Abstract

<P>PROBLEM TO BE SOLVED: To provide self-cleaning road incidental equipment which can simplify a step associated with the formation of a covering layer, while developing self-cleanability over a long period of time, and which has the covering layer formed without a hindrance, even if a surface of the self-cleaning road incidental equipment has low solvent resistance. <P>SOLUTION: In the covering layer 2, photocatalytic particulates are contained in a coating composition which contains a hydroxyl group-containing fluororesin composition, an isocyanate-based curing agent, a fluorochemical surfactant, an ultraviolet absorber and an organosilicate compound. This enables the covering layer to maintain adhesion and high transparency even if it is exposed outdoors for a long period of time. Since the covering layer can be formed on the outer surface of the road incidental equipment by employing a one-coat one-bake method, the step associated with the formation of the covering layer can be simplified. Since the surface of the road incidental equipment is hardly affected by a solvent even if the covering layer is formed on the outer surface of the road incidental equipment 1 with low solvent resistance, the covering layer can be formed on the outer surface without any hindrance. Additionally, since high hydrophilicity is developed by the mixed photocatalytic particulate, high antifouling performance can be exerted. <P>COPYRIGHT: (C)2008,JPO&INPIT

本発明に係わる最良の実施の形態について、図面に基づき以下に具体的に説明する。 For the preferred embodiment of according to the present invention will be specifically described below based on the drawings.

図1は、本発明に係わる自浄性道路付帯設備の、第一の実施形態を示すもので、(a)は全体を示す斜視図、(b)は外面の詳細を示す縦断面図である。 Figure 1 is a self-cleaning road associated equipment according to the present invention, it shows a first embodiment, a perspective view, (b) is a longitudinal sectional view showing the details of the outer surface showing the whole (a). まず(a)において、道路付帯設備は道路標識柱1Aであり、道路標識柱1Aは、地表面に固着されるベース部1A2と、ベース部1A2から上方に突設されるポール部1A1とから形成されており、ポール部1A1の上方には上下三段に亘って反射シート1A3が巻回されている。 First, in (a), the road associated equipment are road signs pillar 1A, road sign posts 1A is formed from a base portion 1A2 which is secured to the ground surface, the pole portion 1A1 Metropolitan which is projecting from the base portion 1A2 upward are reflective sheet 1A3 over the upper and lower three stages is wound on the upper pole portion 1A1. ポール部1A1及びベース部1A2は、ポリウレタン系樹脂から形成されており、ポール部1A1は車両の衝突等により曲がり且つ復元できるものである。 Pole portions 1A1 and the base portion 1A2 is formed from a polyurethane-based resin, the pole portion 1A1 are those capable and restore bending due to the collision of the vehicle. かかる道路標識柱1Aは、一般にポール部1A1は橙色や緑色の鮮やかな色調となされて昼間における誘目性が高められ、且つ反射シート1A3により、車両の前照灯等が照射された際に再帰反射が起こり、夜間における視認性が高められるものであるが、道路標識柱1Aは一般に道路の側縁に沿って設けられるものであり、自動車の排気ガス等に由来する煤塵や道路周辺の塵埃等の汚染物質が付着し、上述の誘目性や視認性が損なわれる恐れがあるものである。 Such road signs pillar 1A is generally pole portion 1A1 is conspicuity property is enhanced in the daytime is made with orange and green bright color, by and reflective sheet 1A3, retroreflective when headlamp of the vehicle is irradiated occurs, but in which visibility at night is improved, road sign posts 1A is generally one that is provided along the side edges of the road, such as dust, soot and dust and roads around from the exhaust gas of an automobile contaminants adhered, in which there is a possibility that attractiveness and visibility above is impaired.

(b)において、ポール部1A1の外面には、2液熱硬化型ウレタン変性アクリル系のプライマー層3Aが形成され、更にプライマー層3Aの外面に、水酸基含有フッ素樹脂組成物及びイソシアネート系硬化剤を含有するコーティング組成物に、樹脂固形分100重量部当たり、フッ素系界面活性剤0.01〜1.0重量部、紫外線吸収剤1〜15重量部、オルガノシリケート化合物1〜30重量部、及び光触媒機能を備え表面の一部が前記光触媒機能に対して不活性な保護物質により光触媒性結晶が被覆された光触媒微粒子0.05〜20重量部を含有させたクリヤーコーティング組成物を用いて20μmの層厚で被覆層2が形成されている。 (B), the the outer surface of the pole portion 1A1, is formed a primer layer 3A of the two-pack thermosetting urethane-modified acrylic, further to the outer surface of the primer layer 3A, a hydroxyl group-containing fluororesin composition and isocyanate curing agent the coating composition containing a resin solid content per 100 parts by weight of 0.01 to 1.0 parts by weight fluorine-based surfactant, an ultraviolet absorber 1-15 parts by weight, organosilicate compound 1-30 parts by weight, and a photocatalyst a layer of a portion of a surface provided with a function 20μm using photocatalytic inert protective clear coating composition photocatalytic crystal was contained 0.05 to 20 parts by weight photocatalyst fine particles coated with a substance to the function coating layer 2 is formed with a thickness. 被覆層2に含有されるオルガノシリケート化合物及び光触媒微粒子中の光触媒性結晶により、被覆層2表面に高度な親水性が発現され、ポール部1A1の外面に付着した煤塵や塵埃等が、雨水等が降り注がれることで洗い流されやすくなり、表面が清浄に保たれるようになされる。 Organosilicate compound is contained in the coating layer 2 and the photocatalytic crystal photocatalyst microparticles, high hydrophilicity is expressed in the coating layer 2 surface, dust and dust adhering to the outer surface of the pole portion 1A1 is, rainwater showered be easily washed away by, it is done so that the surface is kept clean.

またポール1A1の外面に貼着された反射シート1A3は、プライマー層3Aを介して貼着されている。 The reflective sheet 1A3 which is attached to the outer surface of the pole 1A1 are bonded via the primer layer 3A. 一般に反射シート1A3はポリウレタン系樹脂に対しての密着性が低く、プライマー層を介して貼着して密着性を確保するものであるが、一方被覆層2についても単独でポール部1A1に対する必要十分な密着性が得られるとしても、ポール部1A1が可とう性のポリウレタン系樹脂であることから、ポール部1A1の変形により被覆層2の割れ等が発生する恐れがある。 Generally reflective sheet 1A3 has low adhesion with respect to polyurethane resin, but is intended to ensure adhesion by sticking through a primer layer, whereas necessary and sufficient for the pole portion 1A1 even alone for the coating layer 2 even Do adhesion can be obtained, since the pole unit 1A1 is a polyurethane-based resin flexible, there is a possibility that cracking or the like of the coating layer 2 is generated by the deformation of the pole portion 1A1. ポール部1A1の全体にプライマー層3Aが形成され、プライマー層3A上に被覆層2が形成され且つ反射シート1A3が貼着されることで、反射シート1A3の密着性が確保されると共に、被覆層2はプライマー層3Aが介在することで密着性を向上させ割れ等の発生の恐れを小さくできるが、ポール部1A1外面にプライマー層3Aを形成する際に、反射シート1A3の貼着部分のみを塗り分ける必要などがなく、ポール部1A1外面全体にプライマーを塗布して更に工程を簡便なものとできる。 Primer layer 3A is formed on the entire pole portion 1A1, that the coating layer 2 is formed and a reflection sheet 1A3 on the primer layer 3A is adhered, the adhesion of the reflective sheet 1A3 is secured, the covering layer 2 is a fear of occurrence of cracks to improve the adhesion by the primer layer 3A is interposed can be reduced, at the time of forming the primer layer 3A on the pole portion 1A1 outer surface, coating only stuck portion of the reflective sheet 1A3 no such need to separate, further possible procedure as simple by applying a primer to the entire pole portion 1A1 outer surface.

ポール部1A1の外面にプライマー層3Aを形成するためのプライマーとしては、ポリウレタン系樹脂及び被覆層に対して高い密着性が得られるものであれば特に限定されるものではなく、1液又は2液の湿気硬化型ウレタン系プライマー、1液又は2液の熱硬化型ウレタン系プライマー、2液エポキシ変形ウレタン系プライマー、2液湿気硬化型エポキシ樹脂等を好適に用いることができるが、とりわけ架橋性を有するものを用いるのが好ましく、例えばポール部1A1がウレタン系樹脂からなるものであれば、ウレタン変性アクリル系プライマーを用いることで高い密着性及びポール部1A1に対する追随性が得られて耐久性を高いものとすることができる。 The primers for forming the primer layer 3A on the outer surface of the pole portion 1A1, but the present invention is not particularly limited as long as a high adhesion to polyurethane resin and the coating layer is obtained, one-part or two-part moisture-curable urethane primer, 1 liquid or two-liquid thermosetting type urethane primer, two component epoxy-modified urethane primer, but a two-liquid moisture-curable epoxy resin or the like can be suitably used, especially the crosslinking it is preferred to use those having, for example, as long as the pole portion 1A1 is formed of a urethane resin, high durability followability can be obtained against the high adhesion and the pole portion 1A1 using a urethane modified acrylic based primer it can be a thing.

また、反射シート1A3の表面についても同じ被覆層2を設けるようにしてもよい。 Further, there may be provided the same coating layer 2 also the surface of the reflective sheet 1A3. 反射シート1A3はガラスビーズ反射材1A31の上にカバー1A32が設けられて形成されたものであり、カバー1A32の表面に20μm程度の膜厚で被覆層2が設けられていることで、被覆層2に含有されるオルガノシリケート化合物により、被覆層2表面に親水性が発現され、ポール部1A1の外面に付着した煤塵や塵埃等が、雨水等が降り注がれることで洗い流されやすくなり、表面が清浄に保たれるようになされる。 Reflecting sheet 1A3 are those covered 1A32 on the glass beads reflective material 1A31 is formed provided, by covering layer 2 is provided in a thickness of about 20μm on the surface of the cover 1A32, the coating layer 2 the organosilicate compound contained in hydrophilicity is expressed in the coating layer 2 surface, dust and dust adhering to the outer surface of the pole portion 1A1 is easily washed away by rain water or the like is showered, surface It is adapted to be kept clean. 被覆層2の形成においては、ポール部1A1と同様にプライマーを塗布した上で形成してもよいが、反射シート1A3の表面がポリオレフィン系樹脂等の活性水素を有する材料から形成されている場合には、反射シート1A3表面にクリヤーコーティング組成物を直接塗布して被覆層2を形成することもできる。 In the formation of the coating layer 2 may be formed after applying a primer in the same manner as the pole portion 1A1, but when the surface of the reflective sheet 1A3 is formed of a material having active hydrogen, such as a polyolefin resin It may also form a coating layer 2 a clear coating composition directly applied to the reflection sheet 1A3 surface.

光触媒性結晶は、光触媒機能を発現して親水化が図られるものであれば特に限定されるものではなくFe 、Cu O、In 、WO 、Fe TiO 、PbO、V 、FeTiO 、Bi 、Nb 、SrTiO 、ZnO、BaTiO 、CaTiO 、KTaO 、SnO 、ZrO などの金属酸化物半導体材料を用いてよいが、比較的低廉で扱いが簡便である酸化チタンが好適に用いられる。 Photocatalytic crystal, Fe 2 O 3 is not particularly limited as long as it hydrophilization is achieved by expressing a photocatalytic function, Cu 2 O, In 2 O 3, WO 3, Fe 2 TiO 3, PbO , V 2 O 5, FeTiO 3 , Bi 2 O 3, Nb 2 O 3, SrTiO 3, ZnO, but BaTiO 3, CaTiO 3, KTaO 3 , SnO 2, may be a metal oxide semiconductor material such as ZrO 2 , relatively inexpensive and handling is simple titanium oxide are preferably used. また酸化チタンの中でも活性の高いアナターゼ型の二酸化チタンが好適である。 The anatase type titanium dioxide having high activity among the titanium oxide are preferred.
