Polyvinyl chloride (PVC) plastic steel plate

Abstract

The invention provides a polyvinyl chloride (PVC) composite plastic steel plate. The front face of the steel plate is coated with a passivation layer, an adhesive layer is coated on the surface of the passivation layer, a PVC membrane layer is adhered on the adhesive layer, a protective membrane layer covers on the PVC membrane layer; and the back face of the steel plate is coated with a passivation layer, and a back paint layer is coated on the passivation layer. The invention can play roles of decoration, protection and attraction after the PVC membrane is adhered, has variable colors because the PVC membrane layer can achieve the effect of simulating wood grains, and can be used in industries of home appliances, decoration and the like.

Description

technical field [0001] The invention relates to a steel plate with a layered structure, in particular to a PVC compounded 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.

AI Technical Summary

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
