Abstract
Description
本発明は、地面に敷設する防つるシートに関し、特に山を切り開いて建設した道路の両側の法面に敷設するのに適した防つるシートに関するものである。 The present invention relates to a protective sheet to be laid on the ground, and particularly to a protective sheet suitable for being laid on the slopes on both sides of a road constructed by carving out a mountain.
従来より、地面から雑草等の植物が生育するのを抑制するため、地面に防草シートを敷設することが行われている。かかる防草シートとして、表面側から、短繊維不織布よりなる保水層、アスファルトよりなる遮光層及び長繊維不織布よりなる補強層の順で積層一体化してなるものが知られている（特許文献１、請求項１）。そして、アスファルトよりなる遮光層に植物忌避剤を含有させることも提案されている（特許文献１、段落００４３）。 Conventionally, a weed-proof sheet has been laid on the ground in order to suppress the growth of plants such as weeds from the ground. As such a weed-proof sheet, one is known in which a water-retaining layer made of a short-fiber non-woven fabric, a light-shielding layer made of asphalt, and a reinforcing layer made of a long-fiber non-woven fabric are laminated and integrated in this order from the surface side (Patent Document 1, Patent Document 1, Claim 1). It has also been proposed to include a plant repellent in a light-shielding layer made of asphalt (Patent Document 1, paragraph 0043).
かかる防草シートは、地面から雑草が生育するのを防止しうるものの、地面に沿って茎を伸ばすつる植物の生育を抑制することが困難であった。すなわち、防草シートが敷設されていない箇所で生育したつる植物が、地面に沿って防草シート表面まで茎を伸ばし、防草シートをつる植物が覆ってしまうということがあった。なぜなら、防草シート表面が短繊維不織布よりなり保水層で構成されており、植物忌避剤が存在しないからである。 Although such a weed-proof sheet can prevent weeds from growing from the ground, it is difficult to suppress the growth of vines that grow stems along the ground. That is, a vine that grew in a place where the weed control sheet was not laid extended its stem along the ground to the surface of the weed control sheet, and the vine plant covered the weed control sheet. This is because the surface of the weed-proof sheet is made of a short-fiber non-woven fabric and is composed of a water-retaining layer, and there is no plant repellent.
このため、短繊維不織布よりなる保水層にも、植物忌避剤を塗布又は含浸させることも考えられる。しかしながら、短繊維不織布に植物忌避剤を塗布又は含浸させても、雨水によって植物忌避剤が流出し、防草シート表面においてつる植物の茎が伸びるのを長期に亙って防止することができなかった。 Therefore, it is also conceivable to apply or impregnate the water-retaining layer made of the short fiber non-woven fabric with a plant repellent. However, even if the short fiber non-woven fabric is coated or impregnated with the plant repellent, it is not possible to prevent the plant repellent from flowing out due to rainwater and the vine stems from growing on the surface of the weed control sheet for a long period of time. rice field.
本発明の課題は、防草シート表面において、つる植物の茎が伸びるのを長期に亙って防止することにある。 An object of the present invention is to prevent the stems of vines from growing on the surface of a weed-proof sheet for a long period of time.
すなわち、本発明は、表面側から、孔につる忌避剤が付着している複数の多孔質石からなる多孔質石層、つる忌避剤が含まれてなるアスファルト層及びポリエステル不織布層の順で積層一体化されてなる防つるシートに関するものである。 That is, in the present invention, from the surface side, a porous stone layer composed of a plurality of porous stones having a vine repellent attached to the pores, an asphalt layer containing the vine repellent, and a polyester non-woven fabric layer are laminated in this order. It relates to an integrated anti-judicial sheet.
本発明に係る防つるシートは、その表面側が多孔質石層よりなる。多孔質石層は、複数の多孔質石からなり、その質量が３００〜７００ｇ／ｍ2程度である。そして、多孔質石の孔には、つる忌避剤が付着している。多孔質石としては、微細な孔の開いた石であれば任意のものが採用しうるが、特に軽石を用いるのが好ましい。多孔質石の粒径は、２〜６４ｍｍ程度であるのが好ましい。つる忌避剤としては、従来公知のものが用いられるが、特にクロロトリルオキシプロピオン酸ポリグリコールエステルを用いるのが好ましい。 The surface side of the protective sheet according to the present invention is made of a porous stone layer. The porous stone layer is composed of a plurality of porous stones and has a mass of about 300 to 700 g / m 2. A vine repellent is attached to the pores of the porous stone. As the porous stone, any stone having fine pores can be used, but pumice stone is particularly preferable. The particle size of the porous stone is preferably about 2 to 64 mm. As the vine repellent, conventionally known ones are used, but it is particularly preferable to use chlorotriloxypropionic acid polyglycol ester.
多孔質石の孔につる忌避剤を付着させるには、つる忌避剤を含む粘着剤又は接着剤を多孔質石に塗布すればよい。粘着剤又は接着剤としては、従来公知のものを用いることができ、特にアクリル系樹脂を用いるのが好ましい。つる忌避剤の付着量は任意であるが、多孔質石の質量に対して、１〜５質量％であるのが好ましい。 In order to attach the vine repellent to the pores of the porous stone, a pressure-sensitive adhesive or an adhesive containing the vine repellent may be applied to the porous stone. As the pressure-sensitive adhesive or the adhesive, conventionally known ones can be used, and it is particularly preferable to use an acrylic resin. The amount of the vine repellent attached is arbitrary, but is preferably 1 to 5% by mass with respect to the mass of the porous stone.
多孔質石層の裏面側には、つる忌避剤が含まれてなるアスファルト層が積層されている。アスファルト層の質量は７００〜２０００ｇ／ｍ2程度である。つる忌避剤としては、従来公知のものが用いられ、特にクロロトリルオキシプロピオン酸ポリグリコールエステルを用いるのが好ましい。つる忌避剤の含有量は任意であるが、アスファルトの質量に対して、０．１〜１．０質量％であるのが好ましい。アスファルトとしては、従来公知の石油アスファルト又は天然アスファルトを用いることができるが、特に改質アスファルトを用いるのが好ましい。改質アスファルトは多孔質石等との付着性に優れており、多孔質石層とアスファルト層及びアスファルト層とポリエステル不織布層との一体化が強固になるからである。また、改質アスファルトは耐候性に優れているからである。アスファルト層は、ポリエステル不織布に含浸されているのが好ましい。すなわち、アスファルト層は、ポリエステル不織布の内部及び裏面まで浸入しているのが好ましい。これにより、敷設した防つるシートの下面からの雑草等の生育を防止することができる。 An asphalt layer containing a vine repellent is laminated on the back surface side of the porous stone layer. The mass of the asphalt layer is about 700 to 2000 g / m 2. As the vine repellent, conventionally known ones are used, and it is particularly preferable to use chlorotriloxypropionic acid polyglycol ester. The content of the vine repellent is arbitrary, but is preferably 0.1 to 1.0% by mass with respect to the mass of asphalt. As the asphalt, conventionally known petroleum asphalt or natural asphalt can be used, but it is particularly preferable to use modified asphalt. This is because the modified asphalt has excellent adhesion to porous stones and the like, and the integration between the porous stone layer and the asphalt layer and the asphalt layer and the polyester non-woven fabric layer is strengthened. Moreover, the modified asphalt has excellent weather resistance. The asphalt layer is preferably impregnated with a polyester non-woven fabric. That is, it is preferable that the asphalt layer penetrates to the inside and the back surface of the polyester non-woven fabric. This makes it possible to prevent the growth of weeds and the like from the lower surface of the laid anti-vine sheet.
アスファルト層と一体化されているポリエステル不織布層としては、従来公知のものを用いうるが、ポリエステル長繊維で構成されたスパンボンド不織布を用いるのが好ましい。ポリエステル長繊維は耐候性に優れており、また、引張強度等の機械的強度が高いからである。ポリエステル不織布層の目付は５０〜３００ｇ／ｍ2程度である。 As the polyester non-woven fabric layer integrated with the asphalt layer, conventionally known ones can be used, but it is preferable to use a spunbonded non-woven fabric composed of polyester filaments. This is because polyester filaments have excellent weather resistance and also have high mechanical strength such as tensile strength. The basis weight of the polyester non-woven fabric layer is about 50 to 300 g / m 2.
ポリエステル不織布層の裏面には粘着剤が塗布されているのが好ましい。粘着剤が塗布されていると、防つるシートを地面に敷設する際にずれにくくなり、作業性が向上する。また、粘着剤面には、合成樹脂製フィルムや離型紙等の離型シートを貼着しておくのが好ましい。防つるシートを運搬する際に、べたつきにくくなり、取扱性が向上する。粘着剤及び離型シートが備えた防つるシートは、離型シートを取り除き、粘着剤面を地面に当接しながら、敷設することになる。 It is preferable that an adhesive is applied to the back surface of the polyester non-woven fabric layer. When the adhesive is applied, it is difficult for the protective sheet to slip when laid on the ground, and workability is improved. Further, it is preferable to attach a release sheet such as a synthetic resin film or a release paper to the pressure-sensitive adhesive surface. When transporting a vine-proof sheet, it becomes less sticky and easier to handle. The release sheet provided with the adhesive and the release sheet is laid while removing the release sheet and bringing the adhesive surface into contact with the ground.
本発明に係る防つるシートは、以下の如き製造方法で得ることができる。まず、粘着剤液又は接着剤液につる忌避剤を溶解又は分散させた溶液を、多孔質石に塗布して、その孔につる忌避剤が付着した多孔質石が複数準備する。一方、アスファルトにつる忌避剤を含有せしめた忌避剤含有アスファルトを準備する。また、ポリエステル不織布を準備する。そして、忌避剤含有アスファルトを加熱混合して流動状態とし、ポリエステル不織布表面に塗布すると共に、流動状態となっている忌避剤含有アスファルトの上に複数の多孔質石を載置する。以上の方法で、本発明に係る防つるシートを得ることができる。なお、ポリエステル不織布の裏面に粘着剤を塗布し、さらに粘着剤面に離型シートを貼着してもよいことが前述したとおりである。 The protective sheet according to the present invention can be obtained by the following manufacturing method. First, a pressure-sensitive adhesive solution or a solution in which a vine repellent is dissolved or dispersed in an adhesive solution is applied to a porous stone to prepare a plurality of porous stones to which the vine repellent is attached to the pores. On the other hand, a repellent-containing asphalt containing a vine repellent is prepared. Also, prepare a polyester non-woven fabric. Then, the repellent-containing asphalt is heated and mixed to make it in a fluid state, and it is applied to the surface of the polyester non-woven fabric, and a plurality of porous stones are placed on the repellent-containing asphalt in the fluid state. By the above method, a protective sheet according to the present invention can be obtained. As described above, the adhesive may be applied to the back surface of the polyester non-woven fabric, and the release sheet may be further attached to the adhesive surface.
本発明に係る防つるシートは、つる植物の茎が伸びる恐れのある地面に敷設する。たとえば、山を切り開いて建設した道路は、法面からつる植物の茎が伸び、道路に侵入することがある。したがって、この法面に防つるシートを敷設しておけば、道路につる植物の茎が侵入するのを防止することがてきる。 The anti-vine sheet according to the present invention is laid on the ground where the stems of vines may grow. For example, a road constructed by carving out a mountain may have vine stalks extending from the slope and invading the road. Therefore, if a protective sheet is laid on this slope, it is possible to prevent the stems of vines from invading the road.
本発明に係る防つるシートは、その表面に、孔につる忌避剤を付着せしめた多孔質石が複数存在している。すなわち、つる忌避剤が孔に付着しているため、雨水等によって、つる忌避剤が流出しにくくなっている。したがって、防つるシートの表面に、つる植物の茎が伸びるのを、長期に亙って防止しうるという効果を奏する。 The anti-seizure sheet according to the present invention has a plurality of porous stones having a vine repellent attached to the pores on the surface thereof. That is, since the vine repellent is attached to the pores, it is difficult for the vine repellent to flow out due to rainwater or the like. Therefore, it has the effect of preventing the stems of vines from growing on the surface of the vine sheet for a long period of time.
