The disadvantage is that the overall protection is too poor after stacking during transportation, and people have conducted a lot of research on this.

[0003] For example, the Chinese patent document "Antimicrobial and anti-ultraviolet melamine impregnated paper and its preparation method" with publication number CN110438844B includes a melamine resin layer, a first anti-ultraviolet urea-formaldehyde resin layer, a plain base paper or printed decorative paper, a second anti-ultraviolet urea-formaldehyde resin layer and an antimicrobial and anti-ultraviolet melamine resin layer arranged in sequence from bottom to top, and its preparation method includes the following steps: 1) preparing raw materials; 2) impregnating the plain base paper or printed decorative paper with the anti-ultraviolet urea-formaldehyde resin layer; 3) arranging the melamine resin layer and the antimicrobial and anti-ultraviolet melamine resin layer on both sides of the plain base paper or printed decorative paper treated in step 2). The melamine impregnated paper of the present invention has excellent anti-ultraviolet and antimicrobial and sterilization effects, and the decorative board obtained by gluing it with a substrate is not only wear-resistant, scratch-resistant, acid-alkali-resistant, scalding-resistant, and pollution-resistant, but also not easy to age and fade, has good antimicrobial and antibacterial effects, and has a long service life.

[0004] It can be seen that in the above-mentioned prior art, the impregnated paper is not fully protected when stacked or transported, and damage to its body during stacking or transportation cannot be avoided. Utility Model Content

[0007] According to a further technical solution, a cavity is provided in the protective shell, and the anti-ultraviolet impregnated paper is placed in the cavity.

[0008] According to a further technical solution, the locking assembly includes a plurality of recessed holes arranged in the protective shell, wherein one of the protective shells is also provided with a plurality of through holes, and bolt structures are provided in the recessed holes and through holes to fix the protective shells on the upper and lower sides.

[0009] According to a further technical solution, the bolt structure comprises a bolt and a nut, wherein the bolt and the nut are arranged in the recessed hole, and the nut is threadably connected to the bolt.

[0010] According to a further technical solution, a plurality of threaded holes are arranged on the outer surface of the nut, and fixing bolts are arranged in the through holes. The fixing bolts pass through the through holes and are threadedly matched with the threaded holes.

[0011] The beneficial effects of the utility model are:

[0012] 1. By providing two upper and lower protective shells, the two protective shells are connected and fixed by a locking assembly, so that the stacked anti-ultraviolet impregnated paper can be completely protected by the protective shells and play a light-shielding function.

[0013] Second, by providing a vacuum protective bag, the stacked anti-ultraviolet impregnated paper and protective shell are isolated from the outside world, and have good waterproof function. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In the figure, there are a protective shell 11, a recessed hole 12, a bolt 13, a through hole 14, a threaded hole 15, a nut 16, an anti-ultraviolet impregnated paper 17, a vacuum protective bag 21, and an exhaust check valve 22. DETAILED DESCRIPTION

[0020] like Figure 1-Figure 3As shown, the utility model is described in detail. For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front and back directions mentioned below are Figure 1 The up-down, left-right, front-back directions of the projection relationship are consistent. The utility model provides an anti-ultraviolet and anti-fading impregnated paper, including stacked anti-ultraviolet impregnated paper 17. The anti-ultraviolet impregnated paper 17 is produced by the process in the background technology. The stacked anti-ultraviolet impregnated paper 17 is provided with protective shells 11 on the upper and lower sides. When the protective shells 11 are buckled, the anti-ultraviolet impregnated paper 17 is protected therein. The protective shells 11 are connected and fixed by locking components.

[0021] Advantageously, a cavity is provided in the protective shell 11, and the anti-ultraviolet impregnated paper 17 is stacked and protected by utilizing the cavity.

[0022] Advantageously, the locking assembly includes a plurality of recessed holes 12 disposed in the protective shell 11 , wherein one of the protective shells 11 is further provided with a plurality of through holes 14 , and bolt structures are provided in the recessed holes 12 and the through holes 14 to fix the protective shells 11 on the upper and lower sides.

[0023] Advantageously, the bolt structure includes a bolt 13 and a nut 16 , wherein the bolt 13 is disposed in a recessed hole 12 of one of the protective shells 11 , and the nut 16 is disposed in a recessed hole 12 of another protective shell 11 , and the nut 16 is threadedly connected to the bolt 13 .

[0024] Advantageously, a plurality of threaded holes 15 are provided on the outer surface of the nut 16 , and a fixing bolt is provided in the through hole 14 . The fixing bolt passes through the through hole 14 and is threadably connected with the threaded hole 15 .
