The obtained coated plate was put into a hot air dryer, heated to 160 ° C., air-cooled in a room at 26 ° C., and its cooling rate was evaluated. As a result, each of the uncoated aluminum plate and the Maglon 1026 clear containing no zirconium carbide was found. Compared to the surface temperature, the heat dissipation effect caused a rapid decrease of 5 to 7 ° C. 10 minutes after the start of cooling.
The coating film obtained in Example 5 had no defects such as wrinkles, blisters, millets, gloss reduction, peeling, cracks, and the like, and the appearance was good.
実施例６
実施例２に記載のレタンＰＧ−８０クリヤー（関西ペイント株式会社製、商品名、イソシアネ−ト硬化型アクリル樹脂塗料）固形分１００部に対して実施例５に記載の炭化ジルコニウム粉末を３０部配合して実施例６の塗料を製造した。
Example 6
30 parts of the zirconium carbide powder described in Example 5 is blended with 100 parts of solid content of PG-80 clear (trade name, isocyanate curable acrylic resin paint manufactured by Kansai Paint Co., Ltd.) described in Example 2. Thus, the paint of Example 6 was produced.
得られた塗料を乾燥膜厚２０μｍになるように７０×１５０ｍｍに切断した厚み３ｍｍのアルミニウム板に塗装し８０℃で３０分間乾燥をおこなって塗装板を作成した。 The obtained paint was applied to an aluminum plate having a thickness of 3 mm cut to 70 × 150 mm so as to have a dry film thickness of 20 μm, and dried at 80 ° C. for 30 minutes to prepare a coated plate.
得られた塗装板を熱風乾燥機に入れて、１６０℃に加熱後、２６℃の室内で空冷しその冷却速度を評価したところ、無塗装のアルミ板及び炭化ジルコニウムを配合しないレタンＰＧ−８０クリヤーの各表面温度に比べて、放熱効果により、冷却開始後１０分で５〜７℃速く低下した。
実施例６で得られた塗膜はシワ、フクレ、アワ、光沢低下、剥がれ、ワレ等の欠陥がなく外観は良好であった。
The obtained coated plate was put into a hot air dryer, heated to 160 ° C., air-cooled in a room at 26 ° C., and the cooling rate was evaluated. As a result, the unpainted aluminum plate and the ethane -80 with no zirconium carbide were blended. Compared to each surface temperature, the heat dissipation effect caused a rapid decrease of 5 to 7 ° C. 10 minutes after the start of cooling.
The coating film obtained in Example 6 was free from defects such as wrinkles, blisters, millets, gloss reduction, peeling, cracks and the like, and had a good appearance.
