従来、玄関扉の表層等については耐候性のあるオレフィン系化粧シートが使われてきたが、実際の屋外暴露や促進耐候性試験にて耐侯性は評価しており、太陽光の紫外光領域に対しては処方を施した設計ではあったが、赤外光領域の熱の吸収に対しては、考慮されていなかった。 Conventionally, olefin-based decorative sheets with weather resistance have been used for the surface of entrance doors, etc., but weather resistance has been evaluated by actual outdoor exposure and accelerated weather resistance tests, and in the ultraviolet region of sunlight. On the other hand, although it was the design which gave the prescription, it was not considered about the absorption of the heat | fever of an infrared region.
実際に使用されていると、耐候性としては満足されるものであったが、太陽光の赤外光領域の熱の吸収によって、蓄熱作用が発生し、結果として基材に伝わる事で、熱膨張が発生し、表裏の温度差によって反りが発生する慢性的な問題については、解決されないままであった。 When actually used, the weather resistance was satisfactory, but the heat storage effect occurred due to the absorption of heat in the infrared light region of sunlight, and as a result, it was transferred to the base material. The chronic problem of swelling and warping due to temperature differences between the front and back remained unresolved.
本発明はこのような問題を解決するためになされたものであり、すなわちその課題とするところは、短納期で安価に製造可能であり、耐候性や耐摩耗性、耐水性等の各物性に優れ、かつ光線遮蔽効果を有しながら、しかも絵柄の深み等の意匠性にも優れた遮熱化粧シートを提供することにある。 The present invention has been made to solve such a problem, that is, the problem is that it can be manufactured at a low cost with a short delivery time, and has various physical properties such as weather resistance, wear resistance, and water resistance.
