A method for producing a polyurethane foam having a density of 0.1 g/cm3 or more, including the step of reacting a polyol component and a polyisocyanate component, the polyol component containing (polyol A): a polyester-polyol having a hydroxyl value of from 45 to 115 mgKOH/g, obtained by polycondensing a polyhydric alcohol component containing a polyhydric alcohol having a side chain and a polybasic acid component; and (polyol B): a polyether-polyol having 3 functional groups and a hydroxyl value of from 15 to 40 mgKOH/g, wherein the weight ratio of the polyol A to the polyol B, i.e. polyol A/polyol B, is from 1.2 to 3. The polyurethane foam obtained according to the method of the present invention can be suitably used, for example, in shoe soles, cushioning materials for automobiles and other transportation vehicles, furniture, beddings, and the like.
一种生产密度为 0.1 g/cm3 或更高的聚氨酯泡沫的方法,包括使多元醇组分和多异氰酸酯组分反应的步骤,该多元醇组分包含 (多元醇 A):羟基值为 45 至 115 mgKOH/g 的聚酯多元醇,由包含具有侧链的多元醇和多基酸组分的多元醇组分缩聚而得;以及 (多元醇 B):具有 3 个官能团且羟基值在 15 至 40 mgKOH/g 之间的聚醚多元醇,其中多元醇 A 与多元醇 B 的重量比,即多元醇/多元醇 B 的重量比,为 1:1。根据本发明方法得到的聚氨酯泡沫可适当用于鞋底、汽车和其他运输工具的缓冲材料、家具、床上用品等。
