Abstract

The invention provides a front-rear-surface dual-coated matte panel and a manufacturing method thereof. A composite steel plate comprises a PE (polyethylene) protection film, a matte surface paint coating, a bottom paint coating, a steel plate, a bottom paint coating and a matte surface paint coating which are sequentially distributed from top to bottom and compactly combined with one another. The preparation method of the front-rear-surface dual-coated matte composite steel plate comprises the following steps: coating polyurethane adhesive on the rear surface of the PE electronic film, and curing the polyurethane adhesive to form a first adhesive layer to obtain the PE film; pre-degreasing, degreasing and washing the steel plate, carrying out roll coating on the front surface and the rear surface of the steel plate with a potassium dichromate solution, and respectively forming a chemical treatment layer on the front surface and the rear surface of the steel plate; carrying out roll coating on the front surface and the rear surface of the steel plate with matte polyurethane resin paint, and curing and drying the matte polyurethane resin paint to respectively form a matte surface paint coating on the front surface and the rear surface. Compared with the ordinary composite steel plate, the front-rear-surface dual-coated matte panel produced through the method is better in corrosion resistance both on the front surface and the rear surface and higher in etching resistance.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a front and back double-coated matt panel and a manufacturing method thereof. Background technique [0002] Ordinary steel plates are mainly coated with a protective layer or a decorative layer on the front side, and after these products are made into products or semi-finished products, the performance test on the back side cannot meet the testing requirements, and the color tone on the back side of these products is relatively single. The needs of the market are changing day by day, and the demand for composite steel plates with color coating on both sides is increasing. [0003] Both the front and back sides of the double-coated matt panel are coated with a matt finish on the front and back sides, which makes the appearance of the composite steel plate more attractive than ordinary composite steel plates, and can be more widely used in household appliances and industrial ...
