Description

一种聚氨酯高强复合隔热板的制备方法
技术领域
本发明涉及材料合成方法,具体的是一种聚氨酯高强复合隔热板的制备方法。
背景技术
中空玻璃微球(HGM)主要从粉煤燃烧后的粉煤灰中提取出的和人工合成的,原料来源广泛、价格低廉。HGM具有诸多优良的性能,包括质轻、导热系数低和抗压能力强等。HGM在复合材料中广泛应用,不仅可以降低复合材料的密度,而且还可以增加复合材料的力学性能、绝缘性和耐热性等性能。
陈伟红等通过HGM 对PU泡沫燃烧和力学性能的影响的实验表明,PU泡沫中仅加入 HGM对其氧指数和水平燃烧速度影响不大,但可改变其应力-应变过程:当压力低于临界值时,应变随压力增大而缓慢增加;而当压力超过临界值后,应变随压力增大而迅速增加。Bian等通过向硬质PU泡沫塑料中添加石墨和HGM,实验表明:10%(wt,质量分数,下同)的HGM、20%的石墨和70%的硬质泡沫塑料制得的复合材料具有最佳的阻燃性能,且复合材料的极限氧指数达到了30%(体积比),并得到了最大耐压强度和弹性模量。Im等研究表明,随着HGM的含量增加,复合材料的拉伸强度增加,而其密度和溶胀比下降。Yakushin等研究了密度为125kg/m3的HGM对低密度(54~90kg/m3)硬质泡沫塑料的性能影响,在微球含量为0.5%~5%的范围内确定微球含量对该泡沫塑料热膨胀系数、拉伸和压缩性能的影响。其结果表明:微球含量为1%~2%范围内,含量增加压缩性能增加,含量继续增加,压缩性能下降。PU泡沫体的密度为90 kg/m3时,随着微球含量增加,泡沫塑料的强度和弹性模量增加;密度为54kg/m3时,趋势恰恰相反。
发明内容
本发明所要解决的技术问题在于提供一种聚氨酯高强复合隔热板的制备方法,提供一种新的合成方法。
本发明采用的制备方法,包括如下步骤:
a、将含有水分的PPG-1000加入四口瓶中抽真空加热,在温度为100-105℃时脱水1-1.75h,然后冷却回收备用;
b、向纸杯中分别加入25%(wt,质量分数,下同)的PAPI、12.5% 的a步骤制得的PPG-1000和0.5%的液体醋酸苯汞,混合均匀制得预聚体;
c、复合材料的制备,向预聚体中加入62% 的HGM混合均匀,倒入已凃脱模剂的模具中,加压加热固化2.5-2.75h,然后在干燥箱中后固化,即得。
本发明的有益效果是:制备的PU/HGM复合材料可潜在用于导弹发射车的隔热材料以及工业生产的热解反应器、电厂通风口的保温材料等领域,具有较好的市场前景。
具体实施方式
以下结合实例进一步说明本发明的内容,由技术常识可知,本发明也可通过其它的不脱离本发明技术特征的方案来描述,因此所有在本发明范围内或等同本发明范围内的改变均被本发明包含。
实施例1:
a、将含有水分的PPG-1000加入四口瓶中抽真空加热,在温度为105℃时脱水1.75h,然后冷却回收备用;
b、向纸杯中分别加入25%(wt,质量分数,下同)的PAPI、12.5% 的a步骤制得的PPG-1000和0.5%的液体醋酸苯汞,混合均匀制得预聚体;
c、复合材料的制备,向预聚体中加入62% 的HGM混合均匀,倒入已凃脱模剂的模具中,加压加热固化2.5h,然后在干燥箱中后固化,即得。
实施例2:
a、将含有水分的PPG-1000加入四口瓶中抽真空加热,在温度为105℃时脱水1.75h,然后冷却回收备用;
b、向纸杯中分别加入25%(wt,质量分数,下同)的PAPI、12.5% 的a步骤制得的PPG-1000和0.5%的液体醋酸苯汞,混合均匀制得预聚体;
c、复合材料的制备,向预聚体中加入62% 的HGM混合均匀,倒入已凃脱模剂的模具中,加压加热固化2.75h,然后在干燥箱中后固化,即得。
通过实验得出力学性能:压缩强度为37.95-38.58MPa,弹性模量为9.96 MPa,最大压缩应变5.25-5.52%;硬度值为73-75(邵氏-D);热性能:导热系数为 0.1455-0.1485W/m·K,耐热性(使用温度)为220℃左右,300℃时失重率为80%。
可以看出制备的PU/HGM复合材料可潜在用于导弹发射车的隔热材料以及工业生产的热解反应器、电厂通风口的保温材料等领域,具有较好的市场前景。
