DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] In order to facilitate the addition of compression reinforcement mechanism, further improve the use strength and compression performance of double corrugated paper core, thereby improving the use effect, such as Figures 1-3 As shown, a double corrugated paper core described in the utility model comprises a first corrugated layer 1, a reinforcing layer 3 and an anti-slip layer 7, wherein a second corrugated layer 2 is arranged on the top of the first corrugated layer 1, the reinforcing layer 3 is connected between the first corrugated layer 1 and the second corrugated layer 2 by gluing, a support column 4 is arranged in the reinforcing layer 3, and both ends of the support column 4 penetrate the reinforcing layer 3 and are respectively connected to the first corrugated layer 1 and the second corrugated layer 2 by gluing;

[0031] A hollow groove 301 is formed in the reinforcing layer 3 , and the hollow groove 301 is filled with a flame retardant 302 .

[0032] When in use, through the reinforcement layer 3, the support column 4, the hollow groove 301 and the flame retardant 302, elastic deformation can be utilized to increase the compression and impact resistance of the double corrugated paper core, making it less susceptible to deformation by external forces, thereby improving the use strength of the first corrugated layer 1 and the second corrugated layer 2, and also increasing the auxiliary flame retardant function.

[0033] In order to improve the functionality and flexibility of use, exemplary, such as Figure 1 , Figure 4 As shown, the utility model also includes that the anti-slip layer 7 is made of epoxy resin anti-slip coating, and the anti-slip layer 7 includes a release film 701.

[0034] When in use, the anti-slip layer 7 and the release film 701 can selectively increase the anti-slip performance of the double corrugated paper core, thereby improving the functionality and flexibility of use.

[0035] Exemplarily, as Figure 1 shown, the present utility model further includes that the reinforcing layer 3 and the support columns 4 are both made of rubber.

[0036] When in use, due to the rubber materials of the reinforcing layer 3 and the support columns 4, it is convenient to utilize elastic deformation to increase the compressive performance of the double corrugated paper core.

[0037] Exemplarily, as Figure 2 shown, the present utility model further includes that a desiccant 401 is filled in the support column 4, and micropores 402 are formed on the surface of the support column 4.

[0038] When in use, through the desiccant 401 and the micropores 402, it is convenient to improve the drying effect of the first corrugated layer 1 and the second corrugated layer 2 and extend the service life.

[0039] Exemplarily, as Figure 1 shown, the present utility model further includes that a first panel 5 is adhesively connected to the bottom of the first corrugated layer 1, and a second panel 6 is adhesively connected to the top of the second corrugated layer 2.

[0040] When in use, through the first panel 5 and the second panel 6, it is convenient to connect the first corrugated layer 1 and the second panel 6.

[0041] Exemplarily, as Figure 1 shown, the present utility model further includes that waterproof layers 8 are adhesively connected to the outer surfaces of the first panel 5 and the second panel 6, and an anti-slip layer 7 is coated on the outer surface of the waterproof layer 8.

[0042] When in use, the waterproof layer 8 is a PET film.

[0043] Exemplarily, as Figure 1 shown, the present utility model further includes that drying layers 9 are provided between the first corrugated layer 1 and the first panel 5 and between the second corrugated layer 2 and the second panel 6.

[0044] When in use, the drying layer 8 is an activated carbon plate.

[0045] When the present utility model is in use, through the first corrugated layer 1 and the second corrugated layer 2 arranged in parallel, when the double corrugated paper core is deformed under external impact, the corrugated paper cores can be mutually clamped. At the same time, under the elastic support of the reinforcing layer 3 and the support columns 4, the deformation generated by the corrugated paper core is reduced. It can not only improve the service strength of the double corrugated paper core, but also is less likely to cause damage to the corrugated paper core. Moreover, through the flame retardant 302 filled in the hollow groove 301 of the reinforcing layer 3, it can play a certain auxiliary flame retardant effect, thereby increasing the functionality and practicality of the double corrugated paper core;

[0046] During the actual use of the double corrugated paper core, according to the use environment, when anti-slip is required, the release film 701 can be separated from the anti-slip layer 7, so as to utilize the anti-slip layer 7 made of epoxy resin anti-slip coating to increase the wear-resistant and anti-slip effect of the double corrugated paper core, thereby improving the use effect.
