Environment-friendly nano composite metal plate

Abstract

The invention discloses an environment-friendly nano composite metal plate, which comprises a steel plate, and is characterized in that a back paint layer is arranged on the back face of the steel plate; a bottom paint layer is arranged on the surface of the steel plate; a face paint layer is arranged on the bottom paint layer and is composited with a plastic layer; and the plastic layer is formed by bonding nanoscale PET (polyethylene terephthalate) plastic and a PBT (polybutylece terephthalate) plastic film via a bonding agent and is 22 to 40mum in thickness. The surface of the metal plate disclosed by the invention is composited with the nanoscale plastic layer, so the metal plate has environment-friendly and non-toxic performance, and patterns and colors of the metal plate can be changed according to requirements; and since nanoscale material is adopted, the surface of the metal plate is clean and is not easy to pollute; the metal plate also maintains the protective effect and the decorative effect of the plastic film, so the metal plate has a richer and more colorful appearance and is particularly suitable for being used in the household appliance manufacturing industry.

Description

technical field [0001] The invention relates to an environment-friendly nano-composite metal plate. Background technique [0002] In the prior art, steel plates are widely used in industry and life, such as automobiles, refrigerators, washing machines, high-end furniture, kitchen equipment, industrial and civil buildings, etc., and the surface of ordinary steel plates needs to be coated with a protective layer or decorated It can be used as a formal product after layering, and most of them are made 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 appliances 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 eff...

Problems solved by technology

[0002]In the prior art, steel plates are widely used in industry and life, such as automobiles, refrigerators, washing machines, high-end furniture, kitchen equipment, industrial and civil buildings, etc. In general, the general steel plate can be used as a formal product after being coated with a protective layer or a decorative layer on its surface, and most of them are processed after the product or semi-finished product is made, so it brings a lot of inconvenience to the manufacturer and manufacturer.

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 appliances 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
