Description

Dual acryl plate

The present invention relates to a double acrylic plate, and more particularly, to an acrylic plate excellent in aesthetic effect by different colors on the front and back.

In general, acrylic plates are widely used for signboards for advertisement and interior props for interior decoration, and these acrylic plates are most commonly used of transparent materials, and they may be molded into a sheet or curved to have a curved surface during the molding process. The shape and shape, such as to be used in various forms as needed.

In the above, the acrylic plate is the most common transparent material, but also adds color to the acrylic plate for aesthetic effect, the method is a method of forming by adding a pigment that is expressed in the color forming process and the molded acrylic plate There is a method of coating the color on the surface of the.

In order to increase the aesthetic effect among these methods, it is frequently necessary to have different colors on the front and back of the acrylic plate, in which case the method of adding the above pigment only represents one color to be used. To do this, a method of coating and using different colors on the front and back of the acrylic plate has been used.

However, there has been a problem in that the coating layer is easily peeled off and thus the color is changed or disappears when the color is coated.

That is, when the coated acrylic plate is exposed to sunlight, rain, wind, etc. for a long time, or touches a lot of human hands, the coating layer is peeled off and the color is discolored, thus deteriorating aesthetics and lowering the advertisement, propaganda or decoration effect that is the purpose of signboards or interior props. There have been problems such as letting.

In addition, there is also a method of bonding two acrylic plates having different colors to each other, but even in this case, there is a problem that the adhesive force does not last long and can not be used anymore.

The present invention has been devised to solve the conventional problems as described above, the object of the present invention in molding the acrylic plate, from the forming step to form a different color on the front and back, aesthetical beauty It is to provide a double acrylic plate that promotes and allows for permanent use.

The present invention for achieving the above object is to form a first liquid resin mixed with a catalyst and a raw material at a constant ratio for 3 hours to 4 hours at 50 ℃, heat treatment at 80 ℃ for 2 hours to 3 hours the first plate After forming a second liquid resin mixed with a catalyst, which is reduced by 1/2 of the catalyst ratio of the first liquid resin to the raw material on the upper side of the first plate, and molded at 50 ℃ 3 to 4 hours, The second plate is formed by heat treatment at 80 ° C. for 2 to 3 hours, wherein the first plate and the second plate are melt-bonded with each other.

13: 2nd liquid resin 14: 2nd edition 16: Molding mold

When described in detail based on the accompanying drawings the configuration and operation of the present invention as follows.

1 is a process diagram schematically illustrating a process of molding a double acrylic plate according to the present invention, a process of pouring a first liquid resin 11 into a mold 16, and a first liquid resin 11 is molded. A process of forming the first plate 12, a process of pouring the second liquid resin 13 on the first plate 12, a process of melting and bonding the first plate 12 and the second plate 14 to each other, The finished double acrylic plate 10 separated from the molding die 16 is shown in schematic order.

As shown in the drawings, the present invention relates to a double acrylic plate 10 having two colors. In order to form the double acrylic plate 10, first, a raw material and a catalyst are formed in a mold 16 at a predetermined ratio. The first liquid resin mixed with the resin is molded, and the mixing ratio of the raw material and the catalyst is most preferably 50:50, and when the molding is performed, the cooling water is circulated around the mold 16 to maintain 50 ° C. Molding for 3 to 4 hours in the state.

Subsequently, when the above process is completed, the temperature is raised to 80 ° C., and the first plate 12 is formed by heat treatment for 2 to 3 hours in this state.

When the first plate 12 is obtained as described above, the second liquid resin 13 is poured thereon, and the second liquid resin 13 preferably has a ratio of raw material to catalyst of 75:25. The second liquid resin 13 is also molded for 3 hours to 4 hours in a state of 50 ° C. like the first liquid resin, and then heat treated for 2 hours to 3 hours in a state of 80 ° C. to form the second plate 14. Form.

In the above, when the first plate 12 is formed and then the second plate 14 is formed, the first plate 12 and the second plate 14 are not formed of different objects. The first plate 12 and the second plate 14 are melt-bonded with each other to form a double acrylic plate 10 as one object.

That is, the first liquid resin 11 and the second liquid resin 13 is molded in the molding die 16 and heat is generated by the chemical reaction in the process of hardening, by the heat of Figure 1 As in the fourth process, the middle portion 15 of the double acrylic plate 10 is melted and bonded to form a single object.

In more detail, the second liquid resin 13 is formed on the first plate 12 and heat is generated by the chemical reaction of the second liquid resin 13 itself during the formation of the second plate 14. This heat melts the upper surface of the first plate 12, and as a result, the first liquid resin 11 and the second liquid resin 13 liquefied by melting the upper surface of the first plate 12. The mixture is hardened and formed as a single body rather than as the first plate 12 and the second plate 14, respectively.

In addition, the cooling water is circulated around the mold 16 in the above, the heat is generated by its own chemical reaction in the process of forming the first liquid resin 11 and the second liquid resin 13, the temperature rises If the temperature is raised in this way, the first and second liquid resins 11 and 13 are molded and bubbles are generated during the hardening process, thereby causing product defects. It is to adjust the temperature.

When the first plate 12 and the second plate 14 are melt bonded to each other by the above-described process, and the double acrylic plate 10 is completed, the colors of the front and rear surfaces of the double acrylic plate 10 are mutually different. As well as different, the color of the middle portion 15 is another color different from the front and rear of the double acrylic plate 10 will have an excellent aesthetic effect.

That is, since the middle portion 15 of the double acrylic plate 10 is a portion where the first plate 12 and the second plate 14 are melt-bonded, the middle portion 15 is formed of the first plate 12. Since colors and colors of the second plate 14 are mixed with each other, the colors of the first and second plates 12 and 14 are different from each other.

Therefore, when the double acrylic plate 10 according to the present invention is used as a signboard or an interior prop for an advertisement, an excellent effect can be expected, and it is preferable to coat colors on the surface or to adhere acrylic plates having different colors. In addition, since molding is performed by adding color from the molding step, color or form may not be deformed even in its use, and thus permanent use may be expected.

As described above, the present invention molds the first plate with the first liquid resin and pours the second liquid resin on the upper side thereof to form the second plate, wherein the first plate and the second plate are melt-bonded to each other to form one acrylic It is designed to have a double color on the board, and its aesthetic effect is excellent, and when used as a signboard or an interior accessory for advertisement, it is expected to increase the effect expected for the purpose, and even if exposed to sunlight, rain, or wind for a long time There is no change in color or form and it is designed to be permanently used.
