Description

난연 스티로폼 제조방법 및 제조장치{Preparation Method and Apparatus for Non-Flammable Styrofoam}Flame-retardant Styrofoam manufacturing method and manufacturing apparatus {Preparation Method and Apparatus for Non-Flammable Styrofoam}

본 발명은 난연 스티로폼 제조방법 및 제조장치에 관한 것으로서, 보다 상세하게는 스티로폼 내부에 난연제를 효율적으로 침투시킬 수 있는 새로운 난연 스티로폼 제조방법 및 제조장치에 관한 것이다.The present invention relates to a method and apparatus for manufacturing a flame-retardant Styrofoam, and more particularly, to a new method and apparatus for manufacturing a flame-retardant Styrofoam capable of efficiently penetrating a flame retardant into the Styrofoam.

발포 폴리스티렌(EPS, Expanded Polystyrene; 이하 관용명칭이 된 '스티로폼'이라 칭함)은 단열성, 완충성 및 가공성이 우수하므로 산업 전반에 걸쳐 널리 사용되고 있으며, 특히 제품을 보호하는 포장재나 건축용 단열재 및 흡음재로 널리 사용되는 유용한 품목이긴 하지만, 연화점이 낮아 열과 화기에 매우 취약하고 연소되는 과정에서 인체에 치명적인 유독가스가 발생하는 등 상당한 단점도 가지고 있기 때문에 근자에는 발포 스티로폼에 난연 기능성을 부여하기 위한 노력이 활발히 진행되고 있다. Expanded polystyrene (EPS, hereinafter referred to as 'Styrofoam' which has become a common name) is widely used throughout the industry because of its excellent thermal insulation, buffering properties and processability. In particular, it is widely used as a packaging material to protect products, insulation materials for construction, and sound absorption materials. Although it is a useful item to be used, it has considerable disadvantages such as being very vulnerable to heat and fire due to its low softening point, and toxic gas fatal to the human body during combustion. is becoming

이러한 발포플라스틱 제품을 건축 재료로 사용하기 위해, 난연성을 강화시키기 위해, 처음부터 수지에 난연성 물질을 첨가하여 비드(bead)를 만들고 이를 발포 성형하는 방식(예를 들면, 공개특허 2003-0042299), 발포된 비드에 난연성 물질을 코팅 및 혼합하고 열과 압력을 가해 성형하는 방식(예를 들면, 등록특허 10-1932077) 등이 기존에 널리 알려져 왔다. 그런데 양자 모두 공정이 복잡하고, 난연성 물질의 사용량 증가로 인해 무거워진다는 문제가 있고, 특히 후자는 비드를 가열융착할 때 발생하는 추가적인 발포에 의해 코팅되었던 난연성 물질의 몰림현상이 발생하면서 제품의 물성 및 난연성이 불균일해지는 단점이 있다.In order to use this foamed plastic product as a building material, in order to enhance flame retardancy, a method of foam molding by adding a flame retardant material to a resin from the beginning (for example, Patent Publication 2003-0042299), A method of coating and mixing a flame-retardant material on the foamed beads and molding by applying heat and pressure (eg, Patent Registration No. 10-1932077), etc. have been widely known in the past. However, both processes are complicated and have a problem that they become heavy due to an increase in the amount of flame retardant material used. In particular, in the latter case, the flame retardant material that has been coated by additional foaming occurs when the beads are heat-sealed, and the physical properties of the product And there is a disadvantage that the flame retardancy becomes non-uniform.

이에 가공 성형이 완료된 스티로폼을 유무기 난연제(難燃劑)로 코팅하거나 난연제를 내부에 침투시켜 난연화시키는 방법이 제시되었는데, 전자인 코팅법은 표면에만 난연제가 피복되어 있고 내부에는 난연제가 존재하지 않게 되므로, 난연성능이 매우 낮으며, 특히 외부에 노출되었을 때 시간 경과에 따라 표면의 난연제가 점차 탈리되면서 난연성이 급격히 감소되는 단점을 피할 수 없다. 따라서 후자인 침투법이 관심을 받고 있다.Accordingly, a method of coating the finished Styrofoam with an organic/inorganic flame retardant or penetrating the flame retardant inside to make it flame retardant was proposed. In the former coating method, the flame retardant is coated only on the surface and there is no flame retardant inside. Therefore, the flame retardant performance is very low, especially when exposed to the outside, as the flame retardant on the surface gradually desorbs over time, the disadvantage that the flame retardancy is rapidly reduced cannot be avoided. Therefore, the latter infiltration method is attracting attention.

등록실용실안 20-0387979(샌드위치패널 충전재용 난연재 주입장치)는 난연재의 강제 주입을 제시하고 있으나 주입관이 연결된 주입장치에 의한 선택적 국소부위의 주입으로 균일한 난연성을 갖기 어려운 단점이 있다. Registered Utility Plan 20-0387979 (flame retardant injection device for sandwich panel filler) suggests forced injection of flame retardant, but it has a disadvantage in that it is difficult to have uniform flame retardancy due to selective local injection by the injection device connected to the injection pipe.

등록특허 10-0780926(난연성이 우수한 발포플라스틱 성형체의 제조방법)에는 내부에 비드 간 공극이 형성되도록 제어된 성형폼을 제작하고 여기에 액상 난연액을 침투시키는 방법이 제시되어 있다. 그러나 이에 의하면 비드 간 일정한 크기와 분포의 공극을 형성하기 위해 더 복잡한 스티로폼 제조공정을 거쳐야 하는 문제가 있다.Registered Patent 10-0780926 (Manufacturing method of a foamed plastic molded body with excellent flame retardancy) proposes a method of manufacturing a molded foam controlled so that voids between beads are formed therein, and permeating a liquid flame retardant solution therein. However, according to this, there is a problem in that a more complicated Styrofoam manufacturing process is required to form pores of a uniform size and distribution between beads.

등록특허 10-0770977(진공타입의 난연제 투입시스템)은 스티로폼에 난연제투입흠집 형성장치와 난연제흡입장치 등으로 이루어진 난연 스티로폼 연속자동 제조설비를 제시하고 있다(도 1 참조). 이에 의하면 배치(batch)식이 적합한 난연 스티로폼 생산에 과도하게 복잡하고 거대한 구조의 설비이기 때문에 설비비가 과도하며, 실제 제품에도 다수의 '난연제투입흠집'이 있어 난연제 투입이 고르게 이루어지기 어렵고 제품표면에 손상이 있게 된다. 또한 공정상 하부에서 이동하는 스티로폼 위로 난연제가 상부에서 뿌려지고 있어 손실되는 난연제가 많을 뿐만 아니라 스티로폼 외곽부에서는 난연제가 흡입되기 전에 밖으로 흘러내리게 되어 부위에 따라 난연제 흡입밀도가 달라지게 된다. Registered Patent 10-0770977 (Vacuum type flame retardant injection system) proposes a continuous automatic manufacturing facility for flame retardant Styrofoam consisting of a flame retardant injection scratch forming device and a flame retardant suction device on Styrofoam (see FIG. 1). According to this, the equipment cost is excessive because it is an overly complex and huge structure facility for the production of flame retardant Styrofoam suitable for a batch type, and there are many 'flame retardant injection scratches' in the actual product, making it difficult to evenly inject the flame retardant and damage the product surface. there will be In addition, in the process, flame retardants are sprayed from the top onto the Styrofoam moving from the bottom, so there is not only a lot of flame retardant that is lost, but also flows down before the flame retardant is sucked in the outer part of the Styrofoam, so the flame retardant suction density varies depending on the part.

무엇보다도 본 발명자가 실제 진공 침투식 난연 스티로폼 제조장치를 이용하여 제조한 바, 하부에서 매우 강력하게 흡입(감압)을 하더라도 실제 난연제가 스티로폼 내부로 거의 침투되지 않아 코팅 수준에 머무는 것으로 확인되었다. 충분한 양의 난연제가 침투되도록 하기 위해서는 흡입을 위한 공정시간을 매우 길게 해야 하기 때문에 산업적으로 활용하기에는 '생산성'에 큰 문제가 있었다.Above all, it was confirmed that the present inventor hardly penetrated into the styrofoam and remained at the coating level even though the present inventors produced using the actual vacuum penetration type flame retardant styrofoam manufacturing apparatus, even if very strongly suctioned (reduced pressure) from the lower part. In order to allow a sufficient amount of flame retardant to penetrate, the process time for inhalation must be very long, so there was a big problem in 'productivity' for industrial use.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings and manufacturing examples. However, these drawings and production examples are only examples for easily explaining the content and scope of the technical idea of the present invention, and thereby the technical scope of the present invention is not limited or changed. It will be natural for those skilled in the art that various modifications and changes can be made within the scope of the technical spirit of the present invention based on these examples.

(1) 제조방법 발명(1) Invention of manufacturing method

전술하였듯이 본 발명은 압착침투단계 및 감압침투단계를 포함하는 난연제 침투식 난연 스티로폼 제조방법에 관한 것이다. 본 발명에서 압착침투단계와 감압침투단계는 순서가 바뀔 수 있다.As described above, the present invention relates to a flame retardant permeation type flame retardant styrofoam manufacturing method comprising a compression penetration step and a reduced pressure penetration step. In the present invention, the order of the compression permeation step and the reduced pressure permeation step can be changed.

본 발명에서 상기 압착침투단계는, 스티로폼의 일부분을 순차적으로 소정시간 소정 정도 압착했다가 압착해제하며, 압착되는 부분 전후에 스티로폼에 난연제를 가하는 단계이다. 난연제를 '가하는 방법'은 난연제의 물성에 따라 적하방법, 붓는 방법, 스프레이 방법, 코팅방법 등 임의의 적절한 방법 중의 어느 하나 일 수 있다.In the present invention, the compression penetration step is a step of sequentially pressing and releasing a portion of the Styrofoam for a predetermined time for a predetermined time, and adding a flame retardant to the Styrofoam before and after the compressed portion. The 'addition method' of the flame retardant may be any suitable method, such as a dripping method, a pouring method, a spraying method, and a coating method, depending on the physical properties of the flame retardant.

본 발명은 본 발명자들이 발견한 다음과 같은 현상을 기초로 도출된 것이다.The present invention was derived based on the following phenomena discovered by the present inventors.

① 성형된 스티로폼 그대로를 압착하면 스티로폼이 부서진다.① If the molded Styrofoam is pressed as it is, the Styrofoam is broken.

② 성형된 스티로폼 표면 전체에 액체를 가한 다음 압착하면 스티로폼 두께의 40~50%를 압착하더라도 부서지지 않는다. 즉, 액체와 만난 스티로폼은 취성(깨지는 특성)이 대폭 감소된다.② If liquid is added to the entire surface of the molded Styrofoam and then pressed, it will not break even if 40-50% of the thickness of the Styrofoam is compressed. That is, the brittleness (breaking property) of the Styrofoam that meets the liquid is greatly reduced.

③ 성형된 스티로폼 표면 전체에 액체를 가한 다음 압착했다가 압착을 해제하면 스티로폼은 즉시 처음 두께로 탄성적으로 복귀된다.③ After applying liquid to the entire surface of the molded Styrofoam, press and release the compression, and the Styrofoam immediately returns to its initial thickness elastically.

④ 표면 전체에 액체를 가한 스티로폼이 압착되었다가 압착이 해제되어 두께가 복귀될 때 스티로폼 표면의 액체가 빠르게 스티로폼으로 흡수된다.④ When the Styrofoam with the liquid applied to the entire surface is compressed and the compression is released and the thickness is restored, the liquid on the surface of the Styrofoam is quickly absorbed into the Styrofoam.

즉, 상기 압착침투단계는 이렇게 발견한 현상에 따라 난연제를 빠르게 스티로폼 내부로 흡수시키는 것이다. 순서대로 벌어지는 일을 설명하면, 먼저 스티로폼 표면에 난연제를 가하여 스티로폼의 취성을 감소시킨다. 이어서 일부분을 소정 정도 압착했다가 압착을 해제하면 스티로폼이 원상복귀되면서 내부가 감압상태가 된다. 이때 스티로폼 표면에 가해져 있던 난연제가 빠르게 흡수되는 것이다.That is, the compression penetration step is to quickly absorb the flame retardant into the Styrofoam according to the discovered phenomenon. To explain what happens in sequence, first, a flame retardant is added to the surface of the Styrofoam to reduce the brittleness of the Styrofoam. Then, when a portion is compressed to a certain extent and then the compression is released, the Styrofoam returns to its original state and the inside is in a decompressed state. At this time, the flame retardant applied to the Styrofoam surface is quickly absorbed.

본 발명에서 상기 감압침투단계는, 스티로폼의 일면을 감압하고 타면에 난연제를 가하는 단계로서 전술한 종래기술(등록특허 10-0770977)과 같은 개념으로 난연제가 스티로폼 내부로 침투되도록 하는 것이다.In the present invention, the pressure-reducing penetration step is a step of depressurizing one surface of the Styrofoam and adding a flame retardant to the other surface, so that the flame retardant penetrates into the Styrofoam with the same concept as in the prior art (Registration Patent No. 10-0770977).

이렇듯 본 발명에 의하면 단순히 감압에 의한 난연제 침투 이외에 스티로폼의 압착에 대한 회복탄력성을 활용하여서도 난연제 침투가 이루어진다. 따라서 종래 알려진 감압에 의한 침투의 문제점인 침투불량 문제가 해소되어 보다 완전한 난연성을 가지는 스티로폼을 제조할 수 있게 된다.As such, according to the present invention, flame retardant penetration is achieved by utilizing the resilience against compression of Styrofoam in addition to flame retardant penetration by simply decompression. Therefore, the problem of poor penetration, which is a problem of penetration due to reduced pressure, known in the prior art is solved, and it is possible to manufacture Styrofoam having more complete flame retardancy.

한편, 이렇게 압착침투단계와 감압침투단계를 거친 난연제가 침투된 스티로폼의 표면에는 과잉의 난연제가 남아있을 수 있다. 따라서 본 발명에서는 스티로폼 표면에 잔류하는 과잉의 난연제를 제거하는 제거단계; 및 과잉의 난연제가 제거된 스티로폼을 건조하는 건조단계;를 추가로 포함하는 것이 바람직하다.On the other hand, excess flame retardant may remain on the surface of the styrofoam infiltrated with the flame retardant that has undergone the compression penetration step and the reduced pressure penetration step. Therefore, in the present invention, the removal step of removing the excess flame retardant remaining on the surface of the Styrofoam; and a drying step of drying the Styrofoam from which the excess flame retardant has been removed.

제거단계에서는 통상 알려진 블레이드 또는 롤러를 활용할 수 있을 것이며, 건조단계에서는 열풍건조기 등을 이용할 수 있을 것이다.In the removal step, a commonly known blade or roller may be used, and in the drying step, a hot air dryer or the like may be used.

(2) 제조장치 발명(2) Invention of manufacturing equipment

또 다른 본 발명은 전술한 제조방법을 수행하기 위한 제조장치에 관한 것이다.Another invention relates to a manufacturing apparatus for carrying out the above-described manufacturing method.

이러한 본 발명에 의한 난연제 침투식 난연 스티로폼 제조장치의 일예를 도 2a에 개념적으로 도시하였다.An example of the flame retardant penetration type flame-retardant Styrofoam manufacturing apparatus according to the present invention is conceptually shown in FIG. 2A.

본 발명에 의한 제조장치는, The manufacturing apparatus according to the present invention,

(A) 가공될 스티로폼(F)이 안착되어 연속해서 또는 간헐적으로 이송되도록 하는, 다수의 관통공이 형성된 컨베이어벨트(10); (B) 상기 컨베이어벨트(10) 위에 설치되어 통과하는 스티로폼(F)의 일부분을 소정 정도 압착하는 압착부(20); (C) 상기 컨베이어벨트(10)의 저면에 설치되어 통과하는 스티로폼(F)에 감압을 제공하는 감압탱크를 포함하는 감압수단(30); 및 (D) 상기 압착부(20)의 전후 및, 상기 감압탱크 전단과 감압탱크에 대응되는 스티로폼(F)의 상면에 난연제를 가하는 난연제공급부(40);를 포함하는 침투식 난연 스티로폼 제조장치이다. 이때 상기 압착부(20)와 감압수단(30)의 설치 위치는 전후가 바뀌어도 관계없다.(A) the Styrofoam (F) to be processed is seated so as to be continuously or intermittently transferred, a conveyor belt 10 having a plurality of through-holes formed; (B) a compression part 20 installed on the conveyor belt 10 and compressing a portion of the Styrofoam (F) passing through it to a predetermined degree; (C) a decompression means 30 including a decompression tank installed on the bottom surface of the conveyor belt 10 and providing decompression to the styrofoam (F) passing through; and (D) a flame retardant supply unit 40 for applying a flame retardant to the front and rear surfaces of the compression unit 20 and to the upper surface of the Styrofoam (F) corresponding to the front end of the decompression tank and the decompression tank; . At this time, the installation positions of the compression unit 20 and the pressure reducing means 30 do not matter even if the front and rear are changed.

도면에서 볼 수 있듯이 상기 컨베이어벨트(10)는 스티로폼(F)과 감압수단(30) 사이에 개재된다. 따라서 감압수단(30)에 의한 감압이 스티로폼(F)에 가해질 수 있도록 상기 컨베이어벨트(10)에는 다수의 관통공이 형성되어 있다(도시 생략). 이때 컨베이어벨트(10)는 상기 감압수단(30)의 특성에 따라, 감압수단(30)이 연속작동식이면 연속작동하며, 감압수단(30)이 멈춤작동식이면 [이송-멈춤-이송-멈춤...]방식으로 간헐적으로 작동되도록 한다. 압착부(20)가 위치한 부분에는 압착부(20)가 작동하더라도 컨베이어벨트(10)가 늘어지거나 눌려지지 않도록 컨베이어벨트(10) 하면에 소정의 지지부(도시 생략)가 설치되는 것이 좋을 것이다. As can be seen from the drawings, the conveyor belt 10 is interposed between the Styrofoam F and the pressure reducing means 30 . Therefore, a plurality of through-holes are formed in the conveyor belt 10 so that the pressure reduction by the decompression means 30 can be applied to the Styrofoam F (not shown). At this time, according to the characteristics of the pressure reducing means 30 , the conveyor belt 10 operates continuously if the pressure reducing means 30 is a continuous operation type, and when the pressure reduction means 30 is a stop operation type [transfer-stop-transfer-stop] ...] to make it work intermittently. It is preferable that a predetermined support (not shown) be installed on the lower surface of the conveyor belt 10 so that the conveyor belt 10 is not stretched or pressed even when the compression unit 20 is operated.

본 발명에서 상기 압착부(20)는 난연제가 가해진 스티로폼(F)을 압축했다가 풀어줌으로써 그 순간 난연제가 스티로폼(F) 내부로 빠르게 흡수되도록 한다. 이때 압착부(20)는 주기적으로 상하이동하면서 압착하는 방식을 택할 수도 있을 것이지만, 도면에 예시된 것처럼 소정의 압력으로 이송되는 스티로폼(F)을 압축하는 압축롤러인 것이 바람직하다. In the present invention, the compression unit 20 compresses and releases the Styrofoam (F) to which the flame retardant has been applied, so that the flame retardant is rapidly absorbed into the Styrofoam (F) at that moment. At this time, the compression part 20 may adopt a compression method while periodically moving up and down, but it is preferably a compression roller that compresses the Styrofoam (F) conveyed at a predetermined pressure as illustrated in the drawing.

상기 감압수단(30)은 스티로폼(F)의 일면이 감압상태가 되도록 하고, 타면에 난연제를 가하여 압력차에 따라 난연제가 스티로폼(F) 내부로 침투되도록 한다. 감압수단(30)은 감압탱크와 진공펌프일 수 있는데 이 경우 감압관과 감압탱크 사이에 개폐스위치가 있는 것이 바람직하다(도시 생략). 한편, 상기 감압수단(30)에는 스티로폼(F)을 통과하여 낙하하는 난연제를 회수하는 회수관이 연결되는 것이 바람직하다. 이렇게 회수된 난연제는 폐기되거나 소정의 난연제 탱크로 회수되어 재활용된다. 난연제 회수관에도 개폐스위치가 있어서 감압수단(30)이 작동할 때는 회수관이 폐쇄되고, 정지했을 때는 개방되도록 하는 것이 바람직하다.The pressure reducing means 30 causes one surface of the Styrofoam (F) to be in a reduced pressure state, and a flame retardant is added to the other surface to allow the flame retardant to penetrate into the Styrofoam (F) according to the pressure difference. The pressure reducing means 30 may be a pressure reducing tank and a vacuum pump. In this case, it is preferable that there is an opening/closing switch between the pressure reducing pipe and the pressure reducing tank (not shown). On the other hand, it is preferable that a recovery pipe for recovering the flame retardant falling through the Styrofoam (F) is connected to the pressure reducing means 30 . The recovered flame retardant is either discarded or returned to a predetermined flame retardant tank for recycling. The flame retardant recovery pipe also has an opening/closing switch, so that when the pressure reducing means 30 operates, the recovery pipe is closed, and when it stops, it is preferable to open it.

본 발명에서 상기 난연제공급부(40)는 최소한 압착부(20) 전후 및 감압수단(30)의 전단과 감압수단(30)이 위치한 곳에 충분한 난연제가 공급되도록 한다.In the present invention, the flame retardant supply unit 40 ensures that sufficient flame retardant is supplied at least before and after the compression unit 20 and at the front end of the pressure reducing means 30 and the pressure reducing means 30 are located.

또 다른 본 발명에 의한 제조장치는, (A) 통과하는 스티로폼(F)의 일부분을 순차적으로 소정시간 소정 정도 압착했다가 압착해제하는 하나 또는 복수개 쌍의 압축롤러; (B) 스티로폼(F)의 저면에 직간접적으로 접하면서 감압하는 감압탱크를 포함하는 감압수단(30); 및 (C) 상기 롤러 전후 및, 상기 감압탱크 전단과 감압탱크에 대응되는 스티로폼(F)의 상면에 난연제를 가하는 난연제공급부(40);를 포함하는 것일 수 있다(도 2b 참조). 이때 역시 압축롤러와 감압수단(30)의 설치순서는 바뀔 수 있다.Another manufacturing apparatus according to the present invention comprises: (A) one or a plurality of pairs of compression rollers for sequentially compressing and releasing a portion of the Styrofoam (F) for a predetermined time for a predetermined time; (B) a decompression means 30 including a decompression tank for decompression while in direct or indirect contact with the bottom surface of the styrofoam (F); and (C) a flame retardant supply unit 40 for applying a flame retardant to the front and rear surfaces of the roller and the upper surface of the Styrofoam (F) corresponding to the front end of the decompression tank and the decompression tank (see FIG. 2b). At this time, the installation order of the compression roller and the pressure reducing means 30 may also be changed.

즉, 하나 또는 복수개 쌍의 압축롤러를 이용하여 상기 압축침투단계가 수행되도록 하는 것이다.That is, the compression penetration step is performed using one or a plurality of pairs of compression rollers.

이 경우 컨베이어벨트(10)는 압축롤러와는 분리되어 감압수단(30)에 설치될 수 있는데(도시된 예), 이때 감압수단(30)이 연속작동식이 아니라면 컨베이어벨트(10) 구조를 생략하는 것도 가능할 것이다.In this case, the conveyor belt 10 may be installed in the pressure reducing means 30 separately from the compression roller (example shown). At this time, if the pressure reducing means 30 is not a continuous operation type, the structure of the conveyor belt 10 is omitted. It will also be possible
