分析了不同菜籽油多元醇含量的水吹硬质聚氨酯泡沫的发泡过程。本工作报告了泡沫鉴定系统foamat对发泡过程的分析，该系统可以记录发泡过程中的介电极化、样品上升高度、压力、温度等特征参数。用菜籽油基多元醇（ROP）替代石化多元醇会降低体系的反应性，从而影响硬质聚氨酯泡沫的发泡过程。随着ROP含量的增加，介质极化的减小幅度较小，反映了较慢的胶凝和发泡反应。(C) 2016 Elsevier B.V.版权所有
The foaming process of water-blown rigid polyurethane foams with different contents of a rapeseed oil based polyol was analyzed. The present work reports for an analysis of the foaming process using foam qualification system FOAMAT-which allows recording characteristic parameters such as the dielectric polarization, rise height of a sample, pressure, temperature during a foaming process. A replacement of a petrochemical polyol by a rapeseed oil-based polyol (ROP) affects the foaming process of rigid polyurethane foams by reducing the reactivity of the system. Increasing the content of ROP resulted in a smaller decrease in the dielectric polarization which reflects slower gelling and foaming reactions. (C) 2016 Elsevier B.V. All rights reserved.
