Description

本発明は、住宅等建築物の屋内や外板、コンテナ、乗用車、冷凍車等の運搬車両の屋根や外壁、船舶、プラント、物置、畜舎等の屋根や外壁等に適用することにより、日光照射、内部発熱に起因する内部温度の上昇を制御し、しかもデザインや美観を損なわない吸放熱塗料およびそれを用いる塗装系に関するものである。   The present invention is applied to roofs and outer walls of transport vehicles such as indoors and outer panels of buildings such as houses, containers, passenger cars, and refrigeration vehicles, roofs and outer walls of ships, plants, storages, barns, etc. The present invention relates to a heat-absorbing and heat-dissipating paint that controls an increase in internal temperature caused by internal heat generation and that does not impair the design and aesthetics, and a coating system using the same.

建築物や建造物の屋根や外板、内壁は、美観を向上させるために、塗料による塗装が行われているが、住宅等の建屋は、直射日光にさらされ、又、ＯＡ機器の普及で室内温度が上昇している。一般の塗装では居住性向上のために内部温度上昇を抑える作用が無いため、温度調整のためのエアコン等の冷房費用が増加し、ひいてはＣＯ２排出、地球温暖化にも影響を与えている。   The roofs, skins, and inner walls of buildings and buildings are painted with paint to improve the aesthetics, but buildings such as houses are exposed to direct sunlight and the spread of OA equipment. The room temperature is rising. In general painting, there is no action to suppress the rise in internal temperature for improving the comfortability, so the cost of cooling the air conditioner and the like for temperature adjustment is increased, which in turn affects CO2 emissions and global warming.

吸放熱を有する技術は近年研究されており、例えば、スポーツウエアなどに応用されている。例えば、下記文献では高度な温度規制をCiba専門化学製品から作り出す織物処置が紹介されている。
インターネットウエブサイトhttp://www.ciba.com/ja/2004_ciba_ehs-report_ja.pdf#search='CIBA ENCAPSULENCE' A technology having heat absorption and release has been studied in recent years, and is applied to, for example, sportswear. For example, the following literature introduces textile treatments that create advanced temperature regulation from Ciba specialty chemicals.
Internet website http://www.ciba.com/en/2004_ciba_ehs-report_en.pdf#search='CIBA ENCAPSULENCE '

これによれば、Ciba ENCAPSULENCE PC140（織物とファブリックの使用のためのマイクロカプセルに入れられた段階変化材料）の紹介がなされ、Ciba ENCAPSULENCE PC140は、伝統的な罠にかけられた空気絶縁から急進的なシフトを意味すること、Ciba Specialty ChemicalsのWaterとPaper Treatment Segmentはミクロ粒子の形で段階変化材料を開発したこと、そして、織物とファブリックの範囲内で利用されるとき、これらのカプセルは着用者の体でインタラクティブに動き、この製品は、したがって、熱を保存することができて、体をより暖かくてより極端な環境および温度状況でより長く快適にしておくことができることが記載されている。   According to this, Ciba ENCAPSULENCE PC140 (stage-change material encapsulated in microcapsules for use in fabrics and fabrics) was introduced, and Ciba ENCAPSULENCE PC140 was radically developed from traditional glazed air insulation. Meaning a shift, Water and Paper Treatment Segment of Ciba Specialty Chemicals has developed a step change material in the form of microparticles, and when used within fabrics and fabrics, these capsules are Moving interactively with the body, this product is therefore described as being able to conserve heat and keep the body longer and more comfortable in warmer and more extreme environmental and temperature situations.

「固体および液体の形の間で、段階変化材料は、熱を吸収するか、保存するか、放つ。熱は冷却に関して解放されることができて、暖房上で吸収されることができる。身体活動の間、着用者の過度の体熱は増加して、カプセル化された段階変化材料に集中する。活動が終わって、本体は冷却し、そして、マイクロカプセルは保存された熱を着用者に返す」「Ciba ENCAPSULENCE PC140のミクロ粒子は、多種多様なアプリケーションに応用でき、繊維、ファブリック、冷凍、自動車、建物、熱交換器、電子機器、床カバー、エネルギー保管所有物が標準的使用に置かれることができる」とある。   “Between solid and liquid forms, the phase change material absorbs, stores, or releases heat. Heat can be released with respect to cooling and absorbed on heating. During activity, the wearer's excessive body heat increases and concentrates on the encapsulated phase change material, after the activity is over, the body cools, and the microcapsules provide stored heat to the wearer. "Return" "Ciba ENCAPSULENCE PC140 microparticles can be applied to a wide variety of applications, fiber, fabric, refrigeration, automobiles, buildings, heat exchangers, electronics, floor coverings, energy storage properties are put into standard use I can do it. "

前記吸放熱を有する技術による吸放熱材は、繊維に練りこむ等で体温との関係に限定されている、又、壁材等に混合されて使用されている例も有るが、混合量が多くなる為経済的ではない。   The heat-absorbing and heat-dissipating material by the technology having the heat-absorbing and heat-dissipating method is limited to the relationship with the body temperature by kneading into the fiber, etc. So it is not economical.

（吸放熱の測定）
以上のようにして得た組成物のそれぞれについて、吸放熱効果を測定した。各組成物を刷毛にて鋼板に表１、表２に記した塗膜に塗装し測定した。結果を表１に示した。測定時間は各３０分とし、箱内温度を測定した。 (Measurement of heat absorption and release)
About each of the composition obtained as mentioned above, the heat absorption-and-release effect was measured. Each composition was applied to a coating film shown in Tables 1 and 2 on a steel plate with a brush and measured. The results are shown in Table 1. The measurement time was 30 minutes each, and the temperature in the box was measured.

吸放熱材含有塗料のみで塗り重ねる、表面温度は同じでも裏面温度、箱内温度に効果が発現する。これは表面温度が上昇した一部を吸放熱材含有塗膜が吸熱し、熱を一時的に蓄えているからである。蓄えられた熱は、吸放熱材の設定温度以下に箱内がなれば放熱される。

Figure 2009280663
Even if the surface temperature is the same, the effect is exhibited in the back surface temperature and the temperature in the box. This is because the heat-absorbing and heat-dissipating material-containing coating absorbs a part of the surface temperature and temporarily stores heat. The stored heat is dissipated if the inside of the box falls below the set temperature of the heat absorbing / dissipating material.
Figure 2009280663

上塗塗料に日射反射率の高い塗料を適用すると、表面温度が下がり、裏面、箱内温度に吸放熱材含有塗膜の効果が更に発現する事が分かる。

Figure 2009280663
It can be seen that when a paint having a high solar reflectance is applied to the top coating, the surface temperature is lowered, and the effect of the heat-absorbing and heat-absorbing material-containing coating film is further exhibited on the back surface and the box internal temperature.
