Abstract
Official abstract text for this publication.
To provide a method for producing a low-odor polyester-type flexible polyurethane foam which is excellent in formability and free from scorch in the interior of the foam, and further discharges substantially no volatile amine compound from a product, in the production of a polyester-type flexible polyurethane foam, and to provide a catalyst composition to be used for the production method. A polyester-type flexible polyurethane foam is produced by a process which comprises reacting a polyester polyol with a polyisocyanate, in the presence of a catalyst composition containing one or more amine compounds selected from the group consisting of an amine compound represented by the following formula (1): in the above formula (1), R 1 is a C 1-6 linear or branched alkyl group, and each of R 2 , R 3 , R 4 and R 5 which are independent of one another, is a hydrogen atom or a C 1-2 alkyl group, an amine compound represented by the following formula (2): in the above formula (2), R 6 is a C 2-6 linear or branched alkylene group, and an amine compound represented by the following formula (3): in the above formula (3), each of R 7 and R 8 which are independent of each other, is a C 1-4 alkyl group, and R 9 is a C 3-5 linear or branched alkylene group; a blowing agent; and a surfactant.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a flexible polyurethane foam, which comprises reacting a polyester polyol with a polyisocyanate, in the presence of a catalyst composition containing: (1) N-Methylpiperazine (2) an amine compound selected from at least one of N-Hydroxyethylmorpholine, N,N-Dimethylisopropanolamine and/or N-Hydroxyisopropylmorpholine; a blowing agent; and a surfactant. 2. The method for producing a flexible polyurethane fo…
