The development of fire prevention and mitigation technologies with a benign toxicological and environmental profile has become of particular interest in the USA due to the recent adoption of state regulations that severely restrict the use of flame retardants in certain products, like residential upholstered furniture (RUF). Herein, the effectiveness of a backcoating technology in RUF is demonstrated. The backcoating is a silicone-based elastomer, filled with vinyl-silane modified aluminum-hydroxide that was applied to the back side of an upholstery fabric to generate a flexible and effective fire barrier. Chair mock-ups were assembled using either an uncoated cotton fabric (UCF) or a backcoated cotton fabric (BCF) as cover fabric. The fire performance of the chair mock-ups incorporating the UCF and BCF was compared in an open-burning calorimeter after exposure to either a flaming ignition source or a smoldering ignition source. In the flaming ignition tests, the chair mock-ups with BCF showed a reduction in the peak heat release rate and the total heat released by factors of about 6 and 45, respectively, as compared to the chair mock-ups with UCF. In the smoldering ignition tests, the chair mock-ups with UCF showed intense smoldering, which eventually transitioned to open flaming, whereas, the BCF chair mock-ups showed no sign of foam or fabric smoldering. The backcoating also offered a durable fire protection solution, with an abrasion resistance of BCF roughly doubled compared to UCF. Ultimately, the backcoating provided an unusual combination of smoldering and flaming ignition resistance while complying with several recently enacted or pending U.S. state regulations.

展示防火软垫家具的一体化解决方案：用于阴燃和阻燃覆盖织物的良性背涂层

由于最近通过的州法规严格限制在某些产品（如住宅软垫家具 (RUF) . 在此，证明了背涂技术在 RUF 中的有效性。背涂层是一种硅基弹性体，填充有乙烯基硅烷改性的氢氧化铝，应用于室内装潢织物的背面，以产生灵活有效的防火屏障。使用未涂层棉织物 (UCF) 或背面涂层棉织物 (BCF) 作为覆盖织物组装椅子模型。在暴露于燃烧点火源或阴燃点火源后，在开放式燃烧​​量热计中比较了包含 UCF 和 BCF 的椅子模型的防火性能。在燃烧测试中，与带有 UCF 的椅子模型相比，带有 BCF 的椅子模型显示峰值热释放率和释放的总热量分别降低了约 6 和 45 倍。在阴燃点火测试中，带有 UCF 的椅子模型显示出强烈的阴燃，最终转变为明火，而 BCF 椅子模型没有显示泡沫或织物阴燃的迹象。背涂层还提供了一种耐用的防火解决方案，与 UCF 相比，BCF 的耐磨性大约翻了一番。最终，
