POLY URETHANE FOAM HAVING LIQUID AGENT FOR REMOVING ALDEHYDES AND PREPARATION METHOD THEREOF

摘要

The present invention provides a polyurethane foam containing 0.1 to 5 parts by weight of a liquid phase removing agent for reducing aldehyde based on 100 parts by weight of polyol before forming of a polyurethane foam, wherein the liquid phase removing agent for reducing aldehyde contains 5 to 40 wt% of a compound having an amine group, 5 to 30 wt% of a natural compound having an antioxidative function, 5 to 20 wt% of a surfactant; and a remaining amount of a solution having a hydroxyl group. Therefore, without a high cost photocatalyst or metal salt carrier for reducing a volatile organic compound (VOC) exhausted from a polyurethane foam, a polyurethane foam having reduced aldehyde generation can be prepared. The liquid phase removing agent for reducing aldehyde prepared in a liquid phase shows increased affinity with polyol during preparation of polyurethane foam and can greatly reduce an amount of generated acetaldehyde and formaldehyde which are volatile organic compounds exhausted from polyurethane foam.
