Description
技术领域
本发明涉及建材装修技术领域,具体的涉及一种防火玻璃纤维装饰毡及其制备方法。
背景技术
装饰建材的防火原理不仅在于燃烧时其可以吸收大部分热源热量,同时也要求材料在受到火的燃烧作用时,尽可能长时间的保持整体结构的完整性。现如今市场普通合成纤维薄毡及高分子防火材料遇明火燃烧时会释放可燃气体和其他有毒气体,且当其内的结晶水蒸发完后,毡就变酥变脆,最终破裂,使火焰穿透毡面,对建筑结构失去保护作用,限制了其应用。本发明中防火玻璃纤维装饰毡所用的面层材料是玻璃纤维,在干燥固化过程中,随着玻纤薄毡中水分的蒸发,粘结剂逐步渗透到面层,并与玻璃纤维牢固的粘合在一起。干燥后的薄毡遇火后,玻璃纤维本身具有一定的阻燃性,且玻纤薄毡内的粘结剂被燃烧炭化后阻燃,使薄毡中的纤维部分仍牢固地结合为整体,支撑着薄毡使其不被破坏。
