阅读说明：本技术 对苯二甲酸酯多元醇和烃发泡剂的相容共混物 (Compatible blends of terephthalate polyols and hydrocarbon blowing agents ) 是由 F·拉泰拉 G·瓦罗 L·波图塞利 于 2020-04-20 设计创作，主要内容包括：调配型多元醇组合物含有基于对苯二甲酸的聚酯多元醇、C4-7烃发泡剂以及亲水亲脂平衡大于13到18.5的非离子型表面活性剂。所述调配型多元醇组合物表现出极好的储存稳定性并且抵抗分层。所述组合物可用于制作硬质聚氨酯和/或聚异氰脲酸酯泡沫。所述发泡剂的良好相容性使所述泡沫中的泡孔结构得到改进。(The formulated polyol composition contains a terephthalic acid-based polyester polyol, a C4-7 hydrocarbon blowing agent, and a nonionic surfactant having a hydrophilic-lipophilic balance of greater than 13 to 18.5. The formulated polyol composition exhibits excellent storage stability and resists delamination. The compositions are useful for making rigid polyurethane and/or polyisocyanurate foams. The good compatibility of the blowing agent leads to an improved cell structure in the foam.)
