Embodiment 1

[0033] like Figure 4 , Image 6 A kind of honeycomb panel shown, comprises the honeycomb core material layer that is formed by a plurality of double-layer composite tubes 1 and the face material layer 9 that is compounded on the upper and lower surfaces of the core material, and the outer layer of the adjacent double-layer composite tube 1 12 are bonded together, and the end faces of the inner layers 11 of adjacent double-layer composite pipes 1 are fused to form glue bumps 71 . The thickness of the glioma 71 is 2 to 10 mm.

[0034] The preparation method of above-mentioned honeycomb plate, comprises the steps:

[0035] 1) Fabricate double-layer composite pipe 1, such as figure 1As shown, the inner layer of the double-layer composite pipe 1 is a high melting point material layer 11, and the outer layer of the double-layer composite pipe 1 is a low melting point material layer 12, and the melting point of the low melting point material layer 12 is lower than the melting poi...

Abstract

The invention discloses a manufacturing method of a cellular board which comprises the following steps of: producing a double-layer composite pipe, wherein the inner layer of the double-layer composite pipe is a high-melting-point material layer, the outer layer of the double-layer composite pipe is a low-melting-point material layer, and the melting point of the low-melting-point material layer is lower than that of the high-melting-point material layer; bundling the multiple double-layer composite pipes in order, heating so that the outer layer of the double-layer composite pipe is melted and the inner layer is not melted and cooling to enable the adjacent attached outer layers of the double-layer composite pipe are bonded together to form a honeycomb; cutting the honeycomb along the cross section of the double-layer composite pipe so as to obtain a platy honeycomb base material; and hot pressing the top surface and the bottom surface of the multiple honeycomb base materials in the same plane so that the end surface of the adjacent attached inner layers of the double-layer composite pipe is fused to form a fillet to obtain the cellular board. The invention also discloses a cellular board manufactured by using the method. According to the technical scheme, the cellular board with stability, evenness, reliable quality, high intensity and large area can be obtained.

Description

technical field [0001] The invention belongs to the field of honeycomb materials, in particular to a honeycomb panel and a preparation method thereof. Background technique [0002] In modern times where resources and energy are becoming more and more scarce, honeycomb material is a very advantageous material, because it has the advantages of light weight and high strength, and can save a lot of raw materials. At present, the relatively mature honeycomb core materials are aluminum honeycomb and paper honeycomb. Aluminum honeycomb has higher strength but higher price and weight, and is mainly used in the aviation field; The thickness of the core cannot be made too thick, and the strength is low, which is mainly used in the packaging field. The honeycomb made of thermoplastic materials has a good improvement in physical properties and greatly improved impact resistance, and thermoplastic materials themselves have the advantages of recyclability, waterproof, corrosion resistanc...
