Problems solved by technology

However, when embossing thicker paper, the embossing depth is shallow, the three-dimensional effect is poor, or the embossing depth is large but the strength is poor, which makes the paper easy to tear during use, which seriously affects the quality of the paper product.

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...

Abstract

The invention discloses a multilayer embossed paper, which comprises a paper body, the paper body includes a bottom paper base layer, a middle anti-stretch layer, a top paper base layer and a raised filling layer, and the middle anti-stretch layer is arranged at the bottom The top of the paper base layer, the top paper base layer is arranged on the top of the middle stretch-resistant layer, the raised filling layer is arranged on the top of the top paper base layer, the top of the paper body is provided with pattern grooves, and the raised filling layer includes paper Filling layer and stretch-resistant interlayer, the stretch-resistant interlayer is arranged inside the paper filling layer; the invention also provides a mold for multi-layer embossed paper and a production process for multi-layer embossed paper. The thickness of the paper made by the invention is moderate in the flat position, and the three-dimensionality of the pattern is stronger, and the middle anti-stretch layer and the anti-stretch interlayer are both made of activated carbon fiber cloth and a silicone structural sealant layer, so that the entire paper and the raised The filling layer has high tensile strength and makes the concave part not easy to tear.

Description

technical field [0001] The invention relates to the technical field of multilayer embossed paper, in particular to a multilayer embossed paper and a production process thereof. Background technique [0002] In existing life, paper is usually embossed, which is not only beautiful but also can improve the texture of paper, so that the paper product looks thick as a whole; in the actual embossing process, in order to enhance the thick feeling of paper, The current practice is to realize by increasing the embossing degree of the paper to form higher embossing protrusions on the surface of the paper. However, when embossing thicker paper, the embossing depth is shallow, the three-dimensional effect is poor, or the embossing depth is large but the strength is poor, which makes the paper easy to tear during use, which seriously affects the quality of the paper product. . [0003] Therefore, it is necessary to invent a multi-layer embossed paper and its production process to solve...
