  • Publication number: 20030044566
    Abstract: An insulation product contains a mixed layer of textile fibers and of natural fibers. A process for manufacturing the insulation product includes passing fibrous bundles of textile fibers and of natural fibers together through an apparatus that divides the textile fibers into segments and that mixes the textile fiber segments with the natural fibers. The bundles of natural fibers can be in the form of specially manufactured mats and/or can be production scraps. The resulting mixture of fibers is formed into a non-woven batt, mat, blanket, or board. The process provides a mixed fibers product, with an improved combination of thermal and acoustic insulation and adequate strength, at a low production cost.

  • Publication number: 20030035963
    Abstract: Adhesive composition for the cementing of a surface layer of a floor covering with a carrier layer of a floor covering includes, a crosslinking adhesive and an antimony- and halogen-free flameproofing agent. The adhesive composition and floor covering are particularly suited for aviation. The fraction of the flameproofing agent may be at least 5% by weight of the adhesive composition. The flameproofing agent may contain ammonium polyphosphate. The adhesive composition makes possible, in a simple and low-cost manner, a cementing of the surface layer with the carrier layer, wherein the requirement of its being highly flame-resistant is accounted for. Moreover, when using the adhesive composition in accordance with the invention, values with regard to combustion gas density and the release of toxic agents clearly fall below acceptable limits governing aviation in cases of fire so that the floor covering is completely suitable for aviation.

  • Patent number: 6270915
    Abstract: A gypsum board/intumescent material ceiling board includes a gypsum board and a fire-resistive barrier. A first major surface of the gypsum board is an upper side for abutting framing and a second major surface of the gypsum board is an underside for facing a room interior. The fire-resistive barrier is a layer of intumescent coating material applied to and coextensive with one of the major surfaces of the gypsum board. The intumescent coating material contains expandable graphite and a corrosion inhibitor in sufficient quantities to provide a corrosion inhibiting layer on metal surfaces, such as the surfaces of metal fasteners, with which the intumescent coating material comes in contact. In addition, the intumescent coating material has a pH greater than 7.0 to reduce corrosive properties of the intumescent material and provide a chemical environment conducive to the forming of the corrosion inhibiting layer by the corrosion inhibitor.

  • Publication number: 20010008689
    Abstract: Adhesive sheets using an acrylic pressure-sensitive flame-retardant adhesive having excellent properties such as adhesive force and holding power at high temperature and also having a self fire-extinguishing property which instantaneously extinguishes fire, i.e., a flame-retardance, are provided. A photopolymerizable composition comprising (a) 100 parts by weight of a monomer (or the oligomer thereof) comprising 70 to 100% by weight of a (meth)acrylic acid alkyl ester having on the average a carbon number of 2 to 14 in the alkyl group and 30 to 0% by weight of a monoethylenically unsaturated monomer copolymerizable with the ester, (b) 0.02 to 5 parts by weight of a polyfunctional (meth)acrylate as a crosslinking agent, (c) 0.01 to 5 parts by weight of a photopolymerization initiator, and (d) 10 to 180 parts by weight of a flame retardant having a melting point of at least 60° C.

  • Patent number: 6248677
    Abstract: A ceramic fiber blanket is inserted into a mold, and ceramic fiber slurry, preferably made with refractory ceramic fibers, binders, and water, is deposited on the blanket. Vacuum pressure is created under the blanket to pull the fibers of the slurry toward the fibers of the blanket to entangle them together. The slurry and blanket is then dried to form a rigid yet surface compliant ceramic fiber composite product with superior thermal insulating and acoustic dampening properties.

  • Patent number: 6228784
    Abstract: There is disclosed a heat resistant cloth for fire fighting. At least an inner surface of a fluororesin film is subjected to plasma discharge treatment to form a treated surface. A vacuum-deposition film made of a bright metal such as aluminum is formed on the treated surface of the fluororesin film without use of a primer. The vacuum-deposition film on the treated surface is bonded to an outer surface of a substrate fabric through use of a silicone rubber adhesive in order to form a heat-reflecting layer on the outer surface of the substrate fabric. Since no primer coating layer is used, the heat reflecting layer can prevent a decrease in brightness, which would otherwise occur due to cracks generated in the primer coating layer. Thus, a decrease in heat reflectivity at high temperature is prevented. Since no flammable synthetic resin layer is used at the surface of the heat reflecting layer, flame resistance can be improved.

  • Patent number: 6228497
    Abstract: A high temperature resistant glass fiber composition consists essentially of glass fibers having a nominal softening point of about 1000° F. (about 538° C.) which is capable of passing the British Standard 476 Part 4 fire test for building materials. The BS476-4 test begins at 750° C., substantially above the nominal softening point of the glass fibers. The increased temperature resistance is provided by coating the glass fibers with a halogenated resin latex binder and a calcium carbonate material. The method of making the glass fiber composition comprises depositing the resin latex and a calcium carbonate material on the glass fibers using a cationic flocculant. The preferred halogenated resin latex binder is selected from polyvinyl chloride and polyvinylidene chloride.

  • Patent number: 6214455
    Abstract: Disclosed in a halogen-free flame-retardant epoxy resin composition, comprising (A) a bisphenol A type epoxy resin, (B) a novolak type epoxy resin, (C) a phenolic resin type curing agent, (D) a curing accelerator, and (E) an inorganic filler. The phenolic resin type curing agent (C) is provided by a nitrogen-containing phenolic resin, preferably, by a co-condensation resin formed by the reaction among a phenolic compound, a guanamine compound, and an aldehyde compound. More desirably, a phenolic resin containing both phosphorus and nitrogen should be used as the curing agent (C). Further, a combination of the co-condensation resin noted above (C-1) and a reactive phosphoric acid ester can be used as a curing agent.

  • Patent number: 6197707
    Abstract: An improved bituminized flame-retardant textile material is provided that effectively overcomes bitumin adhesion difficulties associated with products of the prior art wherein the flame-retardant present on the surface of a textile support interfers with and hinders the achievement of bitumin adhesion. An anti-flame agent is applied in a quantity of 20 to 100 grams per square meter over 30 to 90 percent of the upper surface of the textile support. The remaining portions of the upper-surface of the textile support are free of the anti-flame agent. It surprisingly has been found that the surface portions of the textile support that are free of the anti-flame agent provide areas for the achievement of optimum bitumin adhesion with the textile support while still making possible entirely satisfactory flame retardancy for the overall product.

  • Patent number: H2054
    Abstract: In accordance with the foregoing principles and objects of the invention, the mitigation of fires in machinery enclosures is achieved by strategic placement of thin narrow strips of intumescent material within the ventilated space between the machinery and a housing enclosing the machinery, whereby, in the event of a fire, the resulting flame contacts the intumescent material causing it to swell and to effectively block air flow through the ventilated space.
