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

Example Embodiment

[0028] Example 1:

[0029] A) Material selection and cleaning. Select the galvanized steel sheet with a thickness of 0.6mm within one month from the production date. The thickness of the zinc layer of the galvanized steel sheet is 30μm. The galvanized steel sheet should be brushed and cleaned first, and then alkali Washing and electrolytic cleaning in order to remove the oxide scale and / or oil stains on the surface of the galvanized steel sheet. After cleaning, drying is carried out at a drying temperature of 90°C and a steel sheet traveling speed of 60m / min to obtain a steel sheet substrate 1;

[0030] B) Activation treatment, chemical coating is performed on the surface of one side of the steel plate substrate 1 obtained in step A) to form a chemical coating 11 on this side surface, and the thickness of the chemical coating 11 formed by the chemical coating is 7μm, the chemical coating mentioned here is to coat hexavalent chromate on the surface of the steel plate substrate 1,...

[0036] Example 3:

[0037] Only change the thickness of the sheet material in step A) to 0.2mm galvanized steel, and the thickness of the galvanized zinc layer to 10μm. The cleaning method is: first brush cleaning, then electrolytic cleaning, after cleaning The drying temperature is changed to 80°C, the steel travel speed is 55m / min; the thickness of the chemical coating 11 in step B) is changed to 8.5μm, the drying temperature after coating the hexavalent chromium solution is changed to 110°C, and the drying time Change to 9s; change the thickness of primer coating 2 in step C) to 25μm, and change the drying and curing temperature and time after primer coating to 215℃ and 42s, respectively. Change the thickness of topcoat coating 3 After the topcoat is applied, the temperature and time of drying and curing are respectively changed to 230°C and 50s; the thickness of the luminous layer 4 in step D) is changed to 90μm, and the temperature and time of drying and curing are changed...

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 ...
