Problems solved by technology

However, this production process is relatively simple, and can only be coated with one polymer resin, and can only produce double-layer metal composite panels made of a single polymer resin, and the product has a narrow temperature range; The surface of the front steel plate is treated and protected, and the curing reaction process cannot be precisely controlled. The peel strength of the product is generally slightly higher than 50N / cm, and the bonding strength is low.
Other patents disclosed at this stage generally have the problems of long production lines and high investment costs

Abstract

The invention provides a production process of a metal composite plate, and belongs to the technical field of metal plate production. The two layers (upper layer and lower layer) of metal belt materials complete surface cleaning through a surface cleaning machine; for the upper layer metal belt material, a layer of chemical coating liquid is coated on the upper surface by an upper layer chemical coating machine; then, the upper layer metal belt material directly enters a drying furnace to complete the drying treatment; for the lower layer metal belt material, after passing through a lower layer chemical coating machine and a chemical coating drying furnace, a coating machine and a back coating machine are used for respectively coating a layer of liquid-state macromolecular resin and liquid-state environmental-friendly paint on the lower surface and the upper surface; then, the belt material enters an F-shaped drying furnace to complete the drying treatment. The upper and lower layer metal belt materials treated by the F-shaped drying furnace complete the compounding through a compounding machine unit and the curing treatment through a curing machine unit; then, the forced cooling is performed through a forced cooling machine unit; finally, the compounded double-layer metal composite plate is subjected to refining treatment; collection and roll forming are performed. The three-layer structure and the F-shaped drying furnace are used; the production process is simplified; the investment cost and the production cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of metal plate production, and relates to a production process of a metal composite plate. Background technique [0002] In the existing production process of double-layer metal composite plates (see Baosteel's "Production Process of Vibration Damping Composite Steel Plates", the patent publication number is CN1268411A), it is mainly to coat a layer of liquid polymer resin on the surface of a single steel plate, and to The other steel plate is preheated, and then the volatilization and curing reaction of the solvent is completed through the drying furnace and the curing furnace, and the production of the double-layer metal composite plate is completed through operations such as hot rolling and cold rolling. However, this production process is relatively simple, and can only be coated with one polymer resin, and can only produce double-layer metal composite panels made of a single polymer resin, and the produ...
