Abstract
Description
본 발명은 EPS비드를 스팀열 처리한 후 마이크로캡슐향(5/1000mm size)을 코팅처리함으로써 내구성과 내열성을 갖는 마이크로캡슐향이 톡톡 터지면서 스티로폴에서 향이 나는 것이다. 기존의 스티로폴은 EPS 비드를 가압식 또는 연속식 발포기로 스팀열을 가하여 0.2 ~0.3mm size의 조그만 비드(bead)가 60배 전후의 크기로 부피가 커진다. 이 때 발포제로는 부탄 또는 펜탄이 사용된다.The present invention is a microcapsule flavor (5 / 1000mm size) after the steam heat treatment of the EPS beads by coating the microcapsule flavor having durability and heat resistance is popping scent in Styropol. Existing Styropol is made by applying EPS heat to EPS beads using a pressurized or continuous foaming machine, so that small beads of 0.2 to 0.3mm size are about 60 times larger. In this case, butane or pentane is used as the blowing agent.
EPS의 구성은 스티렌모너머(SM)가 90% 발포제가 6~7%로 구성되어 있고 가소제, 수분함량 코팅제가 적당량 함유되어 있다.EPS is composed of styrene monomer (SM), 90% foaming agent and 6-7%, and a suitable amount of plasticizer and water content coating agent.
EPS비드를 발포기로 스팀열을 가할 때 60℃ 이상에서 발포제 즉 부탄 또는 펜탄이 빠져 나오면서 부피가 커지게 되고 대부분 110℃ 이상이면 완전 발포가 된다.When EPS heat is applied to the foaming machine, the foaming agent, ie, butane or pentane, exits at 60 ° C. or higher, and becomes bulky.
발포시간은 스팀열 처리 과정에서 가압식 발포기나 연속식 발포기의 온도에 따라 다소 차이가 있다.Foaming time is somewhat different depending on the temperature of the pressurized or continuous foamer during steam heat treatment.
EPS비드의 연화점은 90℃로 비드에 GAS가 빠져 나오면서 말랑말랑하게 되고 이 과정이 곧 발포 과정이라 할 수 있다.The softening point of EPS bead is 90 ℃ and it becomes soft as GAS comes out from the bead. This process is called foaming process.
본 발명은 EPS비드(Bead)를 발포하는 것과 그것을 다시 마이크로캡슐향으로 코팅처리 하는 것이다.The present invention is to foam the EPS beads (Bead) and to coat them back to the microcapsule flavor.
즉, EPS를 발포하고 그 발포된 EPS비드 표면에 마이크로캡슐향을 코팅처리 함으로서 내열성 기능을 가지는 마이크로 캡슐향 EPS비드가 형성되는 것이다. 이것은 크게 마이크로 캡슐향 제조과정과 EPS를 비드형태로 발포하는 과정으로 구분되며 2차 공정에서는 이들의 각각의 제조과정에서 생산된 원료를 다시 합성한다.That is, by foaming the EPS and coating the microcapsule flavor on the foamed EPS bead surface, the microcapsule flavored EPS beads having a heat resistance function are formed. This is largely divided into microcapsule manufacturing process and EPS foaming process, and in the secondary process, the raw materials produced in their respective manufacturing processes are resynthesized.
먼저 기초원료인 0.2~0.3mm size의 EPS를 110℃까지 스팀열 처리하며 발포시킨다. 발포된 EPS비드(스티로폴 형태) 표면에 그 발포된 EPS비드 부피를 0.5~5% 부피로 환산하여 5마이크로미터(㎛)크기의 캡슐향으로 코팅처리한다.First, the EPS of 0.2 ~ 0.3mm size, the basic raw material, is foamed by steam heat treatment up to 110 ℃. On the surface of the foamed EPS beads (Styropole), the volume of the foamed EPS beads is converted into a volume of 0.5-5% and coated with a capsule of 5 micrometers (㎛) size.
코팅처리된 EPS비드를 다시 60℃~80℃의 온도를 건조시킨다.The coated EPS beads are dried again at a temperature of 60 ~ 80 ℃.
1. 마이크로캡슐향의 구성1. Composition of Microcapsule Flavor
마이크로캡슐향이라 함은 일반 Oil을 마이크로 SIZE(5/1000mm)로 분해하고 이것을 수지로 감싸게 함으로써 내열성과 유용성을 수용성으로 하는 것이다. 마이크로캡슐은 주벽재와 부벽재로 나눌 수 있다.Microcapsule fragrance is to dissolve general oil into micro SIZE (5 / 1000mm) and wrap it with resin to make heat resistance and usefulness water-soluble. Microcapsules can be divided into main wall material and subwall material.
먼저 Oil향을 25%를 물70%와 함께 8,000∼10,000rpm속도로 30분정도 믹싱을 한다. 믹싱된 SIZE는 5/1000mm 정도가 되고 이것에 폴리비닐알콜(PVA 2%)를 넣고 다시 60℃온도에서 3,000rpm으로 30분정도 교반을 하면 1차 캡슐이 되는데 이것이 부벽재가 캡슐을 감싼 상태가 된다. 위의 과정을 거쳐 좀 더 단단하고 내열성을 가지게 하기 위해서 주벽재로 다시 감싸게 된다. 주벽재는 멜라민수저(3%)로 부벽재로 감싼 캡슐을 다시 멜라민수지와 합성하여 60∼70℃에서 3,000∼4,000rpm으로 30분정도 교반한 후 서서히 온도를 낮추게 되면 멜라민수지가 굳어져 단단한 고체상태의 캡슐이 된다. 이때 부벽재로 사용되는 것은 PVA대신 아라비아껌도 가능하고 주벽제로 사용되는 멜라민수지 대신 폴리우레탄이나 젤라틴과 같은 것을 사용해도 된다. 캡슐의 SIZE는 평균 5/1000mm 크기가 되고 캡슐 1EA에 구성도를 100으로 보았을 때 Oil향이 83%, 부벽재가 6.8%, 주벽재가 10.2%정도이다.First, mix 25% oil scent with 70% water for 30 minutes at 8,000 ~ 10,000rpm speed. The mixed size is about 5 / 1000mm, and polyvinyl alcohol (PVA 2%) is added to it and then stirred for 30 minutes at 3,000rpm at 60 ℃ to become the primary capsule. . Through the above process, it is wrapped with the main wall material in order to have a harder and more heat resistance. The main wall material is melamine resin (3%), and the capsules encapsulated with the sub-wall material are synthesized with melamine resin again, and stirred for 30 minutes at 3,000 to 4,000 rpm at 60 to 70 ° C. It becomes a capsule of state. At this time, as a subwall material, gum arabic may be used instead of PVA, and instead of melamine resin used as main wall, polyurethane or gelatin may be used. The average capsule size is 5 / 1000mm, and the oil composition is 83%, side wall material 6.8%, and main wall material 10.2%.
위의 %는 작업한계에 따라 다소 차이가 있을 수 있다.The above percentages may vary slightly depending on the working limits.
2. 내구성이 가미된 마이크로캡슐향 스티로폴 비드코팅 접목2. Graft Styropole Bead Coating with Durable Microcapsule
본 발명은 발포된 EPS 비드를 마이크로캡슐향 제조방법에 의해 코팅처리하는 것이다.The present invention is to coat the foamed EPS beads by a microcapsule flavor production method.
발포된 스티로폴 부피에 마이크로캡슐향을 0.5~5% 부피로 환산하여 스티로폴 주변을 다시 코팅처리한다. 이 때 마이크로캡슐향을 코팅 처리 하는 것은 교반 탱크를 이용하고 마이크로캡슐향이 코팅된 스티로폴을 다시 60℃~80℃에서 건조시키면 된다.Convert the styropol volume into 0.5 ~ 5% of the volume of the foamed styropol and coat the surrounding styropol again. At this time, coating the microcapsule flavor by using a stirring tank and drying the styropol coated with microcapsule flavor at 60 ℃ ~ 80 ℃ again.
3. 작용과정3. Process
이렇게 처리된 마이크로캡슐향 스티로폴은 단열재나 방음재, 충격흡수재 外 다수 용도에 맞게 사용을 하며 마이크로캡슐향이 톡톡 터지면서 자연상태에서는 20~30%, 움직이거나 비비면 70~80% 정도의 향이 스티로폴에서 발향된다.The treated microcapsule styropol is used for insulation, soundproofing, shock absorber and many other applications. As the microcapsule is popped, 20 ~ 30% in natural state and 70 ~ 80% scent comes out from styropol. .
본 발명은 내구성이 가미된 마이크로캡슐향 스티로폴 비드로써 단열재, 방음재, 충격흡수재로 사용할 시 은은한 향이 오래오래 지속됨으로써 스티로폴 특유의 냄새를 탈취하고 용도에 맞게 향을 사용할 수 있다.The present invention is a microcapsule-flavored styropol beads with durability added, when used as a heat insulating material, soundproofing material, shock absorber, so that the subtle scent lasts for a long time to deodorize the odor unique to Styropol and can be used according to the application.
