side. The non-woven fabric 5 is the layer that is the most difficult to stretch, so if the waterproof sheet can no longer follow the cracks in the base, only this layer will break, preventing the entire exposure waterproof sheet from being damaged and maintaining its waterproof properties. This has the effect of imparting stiffness to the waterproof sheet 1 for use and improving the workability of the sheet 1.
