Abstract
The invention relates to an optically variable color coating steel plate and a processing method thereof, belonging to the technical field of color coating steel plates. The steel plate comprises a hot dip galvanizing steel plate. The hot dip galvanizing steel plate is combined with a corrosion-resistant base protection layer towards one inward side under the use state; a set layer is combined on the surface of the base protection layer, and an optically variable light interference layer is combined on the surface of the set layer. The invention provides the technical scheme that the optically variable light interference layer is changed along with the difference of observation angles or the change of light source irradiating angles under the irradiation of light rays, thereby showing a color rendering effect; the recommended processing method has few process steps, is suitable for industrial application and can ensure the prominence of the technical effect of the optically variable color coating steel plates.
Description
Technical field
The invention belongs to the color coating layer steel plate technical field, be specifically related to a kind of optically variable color coating steel plate, and relate to the processing method of this steel plate.
Background technology
The surface (being generally a side surface) that color coated steel plates is based on steel plate applies the organic coating of various different colours and uses and forms coloured coating on the surface of steel plate and name, and industry also abbreviates Coil Coating Products or colored steel as.Use galvanized steel plain sheet as the color coating layer steel plate of substrate except by the protection of zinc layer, also the organic coating layer by the outer aforementioned different colours that applies of zinc layer plays desirable covering buffer action.The steel plate that applies the organic coating layer of different colours outside zinc coat improves more than 50% than promptly anticorrosive, the anti-life-span of getting rusty in the service life of simple galvanized steel plain sheet.Therefore the surface that aforesaid organic coating is coated on galvanized steel plain sheet not only has the steel plate of prolongation service life, and has desirable decoration and sight effect.
Since above-mentioned color coating layer steel plate have lightweight, attractive in appearance, corrosion resistance good and the strong point of easily processing, thereby be widely used in building, the manufacturing of boats and ships, vehicle, household electrical appliances, furniture and electronic electric equipment.But, also there is following shortcoming: although both had the steel plate of prolongation service life at the organic coating layer of the various different pigment of the surface-coated of galvanized steel plain sheet, the effect that has cosmetic decoration again, yet, this organic coating layer does not have peculiar multicolor effect, so-called peculiar multicolor effect is meant under the irradiation of light, difference along with viewing angle, the color of dope layer changes, perhaps viewing angle is constant and change the light source irradiating angle, the color of dope layer changes thereupon, present phenomenon such as red-Huang-green-multiple color swaps such as indigo plant, only this could embody rich texture, gloss is unique graceful and embody value of art appreciation and color rendering effect, and then the purposes of color coating layer steel plate is expanded and use value is able to further lifting.Yet the color coating layer steel plate in the prior art still is not enough to possess this advantage.
In view of this, the applicant thinks, be necessary the color coating layer steel plate in the prior art is done rationally to improve,, the use value of color coating layer steel plate further embodied so that satisfy the pursuit requirement of the decorative effect that people play up unique graceful, the art appreciation of rich texture, gloss and color.For this reason, the applicant retrieves, yet there is no all technology enlightenments of being used for reference that has in disclosed Chinese patent literature and the professional journals.
