Problems solved by technology

However, this method cannot be transferred to the processing of the surface of color-coated steel sheets, because on the one hand, precious silver resources will be wasted, and the other method is not suitable for mass-produced color-coated steel sheets because it takes a long time. surface processing, on the other hand, it is easy to cause environmental pollution

Embodiment 1

[0027] Take the processing of the specular color coated steel plate shown in the accompanying drawing as an example.

[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 11 on the outward side surface in the use state is uncoiled with an uncoiler, so that the steel coil is unrolled. After uncoiling, the steel strips unfolded on each steel coil are welded head-to-tail by welding, that is to say, the steel strips unfolded on adjacent steel coils are connected to each other to meet the requirements of the subsequent continuous processing process and obtain steel plate to be cleaned;

[0029] B) degreasing cleaning, introducing the steel plate to be cleaned obtained by step A) into a degreasing tank filled with degreasing agent solution for degreasing, in the degreasing tank, the consumption of degreasing agent is 5g / L, the temperature of degreasing agent solution is 70 ℃, steel...

Embodiment 2

[0034]Only change the amount of the degreasing agent in step B) to 5.5g / L, change the temperature of the degreasing agent solution to 75°C, change the water temperature of the washing tank to 75°C; change the drying temperature in step C) to 85 DEG C; Change the thickness of mirror layer 2 in step D) into 50 μ m, the material used in mirror layer 2 changes into the polyurethane coating that adds the nanometer mirror flour that is 20% and particle diameter is 30-50nm by mass percentage, nanometer The mirror flour is nano-silver powder and nano-aluminum powder with a weight ratio of 1:1. The nano-aluminum powder is selected from the brand MH-Al-50 nano-aluminum powder produced by Nanjing Epurui Co., Ltd., Nanjing, Jiangsu Province, China. The speed is 45m / min, the linear speed of the rubber roller is 67.5m / min, the baking temperature of the oven is changed to 230°C, and the hot air drying temperature is changed to 75°C; the thickness of the reflective layer 3 in step E) is change...

Embodiment 3

[0036] Only change the amount of the degreasing agent in step B) to 4.5g / L, change the temperature of the degreasing agent solution to 65°C, change the water temperature of the washing tank to 65°C; change the drying temperature in step C) to 98 ℃; Change the thickness of the mirror layer 2 in step D) into 12 μm, and the material used in the mirror layer 2 changes into a ring that is 40% and the particle diameter is 35-45nm nano-mirror flour that is nano-magnesium powder. Oxygen coating, the travel speed of the steel strip is changed to 120m / min, the linear speed of the rubber roller is changed to 180m / min, the baking temperature is changed to 190°C, and the hot air drying temperature is changed to 65°C; The thickness of 3 is changed to 12 μm, and the material of the reflective layer 3 is changed to a polyvinylidene fluoride coating with a mass percentage of 20% and a particle size of 40-50nm nano-reflective powder. The nano-reflective powder is selected by weight ratio 1: 1 p...

Abstract

The invention provides a mirror surface color coating layer steel plate and a processing method thereof, belonging to the technical field of a color coating layer steel plate. The mirror surface color coating layer steel plate comprises a color coating layer steel base plate, and a color coating layer is arranged on the surface of at least one side of the color coating layer steel base plate. Thecolor coating layer steel plate is characterized in that a mirror surface layer is combined on the color coating layer and a reflecting layer is combined on the surface of the mirror surface layer. As the mirror surface layer and the reflecting layer are combined on the surface of the color coating layer of the color coating layer steel plate in the technical scheme, the color coating layer steelplate has the mirror surface reflecting effect that the mirror surface reflectivity of the color coating layer steel plate against light rays is higher than 75%; therefore, the product grade can be improved, more purposes can be expanded, and the service life of the steel plate can be prolonged as well. With simple processing steps, the provided processing method can meet the industrial requirement for mass production, cannot affect the environment of a processing place, and can ensure comprehensive reflection of the technical effects of the color coating layer steel plate.

Description

technical field [0001] The invention belongs to the technical field of color-coated steel plates, in particular to a specular color-coated steel plate, and also relates to a processing method for the steel plate. Background technique [0002] The steel plate obtained by pre-treating the surface of cold-rolled steel sheet, hot-dip galvanized steel sheet, galvanized steel sheet or aluminum-coated steel sheet, and then coating and color-coating the surface is called color-coated steel sheet, which is customarily called color-coated steel sheet in the industry. , and then called the color plate. Of course, this kind of plate is also called an organic coated steel plate. Since the coatings of various colors on the surface of the colored coated steel plate are pre-coated before the steel plate is processed and formed, it is called a pre-coated steel plate abroad. [0003] The galvanized steel plate is used as the substrate, and the steel plate obtained by coating the color coatin...
