Embodiment Construction

[0011] The honeycomb panel includes an upper panel layer and a lower panel layer, and a honeycomb core layer is between the upper panel layer and the lower panel layer. The upper panel layer, the lower panel layer and the honeycomb core layer are all made of polypropylene staple fiber and hemp Fiber is made of raw materials; the production method is: the weight ratio of polypropylene staple fiber and hemp fiber is: 30% or 40% or 50% or 60% or 70%: 70% or 60% or 50% or 40% or 30% , using the air-laid method to make polypropylene staple fibers and hemp fibers into coils or sheets, and then press them into sheets with a press machine at a temperature of 180°C-200°C to make upper and lower panels; Put the coil or sheet made of polypropylene staple fiber and hemp fiber into the honeycomb core mold, press the honeycomb core layer under the temperature of 180°C-200°C with a press, and then press it on the top and bottom of the honeycomb core layer. Bond the upper panel layer and the ...

Abstract

The invention relates to a honeycomb core board used for replacing blockboards and the like, mainly aiming to solve the problems that present blockboards and the like have low strength and low weight ratios. The honeycomb core board comprises upper and lower panel layers and a honeycomb core layer and is characterized in that the upper and lower panel layers and the honeycomb core layer are prepared with polypropylene short fibers and jute fibers as raw materials; a preparation method of the honeycomb core board comprises the following steps of: preparing coiled materials or sheets from the polypropylene short fibers and the jute fibers in a weight ratio of 30-70%:70-30% by adopting an air laying method and preparing the upper and lower panel layers from the panels pressed at 180-200 DEG C; and putting the coiled materials or the sheets into a honeycomb core shaped die to be pressed at 180-200 DEG C to prepare the honeycomb core layer, adhering the upper and lower panel layers to the upper and lower surfaces of the honeycomb core layer and pressing the three layers to prepare the honeycomb core board; cylinders or prisms are arranged on a lower plate of the honeycomb core shaped die and under an upper plate; and the upper and lower panel layers can be also prepared from polymer boards, plywood or nonwovens and the like. The honeycomb core board has the advantages of high strength and high weight ratio.

Description

Technical field: [0001] The invention relates to a board used to replace blockboards for making furniture, door panels, roofs, interior partition boards, suspended ceilings and low-cost movable buildings. Background technique: [0002] At present, blockboards, door panels, roofs, interior partition panels, suspended ceilings, and low-cost movable building panels for making furniture generally have disadvantages such as low strength-to-weight ratio and poor chemical corrosion resistance. Invention content: [0003] The technical problem to be solved by the present invention is to provide a honeycomb panel with high strength-to-weight ratio and strong chemical corrosion resistance. [0004] The honeycomb panel includes an upper panel layer and a lower panel layer, and a honeycomb core layer is between the upper panel layer and the lower panel layer. The upper panel layer, the lower panel layer and the honeycomb core layer are all made of polypropylene staple fiber and hemp ...
