Description

Process for preparing preprocessed honey comb panel

The present invention relates to a pre-processed honeycomb core composite panel, and in particular, the upper heat-melting adhesive film, the honeycomb core, the lower heat-melting adhesive film and the other flat plate in a bending box in which one of the upper and lower plates bent in a box shape The prefabricated honeycomb core composite panel is characterized in that it is thermocompressed by hot pressing after being embedded.

In general, a honeycomb core composite panel (hereinafter referred to as a honeycomb composite panel) includes a honeycomb core 40 and a top and bottom flat plate 10 and 10 'at the center thereof as shown in FIG. The honeycomb panel is manufactured by bonding the thermal melting adhesive films 20 and 20 'embedded in between the 10' and the honeycomb core 40 to produce honeycomb panels. The raw materials such as aluminum, steel, galvanized steel sheet, hot melt adhesive film and honeycomb cores are cut to the same size by manual labor, stacked one by one, put into hot press, and hot pressed to produce honeycomb composite panel. Since it is difficult to cut each raw material to the same size, it is not accurate, and even if it is hardly cut to the same size, even when it is inserted into a hot press or moved, and it is heated, pressed and cooled. Since in each layer become easy each skewed it is neatly stacked with the sides coinciding extremely difficult.

Therefore, the honeycomb composite panel manufactured in this way must be shipped after cutting the side smoothly after manufacturing, which makes the process complicated and the working time becomes long. Therefore, it is difficult to mass-produce in a short time and requires a lot of manpower. This was a factor of material loss and cost increase.

The present invention provides a box-shaped one of the honeycomb core, the adhesive film and the upper and lower plates in the form of a box in order to solve the defects such as manufacturing defects, defect rate and scrap loss in the production of the conventional honeycomb panel as described above. It provides a method for manufacturing a honeycomb composite panel without thermal cutting and pressing of the edges and the panel bending after pressing in a fixed state after the pre-processing, and will be described in detail with reference to the accompanying drawings.

In order to achieve the object as described above, the present invention incorporates an upper and lower heat-melting adhesive film (2) (2 ') between the center honeycomb core (4) and the upper and lower plates (1) (1'). In the method for manufacturing a honeycomb composite panel, as shown in Fig. 1, the flat plate 1 on either side of the top and bottom flat plates 1 and 1 'is bent in a predetermined width in all directions. After finishing the corner (corner) (5) to make a quadrangular bending box (3), and the same size as the inner surface of the bending box (3) hot melt adhesive film (2) (2 ') and honeycomb core (4) and the other plate (1 ') of the other side is cut and laminated in turn in the bending box (3), and then thermally compressed in a hot press to produce a honeycomb composite panel that does not require a separate post-process.

As a method of finishing the four corners (corners) 5 by bending all the above, as shown in FIGS. 2A and 2B, the upper flat plate 1 and the corners 5 have a square shape 6. Alternatively, as shown in Fig. 3 (a) (b), as shown in Fig. 4 (a) (b) or an isosceles triangular shape 7 in which the bend line 9 and height 10 coincide. Likewise, the square shape (8) and then take the form of any one of the shape formed in the incision line 11 in the W-shape, then bend it to finish it. ), And in case of dividing into an isosceles triangle, the bend after joining becomes oblique (13) and the square shape (8) is taken out and then cut into a W-shaped cut line (11). After the joint is finished to the Y-shaped (14).

By manufacturing the honeycomb composite panel pre-processed in the above manner, the honeycomb core 4 of the same standard, the hot melt adhesive film (2) (2 ') and the lower plate (1') is a four-sided bending box ( 3) Because it is naturally and neatly stacked without distortion or scattering in the inside, thermocompression bonding is easy and accurate, and thus there is no defect rate, and the honeycomb composite panel manufactured in this way is neat and smooth in four sides. As a result, the building has the advantage of not having to bend the four sides separately during construction.

In the honeycomb composite panel according to the present invention, the honeycomb core (4), the hot melt adhesive film (2) (2 ') and the lower plate (1') is a bend box (3) bent in four corners to a certain standard Since it is thermocompressed by hot press while being embedded in the product, there is an effect that a large quantity of high quality pre-processed honeycomb composite panel can be produced in a short time without generating defective products or scraps.
