    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.

    Abstract: The invention relates to a method for the surface treatment of inorganic pigment particles with agglomerates of fine primary particles or single crystals of inorganic compounds, particularly of oxides or sulphates. The method is characterized in that the inorganic compounds are first precipitated from an aqueous solution under suitable pH conditions in a separate vessel in the form of fluffily structured agglomerates and/or single crystals. The precipitation product is subsequently added to an aqueous suspension of inorganic pigment particles. The method is particularly suitable for the surface treatment of titanium dioxide particles, in order to achieve high hiding power or high opacity when used in emulsion paints or laminates.

  • Publication number: 20120058877
    Abstract: An object of the present invention is to provide a low thermal expansion filler for low thermal expansion glasses which has a low coefficient of thermal expansion and exhibits superior flowability in a molten state, and a glass composition containing the same. It has been found that a low thermal expansion filler composed of a hexagonal zirconium phosphate powder where a specific particle size of 0.8 ?m to 50 ?m is 95% or more on a volume basis has excellent low thermal expansion property and excellent flowability, and a glass composition containing the filler has been accomplished.

  • Publication number: 20110245397
    Abstract: The invention provides a dispersion of zirconium oxide having a content as high as 20% by weight or more, but a low viscosity, and having a high transparency, which has a transmittance of 35% or more at a wave length of 400 nm, a transmittance of 95% or more at a wave length of 800 nm, and a viscosity of 20 mPa·s or less at a temperature of 25° C. Such a dispersion of zirconium oxide can be obtained by reacting a zirconium salt with an alkali in water to obtain a slurry of particles of zirconium oxide; filtering, washing, and repulping the slurry; adding an organic acid to the resulting slurry in an amount of one mole part or more per mole part of the zirconium in the slurry; hydrothermally treating the slurry at a temperature of 170° C. or higher; and washing and concentrating the resulting aqueous dispersion of particles of zirconium oxide.

  • Patent number: 8016936
    Abstract: Disclosed herein is a method of calcining particulate material, such as kaolin. The method comprises providing a feed mixture comprising a particulate material, such as hydrous kaolin, wherein at least a portion of the particulate feed is coated with a liquid fuel. The method further comprises heating the particulate feed mixture to calcine the particulate feed and burn the liquid fuel to form a calcined product. The liquid fuel coating can act as a secondary, indirect heat source for calcining. The overall calcining temperatures and/or times can be reduced as a result of adding the liquid fuel.
