Embodiment

[0026] Such as figure 1 As shown, a photochromic color-coated steel sheet includes a substrate 10, and the substrate 10 can be a cold-rolled steel sheet, an electro-galvanized steel sheet, a hot-dip galvanized steel sheet, or an galvanized steel sheet. The substrate 10 includes a front and a back, and a layer of chemical coating 20 is provided on the front and back of the substrate 10. The chemical coating 20 on the front of the substrate 10 is provided with a primer layer 30 on the surface of the primer layer 30. A photochromic material layer 40 is provided. A corrosion-resistant paint layer 50 is provided on the surface of the chemical coating 20 located on the back of the substrate 10 .

[0027] In this embodiment, a transparent protective film 60 is provided on the surface of the photochromic material layer 40 . Prevent the top coat from being scratched and polluted during the transportation of the product.

[0028] In this embodiment, the corrosion-resistant paint laye...

Abstract

The invention discloses a light-sensitive color change colored coating steel plate, which comprises a substrate, wherein the substrate comprises a front face and a back face, wherein both the front face and the back face of the substrate are provided with chemical coatings; the surface of the chemical coating positioned on the front face of the substrate is provided with a primary coat; the surface of the primary coat is provided with a light-sensitive color change material layer; the surface of the chemical coating positioned on the back face of the substrate is provided with a corrosion-resistant coating layer; the surface of the light-sensitive color change material layer is provided with a layer of transparent protective film; the corrosion-resistant coating layer is an epoxy coating or a polyurethane coating; and the chemical coating is a chromium-free netlike chemical conversion film, and is 1-2 mu.m in thickness. The invention further discloses a manufacturing method of the light-sensitive color change colored coating steel plate. Due to the design of the primary coat, the flatness of the steel plate is enhanced, and the surface effect is more flat and brighter; due to the design of the light-sensitive color change material layer, the decorating property is enhanced greatly; and due to the design of the corrosion-resistant coating layer, the corrosion resistance of the steel plate is enhanced.

Description

technical field [0001] The invention relates to the technical field of steel plate manufacturing, in particular to a photochromic color-coated steel plate and a manufacturing method thereof. Background technique [0002] The existing color-coated steel sheets are made of cold-rolled steel sheets, electro-galvanized steel sheets, hot-dip galvanized steel sheets or galvanized steel sheets as substrates, after surface degreasing, phosphating, and complex acid treatment, and then coated with organic coatings and baked. finished product. Widely used in construction, home appliances, decoration, automobiles and other fields. With the continuous improvement of people's living standards, people's demand for color-coated steel sheets is becoming more and more high-end and diversified. The surface effect of the existing color-coated steel sheet is poor in flatness, and the single tone or common pattern makes it not very decorative and not corrosion-resistant.
