Abstract
The present invention provides a laminate 10 including: a foamed polyurethane layer 11 obtained from a foamable polyurethane resin composition containing an active hydrogen group-containing tin ricinoleate and a phosphorus-containing solid flame retardant; and a coating layer 15 adhered to the foamed polyurethane layer 11 by a polyurethane hot melt adhesive 13 containing a polyurethane prepolymer (I) obtained by using a polyol component (A) and a polyisocyanate component (B) as raw materials, and a catalyst (II).
Claims9
A laminate comprising:
- a foamed polyurethane layer obtained from a foamable polyurethane resin composition containing a polyol, a polyisocyanate, a foaming agent, a catalyst and a flame retardant;
- and
- a coating layer mounted on the foamed polyurethane layer,
- wherein the foamable polyurethane resin composition contains an active hydrogen group-containing tin ricinoleate as the catalyst and a phosphorus-containing solid flame retardant as the flame retardant,
- the foamed polyurethane layer and the coating layer are adhered by a polyurethane hot melt adhesive containing a polyurethane prepolymer (I) obtained by using a polyol component (A) and a polyisocyanate component (B) as raw materials, and a catalyst (II),
- the polyisocyanate component (B) in the polyurethane hot melt adhesive contains more than 0.5 mass % and 10 mass % or less of a carbodiimide-modified diphenylmethane diisocyanate based on the total mass of polyisocyanate component (B), and
- the catalyst (II) includes a reactive catalyst having a functional group that reacts with an isocyanate group.
