Problems solved by technology

Ordinary steel plates need to be coated with a protective layer or a decorative layer on their surface before they can be used as formal products, and most of them are processed after they are made into products or semi-finished products. Therefore, it brings a lot of inconvenience to manufacturers and manufacturers.
Moreover, the service life of the steel plate after painting or spraying is not long, it is easy to rust and corrode, and also affects the appearance of the product
In recent years, in the household appliance industry, plastic films on the surface of steel plates have gradually emerged, which can not only play a protective role, but also have a decorative effect and have a good appearance effect. Unfortunately, plastic films can produce a variety of colors and patterns at the same time. , also covers the original luster of the metal, and loses the unique texture of the metal material

Abstract

The invention provides a polypropylene composite plastic coated steel plate, a passivation layer is coated on the front surface of a steel plate, an adhesive layer is coated on the surface of the passivation layer, a polypropylene film layer is adhered on the adhesive layer, and a protective film layer is covered on the polypropylene film layer; the passivation layer is coated on the back surface of the steel plate, and a back paint layer is coated on the passivation layer; the polypropylene film layer adhesion has decorating, protecting and beautifying effect, by adopting vacuum aluminizing, the polypropylene film layer achieves the stainless steel simulation appearance effect, the color is verified and the polypropylene composite plastic coated steel plate can be used for household and decorating industries.

Description

technical field [0001] The invention relates to a steel plate with a layered structure, in particular to a polypropylene composite steel plate. Background technique [0002] Steel plates are widely used in industry and life, such as automobiles, refrigerators, washing machines, high-end furniture, cabinet equipment, industrial and civil buildings, etc. The general steel plate can be used as a formal product only after its surface is coated with a protective layer or a decorative layer, and most of them are processed after making products or semi-finished products, so it brings a lot of inconvenience to manufacturers and manufacturers. Moreover, the service life of the steel plate after painting or spraying is not long, it is easy to rust and corrode, and also affects the appearance of the product. In recent years, in the household appliance industry, plastic films on the surface of steel plates have gradually emerged, which can not only play a protective role, but also have...
