Embodiment 1
[0030] Add 0.5 g of chitosan (CS) to 99.5 ml of deionized water, stir at room temperature and adjust the pH of the solution to 4 with glacial acetic acid to obtain a uniform solution; take 1 g of boric acid (BA) 99 ml of deionized water was stirred to obtain a uniform solution; at 70 ° C, the reed braided product was immersed in the chitosan solution for 24 hours, and then the soaked reed braided product was immersed in the boric acid solution for 24 hours. This is repeated for 5 cycles; after the reaction is completed, the obtained reed weaving is washed and dried to obtain a bio-based flame-retardant reed weaving.
Embodiment 2
[0032] Add 0.5 g of chitosan (CS) to 99.5 ml of deionized water, stir at room temperature and adjust the pH of the solution to 4 with glacial acetic acid to obtain a uniform solution; take 3 g of boric acid (BA) 97 ml of deionized water was stirred to obtain a uniform solution; at 70 ° C, the reed braided product was immersed in the chitosan solution for 24 hours, and then the soaked reed braided product was immersed in the boric acid solution for 24 hours. This is repeated for 5 cycles; after the reaction is completed, the obtained reed weaving is washed and dried to obtain a bio-based flame-retardant reed weaving.
Embodiment 3
[0034] Add 0.5 g of chitosan (CS) to 99.5 ml of deionized water, stir at room temperature and adjust the pH of the solution to 4 with glacial acetic acid to obtain a uniform solution; take 5 g of boric acid (BA) 95 ml of deionized water was stirred to obtain a uniform solution; at 70 ° C, the reed braided product was immersed in the chitosan solution for 24 hours, and then the soaked reed braided product was immersed in the boric acid solution for 24 hours. This is repeated for 5 cycles; after the reaction is completed, the obtained reed weaving is washed and dried to obtain a bio-based flame-retardant reed weaving.
