IMPROVED STABILITY OF POLYURETHANE POLYOL BLENDS CONTAINING HALOGENATED OLEFIN BLOWING AGENT |
摘要 |
<p>A stable polyol pre-mix composition comprises a blowing agent, a polyol, a surfactant, and a catalyst composition comprising an oxygen -containing amine catalyst. The oxygen-containing amine catalyst may be, an alkanol amine, an ether amine, or a morpholine group. containing compound such as, 2.(2.dimethylaminoethoxy)ethanol or N.N.N'.trimethylaminoethylethanolamine. A stabilized thermosetting foam blend comprises: (a) a polyisocyanate and, optionally, isocyanate compatible raw materials; and (b) a polyol pre. mix composition. 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. A polyurethane or polyisocyanurate foam having uniform cell structure with little or no foam collapse comprises a mixture of: (a) a polyisocyanate and, optionally, one or more isocyanate compatible raw materials; and (b) a polyol pre-mix composition. The resultant polyurethane or polyisocyanurate foams have uniform cell structure with little or no foam collapse.</p> |
