| titleOfInvention | Benzoxazine resin containing alkynyl and aryl ether nitrile structure, composite material and preparation method thereof |
| abstract | Benzoxazine resin containing alkynyl and aryl ether nitrile structure, composite material and preparation method thereof, belonging to the technical field of high polymer material. The molecular structural formula of the benzoxazine resin containing alkynyl and aryl ether nitrile structure is as follows: the preparation method comprises the following steps: firstly, binary phenolic compounds, dihalogenated benzonitrile compounds and basic compound catalysts are adopted to synthesize poly (arylene ether nitrile) oligomers with phenolic hydroxyl end capping in polar aprotic solvents; then reacting with aldehyde compounds and aminophenylacetylene to synthesize benzoxazine resin containing alkynyl and aryl ether nitrile structures; it is compounded with fiber to prepare composite material. The molecular structure of the benzoxazine resin is simultaneously introduced with alkynyl, aryl ether and arylnitrile groups, so that the solubility, the reactivity and the compatibility with other thermosetting resins of the resin are improved, and the comprehensive mechanical property and the adhesive force of the resin are improved; is a high-performance resin system with excellent processing performance, heat resistance and mechanical property. |
