  • Patent number: 9334387
    Abstract: The method for the preparation of epoxy-clay nanocomposites uses high shear mixing of Nanomer I.30 E nanoclay into the diglycidyl ether of bisphenol A (DGEBA) epoxy by optimization of high shear mixing speeds, mixing times and degassing temperature. The results showed that the optimum high shear mixing speed and mixing time for optimal clay dispersion were 6000 rpm and 60 min, respectively. Increasing the degassing temperature from 65° C. to 100° C. for the first two hours of the degassing process enhanced nanoclay dispersion, resulting in nanocomposites with a morphology dominated by disorder intercalation with some exfoliated structure. This enhancement in nanocomposite morphology can be attributed to the improvement in epoxy diffusion into the intergallery spacing between clay layers due to temperature rise.

  • Publication number: 20140142215
    Abstract: The present invention relates to hydrophobic gypsum and to a process for making gypsum hydrophobic, in particular it relates to a powdered hydrophobing additive, a hydrophobic gypsum composition and method for preparing same using granules containing organosilicon compounds as hydrophobing additives. The invention provides a granulated additive for rendering gypsum material hydrophobic, comprising a particulate carrier on which is deposited an organosilicon component, a binder polymer and an emulsifier for the organosilicon component. Such a granulated hydrophobic additive is able to provide a high initial hydrophobicity to gypsum materials to which it is applied and that the obtained hydrophobicity can last during a long period of time.

  • Patent number: 8404347
    Abstract: Amphiphilic, magnetic composite particles are comprised of cores and shells. The core contains both hydrophobic vinylic graft copolymer, hydrophobic vinylic homopolymer and magnetic nanoparticles, and the shell to which the hydrophobic vinylic polymer is grafted is a hydrophilic, nitrogen-containing polymer. Typically, the composite particles are made by a process which involves generating radicals on nitrogen atoms of the water-soluble polymer, and then initiating free-radical copolymerization of said vinylic monomer(s) and vinylic-coated magnetic nanoparticles, whereby vinylic polymer(s) undergo(es) phase separation and the vinylic coated magnetic nanoparticles are encapsulated within the vinylic polymer to form a composite latex.
