s1, taking the following components by weight: 35 parts of methyl methacrylate, 25 parts of phenyl ortho-hydroxybenzoate, 35 parts of acrylamide, 72 parts of epoxy resin emulsion, 20 parts of glycidyl methacrylate, 15 parts of N, N-methylene bisacrylamide, 15 parts of ethylene glycol dimethacrylate and 5 parts of methyl silicone oil;
s2, preparing a primer: adding methyl methacrylate, phenyl ortho-hydroxybenzoate, acrylamide and epoxy resin emulsion into a reaction kettle at the temperature of 98 ℃, and preserving the temperature for 30 min;
s3, preparing a surface coating: pouring the primer into a stirrer, adding glycidyl methacrylate, N-methylene bisacrylamide, ethylene glycol dimethacrylate and methyl silicone oil, stirring and dispersing, controlling the stirring speed to be 2000r/min, and stirring for 5 min;
s4, primary coating: spraying a primer on the surface of the seat 11, controlling the spraying amount to be 45g/m2, and curing by using UV light after spraying, wherein the UV curing energy is 500mj/cm2, the peak value is 70mw/cm2, and the curing time is controlled to be 50s to form the primer layer;
s5, secondary coating: the surface of the seat 11 was subjected to electrostatic dust removal treatment, and the topcoat was sprayed on the primer layer at a coating weight of 20g/m2 and dried at 73 ℃ to form a continuous uniform coating layer.
The seats 11 coated with the antifouling coatings of examples 2 to 5 were subjected to tests of surface hardness and peel strength, and for the sake of comparison, the data of all examples were normalized based on the data of example 2.
TABLE 1
| Surface hardness | Peel strength | |
| Example 2 | 100% | 100% |
| Example 3 | 131% | 122% |
| Example 4 | 116% | 103% |
| Example 5 | 112% | 111% |
As can be seen from the above, since the test results of the surface hardness and the peel strength of the antifouling coating on the surface of the seat 11 in example 3 are higher than those of the other examples coated with the antifouling coating, the preparation method of the antifouling coating given in example 3 is the most preferable choice.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
