Embodiment 1

[0042] The invention provides an anti-contamination invisible color-coated plate, which comprises a top coat layer, an undercoat layer, a first passivation layer, a substrate, a second passivation layer and a back coat layer which are sequentially stacked.

[0043] Wherein, the substrate is a cold-rolled steel plate with a thickness of 0.3mm.

[0044] The first passivation layer and the second passivation layer are arranged on the two surfaces of the substrate respectively, and the two materials are the same, including 11.5 parts by weight of nano-silicon dioxide, 13.5 parts by weight of nano-alumina, 15 parts by weight of titanium dioxide, polyamide 65 parts by weight. The first passivation layer and the second passivation layer are cross-linked and passivated by titanium dioxide and polyurethane, and by adding synergistic slow-release factors nano-silicon dioxide and nano-alumina, the first passivation layer and the second passivation layer are effectively improved. Corrosi...

Abstract

The invention belongs to the technical field of materials, and particularly relates to an anti-contamination invisible color-coated board and a preparation method thereof. The color-coated board comprises a top coating layer, bottom coating layer, first passivation layer, substrate, second passivation layer and back coating layer which are sequentially laminated; wherein, in the top coating layer,2-ethyl-2-butyl-1, 3-propanediol is matched with 2-bromine-2-nitropropane-1, 3-glycol to improve the roughness of the surface of the top coating layer, the hydrophobic performance of the top coatinglayer is improved and the stain resistance of the color-coated board is improved; nano titanium dioxide can catalyze and decompose pollutants such as organic matters and the like on the surface of thetop coating layer, and the addition of wollastonite powder can enhance the catalytic property of the nano titanium dioxide and further improve the stain resistance of the top coating layer. The top coating layer also comprises a hollow microsphere/carbon nano tube/epoxy resin and silicon carbide/carbon fiber composite material to achieve the invisible function of the color-coated board. In addition, the color-coated board has higher strength and weather resistance, the preparation method is simple, and the color-coated board is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to an anti-contamination invisible color-coated plate and a preparation method thereof. Background technique [0002] Color-coated steel plate is color-coated steel plate, which is based on cold-rolled steel plate or galvanized steel plate. Products made by cooling. As a new type of material with bright colors, convenient processing and low cost, color-coated panels are widely used in construction, shipbuilding, home appliances, decoration, transportation and other fields. [0003] In recent years, the application range of color-coated panels has expanded to the military field, such as base exterior walls and equipment and facilities. Such color-coated panels require a certain camouflage effect, and camouflage color-coated panels have emerged as the times require. The texture and color of the camouflage color coating fully draws on the standard color of military camo...
