Research on polymer cement fireproof coiled material A Dissertation Submitted for the Degree of Master Candidate ：Cui Bo Supervisor：Prof. Liu Kaiping Chang’an University， Xi’an ， China 摘 要 当前，我国外墙有机保温材料普遍易燃，存在安全隐患，一旦起火，其火势蔓延快， 救火时间少，经济损失严重。因此，增强外墙有机材料的阻燃性，对降低火灾风险，减 少经济损失有重要意义。本文从这一问题出发，采用聚合物对水泥砂浆进行改性，同时 添加一定量的阻燃剂、外加剂，将其涂刷在无纺布的外表层制成聚合物水泥防火卷材， 并且使其具有合适的阻燃性，耐水性及柔韧性。将聚合物水泥防火卷材在有机保温材料 生产时同步加工在其附面层以达到提高外墙有机保温材料阻燃性的目的。以聚合物改性 水泥为技术基础，对其应用于阻燃防火材料进行尝试，拓宽聚合物改性材料在工程上的 应用范围。 本文以聚合物为主要因素对水泥防火卷材的性能进行研究。研究的内容主要包括： 不同种类聚合物乳液对水泥防火卷材性能的影响，不同种类阻燃剂对水泥防火卷材性能 的影响，不同种类水泥对防火卷材的性能影响,以及聚合物水泥防火卷材各原料配比对 其性能的影响。 研究结果表明:聚合物乳液对水泥卷材性能起重要作用。氢氧化铝作为卷材阻燃剂 性能优于氢氧化镁，硅酸盐水泥较铝酸盐水泥更适于制作防火卷材。通过正交试验，确 定了聚合物水泥防火卷材的最优配比。 关键词：VAE；丙烯酸乳液；防火卷材；建筑保温；阻燃 Abstract At present, Chinas external walls of organic insulation materials generally flammable, there are security risks, once ignited, the fire spread quickly, less time fire-fighting, and serious economic losses. Therefore, improving the external walls of flame retardant properties of the organic material, is important to reduce the risk of fire and reduce economic losses. In this paper, starting from this issue, we use polymer modified cement mortar, while adding a certain amount of fire retardants, additives, then brush them on the outer surface of the nonwoven fabric to made the polymer cement fireproof coiled material. The polymer cement fireproof coiled material added an organic insulation material in the wall surface, to improve the flame retardancy. Polymer modified cement foundation to try its used in fire retardant materials. Broaden the range of applications of polymer modified materials in engineering. In this paper, polymer as the main factor, to study the
