Description

一种应用于太阳能热水器的聚氨酯泡沫塑料
技术领域
本发明涉及泡沫塑料技术领域,具体涉及一种应用于太阳能热水器的聚氨酯泡沫塑料。
背景技术
聚氨酯泡沫塑料是异氰酸酯和羟基化合物经聚合发泡制成,按其硬度可分为软质和硬质两类。业界所知,聚氨酯硬质泡沫塑料被广泛应用于热水器、冷柜、管道和建筑等场合,起隔热保温阻音的作用,而聚氨酯硬质泡沫塑料是由聚氨酯硬质泡沫组合料与异氰酸酯反应所得到的,人们还习惯将聚氨酯硬质泡沫塑料称为聚氨酯泡沫塑料或高分子合成材料。已有技术中的硬质泡沫塑料所存在的最大缺憾是平均芯密度高,在35~40Kg/m3,而平均芯密度高会进而引发以下三个方面的不足:一是造成用于生产泡沫塑料的原料如聚氨酯硬质泡沫组合料和异氰酸酯的耗用量大,不仅不合理地造成原料浪费,而且导致成本的无为增加;二是平均芯密度高会产生导热系数高,从而使发泡后的泡沫体的保温性能差,电能浪费严重;三是由于平均芯密度高,在对泡沫塑料产品生产时造成脱模时间长的问题,影响生产效率,使产能受到制约。
公开号为CN105524246A的专利申请,公开了一种无卤阻燃生物基聚氨酯硬质泡沫塑料及其制备方法,该聚氨酯硬质泡沫塑料配方按重量计各组分为:魔芋飞粉多元醇100份,含P-N超支化有机硅改性石墨烯1~6份,多异氰酸酯100~180份,水5~30份,泡沫稳定剂1~5份,胺类催化剂0.1~3份,锡类催化剂0.1~3份。该种泡沫塑料具有良好的阻燃性能和力学强度,但是其水蒸气渗透系数较高,应用于太阳能热水器中难以符合要求。
公开号为CN102617821A的专利申请,公开了一种以稻壳为原料的聚氨酯泡沫塑料及其制备方法,所述泡沫塑料配方包括:稻壳100~190份、异氰酸酯100~150份、扩链交联剂0.5~5份、泡沫稳定剂2~5份、催化剂0.01~3份、发泡剂0~10份。所述泡沫塑料的制备方法包括步骤:将稻壳粉先与聚乙二醇、乙二醇与丙三醇制成稻壳液化物,再加入扩链交联剂、催化剂、泡沫稳定剂、异氰酸酯,混合均匀后进行模具浇注,密封,熟化,冷却脱模,得到所需。本发明用稻壳制备聚氨酯泡沫塑料,提高了稻壳的利用率,降低了聚氨酯泡沫的制作成本;该种聚氨酯泡沫塑料具有较好的缓冲吸能性能和保温隔热性能,但是其压缩强度较差,应用于太阳能热水器中难以符合要求。
