    Abstract: The present invention relates to imidazole and/or its derivative as polyurethane or polyisocyanurate foam catalyst in the presence of Low Global Warming Potential (GWP) halogenated olefinic blowing agents, such as the hydrochlorofluoroolefin (HCFO) HCF0-1233zd. More particularly, the present invention relates to catalyst compositions comprising imidazole and/or its derivative. The present invention further relates to the stable pre-blend formulations and resulting polyurethane or polyisocyanurate foams. A method for stabilizing thermosetting foam blends comprises combining: (a) a polyisocyanate and, optionally, isocyanate compatible raw materials; and (b) a polyol pre-mix composition comprising a halogenated olefinic blowing agent, a polyol, a surfactant and a catalyst.

    Abstract translation: 本发明涉及在低全球变暖潜能值(GWP)卤代烯烃发泡剂如氢氯氟烯烃(HCFO)HCF0-1233zd的存在下,作为聚氨酯或聚异氰尿酸酯泡沫催化剂的咪唑和/或其衍生物。 更具体地说,本发明涉及包含咪唑和/或其衍生物的催化剂组合物。 本发明还涉及稳定的预共混配方和所得聚氨酯或聚异氰脲酸酯泡沫。 一种用于稳定热固性泡沫共混物的方法包括:(a)多异氰酸酯和任选地与异氰酸酯相容的原料; 和(b)包含卤代烯烃发泡剂,多元醇,表面活性剂和催化剂的多元醇预混组合物。
