Amine catalyst composition for production of haloalkene foamed polyurethane

Abstract

Provided is a catalyst composition which improves the storage stability of a liquid polyol blend for the production of a polyurethane foam, said blend containing a hydrohaloolefin as a foaming agent,and which starts a quick foaming reaction with a small addition amount. Also provided is a method for producing a polyurethane foam with use of a liquid polyol blend which contains this catalyst composition. The present invention uses a catalyst composition which contains: one or more alcohols selected from the group consisting of alcohols represented by general formula (1) (hereinafter referred to as the alcohols represented by general formula (1)) and alcohols represented by general formula (2) (hereinafter referred to as the alcohols represented by general formula (2)); and one or more tertiary amine compounds selected from the group consisting of hexamethyl triethylene tetramine, N, N, N'-trimethyl aminoethyl ethanolamine, N, N-dimethylamino ethoxy ethanol, N, N-dimethyl-N', N'-di(2- hydroxypropyl)propylene diamine, N, N, N'-trimethyl-N'-(2- hydroxyethyl)bis(2-aminoethyl) ether and N, N-dimethylamino ethyl-N'-methylamino ethyl-N"-methylamino isopropanol. (In general formula (1), R1represents an unsaturated hydrocarbon group containing at least one double bond and having 5-20 carbon atoms, a linear alkyl group having 6, 8, 10 or 12 carbon atoms or a branched alkyl group having12-24 carbon atoms.) (In general formula (2), m represents a number of 1-4.)

Description

technical field [0001] This invention relates to amine catalyst compositions for use in the manufacture of polyurethane foams. More specifically, the present invention relates to a polyol mixed solution containing a combination of a polyol, a hydrohaloolefin, and a specific amine catalyst composition and having excellent storage stability, and an organic compound using the polyol mixed solution and an organic compound. Process for the manufacture of polyisocyanate polyurethane foam. Background technique [0002] A polyurethane foam is usually produced by reacting a polyol and a polyisocyanate in the presence of a catalyst and, if necessary, a blowing agent, a surfactant, a crosslinking agent, and the like. [0003] In recent years, hydrohaloolefins including hydrofluoroolefins (HFOs) and hydrochlorofluoroolefins (HCFOs) with low global warming coefficients have been newly proposed as preferred blowing agents. Examples of such hydrofluoroolefins include: trans-1,3,3,3-tetra...

AI Technical Summary

Problems solved by technology

When sterically hindered amines are used, the storage life of the second component is long, but the catalytic activity of the foaming reaction is poor, so the foaming reaction cannot be initiated quickly in the manufacture of polyurethane foam, resulting in serious problems such as liquid dripping in the spraying method question
