Proportioning optimization
The proportion of the dimethyl silicone oil A and the dimethyl silicone oil B directly influences the surface smoothness of the protective film after the coating liquid is coated, taking 0.06 part of alcohol dye solution and 0.24 part of essence as an example, the total amount of the dimethyl silicone oil A and the dimethyl silicone oil B is 99.7 parts, wherein the weight ratio of the dimethyl silicone oil A: dimethylsilicone oil B was prepared in a mass ratio of 8:1, 7:1, 6:1, 5:1, 4:1 and 3:1, respectively, to prepare coating solutions for improving the water drop angle and surface smoothness of the protective film, which were measured for surface smoothness and coefficient of friction of the protective film after application, respectively, and the results are shown in fig. 1-3 and table 1.
Wherein the friction coefficient of the coating liquid obtained by each proportion is shown in the following table,
TABLE 1 influence of the Dimethicone A/B mass ratio on the Friction coefficient
| Mass ratio of dimethyl silicone oil A to B | 3:1 | 4:1 | 5:1 | 6:1 | 7:1 | 8:1 |
| Coefficient of friction | 0.4-0.35 | 0.37-0.34 | 0.35-0.32 | 0.3-0.26 | 0.38-0.35 | 0.42-0.45 |

The coefficient of friction is a measure of the smoothness of a surface, and a lower coefficient of friction indicates a smoother surface.
