  • Publication number: 20090176911
    Abstract: Clays and organoclays which are treated with resorcinol diphosphate and/or bisphenol diphosphate as general nanoparticle particle dispersants and replacements for quaternary amines. The two compounds are used as self-activating and self-dispersing nanoparticles by localizing themselves on the particle surface in a polymer matrix and acting as a nanoparticle dispersants in general, as well as resulting in exfoliation of clays. The exfoliate clays may be used in polymers in lieu of other organic treatments. When these clays exfoliate poorly in a given thermoplastic, they can be added in high loading rates to polymethylmethacrylate and the PMMA-clay masterbatch added to the plastic where the organoclay performed poorly. The resulting material is a desirable nanocomposite material, with good exfoliation of the organoclay obtained in the final receiving thermoplastic.

  • Patent number: 7312271
    Abstract: Methods are provided for making a solution masterbatch containing a diene elastomer in an organic solvent and a reinforcing silica filler dispersed therein, comprising the steps of (a) mixing a precipitated silica having an average particle size substantially equivalent to an average particle size of a powdered silica, with a diene elastomer in a first organic solvent; and (b) desolventizing the mixture to form a solution masterbatch preparation. The use of such desolventized solution masterbatches in vulcanizable rubber compounds results in excellent processing characteristics with improved dispersion of fillers, including polymeric nanoparticles. The compounds also demonstrate improved properties, including reduced hysteresis.

  • Patent number: 7252041
    Abstract: Polyolefin-based pallets capable of passing standard pallet flammability tests are prepared by molding the pallet or one or more subassemblies thereof, of a polyolefin molding resin containing a flame retardant package containing magnesium hydroxide, and optionally alumina trihydrate, and zinc borate. The flame retardants may be supplied as a master batch at a concentration higher than that desired in the pallet or subassembly, in a polyolefin-compatible polymer, and result in pallets having a significantly lower heat release rate.

  • Patent number: 7192996
    Abstract: A method and apparatus for manufacturing small batches of solid paint is disclosed, which method includes a first step of providing a component of the solid paint as a liquid in a heated mixing container that has a base and sides and includes a stirrer for stirring the contents of the container. The next step of the method includes controlling, heating and stirring of the contents of the container and progressively adding other components of the solid paint as solids to the container. The liquid acts as a heat transfer medium that transfers heat from the heated container and from the stirrer to the solids. The mix is heated to a temperature of the solid paint and forms a melt that is a uniform liquid. The final step in the method includes discharging the melt from the container and allowing the melt to cool and form the solid paint.
