[0034] Example 1
[0035] First use 200 watts of oxygen plasma to treat the cotton fabric for 1 min. Measure 100 mL of absolute ethanol in a 250 mL beaker with magnetic stirring, and add 4.00 g of ammonium polyphosphate, 2.00 g of hydroxyl-terminated polydimethylsiloxane with a molecular weight of 560, 4.00 g of ethyl orthosilicate, and The cotton fabric treated by oxygen plasma (the cotton fabric is completely immersed in the solution) is magnetically stirred at 30° C. for 30 minutes to deposit ammonium polyphosphate on the surface of the cotton fabric through hydrogen bond interaction. Then, 1M ammonia water was added dropwise to the beaker, the pH value of the mixed solution was adjusted to 9, and the stirring was continued for 1 hour, so that the surface of the cotton fabric was covered with a composite coating with a micro-nano structure. Then the cotton fabric is taken out from the beaker, the cotton fabric is rinsed twice with ethanol and dried at 60°C to obtain the super...

[0042] Example 2
[0043] First use a corona discharge meter to corona treat the polyester fabric under a voltage of 10kV for 45s. Measure 100 mL of acetone into a 250 mL beaker with magnetic stirring, and add 8.00 g of ammonium polyphosphate, 1.00 g of hydroxy-terminated polydimethylsiloxane with a molecular weight of 400, 2.00 g of ethyl orthosilicate, and corona. The treated polyester fabric was magnetically stirred at 25°C for 20 minutes to deposit ammonium polyphosphate on the surface of the polyester fabric through hydrogen bond interaction. Then, 1M ammonia water was added dropwise to the beaker, the pH value of the mixed solution was adjusted to 8, and the stirring was continued for 2 hours, so that the surface of the polyester fabric was covered with a composite coating with a micro-nano structure. Then the polyester fabric is taken out of the beaker, the polyester fabric is rinsed twice with ethanol and dried at 50° C. to obtain the super-hydrophobic flame-retardant po...

[0046] Example 3
[0047] First use 200 watts of oxygen plasma to treat the ramie fabric for 2 minutes. Measure 100 mL of absolute ethanol in a 250 mL three-necked flask equipped with a magnetic stirring and reflux device, and add 2.00 g of ammonium polyphosphate, 2.40 g of hydroxy-terminated polydimethylsiloxane with a molecular weight of 800, and ethyl orthosilicate to it. The ramie fabric treated with ester 1.20g and oxygen plasma was magnetically stirred at 50°C for 60 minutes to deposit ammonium polyphosphate on the surface of the ramie fabric through hydrogen bond interaction. Then, 1M ammonia water was added dropwise to the above flask, the pH value of the mixed solution was adjusted to 8.5, and the stirring was continued for 0.5h, so that the surface of the ramie fabric was covered with a composite coating with a micro-nano structure. Then the ramie fabric is taken out from the flask, the ramie fabric is rinsed twice with ethanol and dried at 90° C. to obtain the super-h...
