Description

本発明は、港湾の防波堤、建物や地下駐車場の出入口などに設置される防水壁材に関するものである。   The present invention relates to a waterproof wall material installed at a breakwater in a harbor, a building or an entrance / exit of an underground parking lot.

高潮や異常降雨などによる海水や雨水の流入を防ぐための防水壁材としては、従来、鉄、ステンレスなどの金属材料からなるものや、コンクリート、セメント、モルタルなどの無機質材料からなるものが使用されている(例えば特許文献1参照)。   Conventionally, waterproof wall materials to prevent the inflow of seawater and rainwater due to storm surges and abnormal rainfall have been made of metal materials such as iron and stainless steel and those made of inorganic materials such as concrete, cement and mortar. (See, for example, Patent Document 1).

特開昭53−91929号公報JP-A-53-91929

従来の防水壁材は、平常時に設置場所の景観を損ない易いという問題がある。そこで、本発明の目的は、海水や雨水の流入を防ぐとともに、平常時は設置場所の景観を損ない難い防水壁材を提供することにある。   The conventional waterproof wall material has a problem that it is easy to damage the scenery of the installation place in normal times. Accordingly, an object of the present invention is to provide a waterproof wall material that prevents inflow of seawater and rainwater and that does not easily damage the scenery of the installation location during normal times.

本発明者は、防水壁材として透明樹脂板を用いることにより、上記目的を達成できることを見出し、本発明を完成するに至った。すなわち、本発明は、透明樹脂板からなることを特徴とする防水壁材を提供するものである。   The present inventor has found that the above object can be achieved by using a transparent resin plate as the waterproof wall material, and has completed the present invention. That is, the present invention provides a waterproof wall material comprising a transparent resin plate.

本発明によれば、海水や雨水の流入を防ぐとともに、平常時は設置場所の景観を損ない難い防水壁材を得ることができる。   ADVANTAGE OF THE INVENTION According to this invention, while preventing inflow of seawater or rainwater, the waterproof wall material which cannot easily impair the scenery of an installation place at normal time can be obtained.

以下に本発明を詳細に説明する。本発明の防水壁材は、透明樹脂板からなるものである。透明樹脂板としては、例えば、ポリスチレン樹脂、ポリ塩化ビニル樹脂、アクリロニトリル−スチレン共重合樹脂、メタクリル酸メチル−スチレン共重合樹脂、アクリロニトリル−ブタジエン−スチレン共重合樹脂、ポリカーボネート樹脂、アクリル樹脂などの各種熱可塑性樹脂の板が好ましく用いられる。中でも、透明性や耐候性の点から、アクリル樹脂板が好ましく用いられる。   The present invention is described in detail below. The waterproof wall material of the present invention is made of a transparent resin plate. Examples of the transparent resin plate include various heats such as polystyrene resin, polyvinyl chloride resin, acrylonitrile-styrene copolymer resin, methyl methacrylate-styrene copolymer resin, acrylonitrile-butadiene-styrene copolymer resin, polycarbonate resin, and acrylic resin. A plastic resin plate is preferably used. Among these, an acrylic resin plate is preferably used from the viewpoint of transparency and weather resistance.

アクリル樹脂は、メタクリル酸メチルの単独重合体であってもよいし、メタクリル酸メチルとこれ以外の単量体との共重合体であってもよく、共重合体である場合、その単量体に占めるメタクリル酸メチルの割合は、50重量%以上、好ましくは70重量%以上、より好ましくは90重量%以上であるのがよい。また、共重合体である場合、メタクリル酸メチル以外の単量体としては、アクリル酸アルキルやスチレンが好ましく用いられる。   The acrylic resin may be a homopolymer of methyl methacrylate, or may be a copolymer of methyl methacrylate and another monomer, and if it is a copolymer, the monomer The proportion of methyl methacrylate in the water content is 50% by weight or more, preferably 70% by weight or more, more preferably 90% by weight or more. In the case of a copolymer, alkyl acrylate or styrene is preferably used as a monomer other than methyl methacrylate.

透明樹脂板の厚みは、通常1〜600mm程度である。厚肉のものは、積層接着により得てもよく、この場合、積層接着が容易な点から、アクリル樹脂版が好ましく用いられる。また、透明樹脂板の全光線透過率は、無色透明のものであれば80%以上、スモーク色などの着色透明のものであれば20%以上であるのが好ましい。   The thickness of the transparent resin plate is usually about 1 to 600 mm. Thick ones may be obtained by lamination adhesion. In this case, an acrylic resin plate is preferably used from the viewpoint of easy lamination adhesion. The total light transmittance of the transparent resin plate is preferably 80% or more if it is colorless and transparent, and 20% or more if it is colored and transparent such as smoked color.

透明樹脂には、一般に用いられる添加剤を添加してもよい。添加剤としては、例えば、紫外線吸収剤、酸化防止剤、可塑剤、着色剤などが挙げられる。   A commonly used additive may be added to the transparent resin. Examples of the additive include an ultraviolet absorber, an antioxidant, a plasticizer, and a colorant.

紫外線吸収剤としては、例えば、ベンゾフェノン系化合物〔チバ・スペシャルティ・ケミカルズ(株)の“チヌビンP”、住友化学(株)の“スミソーブ340”など〕、ベンゾフェノン系化合物〔シプロ化成(株)の“シーソーブ110”、住友化学(株)の“スミソーブ110”など〕、ヒンダードアミン系化合物〔チバ・スペシャルティ・ケミカルズ(株)の“チヌビン770”〕などが挙げられる。   Examples of the ultraviolet absorber include benzophenone compounds (such as “Tinubin P” from Ciba Specialty Chemicals Co., Ltd., “Sumisorb 340” from Sumitomo Chemical Co., Ltd.), and benzophenone compounds (“Cipro Kasei Co., Ltd.”). Seasorb 110 "," Sumisorb 110 "from Sumitomo Chemical Co., Ltd.], hindered amine compounds [" Tinubin 770 "from Ciba Specialty Chemicals Co., Ltd.] and the like.

酸化防止剤としては、例えば、フェノール系化合物〔住友化学(株)の“スミライザーBP101”、“スミライザーGM”など〕、リン系化合物〔(株)アデカの“マークPEP−8”、“マークPEP−24”など〕などが挙げられる。   Antioxidants include, for example, phenolic compounds (such as “SUMILIZER BP101” and “SUMILIZER GM” from Sumitomo Chemical Co., Ltd.), phosphorus compounds (“MARK PEP-8” and “MARK PEP- 24 ″ etc.].

可塑剤としては、例えば、ジブチルフタレート、ジオクチルフタレートのような芳香族多価カルボン酸エステル、ジオクチルアジペート、アセチルトリブチルシトレートのような脂肪族多価カルボン酸エステルなどが挙げられる。   Examples of the plasticizer include aromatic polyvalent carboxylic acid esters such as dibutyl phthalate and dioctyl phthalate, and aliphatic polyvalent carboxylic acid esters such as dioctyl adipate and acetyltributyl citrate.

着色剤としては、例えば、アントラキノン系染料〔住友化学(株)の“スミプラストGreenG”、“スミプラストBlueOR”など〕、ペリノン系染料〔住友化学(株)の“スミプラストOrangeHRP”など〕などが挙げられる。   Examples of the colorant include anthraquinone dyes (such as “Sumiplast Green G” and “Sumiplast BlueOR” from Sumitomo Chemical Co., Ltd.) and perinone dyes (such as “Sumiplast Orange HRP” from Sumitomo Chemical Co., Ltd.).

透明樹脂板には、その表面を硬くし、傷が付き難くするとともに、耐溶剤性を向上させる目的で架橋樹脂層を被覆することができる。   The transparent resin plate can be coated with a crosslinked resin layer for the purpose of making the surface hard and making it difficult to be scratched and improving the solvent resistance.

架橋樹脂層の組成や被覆方法については特に限定されないが、例えば、分子内に2つ以上のアクリロイル基又はメタクリロイル基を有する架橋性化合物を含む塗料〔広栄化学工業(株)のコーエイハードM101など〕を、透明樹脂板の表面に浸漬、噴霧、塗布などの方法により付着させた後、これに紫外線や電子線などの活性エネルギー線を照射することによって架橋硬化させて被覆する方法や、シリコン系やメラミン系の架橋性化合物を含む塗料を、透明樹脂板の表面に浸漬、噴霧、塗布などの方法により付着させた後、これを加熱することによって架橋硬化させて被覆する方法が好ましい。架橋樹脂層は、厚さが通常0.1〜10μmとなるように透明樹脂板の表面に被覆される。その厚さがあまり小さいと、耐擦傷性が低下する場合があり、またあまり厚いと、剥離が起こり易いなど、耐久性に問題が生じる場合がある。   The composition of the cross-linked resin layer and the coating method are not particularly limited. For example, a paint containing a cross-linkable compound having two or more acryloyl groups or methacryloyl groups in the molecule (Koei Chemical Co., Ltd., Koeihard M101, etc.) Is applied to the surface of the transparent resin plate by dipping, spraying, coating, or the like, and then is applied by crosslinking and curing by irradiating active energy rays such as ultraviolet rays or electron beams. A method in which a coating material containing a melamine-based crosslinkable compound is attached to the surface of the transparent resin plate by a method such as dipping, spraying, or coating, followed by heating to crosslink and cure to coat is preferable. The crosslinked resin layer is coated on the surface of the transparent resin plate so that the thickness is usually 0.1 to 10 μm. If the thickness is too small, the scratch resistance may decrease, and if it is too thick, there may be a problem in durability, such as easy peeling.

また、透明樹脂板には、表面の汚れを防止する目的で、例えば、フッ素系樹脂、シリコーン系樹脂、アクリル系樹脂、無機コロイドゾルなどによる被覆層を形成してもよい。   Further, for the purpose of preventing surface contamination, a coating layer made of, for example, a fluorine resin, a silicone resin, an acrylic resin, or an inorganic colloid sol may be formed on the transparent resin plate.

以上説明した透明樹脂板からなる防水壁材を、単独又は支持枠内に施工することで、透明性のある防水壁が得られる。支持枠は、通常、鉄、アルミニウム、ステンレスのような金属材料からなる桟、支柱、固定枠などの構造材から構成される。   A waterproof wall with transparency can be obtained by constructing the waterproof wall material made of the transparent resin plate described above alone or in the support frame. The support frame is usually composed of a structural material such as a cross, a column, and a fixed frame made of a metal material such as iron, aluminum, and stainless steel.

防水壁材の施工方法については特に限定されないが、例えば、防水壁材の周辺を金属製の枠で固定し、コンクリート製基礎壁などに立てられた支柱に取付ける方法や、防水壁材料を金属製の周辺固定枠なしに直接支柱に取付ける方法ないしコンクリート製防水壁に埋め込む方法などがある。   The construction method of the waterproof wall material is not particularly limited. For example, the periphery of the waterproof wall material is fixed with a metal frame, and the waterproof wall material is attached to a column standing on a concrete foundation wall or the waterproof wall material is made of metal. There are a method of attaching directly to a column without a fixed frame of the surroundings or a method of embedding in a concrete waterproof wall.
