Description

  By utilizing a large-diameter granular phosphorescent agent, it is possible to ensure higher brightness and extend the afterglow time than before, and to simplify the painting process with a single liquid mixture of phosphorescent agent and binder. The present invention relates to a pressure-sensitive adhesive one-part phosphorescent paint.

  2. Description of the Related Art Conventionally, phosphorescent agents capable of storing light and spontaneously emitting light have been used in various fields because of high added value and excellent convenience. As an example of the utilization method, there are a method of mixing in a resin to form a modeled object, or a method of mixing in a paint and applying to a wall surface or ceiling surface.

Also, even during the drying process of phosphorescent paints, the phosphorescent material particles can be kept uniformly diffused in the paint layer without settling, and compared with conventional phosphorescent paints without undercoating with white paint. There is a phosphorescent paint having a high luminous efficiency and a long emission time, and a method for using the same (for example, see Patent Document 1).
The above-mentioned Patent Document 1 discloses a phosphorescent paint in which a dispersant, an anti-settling agent, and a phosphorescent material are mixed in a paint stock solution obtained by mixing a colorless transparent clear paint with a curing agent and thinner.
JP 2000-109730 A (page 1-2, FIG. 1)

  However, when a phosphorescent agent is mixed in a resin to form a modeled object or mixed with a coating stock solution and used as a phosphorescent paint, it is necessary to make the particle diameter of the phosphorescent material into a powder of about 7 μm to 30 μm. There was a problem that it led to many troubles and high costs. Also, when a large-diameter granular phosphorescent agent with a particle size of 100 μm or more is mixed with the paint stock solution, the specific gravity of the large-diameter granular phosphorescent agent and the paint is significantly different. Fell and did not paint.

  Therefore, in view of the above points, the present invention can ensure a higher luminance and extend the afterglow time than before by using a large-diameter granular phosphorescent agent, and further, can be applied with a mixed liquid of the phosphorescent agent and a binder. An object of the present invention is to provide a strength-adhesive one-part phosphorescent paint that can simplify the process.

  In order to solve the above problem, the strength-adhesive one-component phosphorescent paint of the present invention is formed by mixing a phosphorescent agent and a binder obtained by adding a thickener and a film-forming aid to an acrylic synthetic resin emulsion. It is characterized by that.

  Mixing a phosphorescent agent and a binder with a thickening agent and a film-forming aid added to an acrylic synthetic resin emulsion, it is possible to use a large-diameter granular phosphorescent agent with a high adhesive strength of 100 μm or more. become. Moreover, even when it is used as a coating material on the wall surface or ceiling surface, the problem that the phosphorescent agent peels off after drying can be solved. Moreover, it is not necessary to make the diameter of the phosphorescent material particles into a powder of about 7 μm to 30 μm, and it is possible to improve work efficiency and reduce costs. Furthermore, by using a large-diameter granular phosphorescent agent, it is possible to ensure high luminance and extend the afterglow time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a strength-adhesive one-component phosphorescent paint according to the present invention will be described with reference to the drawings.
The strength-adhesive one-component phosphorescent paint 1 shown in FIG. 1 is formed by mixing a phosphorescent agent 2 and a binder 3 with a thickener and a film-forming aid added to an acrylic synthetic resin emulsion. Moreover, since the said strong adhesion one-pack type phosphorescent paint 1 has the outstanding adhesive force, it can be used widely as a coating material of a wall surface or a ceiling surface. Furthermore, the strength-adhesive one-component phosphorescent paint 1 according to the present invention comprises a mixed one-component solution of the phosphorescent agent 2 and the binder 3, so that the painting process can be simplified.

  The phosphorescent agent 2 shown in FIG. 2 (a) accumulates light such as sunlight or lighting equipment and spontaneously emits a fantastic fluorescent color in the dark or at night. For example, a strontium aluminate-based phosphorescent agent Is mentioned. In addition, a material produced by mixing a plurality of known metal compounds or rare earths and mixing a general-purpose color developing agent may be used, and the material and the mixing ratio thereof are not particularly limited.

  Moreover, the diameter a of the phosphorescent agent 2 is 100 μm or more, and in particular, a large-diameter granular phosphorescent agent having a diameter of 150 μm to 5000 μm can be used. Thereby, it is not necessary to powder the phosphorescent material particles to about 7 μm to 30 μm by using a pulverizer, and it is possible to improve work efficiency and reduce costs.

  The binder 3 shown in FIG. 2 (b) is formed by adding a thickener and a film-forming aid to an acrylic synthetic resin emulsion, and exhibits high adhesive strength when the phosphorescent agent 2 is mixed. Thereby, for example, when applied to a wall surface or a ceiling surface, the problem that the phosphorescent agent is peeled off even after drying can be solved.

  Moreover, the mixing ratio of the acrylic synthetic resin emulsion, the thickener and the film-forming aid constituting the binder 3 is not particularly limited, and can be appropriately adjusted according to the use, the place where it is used, and the temperature and humidity. preferable. Furthermore, the mixing ratio of the phosphorescent agent 2 and the binder 3 is not particularly limited, and it is desirable to adjust according to the light emission luminance and cost.

  The strength-adhesive one-component phosphorescent paint 1 having the above structure can be applied to the wall surface or ceiling surface using a brush or the like. Is also possible.

The strength adhesion one-pack type phosphorescent paint contained in a container is shown. (A) shows the luminous agent accommodated in the container, and (b) shows the binder.
