A novel fireproof curtain comprises a fireproof curtain body, and the fireproof curtain body is composed of an inner layer, a middle layer and an outer layer which are sequentially arranged in an overlapped mode; the inner layer is composed of at least one of a polyether-ether-ketone layer, a polyphenylene sulfide layer, a polytetrafluoroethylene layer or a PFA layer; the middle layer is composedof at least one of a heat-resistant metal plate layer, a carbon fiber layer, a graphite layer, a high-temperature-resistant fiber fabric layer or a high-temperature-resistant coating fabric layer; theouter layer is composed of at least one of a silicone rubber coated fabric layer and a high-temperature-resistant composite fabric layer. The novel fireproof curtain has the beneficial effects that the novel fireproof curtain effectively overcomes the defects that a large amount of spark deposited carbon is accumulated on the fireproof curtain, and the service life of the fireproof curtain is shortened. By using the fireproof curtain provided by the invention, when the spark deposited carbon is attached to the inner layer of the fireproof curtain to reach a certain volume and weight (the density reaches 3.53 g/cm<3>), the spark deposited carbon can automatically fall off along with the increase of dead weight and the impact of subsequent sparks.
本申请公开了一种新型防火帘，包括防火帘本体，所述防火帘本体由依次重叠设置的内层、中间层和外层组成；所述内层由聚醚醚酮层、聚亚苯基硫醚层、聚四氟乙烯层或PFA层的至少一层组成；所述中间层由耐热金属板层、碳纤维层、石墨层、耐高温纤维织物层或耐高温涂覆织物层的至少一层组成；所述外层由硅橡胶涂覆织物层、耐高温复合织物层的至少一层组成；本发明的有益效果为：本发明所述一种新型防火帘有效地解决了火花积碳在防火帘上大量堆积，降低防火帘使用寿命的弊端；使用本发明所述防火帘，当火花积碳在防火帘内层附着达到一定的体积和重量时(密度达到3.53g/cm3)，火花积碳会随着自重的增加及后续火花的冲击自行脱落。
