DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reflective device, and more particularly to a laminated reflective device that improves conventional reflective materials and improves their weather resistance, chemical resistance, and stain resistance. Conventionally, various types of reflective materials such as reflective sheets and reflective cloths have been commonly used. For example, in road signs, traffic safety equipment, advertising signboards, and various badges, the lifespan of the reflective material itself is limited to about 5 years at the most.
Furthermore, when these reflective materials are used for road signs, etc., tar, dust, etc. from the exhaust gas from automobiles adhere to the surface of the reflective materials, making it impossible to fully demonstrate their original reflective function. Due to this contamination, functional deterioration is generally said to occur within one month. Contamination caused by these exhaust gases is physically and chemically attached to the surface of the reflective material, so it is impossible to restore it even with physical or chemical cleaning. In order to overcome these drawbacks, methods of coating the surface of reflective materials with various types of clear paints have been studied or partially implemented in the United States, but the following requirements must be met: I cannot say that I am fully satisfied. (1) The coating film is thin. Even if a clear coat is applied to the surface of the reflective material, if the surface of the reflective material has unevenness, it will not be able to adequately cover the surface of the reflective material. In other words, physical contamination cannot be improved. Also, the film thickness that can be applied in one coating is
It is about 10 to 20μ. (2) Resins that can be used as coatings include urethane, acrylic, and glass cotton lacquer, but these require fluidity and are therefore limited in their physical and chemical performance. (3) Workability is difficult. Coating methods include air spray, dip coating, brush coating, and roller coating, but all of them require a drying process because they are solvent-based, and dirt and dust may adhere to them before the coating dries. There are some problems that cannot be avoided. The object of the present invention is to provide a novel reflector that completely solves these problems. An embodiment of the present invention will be described below with reference to the drawings. The reflecting device A is fixed to a substrate 1 via an adhesive 2, and has characters, figures, etc. drawn on its surface, and is used as a road sign, an advertising signboard, or the like. In the reflecting device A, a focusing resin 4 as a reflective material is laminated on a reflecting plate 3 formed by vapor deposition of aluminum.
A large number of small spherical glass beads 5 are placed on top, and the glass beads 5 are uniformly coated with a surface resin 6, and a protective film 7 is further placed on the surface resin 6.
It is made by laminating layers. The protective film 7 is made of a material that has excellent weather resistance, chemical resistance, and stain resistance, and is made of a mixture of vinyl chloride, ultraviolet absorber, and fluorine resin and molded into a thin transparent sheet. It consists of a film, and this film 7 is pasted or pressed onto the surface resin 6 with an adhesive or the like. In the above reflecting device A, the light incident from the transparent protective film 7 hits the reflecting plate 3 via the surface resin 6 - glass beads 5 - focusing resin 4.
The reflected light passes through the focusing resin 4, the glass beads 5, the surface resin 6, and the protective film 7, and then exits to the outside. According to the present invention, a protective film 7 that satisfies various performances is laminated in advance on the surface of the conventional reflective materials 3, 4, 5, and 6, and the lamination method has the following advantages. Since the film 7 to be laminated can be selected from various resins, it is not limited to the type of solvent. Therefore, any physical or chemical performance can be obtained. The film 7 can have any thickness.
That is, the thickness of the film 7 is selectively used depending on the surface condition of the reflective materials 3, 4, 5, and 6 or the required performance. For example, if the surface of the reflective material is extremely uneven, use a thick film. Easy to work with. The processing work is simple and easy since it is only necessary to laminate the surface of various reflective materials. Conventional coatings using solvents require a drying process and at the same time, the coating has complex refraction regarding the incidence and reflection of light, making useful reflection extremely weak.However, in the case of lamination using the reflective device of the present invention, the film Since the thickness is constant, complex refraction is reduced and more reflected light can be obtained. High performance membranes can be used. Since it is a film laminate, it does not require a solvent, and therefore any film that meets requirements such as stain resistance, weather resistance, chemical resistance, abrasion resistance, etc. can be used. Next, we tested the performance of the reflector according to the present invention, and the effects shown in Table (1) were obtained. Test conditions 1 Weather resistance Sunshine W-O-M 200 hours are converted into one year. 2. Add one drop of xylene (pure) to the film surface, cover with a watch glass, and leave at 20°C for 24 hours to examine the surface condition. 3 Use methyl alcohol in the same manner as in 2. 4 Write on each test piece with black, blue, and red magic (solvent type) (trademark), leave it for 24 hours, wash with alcohol, and judge by the degree of marks left. 5. Place the test piece on the exhaust gas vent of the car for about 5 minutes, leave it for 24 hours, then wipe it with xylene and check the condition of the mark. 6. Immerse in 5% sub-aqueous solution for 24 hours and check the surface condition such as browning and blistering. 7 Immerse in spindle oil at 60℃ for 30 minutes. 8 Soaked in 5% ammonia aqueous solution for 24 hours. 9 Soaked in 5% hydrochloric acid aqueous solution for 24 hours. 10 Soaked in 5% caustic soda aqueous solution for 24 hours. 11 Place the test piece in a desiccator with a diameter of 30 cm, burn the 5 double-cut pieces, leave it for a week, then wipe it with ethyl alcohol and check the degree of yellowing on the surface. Judgment display ◎ Very good 〇 Excellent × Poor ×× Very poor [Table]
