Description

고점도 잉크 분산 유화 시스템High viscosity ink dispersion emulsification system
본 발명은 고점도 잉크 분산 유화 시스템에 관한 것으로, 보다 상세하게는 고점도 잉크 분산과 미세 파우더 입자를 안전하게 혼합하기 위한 고점도 잉크 분산 유화 시스템에 관한 것이다.The present invention relates to a high viscosity ink dispersion emulsification system, and more specifically, to a high viscosity ink dispersion emulsification system for safely mixing high viscosity ink dispersion and fine powder particles.
최근에 잉크나 이차전지 활물질 등 기초 소재 산업 분야에서는 입자의 분산과 유화 등, 세밀성과 균질성이 완제품의 품질에 영향을 미치는 중요한 핵심 공정으로 여겨지고 있다.Recently, in the basic materials industry, such as ink and secondary battery active materials, fineness and homogeneity, such as particle dispersion and emulsification, are considered important core processes that affect the quality of finished products.
특히, 4차산업의 중요한 분야인 잉크젯 프린팅과 3D프린팅 기술과 이에 소요되는 정밀 잉크 제조의 산업은 매우 중요한 기초 소재산업으로 인식되고 있다. In particular, inkjet printing and 3D printing technology, which are important areas of the 4th industrial revolution, and the precision ink manufacturing industry required for them are recognized as very important basic material industries.
잉크를 만드는 대표적 소재로 바니시(Varnish)와 안료(Pigment) 소재가 있는데, 소재바니시(Varnish)란, 광택이 있는 투명한 피막을 형성하는 도료로써, 천연수지나 합성수지를 용매에 녹여 만들며 가구나 선박, 차, 나무 따위에 바르면 용매가 휘발되면서 표면에 막이 생겨 광택을 내며, 습기를 방지하는 역할을 한다. 또한 안료(Pigment)란, 동물 혹은 식물 등에 자연 상태로 존재하는 색소로써 통상 안료 입자, 또는 물감 재료로 불리며, 기본적으로 미세입자의 분말 형태로 이루어져 있다.Representative materials for making ink include varnish and pigment. Varnish is a paint that forms a glossy transparent film. It is made by dissolving natural resin or synthetic resin in a solvent and is used for furniture, ships, and cars. When applied to a surface such as wood, the solvent volatilizes and a film is formed on the surface, making it shiny and preventing moisture. In addition, pigment is a pigment that exists in nature in animals or plants, and is usually called pigment particles or paint materials, and is basically in the form of a powder of fine particles.
바니시와 안료 혼합, 잉크 제조의 공정 순서를 살펴보면, 먼저 하드레진을 용매에 녹여 바니시(Varnish)를 제조하고, 이 바니시에 분말 상태인 안료(Pigment)를 투입하여 가열 숙성을 거쳐 제조하게 되는데, 이때 바니시는 고점도 이어서 여기에 분말상태인 안료를 균질하게 섞는 문제는 매우 어려운 공정지만 고품질 잉크를 제조하는데 매우 중요한 바로메터 기술로 여겨지고 있다.Looking at the process sequence of mixing varnish and pigment and manufacturing ink, first, hard resin is dissolved in a solvent to produce varnish, and then powdered pigment is added to this varnish and heated and aged. Varnish has a high viscosity, so mixing powdered pigments homogeneously is a very difficult process, but it is considered a very important barometer technology in producing high-quality ink.
고품질 잉크를 제조하는 데 있어서 세밀화, 균질화를 가능하게 해주는 기술로“분쇄”“분산”“유화”“균질화”등 이 있는데, 고체가 액체에 또는 액체가 액체에 균일하게 퍼져 안정된 상태로 존재하는 것으로, 대상에 따라 고체를 액체에 분산시키는“분산(dispersion)”과 계면이 존재하는 액체와 액체를 섞이게 만드는“유화(emulsion)”로 구분되고, 분쇄(Grinding)란 입자의 크기를 작게 만드는 것을 의미하게 되는데, 입자의 크기를 작게 만든다는 것은 강한 에너지를 물질에 가함으로써 가능하게 된다. 또한 균질화(Homogenization)불균질한 혼합물의 각 성분을 미세한 입자상 혹은 분자상으로까지 분산시켜 전체를 균질하게 하는 것을 말한다.Technologies that enable refinement and homogenization in the production of high-quality ink include “grinding,” “dispersing,” “emulsification,” and “homogenization,” which exist in a stable state by uniformly spreading a solid into a liquid or a liquid into a liquid. Depending on the object, it is divided into “dispersion”, which disperses a solid into a liquid, and “emulsion”, which mixes the liquid with the liquid at the interface. Grinding refers to reducing the size of particles. Reducing the size of particles is possible by applying strong energy to the material. Homogenization also refers to dispersing each component of a heterogeneous mixture into fine particles or molecules to make the whole homogeneous.
원재료의 분산 기술로 대한민국 공개특허번호10-2010-0087905 호 "이중분리구조를 갖는 분산분쇄기"에는 여과임펠러와 회전로터를 각각 개별 구동 및 회전속도를 개별 제어하므로 가공원료가 분쇄 분산되는 본체 내부의 상하 측에 형성되는 회전압력차를 제공할 수 있어 가공원료의 분산분쇄에 따른 효율을 높일 수 있고 분쇄용 볼의 크기를 아주 작게 하더라도 양질의 미립자로 분쇄 분산시켜 분리 배출할 수 있도록 하였으나, 분산작업 효율이 떨어지고 시간이 많이 소요되는 단점이 있다.With the dispersion technology for raw materials, Korean Patent Publication No. 10-2010-0087905, “Dispersion Grinder with Double Separation Structure,” operates the filtering impeller and the rotary rotor individually and controls the rotation speed individually, so that the processed raw materials are pulverized and dispersed inside the main body. By providing a rotational pressure difference formed on the upper and lower sides, the efficiency of dispersion and grinding of processed raw materials can be increased. Even if the size of the grinding balls is very small, it is possible to crush and disperse them into high-quality fine particles and separate them for discharge. It has the disadvantage of being inefficient and taking a lot of time.
또한, 이러한 문제점을 해결하기 위하여, 대한민국 공개특허 제 10-2014-0073023호 "원 패스 타입 분산유화장치"에는 분산유화장치의 챔버 내부에서 회전 가능하도록 설치된 샤프트에 고정 전단 돌기가 구비된 스테이터와 회전 전단 돌기가 구비된 로터를 복수의 층으로 결합하여 회전 전단 돌기가 회전하지 않는 고정 전단돌기와 상대적으로 샤프트의 회전에 의해 회전하면서 투입된 분산유화대상물에 전단력을 가함으로써, 분산유화대상물에 대한 분산유화의 효율이 우수하도록 하고 유동성이 낮은 고점도의 분산유화대상물도 분산 유화 처리할 수 있도록 구성되어 있어, 연속적인 분산 유화 작업과 동시에 바로 이송하여 코팅 및 관련 작업에 활용할 수 있는 장점이 있다.In addition, in order to solve this problem, Korean Patent Publication No. 10-2014-0073023, “One Pass Type Dispersion Emulsification Device,” includes a stator equipped with a fixed shear protrusion on a shaft rotatably installed inside the chamber of the dispersion emulsification device and a rotating stator. A rotor equipped with shear protrusions is combined into a plurality of layers, and the rotating shear protrusions rotate relative to the fixed shear protrusions that do not rotate by the rotation of the shaft, thereby applying a shearing force to the inserted dispersed emulsification object. It has excellent efficiency and is designed to handle even high-viscosity dispersion emulsification objects with low fluidity, so it has the advantage of being able to be used for coating and related work by immediately transferring it at the same time as continuous dispersion emulsification work.
한편, 용액에 화학활성을 갖는 각종 파우더를 투입하고 분산하는 공정은 매우 어렵고, 특히 미세 나노파우터의 경우는 흡입시 더욱 큰 위생문제를 야기하고 있어 이를 개선할 필요성이 대두되고 있다. Meanwhile, the process of adding and dispersing various powders with chemical activity in a solution is very difficult, and in particular, fine nano powders cause greater hygiene problems when inhaled, so there is a need to improve this.
이에 본 발명자는 잉크 제조과정에서 용액에 파우더를 쏟아붓고 교반하는 과정 대신에 분산유화장치에서 미세 분말을 흡입하여 액체 분산용매에 섞어 분산유화시키면 분말의 비산을 막을 수 있어 작업자의 위생상 위험을 방지하고 주변의 오염을 막을 수 있음을 발견하고 본 발명을 완성하였다.Therefore, instead of pouring powder into a solution and stirring it during the ink manufacturing process, the present inventor suctioned fine powder from a dispersion emulsification device and mixed it with a liquid dispersion solvent to disperse and emulsify it, thereby preventing scattering of the powder and preventing sanitary hazards for workers. and discovered that it could prevent surrounding pollution, and completed the present invention.

도 1과 도 2를 참조하면, 본 발명 실시예에 따른 고점도 잉크 유화 분산 시스템(1)은, 파우더 흡입형 혼합분산 시스템(10)과: 챔버형 다단 분산유화 임펠러 시스템(20);을 순차적으로 통과시켜 3단 롤밀(30)로 보내는 고점도 잉크 분산 시스템을 제공한다.Referring to Figures 1 and 2, the high-viscosity ink emulsification dispersion system 1 according to an embodiment of the present invention sequentially includes a powder suction type mixing and dispersion system 10 and a chamber-type multi-stage dispersion emulsification impeller system 20. It provides a high-viscosity ink dispersion system that passes through and sends it to the three-stage roll mill (30).
도 3 내지 도 5를 참조하면, 본 발명에 따른 파우더 흡입형 혼합 분산 시스템(10)은 파우더 혼합 탱크(11): 도료분말 용기(12) : 파우더 흡입 분산유화기(13)로 구성된다.Referring to Figures 3 to 5, the powder suction type mixing and dispersion system 10 according to the present invention is composed of a powder mixing tank 11, a paint powder container 12, and a powder suction dispersion emulsifier 13.
이때 파우더 흡입 분산유화기(13)상에서 나노 파우더를 흡입하는 흡입 로터가 앞뒤로 위치하여, 고속 회전하면서 분산함과 동시에 흡입력을 발생시킨다.At this time, the suction rotor that sucks the nano powder is positioned back and forth on the powder suction dispersion emulsifier 13, and rotates at high speed to disperse it and generate suction force at the same time.
파우더 흡입형 혼합 분산 시스템(10)은 잉크분산 용매인 바니시 제조를 위한 탱크(11)와 도료분말 용기(12)와 이를 흡입하여 혼합분산을 시행하는 파우더 흡입 분산유화기(13)와 1차 분산 유화된 혼합물을 챔버형 다단 분산 임펠러(20)로 흘려보내되, 펌프(14)를 통해 챔버형 다단 분산유화 임펠러(21)로 흘려보낸다.The powder suction type mixing and dispersion system (10) includes a tank (11) for manufacturing varnish, which is an ink dispersion solvent, a paint powder container (12), a powder suction dispersion emulsifier (13) that inhales the mixture and dispersion, and primary dispersion. The emulsified mixture flows to the chamber-type multi-stage dispersion impeller (20) and flows to the chamber-type multi-stage dispersion emulsification impeller (21) through the pump (14).
또한, 본 발명은, 펌프(14)를 통해 챔버형 다단 분산유화 임펠러(21)로 흘려보내기 전에 파우더 흡입 분산유화기(13)에서 1차 분산 유화된 혼합물을 탱크(11)로 보내어 일정한 수준으로 분산 및 균질화 될 때까지 반복해서 순환 실시할 수 있다.In addition, the present invention sends the primary dispersion and emulsification mixture from the powder suction dispersion emulsifier (13) to the tank (11) before flowing it to the chamber-type multi-stage dispersion emulsification impeller (21) through the pump (14) to maintain a constant level. The cycle can be repeated repeatedly until dispersed and homogenized.
도 6과 도 7을 참조하면, 챔버형 다단 분산유화 임펠러시스템(20)은 파우더 흡입형 혼합분산 시스템(10)에서 분산 유화된 혼합물을 챔버형 다단 분산유화 임펠러(21)로 흘려보내는 펌프(14)를 더 구비한다. Referring to Figures 6 and 7, the chamber-type multi-stage dispersion emulsification impeller system (20) is a pump (14) that flows the dispersed and emulsified mixture from the powder suction-type mixing and dispersion system (10) to the chamber-type multi-stage dispersion emulsification impeller (21). ) is further provided.
이때 액체 상태의 잉크분산 용매인 바니시 제조를 위한 탱크(11)와 도료분말 용기(12)와 이를 흡입하여 혼합분산을 시행하는 파우더 흡입 분산유화기(13)와 1차 분산 유화된 혼합물을 챔버형 다단 분산 임펠러(20)로 흘려보내되, 펌프(14)를 통해 챔버형 다단 분산유화 임펠러(21)로 흘려보냄으로써 유체를 강제로 쳄버안에서 이동시키고 다단임펠러는 상단의 강력한 모터로 회전시켜 전단력과 분산유화에 전담토록 하는 효과를 갖도록 한다. At this time, a tank (11) for manufacturing varnish, which is a liquid ink dispersion solvent, a paint powder container (12), a powder suction dispersion emulsifier (13) for mixing and dispersing the liquid ink, and a chamber-type dispersion emulsifier for the primary dispersion and emulsification mixture. It flows to the multi-stage dispersion impeller (20), and flows to the chamber-type multi-stage dispersion emulsification impeller (21) through the pump (14), forcing the fluid to move within the chamber, and the multi-stage impeller is rotated by a powerful motor at the top to generate shear force and It should have the effect of being dedicated to dispersed emulsification.
이때 챔버형 다단 분산유화 임펠러(21)는 상하 3~7단의 단위 로터와 스테이트로 구성된 임펠러들(22)로 적층되고 임펠러들의 로터와 스테이터 간극이 0.2mm 이하로 구성하여 파우더 흡입형 혼합분산 시스템(10)에서 분산 유화된 혼합물을 펌프(14)를 이용하여 강제로 순환시키며 쳄버안의 임펠러들의 로터와 스테이터 간극을 통과하면서 강한 운동에너지를 받아 입자들이 보다 미세하게 분쇄되며 아울러 2차의 분산과 유화를 수행하게 된다. At this time, the chamber-type multi-stage dispersion emulsification impeller 21 is stacked with impellers 22 composed of unit rotors and states of 3 to 7 stages upper and lower, and the gap between the rotor and stator of the impellers is 0.2 mm or less to form a powder suction type mixing and dispersion system. In (10), the dispersed and emulsified mixture is forcibly circulated using the pump (14), and as it passes through the gap between the rotor and stator of the impellers in the chamber, the particles are pulverized more finely by receiving strong kinetic energy, and secondary dispersion and emulsification occur. will be performed.
본 발명은 고점도 분산에 특화되도록 0.2mm 이하 간극으로 임펠러(로터, 스테이터)를 강한 회전력을 가진 모터에 의해 회전하는 회전자는 회전속도가 증가할수록 순간적으로 고속의 회전 전단력을 가지게 되며, 임펠러의 간격 즉, 회전자와 고정자의 간극이라는 매우 미세한 공간을 분산 대상물이 강한 회전속도로 통과할 때 높은 전단 효과가 발생해 입자의 크기가 순간적으로 매우 미세하게 분산하게 되며, 이를 위해 간극을 최소화한다.The present invention specializes in high-viscosity dispersion, and the impeller (rotor, stator) is rotated by a motor with strong rotational force with a gap of 0.2 mm or less. The rotor instantaneously has a high-speed rotational shear force as the rotation speed increases, and the gap between the impellers, that is, , When the dispersed object passes through the very fine space called the gap between the rotor and the stator at a high rotational speed, a high shear effect occurs, and the size of the particles is instantly and very finely dispersed. To this end, the gap is minimized.
미도시되어 있지만 2차의 분산과 유화를 거친 분산물을 순환적으로 일정한 수준의 분산유화가 이루어 질때까지 챔버형 다단 분산유화 임펠러시스템(20)을 반복해서 실시할 수 있다.Although not shown, the chamber-type multi-stage dispersion emulsification impeller system 20 can be repeatedly performed on the dispersion that has undergone secondary dispersion and emulsification until a certain level of dispersion and emulsification is achieved.
챔버형 다단 분산유화 임펠러(21)는 이중 자켓으로 둘러싸 냉수를 통과시켜 온도를 낮추거나 조절할 수 있도록 하고 있는데, 실제로 챔버형 다단 분산유화 임펠러(21)안에서 상하로 적층되어 쳄버를 형성하고 외벽은 스테이터가 되고 내부 회전자들은 로터가 되어 상부에 설치된 모터에 의해 분당 3000~7000회 회전하게 되므로 쳄버안에서 로터-스테이터의 사이로 펌프(14) 압력으로 상승하면서 큰 에너지가 발생하여 분산물이 타거나 변질될 우려가 있어 이중 자켓으로 둘러 싸 냉수를 통과시켜 온도를 낮추거나 조절할 수 있도록 한다. 이경우 유체가 지속적으로 흐르는 상태이고 냉각수 자켓의 설치로 100 ℃ 이하로 처리도 가능하다.The chamber-type multi-stage dispersion emulsification impeller (21) is surrounded by a double jacket to allow cold water to pass through to lower or control the temperature. In fact, it is stacked up and down within the chamber-type multi-stage dispersion emulsification impeller (21) to form a chamber, and the outer wall is a stator. Since the internal rotors become rotors and rotate 3000 to 7000 times per minute by the motor installed at the top, large energy is generated as the pressure of the pump 14 rises between the rotor and stator in the chamber, causing the dispersion to burn or deteriorate. Due to concerns, it is surrounded by a double jacket and passes cold water to lower or control the temperature. In this case, the fluid flows continuously and it is possible to process temperatures below 100°C by installing a coolant jacket.
본 발명의 시스템을 활용하여 분산하고자 하는 소재인 바니시와 안료 혼합, 분산물은 최종 입도가 10미크론 이하, 점도 약 200,000cps 의 물질로써 시간당 500kg 이상의 양을 생산이 가능하다. 기존의 공정시간은 최소 20시간에서 최대 40시간까지 소요되었으나, 본 발명은 기존 기술을 개선하여 파우더 흡입형 유화·분산 시스템(10)을 도입하고 공정을 축소함과 동시에 원패스로 처리 가능한 챔버형 다단 분산 임펠러(21)을 통과시켜 시간을 대폭 단축하여 소요 시간도 1사이클당 최대 10시간 미만으로 대폭 축소할 수 있다. The varnish and pigment mixture and dispersion, which are the materials to be dispersed using the system of the present invention, have a final particle size of 10 microns or less and a viscosity of about 200,000 cps, and can be produced in quantities of more than 500 kg per hour. The existing process time took from a minimum of 20 hours to a maximum of 40 hours, but the present invention improved the existing technology by introducing a powder suction-type emulsification and dispersion system (10) and reducing the process while simultaneously providing a chamber type that can be processed in one pass. By passing through the multi-stage dispersion impeller 21, the time can be greatly shortened to a maximum of less than 10 hours per cycle.
