Description

  The present invention relates to a synthetic resin rain gutter for collecting rain water from the eaves of a roof and guiding it to the ground.

  Conventional synthetic resin rain gutters are generally formed by molding a synthetic resin material into a desired gutter shape by extrusion molding or the like.

  Here, the synthetic resin rain gutter is not limited to a general rain gutter installed at the eaves of a roof or the like to collect rain water, but all synthetic resin products for collecting the rain water, for example, It is a general term for eaves, eaves, eaves, water collectors, water stops, and fittings.

In recent years, in order to protect the rain gutter surface, a gutter obtained by coextrusion of a coating layer made of a weather-resistant vinyl chloride resin on the outer peripheral surface of a synthetic resin tubular base material has been filed (for example, Patent Document 1).
JP 2001-173173 A

  By the way, with the upgrading of buildings, maintenance-free, fashion, and the like, the synthetic resin rain gutters used in these buildings are also required to be upgraded and designed according to the buildings.

  However, in conventional synthetic resin rain gutters, the entire surface of the rain gutter is finished in one color of synthetic resin material and is plain, so there are limited options depending on the building to be diversified. As a result, there was a problem of poor design.

  The present invention has been made in view of the above-described conventional problems, and provides a synthetic resin rain gutter capable of selecting various designs with depth according to buildings and the like.

To achieve the above objective,
The synthetic resin rain gutter according to claim 1 has a synthetic resin material molded into a desired rain gutter shape as a base material, and the whole surface is colored in a desired color as the first layer on the base material surface. A synthetic resin base colored coating layer is provided, and on the surface of the base colored coating layer, a second resin layer is further provided with a synthetic resin pattern-forming coating layer on which desired characters, patterns, designs, etc. are drawn, A transparent or translucent protective coating layer having at least durability and weather resistance is sequentially laminated on the surface of the pattern forming coating layer as a third layer.

  In this case, by providing a base colored coating layer made of synthetic resin as the first layer on the surface of the base material, the base material is not limited to the color of the synthetic resin material on which the base material is molded. The base material of the cocoon can be formed in a desired color.

  Further, by further providing a synthetic resin pattern forming coating layer as the second layer on the surface of the base colored coating layer, further desired characters, patterns, designs, etc. are drawn on the surface of the base colored coating layer. A synthetic resin rain gutter can be formed.

  Further, since a transparent or translucent protective coating layer is laminated as a third layer on the surface of the pattern forming coating layer, the color, pattern, etc. of the base colored coating layer and the pattern forming coating layer are changed to the rain gutter surface. In addition to being able to express, it can also protect the surface of the gutter.

  The synthetic resin rain gutter according to claim 2 is characterized in that, in claim 1, the base colored coating layer, the pattern forming coating layer, and the protective coating layer are in the form of a paint film or a thin sheet.

  In this case, the base colored coating layer, the pattern forming coating layer, and the protective coating layer are formed in the form of a paint film or a thin film sheet, and in the case of a paint film, it is easy for each diversified design. In the case of a sheet, a uniform product can be easily handled for a large amount of the same design.

The present invention has the following effects.
According to the synthetic resin rain gutter according to claim 1, by providing a base colored coating layer made of synthetic resin as the first layer on the surface of the base material, the color of the synthetic resin material on which the base material is molded is obtained. Without limitation, the base material of the synthetic resin rain gutter can be formed in a desired color.

  Further, by further providing a synthetic resin pattern forming coating layer as the second layer on the surface of the base colored coating layer, further desired characters, patterns, designs, etc. are drawn on the surface of the base colored coating layer. A synthetic resin gutter can be formed, and even if the characters, patterns, figures, etc. are the same, by combining different colors of the base colored coating layer, the composition has characters, patterns, figures, etc. of different colors A resin gutter can be obtained.

  Further, since a transparent or translucent protective coating layer is laminated as a third layer on the surface of the pattern forming coating layer, the color, pattern, etc. of the base colored coating layer and the pattern forming coating layer are changed to the rain gutter surface. In addition to being able to protect the surface of the rain gutter, the inner pattern forming coating layer and the base colored coating layer float through the protective coating layer and are transparent, and have various colors, patterns, etc. A synthetic resin rain gutter with a design can be obtained.

  In this way, by forming a triple coating layer on the surface of the base material, it is possible to obtain a durable and weather-resistant coating that can cope with the stretchability of the synthetic resin rain gutter.

  According to the rain gutter made of synthetic resin according to claim 2, the base colored coating layer, the pattern forming coating layer, and the protective coating layer are formed in the form of a paint film or a thin film sheet. It is possible to easily cope with individual designs, and in the case of a sheet form, it is possible to easily deal with a uniform large number of identical designs.

  Hereinafter, a synthetic resin rain gutter A according to the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a state in which one embodiment of a synthetic resin rain gutter A according to the present invention is partially sectioned, and FIG. 2 is an enlarged cross-sectional view of an enlarged main part of FIG.

  This synthetic resin rain gutter A uses a synthetic resin material made of vinyl chloride resin or the like as a base material 1 and is formed into a desired rain gutter shape.

  Here, a general eaves bowl for collecting rainwater by installing at the eaves of the roof is illustrated, but all the synthetic resin products for collecting the rainwater such as eaves, collection The same applies to water devices, water stops, joints, and the like.

  Next, a base colored coating layer 2 made of synthetic resin, which is entirely colored in a desired color, is formed on the surface of the base material 1 as a first layer by painting or the like.

  The thickness of the base colored coating layer 2 can be formed with a thickness of about 5 to 30 μm, and preferably with a thickness of 20 μm is suitable for the stretchability of the synthetic resin rain gutter.

  Here, as the synthetic resin for forming the base colored coating layer 2, for example, an acrylic resin, a urethane resin, a fluororesin, or the like is used, and a base made of a synthetic resin material having 5-6 times the elasticity of a metal product. Any material may be used as long as it forms a coating layer that can cope with the stretchability of the material 1.

  Further, the term “painting” is a generic name used by existing coating methods such as spraying, roll coater, flow coater, and dipping.

  Further, as the film forming means, not only can the coating film be formed by the above coating or the like, but also, for example, a colored sheet-like thin film can be fixed to the surface of the substrate 1.

  By providing the base colored coating layer 2 made of synthetic resin on the surface of the base material 1 in this way, the base of the synthetic resin rain gutter A is not limited to the color of the synthetic resin material on which the base material 1 is molded. A color can be formed into a desired color.

  When the color of the synthetic resin material on which the substrate 1 is molded and the base color desired for the synthetic resin rain gutter A are the same color, the surface of the substrate 1 is covered with the base colored coating layer 2. It is also good.

  Subsequently, a synthetic resin pattern-forming coating layer 3 on which desired characters, patterns, designs, etc. are drawn is further formed on the surface of the base colored coating layer 2 by painting or the like as described above.

The handle-forming coating layer 3 can be formed with a thickness of about 3 μm to 10 μm, and preferably with a thickness of 5 μm for the stretchability of the synthetic resin rain gutter.
In addition, since coating etc. and a film formation means are the same as the above, the description is abbreviate | omitted.

  Further, as the synthetic resin for forming the pattern forming coating layer 3, the same synthetic resin as that for the base colored coating layer 2 may be used.

  In FIG. 1, the base colored coating layer 2 is a plain brown color, and a wood grain pattern forming coating layer 3 is formed on the surface thereof. Therefore, the synthetic resin rain gutter A can be formed as if it was made of wood, and a synthetic resin rain gutter A having a new design that has not existed in the past can be provided.

  Of course, combinations other than those illustrated are also various. For example, if the base colored coating layer 2 is a plain white or black, and a pattern-forming coating layer 3 with a stone pattern is formed on the surface thereof, it is made of synthetic resin. The gutter A can be formed as if it were made of stone such as marble.

  Of course, the base colored coating layer 2 and the example pattern forming coating layer 3 can be formed only on the outer cover portion of the synthetic resin rain gutter A requiring design.

  A transparent or translucent protective coating layer 4 having at least durability and weather resistance is laminated and formed on the surface of the pattern forming coating layer 3 as a third layer.

  This protective coating layer 4 may be any layer that forms a transparent inorganic coating film, but has sufficient durability and weather resistance, and the coating film has good elongation and is less likely to crack during processing and cutting. From the point of view, silicon alkoxide-based coating materials, transparent ceramics, and the like can be used.

  The protective coating layer 4 can be formed with a thickness of about 15 to 30 μm, and preferably with a thickness of 20 μm for the stretchability of the synthetic resin rain gutter.

  In this way, the color, pattern, etc. formed in the desired design by the base colored coating layer 2 and the pattern forming coating layer 3 can be seen through the protective coating layer 4 and deepen on the surface of the synthetic resin rain gutter A. It is possible to express a certain design and protect its surface.

  INDUSTRIAL APPLICABILITY The present invention can be effectively used as a synthetic resin rain gutter capable of selecting various designs with depth.

It is a perspective view in the state where one example of synthetic resin rain gutter A concerning the present invention was partially sectioned. It is an expanded sectional view of the state which expanded the principal part of FIG.
