Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A multi-layer flat card of the present invention is described in detail below with reference to fig. 1-3: a multi-layer flat card comprising a structural body, the structural body comprising: the base layer 1 and the moisture-proof layer 2 arranged on the outer side of the base layer 1;
the base layer 1 is formed by stacking a plurality of layers of corrugated paper 3, the corrugated paper 3 is composed of an upper paper board 15, a lower paper board 4 and a wavy corrugated paper core 5, the corrugated paper core 5 is arranged between the upper paper board 15 and the lower paper board 4, a reinforcing net 6 is arranged between the corrugated paper 3, and the reinforcing net 6 is composed of plastic strips 7 which are mutually vertically and alternately arranged;
the corrugated structure is adopted, so that the base layer 1 has the advantages of light weight, high strength and convenience in processing, and meanwhile, the strength of the base layer 1 can be further enhanced due to the fact that the base layer is formed by stacking the plurality of corrugated papers 3; meanwhile, reinforcing nets 6 are arranged among the corrugated paper 3, and the reinforcing nets 6 are reinforced by using the surface tension;
the moisture-proof layer 2 consists of an outer moisture-proof layer 8 and an inner moisture-proof layer 9, a cavity 10 is reserved between the outer moisture-proof layer 8 and the inner moisture-proof layer 9, support frames 11 which are uniformly distributed at equal intervals are arranged in the cavity 10, and the upper end and the lower end of each support frame 11 are fixedly connected with the outer moisture-proof layer 8 and the inner moisture-proof layer 9 respectively;
Preferably, the surface of the corrugated paper core 5 and the upper paper board 15 and the lower paper board 4 are both connected by an adhesive;
preferably, a buffer sponge 12 is placed in the cavity 10, and the buffer sponge 12 can play a role in buffering to counteract the impact force applied to the flat card by the outside due to collision;
