20h obtains hydrophobic epoxy coating, and tests its water contact angle, as a result as shown in the table.
| Water contact angle (°) | |
| Embodiment 2 | 147 |
| Embodiment 3 | 155 |

| Comparative example 1 | 92 |
| Comparative example 2 | 113 |
| Comparative example 3 | 119 |
| Comparative example 4 | 98 |
According to upper table data it is found that embodiment and comparative example 1 are compared, due to the silica in comparative example 1
Grain is without the graft modification by polyacrylate, so that the water contact angle of comparative example 1 is significantly less than the contact of the water in embodiment
Angle illustrates that the building of the silica dioxide granule rough surface without graft modification is excessively poor, causes hydrophobic performance poor；Comparative example
2 and comparative example 3 in water contact angle also below embodiment, this is because only use perfluor alkyl ethyl acrylate monomer when grafting,
The silica dioxide granule of polyacrylic acid grafted modification can not utilize sulfonic acid group and epoxy resin graft, preferable can not must construct thick
Rough surface, and only use -2 methyl propane sulfonic acid monomer of 2- acrylamide when, although constructing rough surface, be an exposure to coating table
The silica dioxide granule hydrophobicity in face is poor, causes whole water contact angle smaller；Due to being not added with when preparing coating in comparative example 4
Polyoxyethylene ether fluorinated surfactant and diethylenetriamine lead to non-grafted hydrophobic segment on epoxy resin, so that coating is whole
Water contact angle decline.
