TRANSPARENT HEAT BLOCKING AND HEAT INSULATING MEMBER AND METHOD FOR MANUFACTURING THE SAME

To provide a transparent heat blocking and heat insulating member that is excellent in corrosion and degradation resistance in a salt water resistance test assuming a severe external environment, while maintaining high heat blocking performance and heat insulating performance.SOLUTION: A transparent heat blocking and heat insulating member disclosed in the present application comprises a transparent substrate and a functional layer formed on the transparent substrate. The functional layer includes an infrared reflection layer and a coating type protective layer in this order from the transparent base material. The coating type protective layer is composed of a plurality of layers. At least one layer of the layers other than a layer located on the outermost surface, of the coating type protective layer, is formed of a layer including a (meth)acrylic copolymer having a hydroxyl value of 30 mgKOH/g or more and 200 mgKOH/g or less, and a polyisocyanate cross-linking agent reacting with a hydroxyl group as a resin component before curing. In the coating type protective layer, the layer located on the outermost surface is formed of a layer including an active energy ray curable resin as a resin component before curing and having a thickness of 60 nm or more.SELECTED DRAWING: Figure 1 【課題】高い遮熱性能及び断熱性能を維持したまま、過酷な外部環境を想定した耐塩水性試験における耐腐食劣化性に優れた透明遮熱断熱部材を提供する。【解決手段】本願で開示の透明遮熱断熱部材は、透明基材と、前記透明基材の上に形成された機能層とを備え、前記機能層は、前記透明基材側から赤外線反射層及び塗布型の保護層をこの順に含み、前記塗布型の保護層は、複数の層から成り、前記塗布型の保護層の内、最外表面側に位置する層以外の層の少なくとも１層は、硬化前樹脂成分として、水酸基価が３０ｍｇＫＯＨ／ｇ以上２００ｍｇＫＯＨ／ｇ以下の（メタ）アクリル系共重合体と、該水酸基と反応するポリイソシアネート系架橋剤とを含む層から成り、前記塗布型の保護層の内、最外表面側に位置する層は、硬化前樹脂成分として、活性エネルギー線硬化型樹脂を含み、厚さが６０ｎｍ以上の層から成る。【選択図】図１
