  • Patent number: 9605116
    Abstract: A method for secondary-molding a polymer nano oriented crystal material in accordance with an embodiment of the present invention includes the steps of: heating the polymer nano oriented crystal material so that the polymer nano oriented crystal material changes into a mobile phase or a melt having a dense entanglement network structure; molding the polymer nano oriented crystal material which changed into the mobile phase or the melt including the dense entanglement network in the step; and cooling the polymer nano oriented crystal material, which has undergone the step, until the polymer nano oriented crystal material changes into an ordered phase.
    Type: Grant
    Filed: October 7, 2011
    Date of Patent: March 28, 2017
    Assignees: SUNALLOMER LTD., HIROSHIMA UNIVERSITY
    Inventors: Masamichi Hikosaka, Kiyoka Okada, Junichiro Washiyama, Takeshi Nakajima, Yuka Akiyama, Shingo Ueno

  • Patent number: 8044129
    Abstract: Provided is an aqueous binder for inorganic fibers, which is formaldehyde-free, has excellent strength, and is suitable for use under conditions of weakly acidic to weakly basic, and by which a cured product composed of the binder having excellent strength is obtained, and an thermal and/or acoustical insulation material made of inorganic fiber using the same. The thermal and/or acoustical insulation material is molded by using an aqueous binder for inorganic fibers including: an acrylic resin with an acid value of 350 to 850 mgKOH/g; a crosslinking agent containing at least one dialkanolamine; and a curing accelerator, in which a molar ratio of the total number of the hydroxyl groups and imino groups in the crosslinking agent to the total number of carboxyl groups in the acrylic resin is 0.8:1 to 1.5:1, and in which pH of the binder is adjusted to 6.0 to 8.0 with a volatile basic compound.
