Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0024] This application embodiment discloses a flame retardant corrugated board, please refer to Figures 1 - 3, a flame-retardant corrugated board, comprising: a spring shock-absorbing paper 1, the spring shock-absorbing paper 1 is a wavy paper shell, both ends of the spring shock-absorbing paper 1 are bonded with thin cardboard 2, and compression-resistant components 3 are arranged on the outer sides of the two thin cardboard 2s for resisting external pressure, and outer components 4 are arranged on the outer sides of the two compression-resistant components 3 for protecting the compression-resistant components 3. The elasticity of the corrugated paper itself is increased through the spring shock-absorbing paper 1, the impact force received by the corrugated paper itself is reduced, and at the same time, through the elasticity of the spring shock-absorbing paper 1, the buffering performance of the corrugated paper is improved, and the external pressure on the corrugated paper is reduced.

[0025] Please refer to Figures 2 - 4 , the compression-resistant component 3 includes a plurality of first bonding plates 301 bonded to the outer wall of the outer side of the thin cardboard 2, the plurality of first bonding plates 301 are horizontally and equidistantly distributed on the outer side of the thin cardboard 2, and a plurality of support bars 302 are bonded to the outer wall of the outer side of each first bonding plate 301, the plurality of support bars 302 are horizontally and equidistantly distributed at the top of the first bonding plate 301. The compression-resistant component 3 further includes a second bonding plate 303 bonded to the outer wall of the outer side of the plurality of support bars 302, the number of the second bonding plates 303 is the same as that of the first bonding plates 301 and they correspond one by one. The compression-resistant component 3 further includes a semi-enclosed isosceles trapezoidal cardboard 304 arranged outside each second bonding plate 303. The compression-resistant component 3 further includes a third bonding plate 305 bonded to the inner walls of the left and right sides of each semi-enclosed isosceles trapezoidal cardboard 304, and each third bonding plate 305 is bonded to the outer side of the thin cardboard 2. The semi-enclosed isosceles trapezoidal cardboard 304s at both ends of the spring shock-absorbing paper 1 are combined into an approximately isosceles hexagon. The stability of the structure of the corrugated paper is increased through the semi-enclosed isosceles trapezoidal cardboard 304 and the thin cardboard 2, thereby increasing the compression resistance of the corrugated paper. Then, the semi-enclosed isosceles trapezoidal cardboard 304 is supported by the plurality of support bars 302, the supporting force of the semi-enclosed isosceles trapezoidal cardboard 304 is increased, thereby increasing the stability of the semi-enclosed isosceles trapezoidal cardboard 304, thereby improving the supporting strength of the semi-enclosed isosceles trapezoidal cardboard 304, further improving the compression resistance of the corrugated paper, and thereby reducing the possibility of deformation of the corrugated paper.

[0026] Please refer to Figures 2 - 5, the outer component 4 includes an outer cladding 401 adhered to the outside of several semi-enclosed isosceles trapezoidal cardboard sheets 304. The outside of the outer cladding 401 is coated with a heat-insulating coating. The outer component 4 also includes an inner lining paper 402 adhered to the outer wall of the outside of the outer cladding 401. An outer cardboard 403 is adhered to the outer wall of the outside of the inner lining paper 402. The outer component 4 also includes a flame-retardant coating 404 adhered to the outside of the outer cardboard 403.

At the same time, the outside of the outer cladding 401 is coated with a heat-insulating coating to protect the objects inside the corrugated paper and reduce the phenomenon that the objects inside the corrugated paper box are damaged by freezing during transportation in cold weather. Through the double protection of the outer cardboard 403 soaked in the flame-retardant liquid and the flame-retardant coating 404, the damage inside the corrugated paper is further reduced, and the integrity of the objects inside the corrugated paper packaging is further increased.

[0027] Working principle and usage process: First, soak the outer cardboard 403 in the flame-retardant liquid for pretreatment, then coat the outside of the outer cardboard 403 with the flame-retardant coating 404. After the flame-retardant coating 404 is completely adhered, coat the waterproof coating 405 on the outside of the flame-retardant coating 404 and dry it. After drying is completed, it can be used. When the corrugated paper encounters a fire, the outermost flame-retardant coating 404 retards the fire and reduces the fire from further entering the inside of the corrugated paper. When the fire is large, the outer cardboard 403 soaked in the flame-retardant liquid further retards the fire, thereby further improving the flame-retardant performance of the corrugated paper through secondary fire retardation.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
