摘要
针对北方地区冬季防腐保温施工不方便的缺憾 ,研制开发出了一种低粘度的聚氨酯用聚醚多元醇 ,使改进后的聚氨酯制品体系粘度明显降低 ,流动性得以改善 ,提高了硬质泡沫制品强度和尺寸稳定性 ,既满足了原有指标的要求 ,又给施工带来了方便 ,在 -1 5℃以下环境施工过程中 ,解决了酥皮、脆裂等问题 。
A kind of low viscosity polyether polyol which is suitable to rigid polyurethane foam in winter is developed and manufactured. The foam is made with low thermal conductivity, excellent physical characters and dimensional stability.
