Abstract
A composite product includes gypsum in an amount of 70 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert.
Claims18
A fire resistant composite product comprising:
- a composite comprising gypsum in an amount sufficient to provide fire resistance wherein the amount is 60 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight;
- wherein the fibers comprise glass fibers, cellulose fibers, polyvinyl alcohol fibers and polypropylene fibers;
- the composite is caused or allowed to cure to form a cured composite;
- and
- the cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel, wherein the fire resistant component is selected from a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, and a door insert.
A fire resistant composite product comprising:
- a composite consisting of gypsum in an amount sufficient to provide fire resistance wherein the amount is 60 to 85% by weight, fibers in an amount of 1.5 to 5% by weight substantially homogeneously distributed through the composite, an aggregate in an amount of 10 to 25% by weight substantially homogeneously distributed through the composite, a starch in an amount of 2 to 7% by weight, a rheology-modifying agent in an amount of 0.5 to 4% by weight, and optionally a vermiculite or clay in an amount of 0 to 10% by weight;
- the composite is caused or allowed to cure to form a cured composite;
- and
- the cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel, wherein the fire resistant component is selected from a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, and a door insert.
A fire resistant composite product comprising:
- a composite comprising gypsum in an amount sufficient to provide fire resistance wherein the amount is 70 to 90% by weight, glass fibers in an amount of 2 to 10% by weight substantially homogeneously distributed through the composite, cellulose fibers in an amount of 2 to 8% by weight substantially homogeneously distributed through the composite, polyvinyl alcohol fibers in an amount of 1 to 4% by weight substantially homogeneously distributed through the composite, polypropylene fibers in an amount of 0.3 to 4% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight;
- the composite is caused or allowed to cure to form a cured composite;
- and
- the cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel, wherein the fire resistant component is selected from a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, and a door insert.
