Description
【発明の詳細な説明】 〔発明の背景と目的〕 本発明は耐衝撃性防水シートに関するものである。[Detailed description of the invention] [Background and purpose of the invention] The present invention relates to an impact-resistant waterproof sheet.
防水シートはコンクリートビルディングの屋根防水材、
美観池の防水材、廃棄物貯留場の廃液漏れ防止材などに
用いられている。Tarpaulin sheets are roof waterproofing materials for concrete buildings,
It is used as a waterproof material for Bikan Ponds and as a material to prevent waste liquid from leaking at waste storage sites.
廃棄物貯留場は産業廃棄物や家庭の不燃ゴミなどを投棄
するだめ、廃液が土壌中へ漏れ々いことが不可欠である
。Waste storage sites are used to dump industrial waste and household non-combustible garbage, so it is essential that waste liquid leaks into the soil.
廃棄物貯留旭川防水シートは耐水性、耐薬品性が優れて
いるため、廃液による防水シートの侵食劣化は心配ない
。廃棄物貯留場の廃液漏れで最も問題となるのは、防水

まうという欠点があった。即ち、従来の防水シートは廃
棄物と接触する表面が防水シートそのものであり、極め
て破損し易い構造のためである。Asahikawa Waterproof Sheet for Waste Storage has excellent water resistance and chemical resistance, so there is no need to worry about erosion and deterioration of the waterproof sheet due to waste liquid. The most problematic type of waste liquid leakage from waste storage sites is caused by mechanical damage to the waterproof sheet. In general, waste has various shapes and physical properties, and these are dumped with impact due to dumping force, etc. Conventional tarpaulin sheets have the disadvantage of being damaged when hard, heavy, and sharply angled solid waste is dumped by a dump truck. That is, in conventional waterproof sheets, the surface that comes into contact with waste is the waterproof sheet itself, and the structure is extremely fragile.
本発明はかかる点に立って為されたものであって、その
目的とするところは、耐衝撃性に優れた耐衝撃性防水ソ
ートを提供することにある。The present invention has been made based on this point, and its object is to provide an impact-resistant waterproof sort with excellent impact resistance.
本発明の要旨とするところは、防水シート上に接着剤を
介して前記防水シート厚さの１．２倍以上の厚さの緩衝
層を張り合わせ、該緩衝層の上層に前記防水シート厚さ
の０．８倍以上の厚さの保護層を設けて成ることを特徴
とする耐衝撃性防水ソートにある。The gist of the present invention is that a buffer layer having a thickness of 1.2 times or more the thickness of the waterproof sheet is pasted on the waterproof sheet via an adhesive, and the upper layer of the buffer layer has a thickness that is equal to or greater than the thickness of the waterproof sheet. The impact-resistant and waterproof sort is characterized by having a protective layer with a thickness of 0.8 times or more.

Further, the thickness of the waterproof sheet is usually 0.5 to 3.5 mm, preferably 1.0 to 2.0 mm.
本発明において緩衝層の材料は耐衝撃緩和性が優れたも
のならよく、例えばフェルト、不織布。In the present invention, the material of the buffer layer may be any material having excellent impact relaxation resistance, such as felt or nonwoven fabric.

いだめである。Floating fabrics, foam plastics, foam rubber, cotton, acrylic wire, etc. In addition, in the present invention, the reason why the thickness of the buffer layer is set to be 1.2 times or more than the thickness of the waterproof sheet is that if the thickness of the buffer layer is 1.2 times or less, the effect of improving impact resistance will not be exhibited significantly. .
本発明において用いられる保護層材料は、耐衝撃性が優

厚さを防水シートの厚さの０８倍以上としたのは、０．
８倍以下の厚さでは耐衝撃性の向上効果が顕著に発揮で
きないためである。These include resin mortar, enamel, ceramic, unsaturated polyester cured products, and resin cement. In addition, the thickness of the protective layer is 0.8 times or more the thickness of the waterproof sheet.
This is because if the thickness is 8 times or less, the effect of improving impact resistance cannot be significantly exhibited.

である。The impact-resistant tarpaulin sheet of the present invention cannot exhibit excellent impact resistance with a buffer layer or a protective layer alone, but in combination with a buffer layer that is 1.2 times or more and a protective layer that is 0.8 times or more that of the waterproof sheet. It can exhibit excellent impact resistance when
