しかしながら、従来の断熱塗料は、可視光で吸収し近赤外領域で反射する顔料や、セラミック又はプラスチックの中空粒子や、ゴム発泡体骨材等の熱伝導率の低い顔料を含有させたものであり、断熱効果は、熱伝導率×厚さによって得られるために、断熱効果を得るためには、塗膜を厚くしなければならない、という問題がある。   However, conventional heat-insulating paints contain pigments that absorb visible light and reflect in the near-infrared region, ceramic or plastic hollow particles, and low thermal conductivity pigments such as rubber foam aggregates. In addition, since the heat insulating effect is obtained by the thermal conductivity × thickness, there is a problem that the coating must be thickened to obtain the heat insulating effect.

また、従来の断熱塗料は、断熱効果を得るためには、塗膜を厚くしなければならない、という問題があるので、舗装面用や、建築物外装面用、プラスチック部品の表面や、金属部品の表面に、塗膜を薄く形成した場合であっても、十分な断熱効果が得られる断熱塗料の開発が、長年、望まれていた。   In addition, conventional heat-insulating paints have the problem that in order to obtain a heat-insulating effect, it is necessary to increase the thickness of the coating film. For paving surfaces, building exterior surfaces, plastic parts surfaces, metal parts, etc. For many years, it has been desired to develop a heat-insulating coating material that can provide a sufficient heat-insulating effect even when a thin coating film is formed on the surface.

本発明は、以上のような問題を解決するためになされたものであって、特に、舗装面用や、建築物外装面用、プラスチック部品の表面や、金属部品の表面に、塗膜を薄く形成した場合であっても、十分な断熱効果が得られる断熱塗料を提供することを目的としている。   The present invention has been made to solve the above-described problems. In particular, a thin coating film is applied to the surface of a pavement surface, a building exterior surface, the surface of a plastic part, or the surface of a metal part. Even if it is formed, it aims at providing the heat insulation coating material from which sufficient heat insulation effect is acquired.

請求項2に記載の断熱塗料は、請求項1に記載の断熱塗料の、シリサイド粒子が、熱や光を電気エネルギーに変化させる機能を有する材料を含む。   The heat insulating paint according to claim 2 includes a material in which the silicide particles of the heat insulating paint according to claim 1 have a function of changing heat or light into electric energy.

請求項3に記載の断熱塗料は、請求項1に記載の断熱塗料の、シリサイド粒子が、Siと金属との化合物シリサイドを含む。   In the heat insulating paint according to claim 3, the silicide particles of the heat insulating paint according to claim 1 include a compound silicide of Si and a metal.

請求項5に記載の断熱塗料は、請求項1に記載の断熱塗料の、シリサイド粒子が、光電変換素子用半導体を含む。   In the heat insulating paint according to claim 5, the silicide particles of the heat insulating paint according to claim 1 include a semiconductor for a photoelectric conversion element.

請求項6に記載の断熱塗料は、請求項1に記載の断熱塗料の、シリサイド粒子が、β−FeSiを含む。 In the heat insulating paint according to claim 6, the silicide particles of the heat insulating paint according to claim 1 contain β-FeSi 2 .

請求項7に記載の断熱塗料は、請求項1〜6のいずれかに記載の断熱塗料の、シリサイド粒子の平均粒子径が、約1μm以上約100μm以下である。   In the heat insulating paint according to claim 7, the average particle diameter of the silicide particles of the heat insulating paint according to any one of claims 1 to 6 is about 1 μm or more and about 100 μm or less.

本発明に係る断熱塗料では、シリサイド粒子の平均粒子径は、約1μm以上約50μm以下であることが、更に、好ましい。   In the heat insulating paint according to the present invention, the average particle diameter of the silicide particles is more preferably about 1 μm or more and about 50 μm or less.

これは、シリサイド粒子の平均粒子径は、約1μm未満であっても良いが、約1μm未満のシリサイド粒子は製造するのにコストがかかること、また、シリサイド粒子の粒子径が、約100μmを超えると、薄膜の塗装面を形成するのが困難になるからである。   This is because the average particle size of the silicide particles may be less than about 1 μm, but it is expensive to produce silicide particles of less than about 1 μm, and the particle size of the silicide particles exceeds about 100 μm. This is because it becomes difficult to form a coated surface of the thin film.

尚、製造のし易さを考慮した場合には、シリサイド粒子の粒子径は、約5μm以上約100μm以下であり、約5μm以上約50μm以下であることが更に好ましい。   In consideration of ease of production, the particle diameter of the silicide particles is about 5 μm or more and about 100 μm or less, and more preferably about 5 μm or more and about 50 μm or less.

請求項8に記載の断熱塗料は、請求項1〜7のいずれかに記載の断熱塗料を、材料の表面に形成する塗膜の膜厚を、約5μm以上約100μm以下の厚さとして使用する。   The heat-insulating paint according to claim 8 uses the heat-insulating paint according to any one of claims 1 to 7 with a film thickness of a coating film formed on the surface of the material as a thickness of about 5 μm to about 100 μm. .

請求項1に記載の断熱塗料は、顔料として、シリサイド粒子を含有しているので、光や熱を電気エネルギーに変換することで、塗装面の温度上昇を防止する。   Since the heat-insulating paint according to claim 1 contains silicide particles as a pigment, the temperature of the painted surface is prevented by converting light or heat into electrical energy.

即ち、請求項1に記載の断熱塗料は、シリサイド粒子を含有しているので、光や熱を電気エネルギーに変換することで、塗装面の温度上昇を防止することができる分、従来の断熱塗料に比べ、塗膜を薄く形成した場合であっても、十分な断熱効果が得られる。   That is, since the heat-insulating paint according to claim 1 contains silicide particles, the conventional heat-insulating paint can be prevented by increasing the temperature of the painted surface by converting light and heat into electrical energy. In contrast, a sufficient heat insulating effect can be obtained even when the coating film is thinly formed.

請求項2に記載の断熱塗料は、請求項1に記載の断熱塗料の、顔料として用いる、シリサイド粒子をその機能から規定するものであり、請求項3に記載の断熱塗料は、請求項1に記載の断熱塗料の、顔料として用いる、シリサイド粒子を、材料から規定するものであり、請求項4に記載の断熱塗料は、請求項1に記載の断熱塗料の、顔料として用いる、シリサイド粒子を、機能材料として規定するものであり、請求項5に記載の断熱塗料は、請求項1に記載の断熱塗料の、顔料として用いる、シリサイド粒子を、更に特定的な機能材料として規定するものであり、また、請求項6に記載の断熱塗料は、請求項1に記載の断熱塗料の、顔料として用いる、シリサイド粒子を、具体的な材料として規定するものであり、いずれも、顔料として用いる材料が、光や熱を電気エネルギーに変換することで、塗装面の温度上昇を防止する。   The heat-insulating paint according to claim 2 stipulates silicide particles used as a pigment of the heat-insulating paint according to claim 1 from the function thereof, and the heat-insulating paint according to claim 3 corresponds to claim 1. Silicide particles used as a pigment of the heat insulating paint according to claim 1 are defined from materials, and the heat insulating paint according to claim 4 is used as a pigment of the heat insulating paint according to claim 1. The heat insulating paint according to claim 5 is defined as a functional material, and the silicide particles used as a pigment of the heat insulating paint according to claim 1 are further specified as a specific functional material, Moreover, the heat-insulating paint according to claim 6 defines silicide particles as a specific material used as a pigment of the heat-insulating paint according to claim 1, both of which are used as a pigment. Materials, by converting the light or heat into electrical energy, to prevent the temperature rise of the coated surface.

即ち、請求項2〜6のいずれかに記載の断熱塗料は、いずれも、顔料として用いる材料が、光や熱を電気エネルギーに変換することで、塗装面の温度上昇を防止することができる分、従来の断熱塗料に比べ、材料の表面に、塗膜を薄く形成した場合であっても、十分な断熱効果が得られる。   That is, in any of the heat insulating paints according to any one of claims 2 to 6, the material used as the pigment can prevent the temperature rise of the painted surface by converting light or heat into electric energy. As compared with the conventional heat insulating paint, a sufficient heat insulating effect can be obtained even when a thin coating film is formed on the surface of the material.

請求項7に記載の断熱塗料では、シリサイド粒子の平均粒子径を、約1μm以上約100μm以下の範囲としているので、材料の表面に、塗膜を薄く形成できる。   In the heat insulating paint according to claim 7, since the average particle diameter of the silicide particles is in the range of about 1 μm or more and about 100 μm or less, a thin coating film can be formed on the surface of the material.

請求項8に記載の断熱塗料は、顔料として用いる材料中に、光や熱を電気エネルギーに変換する材料を含んでいるので、材料の表面に、塗膜を薄く形成した場合であっても、十分な断熱効果が得られる。   Since the heat insulating paint according to claim 8 contains a material that converts light or heat into electric energy in the material used as a pigment, even when a thin coating film is formed on the surface of the material, A sufficient heat insulating effect can be obtained.
