Description

Technical Field

[0001] The utility model relates to the technical field of packaging materials, in particular to a multi-layer composite environmentally friendly corrugated paperboard. Background Art

[0002] Corrugated cardboard is an important packaging material, widely used in the packaging and transportation of various commodities. With the improvement of environmental awareness and the development of the packaging industry, the application prospects of corrugated cardboard will be broader.

[0003] The patent publication number CN220180343U discloses an environmentally friendly corrugated cardboard. The strength of the corrugated cardboard can be enhanced by a reinforcing board layer arranged in the corrugated inner core. After the corrugated cardboard is used, the front cardboard and the rear cardboard are torn off, so that the corrugated inner core can be taken out and reused, thereby achieving energy-saving and environmental protection effects. The pressure-relief component can ensure a stable connection between the reinforcing board layer and the front cardboard and the rear cardboard, and can greatly improve the elasticity and recovery ability of the corrugated cardboard, thereby preventing deformation.

[0004] When the environmentally friendly corrugated cardboard is worn out during use and cannot be used any more, the worn corrugated cardboard will be recycled, but the corrugated inner core cannot be put into the crusher together with the cardboard, and the cardboard bonded to the two sides of the corrugated inner core needs to be torn off manually. When the cardboard is separated from the corrugated inner core, there will be cardboard residue at the bonding point between the cardboard and the corrugated inner core, so part of the cardboard cannot be recycled, resulting in material loss and reducing the utilization rate of the corrugated cardboard.

[0005] In addition, due to its low cost, easy processing and transportation, corrugated cardboard can be spliced ​​into floor mats for temporary activities or exhibition venues. When the above-mentioned environmentally friendly corrugated cardboards are spliced ​​together, there are no connectors at the joints, so the joints of the corrugated cardboards are not firmly connected, causing the corrugated cardboard to tear and break during use, shortening its service life.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a multi-layer composite environmentally friendly corrugated paperboard, the multi-layer composite environmentally friendly corrugated paperboard comprises a paperboard body 1, a connecting component 2 is bonded to one end of the paperboard body, a clamping component 3 is bonded to one end of the paperboard body 1 away from the connecting component 2, the paperboard body 1 comprises a core paper layer 11 and a surface layer 12, the core paper layer 11 is wavy, the core paper layer 11 is arranged between two surface layers 12, the core paper layer 11 is bonded to the surface layer 12, the surface layer 12 comprises a protective layer 121, a honeycomb layer 122, the protective layer 121 is bonded to the honeycomb layer 122. The surface of the protective layer 121 is coated with rubber oil. The protective layer 121 is soaked with rubber oil, thereby increasing the waterproofness and toughness of the paperboard body 1, thereby protecting the paperboard body 1 and improving the wear resistance of the paperboard body 1. The honeycomb layer 122 is composed of a plurality of corrugated plates bonded together and is in a honeycomb shape. The honeycomb grid structure is used to disperse the external force on the paperboard body 1. Buffer components 111 are sequentially arranged on both sides of the core paper layer 11, and the buffer components 111 are arranged on the slope of the core paper layer 11.

[0031] The buffer components 111 are composed of a plurality of supporting paperboards, which are arranged in parallel with each other. The supporting paperboards on two adjacent buffer components 111 are arranged in parallel with each other. The buffer components 111 are arranged in groups of two, and the supporting paperboards on two adjacent groups of buffer components 111 are arranged symmetrically with each other.

[0032] During use, the protective layer 121 enhances the waterproof performance and wear resistance of the paperboard body 1. When external force is applied to the paperboard body 1, the honeycomb grid structure of the honeycomb layer 122 evenly disperses the external force to the surface of the paperboard body 1, thereby enhancing the compression resistance and load-bearing capacity of the paperboard body 1.

[0033] When the cardboard body 1 is compressed under the action of external force, the supporting cardboards on the two adjacent groups of buffer components 111 are symmetrically arranged to form a triangular structure, thereby absorbing the external force applied to the cardboard body 1 and supporting the cardboard body 1. When the external force applied to the cardboard body 1 disappears, the supporting cardboards can act on the cardboard body 1 to restore.
