摘要: Provided is a polyol composition which has good dispersion stability of a polyuria resin contained therein and maintains a uniform appearance over time as well as during the production, and which can be reacted with polyisocyanate to obtain a polyurethane foam having excellent flame retardancy. The present invention pertains to a polyol composition that is used as a raw material for a polyurethane foam containing a urea group-containing reaction product having a compound (A), which has two primary amino groups and at least one polyalkyleneoxy chain (a) in the molecule, and a polyisocyanate (B) as essential raw materials, and being obtained by reacting the primary amino groups of the (A) with the isocyanate groups of the (B), wherein the polyalkyleneoxy chain (a) is a chain to which 1-100 moles of a C2-4 alkylene oxide have been added.

摘要: The present invention discloses a viscoelastic sound-absorbing polyurethane foam and a method for preparing the same, the foam being prepared by reacting a polyisocyanate composition and an isocyanate reactive component. The isocyanate reactive component comprises, based on the weight of mixed polyethers, 30-80 wt % of (bii) a copolyol of epoxypropane-epoxyethane, or a conjugate thereof, wherein the content of oxy-ethylidene unit is 5-35 wt %; 2-20 wt % of (biii) a copolyol of epoxypropane-epoxyethane, or a conjugate thereof, wherein the content of oxy-ethylidene unit is 70-100 wt %; and 20-70 wt % of (biv) a copolyol of epoxypropane-epoxyethane, or a conjugate thereof, wherein the content of oxy-ethylidene unit is 0-20 wt %. The sound-absorbing foam of the present invention has a ball rebound rate of 15-30% and good sound absorption performance.
