Patent number: 7879926Abstract: The present invention is a method and composition for controlling the viscosity of latex compositions that include fly ash. The composition is an aqueous dispersion comprising water, at least one polymer latex, from about 50 to about 600 parts by weight fly ash per 100 parts by weight dry polymer, and a viscosity stabilizing composition that preferably comprises at least one borate compound. The method includes adding a viscosity stabilizing composition to an aqueous polymer latex composition that includes fly ash. The viscosity stabilizing composition can be used to produce a stirred viscosity of the aqueous dispersion 7 days after mixing that is less than 30% greater than the viscosity of the aqueous composition immediately after mixing.Type: GrantFiled: December 6, 2006Date of Patent: February 1, 2011Assignee: Boral Material Technologies Inc.Inventors: Max Howard Gregory, Russ Kendal Majors

Publication number: 20110001255Abstract: Methods for forming foamed polyurethane composite materials in an extruder including a vacuum section are described. One method includes introducing a polyol, a di- or poly-isocyanate, and an inorganic filler to a first section of an extruder and mixing the components. After mixing, the composite material is advanced to a second section of the extruder, which is maintained at a vacuum pressure. The composite material can begin foaming in the second section and then be extruded from the output end of the extruder. The vacuum pressure of the second section removes non-foaming related gasses entrained in the composite material. A further method includes directing the extruded composite material into a mold.Type: ApplicationFiled: July 6, 2010Publication date: January 6, 2011Applicant: Boral Material Technologies Inc.Inventor: Marc-Andre Tardif

Publication number: 20110002190Abstract: Methods for forming composite materials containing fiber in an extruder are described. A first method includes introducing a polymeric material, an inorganic filler, and a fiber to an extruder. A fiber metering device is used to control the rate the fiber is introduced to the extruder based on the extrusion rate of the extruder. A further method is described that includes introducing a polymeric material and an inorganic filler to an extruder. Then, downstream of the polymeric material and inorganic filler, a fiber metering device introduces a constant weight percentage of fiber to the extruder based on the amount of polymeric material and inorganic filler introduced to the extruder. After the polymeric material, inorganic filler, and fiber are introduced to the extruder by either method, the components are mixed to produce a composite material.Type: ApplicationFiled: July 6, 2010Publication date: January 6, 2011Applicant: Boral Material Technologies Inc.Inventor: Marc-Andre Tardif

Patent number: 7744019Abstract: An apparatus for mixing a catalyst with a resin and then spraying the mixture onto a surface. The catalyst is mixed with air before the catalyst/air mixture is introduced to the resin in the mixing tube. The sprayer is provided with a specially designed check valve to prevent resin and catalyst from back flowing into the air/catalyst supply line. The construction of the check valve prevents it from clogging or becoming stuck shut during operation.Type: GrantFiled: September 27, 2006Date of Patent: June 29, 2010Assignee: Alphagen Materials Technology, Inc.Inventor: Matthew Merchant

Publication number: 20090297853Abstract: A process for preparing nanoparticle coated surfaces including the steps of electrostatically coating surfaces with polyelectrolyte by exposing the surface to a solution or suspension of polyelectrolyte, removing excess non-bound polyelectrolyte, then further coating the particles with a multi-layer of charged nanoparticles by exposing the polyelectrolyte-coated surface to a fluid dispersion including the charged nanoparticles. The process steps can optionally be repeated thereby adding further layers of polyelectrolyte followed by nanoparticles as many times as desired to produce a second and subsequent layers. The polyelectrolyte has an opposite surface charge to the charged nanoparticles and a molecular weight at the ionic strength of the fluid that is effective so that the first, second, and subsequent layers independently comprise a multiplicity of nanoparticle layers that are thicker than monolayers.Type: ApplicationFiled: June 23, 2009Publication date: December 3, 2009Applicant: Advanced Materials Technology, Inc.Inventors: Joseph J.
