Comparative example 1
A comparative example was prepared in a similar manner to example 1, except that the wear-resistant powder alumina was replaced with glass frit on the basis of example 1.
Comparative example 2
This comparative example was prepared in a similar manner to example 1 except that the wear-resistant powder alumina was replaced with fine silica powder on the basis of example 1.
Comparative example 3
This comparative example was prepared similarly to example 1, except that the nano-sized polyether acrylate resin was replaced with the hexafunctional urethane acrylate on the basis of example 1.
Comparative example 4
This comparative example was prepared in a similar manner to comparative example 3, except that the wear-resistant powder alumina was replaced with glass frit on the basis of comparative example 3.
Comparative example 5
This comparative example was prepared in a similar manner to comparative example 3 except that the wear-resistant powder alumina was replaced with fine silica powder on the basis of comparative example 3.
Performance testing and analysis
The photo-curing matte finishing paints prepared in examples 1-3 and comparative examples 1-5 were coated on a substrate with the same size in the same amount, and then immersed in boiling water for 24 hours, lubricating oil for 24 hours, instant coffee for 1 hour, and 95% medical alcohol for 1 hour, and then taken out and washed with water for testing stain resistance, and friction resistance was tested 160 times with 6N friction using a Martindale abrasion tester, and the test results are shown in Table 1.
TABLE 1
As can be seen from Table 1, the photocuring matte finishing paint prepared by the invention has excellent stain resistance and friction resistance. As shown in comparative examples 1-2, replacement of the wear-resistant powder alumina results in a decrease in the abrasion resistance and even a slight effect on the stain resistance. As shown in comparative example 3, the nano-sized polyether acrylate resin decreased the abrasion resistance if the main resin was replaced. As shown in comparative examples 4 to 5, if the nano-scale polyether acrylate resin and the wear-resistant powder alumina were replaced at the same time, the stain resistance would be significantly reduced while the abrasion resistance would be poor.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
