[0037] Bamboo fibril-reinforced composites of eugenol methacrylate cross-linked palm oil-based resin:
[0038] The synthesis process of eugenol methacrylate: a certain amount of liquid eugenol was placed in a round-bottomed flask, and then methacrylic anhydride and 4-dimethylaminopyridine were added, wherein the molar ratio of methacrylic anhydride to eugenol was The amount of 3:1, 4-dimethylaminopyridine was 5% (molar ratio) of methacrylic anhydride; the flask was placed in an ultrasonic water bath, and the magnetic stirring was 500 r / min at 60 °C for 12 h. The ultrasonic power was 80W; the reaction products were respectively subjected to saturated NaHCO 3 The solution, 0.5mol / L NaOH solution and distilled water were repeatedly purified several times, and then they were mixed in MgSO4 Under drying conditions for 24h, eugenol methacrylate was obtained.
