A kind of edge banding technology of honeycomb panel

Abstract

The invention provides an edge sealing process, which can be applied in common plates, can be particularly applied in honeycomb plates which are of arc-shaped and curved-shaped non-straight shapes and the like on four sides or are of chamfering and round corners on four corners, and comprises steps: a slotting: honeycomb cores which are arranged on the four sides of a honeycomb plate are milled through a milling machine to mill a groove which is 5-15mm in depth; b arranging edge sealing adhesives: epoxy resins and curing agents are uniformly mixed to prepare an edge sealing adhesive according to the radio of 2-3:1; c filling adhesives: the mixed edge sealing adhesive is uniformly filled into the groove which is arranged on the periphery of the honeycomb plate, and the outer surface of the edge sealing adhesive is flatted through a shovel blade; d secondary processing and forming: the edge of sealing edges are finely milled through the milling machine after the edge sealing adhesive is completely solidified, uneven and unsmooth parts of the edges of the sealing edges are milled off, and the edge sealing adhesives on the periphery of the honeycomb plate are secondarily formed and processed simultaneously. The edge sealing process can achieve sealing of complex structured products, and also enables the edge surfaces of finished products to be more smooth and beautiful.

Description

technical field [0001] The invention relates to the technical field of edge sealing of boards, in particular to an edge sealing process of honeycomb boards. Background technique [0002] At present, all panels on the market can be divided into two types from the structural form, one is a solid panel and the other is a hollow panel. As a hollow panel, a honeycomb panel is composed of a panel, a back panel and a honeycomb core. From the structure The watch is composed of faceplates and backplanes placed in parallel and a honeycomb core sandwiched between the faceplates and backplanes. Because of its light weight and high strength, it is widely used in various fields, such as building curtain walls, rail trains, aerospace industry, shipbuilding and other industries. Due to the wide range of applications, the edge banding process of honeycomb panels, especially aluminum honeycomb panels, has always been a research hotspot in this field.

Problems solved by technology

Due to the wide range of applications, the edge banding process of honeycomb panels, especially aluminum honeycomb panels, has always been a research hotspot in this field. The traditional edge banding process mostly uses the method of bending the panel as a whole, but this method is mostly used in right-angle edge banding, which has obvious disadvantages. Limitations, and poor post-processing, can not be secondary molding

In the prior art, foam strips (or edge banding strips) are glued to the edge of the plate and combined with the edge banding surface for edge banding, but the firmness of the paste is not very high, especially for the edge banding of aluminum honeycomb panels. The edge banding surface and even the filled foam strip (or edge banding strip) are easy to be damaged or even fall off after a long time, and the foam strip and edge banding surface need to be prepared separately through the production line, the process is complicated, the production cost is high, and its monomers and degradation products High toxicity, high plasticizer content in PVC, not conducive to environmental protection

[0003] In addition, for the existing edge sealing process, when the four sides of the honeycomb panel are arc-shaped or other shapes or the four corners are chamfered or rounded, the existing edge sealing method cannot be effective
