(2) Abrasion resistance test
The high wear-resistant and highly hydrophobic coatings prepared in example 1 and comparative examples 1-2 were rubbed 2000 times with a load of 0# steel wool of 1kg, and the surface condition of the coating was observed;
if the surface of the coating has no scratch, the coating is A-grade;
if the surface of the coating is scratched, the grade is B, and the measured data are shown in table 1;
(3) Hydrophobicity test
The contact angle of the high-wear-resistance and high-hydrophobicity coating prepared in the example 1 and the comparative examples 1-2 is tested by using a contact angle measuring instrument, the larger the contact angle is, the stronger the hydrophobicity of the coating is, and the measured data are shown in table 1;
(4) Gloss measurement
The glossiness of the high-wear-resistance high-hydrophobic coating prepared in the example 1 and the comparative examples 1 and 2 is tested according to GB/T1743-79 paint film glossiness test method, and the measured data is shown in Table 1;
(5) Oil resistance marking pen performance
Drawing a straight line with the length of 1cm on the high-wear-resistance and high-hydrophobicity coating prepared in the example 1 and the comparative examples 1-2 by using an oily marker, standing for 5min, and wiping the coating by using a paper towel;
if the straight line can be completely wiped off, the oil resistance marking pen performance of the coating is qualified;
if the straight line can not be completely wiped off, the oil resistance marking pen performance of the coating is unqualified
