  • Publication number: 20240140071
    Abstract: A resin-coated metal sheet for containers includes a metal sheet and oriented films coating both surfaces of the metal sheet and made of a polyester resin, wherein the polyester resin includes 92 mol % or more of an ethylene terephthalate unit, the full-width at half maximum of a C?O peak at 1725 cm?1±5 cm?1 is 20 cm?1 or more and 25 cm?1 or less in Raman spectroscopy in an orientation direction of the surfaces of the films after coating the metal sheet, and the ratio (I1725/I1615) of the C?O peak intensity at 1725 cm?1±5 cm?1 to the C?C peak intensity at 1615 cm?1±5 cm?1 is 0.50 or more and 0.70 or less in the Raman spectroscopy.

  • Patent number: 9458328
    Abstract: Emulsion paint type damping coatings show an excellent film forming property even if it leaves at low temperature from 5 to 20° C. It does not generate a defective coated film like swellings after baking drying and brings out an excellent damping performance within a range of 20 to 60° C. That is, it contains one or more than two kinds of organic chemicals within a range of 0.5% to 5% by weight in total and the MFT, the minimum film forming temperature of the entire resin emulsion is within a range of 5 to 15° C. and the boiling point for a film forming assistant is within a range of 150 to 240° C., thus, it enables to obtain an excellent film forming property at 5° C. and even in baking drying and does not generate a defective coated film like swellings as well. As a result, emulsion paint type damping coatings bring out an excellent damping performance within a range of 20 to 60° C.

  • Patent number: 8789651
    Abstract: To absorb a noise produced by an external force that generates an audio frequency even if it is applied thereto, and to make it hard to become a noise source to a surrounding area. It includes a surface layer 20 having microscopic pores 21 formed on a surface 20A, communicating passages 24 communicating with the microscopic pores 21 and a porous layer 10 having sound pores 14 that are formed at an inner part deeper than the surface layer 20 having the microscopic pores 21 formed, communicate with the communicating passage 24 and that have a volume larger than volumes of the microscopic pore 21 formed on the surface 20A and the communicating passage 24. A sound absorption characteristic and/or a sound insulation characteristic is provided by the microscopic pores 21 of the surface 20A, the communicating passages 24 of the porous layer 10, and the sound pores 14 of the porous layer 10.

  • Publication number: 20130119165
    Abstract: A coating nozzle for a high-viscosity paint is equipped with an introduction passage, an inner space, and a nozzle slit, which communicate with one another, and sprays a coating body with the high-viscosity paint from the nozzle slit in a radial direction. The nozzle slit is constructed in a sectional shape having a predetermined angle in a plan view. When the nozzle slit is regarded as having the sectional shape, an arc of the sectional shaped nozzle slit serves as a nozzle slit outlet. The nozzle slit outlet has a nozzle slit outlet width equal to or larger than 35 mm and a flattening equal to or smaller than 0.01 where a slit height represents a clearance of the nozzle slit outlet, the nozzle slit outlet width represents a chord of the arc, and the flattening represents a ratio of the slit height to the nozzle slit outlet width.

  • Publication number: 20100113627
    Abstract: This invention provides a water-based coating-type damping material whereby detachment or deformation of a sealer can be prevented and anti-blister performance can be improved. Such water-based coating-type damping material comprises at least an aqueous resin emulsion, an inorganic filler, a water retention agent that retains the moisture of the resin emulsion, and microballoon particles comprising balloons encapsulating an expansion agent that is evaporated by heating so as to expand, the microballoon particles starting to expand in the presence of the expansion agent under heating temperature conditions of the water boiling point or lower.
