Description
また、土木建築に用いられる被覆鋼材においては、特許文献1の被覆用樹脂組成物で被覆した被覆鋼材の被膜の応力亀裂や磨耗劣化により長期寿命が期待できないという問題がある。
密度は、JIS K7112に準拠した(g/cm3)。
硬度は、JIS K7215に準拠してタイプDデュロメーターにて評価した(HDD)
破断伸び及び引張強度は、JIS K7113に準拠し評価した(MPa)。
テーバ磨耗試験は、JIS K7204に準拠し、荷重9.8Nを掛け、回転数1000介護の磨耗量を測定した。
鋼板:SPCC−SD 2.3×50×150mm(中目グリッドブラスト)
前加熱温度:200℃(オーブン)
後加熱温度:200℃/2min(オーブン)
接着時間:1min
鋼板脱脂方法
(1)キシレン液に鋼板を2時間浸した。
(2)2時間後、キシレン液から取り出し、ウエス又はガーゼで拭き取った。
(3)アセトンで洗い流した後、200℃に昇温しておいたオーブン中に鋼板を入れ、前加熱を行った。
(1)前加熱した鋼板を熱盤(プレス)の上に置き、目的の接着温度(240〜280℃)上からパウダー(またはシート)を均一に鋼板へ降り掛けた。
(2)鋼板の上にポリテトラフルオロエチレンシート、ステンレス板の順に被せ、プレス(常圧)上で1分間密着させた。
(3)200℃に加熱したオーブンの中で2分間かけて後加熱処理を行い、取り出した後は徐冷にて冷却した。
(4)充分冷却した後、下記の条件で密着力は、剥離試験にて求めた。
前記の剥離試験方法はJIS K6256加硫ゴム及び熱可塑性ゴム−接着性の求め方に準じて行なった。
Claims (4)
