  • Patent number: 10294111
    Abstract: The present invention relates to a method of preparing a high hydrophobic silica aerogel having a low tap density and a hydrophobic silica aerogel prepared thereby. The method of preparing a hydrophobic silica aerogel according to the present invention may have good productivity and economic efficiency, because preparation time is reduced by simultaneously performing surface modification and solvent substitution in a single step, and may control a degree of hydrophobicity of the prepared silica aerogel by controlling a surface modification reaction by including a step of adding ammonium hydroxide. Thus, a hydrophobic silica aerogel having excellent physical properties, such as tap density and specific surface area, as well as high hydrophobicity obtained by controlling the degree of hydrophobicity may be prepared.

  • Patent number: 9410077
    Abstract: A method for preparing an ultra-light-weight (ULW) proppant usable in the oil and gas industry. The method uses silane coupling agent and organic acid to modify silica fume (SF) to obtain modified SF that is lipophilic and hydrophobic. The modified SF is used as inorganic phase, and the polymerizable monomer is used as organic phase, and the organic-inorganic composite microspheres are obtained through suspension polymerization. The ULW proppant is obtained by drying, screening, and pre-oxidization of the composite microsphere. The ULW proppant has a density of about 1.109 g/cm3-1.278 g/cm3, which is close to that of water, a crushing rate of <5% at 52 Mpa, and a crushing rate of <7% at 69 Mpa. In the oil and gas industry application, water or salt water can be used to replace the high viscose guanidine gum as carrier, thus reduced cost of fracturing, and reduced environment pollution.

    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.

  • Patent number: 8110037
    Abstract: Methods, treatment compositions and treatment systems are disclosed for forming a detachable and renewable coating on a receptive surface by a process of applying a treatment composition comprising a plurality of hydrophobically modified fumed silica particles colloidally dispersed in a volatile solvent; allowing the volatile solvent to evaporate; and thereby depositing a protective coating on the receptive surface consisting of a layer of the hydrophobically modified particles, which provide a substantially transparent coating with dirt- and water-repellency properties that effectively shed dry particulate soils as well as water from the treated surface or treated article bearing a receptive surface.

  • Patent number: 8034173
    Abstract: A method for processing compositions, compositions obtained by such a process and methods of use are disclosed for forming a detachable and renewable protective coating which is substantially transparent. The inventive process compositions are produced by making a highly concentrated dispersion of hydrophobically modified silica particles in the presence of an optional, yet preferable, disilazane derivative under high shear conditions. These process compositions are intended to be further diluted to final treatment compositions, optionally while adding other functional ingredients.

  • Publication number: 20110204283
    Abstract: The invention provides fumed silica comprising aggregates that have an aggregate size and a surface area that satisfy particular formulas relating aggregate size to surface area, as well as aggregates that exhibit particular viscosity, power law exponent index, and/or elastic modulus characteristics when dispersed in liquid media. The invention also provides processes of preparing such fumed silica by combining a silica precursor with a stream of combustible gas, combusting the stream, and producing a stream of combusted gas and fumed silica particles, wherein dopants are introduced, the time/temperature profile, or history, of the stream of combusted gas and fumed silica particles is adjusted to allow for post-quench aggregate growth, and/or additional silica precursor is introduced into the stream of combusted gas.

  • Patent number: 7938902
    Abstract: Cationically stablished aqueous silica dispersion, method for its production and its use. A method is described for the production of cationically stabilised silica in which silica is cationically stabilised in the form of an aqueous dispersion or a powder by mixing with an acid aminosilane solution. A cationically stabilised silica powder may be obtained by removing the solvent. The cationically stabilised silica dispersion obtained is highly storage stable. Mixing with organic binding agents such as PVA is possible without a significant increase in viscosity. The dispersions are particularly suitable for coating slips for printing media, such as inkjet paper, but also for the surface treatment of substrates, e.g. for the hard coating of plastics, or in parting compounds or abrasives and polishing agents.
