Abstract
Fire-retardant barriers are described which are useful for protecting military personnel and equipment from both fire and chemical and/or biological agents. The fire-retardant barriers are multilayered structures having desirable flammability characteristics and resistance to chemical and/or biological agents. The preferred barriers also possess favorable durability properties and are printable.
Claims40
A fire retardant barrier comprising:
- a first film component including a plurality of layers containing a fire retardant material, at least one of said plurality of layers being attached to at least one layer of polymeric material to provide resistance to chemical and biological agents;
- and
- a second component attached to the first component including a polymeric material layer for imparting strength to the fire retardant barrier.
A fire retardant barrier comprising:
- a first component including a first layer containing a fire retardant material for resisting chemical and biological agents, and second and third layers on opposite sides of the first layer at least one of which contains a fire retardant material;
- and
- a second component including a layer of scrim woven made of high-density polyethylene material and a layer of low-density polyethylene material.
A multilaminate barrier having a flammability characteristic of less than about 60 seconds based on Federal Test Method 5903 and a resistance to mustard and thickened GD toxicological agents of at least about 4 hours based on Chemical Research and Development Center - Special Procedure 84010;
- wherein said multilaminate barrier includes a first film component including a plurality of layers containing a fire retardant material, at least one of said plurality of layers being attached to at least one layer of polymeric material to provide resistance to chemical and biological agents;
- and
- a second component attached to the first component including a polymeric material layer for imparting strength to the fire retardant barrier.
A multilaminate barrier having a flammability characteristic of less than about 20 seconds based on Federal Test Method 5903 and a resistance to mustard and GD toxicological agents of at least about 50 minutes based on IAW Military Standard - 282;
- wherein said multilaminate barrier includes a first film component including a plurality of layers containing a fire retardant material, at least one of said plurality of layers being attached to at least one layer of polymeric material to provide resistance to chemical and biological agents;
- and
- a second component attached to the first component including a polymeric material layer for imparting strength to the fire retardant barrier.
A fire-retardant barrier, comprising:
- a first component including a plurality of polyolefin-containing layers having a fire-retardant material combined therewith, at least one of said plurality of layers attached to at least one layer of polymeric film, and
- a second component attached to the first component, said second component including a multilayer system made of a high-density polymer sandwiched between two layers of low-density polymer.
