Specifically, the surface treatment layer 43 and the protective layer 41 are both UV-curable coatings, and the pattern layer 42 is a pattern formed by UV ink spray painting.

The decorative plate prepared in this example and a common spray-painted decorative plate were subjected to physical and chemical property tests, and the results are shown in table 1:

table 1 comparison of the test results of the examples and the common spray-painted decorative board

As can be seen from Table 1, the interconnected UV spray painting intelligent plate with the 3D effect, which is manufactured by the invention, has better adhesive force, wear resistance, scratch resistance, color fidelity durability and environmental protection property than the common spray painting decorative plate, has obvious 3D stereoscopic effect and good conductive performance, can realize interconnection and can be widely applied to various decorative places.
