s7, trimming the sound-proof felt into a size matched with the semi-finished tile, then uniformly bonding the sound-proof felt to the lower surface of the complete tile by using an adhesive, wherein the number of layers for bonding the sound-proof felt is 5, and after bonding, trimming off the redundant parts to form the sound-proof layer 22;

and S8, placing the complete tile into an indoor ventilation place, and continuously drying for 3 days to completely cure and dry the resin ASA and the adhesive on the lower surface of the complete tile, so as to finally obtain the double-layer resin tile with the required sound insulation function.

The two-layer resins prepared in examples 1 to 4 were subjected to the relevant tests for sound insulation effect, compressive strength, corrosion resistance effect, and oxidation resistance effect, and for convenience of comparison, the data of all examples were normalized based on the data of example 1.

TABLE 1

As can be seen from the above table, the test results of the sound insulation effect, compressive strength, corrosion resistance and oxidation resistance of the double-layer resin tile prepared in example 2 are higher than those of the examples, so the manufacturing process of the medical-resistant nano material provided in example 2 is the optimal choice.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
