  • Publication number: 20080111114
    Abstract: A flame-retardant composition comprises a nanocube or metal organic framework having a plurality of porosities formed therein; a flame retardant material occupying the porosities; and a matrix material in which said nanocubes are dispersed. The flame retardant may further comprise a sealant applied to at least a portion of the nanocube, wherein the sealant substantially prevents the gas from escaping the porosities in the nanocube. It may also include a composition wherein the matrix is a flame-retardant composition adapted to be applied to fabric. The invention may also include nanocubes formed of a material that will break down and release the gas in the presence of water or nanocubes formed of a material that will break down and release the gas in the presence of flame. The nanocubes containing the flame retardant material may also be sealed with a sealant that is a polymer material.

  • Patent number: 7354958
    Abstract: The invention provides a photopolymerizable composition comprising: flame-retardant particles which contains a hydrated metal and have an average diameter of about 1 to 500 nm; and a photopolymerization reactive material. The hydrated metal preferably includes at least one selected from the group consisting of a hydrated magnesium, hydrated calcium, hydrated aluminum, hydrated zinc, hydrated barium, hydrated copper and hydrated nickel. A cover layer which comprises an organic compound or a polysilicone is preferably formed on surfaces of the flame-retardant particles. The invention provides a flame-retardant resin-formed article which is formed of the photopolymerized photopolymerizable composition. A flame retardancy of the article measured in accordance with the UL-94 test preferably scores HB or higher.

  • Patent number: 7341620
    Abstract: A sound-absorbing and fire-insulating wall covering includes, a cured mixture of: (i) 5-20% by weight mineralized wood fibre; (ii) 20-60%/by weight sand with an SiO2 content of less than 5% by weight and a greywacke content of at least 30% by weight; and (iii) 20-50% by weight cement. A method of preparing a fire-insulating wall covering includes a step of mixing, relative to the cured weight, 5-20% by weight mineralized wood fibre, 30-60% by weight sand with an SiO2 content smaller than 5% by weight and a greywacke content of at least 30% by weight, and 20-50% by weight cement. Then 10-30% by weight water is added. Thereafter the mixture is cured to form the fire-insulating wall covering.

  • Patent number: 7323509
    Abstract: Fire-resistant structural composites are comprised of a phenolic resin system, reinforcing fibers and alumina tri-hydrate. The composites may be formed into structural or load-bearing parts, and are particularly suited for applications requiring high strength and a high degree of fire-resistance, such as in the automotive, aircraft, or ship-building industry. Optionally, a siloxane modifier may be added to the resin system to improve the flexibility and impact resistance of the composite.

  • Publication number: 20080011988
    Abstract: An activated silicon-containing aluminum complex flame-proofing agent containing minor amounts of halogen, silicon, oxygen and hydrogen. The silicon being present in amounts of at least trace and having a hexagonal structure; the ratio oxygen to hydrogen in the complex usually being 16:18 and the process for making such complex comprises the steps of treating substantial pure aluminum with acid, then with mercury, then with a halogen acid again to form a slurry. The slurry is then applied on paper, paper pulp, cellulose pulp, plywood, clothing, textiles and any structural porous material for flame producing same. Coincidentally, when applied to certain toxic compounds and complexes in a certain way, it renders them non-toxic.
