Embodiment 1

[0027] As shown in the accompanying drawings, a chameleon colored coated steel plate comprises a colored coated steel plate substrate 1 with a colored coated layer 5 on at least one side of the surface, the colored coated layer 5 includes a color shielding layer 2, an angle-dependent Heterochromic layer 3 , the angle-dependent heterochromatic layer 3 is disposed on the color-shielding layer 2 , and an optical interference layer 4 is disposed on the surface of the angle-dependent heterochromatic layer 3 . The steps of its processing method are:

[0028] A) Uncoiling and docking, the color-coated steel plate substrate 1 that is in the steel coil state and has been coated with the color coating layer 5 on the outward side surface in the use state is uncoiled with an uncoiler, so that the steel coil is unrolled. Steel plates, after uncoiling, use welding to carry out end-to-end welding of the steel plates unrolled on each steel coil, that is to say, connect the steel plates unroll...

Abstract

The invention discloses a chameleonic colored coating steel plate which comprises a colored coating steel plate baseplate (1) with a colored coating (5) arranged on the surface of at least one side, wherein the colored coating (5) comprises a color masking layer (2) and an angle-dependent discoloring layer (3); the angle-dependent discoloring layer (3) is arranged on the color masking layer (2), and a light interference layer (4) is arranged on the surface of the angle-dependent discoloring layer (3). The machining method of the chameleonic colored coating steel plate comprises the following steps of: (A) uncoiling and butting to obtain a steel plate to be washed; (B) degreasing and washing; (C) carrying out passivating treatment; (D) coating the color masking layer; (E) coating the angle-dependent discoloring layer; and (F) coating the light interference layer. The colored coating steel plate has an angle-dependent discoloring reflection effect on lights with different colors along with the angle change, promotes the grade of the product, expands the anti-counterfeiting purpose and prolongs the service life of the steel plate; and the provided machining method has concise steps, can satisfy the industrial batch production requirements and has no influences on machining occasion environment.

Description

technical field [0001] The invention relates to a color-coated steel plate, and also relates to a processing method of the steel plate, belonging to the technical field of the color-coated steel plate. Background technique [0002] Coating organic paint on the steel plate, the paint can have various colors, color-coated steel plate gets its name from this, referred to as color plate, also known as organic coated steel plate. Also because the color-coated steel plate is coated with paint before the steel plate is processed and formed, it is also called pre-coated steel plate abroad. The color-coated steel plate using galvanized steel plate as the substrate, in addition to the zinc protection, the organic coating on the zinc layer plays a role of covering and isolation, which can prevent the steel plate from rusting, and the service life is longer than that of galvanized steel plate. According to the introduction, the coating The service life of steel plate is 50% longer than...
