Thermally stable rigid polyurethane foam with excellent thermal insulation and mechanical properties
Rigid polyurethane foam (RPUF) had been widely used in many fields due to its excellent performance. However, its poor thermal stability had invisibly formed a certain obstacle to its further development, so it was imperative to improve its thermal stability and other properties.

| description | Rigid polyurethane foam (RPUF) had been widely used in many fields due to its excellent performance. However, its poor thermal stability had invisibly formed a certain obstacle to its further development, so it was imperative to improve its thermal stability and other properties. In the current work, a one-step method was used to successfully prepare silk fibroin-based melamine (MA) modified RPUF. The thermal stability of the modified RPUF was studied by thermogravimetric (TG) analysis and four calculated methods, and the results showed that RPUF-MA10 with an MA of 10 wt% had the highest thermal stability and apparent activation energy (E). Thermal imaging studies show that RPUF-MA10 had better thermal insulation properties than RPUF-MA0. In quasi-static compression tests, RPUF-MA10 had the highest modulus of elasticity (0.33 MPa), compressive strength (0.15 MPa), energy absorption efficiency (52.53 %) and compressive strain (76.05 %). These results were now a good reference for the engineering applications of RPUF materials. |
