The present invention relates to a method for producing recycled rubber using recycled rubber such as waste tires.

산업이 고도로 발달하면서 자동차의 폐타이어, 에어백, 튜브, 컨베어벨트, 호스, 스폰지, 고무실, 의료용 고무제품, 공업용 고무제품, 폼러버, 라텍스침지제품, 공장폐고무, 기타 폐고무의 배출량이 비약적으로 증대되고 있는 반면에, 상기의 폐합성고무의 재활용률은 극히 적으므로 폐합성고무의 처리문제는 자원의 재활용이라는 측면과 환경 보존적인 측면에서 조속히 해결되어야 하는 문제로 대두되고 있다.With the development of the industry, automobile tires, air bags, tubes, conveyor belts, hoses, sponges, rubber seals, medical rubber products, industrial rubber products, foam rubber, latex immersion products, factory waste rubber, and other waste rubber On the other hand, since the recycling rate of the waste synthetic rubber is extremely small, the problem of disposal of the waste synthetic rubber has emerged as a problem to be solved promptly in terms of resource recycling and environmental conservation.

근래에는 폐합성고무를 재활용하기 위하여 폐합성고무를 분쇄한 후 이를 원료로 하여 보도블럭, 매트, 도로포장재 등으로 많이 사용하고 있는 실정이다. Recently, in order to recycle the waste synthetic rubber, the waste synthetic rubber is crushed and used as a raw material such as sidewalk blocks, mats and road paving materials.

그러나 폐합성고무를 재생하는 공정 중에서 탈황공정을 거치며 강도저하 및 신장율 저하 등과 같은 고무의 특성이 많이 저하되어 사용용도가 많이 제한되는 문제점이 있었다.However, during the process of regenerating waste synthetic rubber, there is a problem in that the use of the rubber is much limited because the characteristics of the rubber, such as strength reduction and elongation rate, are deteriorated.

더욱이 천연고무와 대형 폐타이어는 그나마 재생이 되고 있으나, 소형타이어와 합성고무류(SBR, BR, EPDM)는 재생을 하지 못하고 있는 실정이다.
Moreover, natural rubber and large waste tires are being recycled, but small tires and synthetic rubbers (SBR, BR, EPDM) cannot be recycled.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서 강도저하 및 신장율 저하 등과 같이 고무의 특성이 저하되는 문제점 없이 폐합성고무를 이용하여 천연 고무 특성을 그대로 유지하는 폐합성고무를 이용한 재생고무 제조방법을 제공하는 것이 본 발명의 목적이다.The present invention has been made in order to solve the above problems, the production of recycled rubber using waste synthetic rubber to maintain the natural rubber properties by using the waste synthetic rubber without the problem of deterioration of the rubber properties such as reduced strength and elongation It is an object of the present invention to provide a method.

상기와 같이 구성된 본 발명에 의한 폐타이어를 이용한 재생고무 제조방법은 강도저하 및 신장율 저하 등과 같이 고무의 특성이 저하되는 문제점 없이 폐합성고무를 이용하여 천연 고무 특성을 그대로 유지하는 재생고무의 원료로 제조할 수 있다.The method for producing recycled rubber using waste tires according to the present invention configured as described above is a raw material of recycled rubber that maintains natural rubber properties using waste synthetic rubber without problems such as deterioration in strength and elongation.

In addition, it is very difficult to recycle, so small tires and synthetic rubbers such as SBR, BR, and EPDM, which are not actually used, can be manufactured with high-quality recycled raw materials.

도 1은 본 발명에 의한 폐합성고무를 이용한 재생고무 제조방법을 공정별로 도시한 도면.1 is a view showing a process for producing recycled rubber using waste synthetic rubber according to the present invention for each process.

이하 본 발명에 의한 폐합성고무를 이용한 재생고무 제조방법에 대하여 상세히 설명한다.Hereinafter, a method for preparing recycled rubber using waste synthetic rubber according to the present invention will be described in detail.

본 발명에 의한 폐합성고무를 이용한 재생고무 제조방법은 고무스크랩 준비단계(S10), 조쇄단계(S20), 세쇄단계(S30), 오일 혼합단계(S40), 교반단계(S50) 및 성형단계(S60)로 구성된다.
Regenerated rubber manufacturing method using the waste synthetic rubber according to the present invention is a rubber scrap preparation step (S10), crushing step (S20), crushing step (S30), oil mixing step (S40), stirring step (S50) and molding step ( S60).

고무스크랩 준비단계(Rubber scrap preparation step ( S10S10 ))

종래의 폐합성고무를 이용한 재생고무 제조방법은 폐합성고무를 수집하고 폐타이어인 경우는 버스, 트럭용 대형 타이어와 승용차 타이어로 구분하였다.In the conventional method for manufacturing recycled rubber using waste synthetic rubber, waste synthetic rubber is collected, and in the case of waste tires, it is divided into large tires for buses and trucks and passenger car tires.

승용차 타이어와 대형 타이어는 사용조건이 상이하므로 천연고무와 SBR의 혼합비율에 차이가 있으며 승용차 타이어는 대형 타이어에 비해 SBR의 함량이 매우 높다.Passenger car tires and large tires have different conditions of use, so there is a difference in the mixing ratio between natural rubber and SBR. Passenger car tires have a higher content of SBR than large tires.

SBR은 가열하면 천연고무와 전혀 다른 작용을 하므로 재생하려는 고무중에 SBR의 함량 즉 전고무분에 대한 SBR의 비율을 일정하게 하여 재생고무의 품질을 균일하게 유지하도록 하기 위함이다.Since SBR has a completely different effect from natural rubber when heated, it is to maintain the quality of regenerated rubber uniformly by keeping the content of SBR in the rubber to be regenerated, that is, the ratio of SBR to total rubber.

그러나 본 발명은 이후 설명하는 분쇄단계와 오일혼합단계를 통해 원료 스크랩의 SRB의 함량과 상관없이 균일한 재생고무를 생산할 수 있으므로 승용차 타이어와 대형 타이어를 구분할 필요 없이 폐타이어를 수집하고 타이어 내부의 와이어를 제거한 후 물로 타이어를 세척하여 타이어에 포함된 흙 등의 이물질을 세척한다.However, the present invention can produce a uniform recycled rubber irrespective of the SRB content of the raw material scrap through the crushing step and the oil mixing step to be described later, so that the waste tires are collected without the need to distinguish between car tires and large tires and wires inside the tires. After removing the rinse the tire with water to wash the dirt and other foreign matter contained in the tire.

최근에는 카아카스에 와이어를 넣은 스틸타이어가 대부분이다 이러한 스틸타이어는 분쇄처리가 까다로울 뿐만 아니라 재생고무에 금속이 혼합되는 원인이 될 수도 있으므로 구분하여 처리하여야 한다.
In recent years, most steel tires are wired into carcass. These steel tires are not only difficult to grind, but may also cause mixing of recycled rubber with metal.

조쇄단계(Crushing stage ( S20S20 ))

준비된 고무스크랩을 분쇄하는 분쇄공정이다.It is a grinding process of grinding the prepared rubber scrap.

고무스크랩을 분쇄하는 목적은 고무스크랩을 다음 공정에서 취급이 용이하고 또한 고무스크랩에 오일과 열의 작용을 균등하고 효율좋게 작용되도록 고무스크랩을 입상 또는 분말상으로 성형하는 것이다.The purpose of crushing the rubber scrap is to shape the rubber scrap into granular or powder form so that the rubber scrap can be easily handled in the next process and the oil and heat act on the rubber scrap evenly and efficiently.

조쇄단계는 고무스크랩을 이후의 세쇄단계에서 사용될 수 있도록 크라카를 이용하여 고무스크랩을 1mm 크기 이하로 1차 분쇄하는 단계이다.The crushing step is a step of first crushing the rubber scrap to less than 1mm in size using Kraka so that the rubber scrap can be used in the subsequent crushing step.

이때, 고무스크랩을 기계적으로 분쇄할 때 기계열과, 고무스크랩 입자의 충돌 및 재료의 유동에 의한 전열작용에 의해서 열이 발생하면서 고무스크랩이 탈황된다.At this time, when the rubber scrap is mechanically crushed, the rubber scrap is desulfurized while heat is generated by the mechanical heat, the collision of the rubber scrap particles, and the heat transfer action of the material flow.

탈황이란 고무와 결합한 황을 실제로 제거한다는 의미가 아니고 고무의 망 가교된 것의 일부가 가교간의 사슬일부의 절단에 의한 해중합을 의미한다.Desulfurization does not mean the actual removal of sulfur bound to the rubber, but rather means depolymerization by part of the chain crosslinked between the crosslinks of the rubber.

그리고 조쇄단계에서 분쇄되는 고무스크랩의 온도를 150℃이하로 유지하도록 한다. And keep the temperature of the rubber scrap crushed in the crushing step to 150 ℃ or less.

고무스크랩은 200℃의 온도 이상으로 가열되면 강도와 신장율과 같은 고무 특유의 특성이 급격하게 저하된다. 특히, SBR의 경우 150℃ 이상의 온도에서는 경화되어 버리는 문제점이 있다.When the rubber scrap is heated above a temperature of 200 ° C., the rubber-specific characteristics such as strength and elongation rate are drastically lowered. In particular, in the case of SBR there is a problem that will be cured at a temperature of 150 ℃ or more.

상술한 바와 같이 고무스크랩을 기계적으로 분쇄할 때 열이 발생하게 되는데 상기 조쇄단계에서 고무스크랩을 분쇄할 때 냉각로울러를 사용하거나, 고무스크랩을 분쇄하는 크라카의 회전수를 조절하는 등의 방법을 통해 분쇄되는 고무스크랩의 온도를 150℃ 이하로 유지하도록 한다.As described above, heat is generated when the rubber scrap is mechanically crushed. A method such as using a cooling roller when grinding the rubber scrap in the crushing step or adjusting the rotational speed of the crusher that grinds the rubber scrap is used. Keep the temperature of the rubber scrap to be crushed through 150 ℃ or less.

또한, 상기 조쇄단계에서 금속검출기를 통해 고무스크랩에 포함된 금속물질을 걸러 내는 것이 바람직하다.
In addition, it is preferable to filter the metal material contained in the rubber scrap through the metal detector in the crushing step.

세쇄단계(Print step ( S30S30 ))

세쇄단계는 상기 조쇄단계를 통해 1mm 크기 이하로 분쇄된 고무스크랩을 26~40메시 크기의 고무분말로 분쇄하는 단계이다.The crushing step is a step of crushing the rubber scrap crushed to less than 1mm size through the crushing step into a rubber powder of 26 ~ 40 mesh size.

세쇄단계를 통해 고무스크랩을 입자크기와 입도분포가 고르고 안정적인 고무분말로 성형함으로써 양질의 재생고무를 제조할 수 있도록 한다.Through the crushing step, the rubber scrap is formed into a stable and stable rubber powder with a uniform particle size and particle size distribution, thereby producing high quality recycled rubber.

상기 조쇄단계에서와 같이 세쇄단계에서 분쇄되는 고무스크랩에서 기계열과, 고무스크랩 입자의 충돌 및 재료의 유동에 의한 전열작용에 의해서 열이 발생하면서 고무스크랩이 탈황된다.In the rubber scrap crushed in the crushing step as in the crushing step, the rubber scrap is desulfurized while heat is generated by electrothermal action by mechanical heat, collision of rubber scrap particles, and material flow.

상술한 바와 같이 고무스크랩은 200℃ 이상의 온도에서는 고무 특유의 여러 특성이 저하되므로 세쇄단계에서도 분쇄롤러의 회전수를 조절하거나, 냉각로울러를 사용하여 고무스크랩의 온도를 150℃ 이하로 유지하도록 한다.
As described above, the rubber scrap has various characteristics peculiar to the rubber at a temperature of 200 ° C. or higher, so that the number of revolutions of the grinding roller is adjusted even in the fine grinding step, or the cooling scrap is used to maintain the temperature of the rubber scrap at 150 ° C. or lower.

오일 혼합단계(Oil mixing step ( S40S40 ))

상기와 같이 조쇄단계 및 세쇄단계를 통해 26~40메시 크기로 성형된 고무분말에 아로매틱오일(Aromatic oil)(상품명:A2오일), 파라핀오일(P. oil), 나프텐 오일(N2 oil), 화이트오일 중 어느 하나 또는 둘 이상이 혼합된 오일을 혼합하는 오일 혼합단계이다.Aromatic oil (trade name: A2 oil), paraffin oil (P. oil), naphthenic oil (N 2 oil) in rubber powder molded into 26 ~ 40 mesh size through the crushing step and the crushing step as described above. ), One or two or more of the white oil is an oil mixing step of mixing the mixed oil.

분쇄된 고무분말 85~98중량%와, 아로매틱오일, 파라핀오일, 나프텐오일, 화이트오일 중 어느 하나 또는 둘 이상이 혼합된 오일 2~15중량%를 혼합함으로써 상기 오일들이 고무분활의 연화, 가소화, 팽윤 등의 연화작용에 의하여 천연고무와 유사한 정도로 강도와 신장율 등의 고무특성이 재생된다.
The oils soften the rubber powder by mixing 85 to 98% by weight of crushed rubber powder and 2 to 15% by weight of oil in which any one or two or more of aromatic oil, paraffin oil, naphthenic oil and white oil are mixed. By softening such as plasticization and swelling, rubber properties such as strength and elongation are regenerated to a degree similar to that of natural rubber.

교반단계(Stirring Step ( S50S50 ))

상기 오일 혼합단계를 통해 아로매틱오일, 파라핀오일, 나프텐오일, 화이트오일 중 어느 하나 또는 둘 이상이 혼합된 오일과 고무분말이 혼합된 혼합물을 교반기로 교반하는 단계이다.The oil mixing step is a step of stirring the mixture of the oil powder and rubber powder mixed with any one or two or more of the aromatic oil, paraffin oil, naphthenic oil, white oil with a stirrer.

상기 교반단계를 거치면 고무분말 입자가 서로 엉켜 마치 카스테라와 같은 상태로 가소화된다.
After the stirring step, the rubber powder particles are entangled with each other and plasticized in a state like a castella.

성형단계(Molding step ( S50S50 ))

상기 교반단계를 거친 고무분말을 로울러에 여러 번 반복 통과시켜서 입상의 고무가 없어질 때까지 이겨서 가소성과 점착성을 부여한다. The rubber powder passed through the stirring step is repeatedly passed through a roller several times until the granular rubber disappears to impart plasticity and adhesiveness.

상기와 같이 고무분말을 로울러로 여러 번 반복통과시키면 가소성과 점착성이 증가되어 시이트형태로 성형되고, 이를 드럼에 20~30mm 두께가 될 때까지 감는다. When the rubber powder is repeatedly passed through the roller as described above, plasticity and adhesiveness are increased to form a sheet, which is wound on the drum until it is 20 to 30 mm thick.

이후 이를 잘라서 타분, 칭량 및 포장하는 단계이다.
It is then cut and weighed, weighed and packaged.
