Comparative example 2
Comparative example 2 differs from example 1 only in that the top coat in comparative example 2 does not add a hand wear-resistant agent.
Comparative example 3
Comparative example 3 differs from example 1 only in that the primer in comparative example 3 does not add an adhesion promoter.
2. Performance testing
The primer and the top coat prepared in the above examples and comparative examples were applied by spraying, the primer was applied on the substrate, then the top coat was applied on the primer, and then performance test was performed according to the coating HG/T4758-2014 standard, and the test results are shown in tables 1-2.
TABLE 1
TABLE 2
As shown in Table 1, the crack paint prepared by the invention has the water resistance of not less than 240H, the acid resistance of not less than 96H, the alkali resistance of not less than 72H, the oil resistance of not less than 24H, the gasoline resistance of not less than 24H, the hardness of H, the adhesion of 0 level, the impact strength of 50cm passing, the artificial aging resistance of 1000H, no pulverization, bubbling, falling and cracking, and the abrasion resistance of not less than 0.5mm.
As is clear from comparison between the example 1 and the comparative examples 1-2, the comparative example 2 is not added with the hand feeling wear-resistant agent, so that the prepared crack paint is poor in hardness, adhesive force and wear resistance, while the comparative example 1 is added with the hand feeling wear-resistant agent, but not with scratch-resistant auxiliary agent, the hardness, adhesive force and wear resistance of the crack paint are improved to a limited extent, but the example 1 is added with the hand feeling wear-resistant agent and the scratch-resistant auxiliary agent at the same time, the hardness, adhesive force and wear resistance of the crack paint are improved to a great extent, and the effect brought by the single addition of the hand feeling wear-resistant agent or the scratch-resistant auxiliary agent is far better than that brought by the single addition of the hand feeling wear-resistant agent, the scratch-resistant auxiliary agent and other components in the finish paint are enhanced in a synergistic manner, so that the hardness, adhesive force and wear resistance of the crack paint are improved to a great extent.
As can be seen from the comparison of the example 1 and the comparative example 3, the adhesion promoter is not added in the comparative example 3, and experiments show that the added adhesion promoter not only can enhance the adhesion of the finish paint, but also can enhance the wear resistance and the hardness of the crack paint, thus indicating that the adhesion promoter and other components in the invention generate a synergistic enhancement effect.
