Description
본 발명은 트윈 압출기를 이용한 폐고무 재생방법에 관한 것으로 더욱 상세하게는 6mm 정도의 입자로 분쇄된 폐고무에 고무재생 오일 및 가소제를 혼합하여 전열(電熱)에 의한 열원장치 및 회전력이 조절될 수 있는 트윈 스크류의 압출기에 투입함으로써 압출기의 회전력에 의한 마찰응력과 토출압력의 압축으로 유황가교된 폐고무의 탈황온도 부분적으로 일정하게 유지 및 가열하여 연속적으로 탈황이루어지도록 하는 트윈 스크류 압출기를 이용한 폐고무 재생방법에 관한 것이다.The present invention relates to a waste rubber recycling method using a twin extruder, and more particularly, by mixing rubber regeneration oil and a plasticizer in waste rubber pulverized into particles of about 6mm, the heat source device and rotational force by electric heat can be controlled. Waste rubber using twin screw extruder, which is injected into twin screw extruder and keeps desulfurization temperature of sulfur-crosslinked waste rubber partially condensed by heating and frictional pressure by extruder's rotational force and compression of discharge pressure. It relates to a regeneration method.
일반적으로 재생고무는 가류된 고무를 물리적, 화학적으로 처리하여 다시 점착성과 가소성을 주어 원료고무 또는 미가류 혼합고무와 같은 용도로 사용하는데 이를 재생고무라 하며, 이러한 재생고무를 만드는 중요한 공정은 가류공정으로 이는 가류된 고무에 결합되어 있는 결합 유황을 제거하여 미가류 상태의 것으로 환원시키는 즉, 화학적으로 가역반응을 일으키게 하는 것인데, 이때 결합 유황의 가교를 절단시키기는 어렵다.In general, recycled rubber is used for the same purpose as raw material rubber or unvulcanized mixed rubber by giving tackiness and plasticity by physically and chemically treating the vulcanized rubber, which is called reclaimed rubber. This is to remove the bound sulfur bound to the vulcanized rubber to reduce it to an unvulcanized state, that is, to cause a chemically reversible reaction, wherein it is difficult to cut the crosslinking of the bound sulfur.
재생고무의 재료(원료)는 일반 산업용 용품에서 폐품된 것이나 고무공장내에서 모여진 잡고무를 원료로 하고 있으며 일반고무 제조시 재생고무를 단독 사용할 때키기는 곤란하며 신고무와 일정비율 혼합하여 원가를 낮추고 혼합작업을 용이하게 하는 목적으로 사용하는 일종의 유기충진제 역할을 하는 원료이기도 한다.The raw material of recycled rubber is scraped from general industrial supplies or raw rubber collected in a rubber factory, and it is difficult to use recycled rubber alone when manufacturing rubber. It is also a raw material that serves as a kind of organic filler used for the purpose of facilitating the treatment.
이러한 재생고무의 제조방법으로서는 대표적인 것으로 분쇄법과, 증해팬(PAN)법, 리크라맨트(Reclamate)법으로 이루어진다.Representative methods for producing such recycled rubber include a grinding method, a cooking pan (PAN) method, and a reclamate method.
즉, 분쇄법은 가류된 고무를 분쇄기 등에서 여러단계를 거쳐 미립자로 만들고, 이러한 미립자로 형성된 고무분을 가류공정으로 옮겨 탈류시키는데 분쇄법은 가류관과 같은 모양의 구조관에 넣고 밀폐시켜 탈류를 행하며, 이때 탈류제로서 송탄유를 쓰며 증기 10kg/cm 가압하에 행해짐으로써 탈류시간이 장시간 소요된다.That is, the pulverization method makes the vulcanized rubber into fine particles through several steps in a pulverizer, etc., and transfers the rubber powder formed from such fine particles to the vulcanization process to deflow. In this case, the desulfurization time takes a long time by using the coal oil as the desulfurizing agent, and is carried out under a pressure of 10 kg / cm of steam.
또한 증해팬법은 미립자보다 크기가 큰 입자로 분쇄한 것을 사용하며, 증해관이라 하는 이중벽의 수중관을 써서 탈류하는데, 탈류방법으로 알카리법과, 중성법이 있으며 알카리법은 고무를 수산화나트륨(NaOH)용액중에서 소량의 연화제를 가하여 가열 탈류하는 방법이며 중성법은 수산화나트륨 용액 대신 염화칼슘(CaCl2)용액이나 또는 염화아연(ZnCl2)용액을 사용하고 탈류는 18kg/cm2정도의 증기압으로 고무중 염류기 위의 용액에 의하여 가열 작용되어 용해 제거되며 가열후 세척, 탈수, 건조시켜 사상함으로써 화학제 세정 관계상으로 폐수발생이 많다.In addition, the cooking pan method is pulverized into particles larger in size than the fine particles, and it is deflowed using a double walled water pipe called a cooking pipe. The degassing method includes an alkali method and a neutral method, and the alkali method uses rubber as sodium hydroxide (NaOH). A small amount of softener is added to the solution for heating and dehydration. The neutral method uses calcium chloride (CaCl 2 ) solution or zinc chloride (ZnCl 2 ) solution instead of sodium hydroxide solution, and dehydration is 18 kg / cm 2 . The solution is heated and dissolved by the above solution. After heating, it is washed, dehydrated and dried to finish.
또한 리크라매트법은 역시 부분적으로 온도조절이 되는 리크라매트라하는 이중벽을 가진 스크류형의 압출기를 쓰면서 탈류를 하며 온도조절이 용이하여 단시간 탈류되고 이 방법은 연속 탈류되는 것이 특징이며, 탈류기 내부를 통하면서 5분내 압출 급냉시켜 사상함으로써 생산량이 소량이라 경제성이 없다.In addition, the rekramat method is degassed using a screw-type extruder having a double wall which is also partially temperature-controlled, and is easily deregulated for a short time due to easy temperature control, and this method is characterized by continuous degassing. Extruded and quenched in 5 minutes while passing through the inside, resulting in a small amount of production.
상기와 같이 재생고무의 제조방법에서 가장 널리 이용되는 것은 증해팬법이며, 이를 첨부된 도 1에 의해 보다 상세히 설명하면 다음과 같다.The most widely used in the production method of reclaimed rubber as described above is a cooking pan method, which will be described in more detail by the accompanying FIG.
먼저 폐고무를 6mm정도의 굵기로 분쇄하여 혼합조에 투입하고, 이 혼합조에 탈황을 촉진시킬 송탄유를 투입하여 충분히 고르게 혼합한 다음 이 송탄유가 혼합된 폐고무를 가류관에 투입하여 고압증기로 40∼50kg/cm2의 압력에서 1∼3시간 동안 가열하면서 탈황시키게 되며, 이 가류관을 통해 탈황된 폐고무를 냉각하고, 압연로울러를 사용하여 제련 및 정련함으로써 재생고무의 제조를 완료하게 된다.First, the waste rubber is pulverized to a thickness of about 6 mm and put into a mixing tank. In this mixing tank, pine oil to accelerate desulfurization is added and mixed evenly enough. Desulfurization is carried out by heating at a pressure of ˜50 kg / cm 2 for 1 to 3 hours. The desulfurized waste rubber is cooled through the vulcanizing tube, and smelting and refining is performed using a rolling roller to complete the production of regenerated rubber.
이러한 종래 재생고무의 제조방법에서는 가류관에서 40∼50kg/cm2의 고압증기로 탈황하는 과정에서 여러 종류의 혼합된 폐고무류에서 천연고무는 탈황의 효과를 어느 정도 기대할 수 있으나, 합성고무의 경우에는 탈황이 잘 이루어지지 않음으로써 폐합성고무가 연질로 되는 가소성(可塑性)을 유지하기 어렵게 된다.In the conventional method of manufacturing recycled rubber, natural rubber can be expected to have some effect of desulfurization in various kinds of mixed waste rubber in the process of desulfurization by high pressure steam of 40-50kg / cm 2 in a vulcanization tube. It is difficult to maintain plasticity in which the waste synthetic rubber becomes soft due to poor desulfurization.
즉, 가류관에서 합성고무류는 탈황온도점에서 일시적 가소화되며, 짧은 시간이 지나면 가소성이 떨어지면서 다시 경화가 지속되고, 단시간 가소성이 되는 점에서 신속히 정련 처리되어야하는 시간적 문제점이 발생된다.In other words, the synthetic rubber in the vulcanization tube is temporarily plasticized at the desulfurization temperature point, and after a short time, the plasticity decreases and the curing continues, and in the short time, the plasticity is required to be quickly refined in a short time.
또한 가류관에 투입되는 폐합성고무의 양은 용기의 용량에 제한되어 있어 연속적인 작업 및 자동화가 불가능할 뿐만 아니라 40∼50kg/cm2의 고압증기로 공급으로 열공급과정에서 유해한 악취와 증기가 발생되어 작업환경이 악화되며 환경오염 방지에 많은 자금이 소요되는 문제점이 있다.In addition, the amount of waste synthetic rubber put into the vulcanization pipe is limited to the capacity of the container, making continuous work and automation impossible, and supplying with high pressure steam of 40-50kg / cm 2 generates harmful odors and steam during the heat supply process. There is a problem that the environment is deteriorated and a lot of funds are required to prevent environmental pollution.
본 발명은 상기와 같은 종래의 문제점을 해소하기 위해 분쇄된 폐고무에 탈황을 촉진시킬 프로세스 오일을 첨가하여 충분히 혼합하고 상기 프로세스 오일이 혼합된 폐합성고무를 고온·고압으로 압출시키는 트윈 스크류 압출기를 경유하게 함으로써 기계적인 회전응력 및 마찰열을 이용하여 탈황점을 선택적으로 이루어지도록 한 것이다.The present invention is a twin screw extruder that is sufficiently mixed by adding a process oil to promote desulfurization to the pulverized waste rubber to solve the conventional problems as described above, and extruding the waste synthetic rubber mixed with the process oil at high temperature and high pressure By passing through it, the desulfurization point is selectively made using mechanical rotational stress and frictional heat.
그러므로 본 발명은 폐고무를 트윈 스크류 압출기를 경유하게 함과 동시에 히터에 의해 고온의 열을 가함으로서 트윈 스크류 압출기의 고회전에 의한 기계적 에너지와 히터의 발열에 의해 가소화 및 탈황시키게 되어 온도 및 압력조절이 정밀하여 폐고무가 탈황되는 가소점을 정확히 설정할 수 있으며, 폐고무가 트윈 스크류 압출기에 지속적으로 공급될 경우 작업의 중단없는 연속적인 재생고무 생산 자동화가 용이하여 인력을 절감할 수 있을 뿐만 아니라 냉각장치에 의해 압출시 인체에 유해한 가스의 생성을 방지하게 되어 작업환경의 개선은 물론, 환경오염을 예방할 수 있도록 한 것을 기술적 과제로 한다.Therefore, in the present invention, the waste rubber is passed through the twin screw extruder and at the same time the high temperature heat is applied by the heater to plasticize and desulfurize by mechanical energy due to the high rotation of the twin screw extruder and the heating of the heater to control the temperature and pressure. This precise setting allows precise setting of the plasticizer point at which waste rubber is desulfurized, and when waste rubber is continuously supplied to twin screw extruders, it is easy to automate continuous production of recycled rubber without interruption of work, thus saving labor and cooling. The technical problem is to prevent the generation of harmful gases to the body during extrusion by the device to improve the working environment as well as to prevent environmental pollution.
본 발명의 폐고무 제조방법은 폐고무를 6mm 정도의 굵기로 분쇄하는 분쇄공정과, 분쇄된 폐고무에 가소제를 투입하여 혼합하는 혼합공정과, 상기 가소제와 혼합된 폐고무를 연질로 만들고 탈황시키는 가소화 및 탈황공정과, 상기 탈황공정을 거쳐 가소화 및 탈황된 폐고무를 냉각시키는 냉각공정과, 냉각된 재생고무를 제련 및 정련공정을 거쳐 제조되는 폐고무의 제조방법에 있어서, 상기 가소화 및 탈황공정은 가소제가 고르게 혼합된 폐고무를 트윈 스크류 압출기를 경유하게 하되, 트윈 압출기의 외부에 설치된 히터의 탈황 온도를 250℃ 에서 유지시켜 트윈 스크류 압출기의 토출압력에 의한 기계적 에너지와 응력에 의해 가소화 및 탈황되도록 한 것에 특징이 있다.The waste rubber manufacturing method of the present invention is a grinding step of grinding waste rubber to a thickness of about 6mm, a mixing step of mixing by adding a plasticizer to the pulverized waste rubber, and the waste rubber mixed with the plasticizer to soften and desulfurized In the plasticizing and desulfurization process, a cooling process for cooling the waste rubber plasticized and desulfurized through the desulfurization process, and a method for producing waste rubber produced by smelting and refining the cooled regenerated rubber, And the desulfurization process by using a twin screw extruder to the waste rubber evenly mixed with the plasticizer, while maintaining the desulfurization temperature of the heater installed outside the twin extruder at 250 ℃ by the mechanical energy and stress caused by the discharge pressure of the twin screw extruder It is characterized by plasticization and desulfurization.
도 1은 종래 폐고무의 재생공정도.1 is a process for regeneration of conventional waste rubber.
도 2는 본 발명에 따른 폐고무의 재생공정도.2 is a recycling process of the waste rubber according to the present invention.
도 3은 본 발명에 사용되는 트윈 스크류 압출기의 개략적인 정단면도.3 is a schematic front sectional view of a twin screw extruder used in the present invention.
이하 본 발명의 구성 및 작용을 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 폐고무의 재생공정도이며, 도 3은 본 발명에 사용되는 트윈 스크류 압출기의 정단면도로서, 먼저 폐고무를 6mm정도의 굵기로 분쇄하여 혼합조에 투입하고, 상기 폐고무가 투입된 혼합조에 탈황을 촉진시키며 고무의 가공성을 용이하게 할 목적으로 고무분자간에 인력을 감소시켜 배합제의 분산을 활성화하기 위한 재생 오일 파라핀(paraffine)계, 아토마틱(aromatic)계 등의 가소제를 적정량 투입하여 70∼80℃에서 약 30분간 교반하여 충분히 고르게 혼합시킨다.Figure 2 is a recycling process of the waste rubber according to the present invention, Figure 3 is a front sectional view of a twin screw extruder used in the present invention, first crushed waste rubber to a thickness of about 6mm and put into the mixing tank, the waste rubber Plasticizers such as recycled oil paraffin and aromatic are used to reduce the attraction between rubber molecules to promote desulfurization and facilitate the processability of rubber into the mixing tank. A proper amount is added and stirred for about 30 minutes at 70 to 80 ° C., followed by mixing evenly.
상기의 과정에서 재생 오일이 고르게 혼합된 폐고무를 도 3에 도시된 트윈 스크류 압출기(10)의 호퍼(4)에 투입하게 되면 미도시된 동력전달장치에 의해 제 1 및 제 2 스크류(2)(3)가 반대 방향으로 회전함에 따라 호퍼(4)에 투입된 폐고무를 50∼120kg/cm2의 압력으로 압출하면서 이동하게 되고, 이때 히터(1a~1e)의 온도를 250℃범위에서 조절함에 따라 트윈 스크류 압출기(10)의 토출 압력에 의한 기계적 마찰응력 및 에너지와 히터히터(1a~1e)의 고온에 의해 가소화되면서 탈황된다.In the above process, when the waste rubber having the recycled oil is evenly mixed into the hopper 4 of the twin screw extruder 10 shown in FIG. 3, the first and second screws 2 are not driven by the power transmission device. As (3) rotates in the opposite direction, while moving the rubber extruded into the hopper (4) at a pressure of 50 ~ 120kg / cm 2 to move, at this time to adjust the temperature of the heater (1a ~ 1e) in the 250 ℃ range Accordingly, the desulfurization is plasticized by mechanical frictional stress and energy caused by the discharge pressure of the twin screw extruder 10 and the high temperature of the heater heaters 1a to 1e.
따라서 히터(1a~1e)를 사용하여 트윈 스크류 압출기(10)에 열을 가함으로써 정밀한 온도조절이 용이하게 되어 폐고무가 연질로 되는 가소성질을 정확히 유지할 수 있을 뿐만 아니라 구간별로 온도구배를 조절할 수 있게 됨으로써 가소화점은 점을 구간별로 정확히 설정 가능하게 된다.Therefore, by applying heat to the twin screw extruder 10 using the heaters 1a to 1e, precise temperature control is facilitated, and it is possible not only to accurately maintain the plasticity of waste rubber becoming soft, but also to adjust the temperature gradient for each section. By doing so, the plasticizing point can accurately set the point for each section.
또한 트윈 스크류 압출기(10)에 의해 압출 성형되는 재생고무는 토출구의 헤드에 설치된 냉각장치(5)에 의해 급냉되어 증기가 응축됨으로써 인체에 유해한 가스의 발생이 없게 되어 2차 오염이 발생되지 않으며, 또한 호퍼(4)를 통해 분쇄된 폐고무를 지속적으로 공급할 경우 재생공정에 있어 작업의 연속성을 기할 수 있어 이로 인해 균질품질의 향상은 물론, 자동화가 가능하여 인력감소로 인한 생산원가를 절감할 수 있게 되는 것이다.In addition, the regenerated rubber extruded by the twin screw extruder 10 is quenched by the cooling device 5 installed in the head of the discharge port and condensed vapor, there is no generation of harmful gases to the human body, there is no secondary pollution, In addition, continuous supply of crushed waste rubber through the hopper (4) can ensure the continuity of work in the regeneration process, thereby improving the homogeneous quality and automation, thereby reducing the production cost due to reduced manpower. Will be.
상기의 공정에서 트윈 스크류 압출기(10)를 경유함에 따라 가소화 및 탈황에서 연질로 토출되어진 폐고무는 일반적인 방법으로 냉각 후 압연로울러를 사용하여 제련 및 정련함으로써 폐고무의 제조를 완료하게 된다.In the above process, the waste rubber discharged softly from plasticization and desulfurization through the twin screw extruder 10 is smelted and refined using a rolling roller after cooling in a general manner to complete the manufacture of waste rubber.
이상에서 상술한 바와 같이 본 발명은 분쇄된 폐고무에 탈황을 촉진시킬 재생 오일 및 가소제를 첨가하여 충분히 혼합하고, 상기 프로세스 오일이 혼합된 폐고무를 고온·고압으로 압출시키는 트윈 스크류 압출기를 경유하게 함으로써 트윈 스크류 압출기의 토출 압력에 의한 기계적 에너지와 히터의 발열에 의해 가소화 및 탈황시키게 되어 온도 및 압력조절이 용이하여 폐고무가 연질로 되는 가소점을 정확히 설정할 수 있으며, 폐고무가 트윈 스크류 압출기에 지속적으로 공급될 경우 작업의 중단없는 연속적인 재생과 자동화가 용이하여 인력을 절감할 수 있을 뿐만 아니라 압출기 헤드에 설치된 냉각장치에 의해 인체에 유해한 가스의 생성이 억제되어 작업환경의 개선은 물론, 환경오염을 예방할 수 있는 효과가 있는 것이다.As described above, the present invention adds a regenerated oil and a plasticizer to promote the desulfurization to the pulverized waste rubber, and sufficiently mixes it, and passes through the twin screw extruder which extrudes the waste rubber mixed with the process oil at high temperature and high pressure. Therefore, it is plasticized and desulfurized by mechanical energy due to the discharge pressure of the twin screw extruder and heat generation of the heater, and it is easy to control the temperature and pressure so that the plasticizer point at which the waste rubber becomes soft can be set accurately. Continuous supply and continuous supply and continuous regeneration and automation are not only easy to save manpower, but also the generation of harmful gases to the human body is suppressed by the cooling device installed in the extruder head. It is effective to prevent environmental pollution.
