| titleOfInvention | A kind of Halogen composite flame-proof Polyimide foams and preparation method thereof |
| abstract | The present invention discloses a kind of Halogen composite flame-proof Polyimide foams and preparation method thereof.The foamed material is made of the raw material of following parts by weight: 100 parts of aromatic dianhydride, 50~500 parts of polar solvent, 5~30 parts of fatty alcohol, 5~20 parts of deionized water, 15 parts of foam stabiliser, 5 parts of composite catalyst, 4~100 parts of Halogenless composite fire retardant, 100~500 parts of polyisocyanates.It is reacted the preparation method is that aromatic dianhydride heats in polar solvent with fatty alcohol；Add deionized water, foam stabiliser and composite catalyst, Halogenless composite fire retardant obtains suspension；It is eventually adding that polyisocyanates is foamed and heating in vacuum solidification, finally obtains fire-retardant Polyimide foams.Foamed material obtained by the present invention has the characteristics that density is low, cell size distribution is uniform, mechanical property, heat resistance and flame retarding and smoke suppressing properties are excellent.It can satisfy the requirement of the high-end fields such as aerospace, navigation Polyimide foams. |
