Technical Field

The invention relates to a method for manufacturing a fluorescent signboard.

Background

Fluorescent powder, commonly known as noctilucent powder, is generally classified into photo-induced energy storage noctilucent powder and noctilucent powder with radioactivity. The luminous powder is used for storing light energy after the fluorescent powder is irradiated by natural light, daylight lamp light, ultraviolet light and the like, and slowly releases the light energy in a fluorescent mode after the light irradiation is stopped, so that the luminous powder can still see luminescence at night or in a dark place for several hours to more than ten hours, and the luminous powder can self-emit light in a dark environment, so that the luminous powder is very suitable for manufacturing safety signboards for fire fighting and the like. The current method for manufacturing the fluorescent signboard comprises the following steps: mixing a binder (such as organic binders like silica gel or epoxy resin) and fluorescent powder to prepare fluorescent slurry, then coating the fluorescent slurry on the surface of the signboard in a screen printing mode, and finally drying to form the fluorescent label. The silk screen printing needs to manufacture a silk screen printing plate, and the fluorescent slurry is transferred to a printing stock through meshes of the image-text part by extrusion of a scraper plate during printing, so that the process is very complex.

Technical personnel try to manufacture the fluorescent signboard by adopting an ink jet printing method, but because the fluorescent powder particles in the fluorescent slurry are large, the ink jet head is easily blocked, the ink jet printing operation is difficult to last, the ink jet head needs to be replaced or cleaned frequently, and the printing quality is difficult to ensure, the fluorescent slurry cannot be manufactured into the fluorescent signboard by adopting the ink jet printing method.

Disclosure of Invention

The invention aims to provide a manufacturing method of a fluorescent signboard with a simple process.

The manufacturing method of the fluorescent signboard comprises the following steps:

A. putting the binder into an ink-jet printer, and forming a marking pattern on the surface of the signboard by adopting an ink-jet printing mode;

B. bonding fluorescent powder on the mark pattern;

C. and curing the adhesive on the signboard so as to fix the fluorescent powder at the marking pattern on the signboard.

In the manufacturing method, the binder is only put into the ink-jet printer instead of the mixed slurry of the binder and the fluorescent powder, so that the problem of ink-jet head blockage is avoided, the identification pattern can be formed on the signboard by adopting an ink-jet printing mode with simple process, and then the fluorescent powder is adhered and solidified on the identification pattern to form the fluorescent identification pattern.

Specifically, in the step B, the following two ways are adopted for bonding the fluorescent powder to the identification pattern:

1. and contacting the signboard with the surface of the flat fluorescent powder stack, so that the fluorescent powder is bonded at the identification pattern.

2. And directly blowing the fluorescent powder to the surface of the signboard, so that the fluorescent powder is bonded at the identification pattern. In this step, a blower may be used to blow the phosphor. The front face of the signboard is upward, the fluorescent powder is blown into the air by the wind power of the fan, and the fluorescent powder uniformly falls on the signboard below under the action of the self gravity.

Of course, the fluorescent powder can be scattered on the surface of the signboard by hand.

In order to ensure that the fluorescent mark pattern is relatively flat, the fluorescent powder on the surface of the signboard can be scraped by a scraper.

In the two modes, all the positions on the signboard are contacted with the fluorescent powder, and part of the fluorescent powder is possibly adsorbed at the positions except the identification pattern on the signboard.

Further, in the step D, redundant fluorescent powder on the signboard is removed in a mode of blowing or sucking air to the signboard. Since the phosphor powder at the logo pattern is already adhered and fixed to the signboard by the adhesive, it is not separated from the signboard in the step D.

Further, the adhesive is UV ink, and in the step C, the UV ink is cured by adopting an ultraviolet irradiation mode. The UV ink is not easy to cure, can leave a long operation time for the operation of the step B, can be cured more quickly after being irradiated by ultraviolet rays, and is more firmly bonded. Of course, other types of inks suitable for ink jet printers can be used as the binder, and since the inks are a mixture of an oily vehicle and a pigment milled together, they have a certain viscosity and can act as a binder.

The method for manufacturing the fluorescent signboard adopts the ink jet printing mode to form the marking pattern, has the advantages of simple process and more flexible design of the marking pattern, and is very suitable for manufacturing the planar fluorescent signboard.
