| titleOfInvention | Method for improving toughness and flame retardant property of polyisocyanurate |
| abstract | The invention belongs to the field of modification of high molecular resin, and particularly relates to application of polydimethylsiloxane in toughening polyisocyanurate and improving flame retardant property. The expressions for the three block copolymers are: PVP-b-PDMS-b-PVP, PS-b-PDMS-b-PS and PMMA-b-PDMS-b-PMMA, wherein PDMS is polydimethylsilane, PVP is polyvinylpyrrolidone, PS is polystyrene, and PMMA is polymethyl methacrylate. The molecular weight of the triblock copolymer is 8000-50000g/mol, wherein the molecular weight of PDMS is 1000-6000 g/mol. According to the invention, the three block copolymers are respectively mixed into the polyisocyanurate to respectively obtain uniformly dispersed PDMS nano microphase structures, so that the polyisocyanurate toughening effect is obvious and the flame retardant property of the polyisocyanurate is improved to a certain extent. |
