Abstract

The present invention relates to metal plate for building, electric appliance casing, etc. and is especially decorative metal material board and its production process. The decorative board is composite structure comprising the first layer of metal base material, the second monochromic layer, the third decorative pattern layer, the fourth protecting layer of light cured resin and the fifth layer of protecting film. Owing to the protecting layer of light cured resin formed through spraying or roller painting, the decorative metal board is beautiful and possesses stereo feeling. The decorative metal board may be produced in required size to avoid waste, the production process has low cost, high efficiency, low power consumption and no environmental pollution.

Description

technical field [0001] The invention belongs to the field of metal plates used in buildings, home appliance shells, etc., and particularly relates to a metal material decorative plate with decorative patterns and a preparation method thereof. Background technique [0002] The metal plates used for construction and home appliance decoration are divided into two types. One type is based on metal plates such as aluminum plates, thin iron plates or thin steel plates with a thickness of 0.2-0.7 cm, and powder coating is sprayed on the surface, or Spray nitro, amino, acrylic, polyester, polyurethane coil steel paint, and bake the metal material decorative plate at a temperature of 80-180 ℃; or cover the metal plate with a color paint layer, a flexible resin layer, an adhesive layer and a transparent resin layer is prepared into a resin-coated metal plate, as disclosed in CN1222881A; this type of metal material decorative plate is used as a decorative materi...
