Description of the Related Art In the conventional urethane coating film waterproofing method, the parapet part is constructed by applying a urethane coating material having improved thixotropy using a non-woven mat or glass mesh as a reinforcing material, and finally applying a top coat. Finish with. In general, the steps are: 1) apply primer on the base 2) lay a reinforcing material and apply urethane waterproof material 3) 2) after curing step, apply urethane waterproof material 4) topcoat application Target. When applying the urethane waterproof material in the horizontal direction, give the urethane waterproof material self-leveling (a property that naturally flows to create a smooth surface) and spread it with a plaster plaster or a trowel with a comb. Therefore, it is easy to obtain a smooth surface with a uniform thickness only by carefully spreading the prescribed coating amount. On the other hand, in the parapet portion including the vertical surface, if the urethane waterproof material applied to the vertical surface has the self-leveling property described above, it is difficult to obtain a prescribed coating amount due to sagging after the vertical surface coating. A urethane waterproof material that imparts thixotropy (thixotropic property) and is resistant to sagging is used on such a vertical surface. The urethane waterproof material with thixotropy property does not easily cause sagging, but since the traces of the iron during coating work tend to remain, it takes skill to obtain a smooth surface similar to the flat surface, and the construction efficiency is horizontal. Extremely lower than. Furthermore, it is also difficult to apply a uniform thickness to the construction surface. Since the durability of the urethane waterproof material may depend on the thickness, it also requires skill to form a waterproof layer having uniform durability at the construction site.

Since the undercoating material of the present invention has excellent adhesiveness with the urethane waterproof material, it is possible to easily form a waterproof coating film having a uniform thickness on the rising portion and / or the falling portion at the construction site. In addition, since the flexible foam layer is provided on the back surface of the base sheet, even if there are fine irregularities on the surface of the base, it is possible to adapt to the irregularities, and thus the surface is more It can be applied smoothly. The foam of the foam layer of the flexible synthetic resin or synthetic rubber-based foam may be a synthetic resin such as polyethylene, polypropylene, vinyl chloride or urethane, E

５〜３０μが適当である。The surface synthetic resin film has a function as an adhesion medium for firmly adhering and integrating a base sheet and a waterproof film to be applied next, for example, a urethane waterproof film. However, as a property required for the surface synthetic resin film to achieve this purpose, it is of course excellent in adhesiveness with the waterproof film applied to the upper surface, but during the construction of the waterproof sheet. It is important that the water resistance is excellent and the water absorption is small so that there is no problem even if it is exposed to rainfall. Examples of such a film include a film obtained by subjecting a general-purpose synthetic resin film such as polyethylene, polyester, and nylon to corona discharge treatment, an ethylene-vinyl alcohol copolymer resin film, and a polyurethane film. Among them, the ethylene-vinyl alcohol copolymer resin film is a film with good water resistance and good water absorption, excellent in adhesiveness with urethane-based coating waterproofing material without surface treatment, and from the economical aspect. Are also preferred films. However, since the characteristics of the ethylene-vinyl alcohol copolymer resin film change depending on the copolymerization ratio of ethylene and vinyl alcohol, it is preferable to use a film having an appropriate ratio. That is, when the ratio of ethylene is increased, the water resistance is improved and the water absorption is reduced, but the adhesiveness to the urethane-based waterproof coating material is reduced. Further, when the proportion of vinyl alcohol increases, the adhesiveness with the urethane-based coating film waterproof material improves, but the water resistance decreases and water absorption becomes easier. For this reason, the ethylene-vinyl alcohol copolymer resin film has an ethylene copolymerization ratio of about 20% by mol%.
It is preferably 80%, particularly preferably about 30-60.
%belongs to. The thickness of the film is not particularly limited, but is 3 to 70 μ, preferably 5 to 30 μ from the economical point of view.

Further, a synthetic resin film may be laminated between the base sheet and the adhesion-improving surface synthetic resin film to prevent migration of oil from the base sheet. The base sheet and the surface synthetic resin film may be laminated using, for example, an adhesive suitable for both materials, or the surface synthetic resin film may be laminated with another suitable film in advance as an adhesive. In addition, it can be carried out by a commonly used laminating technique such as a method of laminating the base sheet with thermocompression bonding.

Those formed of any mixture of one or more species were used. The support may be a single layer or two or more layers. In the case of multiple layers, the material of each layer may be the same or different. These polymeric materials were kneaded in accordance with a general method so that additives such as a softening agent, a filler, a reinforcing agent, an antiaging agent, etc. were kneaded so as to be uniformly dispersed and molded into a sheet. On the surface of the sheet (whether vulcanized or non-vulcanized), an ethylene-PVA copolymer film or an ethylene-PVA copolymer film having excellent adhesiveness with a urethane waterproof material is further provided with a urethane waterproof material. Acrylic-urethane-based paint coating film is laminated to improve adhesion,
A composite sheet having excellent adhesiveness to the urethane waterproof material was produced by molding with a uniform thickness. A composite sheet was prepared by laminating a closed cell type foam layer having a foaming ratio of 15 to 25 times on the lower surface of the composite sheet. An acrylic pressure-sensitive adhesive layer having excellent weather resistance, water resistance and stain resistance was formed on the lower surface of the foam layer as a pressure-sensitive adhesive layer. 2. A release sheet was attached to the lower surface of the pressure-sensitive adhesive. As such a release sheet, any conventionally known release sheet, for example, 50 to 120 g / m 2 kraft paper with one side
It is possible to laminate a synthetic resin film such as polyethylene having a thickness of 5 to 30 μm, and apply a silicone resin or the like as a release agent on the surface of the film layer. Further, a synthetic resin film having a thickness of about 30 to 100 μm coated with a release agent such as a silicone resin can also be used. 3.

A treatment is performed to ensure that the sheet is not inferior in terms of toughness and toughness. One of such reinforcement treatments is, for example, a treatment of attaching a reinforcement tape so as to cover at least a part of the joint. As the reinforcing tape, for example, the composite sheet may be used in the form of a tape. After the reinforcing tape was attached, waterproofing treatment was performed with a urethane waterproofing material. As the urethane waterproof material, use a two-component rubber type with low viscosity, and apply it in multiple times so that the amount applied at one time is small enough to prevent dripping or iron marks. did. For example, in the case of coating in two times, the coating amount of urethane resin is 1.5 to 2 in both the first layer and the second layer.
It was applied so as to be about 2.0 Kg / m 2 . When applying the urethane waterproof material, an application tool such as a roller capable of forming irregularities on the surface may be used to perform a process such as patterning. Further, when applying the urethane waterproof material, the primer treatment may be performed partially, for example, only on the rising portion such as the vertical surface of the parapet portion. In addition, the type and / or viscosity of the urethane waterproof material used in the rising part and the falling part or the flat part of the building may be changed. For example, the urethane waterproof material used in the rising part may be the falling part or the flat part. It is possible to further prevent the occurrence of sagging by using a material having a higher viscosity than that used in.
