Abstract
The present invention provides a flexible polyurethane foam showing sufficient physical properties and reduced volatile amine components. It is therefore possible to provide the flexible polyurethane foam, enabling to improve working environments during the production process and reduce volatile amines discharged from the products. The present invention also provides excellent seat pads and sound absorbing materials for automobiles, comprising the flexible polyurethane foam. The flexible polyurethane foam is produced by contacting the polyol composition (A) comprising a polyether polyol (an amine value: 400 to 600 mg KOH / g, a hydroxyl value: 350 to 700 mg KOH / g), which is the adduct of an alkylene oxide to a compound selected from formulas (1) and (2), with an organic polyisocyanate in the presence of water. In the formulae, R 1 and R 2 represent H or (CH) n -NH 2 (n: 1-3), R 3 - R 6 and R 7 represent H or an alkyl group or alkenyl group having 1 to 4 carbon atoms, and k and m represent 1 to 6.
Description
Technical field [0001] The present invention relates to a soft polyurethane foam and a seat cushion and sound-absorbing material composed of the soft polyurethane foam. More specifically, it relates to an excellent flexible polyurethane foam that has sufficient physical properties that can be obtained by using a specific polyether polyol and can reduce volatile amine components, and a seat cushion and sound absorbing material made of the same. Background technique [0002] The polyurethane foam is produced by reacting a polyol and a polyisocyanate in the presence of a catalyst, a blowing agent, a surfactant, a crosslinking agent, and the like added as necessary. It is known that a large amount of metal compounds or tertiary amine compounds are used as catalysts in the production of the polyurethane resin. These catalysts are used in large quantities in the industrial manufacture of polyurethane resins individually or simultaneously. Among these catalysts, especially tertiary amin...
