  • Publication number: 20140102332
    Abstract: Disclosed are a functional reinforcing filler including inorganic particles surface-modified with an alkenylsilanol obtained by hydrolyzing an alkenylalkoxysilane compound, and a method for preparing the same. Since the disclosed functional reinforcing filler has a functional group having a double bond, it has good reactivity for styrene-butadiene rubber and sulfur. Thus, when used as a functional reinforcing filler in the manufacture of rubber, it allows improvement of physical properties through adjustment of the addition amount of sulfur without additional use of the coupling agent. In addition, because of superior hydrolysis reactivity, the problem of alcohol can be solved and a rubber mixture with long scorch time can be prepared. In particular, when the functional reinforcing filler of the present invention is used in the manufacture of tires, improvement in modulus, tensile strength, rotational resistance and wet traction performance can be expected.

  • Publication number: 20090211494
    Abstract: Disclosed is a method for producing ultrafine particles of a Prussian blue-type metal complex wherein (A) an aqueous solution containing an anionic metal cyano complex having a metal atom M1 as the central metal is mixed with an aqueous solution containing metal cations of a metal atom M2 for precipitating a crystal of a Prussian blue-type metal complex having the metal atom M1 and the metal atom M2; then (B) a solution obtained by dissolving a ligand L in a solvent is mixed with the crystal of the Prussian blue-type metal complex for forming a dispersion liquid of ultrafine particles of the Prussian blue-type metal complex; and the (C) the Prussian blue-type metal complex is separated from the dispersion liquid as nanometer-sized ultrafine particles.

  • Patent number: 7553365
    Abstract: An aqueous pigment dispersion is produced by ultrafinely dispersing a pigment dispersion mixture, which has been obtained by mixing at least a pigment and a dispersant in an aqueous medium, with microbeads having diameters of not smaller than 0.02 mm but smaller than 0.2 mm. A color composition for a color filter is produced by dispersing a mixture of a pigment, a dispersant, a resin varnish and a solvent with the microbeads in a mill.

  • Patent number: 7550041
    Abstract: The invention pertains to a highly concentrated pigment comprising from 75 to 95% by weight, preferably from 78 to 95% by weight, most preferred from 80 to 95% by weight, based on the weight of the composition, of a pigment; from 0 to 20% by weight, preferably from 5 to 18% by weight, based on the weight of the composition, of a resin; the total of pigment and resin being from 85 to 98% by weight of the composition; and from 1 to 15% by weight, preferably from 2 to 15% by weight, most preferably from 5 to 15% by weight, based on the weight of the composition, of a C10-C18 alcohol, a liquid hydrocarbon having a boiling point higher than 80° C. at 105 Pa, or both a C10-C18 alcohol and a liquid hydrocarbon having a boiling point higher than 80° C. at 105 Pa. Also claimed are a process for its manufacture, comprising dry-milling, blending and kneading the components, and the use of the pigment concentrates for the preparation of a masterbatch, ink, coating, plastic material, toner or colour filter.

  • Publication number: 20090020042
    Abstract: The present invention relates to the use of nanoparticles for the preparation of water-based dispersion adhesives, and especially the use of finely divided barium sulfate therein. The nanoparticles can be used with or without chemical modification. Adhesives of this kind feature improved properties, examples being improved cohesion in conjunction with comparable adhesion and higher heat resistance. Preference is given to dispersion adhesives based on polyacrylate, polyurethane, and epoxy resin.
