Embodiment 1
[0038] The wear-resistant additive for superhydrophobic coatings of the present embodiment is made up of the following components in mass percentage: 10% of nano-diamond, 1% of sodium hexametaphosphate, 0.01% of sodium hydroxide, and the balance is deionized water; the wear-resistant The pH of the additive is 8-10.
[0039] The preparation method of the anti-wear additive for superhydrophobic coating of the present embodiment, comprises the following steps:
[0040] 1) Add sodium hexametaphosphate and sodium hydroxide to deionized water, and use an explosion-proof high-shear emulsifier to emulsify and disperse for 20 minutes at a speed of 5000 rpm to obtain a mixed solution;
[0041] 2) While maintaining high-shear emulsification and dispersion, under 900W ultrasonic conditions, slowly add nano-diamond powder with an average particle size of 80nm into the mixture obtained in step 1) to prevent the nano-diamond powder from settling at the bottom of the container; After all the...
