Embodiment 1
[0024] Add 5g ethylene-vinyl acetate copolymer, 4g rosin and 3g ferrocene boric acid to the crucible, grind evenly, heat to 160°C, stir for 1 hour, cool to 150°C to get ferrocene borate glue; the area is 100cm 2 , the weight is 160g / m 2 The cellulose acetate is arranged on the turntable of the glue homogenizer, the temperature of the turntable is controlled at 150°C, and the rotation speed is 500 rpm, and 5g of ferrocene borate glue is added dropwise on the acetate cloth, and the temperature of the turntable is lowered to 25°C. Add dropwise 5 g of 3-aminopropyltrimethoxysilane in acetone solution with a mass concentration of 3%, dry it in the air, then raise the temperature of the turntable to 100°C, keep it for 10 minutes, lower the temperature of the turntable to 25°C, and stop the turntable to obtain Acetate cloth water treatment composite.
[0025] Add 100mL of deionized water, 2g of copper sulfate, 3g of citric acid, 3g of ethylenediaminetetraacetic acid, 1g of NaOH and ...
