Description
본 발명은 인공대리석 성형재료의 제조장치 및 제조방법에 관한 것으로, 상세하게는 인공대리석 질감이 나는 시트상의 열경화성 성형재료를 사용하여 제품 표면의 질감과 무늬 발현이 우수한 인공대리석 성형재료의 제조장치 및 제조방법에 관한 것이다.The present invention relates to a manufacturing apparatus and a manufacturing method of artificial marble molding material, and in detail, using a sheet-like thermosetting molding material having artificial marble texture, and an apparatus for manufacturing artificial marble molding material having excellent texture and pattern appearance on a product surface; It relates to a manufacturing method.
일반적으로 인공대리석은 불포화 폴리에스테르 수지를 주재료로 사용하고, 실리카, 탄산칼슘, 수산화알루미늄 등의 충진제, 유리섬유 및 기타 첨가제 등을 혼합한 재료을 이용하여 제조하며 부엌 싱크대 상판, 욕실 카운타 판널, 욕조, 벽판넬 등으로 많이 이용되고 있다.In general, artificial marble is made of unsaturated polyester resin as a main material, and is made of a mixture of fillers such as silica, calcium carbonate and aluminum hydroxide, glass fiber and other additives, and is used for kitchen counter tops, bathroom counter panels, bathtubs, It is widely used as a wall panel.
불포화 폴리에스테르를 기재로하는 인공대리석의 성형재료를 제조하는 방법으로 BMC(Bulk Molding Compound)가 있다.There is a BMC (Bulk Molding Compound) as a method for producing a molding material of artificial marble based on unsaturated polyester.
BMC는 불포화 폴리에스테르 수지, 충진제, 기타 첨가제를 넣고 혼련한 후에 배치(batch)에 칼라 칩, 약 2mm의 유리섬유 단편(chop)을 넣고 함께 니더(kneader)를 이용하여 혼련하여 만든 벌크상의 성형재료를 사용한다. 이러한 벌크상의 성형재료는 덩어리 형태이기 때문에 덩어리 하나 하나를 적당량 만큼의 몰드(mold)에 올려놓고 프레스 성형을 한다. 따라서, 금형에 충진 작업시 여러번에 걸쳐 작업이 이루어지는 단점이 있다. 또한, 덩어리 형태의 제품이라서 작업시 다루기가 불편할 뿐만 아니라 규격이 큰 인공대리석을 제작하기에는 작업성이 저하되고, 유리섬유를 혼련하는 과정에서 유리섬유의 가닥이 풀려 물성이 떨어지게 되며, 색상을 결정하는 칼라 칩의 몰림현상과 함께 성형품 강도가 약해지는 단점이 있다.BMC is a bulk molding material made by adding unsaturated polyester resin, filler, and other additives and kneading, and then mixing color chips and glass fiber chops of about 2 mm in a batch and kneading together using kneaders. Use Since the bulk molding material is in the form of a lump, each mass is put into an appropriate amount of mold and press-molded. Therefore, there is a disadvantage that the operation is performed several times during the filling operation on the mold. In addition, the product in the form of agglomerate is not only inconvenient to handle when working, but also to reduce the workability to produce a large artificial marble, the glass fiber is released in the process of kneading the glass fiber, the physical properties are deciding, There is a disadvantage that the strength of the molded part is weakened along with the phenomena of the color chip.
한편 인공대리석 성형재료로서 시트형상으로 제조하는 SMC는 도 1에 도시한 바와 같이 불포화 폴리에스테르 수지의 혼합물들을 상·하면에 위치하는 필름의 마주보는 위치에 각각 얇게 도포시키고, 하면에 도포된 혼합물에 유리섬유를 짧게 분쇄한 단편을 뿌리는 방식으로 생산된다. 이와 같이 연속적인 시트형상으로 형성되면 적당량의 시트를 여러 장 겹쳐 올려놓은 후에 프레스로 압축 성형하여 성형품을 연속적으로 제조할 수 있고, 판상이나 표면적이 넓은 성형품 생산에 있어 작업성이 용이하고 제품별 차이가 적은 장점이 있으나, 인공대리석의 질감 및 색을 결정하는 칼라 칩을 혼합물에 넣을 수가 없고 고점도의 혼합물은 강화제(유리섬유)의 함침성이 나빠 인공대리석 성형재료로서 부적합한 단점이 있다.Meanwhile, SMC, which is manufactured in a sheet form as an artificial marble molding material, is applied to the mixture applied to the lower surface by thinly applying the mixture of unsaturated polyester resins to the opposite positions of the films located on the upper and lower surfaces, as shown in FIG. Produced by sprinkling short pieces of glass fiber. If the sheet is formed in this way, it is possible to manufacture the molded product continuously by stacking an appropriate amount of sheets several times and then compression molding with a press. Although there is little advantage, color chips, which determine the texture and color of artificial marble, cannot be put in the mixture, and a mixture of high viscosity has a disadvantage of being inadequate as an artificial marble molding material due to poor impregnation of the reinforcing agent (glass fiber).
이와 같은 단점을 해결하기 위한 본 발명의 목적은 SMC와 같은 시트형상으로서 칼라 칩을 자유롭게 투입 및 조절하여 다양한 색상을 갖으며, 제품 표면의 질감과 무늬 발현이 우수한 인공대리석 성형재료의 제조장치 및 제조방법을 제공함에 있다.An object of the present invention for solving the above disadvantages is a sheet shape such as SMC has a variety of colors by inserting and adjusting the color chip freely, manufacturing apparatus and manufacturing of artificial marble molding material excellent in the appearance and texture of the product surface In providing a method.
본 발명의 다른 목적은 인공대리석의 색상을 결정하는 칼라 칩을 홈이 파여진 롤러를 이용하고 롤러의 회전을 조절함으로써 칼라 칩의 투입량을 조절할 수 있는 인공대리석 성형재료의 제조장치 및 제조방법을 제공함에 있다.It is another object of the present invention to provide an apparatus and method for manufacturing an artificial marble molding material which can control the amount of color chip input by using a grooved roller of a color chip for determining the color of the artificial marble and adjusting the rotation of the roller. Is in.

이하, 본 발명의 구성을 도면을 참조하여 자세히 설명한다.Hereinafter, the configuration of the present invention will be described in detail with reference to the drawings.
도 2는 본 발명에 따른 인공대리석 제조장치의 평면도이고, 도 3은 본 발명의 일실시예에 의한 칼라 칩 투입장치의 사시도이다.2 is a plan view of the artificial marble manufacturing apparatus according to the present invention, Figure 3 is a perspective view of a color chip input device according to an embodiment of the present invention.
본 발명에 사용한 인공대리석 성형재료는 총 중량을 기준으로 불포화 폴리에스테르 수지 20 내지 25중량%, 실리카, 탄산칼슘 및 수산화알루미늄 등의 충진제 40 내지 50중량%, 대리석, 폐기물 및 천연 파쇄물 등의 첨가제 5 내지 10중량%의 기본 혼합물에 유리섬유 10 내지 15중량%, 칼라 칩 5 내지 25중량%을 각각 혼합시킨 것을 이용한다.Artificial marble molding material used in the present invention is 20 to 25% by weight unsaturated polyester resin based on the total weight, 40 to 50% by weight filler, such as silica, calcium carbonate and aluminum hydroxide, additives such as marble, waste and natural crushed material 5 10 to 15% by weight of the base mixture of 10 to 15% by weight of the glass fiber, 5 to 25% by weight of the color chip is used.
도 2에 도시한 바와 같이, 유리섬유와 칼라 칩을 제외한 인공대리석 성형재료의 기본 혼합물은 서로 마주보고 회전하는 한 쌍의 함침롤러(1) 상부에 형성된 투입부(3)를 통하여 각각의 함침롤러(1)의 상에 토출된다.As shown in Fig. 2, the basic mixture of the artificial marble molding material excluding the glass fiber and the color chips is impregnated rollers through an input part 3 formed on the pair of impregnated rollers 1 facing each other and rotating. It is discharged on (1).
또한 함침롤러(1) 사이의 상부에는 유리섬유를 일정한 크기, 바람직하게는 약 1인지의 크기로 절단하는 커터가 장착된 커팅롤러(4)를 통과시켜 절단된 유리섬유 단편이 기본 혼합물에 투입된다.In addition, the glass fiber fragments cut by passing through the cutting roller (4) equipped with a cutter for cutting the glass fiber to a certain size, preferably about 1 size in the upper portion between the impregnation roller (1) is introduced into the basic mixture. .
그리고, 각 함침롤러(1)의 상부에는 도 3에 도시한 바와 같이 칼라 칩을 보관하는 칩호퍼(21)와 표면에 일정한 간격으로 다수의 홈(25)이 형성된 스케터롤러(23)가 칩호퍼(21)의 하부에 거의 맞닿도록 설치된다.As shown in FIG. 3, the chip hopper 21 for storing the color chips and the scatter roller 23 having a plurality of grooves 25 formed at regular intervals on the surface of the impregnating roller 1 are chips. It is installed so as to abut the lower part of the hopper 21.
따라서, 칩호퍼(21)에 보관되는 칼라 칩이 칩호퍼(21)의 하부와 맞닿는 스케터롤러(23)의 표면에 형성된 홈(25) 중에 모여지고, 스케터롤러(23)의 회전에 의해 홈에 모여진 칼라 칩이 함침롤러(1) 상에 공급되는 혼합물에 낙하된다. 이때, 스케터롤러(23)를 저속을 회전시키면 혼합물에 낙하되는 칼라 칩의 량이 적어지고, 스케터롤러(23)를 고속으로 회전시키면 혼합물에 공급되는 칼라 칩의 량을 많아진다.Therefore, the color chips stored in the chip hopper 21 are collected in the grooves 25 formed on the surface of the scatter roller 23 which abuts against the lower portion of the chip hopper 21, and are rotated by the scatter roller 23. The color chips collected in the grooves fall on the mixture supplied on the impregnation roller 1. At this time, rotating the scatter roller 23 at a low speed reduces the amount of color chips falling into the mixture, and rotating the scatter roller 23 at high speed increases the amount of color chips supplied to the mixture.
이와 같이, 함침롤러(1)에 인공대리석 성형재료의 주재료인 불포화 폴리에스테르 혼합물에 유리섬유 단편 및 칼라 칩 등이 투입되면, 함침롤러(1)는 서로 반대방향으로 회전되어 불포화 폴리에스테르 혼합물에 유리섬유와 칼라 칩이 강제 함침되어 함침롤러(1) 하방으로 낙하시킨다.As such, when glass fiber fragments and color chips are introduced into the unsaturated polyester mixture, which is the main material of the artificial marble molding material, the impregnating roller 1 is rotated in the opposite direction to the glass to the unsaturated polyester mixture. Fiber and color chips are impregnated to fall below the impregnation roller (1).
그 후, 함침롤러(1)의 하방으로 낙하된 혼합물은 함침롤러(1)의 하방으로 낙하된 혼합물은 2개의 보조롤러(5)에 의해 2개의 방향으로 나누어져 하나는 상부 필름(11)의 하면에 부착되고, 다른 하나는 하부 필름(9)의 상면에 각각 부착된다.Thereafter, the mixture dropped downward of the impregnation roller 1 is divided into two directions by the two auxiliary rollers 5 so that the mixture dropped downward of the impregnation roller 1 is one of the upper films 11. It is attached to the lower surface, and the other is attached to the upper surface of the lower film (9), respectively.
혼합물들이 상·하부 필름(11,9)에 부착되면 일정한 높이의 시트형상이 되도록 조절롤러(13)에 의해 하나로서 합쳐지고, 하나의 시트형상으로 제조된다.When the mixtures are attached to the upper and lower films 11 and 9, they are combined as one by the adjusting roller 13 so as to form a sheet of constant height, and are manufactured in one sheet form.
이와 같이 시트형상의 성형재료가 형성되면, 형성된 성형재료를 이송롤러(15)들에 의해 일정한 모양을 유지한 체로 이송된다. 이송롤러(15)는 시트형상의 성형재료를 이송하기 위하여 성형재료의 상·하부에 각각 위치한다.When the sheet-like molding material is formed as described above, the formed molding material is transferred to the sieve maintaining a constant shape by the transfer rollers 15. The feed rollers 15 are located at the upper and lower portions of the molding material, respectively, in order to transport the sheet-shaped molding material.
이때, 이송롤러는 이송속도를 제어하는 콘트롤러(미도시)에 연결되어 콘트롤러의 제어에 따라 이송속도를 제어함으로써 성형재료의 두께를 조절할 수 있는데, 이송롤러(15)의 이송속도를 저속으로 유지하면 이에 대응하는 상·하부 필름(11,9)의 이동속도가 저속으로 유지되고 필름(11,9)에 부착되어 쌓이는 혼합물의 량이 증가되어 성형재료의 두께가 증가되다. 또한, 이송속도를 높으면 상·하부 필름(11,9)의 이동속도가 빠르게 되어 필름(11,9)에 부착되는 혼합물의 량이 상대적으로 감소되어 성형재료의 두께가 상대적으로 작게 된다.At this time, the feed roller is connected to a controller (not shown) for controlling the feed rate to adjust the thickness of the molding material by controlling the feed rate according to the control of the controller, if the feed rate of the feed roller 15 is maintained at a low speed Correspondingly, the moving speeds of the upper and lower films 11 and 9 are kept at a low speed, and the amount of the mixture deposited on the films 11 and 9 is increased to increase the thickness of the molding material. In addition, when the feeding speed is high, the moving speed of the upper and lower films 11 and 9 is increased, so that the amount of the mixture attached to the films 11 and 9 is relatively reduced, and the thickness of the molding material is relatively small.
이와 소정의 이송롤러의 이송속도에 의해 소정의 두께를 갖도록 조절된 성형재료는 일정한 넓이를 갖는 포장장치(30)로 이송되어 필요한 두께로 포장된다. 이때, 두꺼운 두께를 갖는 인공대리석은 포장장치(30)에 여러장의 성형재료를 겹쳐 놓고 프레스 성형으로 제조할 수 있다.The molding material adjusted to have a predetermined thickness by the feeding speed of the predetermined conveying roller is conveyed to the packaging device 30 having a predetermined width and packed to the required thickness. In this case, the artificial marble having a thick thickness may be manufactured by press molding by placing a plurality of molding materials on the packaging device 30.
마지막으로, 포장된 성형물은 숙성실(40)에서 숙성된 후에 제품으로 완성한다.Finally, the packaged molding is finished in a product after it is aged in the aging chamber 40.

이상에서 살펴본 바와 같이, 본 발명에 의해 조제된 인공대리석 성형재료는 SMC와 같은 시트형상으로 제작되며 칼라 칩을 자유롭게 투입 및 조절할 수 있어 다양한 색상을 갖도록 할 수 있다.As described above, the artificial marble molding material prepared by the present invention may be manufactured in a sheet shape such as SMC, and may have various colors by freely inserting and adjusting color chips.
또한, 인공대리석 성형재료 중에서 인공대리석의 색상을 결정하는 칼라 칩을 홈이 파여진 롤러를 이용하고 롤러의 회전을 조절함으로써 칼라 칩의 투입량을 조절할 수 있다.In addition, the amount of color chips can be adjusted by using a grooved roller for the color chips for determining the color of the artificial marble among the artificial marble molding materials and adjusting the rotation of the rollers.
또한, 이송롤러를 통과하는 성형재료의 이송속도를 조절하여 필름에 부착되는 혼합물의 두께를 조절함으로써 다양한 두께를 갖는 인공대리석 성형재료를 제조할 수 있다.In addition, it is possible to manufacture the artificial marble molding material having a variety of thickness by controlling the thickness of the mixture attached to the film by adjusting the conveying speed of the molding material passing through the feed roller.
그리고, 제조된 성형재료를 시트형상의 인공대리석 성형재료를 금형위에 원하는 두께로 놓고 프레스 성형함으로써 다양한 크기의 인공대리석을 얻을 수 있다.Then, the manufactured molding material is formed by pressing the sheet-shaped artificial marble molding material to a desired thickness on a mold, and obtaining artificial marble of various sizes.
