Coated Metal Sheet Method for Manufacturing Same and Exterior Building Material
외장용의 도장 금속판이며, 금속판과, 상기 금속판상에 배치되는 덧칠 도막을 가지고, 상기 덧칠 도막은 0.2~15 체적%의 세공 입자인 광택조정제와 1차 입자인 광택소거제를 함유하고, 상기 도장 금속판은 아래의 수학식을 만족한다. 아래의 수학식중, R, D1, D2및 Ru는 각각, 광택조정제와 광택소거제의 개수 입도분포에서의 광택조정제의 개수 평균 입경(μm), 광택조정제의 97.5% 입자경(μm), 광택소거제의 97.5% 입자경(μm) 및 광택조정제의 상한 입경(μm)이며, T는 덧칠 도막의 막두께(μm)이다. D1/T≤0.7, Ru≤1.2T, R≥1.0, 2.0≤D2/T≤7.0, 13≤T≤20
Provided is a coated metal sheet for exterior use, having a metal sheet, and a top coat film situated on the metal sheet. The top coat film contains 0.2-15 volume percent of a gloss control agent composed of porous particles and a delustering agent composed of primary particles. The coated metal sheet satisfies the following expressions in which, in the number-size distribution of the gloss control agent and the delustering agent, R is the number-average particle diameter (µm) of the gloss control agent, D1 97.5 and D2 97.5 are 97.5% particle diameter values (µm) of the gloss control agent and the delustering agent, Ru is the upper limit particle diameter (µm) of the gloss control agent, and T is the film thickness (µm) of the top coat film. D 1 97.5 / T ¤ 0.7 Ru ¤ 1.2 T R ¥ 1.0 2.0 ¤ D 2 97.5 / T ¤ 7.0 13 ¤ T ¤ 20.
