Abstract
A water-permeable and fire-resistant film and the preparing method thereof is disclosed. The water-permeable and fire-resistant film comprises polyurethane resin; a first fire-resistant agent; a second fire-resistant agent, an inorganic fire-resistant agent and an additive agent. The first fire-resistant agent used is selected from the group consisting of paraffine chlorinated, decabromodiphenyI oxide, hexachloro benzene, hexabromo benzene, pentabromo ethyl benzene, pentabromo diphenyl oxide and octabromo diphenyl ether. The second fire-resistant agent used is selected from the group consisting of Sb2O3 and Sb2OS. The surface of the film produced is smooth.
