Embodiment 1
[0042] A preparation method of a high-strength separation membrane with a reinforcing material, the preparation method comprising the steps of:
[0043] ①Add 20g of polyvinylidene fluoride and 8g of PEG-600 to 72g of DMAc, mechanically stir at 80°C for 12h, filter, stand still for 6h, and defoam to obtain the film-making solution;
[0044] ② Blend 15g of toluene diisocyanate with 1g of calcium oxide, stir at room temperature for 12 hours, filter and stand for 6 hours, and defoam to obtain a reinforcing material;
[0045] ③ will be as figure 2 The three-channel nozzle shown is heated to 80°C, and the deionized water flows out from the deionized water outlet of the three-channel nozzle through independent channels. The film-making solution is extruded at the same time, falls vertically into the gel in deionized water, is drawn after being wound by a winding wheel, and soaked in deionized water to obtain a high-strength separation membrane with reinforcing materials.
Embodiment 2
[0047] A preparation method of a high-strength separation membrane with a reinforcing material, the preparation method comprising the steps of:
[0048] ①Add 18g of polyethersulfone and 8g of PEG-200 to 74g of DMAc, mechanically stir at 80°C for 12h, filter, stand still for 6h, and defoam to obtain a membrane-forming solution;
[0049] ② Blend 19g of toluene diisocyanate with 1g of calcium oxide, stir at room temperature for 12h, filter, stand for 6h, and defoam to obtain a reinforcing material solution;
[0050] ③ will be as figure 2 The three-channel nozzle shown is heated to 80°C, and the deionized water flows out from the deionized water outlet of the three-channel nozzle through independent channels. The film-making solution is extruded at the same time, falls vertically into the gel in deionized water, is drawn after being wound by a winding wheel, and soaked in deionized water to obtain a high-strength separation membrane with reinforcing materials.
Embodiment 3
[0052] A preparation method of a high-strength separation membrane with a reinforcing material, the preparation method comprising the steps of:
[0053]① Add 20g of polysulfone and 8g of PEG-200 into 72g of DMF, mechanically stir at 80°C for 12h, filter, stand still for 6h, and defoam to obtain the membrane-forming solution;
[0054] ② Blend 19g of toluene diisocyanate with 1g of calcium oxide, stir at room temperature for 12h, filter, stand for 6h, and defoam to obtain a reinforcing material solution;
[0055] ③ will be as figure 2 The three-channel nozzle shown is heated to 80°C, and the deionized water flows out from the deionized water outlet of the three-channel nozzle through independent channels. The film-making solution is extruded at the same time, falls vertically into the gel in deionized water, is drawn after being wound by a winding wheel, and soaked in deionized water to obtain a high-strength separation membrane with reinforcing materials.
