Edge sealing method for composite board

Abstract

An edge sealing method for a composite board belongs to the technical field of board processing, and comprises the following steps: heating and melting heating type resin, coating the resin on the side edge of the composite board, and shaping after the resin is cooled to form a sealed edge, or coating reaction type resin on the side edge of the composite board, and shaping after the resin is solidified to form the sealed edge. According to the edge sealing device, the edge of a thin composite board can be sealed, the edge of a thick composite board can also be sealed, meanwhile, the edge of a hole formed in the middle of the composite board or the edge of a model cut in the middle of the composite board can be sealed, and the problem that the edge of the thin composite board cannot be sealed through an original skin is solved.

Description

Technical Field

[0001] This invention belongs to the field of sheet metal processing technology, and specifically relates to a method for edge banding composite panels. Background Technology

[0002] CN120620656A discloses "A method for sealing the edges of a composite board", such as Figure 1 As shown, the technical solution is to remove or melt the side of the core material A of the composite board by mechanical means, and roll the side of the upper and lower skins B inward to seal the edges.

[0003] This edge-sealing method is suitable for thicker composite boards. When the composite board is relatively thin, the sides of the upper and lower skins cannot be rolled inward for edge sealing. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the technical solution of CN120620656A cannot seal the edges of thin composite boards, and to provide a method for sealing the edges of composite boards. This method can seal the edges of both thin and thick composite boards, and can also seal the edges of the composite board with openings in the middle or the edges of the shapes cut out in the middle of the composite board.

[0005] A method for sealing the edges of a composite board, comprising: heating and melting a heat-sensitive resin and applying it to the side of the composite board; the resin then cooling and solidifying to form an edge seal; or applying a reactive resin to the side of the composite board and solidifying to form an edge seal.

[0006] After the resin is set to form the edge seal, the edge seal surface is processed to form a smooth surface.

[0007] The edge sealing is either a straight edge or an arc edge.

[0008] The heating type resin is PP resin, PE resin, or EVA resin, etc.

[0009] The reactive resin is polyurethane, PUR adhesive, or silicone adhesive, etc.

[0010] Beneficial technical effects of the present invention: This invention can seal the edges of both thin and thick composite boards, and can also seal the edges of holes or shapes cut out in the middle of composite boards. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the edge sealing structure for CN120620656A; Figure 2 This is a schematic diagram of the edge sealing structure of the present invention. Figure 1 ; Figure 3 This is a schematic diagram of the edge sealing structure of the present invention. Figure 2 ; Detailed Implementation A method for edge banding composite panels, such as Figure 2 and Figure 3 As shown, the composite board consists of an upper and lower skin (B) with a core material (A) filled with foam or a honeycomb structure in between, which is then hot-melted and pressed together. The method is as follows: The heated resin is melted and applied to the side of the composite board. After the resin cools, it sets to form the edge seal C. Alternatively, the reactive resin is applied to the side of the composite board. After the resin solidifies, it sets to form the edge seal C.

[0012] After the resin is set to form the edge seal C, the surface of the edge seal C is processed to form a smooth surface.

[0013] The edge sealing C is as follows Figure 2 The straight edge shown, or as shown in the figure Figure 3 The curved edge shown.

[0014] The heating type resin is PP resin, PE resin, or EVA resin, etc.

[0015] The reactive resin is polyurethane, PUR adhesive, or silicone adhesive, etc.
