  • DI FORMING WATER-BASED COOLANT OF LAMINATED METAL SHEET AND METHOD OF DI FORMING LAMINATED METAL SHEET
    Publication number: 20150107326
    Abstract: A method of DI forming a laminated metal sheet includes drawing a laminated metal sheet; and redrawing and ironing the drawn laminated metal sheet, wherein a water-based coolant including (a) at least one base selected from the group consisting of alkanolamines and alkali metal hydroxides, (b) a fatty acid, and (c) water is used in the redrawing and ironing, and wherein a total content of the base (a) and the fatty acid (b) is 0.02 to 4% by mass and a ratio of a straight-chain fatty acid having a carbon number of 6 to 12 in the fatty acid (b) is 80 to 100% by mass.
    Type: Application

  • Heat-expandable microspheres, method for producing the same, and application thereof
    Patent number: 8324286
    Abstract: Heat-expandable microspheres include a shell of thermoplastic resin and a blowing agent encapsulated therein having a boiling point not higher than the softening point of the thermoplastic resin, have a maximum expanding ratio not lower than 50 times, and are thermally expanded into hollow particulates having a repeated-compression durability not lower than 75 percent. The method of producing the heat-expandable microspheres includes the steps of dispersing an oily mixture containing a polymerizable component and the blowing agent in an aqueous dispersing medium containing a specific water-soluble compound and polymerizing the polymerizable component contained in the oily mixture.
