Film coated metal plate with high corrosion resistance, and manufacturing process thereof

Abstract

The invention discloses a film coated metal plate with high corrosion resistance, and a manufacturing process thereof. The film coated metal plate comprises a first corrosion-resistant film layer, a first adhesive layer, a base plate layer, a second adhesive layer and a second corrosion-resistant film layer, wherein the first corrosion-resistant film layer, the first adhesive layer, the base platelayer, the second adhesive layer and the second corrosion-resistant film layer are sequentially arranged from top to bottom, the first corrosion-resistant film layer and the second corrosion-resistant film layer respectively comprise a surface layer, a function layer and an adhesion layer, and the surface layer, the function layer and the adhesion layer are sequentially arranged from top to bottom. The manufacturing process comprises: (1) unwinding; (2) adhesive adding; (3) drying; (4) compounding; and (5) winding. According to the present invention, the film coated metal plate has advantagesof impact resistance, hot water resistance, salt spray resistance, wear resistance, stain resistance, corrosion resistance, light aging resistance, acid resistance, alkali resistance, oil resistance,good flexibility and corrosion resistance, such that the film coated metal plate has long service life; and the process method is simple, and is suitable for mass production.

Description

technical field [0001] The invention relates to a highly corrosion-resistant coated metal plate and a manufacturing process thereof. Background technique [0002] Metal plates are usually used as a building material, widely used in roofs and walls of large public buildings, public factories or integrated houses, etc. However, when color-coated plates are applied to wall panels or roof panels such as chemical plants, the The use environment is relatively harsh, such as strong corrosiveness or humid environment, etc. It is not easy to clean oil stains and other difficult-to-remove stains, especially for acid-base corrosion, which cannot be solved well, thereby reducing its service life; at the same time, the current Some metal plates have a problem of poor corrosion resistance. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a highly corrosion-resistant film-coated metal plate and its manuf...
