Problems solved by technology

Due to a certain demoulding slope, the honeycomb structure is mostly non-hexagonal (mostly circular), and cannot be densely packed on the diameter stick surface, and its strength is worse than that of hexagonal; at the same time, it is difficult to realize deep hole cavity , which limits the thickness of the product; the plate is not flat when the upper and lower layers are combined, which affects the flatness and physical properties of the product; the honeycomb holes are not transparent, causing material waste when the panel is adhered to the bottom

Abstract

The invention discloses a production method for a plastic cellular board. The production method includes the following steps that firstly, a plastic cellular core raw material is extruded through an extrusion die of an extruder; secondly, the plastic cellular core raw material is cooled and shaped; thirdly, the outer wall of the plastic cellular core raw material is pressed, so that the plastic cellular core raw material is pressed into a plastic cellular piece; fourthly, the plastic cellular piece is cut in a fixed-length mode, so that a series of plastic cellular strips are formed; fifthly, the upper surface of the i plastic cellular strip and the lower surface of the (i+1) plastic cellular strip are bonded, or the lower surface of the i plastic cellular strip and the upper surface of the (i+1) plastic cellular strip are bonded, so that a plastic cellular core block is formed through bonding, wherein i is a natural number; sixthly, the plastic cellular core block is stretched to form a plastic cellular core; and seventhly, an upper panel and a lower panel are bonded to the plastic cellular core, so that the plastic cellular board is formed.

Description

technical field [0001] The invention relates to the technical field of plastic honeycomb panels, in particular to a production method of plastic honeycomb panels. Background technique [0002] The honeycomb panel is composed of two panels and a honeycomb core. The design idea of ​​the honeycomb panel structure comes from the I-beam structure: the panel is equivalent to the wing plate of the I-beam, which mainly bears normal stress; the honeycomb core is equivalent to the web of the I-beam, Mainly bear the shear stress. The structural strength of the two panels is large, and there is a large section moment of inertia, so the rigidity is good and the bending strength is large. [0003] Honeycomb panels are generally divided into two categories: metal and non-metal. Metal honeycomb panels are mainly used in aircraft manufacturing, automobile manufacturing, shipbuilding, transportation, etc. Non-metallic honeycomb panels are further divided into fiber and paper. Fiber honeyc...
