Patent number: 11148970Abstract: The general inventive concepts relate to unbonded loose-fill fiberglass compositions useful for insulation. The compositions demonstrate high hydrolytic stability. In certain instances, this is accomplished by application of a surface modifier. In certain embodiments, the modifying agent is prepared by dilution and hydrolysis of a silane at a high solid content (i.e., hydrolysis at 25% to 60% solid).Type: GrantFiled: June 15, 2016Date of Patent: October 19, 2021Assignee: Owens Coming Intellectual Capital, LLCInventors: Fatemeh Nassreen Olang, William E.

Publication number: 20140001395Abstract: A binder composition, obtained by polymerizing acrylic acid monomer in water in the presence of a cure accelerator comprising an alkali metal salt of a phosphorous-containing inorganic acid to form a low molecular weight polyacrylic acid and subsequently reacting said low molecular weight polyacrylic acid with a polyhydroxy crosslinking agent in a crosslinking step to make a composition suitable for use as a component in a binder for fiberglass. A significant improvement involves conducting the crosslinking step in the absence of added catalyst. Moreover, satisfactory results are obtained in the absence of conventional undesirable sulfur odors.Type: ApplicationFiled: July 29, 2013Publication date: January 2, 2014Applicant: Owens Corning Intellectual Capital, LLCInventors: Liang Chen, William E.

Publication number: 20110021101Abstract: An aqueous binder composition is provided that includes a modified starch and a silane coupling agent, and optionally, a crosslinking agent. The starch from which the modified starch is derived is natural in origin, biorenewable, and is derived from plant sources. The modified starch has been chemically modified from its natural form and may have a degree of polymerization from about 20 to about 4000. Additionally, the modified starches have a low viscosity and cure at moderate temperatures. Advantageously, the modified starches are water dispersible and have excellent resistance to water after curing. In addition, the binder has a light color after being cured. The crosslinking agent may be any compound suitable for crosslinking the starch based compound. In exemplary embodiments, the silane coupling agent is an aminosilane. The environmentally friendly, biorenewable binder may be used in the formation of insulation materials and non-woven chopped strand mats.Type: ApplicationFiled: June 29, 2010Publication date: January 27, 2011Inventors: Christopher M. Hawkins, Liang Chen, Jesus M. Hernandez-Torres, William E. Downey

Publication number: 20110003522Abstract: An aqueous binder composition is provided that includes a protein-containing biomass and a pH adjuster. Optionally, a crosslinking agent and/or a moisture resistant agent may be included in the binder composition. The protein-containing biomass is natural in origin and may be derived from plant or animal sources. The pH adjuster is used to adjust the pH of the binder to a desired pH and lower the viscosity of the protein-based biomass. In addition, the pH adjuster may act as a crosslinking agent. The crosslinking agent may be any compound suitable for crosslinking the protein-containing biomass and reacting with the moisture resistant agent, when the moisture resistant agent is present in the binder. In addition, the binder has a light color after it has been cured. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats.Type: ApplicationFiled: May 10, 2010Publication date: January 6, 2011Inventors: Liang Chen, William E.

Patent number: 7754020Abstract: A recovery system recycles the washwater used to clean excess binder and debris from the production components, including a forming hoodwall constructed of non-corrosive materials, for manufacturing fiberglass insulation. A separate closed-loop recovery system is provided for the forming hoodwall in which the binder-containing washwater is screened and then recycled back to the forming hoodwall without further chemical treatment to change the pH level. A binder reclamation system is coupled to the hoodwall washwater recovery system to divert the low pH washwater when the supply of binder needs replenished at the forming hoodwall. The binder reclamation system introduces an acid solution to the cleaned washwater to lower the pH from about 2.5 to about 3.5. The other production components share a bulk washwater recovery system in which a base solution is introduced to raise the pH to approximately 8 or above to reduce corrosion in the other production components.Type: GrantFiled: February 26, 2007Date of Patent: July 13, 2010Assignee: Owens Corning Intellectual Capital, LLC.Inventors: Harry B. Cline, William E. Downey, Liang Chen, William R. Cooper

Patent number: 7326304Abstract: A neutralization system for controlling the pH of the washwater used to clean and maintain polyacrylic bound glass forming equipment is provided. The neutralization system introduces a base solution to a washwater solution when the pH of the washwater solution contained in a closed loop washwater recovery system and in a washwater tank holding the washwater solution is determined to be below approximately 8.0. Maintaining the pH of the washwater solution reduces the corrosion rate of the glass fiber forming equipment that is typically associated with acidic binders. In a second embodiment of the invention, a closed-loop hoodwall reclaim washwater recovery system utilized in addition to the washwater neutralization system that allows for the recovery and reuse of a polycarboxylic acid binder with a minimal amount of base solution. The closed-loop hoodwall reclaim washwater system is not connected to the closed-loop washwater neutralization system.Type: GrantFiled: May 23, 2006Date of Patent: February 5, 2008Assignee: Owens Corning Intellectual Capital, LLCInventors: Harry B. Cline, William E. Downey, Liang Chen, William R. Cooper

Patent number: 7251959Abstract: A neutralization system for controlling the pH of the washwater used to clean and maintain polyacrylic bound glass forming equipment. The neutralization system introduces a base solution to a washwater solution when the pH of the washwater solution contained in a closed loop washwater recovery system falls below about 8.5, thereby substantially reducing the corrosion rate of the components of the equipment associated with acidic polyacrylic acid binder, maleic acid cobinder or maleic anhydride cobinder and washwater solution. A closed-loop hoodwall washwater recovery system may also be introduced in addition to the neutralization system that allows for the recovery and reuse of polyacrylic acid binder and maleic acid cobinder or maleic anhydride cobinder with a minimal amount of base solution, thereby minimizing degradation of insulation properties of polyacylic acid bound glass fiber products.Type: GrantFiled: December 31, 2002Date of Patent: August 7, 2007Assignee: Owens-Corning Fiberglas Technology, Inc.Inventors: Harry B.
