Embodiment 1
[0028] The present invention provides such Figure 1-4 The multi-layer embossed paper shown includes a paper body 1, and the paper body 1 includes a bottom paper base layer 2, a middle tensile layer 3, a top paper base layer 4 and a raised filling layer 5, and the middle tensile layer The stretch layer 3 is arranged on the top of the bottom paper base layer 2, the top paper base layer 4 is arranged on the top of the middle anti-stretch layer 3, the raised filling layer 5 is arranged on the top of the top paper base layer 4, and the top of the paper body 1 is provided with Pattern groove 6, the raised filling layer 5 includes a paper filling layer 7 and a stretch-resistant interlayer 8, the tensile-resistant interlayer 8 is arranged inside the paper filling layer 7, the bottom paper base layer 2, the top paper base layer 4 And the paper filling layer 7 is made of paper material, and the middle anti-stretch layer 3 and the anti-stretch interlayer 8 are all made of activated carb...
Embodiment 2
[0031] The present invention also provides Figure 1-4 A multi-layer embossed paper mold shown includes a first mold 9 and a second mold 10, the second mold 10 is spaced from the first mold 9, and the top of the first mold 9 and the second mold 10 Both are equipped with a lifting mechanism, and the bottom of the second mold 10 is provided with a first convex plate 11 and a mold groove 12. Groove 6 coincides, and described mold cavity 12 is corresponding to convex filling layer 5, and the top of described convex filling layer 5 is lower than the top of mold groove 12, and the bottom surface of described first mold 9 is arranged as plane and the bottom end is lower than Or parallel to the bottom end surface of the first convex plate 11, so that the first mold 9 surrounds the edge of the pattern groove 6, so that the bottom paper base layer 2, the middle anti-stretch layer 3 and the top paper base layer 4 are pressed against the convex position. Moving inside the mold cavity 12,...
Embodiment 3
[0033] The present invention also provides Figure 1-4 A kind of production technology of multi-layer embossed paper shown, the specific production process steps are as follows:
[0034] Step 1: Prepare the wet paper of the bottom paper base layer 2 and the top paper base layer 4 by pulp, preparation and papermaking processes;
[0035] Step 2: use textile machinery to weave activated carbon fiber cloth, weave different activated carbon fiber cloths according to the thickness of the middle anti-stretch layer 3 and the anti-stretch interlayer 8, and then coat the silicone structural sealant layer on the surface of the textile activated carbon fiber cloth, Obtain the middle anti-stretch layer 3 and the anti-stretch interlayer 8 for subsequent use;
[0036]Step 3: Bond the bottom paper base layer 2, the middle anti-stretch layer 3 and the top paper base layer 4 sequentially from bottom to top, and then press the first mold 9 and the second mold 10 downwards, when the bottom of th...
