Abstract

본 발명은 내식성을 향상시키고 아울러, 가공식 강판 표면 오일을 피복하지 않고 가공할 수 있도록 가공성을 향상시킨 오일레스 강판의 표면 처리방법에 관한 것이다.This invention relates to the surface treatment method of the oilless steel plate which improved corrosion resistance and also improved workability so that it may be processed without covering a processed steel plate surface oil.

본 발명의 주요 특징은, 강판의 표면에 크롬산을 20~120mg/㎡으로 코팅처리하고 건조시킨 후, 그 위에 수용성 우레탄계 수지를 박막으로 롤코팅에 의해 피복하고, 120~180℃로 가열하여 건조시킨 후 수냉에 의해 냉각하는 것을 주요 특징으로 하는 것이다.The main feature of the present invention, after coating the surface of the steel sheet with chromic acid at 20 ~ 120mg / ㎡ and dried, coated with a water-soluble urethane-based resin on a thin film by roll coating, and dried by heating to 120 ~ 180 ℃ After cooling by water cooling is the main feature.
