The non-glue honeycomb board has the characteristics of small density, high rigidity, good stability and excellent sound and heat insulation performance, has the advantages of zero formaldehyde, high temperature resistance, fire resistance and durability, and is more and more concerned by the market.

But the method is limited by the production process, so that the batch and industrial development cannot be realized. The main technical difficulty is the manufacture of the honeycomb core. The existing public data show that the production efficiency is underground, and the manufacturing cost is high; or the product quality is difficult to ensure and the product performance is low due to the limitation of the manufacturing process. As disclosed in "design and manufacture of honeycomb welding construction" document, a metal foil is formed first, and then a tool and fixture combination brazing method is adopted. The method has low production efficiency and is difficult to realize low-cost batch production. As the process of first coating solder at intervals and then brazing as mentioned in the patent with application number 201310003242.1, the problem of overflow after the solder is dissolved is not solved, and the process is difficult to be made into a honeycomb structure; the aluminum foil is first made into honeycomb by using an adhesive as mentioned in the patent application No. 201710847970.9, and then the steps of removing the adhesive and soldering are performed. Because the adhesive is basically remained in the original position (soldering zone) after carbonization in the adhesive removing process and is difficult to remove, large-area cold joint is easy to occur after soldering, and the shearing strength of the honeycomb core is poor.
