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. The color 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 steel plate 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
The invention belongs to the color coating layer steel plate technical field, be specifically related to a kind of mirror surface color coating layer steel plate, and relate to the processing method of this steel plate.
Background technology
Pre-treatment is carried out on cold-rolled steel sheet, hot-dip galvanizing sheet steel, aluminum-zinc alloy steel plate or aludip surface, again external coating and the resulting steel plate of color coating are called color coating layer steel plate, the industry custom is called Coil Coating Products, and then is called colored steel.Certainly, it is steel plate with organic coating that this plate of title is also arranged, because the coating of the various different colours on color painted steel strip surface applied before steel plate machine-shaping in advance, therefore, is called precoated steel plate abroad.
With zinc-plated steel plate as substrate; again at the resulting steel plate of surface-coated coloured coating of zinc coat except the protection that the zinc layer is arranged; the organic coating outer by the zinc layer plays the covering buffer action; thereby can play desirable rust inhibition to steel plate; service life is longer than simple galvanized steel plain sheet, can prolong for 50% service life.
Color coating layer steel plate is widely used by building industry, shipbuilding industry, vehicle manufacturing industry, furniture industry and electric utility except having strong point such as lightweight, attractive in appearance and good Corrosion Protection and processability, the strong point that also has, energy savings high for wood, efficiency of construction and prevent to pollute etc. with steel.
But, color coating layer steel plate in the prior art still has shortcoming, promptly owing to do not have mirror effect, thereby can't present bright as if texture like mirror, expansion to the purposes of color coating layer steel plate constitutes restriction, perhaps is difficult to promote the class that adopts the product that color coating layer steel plate makes or decorates and decorate class.
Though the formation method of mirror effect is not that people are strange, usually can be at carrier surface silver-plated or plating mercury, or evaporation of aluminum or silver carry out the mechanical grinding polishing again, thereby obtain mirror effect.But this method can't be diverted to the processing to the color coating layer steel plate surface, because can waste valuable silver-colored resource on the one hand, other method is not suitable for the Surface Machining to the big color coating layer steel plate of production capacity of mass because of length consuming time, causes environmental pollution more on the one hand easily.For this reason, the applicant retrieves, but does not search relevant for making the color coating layer steel plate surface have the technology enlightenment of mirror effect, again, explore for a long time through the applicant, find a way to resolve the problem, technical scheme described below produces under this prerequisite.
