Embodiment 1
[0036] (1) Mix 11.8g of concentrated hydrochloric acid with 60g of deionized water, and mix 2g of EO 20 PO 70 EO 20 and 1.52g Potassium Chloride were added to the above mixed solution and stirred evenly;
[0037] (2) Add 1.5 g of mesitylene to the mixture obtained in step (1), and stir at 35° C. for 2 hours.
[0038] (3) Weigh 4.25 g tetraethyl orthosilicate, add it dropwise to the mixed solution obtained in step (2), and stir for 10 min.
[0039] (4) The mixture of step (3) was transferred to a tetrafluoroethylene hydrothermal kettle, and the hydrothermal kettle was placed in an oven, hydrothermally stood at 35°C for 24h, and then hydrothermally stood at 100°C for 36h.
[0040] (5) Filter the solid-liquid mixture obtained in step (4) with a suction filtration device to remove the solid, wash it with deionized water, and finally place it in a vacuum drying oven at 60° C. for 12 hours;
