Embodiment 1

[0026] combine Figure 1-5 , This embodiment provides a cardboard core layer structure, which is improved on the basis of the traditional type, and greatly improves the strength of the cardboard. Specifically, the cardboard core structure 100 includes an outer cell 10 and an inner cell 20, the inner cell 20 is fixed in the outer cell 10, and the internal support of the cardboard core structure 100 is optimized to meet high-strength It is required to provide a foundation; the front and rear ends of the inner layer cell 20 are provided with an inner layer extension 21, and the front and rear ends of the outer layer cell 10 are provided with an outer layer extension 11, and both the inner layer extension 21 and the outer layer extension 11 play a role. Undertaking and connecting functions, the inner layer extension 21 and the outer layer extension 11 are fixedly connected, so that the outer layer cells 10 and the inner layer cells 20 are connected as one. The fixed connection me...

Abstract

The invention provides a high-strength honeycomb paperboard and a bonding method thereof. The paperboard comprises outer-layer cell elements and inner-layer cell elements, wherein the inner-layer cell elements are fixed in the corresponding outer-layer cell elements; inner-layer extending portions are arranged at the front end and the rear end of each inner-layer cell element respectively, outer-layer extending portions are arranged at the front end and the rear end of each outer-layer cell element respectively, and the inner-layer extending portions and the outer-layer extending portions are fixedly connected respectively; the cross section of each outer-layer cell element is in a prismatic table shape; the cross section of each inner-layer cell element is triangular; and the continuous high-strength paperboard is formed by bonding through a drum. Compared with a common honeycomb technical method, for the high-strength honeycomb paperboard and the bonding method disclosed by the invention have the advantages that the process change is less, only several glue printing rollers need to be added, production is simple, material selection is reasonable, the compressive strength is high, the production cost is low and the like, can meet the requirements of high-strength paperboards and have good application and popularization values.

Description

technical field [0001] The invention relates to a high-strength honeycomb paperboard and a bonding method thereof, belonging to the technical field of cushioning packaging materials. Background technique [0002] Honeycomb paperboard is a green and environmentally friendly material with light weight, high strength, low material consumption and recyclable utilization. Honeycomb paperboard is made according to the principle of honeycomb structure in nature and is widely used in aerospace, transportation, packaging and construction fields. The improvement of the strength of the honeycomb sandwich panel is of great significance to the related fields of its application. However, improving the strength of honeycomb paperboard by increasing the ration of surface paper and core paper will cause a great consumption of raw materials. Therefore, it is more economical and productive to improve the strength of honeycomb paperboard through structural innovation and design of related suppo...
