Abstract
The invention relates to a water-based flame-retardant composition comprising at least one polyvinylpyrrolidone polymer, at least one silane coupling agent and at least one inorganic compound. The flame-retardant composition has low organic content and low toxicity. The flame-retardant composition may further comprise at least one polymeric emulsion and can be used as a coating or an adhesive. The invention also provides a flame-retardant article comprising a substrate and the flame-retardant composition disposed on a surface of the substrate.
Claims29
A water-based flame-retardant composition comprising:
- at least one polyvinylpyrrolidone polymer,
- at least one silane coupling agent in an amount sufficient for providing wetting property for inorganic compound(s);
- and
- at least one inorganic compound selected from the group consisting of flame-retardant agents, compounds capable of acting as flame-retardant agents, and mixtures thereof, wherein said composition contains no greater than about 20% by weight organic compounds, based on the total weight of the dried composition.
The flame-retardant article of 19, wherein said substrate comprises fiberglass, fiberglass web, mineral wool, construction components of buildings, furnishings, watercraft-ships, submarine, and airplanes.
The flame retardant article of 1, wherein said substrate comprises fiberglass, fiberglass web, mineral wool, construction components of buildings, watercraft-ships, or airplanes.
