Problems solved by technology

[0006] The common or above-mentioned honeycomb core material has the disadvantage that when the thickness of the core material is large, such as when H is 20mm, it is prone to stress instability, and the height or aperture needs to be reduced, which limits its scope of use.
Secondly, the existing honeycomb core material has weak lateral compression resistance, and is often used in combination with surface layer materials. The lateral pressure is mainly borne by the surface layer, and the thickness and material of the surface layer are required to be high, which reduces the surface material and structural design flexibility
In addition, the different materials of the surface layer and the core layer of the honeycomb composite material often increase the recycling cost, and even make the material unrecyclable

Abstract

The invention belongs to the technical field of preparation of honeycomb core materials, particularly relates to a high-strength plastic honeycomb core material with an inner support, and further relates to a preparation process of the honeycomb core material. The honeycomb core material comprises honeycomb walls and honeycomb grids defined by the honeycomb walls. The honeycomb core material is characterized in that a supporting mechanism made of any one of polyethylene, polypropylene, polyvinyl chloride, polystyrene and modified thermoplastic plastic is arranged in each honeycomb grid; the shape of each supporting mechanism is matched with that of the corresponding honeycomb grid; and the height of the supporting mechanisms is smaller than that of the honeycomb walls. Through the specificprocess, starting from the design of the honeycomb structure, the high-strength plastic honeycomb core material with the inner support is built, stress stability is increased, the dependency of the lateral compressive property on a surface material is reduced, surface design is more flexible, thermoplastic materials consistent with the honeycomb core material are adopted as supporting materials,and the honeycomb core material is more environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of honeycomb core material preparation, and in particular relates to a high-strength plastic honeycomb core material with internal support, and also relates to the preparation process of the above-mentioned honeycomb core material. Background technique [0002] The honeycomb core material is mainly made of paper base, plastic and aluminum materials, and its structure has hexagonal, circular, rhombus and so on. Honeycomb core material is widely used in packaging, construction, automobile and other industrial fields because of its excellent compression resistance and ultra-light structural characteristics. However, when the thickness of the honeycomb core material is large, it is prone to stress instability and the lateral compressive performance is slightly weak. Therefore, when the honeycomb core material is used, protective surface sheets are often added on both sides. However, the increase of the surface...
