LUBRICATING FILM FOR PLASTIC WORKING AND METHOD FOR FORMING THE SAME, MATERIAL FOR PLASTIC WORKING, METHOD FOR PRODUCING PLASTIC WORKED PRODUCT AND METHOD FOR PRODUCING METAL PIPE OR BAR STEEL

摘要

PPROBLEM TO BE SOLVED: To provide a lubricating film for plastic working having excellent adhesiveness and lubricity in a simple step without requiring a substrate by a chemical conversion treatment and to provide a method for forming the same, a material for the plastic working, a method for producing the plastic worked product and a method for producing a metal pipe or bar steel. PSOLUTION: The lubricating film for the plastic working is provided with a resin layer formed on a base material and having protective functions to protect the film and a wax layer formed on the resin layer and having lubricating functions. The lubricating film is obtained by coating a surface of the base material with a resin-containing liquid containing at least one of an acrylic or a methacrylic acid resin, a urethane resin, a polyester resin, a vinyl acetate resin, a polyvinyl alcohol resin, a polyvinylpyrrolidone resin, a polyamide resin, a phenol resin, an epoxy resin and a polytetrafluoroethylene resin, curing the resin-containing liquid, forming the resin layer, then coating the resin layer surface with a liquid containing a wax having ≥40°C softening point, curing the liquid and forming the wax layer.
