生物基阻燃聚酯多元醇聚氨酯硬泡在煤矿中的应用

用生物基阻燃聚酯多元醇替代石油基聚醚多元醇添加于聚氨酯硬泡组合聚醚中,研究了该生物基阻燃聚酯多元醇的替代量,以及在煤矿中阻燃效果。结果表明,生物基聚酯多元醇可替代部分石油基聚醚多元醇使用,当生物基聚酯多元醇在总聚醚多元醇体系中占40%~50%时,聚氨酯泡沫的压缩强度高、尺寸稳定性良好、导热系数低且阻燃效果理想,达到中华人民共和国煤炭行业MT-113—1995标准,保证了煤矿安全使用。

Application of Biological Basis Flame Retardant Polyester Polyol for Rigid Polyurethane Foams in Coal Mine

Using the biological basis flame retardant polyester polyols substitute for oil based polyether polyols for rigid polyurethane foam. The substitute amount of biological basis polyester polyol in total polyesther polyol and the effect of flame retardant in the coal mine were researched. The results showed that the polyurethane foam had high compressive strength, good dimensional stability, low thermal conductivity and perfect flame retardant effect when the mass fraction of biological basis polyester polyols was 40% - 50% in total polyether. The foam index aco- orded with the People＇s Republic of China Coal Industry Standard MT-113--1995. The product safely use in coal mine was guaranteed.
