Polymer-based detachable coatings are used to protect industrial products and military equipment from surface damage and contamination during manufacturing and transportation. To expand their application to various industrial fields, it is essential to simultaneously implement diverse characteristics, such as low glass transition temperature, high detachability and uniformity, and high flame retardancy. In this study, we prepared Mg(OH)₂/silica composite aerogel, which was used to prepare a detachable poly(vinyl butyral) coating solution to improve the flame retardancy and reduce the glass transition temperature of the coating. Furthermore, we investigated the effect of the addition of a surfactant for achieving a detachable coating with good uniformity and flame retardancy. The coating prepared using the Mg(OH)₂/silica composite aerogel and nonionic surfactant exhibited a surface area of 496 m²/g. In addition, the coating maintained its flexibility even at sub-zero temperature (−7 °C) and exhibited significantly improved flame retardancy as it withstood fire for more than 15 s before igniting compared to the original coating.

聚合物基可分离涂层用于保护工业产品和军事设备在制造和运输过程中免受表面损坏和污染。为了将其应用扩展到各种工业领域，必须同时实现多种特性，例如低玻璃化转变温度、高可分离性和均匀性以及高阻燃性。在本研究中，我们制备了 Mg(OH) ₂/二氧化硅复合气凝胶，用于制备可分离的聚乙烯醇缩丁醛涂料溶液，以提高阻燃性，降低涂料的玻璃化转变温度。此外，我们研究了添加表面活性剂对获得具有良好均匀性和阻燃性的可分离涂层的影响。使用Mg(OH) ₂ /二氧化硅复合气凝胶和非离子表面活性剂制备的涂层具有496 m ² /g的表面积。此外，该涂层即使在零下温度（-7 °C）下也能保持其柔韧性，并且与原始涂层相比，在点燃前耐火超过 15 秒，因此阻燃性显着提高。
