| titleOfInvention | Preparation method of terephthalonitrile derivative flame-retardant epoxy resin composite material |
| abstract | The invention discloses a preparation method of a terephthalonitrile derivative flame-retardant epoxy resin. Taking terephthalonitrile derivatives as a flame retardant, epoxy resin as a matrix and a curing agent as curing, and preparing the flame-retardant epoxy resin composite material by physical stirring. And testing and characterizing the flame retardant and the flame-retardant epoxy resin composite material by adopting a limit oxygen index, a vertical combustion testing method and a Fourier infrared spectrum analysis method. The invention has the advantages that: the molecular weight of the raw material terephthalonitrile is small, the phosphorus content of the terephthalonitrile derivative flame retardant is not reduced, and the phosphorus content of the terephthalonitrile derivative flame retardant is about 10 wt%. Compared with pure epoxy resin, the epoxy resin composite material prepared by the preparation method has the limit oxygen index of 28.1% only by adding 1 wt%, and the epoxy resin composite material prepared by the preparation method can reach the UL 94V-0 level vertical burning grade only by adding 5 wt%. |
