发明名称 Fire-resistant polyurethane foam
摘要 A fire-resistant polyurethane foam is provided. A hydroxyl-containing inorganic fire retardant is premixed with a polyisocyanate and a polyol, respectively, to form two premixtures. Then, the two premixtures are mixed for reaction to form a fire-resistant polyurethane foam. Preferably, a combination of different particle sizes of the fire retardant is employed to maximize the amount of the fire retardant and increase the fire resistance of the foam.

主权项 1. A fire-resistant polyurethane foam, comprising a polyurethane; and about 50-80 wt % of a hydroxyl-containing inorganic fire retardant, based on the weight of the fire-resistant polyurethane foam, wherein the hydroxyl-containing inorganic fire retardant reacts with the polyurethane to form a chemical bond, wherein the fire-resistant polyurethane foam has a density of about 0.05-0.7 g/cm3, wherein the hydroxyl-containing inorganic fire retardant comprises particle sizes of 0.5-5 μm, 5-20 μm, and 20-100 μm in a weight ratio of 1:0.1-2:0.1-2.
