  FIG. 2 is a conceptual diagram of a vacuum stirring and dispersing apparatus used for producing a nano-order dispersed water-based multicolor paint according to the present invention. The vacuum stirring and dispersing apparatus used in the production of the nano-order dispersion type water-based multicolor paint according to the present invention has a flange so that the container part and the lid part can be opened and closed, and the paint composition raw material is used in the container part. After the charging, the container part and the lid part are tightened by closely contacting the flange so that the inside of the container can be decompressed.

  After the raw material of the coating composition is put into the container part and the flange is tightened, the vacuum pump is operated to depressurize the container body, and the propeller is rotated to disperse the mixture. In the method for producing a nano-order dispersed water-based multicolor phosphorescent paint according to the present invention, it is desirable to adjust the pressure in the container during the stirring and dispersing step to 1 Pa to 50000 Pa.

  A particularly preferred nanonization step is to alternately repeat the pressure reduction step and the stirring dispersion step. Of course, it is also effective to reduce the pressure after adjusting the pressure during the stirring and dispersing step. In this case, it is more effective to repeat the steps in the order of reduced pressure stirring dispersion at low speed rotation and reduced pressure stirring dispersion at high speed rotation. In the case of alternately performing the reduced pressure stirring dispersion at the low speed and the high speed rotation as described above, the steps of the reduced pressure stirring dispersion at the low speed rotation within 1 minute to 30 minutes and the reduced pressure stirring dispersion at the high speed rotation within 5 minutes to 3 hours.

  In this example, a nano-order dispersed water-based multicolor phosphorescent paint was produced. Here, an example of a method for producing a nano-order dispersed water-based multicolor phosphorescent paint according to the present invention will be described, and at the same time, a vacuum stirring and dispersing apparatus used for producing a nano-order dispersed water-based multicolor paint will be described.

  In this example, an acrylic ester copolymer aqueous emulsion was dispersed in water as a raw material emulsion for a nano-order dispersion type water-based multicolor phosphorescent paint. In addition, as raw material emulsion used for this invention, it is not limited to the material which concerns on a present Example, Various synthetic resin emulsions and / or water-soluble resin can be used suitably.

  In this example, 110 parts by weight of water was added to 100 parts by weight of the acrylic ester copolymer aqueous emulsion, and 2.5 parts by weight of an antifoaming agent and 0.4 parts by weight of a wetting agent and an antifoaming agent. Then, 2.5 parts by weight of the dry preparation agent was added and stirred.

  To this aqueous emulsion, a phosphorescent pigment and a light diffusing agent are further added and stirred to obtain an aqueous phosphorescent paint raw material, which is further nanosized by a vacuum stirring and dispersing process to produce a nano-order dispersed aqueous multicolor phosphorescent paint. Obtained. In the present example, 25 parts by weight of a phosphorescent pigment containing strontium aluminum oxide as a main component and 5 parts by weight of a light diffusing agent are added to 100 parts by weight of the aqueous emulsion, and stirred to obtain a nano-order dispersion type. Although a water-based multicolor phosphorescent paint was obtained, the present invention is not limited to these materials and their blend ratios.

  As the phosphorescent pigment used in the present invention, any material containing at least one of strontium, calcium, and barium, aluminum, and oxygen can be used. Also, the blending ratio can be arbitrarily set with respect to the aqueous emulsion. Furthermore, the light diffusing agent and the compounding ratio thereof can be arbitrarily set, and the light diffusing agent may not be added.

  After sufficiently mixing the above-mentioned mixed composition with stirring, the aqueous emulsion coating composition is put into a vacuum stirring and dispersing apparatus used for producing a nano-order dispersion-type aqueous multicolor coating, and the vacuum stirring and dispersing is performed. A nano-order dispersion-type water-based multicolor phosphorescent paint was obtained.

  FIG. 2 shows a conceptual diagram of a vacuum stirring and dispersing apparatus used for producing a nano-order dispersion type water-based multicolor phosphorescent paint according to the present invention. The vacuum stirring and dispersing apparatus used for producing the nano-order dispersion type water-based multicolor phosphorescent coating material according to the present invention has a flange so that the container part and the lid part can be opened and closed, and the coating composition raw material is used as the container part. After charging, the container part and the lid part are tightened by tightly attaching the flange so that the inside of the container can be decompressed.

  After the coating composition raw material was put into the container part and the flange was tightened, the inside of the container was depressurized by operating a vacuum pump, and the propeller was rotated to perform stirring and dispersion. In the method for producing a nano-order dispersed water-based multicolor phosphorescent paint according to the present invention, it is desirable to adjust the pressure in the container during the stirring and dispersing step to 1 Pa to 50000 Pa. The pressure in the container body is more preferably adjusted to 1 Pa to 5000 Pa, and more preferably adjusted to 1 Pa to 500 Pa. In this example, the pressure in the container fluctuated depending on the amount of air remaining in the emulsion during the process, but the degree of foaming of the emulsion in the container was observed as appropriate, and the degree of pressure reduction was adjusted with a valve.

  It is effective for stirring and dispersing that the propeller installed in the container has a shape in which emulsion particles are cut and dispersed. Moreover, it is desirable to maintain the rotation speed of the propeller during the stirring and dispersing step in a range of 200 rpm to 5000 rpm. The decompression and / or stirring / dispersing step is desirably performed in a total range of 5 minutes to 24 hours. The decompression and / or stirring dispersion step is more preferably performed in a range of 30 minutes to 12 hours in total, more preferably in a range of 1 hour to 6 hours, and more preferably in a range of 2 hours to 4 hours. More desirable to do.

  The step of stirring and dispersing by rotating the propeller installed in the container and the step of reducing pressure are alternately repeated or simultaneously performed. A particularly preferred nanonization step is to alternately repeat the pressure reduction step and the stirring dispersion step. In this example, first, after sealing the flange, pressure reduction was performed for 10 minutes while rotating the propeller at a low speed of 1000 rpm or less, and then the rotation speed of the propeller was increased to 1500 rpm or more for 30 minutes under reduced pressure stirring dispersion. Thereafter, the pressure was reduced again for 10 minutes at a low speed rotation, and further, stirring and dispersing under reduced pressure for 1 hour was performed at a high speed rotation. Finally, the mixture was stirred and dispersed under reduced pressure for 10 minutes at a low speed to obtain a nano-order dispersed water-based multicolor phosphorescent paint.

  By changing the phosphorescent paint used in Example 1 to a fluorescent paint, a nano-order dispersed water-based multicolor fluorescent paint was obtained in the same process using the same apparatus. Furthermore, a nano-order dispersed water-based multicolor retroreflective coating material, a nano-order dispersed water-based multicolor phosphorescent retroreflective coating material, and a nano-order dispersed water-based multicolor fluorescent retroreflective coating material are obtained by adding and dispersing a retroreflective agent. I was able to do it.

  Here, the nano-order-dispersed water-based multicolor paint according to the present invention is water-based, but by stirring and dispersing under the above conditions, the emulsion diameter is set to 10 μm or less, so that the sedimentation speed is small and the pot life is long. It was a phosphorescent paint. Furthermore, the emulsion diameter is preferably 5 μm or less, more preferably 1 μm or less, and further preferably 0.5 μm or less.

  In general phosphorescent paints and the like, especially water-based phosphorescent paints and the like, the emulsion containing the pigment has a large diameter, so that it tends to settle, and precipitation occurs during storage for several days to several weeks, resulting in deterioration of film formability. However, the nano-order dispersion type water-based multicolor paint according to the present invention is dispersed to the nano-order in which the diameter of the emulsion containing the pigment is very small despite being water-based, so that the sedimentation rate is slow and it is 1 year or more. Even after a storage period, it was a paint having a sufficiently good film forming property.

  Moreover, since the nano-order dispersion type water-based multicolor paint according to the present invention is water-based, it has a low environmental load and can be used for various applications as a very ecological phosphorescent paint.

  Furthermore, since the nano-order dispersion type water-based multicolor paint according to the present invention performs nano-order dispersion, the coloration at the time of phosphorescence / fluorescence emission is the same as or similar to the coloration in daylight. Produce. In general multicolor phosphorescent paint, it shows multiple colors in daylight, but when it emits fluorescent light, it becomes the emission color of the phosphorescent paint (generally yellowish green, etc.). Although there was a problem with the appearance, this point is improved in the present invention, and the visibility and display are greatly improved. Also, by adding a retroreflective material to these, a paint that can provide a highly visible coating film was realized.

  In addition, the nano-order dispersion type water-based multicolor paint according to the present invention has nano-order dispersion, so that the film formability is good, and a good coating film can be formed by various film forming methods such as coating and spraying. Can be obtained. Moreover, the characteristics such as the adhesion strength of the coating film, the strength of the coating film itself, the weather resistance, and the light resistance were also good. Furthermore, it is easy to obtain a thick film by overcoating, and it has characteristics that can be used for various applications.

  In the production method of the nano-order dispersion type water-based multicolor paint and the nano-order dispersion type water-based multicolor paint, the present invention suppresses the precipitation of the pigment even if it is completely aqueous by stirring and dispersing while degassing under reduced pressure. Nano order dispersed water-based multi-color coating material that has a long pot life, excellent film formation characteristics, and realizes multicolor that is equivalent to or close to the coloration in daylight in color storage during phosphorescence / fluorescence. A method for producing a dispersion-type water-based multicolor paint and a vacuum stirring and dispersing apparatus used for producing a nano-order-dispersion-type water-based multicolor paint are realized, which is water-based, has a long pot life, and has practical film forming conditions. A multi-color paint that can produce a film that is practical in terms of film finish, durability, and light resistance, and that achieves multiple colors that are equivalent to or similar to those in daylight, even in color storage during phosphorescence / fluorescence.
