Example Embodiment
[0035] The preparation of the above composite material is to first coat the lower outer surface layer 3 with an adhesive coating or film on the upper surface, the intermediate layer 2 and the upper outer surface layer 1 with an adhesive coating or film on the lower surface in sequence. After stacking, use a vacuum thermal laminator for hot pressing and cooling.
[0036] Since the upper outer surface layer 1 and the lower outer surface layer 3 are both formed of transparent polymer, at least one surface of the textile fabric 21 contained in the intermediate layer 2 has an artistic pattern, and the hot-pressing adhesive is a light-transmitting polymer. , The obtained composite material has multiple functions such as high light transmittance, artistic decoration, lightness, and high strength, and the processing is simple and convenient, and various complicated artistic patterns can be realized without complicated coating processes. It is not only decorative The effect is obvious, an...
