Description of each component used when manufacturing the functional resin panel of this invention which has the above characteristics is as follows.

Polystyrene (PS: polystyrene) is suitable for injection molding because of its excellent fluidity after melting, and is inexpensive, and is the most basic plastic for injection molding.

In addition, the polystyrene is divided into two types according to its type and properties, one of which is General Purpose Polystyrene (GPPS), and the other is High Impact Polystyrene (HIPS).

The general purpose (GPPS) is colorless, transparent and hard with high refractive index. It also has excellent electrical insulation (especially high frequency characteristics) and good dimensional stability of molded products. In addition, coloring is free, and surface treatment such as painting and printing is also easy. On the other hand, the disadvantages are brittle, weak to heat and weak to solvents.

On the other hand, HIPS is a synthetic rubber (SBR) added to GPPS, and the impact and tensile strength is improved, but the transparency is inferior, and if the blending amount is excessive, moldability, surface hardness, etc. are deteriorated. have. When used in addition to the above-mentioned impact resistance (HIPS) to manufacture the resin panel required by the present invention has the advantage that the impact resistance and tensile strength required by the resin panel is improved.

Charcoal, as is well known, has deodorization, humidity control, antiseptic effect and heat storage by adsorption. In addition, due to the adsorption function and deodorizing effect of the charcoal, the indoor humidity is controlled and odor is removed, and in particular, the toxic substances generated from building materials, such as phthalaldehyde, volatile organic compounds, ammonia gas, etc. Negative ions and far-infrared radiation induce human bioenergy activation to help health promotion. Therefore, when used in addition to the charcoal to produce a resin panel required by the present invention will enjoy the above effects.

Wood grass liquor is a pure photosynthetic natural energy made by refining and filtering wood grass liquor, which is produced by collecting and cooling smoke generated when carbonizing wood. Such wood vinegar has an antibacterial and bactericidal activity as well as a deodorizing function. Therefore, when the wood vinegar solution is used in addition to the resin panel required by the present invention, the indoor antibacterial and bactericidal action, as well as the deodorizing function of the room can be hygienically managed, of course, comfortable and It is possible to create a refreshing indoor atmosphere.

The active agent is used as a kind of lubricant aid that allows the polystyrene mixture to pass smoothly through the extruder when it is extruded in the extruder, and the stabilizer functions similar to the above-mentioned active agent, and is used for molding stability and melting stability. Foaming agents are those used for the foaming of polystyrene.

The functional resin panel manufacturing method according to the present invention by using each component having the characteristics as described above will be described in more detail by dividing each step as follows.

(Step 1)

The first step according to the present invention is a polystyrene chip containing charcoal 50 to 70% by weight, high polystyrene 29 to 47% by weight, the remainder is a mixture of woody liquor, activator, stabilizer, foaming agent as an adjuvant, the polystyrene chip Silver polystyrene resin is preferably mixed at a ratio of 70 to 85% by weight: 15 to 30% by weight of charcoal, but this is not a requirement but refers to a preferred ratio. It can also be used as the minimum content of charcoal should be at least 5% by weight based on the polystyrene resin and at most 60% by weight based on the polystyrene resin.

The reason is that if the weight of 5% by weight or less, the function (efficiency) of the above-described charcoal cannot be exhibited. If the content of the charcoal is 60% by weight or more, the function (efficiency) is improved.

Therefore, the polystyrene chip is preferably mixed at a ratio of 70 to 85% by weight of polystyrene resin: 15 to 30% by weight of charcoal, and if necessary, that is, at least 5% by weight of polystyrene resin with a minimum amount of charcoal, depending on the intended use. At most, 60 weight% or less may be sufficient with respect to polystyrene resin. In addition, the polystyrene resin prepared at the above ratio may be stirred, melted, extruded into a rod shape, cooled, and then processed (cut) into a chip shape.

The charcoal-containing polystyrene resin chip processed by the above method is not suitable for use as a panel by impact and tensile strength, so it is mixed with a high impact polystyrene (HIPS), mixed, melted and extruded. It is used for molding, and the amount of the high-polystyrene is added in a ratio of 29 to 47% by weight of high-polystyrene to 50 to 70% by weight of polystyrene resin chips.

The reason for this is to increase the impact strength and tensile strength of the resin by using the properties of the high-polystyrene described above, and when used at 29 wt% or less, the impact resistance and tensile strength of the resin panel required by the present invention reach the target values. If more than 47% by weight is used, impact properties and tensile strength are improved, but other moldability and surface hardness are lowered, so that high-polystyrene is 29 to 47 weight of high-polystyrene in 50 to 70 weight% of polystyrene resin chips. It is preferable to use it by adding%.

In addition, after the addition of high polystyrene 29 to 47% by weight to 50 to 70% by weight of the polystyrene resin chip as an adjuvant, the active agent and the molding to act as a lubricant for smoothing the woody liquor to further enhance the effect of charcoal and extrusion Stabilizers to enhance the stability of the melt and the melt, and a small amount of a blowing agent for inducing foaming of polystyrene is used.

The mixing ratio of the wood grass liquid, activator, stabilizer, and blowing agent used as the auxiliary agent is 0.1 to 1% by weight of the active agent, 0.05 to 0.5% by weight stabilizer, 0.05 to 0.5% by weight foaming agent, and the rest is wood grass liquid, 0.1% by weight or less of the active agent. When used, the lubricity is poor and the extrusion is not made smoothly. When used by more than 1% by weight, the lubricity is improved and the extrusion is smooth, but more than necessary.

In addition, when the stabilizer is used at 0.05% by weight or less, there is a problem in that the stability of the molding and the stability of melting are poor, and when 0.5% by weight or more is used, the stability of the molding and the stability of melting are improved, but this is also more than necessary. In addition, when the foaming agent is also used more or less than that, when the resin of the present invention is to be produced, there is a problem that foaming becomes more than necessary or less than necessary. Therefore, it is preferable to use the adjuvant to maintain the above mixing ratio.

Wood grass liquor is obtained when carbonizing wood as described above, which is used for the purpose of further enhancing the efficacy of charcoal, that is, antibacterial and bactericidal function, as well as deodorizing function, it is not necessary to use too much amount.

After the composition of each component by the method as described above, it is mixed using a mixer, the mixing method is stirred and mixed, the temperature of the mixer at this time is 90 ~ 110 ℃ and the mixing time is 15 to 30 minutes. The reason for setting the temperature of the mixer at 90 to 110 ° C is to dry the moisture contained in each component, and the reason for mixing time for 15 to 30 minutes is to secure sufficient drying time.

However, if the temperature of the mixer is 90 ℃ or less, the moisture drying time is long, so the productivity is lowered, if more than 110 ℃ polystyrene resin burns a problem occurs. Therefore, it is preferable that the temperature of a mixer shall be 90-110 degreeC.

(2nd step)

The second step according to the present invention is a step in which the mixture, which has been dried by the first step, is added to the melting furnace, stirred and melted, and the melt is cooled after extrusion molding into a desired shape using an extruder, wherein the melting temperature of the melting furnace is 140 ~ 190 ℃ is maintained because the melt of polystyrene resin is so weak that it is not suitable for extruding (the extruder has a load) at 140 ℃ or below. Too much molten state remains in the liquid state, which is also unsuitable for extrusion (no extrusion). Therefore, the melting temperature of the melting furnace is preferably 140 ~ 190 ℃ and it is preferable to stir for even mixing of the auxiliary agent during melting.

In addition, when the melting operation is completed, it is extruded by using an extruder, the extrusion method may be a plate, a rod, or any other required shape depending on the shape of the extruder outlet, and when the extrusion is completed, passing it through the cooling water To cool. At this time, the temperature of the cooling water may be maintained at 5 to 15 ° C, and preferably 9 to 10 ° C.

If the temperature of the cooling water is maintained below 5 ℃ may cause shrinkage deformation due to the rapid temperature difference with the extrudate, and if it is maintained above 15 ℃ the cooling rate is slow to immerse the extrudate in the cooling water for a long time The problem arises in productivity. And at 9-10 degreeC which is preferable temperature, it was great efficient in terms of cooling time and stability of cooling.

(3rd step)

The third step according to the present invention is a step of producing a desired pattern on the surface thereof when the cooling is completed by the second step, the pattern output is a metal film from the surface of the molded article 10 thereon Layer 20, patterned layer 30 Transparent surface protection layer 40 is formed sequentially, the reason for forming the metal film 20 is that the molded product 10 is a large amount of charcoal color When the patterned layer 30 is directly formed on the black color, the black color is transmitted through the patterned layer 30, thereby preventing the patterned layer 30 from producing the original color. do. Therefore, to prevent the black color from penetrating the patterned layer 30, the metal film 20 is formed.

In addition, when the patterned layer 30 is formed, a transparent surface protection layer 40, that is, a UV (ultraviolet) coating layer is formed on the surface of the patterned layer 30 to protect the patterned layer 30. . However, the formation of the metal film layer 20, the patterned layer 30, and the UV coating layer 40 may be performed by forming the UV coating layer 40 on one surface of the film F as shown in FIGS. 2A to 2C. By using the patterned layer 30 and the metal film layer 20 sequentially formed, the metal film layer 20 is transferred to the corresponding surface of the molded product 10, and after the transfer is completed, the film F Just remove it.

However, an adhesive is formed on the surface of the metal film layer 20 so that the metal film layer 20 is firmly adhered (transferred) to the corresponding surface of the molded product 10. And the said film F is a release paper.

As described above, when the process is finished from the first step to the third step, as shown in FIG. 1, the polystyrene molded article 10 containing char is sequentially formed on the upper part of the molded article 10. ), A patterned layer 30, a transparent surface protection layer 40 is formed.

On the other hand, the film (F) is to protect the surface of the transparent surface protection layer 40 to protect it from impact or scratches generated during handling, and when the intended construction or the desired work is finished, the film ( F) can be removed.

The present invention as described above is because the polystyrene resin contains a large amount of charcoal, because the characteristics of the charcoal deodorization and humidity control by the adsorption function and the antiseptic effect and heat storage function, as well as the indoor humidity control and odor removal, as well as building materials It removes the toxic substances generated from chloroform, volatile organic compounds, ammonia gas, etc., and makes the room comfortable. Also, it helps to promote health by inducing human's bioenergy activation by anion and far-infrared radiation.

In addition to the above effects, it is possible to produce a variety of colors and patterns on the panel surface has the effect of increasing the added value of the product.
