Embodiment 1
[0021] (1) Add 2g of pentaerythritol to 1000mL of ethyl acetate, stir mechanically at room temperature for 30min, then add 10g of polyetheretherketone with an average particle size of 2μm, stir mechanically at room temperature for 30min, then sonicate for 2h, and finally add 1g Toluene diisocyanate was mechanically stirred at room temperature for 30 minutes to obtain a mixed dispersion of pentaerythritol, polyether ether ketone and toluene diisocyanate;
[0022] (2) Place the dried bamboo sample in an automatic vacuum pressurized tank, evacuate to a vacuum degree of 0.01MPa, and keep the pressure for 30min, inject the above mixed dispersion, pressurize to 2MPa, and keep the pressure for 3h, Relieve the pressure, continue soaking under normal pressure for 1 hour, take out the bamboo sample and remove the residual liquid on the surface, and vacuum dry it at room temperature for 24 hours to obtain a pretreated bamboo sample;
[0023] (3) Evenly spray the pretreated bamboo sample ...
Embodiment 2
[0027] (1) Add 8g of 1,4-butanediol into 1500mL of ethyl acetate, stir mechanically at room temperature for 45min, then add 30g of polyether ether ketone with an average particle size of 5μm, stir mechanically at room temperature for 40min, then Sonicate for 3 hours, finally add 5 g of isophorone diisocyanate, and mechanically stir for 45 minutes at room temperature to prepare a mixed dispersion of 1,4-butanediol, polyetheretherketone and isophorone diisocyanate;
[0028] (2) Place the dried bamboo sample in an automatic vacuum pressure tank, evacuate to a vacuum degree of 0.02 MPa, and keep the pressure for 60 minutes, inject the above mixed dispersion, pressurize to 3 MPa, and keep the pressure for 2 hours, Relieve the pressure, continue to impregnate for 2 hours under normal pressure, take out the bamboo sample and remove the residual liquid on the surface, and vacuum dry it at room temperature for 24 hours to obtain a pretreated bamboo sample;
[0029] (3) Evenly spray the...
