にできて、耐食性及び耐候・性に優れた効果がある。Further, (a) shows the heat collectors of Examples 2 and 3 (film thickness: 5 mm), which has an absorption rate of 0.94 and an emissivity of 0.20, and is excellent in heat resistance, corrosion resistance, and film resistance. In addition, Table 1 (b) shows a selective absorption coating film (film thickness 5 mm) made of a commercially available silicone polyester resin paint.
(c) of Table 1 shows a heat collector having a commercially available selective absorption film (thickness: 1 μm) that has been subjected to chemical conversion treatment. These heat collectors (b) and (c) have no problems in both heat absorption rate and emissivity, but are inferior in durability. Especially high temperature 200o
Continuous heating at 200° C. causes discoloration or poor adhesion, and has the disadvantage that the absorption rate for heat collection and the emissivity for selective absorption deteriorate. As is clear from the above explanation, the present invention
Since a coating film is formed on the surface of the solar heat collecting plate from a black mixed pigment of polyether sulfon resin paint and black pigment, according to the present invention, the heat resistance temperature can be guaranteed for a long period of time up to 250 oo, and the heat resistance can be guaranteed for a long period of time. No deterioration is observed, the coating is thinner, and has excellent corrosion resistance and weather resistance.
