Description

一种阻燃隔热的聚氯乙烯泡沫材料及其制备方法
技术领域
本发明属于泡沫材料技术领域,具体涉及一种阻燃隔热的聚氯乙烯泡沫材料及其制备方法。
背景技术
聚氯乙烯(PVC)泡沫材料由于具有较宽的使用温度和良好的耐腐蚀性能,被广泛应用于建筑、建材、装饰、家具、广告、汽车等行业。现有技术中,硬质聚氯乙烯交联泡沫材料的组分主要包括聚氯乙烯树脂、发泡剂(如偶氮二异丁腈和偶氮二甲酰胺)、异氰酸酯(如甲苯二异氰酸酯、碳化二亚胺——脲酮亚胺改性4,4‘-二苯基甲烷二异氰酸酯)和酸酐(如马来酸酐、邻苯二甲酸酐)。其制备方法是:先将固体物料和液体物料混合得到糊状物料,然后将糊状物料倒入模具中,在压力下升高温度,使模具内部糊状物料温度达到150-200℃,此时PVC树脂发生凝胶,发泡剂分解,模压时间控制为50-60s/mm,降温后开模,得到含有许多微小气泡的预发泡体,最后将预发泡体置于热水或者蒸汽中,加热完成二次膨胀,同时扩散进预发泡体内的水分会和异氰酸酯与酸酐发生一系列反应,产生二氧化碳气体并在泡沫体中形成交联结构,固化得到硬质泡沫。
当聚氯乙烯泡沫材料应用到阻燃领域时,需要进行阻燃改性,现有技术中,阻燃改性聚氯乙烯泡沫材料的方法主要是在聚氯乙烯泡沫材料中添加阻燃剂,如中国专利一种改性硬质交联聚氯乙烯阻燃泡沫及其制备方法(公开号104031326A),采用添加磷酸酯或含溴阻燃剂的方案将聚氯乙烯泡沫材料阻燃提高到B1级。
但是,现有技术中,聚氯乙烯泡沫材料添加的阻燃剂多为有机小分子物质,添加量较多,不利于降低泡沫材料的导热系数,导致泡沫材料的隔热性能和耐热性能较差的问题。

优选的,所述表面活性剂为吐温80、聚硅氧烷接枝聚醚化合物(DC-193)中的一种或两种。
优选的,所述石墨粉为400-2000目,更优选的为800-1500目。
优选的,还包括10-20重量份的填料,更优选,所述填料为碳酸钙和/或滑石粉。
优选的,所述聚氯乙烯树脂为悬浮树脂和/或糊树脂。
上述阻燃隔热的聚氯乙烯泡沫材料的制备方法,步骤如下:
步骤一、按组成及重量份称取各组分,混合均匀后,加入模具中,先在50~110℃预热5~30min,然后升压至11MPa~30MPa,升温至150℃~200℃,模压时间30-50s/mm,最后冷却至20℃~110℃后开模,得到发泡模压物;
步骤二、在水或水蒸气中,将得到的发泡模压物进行二次发泡和固化,得到阻燃隔热的聚氯乙烯泡沫材料。
优选的,步骤一中,升压至15MPa~25MPa,升温至180℃~200℃。
