[0004] Dyed cardboard is needed in daily life painting, but most of the existing dyed cardboard does not have a flame retardant function, resulting in the situation that the dyed cardboard may lead to a fire, limiting the use of the dyed cardboard and affecting the normal use of the dyed cardboard. At the same time, when the dyed cardboard is used as an album liner or drawing paper, the dyed cardboard may be folded, causing wrinkles and creases left by folding on the surface, affecting the aesthetics; for this reason, we have designed a dyed cardboard. Summary of the Utility Model

[0005] A dyed cardboard provided by an embodiment of this application can solve the technical problems that the cardboard does not have a flame retardant function and that when the dyed cardboard is used as an album liner or drawing paper, it may cause wrinkles on the surface of the dyed cardboard, affecting the aesthetics.

[0006] An embodiment of the present application provides a dyed cardboard, which includes a base layer and a strengthening mechanism. The strengthening mechanism includes an anti-folding layer, a memory support layer, a flame-retardant layer, a top dyed surface layer, and a bottom dyed surface layer. A first adhesive layer is provided on the upper surface of the base layer, and the anti-folding layer is bonded to the first adhesive layer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Based on this, in order to improve the problem that the dyed cardboard in the related art does not have a flame retardant function, resulting in the occurrence of fires caused by the dyed cardboard, limiting the use of the dyed cardboard and affecting its normal use. At the same time, when the dyed cardboard is used as a lining paper for a picture album or drawing paper, it may cause the dyed cardboard to fold, resulting in wrinkles and creases on the surface, affecting the aesthetics, the embodiments of the present application provide the following solutions.

[0023] Please refer to Figures 1 to 4, A dyed cardboard includes a base layer 1, a waterproof coating 7, and a strengthening mechanism 2. The waterproof coating 7 can isolate the bottom layer 25 and the top layer 24 of the dyed surface from water, preventing water from penetrating into its interior and affecting the normal use of the dyed cardboard. The strengthening mechanism 2 is used to make the dyed cardboard not easily fold or bend, thereby preventing creases generated after the dyed cardboard is bent and folded from remaining on the surface of the dyed cardboard and affecting the aesthetics.

[0024] Please refer to Figure 1 and Figure 2 , The flame-retardant layer 23 is bonded to the third adhesive layer 5. The top layer 24 of the dyed surface is bonded and fixed to the flame-retardant layer 23. A fourth adhesive layer 6 is provided on the lower surface of the base layer 1. The dyed bottom layer is bonded and fixed to the fourth adhesive layer 6. Waterproof coatings 7 are bonded and fixed on both the top layer 24 and the bottom layer 25 of the dyed surface, and the waterproof coatings 7 are integrally formed with the top layer 24 and the bottom layer 25 of the dyed surface. The flame-retardant layer 23 is made of tin foil material, and the flame-retardant layer 23 is used in cooperation with the base layer 1. The base layer 1 is made of kraft paper material. The first adhesive layer 3, the second adhesive layer 4, the third adhesive layer 5, and the fourth adhesive layer 6 are made of adhesive material.

[0025] With such a setting, during use, by setting the base layer 1, the first adhesive layer, the second adhesive layer, the flame-retardant layer 23, the bottom layer 25 of the dyed surface, the third adhesive layer, the fourth adhesive layer, and the top layer 24 of the dyed surface to be used in cooperation, their connection becomes more firm. Through the setting of the waterproof coating 7, the bottom layer 25 and the top layer 24 of the dyed surface can be isolated from water, preventing water from penetrating into its interior. By making the base layer 1 of kraft paper material, the strength of the base layer 1 can be increased, preventing the base layer 1 from deforming during use. Through the setting of the flame-retardant layer 23, the base layer 1 can have a flame-retardant effect, preventing the base layer 1 from being ignited, solving the problem that most dyed cardboards on the existing market do not have a flame-retardant function, resulting in the occurrence of fires caused by dyed cardboards, limiting the use of dyed cardboards, and affecting the normal use of dyed cardboards.

[0026] Please refer to Figure 1 and Figure 2 , The memory support layer 22 is arranged in a rhombus shape, the anti-folding layer 21 is arranged in a grid shape. The anti-folding layer 21 is bonded to the first adhesive layer 3. A second adhesive layer 4 is provided on the anti-folding layer 21. The memory support layer 22 is bonded to the second adhesive layer 4. A plurality of bonding particles 8 are evenly arranged on the memory support layer 22.

[0027] With such a setting, by setting the anti-folding layer 21 to cooperate with the base layer 1, the strength of the base layer 1 is further increased, thereby improving the anti-folding property of the base layer 1 and making it difficult for wrinkles to occur on the surface of the dyed cardboard. By setting the memory support layer 22 to cooperate with the base material, when the dyed cardboard is used as the lining paper of a picture album or drawing paper, after the dyed cardboard is bent and folded by the viewer, the creases on the surface of the dyed cardboard can automatically recover, thereby preventing the creases generated after the dyed cardboard is bent and folded from remaining on the surface of the dyed cardboard and affecting the aesthetics.

[0028] As can be seen from the above, the working principle of this application is as follows:

[0029] During use, by setting the base layer 1, the first adhesive layer, the second adhesive layer, the flame retardant layer 23, the bottom layer 25 of the dyed surface, the third adhesive layer, the fourth adhesive layer and the top layer 24 of the dyed surface to cooperate with each other, their connection becomes more firm. Subsequently, through the setting of the waterproof coating 7, the bottom layer 25 of the dyed surface and the top layer 24 of the dyed surface can isolate water sources and prevent water from penetrating into their interior. Since the base layer 1 is made of kraft paper material, the strength of the base layer 1 can be increased to prevent the base layer 1 from deforming during use. And through the setting of the flame retardant layer 23, the base layer 1 can have a flame retardant effect to prevent the base layer 1 from being ignited. By setting the anti-folding layer 21 to cooperate with the base layer 1, the strength of the base layer 1 is further increased, thereby improving the anti-folding property of the base layer 1. By setting the memory support layer 22 to cooperate with the base material, when the dyed cardboard is used as the lining paper of a picture album or drawing paper, after the dyed cardboard is bent and folded by the viewer, the creases on the surface of the dyed cardboard can automatically recover.

[0030] The above are only the preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
