ABSTRACT:
1000 Parts by weight of oil-in-water emulsion contain 10-70 parts by weight of palm kernel oil as reaction layer former, 5-20 parts by weight of poly-ethoxylated sorbitanoleate as emulsifier, 5-25 parts by weight of unsaturated, long chain monocarboxylic acids as inhibitor against hydrogen embrittlement and rusting, 1-25 parts by weight hexamethylenetetramine as stabilizer, fungicide and bactericide, rest deionized water. The emulsion is particularly suitable for cold rolling aluminum and aluminum alloys. The rolled strip materials exhibit excellent surface quality also after high reductions per pass.
