    摘要： An object of the present invention is to make it possible, without necessitating an alkali pretreatment, to form a zinc oxide layer having excellent sliding properties on a hot dip galvanized steel sheet not subjected to alloying after galvanizing and thus having a relatively low degree of surface activity. Another object of the present invention is to make it possible to manufacture a hot dip galvanized steel sheet having higher area ratio of Zn oxide layer formed on a coating surface and larger thickness of the Zn oxide layer. Specifically, the present invention provides a method for manufacturing a hot dip galvanized steel sheet comprising: subjecting a steel sheet to hot dip galvanizing and subsequent temper rolling; bringing the steel sheet into contact with acidic solution having pH buffering capacity; retaining the steel sheet for 1 second to 60 seconds after the contact with the acidic solution; and rinsing the steel sheet with water, to form a zinc oxide layer on a coating surface of the steel sheet, characterized in that the method further comprising: carrying out the temper rolling by either rolling the steel sheet first with a dull roll having Ra≧2.0 μm at rolling reduction rate ≦5% and then with a bright roll having Ra≦0.1 μm at rolling reduction rate ≦3% or rolling the steel sheet first with a bright roll having Ra≦0.1 μm at rolling reduction rate ≦3% and then with a dull roll having Ra≦2.0 μm at rolling reduction rate ≦5%.

    摘要： This invention provides an organic composite coated steel sheet comprising, as the base, a zinc or zinc alloy coated steel sheet, which can be used in automobile bodies and electric appliances. The coated steel sheet has excellent press formability with oil, while having excellent perforation corrosion resistance and excellent corrosion resistance in a rust-contaminated environment. The coated steel sheet comprises a zinc or zinc alloy plated steel sheet having, on its surface, a chromate layer and an organic film formed in that order, in which the organic film has a thickness of from 0.1 to 3.0 .mu.m and comprises (i) an epoxy resin mixture composed of a base resin as prepared by adding at least one basic nitrogen atom and at least two primary hydroxyl groups to the ends of an epoxy resin, and a curing agent for the resin of a polyisocyanate compound, as mixed in a particular ratio by weight of the two, (ii) a composite lubricant comprising a polyolefin wax as prepared through coordination-anionic polymerization using a Ziegler catalyst, and fine powder of a fluorine resin, as combined in a particular ratio by weight of the two, and (iii) a rust preventive additive, as combined in a particular ratio of (i), (ii) and (iii).
