Abstract

The present invention relates to a sign channel manufactured with an epoxy board and a solid sign board using the same. The brightness of side luminescence can be uniform by forming a side with a constant thickness along the appearance of a sing board. A yellowing phenomenon due to an ultraviolet ray even if the sign board is exposed to the air is prevented by using an epoxy board made of a special component. A side and a light transparence cover are integrated at one time by using an automatic cutter such as a CNC machine. The installation and the assembly of a solid sign board are quickly performed by attaching a substrate having LEDs to one open side of the sign board.

Description

SIGN CHANNEL MANUFACTURED WITH EPOXY BOARD AND SOLID SIGN BOARD USING THE SAME}

The present invention relates to a three-dimensional sign, and more particularly, to a sign channel made of an epoxy plate and a three-dimensional sign using the same.

The three-dimensional signage is to protrude a sign cover consisting of letters, figures, etc., generally, as shown in Figure 7, the signage channel 300 to form a space to accommodate the light emitting body 200, such as LED, and the It consists of a light transmitting cover 100 fixed to the locking step 310 formed in the signage channel 300 with a predetermined screw 400 (aka 'piece').

The signage channel 300 is generally formed integrally with a metal or divided into a bottom portion to which the light emitter 200 is attached and a side portion to surround the bottom portion and connected to the light transmitting cover 100, and are manufactured and used in separate processes. .

In the former case, only front emission is possible, and when a character or figure constituting a sign cover is complicated, there is a problem that it is difficult to accurately implement the shape.

In the latter case, the back light and the side light can be emitted depending on the material of the bottom and the side, but the joining of the bottom and the side is not easy. There is the same problem as the former.

In order to solve the above problems, Korean Patent No. 10-0650445 discloses cutting the MDF (Medium Density Fiberboard) material with a CNC engraver or the like to form a signage channel integrally with the bottom and side parts or to form only the side parts. have.

The MDF presented in the Korean Patent No. 10-0650445 is a fibrous plate manufactured to have a medium density of about 0.5 g / cm 3 by pressurizing fine wood chips such as sawdust with an adhesive, so it is excellent in workability and very weak in moisture and inferior in rigidity. There is this.

In addition, the Korean Patent No. 10-0650445 adopts a method of impregnating the processed MDF in a liquid epoxy, acrylic, UP (unsaturated polyester) or resin for a certain time to overcome the disadvantages of the MDF and then pulled out to cure However, the process is complicated, side light emission has a problem that is difficult to implement.

Meanwhile, in Korean Patent No. 10-1061976, a translucent medium having a predetermined thickness of 8 mm or more is made by using a laser cutting machine, etc., and a sign cover shape is formed, a groove is formed on a surface by a drill, etc., and then a light source is inserted, and then fluidity such as epoxy A technique for filling and sealing the recesses with a compound is disclosed.

The Korean Patent No. 10-1061976 is a method of forming the groove for inserting the light source in the translucent medium such as acrylic resin has the advantage that the front, side and back light can be emitted, but the thickness of the translucent medium formed by the sign channel is too thick, There is a problem that the three-dimensional signboard is too heavy, and the sealing is filled with a fluid compound such as epoxy in the groove into which the light source is inserted, and there is a problem in that the transmittance of light from the light source is lowered depending on the light-transmitting medium and the constituents of the fluid compound. In particular, the corner portion that is farthest from the light source has a problem of being relatively dark.

In addition, when the LED is used as a light source in Korea Patent No. 10-1061976 and the groove is filled with a fluid compound such as epoxy, the LED life can be shortened due to the problem that the heat generated from the LED cannot be easily discharged (heat dissipated). However, there is a problem in that the epoxy used as a light-transmitting medium or filled with grooves is easily discolored due to yellowing, so that light of a desired color cannot be emitted.

Furthermore, in the Korean Patent No. 10-1061976, the recess is formed in a separate process unlike the sign cover exterior process, which is uneconomical in terms of processing time and cost, and it is difficult to replace the light source when the light source fails, thus re-producing the three-dimensional signboard. There is a problem to be done.

In particular, epoxy is known to be used in a three-dimensional signboard, such as adhesives by using the excellent light dispersion effect and hardening from the liquid phase to a solid phase, but yellowing phenomenon occurs in almost a year when in direct sunlight in contact with air, the desired color There has been a problem that can not be.

Therefore, there has been a steady demand for the development of epoxy materials suitable for use in three-dimensional signs.

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

1 is a photograph showing a state of making a signboard channel 3 according to an embodiment of the present invention, the epoxy plate 2 having the same thickness as the height of the later protruded cubic plate on the adsorption plate (1) , According to the program input to the CNC engraver (4) shows the appearance of the signboard sign and the inner space formed in a single process.

Therefore, the signage channel according to an embodiment of the present invention, referring to Figures 1 to 3, the signage channel to form a predetermined space portion 11 to accommodate the light emitting body 26 of the three-dimensional signage (10, 20) In (10), the side surface of the space portion 11 with a predetermined thickness (T _L ) while following the outline of the signboard sign with an epoxy plate (2) having a thickness of the protruding height of the three-dimensional signboard (10, 20) (14) is formed.

The thickness T _L of the side surface 14 preferably has a thickness enough to disperse the light of the light emitter 26 to be accommodated inside, depending on the type of the light emitter 26 and the material of the epoxy plate 2. It may vary, but may be 4-5 mm.

The space 11 may be formed while penetrating the thickness of the epoxy plate 2 so as to surround only the side surface 14 of a predetermined thickness, as shown in Figures 1 to 3, the front surface of the sign On the front of the space portion 11 corresponding to the conventional transparent transmission cover 12 is preferably formed so that the epoxy plate 2 is formed integrally with the side surface 14 of the space portion 11. Do.

In addition, the thickness T _F of the light transmitting cover 12 is preferably formed to be twice or more thicker than the thickness T _L of the side surface 14 of the space 11. By doing so, the light diffusion in the light transmissive cover 12 is made larger than the side surface 14, thereby reducing the difference in illuminance at the corners of the light transmissive cover 12, and darkening at the edges of the conventional light transmissive cover 12. Losing problems can be solved.

In addition, as shown in FIG. 4, a color sheet 16 is further attached to the upper portion of the light transmitting cover 12, or as illustrated in FIG. 5, the color sheet 16 protrudes forward in the convex lens shape 18. Can be further formed. By doing so, it is possible to maximize various color and spectral effects.

In another embodiment, as shown in FIG. 6, the sidewalls 14 of the signage channel 10 may be formed with a coating film 19 using oily ink. By doing so, the illuminance of the side light emission can be made uniform with the uniform thickness of the side surface 14, and the side light emission having various colors can be realized.

The oil-based ink for ink, 9 to 11 parts by weight of oil-based transparent ink, anon with respect to 2 parts by weight of color ink so as to maintain a certain level of illuminance by side light emission and remain without peeling after application to the side surface 14 formed of epoxy. (Cyclohexanone) It is preferable to use what mix | blends 11-13 weight part and 0.01-0.03 weight part of acetone.

On the other hand, the epoxy plate 2 used as the material of the signage channel 10 in each of the above embodiments is a formamidine group compound, the 2,2'-dimethyl-4,4'-methylene as a curing agent It is preferable that bis (cyclohexaneamine) (2,2'-Dimethyl-4,4'-methylenebis (cyclohexanamine): CAS No. 6864-37-5) is prepared.

This is because formamidine has more than 30% of UV protection and absorption effect in the ultraviolet wavelength range of 290 ~ 330 nm than benzotriazole group or benzophenone group, and it has high solubility with other main ingredients of epoxy. Because.

The preferred curing agent is 2,2'-dimethyl-4,4'-methylenebis (cyclohexaneamine), which is aromatic amine and resistant to external harsh environments such as ultraviolet rays, water, and wind. This is because it is suitable for the following.

In a more specific embodiment, the subject is 20 to 50% by weight of bisphenol A diglycidyl ether (CAS No. 25068-38-6), polypropylene glycol diglycidyl ether (Polypropylene glycol diglycidyl ether: CAS No. 26142-30-3) 5-10 wt%, glycidyl phenyl ether (CAS No. 122-60-1) 0.05-2 wt%, 3-glycidyl propyl 2 to 5% by weight of trimethoxy silane (3-Glycidyl propyl trimethoxy silane: CAS No. CAS 33580-59-5), N2- (4-methoxycarbonylphenyl) -N'-methyl as the formamidine compound -N2-phenylformamidine (N2- (4-Methoxycabonylphenyl) -N'-methyl-N2-phenylformamidine: CAS No. 33089-74-6) 0.05 to 2% by weight, silicon dioxide (CAS No. 7631 -86-9) 30 to 40% by weight and calcium carbonate (CaCO3: CAS No. 471-34-1) 5 to 20% by weight.

Here, the form bisphenol A diglycidyl ether is a main epoxy resin, when blended in less than 20% by weight causes a hardness problem, if it exceeds 50% by weight it is difficult to add cost and functionality.

Since the polypropylene glycol diglycidyl ether is for controlling the viscosity with a hydrophobic resin, when the viscosity is less than 5% by weight, it is difficult to mix the main ingredients, and when the content exceeds 10% by weight, the hardness becomes weak. There is this.

The glycidyl phenyl ether is formulated to promote flexibility, cold resistance, and aging resistance as a plasticizer and stabilizer and to induce epoxidation. When glycidyl phenyl ether is less than 0.05 wt%, the plasticizing effect is insignificant. It causes problems.

The 3-glycidyl propyl trimethoxy silane is used to crosslink an organic-inorganic linkage with a crosslinking agent and an initiator. When less than 2% by weight, crosslinking between resins becomes poor, but when the amount exceeds 5% by weight, the crosslinking agent is used. There is a problem that the crosslinking strength is weakened by causing self hydrolysis.

The N2- (4-methoxycarbonylphenyl) -N'-methyl-N2-phenylformamidine is a sunscreen, a sunscreen and a sun absorber when the weight is less than 0.05% by weight, thus preventing the effect of ultraviolet rays. If it exceeds 2% by weight, it is rather difficult to achieve the object of the present invention due to heat generation and heat resistance reduction.

The silicon dioxide is used as a filler, a reinforcing agent, and a light diffusing agent, and a particle size of 5 to 25 μm is preferable, and when the compounding amount is less than 30 wt%, the filler effect is reduced, but when it exceeds 40 wt%, it is too strong. The light diffusion effect causes problems such as glare.

The calcium carbonate is used as an opaque agent and a filler, when less than 5% by weight, the opacity and heat resistance effect is insignificant, but when it exceeds 20% by weight, there is a problem that causes soft nitriding.

And, the curing agent 30 to 50% by weight of the 2,2'-dimethyl-4,4'-methylenebis (cyclohexaneamine) (CAS No. 6864-37-5), isophorone diamine (CAS No. 6864- 37-5) 30-40 wt%, Norbornane diamine (CAS No. 6864-37-5) 10-20 wt%, Salicylic acid (CAS No. 69-72-7) 0.5-2 wt%, Antifoam 0.1-1 Wt%, leveling agent 1 to 5% by weight.

Herein, the 2,2'-dimethyl-4,4'-methylenebis (cyclohexaneamine), the isophorone diamine, and the norbornane diamine all play a role of forming an organic building block with a nitrogen compound. As described above, the curing agent is preferably substantially composed of only 2,2'-dimethyl-4,4'-methylenebis (cyclohexaneamine), but is partially substituted with isophorone diamine and norbornane diamine in the above-described content. can do.

The salicylic acid is used as an ultraviolet stabilizer, anti-yellowing agent, a curing accelerator, when less than 0.5% by weight there is a problem that the reaction time increases, but when it exceeds 2% by weight there is a problem that the uniformity is poor.

When the antifoam is less than 0.1% by weight as a bubble suppression, stabilizer, the effect is insignificant, but when it exceeds 1% by weight there is a problem that the density is poor.

The leveling agent is added to improve the uniform coating film formation, smooth surface, mixed resin composition surface flow uniformity, etc., if less than 1% by weight has a problem that the surface and the inside is formed, but 3% by weight When it exceeds, it will fall back and a viscosity will become weak too much.

The mixing ratio of the main material and the curing agent is preferably 10 to 20 parts by weight of the curing agent with respect to 100 parts by weight of the main body, which is due to poor crosslinking when the curing agent is blended to less than 10 parts by weight of the standard. There is a problem of inferior density of the epoxy plate, and when blending more than 20 parts by weight, there is a problem in that the epoxy plate is non-uniform due to some excessive crosslinking.

On the other hand, the three-dimensional signboard according to another embodiment of the present invention can be variously implemented for any one or more of the front light emitting, side light emitting and the rear light emitting using the signage channel 10 according to each embodiment.

2 and 3 illustrate an example in which the light emitting member 20 is fastened to an open bottom surface of the signage channel 10 as a three-dimensional signboard for front emission and side emission. Here, the light emitting member 20 may be composed of a substrate 22 mounted with a plurality of LEDs 26 as a light emitter.

In addition, the substrate 22 is formed of a heat sink such as an aluminum plate, and the plurality of LEDs 26 to be located in the space portion 11 of the signage channel 10 on the substrate 22 includes a printed circuit board ( PCB, it is preferable to mount via 24, by doing so it is also possible to increase the heat dissipation effect of the LED 26, which is a light emitter, and to facilitate the replacement in the event of LED 26 failure.

2 is a through hole for the LED 26 power supply line, it may be formed on one side of the substrate 22, it may be formed on one side 14 of the signage channel (10).

The sign channel 10 and the light emitting member 20 are fastened by using an adhesive such as instant adhesive or silicon, and as shown in FIG. 13 can be made simple by pushing the said board | substrate 22 into it.

In addition, even when installing the three-dimensional signboard according to the embodiment shown in Figure 2, it can be quickly installed in the desired place by using the adhesive means such as double-sided tape or silicon on the back of the substrate (22).
