この考案は、建物の屋上等の防水下地材に関す

It is well known that a synthetic resin foam sheet is used as a waterproof base material. As a synthetic resin foam sheet used for this purpose,
Utility Model Publication No. 57-30116 describes the use of a perforated polyethylene foam heat insulating board.

間に導いて密に接着させようとするものである。 This perforated polyethylene foam insulation board is made by laminating a woven or non-woven fabric on one side of a polyethylene foam. The purpose is to introduce the foam insulation board between the foam insulation board and the substrate and bond it tightly.

ある。
Regarding the perforated polyethylene foam insulation board,
Experiments showed that it was difficult to guide the hot asphalt uniformly through the holes between the base and the foam insulation board.
Furthermore, if it flows over the entire surface, there is no place for gas such as water vapor generated from the underlying surface to escape, and the resulting pressure causes it to swell, making it impossible to adhere as expected. Furthermore, this polyethylene foam has poor adhesion to a waterproofing material such as hot asphalt, and therefore has the disadvantage that the exposed waterproofing layer formed thereon is likely to peel off.
この考案は上記の欠点を解決しようとするもの
である。 This invention attempts to solve the above-mentioned drawbacks.

The waterproof base material of this invention has a thin groove that communicates from the edge to each through hole on the surface of the foam sheet that is attached to the base material, which has a large number of through holes formed therein, and at least a through hole in this surface. It is characterized in that a temporary adhesion layer is formed around the hole, and a layer compatible with the waterproof coating material is formed on the other side.

Refers to things with a thin coating.

In this invention, since a temporary adhesive layer is provided at least around the through holes on the adhesive surface of the foamed sheet having through holes to the base, at least the adhesive layer is provided around the through holes, so that when the sheet is placed on the base to be applied, at least The area around the hole is temporarily bonded to the base layer with a temporary bonding layer. Since a groove is formed on the surface that communicates from the edge to each through hole, when a waterproof material such as urethane resin is poured onto the top surface to form a waterproof layer, gas such as air in the through hole can be removed. The water escapes through the narrow grooves, and the waterproof layer flows smoothly into the through holes and reaches the base. Therefore, the sheet is fixed to the base material in a state where the waterproof material is blocked by the temporarily attached portion around the through hole and does not flow between the base material and the base material.

い。 In addition, the water vapor gas generated from the base material then escapes from the narrow grooves, but mainly through the gap between the base material and the base material, which has become separated due to the pressure of the gas. does not occur.
この考案の防水下地材の実施例を図面を参照し
ながら説明する。
An embodiment of the waterproof base material of this invention will be described with reference to the drawings.
１は独立気泡の柔軟性発泡シートであり、貫通
孔１１が100cm2当たり30〜3000個の範囲でほぼ等
間隔に例えば千鳥状に穿孔されている。 Reference numeral 1 denotes a closed-cell flexible foam sheet, in which through-holes 11 are perforated at approximately equal intervals in the range of 30 to 3000 per 100 cm 2 , for example in a staggered pattern.
独立気泡で柔軟性のある発泡シート１は、ポリ

ロピレン等のモノマーと他のモノマーとの共重合
体等の樹脂を主材料とする発泡シートが用いら
れ、特にポリオレフイン系樹脂の架橋発泡体が好
適に用いられる。 The closed-cell, flexible foam sheet 1 is a foam sheet whose main material is a resin such as polyethylene, polypropylene, or a copolymer of a monomer such as ethylene or propylene with another monomer, and in particular, a polyolefin resin. A cross-linked foam is preferably used.
孔の大きさは特に１〜15mmの径の範囲のものが
用いられる。孔径が大き過ぎたり、孔密度が大き
過ぎると発泡シートの強度やクツシヨン性が低下
し、また、孔径及び孔密度が小さいと貫通孔をと
おして下地に接着する効果が小さくいずれの場合
も好ましくない。 The hole size used is particularly in the range of 1 to 15 mm in diameter. If the pore diameter is too large or the pore density is too large, the strength and cushioning properties of the foam sheet will decrease, and if the pore diameter and pore density are small, the effect of adhesion to the substrate through the through holes will be small, which is undesirable in either case. .
なお、発泡シート１の上面には寒冷紗２を貫通
孔１１を阻害しないように貼着されている。これ
は上面に塗膜形成するウレタン防水材５等の防水
材との密着性向上のためである。 Note that cheesecloth 2 is attached to the upper surface of the foam sheet 1 so as not to obstruct the through holes 11. This is to improve adhesion to a waterproof material such as the urethane waterproof material 5 formed on the top surface.

仮着層を形成する。 Then, the depth and width of the side edge of the sheet 1 to be adhered to the base are 0.5 to communicate with each through hole 11.
A narrow groove 12 of about 3 mm is provided, and a temporary adhesive layer 3 is further formed except for the groove and the through hole. This narrow groove 12 is smaller than the through hole 11 and has a size that prevents the paint film waterproofing material from flowing, and the temporary adhesion layer 3 is for temporarily adhering the sheet 1 to the base, and is designed to prevent temporary adhesion. Adhesives and pressure-sensitive adhesives are used. For example, natural rubber-based, chloroprene-based, nitrile-based, or acrylic-based adhesives or pressure-sensitive adhesives may be applied in smaller amounts than those normally used for adhesion or adhesion, such as the usual 100 g/ m2 . If there is, a temporary adhesion layer is formed with a coating amount of 50 g/m 2 , which is approximately half of that.
仮着層３は、この実施例では貫通孔１１及び溝
１２部分を除く全面に形成されているが、貫通孔
２の周囲部分にのみ形成されていてもよい。 In this embodiment, the temporary adhesion layer 3 is formed over the entire surface except for the through hole 11 and the groove 12, but it may be formed only around the through hole 2.
なお、必要に応じて仮着層３を保護し、使用に
際しては剥がされる離型紙を仮着層３面にもうけ

is fixed to the base 4.

The waterproof base material of this invention has thin grooves that lead to the through holes and a temporary adhesive layer on the surface of the perforated foam sheet that is attached to the base material, so that at least the area around the through holes is temporarily adhered when it is laid on the base material. At the same time as the urethane waterproof material formed on the top surface is applied, it flows smoothly into the through hole and reaches the base, but it is blocked by the temporary adhesive area around the through hole and does not flow between the base material and the base. In this state, the sheet is fixed to the base. The temporarily bonded surface formed by the temporary bond layer is then easily peeled off by the pressure of gas such as water vapor generated from the base, and the gas between the layers dissipates to the surroundings through the gaps or the narrow grooves, so that no blistering occurs.
また、発泡シートの上面には、織布もしくは不

性も優れている。 Furthermore, since the foam sheet has a woven or nonwoven fabric on its upper surface, it has excellent adhesion to the waterproof coating material.
