Noctilucent color coated layer steel plate and manufacturing method thereof

Abstract

The invention discloses a noctilucent color coated layer steel plate and a manufacturing method thereof, belonging to the field of color coated layer steel plates. The steel plate comprises a steel plate substrate, a primer paint coating, a finish paint coating and a noctilucent layer, wherein a chemical coating is formed at the surface at one side of the steel plate substrate facing toward the primer paint coating; the primer paint coating is bonded at the surface of the chemical coating; the finish paint coating is bonded at the surface of the primer paint layer; and the noctilucent layer is bonded at the surface of the finish paint coating. The manufacturing method comprises the following steps of: selecting a zinc coated or aluminum coated steel plate, washing, drying, carrying out chemical coating on the surface of one side of the steel plate substrate so as to form the coatings, coating the primer paint on the surface of the coatings and drying, cooling and coating the finish paint on the surface of the primer paint coating, drying, cooling the finish paint coating, and subsequently coating noctilucent materials on the surface of the finish paint coating. The steel plate has the effects that the noctilucent layer is enhanced to absorb the natural light; good light emission brightness in dark is obtained; the bonding effect of the primer paint coating is guaranteed; the service life is not influenced by desquamation; the process procedures are simple; and the requirements on industrial production expansion are met.

Description

technical field [0001] The invention belongs to the technical field of color-coated steel plates, in particular to a luminous color-coated steel plate, and also relates to a preparation method of the luminous color-coated steel plate. Background technique [0002] In public places, such as the lights on the floors of buildings, the lights are always on all night. Although it can play a positive role in preventing pedestrians from falling and even preventing theft, it is an undoubted fact that it causes waste of electric energy. Again, in the event of a power outage, damaged lamps, and / or a person maliciously turning off the power, the danger is self-evident. [0003] If traffic signs, stair handrails, emergency evacuation passages and even leisure and entertainment places (such as tea bars, coffee bars) can absorb natural light during the day and emit light at night, it is an extreme energy-saving measure. [0004] The technical information of luminous boards with non-pure ...

AI Technical Summary

Problems solved by technology

[0006] Although the above-mentioned CN101544155A and CN101544156A can embody the technical effects recorded in their instructions, they have the following disadvantages: First, because the luminous layer (also known as the luminous layer) is arranged on the Between the surface and the primer coating, therefore, the topcoat coating affects the absorption of natural light by the luminous layer (ie, the luminous coating) to a certain extent, that is, affects the effect of the luminous layer on absorbing natural light; secondly, because the luminous layer is in the dark When the natural light is emitted in the medium, it is covered by the topcoat, which affects its luminous effect; thirdly, the bonding effect between the primer coating and the steel plate substrate is difficult to guarantee, and there is a risk of peeling off, while the primer coating When the layer falls off, it will fall off together with the luminous layer and the top coat, thus forming a whitening phenomenon on the steel plate substrate

[0007] In addition, through the applicant's extensive search, no matter whether it is in domestic or foreign patent documents or in non-patent documents, there is no such thing as a luminous color coated steel plate. The technical inspiration of the preparation method
