摘　　要：通过对泡沫稳定剂和国产聚醚的筛选 ,研制的HY5 10 6环戊烷组合聚醚具有不分层、流动性优良及泡孔细腻等特点。它用于冰箱的保温层 ,其泡沫的主要性能指标为 :平均芯密度35 .6kg/m3,最大芯密度差 1.6kg/m3,10 %压缩强度 170kPa ,导热系数 0 .0 191W/ (m·K) ,低温尺寸稳定性 0 .2 1%。结果表明 ,HY5 10A cyclopentane blown polyurethane foam system has been developed, and successfully applied in the refrigerator production with good flowability. The maximum difference of the core density distribution is only 1.6 kg/m 3. The foam achieved compressive strength (10% deflection) of 170 kPa, thermal conductivity of 0.0191W/(m·K), dimensional stability of 0.21%, at core density of 35.6 kg/m 3.The result shows that this system meet the production and property requirement of appliance application.
