Example Embodiment
[0017] Example 1
[0018] First take the waste silk, wash the surface with water, and then soak it in a 5% hydrogen peroxide solution, add 2% chitosan by mass to the waste silk, and adjust the pH to 30% hydrochloric acid solution. 5.0, then heat up, set the temperature to 60℃, keep the temperature for 40 minutes and then cool to room temperature naturally, filter and collect the filtrate; put the obtained filtrate in an oven, dry at 90℃ for 1h, and then dry the filtrate Put it in a pulverizer for pulverization, pass through an 80-mesh sieve, mix the powder with water at a solid-liquid ratio of 1:2, and adjust the pH of the mixed solution to 3.0 with a 40% mass fraction of phosphoric acid solution, stand for 1h after acidification treatment, and filter , Collect the filtrate, put the filtrate into an air dryer to air dry, then put it into a pulverizer and pulverize after air drying, pass a 200-mesh sieve to obtain acidified silk powder; take the expanded vermiculite into a calcine...
