| titleOfInvention | A kind of high temperature resistant and high crosslinking thermosetting resin system and preparation method thereof |
| abstract | The invention discloses a high-temperature-resistant and high-crosslinking thermosetting resin system and a preparation method thereof. The preparation method comprises mixing resveratrol, allylamine and paraformaldehyde into an organic solvent, and then raising the temperature to 110-125 DEG C to continue the reaction 4 -8h, after the reaction is completed, the reaction solution is subjected to alkaline washing, rotary evaporation, and drying to obtain a trifunctional benzoxazine monomer containing acryl; Physical blending is carried out at room temperature according to the molar ratio, and after mixing uniformly, the thermosetting resin with high temperature resistance and high crosslinking is obtained after heating, curing, copolymerization and crosslinking. The introduction of dithiol reduces the curing temperature of benzoxazine, thereby improving the processability of the resin; the propenyl group in benzoxazine and the thiol react with thiol-ene to further crosslink and improve the thermosetting resin material. The cross-linking density makes the cured new cross-linked material have more excellent thermodynamic and mechanical properties, and the flame retardant performance is further improved. |
