Abstract
Fire-resistant structures, fire-resistant insulations and a method for fire-proofing and fire-protection of permanent or temporary structures or objects. The fire-resistant insulation withstands temperatures between 1200° C. and 2000° C. on the exterior side of the insulation, and the interior side provides a shield for fire-protected structure or object against temperatures not exceeding 300° C. A method for fire-protection comprises steps of providing a fire-protection for structures and objects subjected to fires, brush-fires or fire storms.
Claims21
A fire-resistant structure or object protected with a fire-resistant insulation having a thermo-insulating gradient, said insulation comprising of a one-ply or two-ply blanket or sheath insulation capable of withstanding temperatures above 1200° C. for more than fifteen minutes, wherein said insulation covers said structure, is built into said structure or is attached to said structure,
- wherein said insulation is a one-ply or two-ply blanket insulation with each ply comprising an exterior layer, an intermediary layer and an interior layer,
- wherein said exterior layer is positioned at an outermost exterior side of the insulation and is made of one or a plurality of sheets of a material selected from the group consisting of silica, aluminoborosilicate, silicon carbide fabric, aluminized film, aluminized foil or organometallic polymer and wherein said exterior layer is capable of withstanding temperature from about 1200° C. to up to about 2000° C.;
- wherein said interior layer is positioned at an innermost backside of the insulation facing said structure or object and is made of one or plurality of sheets of a material selected from the group consisting of silicon carbide fabric, scrim fabric containing aluminoborosilicate, scrim fabric containing silica, felt containing silica, felt containing alumina, felt containing aluminoborosilicate, polyimide film, polyvinyl fluoride film, polyether ketone film, polyimide film containing gold, polyimide film aluminized on one or both sides, aluminized film, aluminized foil, organometallic polymer, mat containing silica and mat containing aluminoborosilicate and wherein said interior layer is capable of protecting said structure or object from reaching temperatures over about 300° C.;
- wherein said intermediary layer is positioned between said exterior and said interior layers and comprises a plurality of flat or honeycomb sheets of the same or different material selected from the group consisting of silica, aluminoborosilicate, silicon carbide fabric, aluminized film, aluminized foil, organometallic polymer and polyimide film aluminized on one or both sides;
- and
- wherein said insulation comprising said three layers has the thermo-insulating gradient where at the exterior layer, said fire-resistant insulation has a fire-resistance capability to withstand fire having temperatures above 1200° C. and up to about 2000° C., and at the interior layer facing a structure or object to be fire-protected, said fire-resistant insulation has a capability to maintain and provide a shield for temperatures not exceeding 300° C. in said structure or object.
