Description
技术领域
本发明涉及保温材料技术领域，具体涉及一种酚醛树脂保温材料及其制备方法。
背景技术
酚醛树脂是苯酚和甲醛缩聚而成，其发泡物。酚醛树脂经过发泡固化后，基本没有有害物质。酚醛泡沫材料属高分子有机硬质铝箔泡沫产品，是由热固性酚醛树脂发泡而成，它具有轻质、防火、遇明火不燃烧、无烟、无毒、无滴落，使用温度围广(-196～+200℃)低温环境下不收缩、不脆化，是暖通制冷工程理想的绝热材料，由于酚醛泡沫闭孔率高，则导热系数低，隔热性能好，并具有抗水性和水蒸气渗透性，是理想的保温节能材料。
酚醛树脂保温材料可以有效解决建筑防火保温问题，在高温下不熔滴、不软化、发烟量低，不扩散火焰，耐火焰穿透，防火性能出色，并且具有良好的保温节能效果，将优异的防火性能与良好的节能效果集于一身，适合于外墙外保温；也可以与饰面层复合制作保温装饰一体化板，还可以用于构筑传统EPS/XPS/PU外墙保温***防火隔离带，用作幕墙内的防火保温隔热材料、防火门内隔热材料，以及低温或高温场合的防火保温隔热材料。尽管在保温性、防火性等方面具有以上优势，但目前常规酚醛树脂保温材料的物理性能不是很好，尤其是粘结性不好，因此只能用于特定的保温工程当中；而且，常规酚醛树脂保温材料质地较脆，容易粉化抗压抗折能力差，因而极大限制了此类材料在建筑保温中的应用。
发明内容
本发明旨在针对现有技术的技术缺陷，提供一种酚醛树脂保温材料及其制备方法，以解决常规酚醛树脂保温材料物理性能有待改善的技术问题。
为实现以上技术目的，本发明采用以下技术方案：
一种酚醛树脂保温材料，包括以下重量份的成分：酚醛树脂80～95份，聚硅氧烷交联剂2～8份，二苯甲烷二异氰酸酯4～8份，有机硅油1～5份，三羟甲基丙烷1～3份，十溴二苯乙烷1～5份，正庚烷2～8份，发泡剂0.5～1份，阻燃剂0.5～1.5份，催化剂0.2～0.8份，固化剂0.1～0.3份，稳定剂0.5～0.8份。
作为优选，所述发泡剂为环氧乙烷或溴代异丁烷。
作为优选，所述阻燃剂为三聚磷酸铝或三聚氰胺氰尿酸盐。
作为优选，所述催化剂为二铵己二酸，三氟乙酰乙酸乙酯或1,6-己二胺盐酸盐。
作为优选，所述固化剂为脂环胺类固化剂或聚琉醇类固化剂。
作为优选，所述稳定剂为聚磷酸铵或钛酸正丁酯。
在以上技术方案的基础上，本发明进一步提供了上述酚醛树脂保温材料对的制备方法，包括以下步骤：
1)向反应容器中加入氯化钴和硫酸锌，以氮气置换反应容器中的空气，而后在80℃条件下保持20min，向其中加入苯酚，甲醛和盐酸，以120～160℃的温度2～3.5Mpa的压力反应10～20min，而后恢复至常压，再向其中加入2-溴异丁酸叔丁酯继续反应5～10min；
2)收集步骤1)所得产物，在4～6℃环境中保持20min，向其中加入硫酸锌，在搅拌状态下降温至0～1℃，收集析出的固体，清洗后以30～40℃的温度减压干燥，即得到酚醛树脂；
3)取配方量的步骤2)所得的酚醛树脂，在氮气保护下升温至120～130℃直至熔融，而后向其中加入配方量的聚硅氧烷交联剂，二苯甲烷二异氰酸酯，有机硅油，三羟甲基丙烷，十溴二苯乙烷，搅拌使其溶解，降温至100～110℃，再向其中加入配方量的正庚烷，发泡剂，阻燃剂，催化剂，固化剂，稳定剂，过程中保持搅拌且超声震荡状态，而后将体系温度以不高于0.5℃/min的温度降温至常温，即得到所述酚醛树脂保温材料。
作为优选，步骤1)中氯化钴，硫酸锌，苯酚三者的摩尔比为1:0.3:0.875。
作为优选，步骤2)中清洗的水温为30～50℃。
作为优选，步骤3)中超声震荡的频率为20～40KHz。
