用于形成舒适度增加的聚氨酯制品的树脂组合物
摘要：
一种具有末端环氧乙烷端段的亲水性多元醇(A)和疏水性多元醇(B)的特有结合物用于树脂组合物和聚氨酯体系中，并用以形成聚氨酯制品，如聚氨酯泡沫。所述亲水性多元醇(A)富含环氧乙烷(EO)，所述疏水性多元醇(B)富含环氧丙烷(PO)。所述亲水性多元醇(A)和所述疏水性多元醇(B)以1.5∶1至20∶1的重量比(A∶B)存在于树脂组合物和聚氨酯体系中。由于相对于之前的聚氨酯制品具有降低的共振频率和降低的峰值振动传递率，所述聚氨酯制品在车辆应用、如汽车和摩托车座椅的使用中表现出极好的舒适度。
摘要（英）：

A unique combination ofa hydrophilic polyol (A) and a hydrophobic polyol (B) having a terminal ethylene oxide cap are used in a resin composition and a polyurethane system, and are used to form a polyurethane article, such as a polyurethane foam. The hydrophilic polyol (A) is ethylene oxide (EO) rich and the hydrophobic polyol (B) is propylene oxide (PO) rich. The hydrophilic polyol (A) and the hydrophobic polyol (B) are present in the resin composition and the polyurethane system in a weight ratio (A:B) of from 1.5:1 to 20:1. The polyurethane article exhibits excellent comfort for use in vehicle applications, such as automotive and motorcycle seating, due to reduced resonance frequency and reduced peak vibration transmissivity relative to previous polyurethane articles.
