Title:
Fire-resistant urethane resin constituent
Document Type and Number:
Japanese Patent JP6200435
Kind Code:
B2
Abstract:
An object of the present invention is to provide a flame retarding urethane resin composition capable of forming foam that is easily handled, has excellent flame retardancy, and maintains a constant shape when being heated. The present invention provides a flame retarding urethane resin composition containing a polyisocyanate compound, a polyol compound, a trimerization catalyst, a foaming agent, a foam stabilizer, and an additive, in which the trimerization catalyst is at least one kind selected from the group consisting of a nitrogen-containing aromatic compound, a carboxylic acid alkali metal salt, a tertiary ammonium salt, and a quaternary ammonium salt, and the additive is obtained by combining red phosphorus as an essential component with at least one kind selected from the group consisting of a phosphoric acid ester, a phosphate-containing flame retardant, a bromine-containing flame retardant, a boron-containing flame retardant, an antimony-containing flame retardant, and a metal hydroxide other than the red phosphorus.
