Abstract
Description
본 발명은 에어컨 컴프레서용 방진(防塵)고무의 제조방법에 관한 것이고, 더욱 상세하게는 170℃의 온도에서 가황처리를 하며, 황과 촉진제 외에 카본(carbon), 탄소칼슘(CaCO₃) 등을 첨가하며 탄성중합체(elastomer)로 형성되어 원래의 모양으로 되돌아오는 성질(복원성)이 있고, 질기며 잘 닳지 않고 화학약품에 잘 견디는 좋은 탄성중합체를 가질 수 있는 방진고무의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing dustproof rubber for air conditioner compressor, and more particularly, to vulcanization at a temperature of 170 ° C., in addition to sulfur and accelerators, carbon, carbon calcium (CaCO₃) and the like are added. The present invention relates to a method for manufacturing a dustproof rubber which is formed of an elastomer and has a property (resilience) to return to its original shape, and which can have a good elastomer that is tough and wear-resistant and well resistant to chemicals.
상기와 같이 우수한 탄성중합체가 가져야 할 화학적 성질로서는 분자량이 크고, 중합체 사슬이 유연성이 있으며, 극성과 구조의 불규칙성을 조절할 수 있어야하며, 수많은 고무제품의 제조에 사용될 수 있는 합성고무는 일반적으로 유화 중화반응에 의해 제조된다.As the chemical properties of the excellent elastomers as described above, the molecular weight is large, the polymer chains are flexible, the polarity and the structure irregularities must be controlled, and the synthetic rubbers that can be used for the production of numerous rubber products are generally emulsified. Prepared by reaction.
그리고 주요 합성고무는 스티렌-부타디엔고무(SBR:스티렌과 부타디엔의 공중합체), 니트릴고무(NBR:부타디엔과 아크릴로니트릴의 공중합체), 부틸고무(이소부틸렌과 2∼3%의 이소프렌 또는 다른 불포화탄화수소의 공중합체), 클로로프렌고무(클로로프렌의 중합체), 다황화 고무(디할로겐화에틸렌과 알카리성 다황화물로부터 합성)등이 있으며 스테레오 고무, 불소 고무 등도 쓰이고 있다.The main synthetic rubbers are styrene-butadiene rubber (SBR: copolymer of styrene and butadiene), nitrile rubber (NBR: copolymer of butadiene and acrylonitrile), butyl rubber (isobutylene and 2-3% isoprene or other Copolymers of unsaturated hydrocarbons), chloroprene rubber (polymers of chloroprene), polysulfide rubbers (synthesized from dihalogenated ethylene and alkaline polysulfides), and stereo rubbers and fluorine rubbers.
상기의 중화반응에 의한 중합체 생성에서, 예상 가능하고 바람직한 성능 특성을 갖는 중합체를 제조하기 위해 후처리된 중합체의 분자량 및 중합체 균일도 등의 변수의 조절에 따라 좌우될 수 있다.In the production of polymers by the above neutralization reaction, it may depend on the control of variables such as molecular weight and polymer uniformity of the post-treated polymers in order to prepare polymers having predictable and desirable performance characteristics.
또한 고무를 매우 낮은 온도에서 아주 길게 잡아 늘렸을 때 어느 정도 결정도를 갖기는 하지만 이와 같은 특성 때문에 표면 응집성이 생기게 되며, 변형이 되지 않은 상태에서는 분자들의 규칙성이 없어지게 되는 단점이 있다.In addition, when the rubber is stretched for a very long time at a very low temperature, it has a degree of crystallinity, but due to such a property, surface cohesion occurs, and there is a disadvantage that the regularity of the molecules is lost in the unmodified state.
그리고 상기의 설명과 같은 니트릴 고무 제조방법으로 특허출원(97-036022호)된 내용은 아크릴로니트릴과 1,3-부타디엔을 수성 유화액에서 공중합 반응시키므로써 합성될 수 있다는 설명과 이러한 단량체를 중합시킨 후, 수성 유화액으로 부터 중합체를 회수하는 것이 물론 필요하고 니트릴 고무함유 유화액으로부터 니트릴고무를 회수하는 개선된 방법에 관한 것으로 그 방법은 니트릴 고무함유 유화액에 산화방지제를 첨가하여 안정화 니트릴 고무 유화액을 제조하고, 안정화 니트릴 고무 유화액에 염산을 첨가하여 액상과 니트릴 고무조각으로 이루어진 응고된 니트릴 고무 슬러리를 제조하고, 응고된 니트릴 고무 슬러리의 액상으로부터 니트릴 고무조각을 분리시키고, 니트릴 고무 조각을 세척수에 혼합시켜 니트릴 고무 재슬러리를 제조하고, 니트릴 고무 재슬러리의 PH를 약 5내지 약 8범위로 조정하고, 니트릴 고무재 슬러리의 세척수로부터 니트릴 고무 조각을 분리시켜 유화액으 부터 회수되는 니트릴을 얻고자 하는데 그 목적을 두고 있다.In addition, the contents of the patent application (97-036022) in the nitrile rubber production method as described above can be synthesized by copolymerizing acrylonitrile and 1,3-butadiene in an aqueous emulsion and polymerizing these monomers. Thereafter, it is necessary, of course, to recover the polymer from the aqueous emulsion, and to an improved method for recovering nitrile rubber from the nitrile rubber-containing emulsion, wherein the method is prepared by adding an antioxidant to the nitrile rubber-containing emulsion to prepare a stabilized nitrile rubber emulsion. Hydrochloric acid was added to the stabilized nitrile rubber emulsion to prepare a solidified nitrile rubber slurry consisting of liquid and nitrile rubber pieces, to separate the nitrile rubber pieces from the liquid phase of the solidified nitrile rubber slurry, and to mix the nitrile rubber pieces with the wash water. Manufacture rubber ash sludge, knit Adjusting the PH of the rubber material in the slurry ranges from about 5 to about 8, and by separating the nitrile rubber pieces from the wash water of a nitrile rubber material slurry has its object to obtain the nitrile which is recovered from the emulsion coming from.
상기의 니트릴(nitrile)은 시아노 화합물이라고도 하며, 분자구조는 시아노기(-C=N)와 탄소원자가 결합한 분자구조를 가지는 유기화합물로 니트릴은 카르복시산의 산소원자를 질소원자로 치환시킨 중성물질이다.Nitrile is also called a cyano compound. The molecular structure is an organic compound having a molecular structure in which a cyano group (-C = N) and a carbon atom are bonded. Nitrile is a neutral substance in which an oxygen atom of carboxylic acid is substituted with a nitrogen atom.
아크릴로니트릴은 시안화수소와 아세틸렌 또는 산화에틸렌을 반응시켜 얻거나 촉매 존재 하에서 암모니아와 프로필렌을 반응시키는 암모니아 산화에 의해 얻는다.Acrylonitrile is obtained by reacting hydrogen cyanide with acetylene or ethylene oxide or by ammonia oxidation which reacts ammonia and propylene in the presence of a catalyst.
상기 아크릴로니트릴은 합성 고무 및 열가소성 수지 등을 포함한 다양한 종합물질의 중요한 구성성분이고, 몇몇 니트릴은 촉매 존재 하에 카르복시산을 암모니아와 가열하여 만드는 것으로 상기 과정은 천연지방과 기름에서 니트릴 추출하는 방법이고, 니트릴은 합성수지 및 섬유의 연화제로 사용되는 화합물의 제조에 사용하게된다.The acrylonitrile is an important component of various synthetic materials including synthetic rubbers and thermoplastic resins, and some nitriles are made by heating carboxylic acid with ammonia in the presence of a catalyst. The process is nitrile extraction from natural fats and oils, Nitrile is used in the preparation of compounds used as softeners in synthetic resins and fibers.
상기와 같이 가황된 중합체로 제공되는 경우, 고무 또는 엘라스토머는 가황되어 후처리된 제품으로의 가공을 촉진시키는 많은 형태를 취할 수 있다. 비가황된중합체는 조각형태, 곤포형, 고체 블록형 또는 입방형 등의 많은 다른 형태로 제공될 수 있다.When provided in a vulcanized polymer as described above, the rubber or elastomer can take many forms that are vulcanized to facilitate processing into a post-treated product. The unvulcanized polymer can be provided in many other forms, such as in the form of pieces, bales, solid blocks, or cuboids.
또한, 합성되어지는 유화액으로부터 유화액 고무를 회수하기 위해 사용되는 염산 응고법으로부터 또 다른 문제점이 발생할 수 있다.In addition, another problem may arise from the hydrochloric acid coagulation method used to recover the emulsion rubber from the emulsion to be synthesized.
그리고 응고 후에 중합체에 잔류하는 잔여 산은 중합체의 부식증가를 포함하여 상당한 문제점을 야기시킬 수 있으며, 중합체 내의 산 존재는 또한 가황 속도에 역효과를 미칠 수 있고, ph가 낮은 중합체는 중성 내지 알칼리 ph의 중합체보다 더욱 느린 속도로 가황된다.And the residual acid remaining in the polymer after solidification can cause significant problems, including increased corrosion of the polymer, the presence of acid in the polymer can also adversely affect the vulcanization rate, and low pH polymers are neutral to alkaline pH polymers. Vulcanization at a much slower rate.
따라서 이러한 가황 속도의 감소는 바람직하지 않은데, 이는 상업적인 조작에서 종종 병목 구간이 되는 고무 경화에 필요한 시간을 증가시키기 때문이고, 또한 응고, 유화액에 첨가되는 산의 양이 변할 수 있으므로 적어도 부분적으로 불확실성이 발생되는 단점이 있다.This reduction in vulcanization rate is therefore undesirable because it increases the time required for rubber curing, which is often a bottleneck in commercial operation, and also at least partially uncertainty as the amount of acid added to the coagulation and emulsion can vary. There is a disadvantage that occurs.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로서, 예비의 비제조 혼합 단계에서 아래의 고무 조성물(가)과 혼합될 원료(나)를 혼합시키는 수단과, 다음 후속의 제조 혼합 단계에서 (다)의 화합물을 첨가하여 복합 보강재와 함께 하나 이상의 추가 보강 촉진제를 함유하는 고무 조성물을 제조하는 수단으로 하여 에어컨 컴프레서용 방진고무을 제공함에 그 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, means for mixing the raw material (b) to be mixed with the rubber composition (a) below in the preliminary non-manufacturing mixing step, and the following subsequent manufacturing mixing step It is an object of the present invention to provide a dustproof rubber for an air conditioner compressor as a means of preparing a rubber composition containing at least one additional reinforcing accelerator together with the composite reinforcing material by adding the compound of (C).

Accelerator (ACC-M) 4. Accelerator (S) to accelerate the vulcanization process of rubber or process at low temperatures To make it happen.
그리고 상기의 조성물에 함유된 카본(carbon)은 고무제품의 강화제와 건조 피막의 은폐력이 큰 검은 색소로 인쇄용 잉크, 페인트, 먹지 등에 사용한다.In addition, the carbon contained in the composition is a black pigment having a large hiding power of a reinforcing agent and a dry film of a rubber product, and is used for printing inks, paints, and paper.
또한 보호막, 플라스틱, 전지회로의 저항기도 쓰이며 강화 충전제로 사용하여 내마멸성을 크게 할 수 있으며, 유조차 병원차 같은 자동차에 쓰이는 타이어는 정전하가 바퀴에 축전되는 것을 방지하기 위해 카본블랙(carbon black)을 첨가하여 고무의 전기 전도도를 크게 한다.It is also used as a protective film, a resistor of plastics and battery circuits, and can be used as a reinforcing filler to increase abrasion resistance.In addition, tires used in automobiles such as hospital cars use carbon black to prevent electrostatic charges from accumulating on the wheels. To increase the electrical conductivity of the rubber.
상기 카본블랙(carbon black)입자는 보통 구형이며 흑연보다 규칙성이 작은 결정성 물질이고, 카본 블랙은 3,000℃에서 장시간 가열하면 흑연으로 변할 수 있고, 지금까지 알려진 대단히 미세한 입자로 된 물질 중에서 카본 블랙은 제조공정에 따라 입자의 크기를 다양하게 변화시킬 수 있다.The carbon black particles are crystalline materials which are usually spherical and have a lower regularity than graphite, and carbon black can be converted into graphite after prolonged heating at 3,000 ° C. Silver can vary the size of the particles in accordance with the manufacturing process.
또한 상기의 조성물에 함유된 오일(D-4)은 유화제의 기능을 가지고 있으며, 조성물을 이루는 고무와 카본에 혼합되어 일정한 온도까지 가열되어져 상기의 고무와 카본을 순차적인 열역학적 혼합 단계까지 수행하고, 이때 둘 이상의 혼합 단계는 약 170℃의 온도에서 이루어질 수 있다.In addition, the oil (D-4) contained in the composition has a function of an emulsifier, is mixed with the rubber and carbon constituting the composition is heated to a constant temperature to perform the rubber and carbon to the sequential thermodynamic mixing step, In this case, two or more mixing steps may be performed at a temperature of about 170 ° C.
이때 둘 이상의 혼합 단계 사이의 고무 조성물의 중간 냉각은 약 40℃ 미만의 온도로 제공된다.The intermediate cooling of the rubber composition between two or more mixing steps is then provided at a temperature of less than about 40 ° C.
상기의 조성물에 함유된 탄소칼슘(CaCO₃)은 유기화합물이 산화되거나 분해되어 생기는 물질로 독특한 성질을 가지고 있으므로 특별한 용도로 사용되는데 있어서 상기에서는 고무의 마모성을 더욱 강화시키고자 사용하였다.Calcium carbon (CaCO₃) contained in the composition is a material produced by oxidizing or decomposing organic compounds, and has a unique property, so that it is used for a special purpose.
따라서 상기의 조성물의 일부인 고무에 카본, 탄소칼슘, 오일을 유화액으로 하여 중합 반응시키므로서 합성될 수 있다.Therefore, it can be synthesized by polymerizing the carbon, carbon calcium, oil to the rubber which is a part of the composition as an emulsion.
또한 원료제는 1.가류제(ZnO, ST/A) 2.노화방지제(3P,Ble-65) 3.노화방지제In addition, the raw material is 1. vulcanizing agent (ZnO, ST / A) 2. anti-aging agent (3P, Ble-65) 3. anti-aging agent
(RD) 4.접착부여제로 이루어져 고무의 가황처리 공정을 촉진시키거나 낮은 온도에서도 공정이 진행될 수 있도록 하였다.(RD) 4. It consists of an adhesive agent to accelerate the vulcanization process of rubber or to allow the process to proceed even at low temperatures.
위와 같이 원료제의 함유성분인 가류제(ZnO, ST/A)의 역할은 고무의 탄성과 저항력을 크게 하고, 용매에도 녹지 않게 하였다.As above, the role of the vulcanizing agent (ZnO, ST / A), which is a component of the raw material, increases the elasticity and resistance of the rubber and does not dissolve in the solvent.
그리고 상기의 노화방지제(3P,Ble-65),(RD)는 원료제에 함유되어 시간의 경과에 따라 고무가 변화되는데 이는 실온에서 공기 중에 있는 산소와 이들 물질이 결합하는 과정인 자동산화를 억제하며, 고무의 탄성을 감소시키고, 점질물과 같은 불필요한 물질들이 생성되는 것을 지연시킬 수 있다.And the antioxidants (3P, Ble-65), (RD) is contained in the raw material and the rubber changes over time, which inhibits the automatic oxidation which is a process of combining these substances with oxygen in the air at room temperature And may reduce the elasticity of the rubber and delay the generation of unnecessary materials such as viscous materials.
접착부여제(RD)는 서로 분리된 물질의 표면을 붙여 결합시키는데 쓰이는 물질로 영구적으로 접착시킬 수 있도록 하고, 내열성, 불용성이며, 화학변화를 하지 않는 한 변형되지 않는다.Adhesion agents (RD) are materials used to bond and bond the surfaces of materials separated from each other. They can be permanently bonded, heat resistant, insoluble, and unmodified unless chemically changed.
따라서 위와 같은 기능을 갖는 원료재들은 조성물이 일정한 형태로 변형되었을 때 상기의 원료재인 가류제, 노화방지제, 접착부여제를 투입시켜 조성물이 물리적으로 상호 혼합이 발생되도록 한다.Therefore, the raw materials having the above function is to put the vulcanizing agent, anti-aging agent, gluing agent as the raw material when the composition is transformed into a certain form so that the composition is physically mixed with each other.
상기 원료제는 다수의 복합물 특유의 성분과 구조에 의해 작용이 되므로 인하여 원료재는 조성물의 가황화를 돕게 된다.Since the raw material is acted on by the components and structures unique to a plurality of composites, the raw material helps to vulcanize the composition.
또한 상기의 화합물은 다수개의 촉진제로 형성되며, 고무의 가황처리공정을 촉진시키거나 낮은 온도에서도 공정이 일어날 수 있게 하는 기능이 있다.In addition, the compound is formed of a plurality of accelerators, and has the function of promoting the vulcanization process of the rubber or allowing the process to occur even at low temperatures.
이와 같이 가황처리 과정에서 촉진제는 황이 황과 반응하는 것보다 고무와 더 빠르게 반응할 수 있는 화합물로 전환되며, 또 다른 가능성은 촉진제가 먼저 고무와 반응해서 고무를 황과 빠르게 결합하는 형태로 변환시키는 것이다.As such, during the vulcanization process, the promoter is converted to a compound that can react with rubber faster than sulfur reacts with sulfur. Another possibility is that the promoter first reacts with the rubber to convert the rubber into a form that bonds quickly with sulfur. will be.
따라서 본 발명의 고무 조성물은 다양한 목적과 형태로 사용될 수 있으며, 예를 들면 에어컨 컴프레서의 하부에 장착되어 콤프레서에서 발생되는 소음, 진동 등을 흡수하여 주는 역할을 하는 방진고무로 이용되면 적합하겠다.Therefore, the rubber composition of the present invention can be used for various purposes and forms, for example, it is suitable to be used as the anti-vibration rubber that is mounted to the lower portion of the air conditioner compressor to serve to absorb the noise, vibration, etc. generated in the compressor.
