本文综述了膨胀型阻燃剂在防火自动窗帘中的填充作用。制备了几种膨胀组合物，当它们暴露于高温时形成隔热烧焦层，并将其施加到帘的矿物织物基底上。防火性能的生产材料进行了评估，并与国外标本进行了比较。膨胀系数和材料的耐火极限被认为是操作参数。在防火测试中表现最好的开发样本被送往认可的实验室。它被证明，使用标准化的方法，它的耐火极限达到30分钟。这证明了膨胀化合物的有效贡献，并开辟了在防火窗帘制造中使用它们的新方法。
The paper overviews the way by which intumescent fire retardant compositions act as fillers in fire-resistant automatic curtains. A several intumescent compositions, which form a heat-isolating charred layer when they are exposed to high temperatures, were produced and applied to the mineral-fabric basis of the curtain. Fire-protective properties of produced materials were assessed and compared with foreign specimens. Swelling coefficient and material's fire durability were considered as operating parameters. The developed specimen which performed the best during fire tests was sent to accredited laboratory. It was proven, using standardized methods, that it's fire resistance limit reaches 30 minutes. This proves an effective contribution of an intumescent compound and opens new ways of using them in fire curtains manufacturing.
