본 발명은 실리콘 수지의 재생방법에 관한 것으로, 보다 상세하게는 다양한 용도로 사용한 후 폐기되는 실리콘 수지를 미세 분쇄하여 재활용할 수 있도록 하는 실리콘 수지의 재생방법에 관한 것이다.The present invention relates to a method for regenerating a silicone resin, and more particularly, to a method for regenerating a silicone resin to finely grind and recycle the discarded silicone resin after use in various applications.
일반적으로 실리콘 수지는 튜브, 패킹, 전선, 광섬유등과 더불어 밀폐제 또는 접착제로서 창유리 틀, 욕조, 냉동고 등에 사용되며 전자부품, 내한성ㆍ내열성의 전자회로의 코팅재료로 널리 사용되는 것이다.In general, silicone resins are used in windowpanes, baths, freezers, etc. as sealants or adhesives, along with tubes, packings, wires, and optical fibers, and are widely used as coating materials for electronic components, cold-resistant and heat-resistant electronic circuits.
따라서 건축현장이나 공장등에 사용되고 난 후 회수되는 폐 실리콘 수지를 처리함에 있어서 상기 폐 실리콘 수지는 실온에서 겔(gel)상태로 존재하므로 이 폐 실리콘 수지를 파쇄할 경우 입자가 크기 때문에 재활용이 불가능하여 소각하게 되었다. 이에 따라 폐 실리콘 수지를 소각할 경우 연소되는 폐 실리콘 수지에서 발생되는 매연으로 인해 환경오염을 초래하는 문제점이 있었다.Therefore, in treating waste silicone resin recovered after being used in construction sites or factories, the waste silicone resin exists in a gel state at room temperature, so when the waste silicone resin is crushed, it is impossible to recycle because of large particles. Was done. Accordingly, when the waste silicone resin is incinerated, there is a problem of causing environmental pollution due to the smoke generated from the waste silicone resin that is burned.
따라서 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 다양한 용도로 사용한 후 폐기되는 실리콘 수지를 미세 분쇄하여 재활용할 수 있도록 하는 실리콘 수지의 재생방법을 제공하는데 목적이 있다.Therefore, the present invention has been invented to solve the above problems, and an object of the present invention is to provide a method for regenerating a silicone resin which enables fine grinding of the silicone resin discarded after use for various purposes.
상기와 같은 목적을 달성하기 위한 본 발명에 따른 실리콘 수지의 재생방법은 폐 실리콘 수지를 소정크기로 분쇄하는 초기 단계와, 소정크기로 분쇄된 폐 실리콘 수지를 일정 온도이하로 동결건조시켜 고형화하는 단계와, 고형화 된 폐 실리콘 수지를 미세 분쇄하는 주 분쇄 단계와, 분쇄 된 폐 실리콘 수지 분말을 체 진동기를 통해 일정 이하의 입자크기를 갖는 실리콘 수지 분말을 분리 채취하는 단계로 구성되는 것을 특징으로 한다.Recycling method of the silicone resin according to the present invention for achieving the above object is an initial step of grinding the waste silicone resin to a predetermined size, and the step of solidifying by lyophilizing the waste silicone resin ground to a predetermined temperature or less And a main grinding step of finely pulverizing the solidified waste silicone resin, and separating and extracting the pulverized waste silicone resin powder and collecting the silicon resin powder having a particle size of less than a predetermined size through a sieve vibrator.
이하, 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings in detail as follows.
도 1은 본 발명에 따른 실리콘 수지의 재생방법을 나타낸 순서도이다.1 is a flowchart illustrating a regeneration method of a silicone resin according to the present invention.
일반적으로 건축현장이나 공장등에서 사용하고 난 겔(gel)상태의 폐 실리콘 수지를 소정의 크기로 절단기등을 이용하여 절단하게 되면 약 5 ~ 10mm정도의 입자 크기를 가지게 된다. 즉 상기와 같은 폐 실리콘 수지는 입자크기가 미세하지 못하므로 재활용이 불가능하였다.In general, when the waste silicone resin in a gel state used in a construction site or a factory is cut to a predetermined size using a cutter or the like, it has a particle size of about 5 to 10 mm. That is, the waste silicone resin as described above could not be recycled because the particle size was not fine.
따라서 본 발명은 폐 실리콘 수지를 재활용하기 위해 먼저 폐 실리콘 수지를 소정크기로 초기 분쇄를 하게 된다(S10). 이때 폐 실리콘 수지를 분쇄하기 위해 커터날, 절단기등을 사용하는 것이 바람직하다. Therefore, in the present invention, in order to recycle the waste silicone resin, the waste silicon resin is initially ground to a predetermined size (S10). At this time, it is preferable to use a cutter blade, a cutter, or the like to grind the waste silicone resin.
그리고 소정크기로 분쇄된 폐 실리콘 수지를 일정 온도이하로 동결건조시켜 고형화하게 된다(S20).Then, the waste silicon resin pulverized to a predetermined size is solidified by freeze-drying below a predetermined temperature (S20).
즉 겔(gel)상태의 폐 실리콘 수지는 냉동기를 통해 일정 온도에 따라 서서히 냉각되는 것이다. 즉 상기 냉동기는 상기 폐 실리콘 수지를 동결건조시키도록 그 내부의 온도를 영하 85도 이하로 하는 것이 바람직하다.That is, the gel waste silicone resin is gradually cooled at a predetermined temperature through a freezer. That is, it is preferable that the temperature inside the freezer be below minus 85 degrees so as to freeze-dry the waste silicone resin.
따라서 상기와 같은 동결건조 단계를 통해 실온에서 겔(gel)상태로 존재하는 폐 실리콘 수지는 고형화되는 것이다.Therefore, the waste silicone resin present in a gel state at room temperature is solidified through the lyophilization step as described above.
그 다음 동결건조과정을 통해 고형화 된 폐 실리콘 수지를 미세 분쇄하는 주 분쇄를 하게 된다(S30).Next, the main grinding is performed to finely grind the solidified waste silicone resin through the freeze-drying process (S30).
즉 냉동기를 통해 고형화 된 폐 실리콘 수지를 미세 분쇄하도록 분쇄기를 사용하는 것이 바람직하다. 따라서 상기와 같은 분쇄작업에 의해 폐 실리콘 수지 분말을 얻게 되는 것이다.That is, it is preferable to use a grinder to finely grind the solidified waste silicone resin through a freezer. Therefore, the waste silicone resin powder is obtained by the pulverizing operation as described above.
그 다음 분쇄 된 폐 실리콘 수지 분말을 체 진동기를 통해 일정 이하의 입자 크기를 갖는 실리콘 수지를 분리 채취하게 된다(S40).Then, the pulverized waste silicone resin powder is separated through a sieve vibrator to separate and collect a silicone resin having a particle size of less than (S40).
즉 체 진동기를 통해 폐 실리콘 수지 분말의 입자 크기가 0.01 ~ 0.1mm정도의 크기를 갖는 폐 실리콘 수지 분말을 채취하여 재활용할 수 있게 되는 것이다.That is, through the sieve vibrator, the waste silicone resin powder having a particle size of about 0.01 to 0.1 mm may be collected and recycled.
이와 같이 상기 S40단계에서 사용되는 체 진동기는 본 건 출원일 이전에 이미 공개된 기술이므로 이에 대한 구체적인 구성과 작동에 대한 설명은 생략하기로 한다.As described above, the sieve vibrator used in the step S40 is already disclosed before the filing date of the present application, so a detailed description of the configuration and operation thereof will be omitted.
상기와 같은 단계를 통해 미세 입자의 실리콘 수지 분말을 얻게 됨으로써 실리콘 수지를 제조하는데 필요한 재료로 재활용되어 재료절감의 효과를 갖는 것이 다. By obtaining the silicon resin powder of the fine particles through the above steps it is recycled to the material required to manufacture the silicone resin has the effect of reducing the material.
한편 미세 분쇄되어 재활용이 가능한 실리콘 수지 분말이 있는 반면에 입도가 크기 때문에 재활용할 수 없는 실리콘 수지 분말이 체에 남게 되는 것이다.On the other hand, there is a finely pulverized silicone resin powder that can be recycled, while the silicone resin powder, which cannot be recycled because of a large particle size, remains in a sieve.
따라서 실리콘 수지 분말을 분리 채취하는 단계(S40)를 통해 체에 남아 있는 상기 실리콘 수지 분말을 회수하여 경화제의 투입을 통해 응고시킨 후 응고된 상기 실리콘 수지 분말을 상기 초기 분쇄(S10)하는 단계에 공급하는 단계(S50)를 더 포함하는 것이다.Therefore, the silicon resin powder is collected and solidified through the addition of a curing agent through the step of separating and collecting the silicone resin powder (S40), and then the solidified silicone resin powder is supplied to the initial grinding step (S10). It further comprises the step (S50).
즉 체에 남아 있는 실리콘 수지 분말에 경화제를 투입하여 분말간의 공극을 메워 경도를 높일 수 있는 것이다. 특히 상기 경화제는 분말을 경화하는 과정에서 상기 경화제가 가지고 있는 휘발성에 의해 날아가는 성질을 가지고 있는 것이다.That is, by adding a curing agent to the silicone resin powder remaining in the sieve can fill the voids between the powders to increase the hardness. In particular, the curing agent has a property of flying by the volatility of the curing agent in the process of curing the powder.
따라서 응고된 실리콘 수지 분말은 전술한 초기 분쇄 단계(S10)와, 일정 온도 이하로 동결건조시켜 고형화하는 단계(S20), 미세 분쇄하는 주 분쇄단계(S30), 체 진동기를 이용하여 분리 채취하는 단계(S40)등을 반복하여 분말의 입자 크기가 0.01 ~ 0.1mm의 크기를 갖게 되어 재활용하게 되는 것이다.Therefore, the solidified silicone resin powder is the initial grinding step (S10) described above, the step of freezing-drying to a predetermined temperature or less solidifying step (S20), fine grinding the main grinding step (S30), the step of separating and using a sieve vibrator Repeating (S40) and the like will have a particle size of 0.01 ~ 0.1mm to be recycled.
이상에서 설명한 바와 같이 본 발명에 따른 실리콘 수지의 재생방법은 다양한 용도로 사용한 후 폐기되는 실리콘 수지를 미세 분쇄하여 재활용할 수 있다.As described above, the regeneration method of the silicone resin according to the present invention may be recycled by finely pulverizing the silicone resin discarded after use for various purposes.
또 폐 실리콘 수지를 재활용함으로써 환경오염 방지와 재료절감등의 효과도 있다.Recycling the waste silicone resin also has the effect of preventing environmental pollution and reducing materials.
본 발명은 첨부된 도면을 참조하여 바람직한 실시예를 중심으로 기술되었지 만 당업자라면 이러한 기재로부터 본 발명의 범주를 벗어남이 없이 많은 다양한 자명한 변형이 가능하다는 것은 명백하다. 따라서 본 발명의 범주는 이러한 많은 변형의 예들을 포함하도록 기술된 청구범위에 의해서 해석되어져야 한다.Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the invention from this description. Therefore, the scope of the invention should be construed by the claims described to include examples of many such variations.
