Embodiment 1
[0026] A method for preparing dihydrocarbyl dithiophosphoric acid modified zinc oxide nanoparticles, specifically: adding 0.5 mL of 1.6 mol / L methanol solution of sodium hydroxide to 15 mL of 0.053 mol / L zinc dihydrocarbyl dithiophosphate while stirring (R 1 And R 2 Respectively n-butyl and n-octyl, the specific structure is shown in Table 1) in tetrahydrofuran, reacted at 40 ℃ for 10 h, through rotary evaporation, washing, and drying to obtain light yellow powder, which is the dihydrocarbyl dithiophosphoric acid modified zinc oxide nano grain.
[0027] The TEM picture of the prepared dihydrocarbyl dithiophosphoric acid modified zinc oxide nanoparticles can be seen figure 1 . by figure 1 It can be seen that the prepared dihydrocarbyl dithiophosphoric acid modified zinc oxide nanoparticles have a uniform particle size and an average particle size of 4 nm. The organic modifier dihydrocarbyl dithiophosphoric acid isolates the zinc oxide nanoparticles and inhibits the size of the nan...
Embodiment 2
[0033] A method for preparing dihydrocarbyl dithiophosphoric acid modified zinc oxide nanoparticles, specifically: adding 0.5 mL of 1.6 mol / L potassium hydroxide in anhydrous ethanol solution to 15 mL of 0.053 mol / L dihydrocarbyl dithio Zinc phosphate (R 1 And R 2 The same is n-octyl group, the specific structure is shown in Table 1) in tetrahydrofuran, reacted at 30 ℃ for 12 h, and obtained light yellow powder through rotary evaporation, washing, and drying, which are dihydrocarbyl dithiophosphoric acid modified zinc oxide nanoparticles.
Embodiment 3
[0035] A preparation method of dihydrocarbyl dithiophosphoric acid modified zinc oxide nanoparticles, specifically: 0.52 mL of methanol solution of tetraethylammonium hydroxide (40 wt%) is stirred into 15 mL of 0.053mol / L dihydrocarbyl disulfide Zinc Substituted Phosphate (R 1 And R 2 The same is n-octylbenzene, the specific structure is shown in Table 1) in tetrahydrofuran, reacted at 30 ℃ for 14 h, and then obtained by rotary evaporation, washing, and drying to obtain light yellow powder, which is dihydrocarbyl dithiophosphoric acid modified zinc oxide nanoparticles.
