Abstract
The invention discloses a polyurethane PIR (Polyisocyanurate) foam material. The polyurethane PIR foam material is prepared by reacting a composition with a curing agent react according to a mass proportion of 1:(1.5-1.7), wherein the composition is prepared from the following components in parts by mass: 80-120 parts of melamine formaldehyde resin, 90-110 parts of polyether or polyester, 1-3 parts of foam stabilizer, 25-35 parts of foaming agent, 25-35 parts of phosphorous-containing flame retardant and 0.5-1 part of catalyst, wherein the curing agent is one or more of PAPI (Polymethylene Isocyanate) compounds. The rigid polyurethane PIR foam provided by the invention has the characteristics that melamine resin is contained, so that high nitrogen content is achieved; a part of phosphorous-containing flame retardant is contained, so that a nitrogen-phosphorus synergistic effect is achieved; the oxygen index is greater than 30, so that the B1-level requirement on national building exterior wall insulation materials can be met.
