Abstract: Improved fire retardants that include guanylurea phosphate [(H2N—C(NH)—NH—C(O)—NH2).H3PO4] (GUP) and boric acid, materials such as wood and composite wood products that include these fire retardants, and methods of making and using same.

Abstract: The invention relates to compositions for the application of coatings primarily to wood and metal structures and installations, which have high fireproofing and thermal insulation properties, and can be used in construction, the aircraft industry, rail transport and shipbuilding. The composition includes a foaming system, which itself includes pentaerythritol or sorbitol, ammonium polyphosphate, boric acid, urea, filler and pigment, and also resin as a binder.

Abstract: A water-based foam fire extinguisher excellent in foaming properties and film-forming properties in a low temperature region which includes an aqueous solution of at least one member selected among potassium hydrogen carbonate, ammonium phosphate, ammonium sulfate, ammonium bromide, boron oxide, and potassium tetraborate and, incorporated in the solution, a freezing point depressant so as to have a freezing point of −20° C. or below, characterized by containing a perfluoroalkylbetaine as a fluorochemical surfactant and one or more amide-amino acid type surfactants represented by general formula (1) and/or (2) (wherein R1 represents C7-23 alkyl, hydroxyalkyl, aralkyl, or alkenyl; and X represents an alkali metal or hydrogen) as hydrocarbon surfactants.

Abstract: Fire retardant cellulosic material comprises from 0.4 to 2.0% by weight of tin and from 0.4 to 8.0% by weight of boron based on the weight of the cellulosic material. The fire retardant material is prepared in a two-stage or a one-stage process. The two-stage process comprises impregnation of the material with an alkaline solution of an alkali metal stannate or stannite, followed by impregnation with an aqueous solution of boric acid and drying. The one-stage process comprises impregnation of the material with a stable aqueous colloidal suspension of hydrous tin oxide stabilized with an alkali metal salt of boric acid having a pH in the range of from 4 to 8, followed by drying.

Abstract: A flame-retardant adhesive film comprises an insulating substrate film, a flame-retardant interlayer provided on the insulating substrate film, and a flame-retardant adhesive layer provided on the flame-retardant interlayer. The flame-retardant interlayer has higher flame retardance than the flame-retardant adhesive layer. The flame-retardant adhesive layer contains a nitrogen-containing organic flame retardant, and the flame-retardant interlayer contains a non-halogen-based flame retardant with better flame retardance than the nitrogen-containing organic flame retardant.
