| titleOfInvention | High-strength and high-temperature-resistant MDI-based slow-rebound polyurethane sponge material and preparation method thereof |
| abstract | The invention relates to a high-strength and high-temperature-resistant MDI-based slow-rebound polyurethane sponge material and a preparation method thereof. The preparation method is as follows: firstly, expandable graphite is oxidized to obtain expanded graphene oxide EGO, and the EGO is functionalized to obtain expanded carbamic acid. Ethyl ester-silica-functionalized graphene oxide U-S@EGO as a high-temperature enhancer. Then, the corn starch was modified by phosphoesterification to obtain phosphoesterified corn starch CSP. The surface of wheat bran fiber was modified with CSP, and flame retardant phosphorus elements were added and a flame retardant carbon source was added to obtain phosphoesterified corn starch. Modified wheat bran fiber CSP@WBF. A high-strength and high-temperature-resistant MDI-based slow-rebound polyurethane sponge material is synthesized from high-temperature reinforcing agent and flame-retardant filler according to a specific formula. On the basis of not changing the structure and mechanical properties of the original slow-rebound polyurethane sponge, the stability of its physical properties at high temperature is greatly enhanced, and the flame retardancy can reach self-extinguishing from fire. |
