Description

Luminescent typed visibility indicator and manufacturing method thereof}

The present invention relates to a luminous type visibility sign and a method of manufacturing the same. More specifically, the present invention relates to a luminous type sign that can luminous for a predetermined time mixed with a synthetic resin base as a baseboard, and then printed with information or decorative designs. It relates to a luminescent visibility sign that can be manufactured as a guidance/decorative sign and can be illuminated and identified for more than 1 hour even at night and in dark places to prevent safety accidents and have improved durability and decorative functions and a method of manufacturing the same.

In general, visibility signs include guide signs or decorative signs such as key chains that have a retroreflective function. Light is retroreflected upon receiving a light source, but due to the problem that the luminous function is not provided in places without a light source, phosphorescent signs are used. Functional and visible signs are mainly used.

Conventional photoluminescent visibility signs accumulate light sources and emit light even in dark places without a light source, but most of them have a very short emission time of up to 10 to 20 minutes, so they cannot function in the event of an emergency evacuation situation such as a fire. Even when it is not fully utilized and is used for decorative purposes, there is a problem in that visibility is reduced and the decorative function cannot be fully exercised.

In addition, the conventional luminous type visibility sign is manufactured by attaching a luminous mixture with a luminous function to a baseboard made of synthetic resin in the form of a sticker to form a luminous layer, and then printing the corresponding information text or decorative design on the luminous layer. Therefore, there is a problem in that the manufacturing process is complicated and the luminous layer is easily peeled off from the baseboard, preventing the luminous function from being properly exercised.

Meanwhile, the effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

A luminous visibility sign according to a preferred embodiment of the present invention is manufactured by mixing a luminous mixture with a synthetic resin at a predetermined weight percent, and includes a baseboard that provides luminous function and durability, and an information text or decorative design on one side of the baseboard. It includes a visibility printed layer that is printed using this printing method and provides a guiding or decorative function.

The baseboard is a means of providing luminous function and durability, and is manufactured by mixing a luminescent mixture with synthetic resin at a predetermined weight percent and then manufacturing it into a panel having a predetermined area and thickness through a known method.

Here, the baseboard is manufactured into a panel having a predetermined area and thickness by mixing 85 to 96 wt% of synthetic resin and 4 to 15 wt% of a photoluminescent mixture. In this case, the photoluminescent mixture contains 20 to 50 wt% of aluminum oxide. , 0.01 to 20% by weight of calcium carbonate, 30 to 60% by weight of strontium carbonate, 1 to 6% by weight of boric acid, 0.01 to 1% by weight of didium trioxide, and 0.02 to 1% by weight of diuphrium trioxide.

Synthetic resins enable the manufacture of baseboards by providing functions such as thermoplasticity, processability, chemical stability, and durability. Since they may be known synthetic resins such as PMMA or MMA, detailed descriptions will be omitted.

Here, 85 to 96% by weight of synthetic resin is added when mixed with the photoluminescent mixture. If it exceeds 96% by weight, transparency is reduced and the light source is absorbed by the photoluminescent mixture or, conversely, the light source is suppressed from emitting light, thereby improving photoluminescence and Visibility is reduced, and if it is less than 85% by weight, durability is reduced and it may be difficult to maintain the shape when manufactured as a baseboard, so it is preferable to have the weight% as above.

Aluminum oxide, CAS number 1344-28-1, provides high heat resistance and optical properties, and is added in an amount of 20 to 50% by weight. If it exceeds 50% by weight, it is an expensive material and requires a lot of manufacturing costs. Due to color limitations, it is difficult to produce signs in various colors, and if the amount is less than 20% by weight, heat resistance cannot be secured, so in the event of a fire, the baseboard is deformed or damaged due to the influence of the surrounding temperature, and optical properties deteriorate. Since the luminescent function of calcium carbonate and strontium carbonate, which are luminescent materials, is not sufficiently exerted, it is preferable to have the same weight percentage as above.

Calcium carbonate, CAS number 471-34-1, provides high photoluminescent properties and various color processing properties, is added in an amount of 0.01 to 20% by weight, and if it exceeds 20% by weight, the manufacturing cost of the baseboard is reduced due to its low price. Although this is reduced, the durability of the baseboard is reduced due to weak mechanical properties, and due to a weak reaction to acid, the baseboard is discolored or corroded by toxic gases in the event of a fire, and if the amount is less than 0.01% by weight, the luminous properties are not sufficiently secured. Since the resistance to high temperature is lowered and the baseboard is deformed or damaged by high temperature in the event of a fire, it is desirable to have the same weight percentage as above.

Strontium carbonate, CAS number 1633-05-2, provides high photoluminescent properties and chemical stability, and is added in an amount of 30 to 60% by weight. If it exceeds 60% by weight, the mixing ability with the synthetic resin is reduced and the photoluminescent component is added. It is difficult to emit light uniformly because it is not distributed properly, and it becomes sensitive to heat, which causes the baseboard to be deformed or damaged in the event of a fire. If it is less than 30% by weight, the intensity of brightness and luminous function are not sufficiently secured for a long time, which reduces visibility and visibility. Therefore, it is preferable to have the same weight percentage as above.

Boric acid, CAS number 100043-35-3, provides high photoluminescent properties and the ability to select various colors, and is added in an amount of 1 to 6% by weight. If it exceeds 6% by weight, the photoluminescent component is rather volatile due to its high volatility. It volatilizes during the manufacturing process, deteriorating the luminous function, and if it is less than 1% by weight, the luminous function deteriorates and the color selection function of the baseboard does not work, so a separate pigment must be added. Therefore, having the above weight % is recommended. good night.

Didium trioxide, CAS number 1308-87-8, provides a retroreflective function and is added at 0.01 to 1% by weight. If it exceeds 1% by weight, the retroreflective function is improved, but the color tone control function is rather poor. It becomes distorted, making it difficult to manufacture the baseboard in the desired color, and if it is less than 0.01% by weight, retroreflectivity is not sufficiently demonstrated, so it is better to have the same weight% as above.

Dieuphrium trioxide, CAS number 1308-96-9, provides a strong photoluminescent effect and long-term luminous persistence, is added at 0.02 to 1% by weight, and if it exceeds 1% by weight, it is a rare earth element and is used during mining and extraction processes. There is a problem of increased manufacturing costs due to environmental problems and high costs, and if the amount is less than 0.02% by weight, the luminous function and luminous persistence are deteriorated, making it difficult to emit light for more than 1 hour, so it cannot function as a luminous type visibility sign that meets fire law standards. Since it cannot be had, it is better to have the same weight percentage as above.

Therefore, according to the baseboard, the photoluminescent mixture is mixed with a synthetic resin at a predetermined weight % and then manufactured into a panel through a known method, thereby providing improved photoluminescent function, luminous sustainability, and durability.

In addition, since the phosphorescent layer is not formed by attaching the phosphorescent mixture to the baseboard in the form of a sticker as in the prior art, manufacturing is much easier and damage to the phosphorescent layer can be minimized.

The visibility print layer provides a guidance or decorative function by printing an information text or decorative design on one side of the baseboard. Since the text or decorative design can be printed using a known printing method, a detailed description is provided. Decided to omit it.

Therefore, according to the visibility printed layer, it is formed by printing on one side of the baseboard that provides luminescence and durability, so it can have strong durability against scratches, etc., and through this, the guidance display function through visibility and visibility can be improved. .

Here, a binder layer may be formed on one side of the baseboard before the visibility print layer is printed. For example, the binder layer is a primer made of polyurethane and is applied to a thickness of 0.04 mm to 0.1 mm, but less than the above thickness. In this case, the printability of the visibility printed layer deteriorates, and if it exceeds the above thickness, the gelation layer becomes thick, the covering bond between the visibility printed layer and the baseboard decreases, and the flexibility of the baseboard decreases, making it susceptible to impact. Because it is damaged, it is desirable to have a limited thickness as described above.

Therefore, according to the photoluminescent visibility sign according to the present invention, the photoluminescent mixture is added to the synthetic resin and is manufactured as a baseboard, so the manufacturing process can be greatly simplified by eliminating the need to configure the sticker-type photoluminescent layer using an adhesive method as in the past. there is.

In addition, by mixing diuphrium trioxide into the photoluminescent mixture, the luminescence persistence of the photoluminescent mixture can be prolonged.

Meanwhile, a method of manufacturing a luminous type visibility sign according to a preferred embodiment of the present invention will be described as follows.

First, a baseboard is manufactured after the photoluminescent mixture is mixed with the synthetic resin at a predetermined weight percent.

Here, the baseboard is manufactured into a panel having a predetermined area and thickness by mixing 85 to 96 wt% of synthetic resin and 4 to 15 wt% of a photoluminescent mixture. In this case, the photoluminescent mixture contains 20 to 50 wt% of aluminum oxide. , 0.01 to 20% by weight of calcium carbonate, 30 to 60% by weight of strontium carbonate, 1 to 6% by weight of boric acid, 0.01 to 1% by weight of didium trioxide, and 0.02 to 1% by weight of diuphrium trioxide.

Afterwards, a visibility print layer that provides guidance or a decorative function is printed on one side of the baseboard through a guide text or decorative design.

Therefore, according to the manufacturing method of the luminous type visibility sign according to the present invention, the luminous type mixture is added to the synthetic resin and the baseboard is manufactured as a whole, so that the sticker-type phosphorescent layer does not need to be formed by an adhesive method as in the past, making the manufacturing process very simple.
