Metal plate to be connected with plastic, manufacturing method and metal strip

Abstract

The invention discloses a metal plate to be connected with plastic, a manufacturing method and a metal strip. The metal plate comprises a metal sheet and a metal interface layer. The metal sheet is provided with a first surface. The metal interface layer is provided with an upper surface and a lower surface formed behind the upper surface. The lower surface is laid corresponding to the first surface, so that the metal interface layer is fixed to the metal sheet. A plurality of holes are formed in the metal interface layer, and the sides, located on the lower surface, of the holes communicate with one another. In this way, the connecting firmness of the metal sheet and a plastic layer can be improved, the process can be simplified, and the manufacturing time can be shortened. The metal strip comprises a long-strip-shaped metal sheet body and a long-strip-shaped metal interface layer body. After connection, the long-strip-shaped metal sheet body and the long-strip-shaped metal interface layer body can be wound into a loop. The invention further provides the manufacturing method for the metal plate.

AI Technical Summary

Problems solved by technology

[0004] However, the prior art used for the bonding of metal sheets and plastics has the following problems. Whether it is electroplating or etching, its processing speed is quite slow and tedious, which is not economical, and the liquid used in electroplating or etching is not suitable for subsequent use. It will also cause serious environmental problems

The holes formed by the chemical etching process are not only small in diameter but also quite shallow in depth, so that the bonding strength between the metal sheet and the plastic cannot be effectively improved, and it can only be used for small-area partial bonding or products with low bonding strength.

Each hole is formed independently. When the plastic enters the hole, it is often unable to be embedded due to poor exhaust, resulting in insufficient bonding force and inability to effectively bond with the metal sheet in a large area.
