[0018] First, weigh 10g of weeping willow leaves, put them into a pulverizer, and pass through an 80-mesh sieve to obtain weeping willow leaf powder. Put the powder into a beaker, then add 100mL of deionized water, soak for 2h, and then add 2g of potassium sulfate, 20mL of mass The concentration is 20% sodium hydroxide solution, soaked for 3 hours, filtered to obtain the filtrate, which is the initial extract; add the above initial extract to the fermenter, then inoculate 0.3g of Bacillus subtilis in the fermenter, and control the fermentation temperature to 25 ℃, humidity 65%, fermented for 24 hours, filtered to obtain the filtrate, that is, the stock solution of weeping willow leaves, and set aside; weigh 10g of bisphenol A epoxy resin and add it to a three-necked flask with a thermometer and a reflux device, and then add 50mL of anhydrous Ethanol, put the flask in a water bath, raise the temperature to 80°C, stir for 1 hour, then add 3g of polyethylene glycol and 0.3g of zin...
