준불연 발포 스티로폼 제조용 준불연 비드 조성물 및 이의 제조방법Semi-non-flammable bead composition for producing semi-non-flammable foamed styrofoam and preparation method thereof
본 발명은 준불연급의 발포 스티로폼을 제조하기 위한 비드 조성물과 이를 제조하는 방법에 관한 것이다.The present invention relates to a bead composition for producing semi-disparate foamed styrofoam and a method of making the same.
일반적으로 발포스티로폼(Expanded Polystyrene)은 단열성과 완충성 및 가공성이 우수하므로 산업 전반에 걸쳐 널리 사용되고 있으며 특히 제품을 보호하는 포장재나 건축용 단열재 및 흡음재로서 주로 사용되고 있다.In general, expanded polystyrene is widely used throughout the industry because of its excellent thermal insulation, buffering properties, and processability, and is particularly used as a packaging material for protecting products, insulation for building, and sound absorption material.
하지만 상기 스티로폼은 열에 매우 취약하므로 화재시 열에 의해 스티로폼이 연소되어 화재의 확산을 초래하고 인체에 유해한 유독가스를 발생 시킴으로서 인명피해를 유발시키는 문제점이 있었다.However, since the styrofoam is very vulnerable to heat, the styrofoam is burned by the heat during the fire, causing the spread of the fire and causing toxic gases harmful to the human body.

Accordingly, Patent No. 10-0825203 discloses that a foamed styrofoam prepared by injecting a flame-retardant composition having self-extinguishing property into particles of foamed styrofoam is prepared to have a flame-retardant grade 3 flame-retardant foamed styrofoam. A composition for preparing a flame retardant foamed styrofoam and a method for preparing a flame retardant foamed styrofoam raw material using the same, and a variety of techniques for manufacturing a flame retardant foamed styrofoam have been presented.

제1단계 : 스티로폼원료(노비드) 표면을 1차 조성액으로 코팅 First step : coating the surface of styrofoam raw material (novid) with the first composition
스티로폼원료 600 중량부를 교반기에 투입하고 1차 조성액 13.8 ~ 46.8 중량부를 분사하여 500 ~ 750 RPM으로 2 ~ 4 분간 교반한다.600 parts by weight of styrofoam raw material is added to the stirrer, and 13.8 to 46.8 parts by weight of the first composition is sprayed and stirred at 500 to 750 RPM for 2 to 4 minutes.
본 단계는 노비드의 표면을 녹이기 위한 것으로서, 상기 1차 조성액은 톨루엔 5.0 ~ 17.0 중량부, 메틸렌클로라이드 0.3 ~ 0.9 중량부, 우레탄수지 1.0 ~ 3.4 중량부, 카바이드용액(탄소를 포함하는 용액) 1.5 ~ 5.1 중량부, 염화파라핀 1.0 ~ 3.4 중량부, 에탄올 또는 메탄올 5.0 ~ 17.0 중량부로 구성되며, 노비드는 발포되기 전의 스티로폼 원료를 의미한다. 상기 메틸렌클로라이드는 MEK(methyl ethyl ketone)으로 대체할 수도 있으며, 이를 희석하기 위하여 물 대신 에탄올 또는 메탄올을 사용한다. 물을 사용하지 않음으로서 별도의 건조시간을 필요로 하지 않게 되어 작업성이 향상된다.This step is to dissolve the surface of the bead, the primary composition is 5.0 to 17.0 parts by weight of toluene, 0.3 to 0.9 parts by weight of methylene chloride, 1.0 to 3.4 parts by weight of urethane resin, carbide solution (solution containing carbon) 1.5 ~ It is composed of 5.1 parts by weight, 1.0 to 3.4 parts by weight of paraffin chloride, 5.0 to 17.0 parts by weight of ethanol or methanol, and novid means styrofoam raw material before foaming. The methylene chloride may be replaced with methyl ethyl ketone (MEK), and ethanol or methanol is used instead of water to dilute the methylene chloride. By not using water, a separate drying time is not required and workability is improved.
2단계 : 제1단계의 조성물의 표면에 흑연혼합물을 부착 Step 2 : attaching the graphite mixture to the surface of the composition of the first step
교반기에 흑연혼합물 2.0 ~ 6.8 중량부를 투입하여 500~750 RPM으로 4 ~ 6 분간 교반한다.2.0 to 6.8 parts by weight of the graphite mixture is added to the stirrer and stirred at 500 to 750 RPM for 4 to 6 minutes.
본 단계에서는 제1단계에서 표면이 녹은 노비드에 흑연혼합물이 부착되는데, 상기 흑연혼합물은 팽창흑연 1.0 ~ 3.4 중량부, 인상흑연 1.0 ~ 3.4 중량부로 구성되며 분말(powder)형태의 것을 사용한다.In this step, the graphite mixture is attached to the surface of the bead melted in the first step, the graphite mixture is composed of 1.0 ~ 3.4 parts by weight of expanded graphite, 1.0 ~ 3.4 parts by weight of graphite graphite and use a powder form.
팽창흑연은 난연성을 높여주어 불이 옮겨붙는 것을 방지하는 역할을 하고, 인상흑연은 단열성이 뛰어나므로 불에 노출되더라도 온도가 발화점까지 올라가지 않도록 하는 역할을 한다. 이를 고루 혼합하여 노비드에 부착함으로써 준불연급의 조성물을 제조할 수 있게 되는 것이다.Expanded graphite increases the flame retardancy to prevent the fire from being transferred, and impression graphite has excellent thermal insulation, so that the temperature does not rise to the ignition point even when exposed to fire. By mixing it evenly and attaching to the bead will be able to produce a semi-disparate composition.
제3단계 : 제2단계의 조성물 표면을 2차 조성액으로 코팅 Third step : coating the surface of the composition of the second step with a secondary composition liquid
교반기에 2차 조성액 15.0 ~ 51.0 중량부를 분사하여 250 ~ 400 RPM으로 4 ~ 6 분간 교반한다.15.0-51.0 parts by weight of the secondary composition solution is sprayed on the stirrer and stirred at 250-400 RPM for 4-6 minutes.
본 단계에서 흑연혼합물이 부착된 제2단계 조성물의 표면이 2차 조성액에 의해 코팅되는데, 상기 2차 조성액은 톨루엔 5.0 ~ 17.0 중량부, 인상흑연 1.5 ~ 5.1 중량부, 우레탄수지 1.0 ~ 3.4 중량부, 카바이트용액 1.5 ~ 5.1 중량부, 염화파라핀 1.0 ~ 3.4 중량부, 에탄올 또는 메탄올 5.0 ~ 17.0 중량부로 구성된다.In this step, the surface of the second stage composition to which the graphite mixture is attached is coated by the secondary composition liquid, which is 5.0 to 17.0 parts by weight of toluene, 1.5 to 5.1 parts by weight of graphite graphite, and 1.0 to 3.4 parts by weight of urethane resin. It consists of 1.5 to 5.1 parts by weight of a carboxyl solution, 1.0 to 3.4 parts by weight of paraffin chloride, and 5.0 to 17.0 parts by weight of ethanol or methanol.
1차 조성액과 대부분 동일하나, 메틸렌클로라이드 대신 인상흑연이 사용되는 것이 차이점이다. 따라서 메틸렌클로라이드에 의해 노비드의 표면을 녹이는 제1단계는 표면을 골고루 얇게 녹이기 위해 빠른 회전수로 짧게 교반하고, 메틸렌클로라이드가 들어가지 않는 제3단계에서는 낮은 회전수로 보다 긴 시간동안 교반하여 2차 조성액에 의한 코팅막이 골고루 두껍게 형성되도록 한다. 즉, 단열성이 높은 인상흑연으로 단열막을 형성하여 불에 의한 열이 내부로 전달되지 않도록 차단하는 것이다. 팽창흑연과 혼합하여 사용하는 것 보다 인상흑연만 사용하여 단열막을 두껍게 형성하는 것이 스티로폼원료로 열이 직접전달되는 것을 막을 수 있어 열에 의한 형태변화와 그을음을 최소화 할 수 있다.Most of them are the same as the primary composition, except that impression graphite is used instead of methylene chloride. Therefore, the first step of dissolving the surface of the nodide by methylene chloride is briefly stirred at high speed to dissolve the surface evenly and thinly, and in the third step without methylene chloride, the second step is stirred at a lower speed for a longer time. The coating film by the composition is evenly formed to be thick. That is, by forming a heat insulating film of the impression graphite with high heat insulating property to block the heat by the fire is not transferred to the inside. Forming a thick insulating film using only impression graphite, rather than mixing with expanded graphite, can prevent direct transfer of heat to the styrofoam material, thereby minimizing the shape change and soot caused by heat.
제4단계 : 제3단계의 교반기 내 혼합물을 4 ~ 6 분간 건조 Step 4 : Dry the mixture in the stirrer of Step 3 for 4 to 6 minutes
교반을 멈추고 상온에서 자연건조시킨다.Stop stirring and dry naturally at room temperature.
제5단계 : 제4단계의 혼합물을 발포 5th step : foaming the mixture of the 4th step
제4단계까지 거쳐 건조된 조성물을 계근하여 발포기로 이송시킨 뒤 이를 발포시켜 비드를 만들게 된다.After the fourth step, the dried composition is weighed and transferred to a foamer, and then foamed to make beads.
