  • Patent number: 9193837
    Abstract: A composite material having polymeric resin with disperse phases of reinforcing fibers and nanoparticle materials and its manufacture is disclosed herein. The nanoparticles may be bound together and added to the polymeric resin as microscale aggregations, and then unbound to create a disperse phase of nanoparticles in the resin. In other embodiments, the nanoparticles may be bound to a substrate, such as long fibers, and added to a polymeric resin. The nanoparticles are then unbound from the substrate and dispersed throughout the polymeric resin. The polymeric resin may have multiple components where one component may control the dispersion of the nanoparticles.

  • Patent number: 9187608
    Abstract: Polymer extruded or expanded foams that contain modifier-free nanoclays are provided. The addition of modifier-free nano-clays to extruded or expanded foam products improves the thermal properties, mechanical properties, and fire performance properties. Water or a water-containing compound is used as a carrier for the modifier-free nanoclays. The final foamed products may be utilized in building application such as foamed insulation products and in underground applications such as highway insulation. A preferred modifier-free nanoclay is Na+MMT. Modifier-free nanoclay particles may be injected into a polymer during an extrusion foaming process. In another embodiment of the invention, polymer beads containing water/nanoclay particles are formed using inverse emulsion/suspension polymerizations and expanded or extruded into a foamed product. In a further embodiment, a modifier-free nanoclay particle is encapsulated in a super-absorbent material, which may be used in an expanding or extruding process.

  • Patent number: 8748528
    Abstract: Disclosed is a coating composition that includes an aqueous emulsion of a hydrophobic acrylic polymer, a water-soluble polymer, and an inorganic filler, and further includes a freezing-point lowering component to permit low temperature application. The freezing-point lowering component will preferably include a water-soluble, corrosion inhibiting salt. The coating composition will also optionally and preferably include an evaporation enhancing component to promote faster drying and skin formation at low temperatures. The coating composition may be coated onto a construction surface (e.g., by spraying) where, after drying, it will form a fully adhered barrier membrane that is water-vapor permeable, but air and liquid-water impermeable. Such membrane will preferably have sufficient coating thickness and sufficiently high elongation that it will bridge joints and cracks.
