Embodiment 1
[0021] Weigh 50g of lignin, dissolve it with 50g of deionized water, centrifuge at 12,000 rpm for 8 minutes to remove impurities, adjust the pH of the centrifuged solution to 2-3 with concentrated hydrochloric acid to precipitate lignin, and then dissolve the precipitated Dissolve the lignin with deionized water of the same weight, centrifuge as above, remove impurities, adjust the pH value, make the lignin precipitate again, and dry the last precipitated lignin for later use; prepare a concentration of 30g / L lignin solution (lignin adjustment) respectively The pH of the lignin solution is 7) and the concentration is 50mmol / L copper sulfate solution; slowly drop 50mL copper sulfate solution into 50mL lignin solution, continue magnetic stirring, and react at 90°C for 2h to obtain nano-cuprous oxide suspension ; Filter the suspension to obtain a nano-cuprous oxide filter cake, wash the filter cake three times with distilled water, and dry at 20° C. for 24 hours to obtain a lignin...
Embodiment 2
[0024] The steps refer to Example 1, the difference is that the pH of the prepared lignin solution is 10, and the nano-cuprous oxide filter cake obtained by filtering is dried at 70° C. for 6 hours; 25 g of the prepared cuprous oxide powder and 8 g of polyepoxysuccinic acid, Add 12g of polymaleic anhydride, 0.5g of OP-100, and 0.5g of BS-12 into 54g of water and perform ball milling for 2 hours to obtain a nano-cuprous oxide fungicide composition.
Embodiment 3
[0026] Referring to Example 1, the difference is that the prepared lignin solution has a pH of 11, and the obtained nano-cuprous oxide filter cake is dried at 40° C. for 15 hours; 15 g of the prepared cuprous oxide powder, 2 g of polyaspartic acid, Add 8 g of polyacrylic acid, 1 g of penetrant JFC, and 0.5 g of sodium dodecylbenzenesulfonate into 73.5 g of water and perform ball milling for 3 hours to obtain a nano-cuprous oxide fungicide composition.
