Title:
FLAME RETARDANT COMPOSITION FOR POLYURETHANE FOAM, AND FLAME-RETARDANT POLYURETHANE FOAM HAVING THE SAME MIXED THEREIN
Document Type and Number:
Japanese Patent JP2021130801
Kind Code:
A
Abstract:
To provide: a non-red phosphorus-type flame retardant composition for polyurethane foam, which causes no drip ignition during combustion of the polyurethane foam and forms a char layer easily; and a flame-retardant polyurethane foam having the flame retardant composition for polyurethane foam mixed therein.SOLUTION: Provided is a flame retardant composition for polyurethane foam having an excellent carbonization property, comprising a phosphorus compound represented by formula (1). (In the formula, M is Mg, Al, Ca, Ti, or Zn; and m is 2, 3, or 4.)SELECTED DRAWING: None
