The invention particularly relates to cellulose compounds and microcomposites in which solid materials, liquids, and dispersed or amorphous additives, for example, are coated onto the surface of the cellulose, and methods for the production of said compounds. | 10-30-2008 |
20080265223 | Fire-retardant compositions and methods of making and using same - The present invention provides fire-retardant compositions for treatment of wood products comprising a guanidine phosphate compound and a boron compound, such as boric acid. The present invention also provides a method for using the compositions for preparing a fire-retardant cellulosic material, such as wood, comprising the step of applying a fire-retardant composition comprising an aqueous solution of guanidine phosphate and a boron-containing compound to a cellulosic material, thereby rendering the cellulosic material fire retardant. The present invention also provides a method of preparing a fire-retardant composition comprising mixing a guanidine phosphate and a boron-containing compound. | 10-30-2008 |
20110095245 | Method for Making Fire Retardant Materials and Related Products - A method for making fire retardant material including fire retardant cellulosic insulation. The method includes an arrangement for adding one or more feedstocks and a fire retardancy chemical compound to a common blend tank prior to feedstock drying. The one or more feedstocks may include at least one virgin pulp stock feed and at least one recycled material stock feed. The amount and type of both the virgin feedstock and the recycled material feedstock is selectable. Old newsprint (ONP) may be one type of recycled material feedstock. Another suitable type of recycled material feedstock is old corrugated containers (OCC). The method further includes retaining the fiber feedstock and the chemical compound together for enough time to ensure adherence or impregnations of enough of the chemical to the fibers after the drying process. Fluffing or fiberizing of the treated fibers may be accomplished under less severe conditions than ordinarily employed when making conventional cellulose insulation. | 04-28-2011 |
20110108782 | Flame-retardant wood-based materials - The present invention relates to wood-base materials made flame-retardant with halogen-free organic phosphorus compounds, and to compositions and processes for their production and their use. | 05-12-2011 |
20110155977 | SYSTEM AND METHOD FOR COATING A FIRE-RESISTANT MATERIAL ON A SUBSTRATE - A method for coating a fire-resistant substance onto a carrier veil and products containing fire-resistant substances are provided. The method includes delivering a pliable carrier veil in a traveling web, drawing the carrier veil web through a reservoir defined by a nip of two rollers and containing the fire-resistant substance, where the carrier veil is coated with the fire-resistant substance. The method also includes controlling the amount of fire-resistant substance on the carrier veil web by setting a nip dimension between the two rollers, passing the carrier veil through the nip of the two rollers and providing the fire-resistant substance as a slurry suitable to coat the veil exiting the nip with a layer effective to provide a selected fire resistance. Heat is applied to the carrier veil sufficient to accelerate a curing reaction in the fire-resistant substance. A fire-resistant product includes a glass-based web, and a magnesium oxychloride complex materially coupled to the web, where the complex includes: MgCl | 06-30-2011 |
20110204304 | FLAME RETARDANT COMPOSITION - The ecological flame retardant composition is adapted to protect materials that are flame able. No bromine or borax components are included in the composition. The composition has at least one of a mixture of a predetermined amount of the salts ammonium sulpha and disodium hydrogen phosphate and a mixture of a predetermined amount of water including a predetermined amount of the salts ammonium sulpha, disodium hydrogen phosphate. | 08-25-2011 |
20130126805 | Method For Producing Alkylphosphonous Acid Salts - The invention relates to a method for producing alkylphosphonous acid salts, characterised in that a) a phosphinic acid source (I) is reacted with olefins (IV) in the presence of a catalyst A to obtain an alkylphosphonous acid, the salts or esters thereof (II), b) the thus obtained alkylphosphonous acid, the salts or esters thereof (II) are reacted with metal compounds of Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na, K and/or a protoned nitrogen base to obtain the corresponding alkylphosphonous acid salts (III) of said metals and/or a nitrogen compound, wherein R | 05-23-2013 |
