Description

탄소계 분말 슬러리 조성물{CHEMICAL COMPOSITION FOR CARBONACEOUS-BASED MATERIAL POWDER SLURRYN}Carbon-based powder slurry composition {CHEMICAL COMPOSITION FOR CARBONACEOUS-BASED MATERIAL POWDER SLURRYN}

본 발명은 탄소계 분말 슬러리 조성물에 관한 것으로서, 보다 상세하게는 장기간 보관이 가능한 탄소계 분말 슬러리 조성물에 관한 것이다.The present invention relates to a carbon-based powder slurry composition, and more particularly to a carbon-based powder slurry composition that can be stored for a long time.

[종래 기술][Prior art]

전자 제품, 탄소계 내화물용 도포제, 부정형 내화물, 전지 재료 등 다양한 분야에 사용되는 탄소계 물질은 일반적으로 용매와 혼합하여 슬러리를 제조하여 이를 도포하는 방식으로 사용되고 있다.Carbonaceous materials used in various fields such as electronic products, coating agents for carbon-based refractory materials, amorphous refractory materials, and battery materials are generally used by mixing with solvents to prepare slurry and coating them.

그러나 탄소계 슬러리를 제조한 후, 보관하는 공정에서 탄소질 입자가 침강되어 성분이 분리됨에 따라 장기간 보관해서 사용할 수 없이, 사용하고자 할 때마다 새로 제조하여 사용해야하는 불편이 있다.However, after preparing the carbon-based slurry, the carbonaceous particles are precipitated in the storage process, so that the components are separated, so that the components cannot be stored and used for a long time.

이러한 문제점을 방지하여, 침강을 막고 유동성을 확보하기 위해서 탄소질 입자를 미세하게 가공을 하는 방법(일본 특허 공개 제 2000-226206 호) 또는 겉보기 비중이 낮은 팽창흑연을 사용하는 방법(일본 특허 공개 제 1994-183714 호) 등을 사용하여 침강을 막음으로써 경시변화에 따른 성분 분리를 가능한 막으려는 방법이 연구되어 왔다.In order to prevent such a problem, in order to prevent sedimentation and to secure fluidity, a method of finely processing carbonaceous particles (Japanese Patent Laid-Open No. 2000-226206) or a method using expanded graphite having a low apparent specific gravity (Japanese Patent Laid-Open No. 1) 1994-183714) have been studied to prevent sedimentation by changing sedimentation over time by preventing sedimentation.

그러나 이 방법의 경우에는 평균 입도가 20 내지 30㎛의 미세 입자의 탄소계 물질을 사용하는 경우에만 가능하며, 일반적으로 시판되는 큰 입자(약 100㎛ 정도)의 탄소계 물질을 사용하는 경우에는 역시 사용할 때마다 슬러리를 제조해야하거나, 분쇄 공정을 거쳐 미세 입자를 제조해야하므로 공정이 복잡해지고 제조 비용이 추가되는 문제점이 있었다. 게다가 이러한 미세 입자를 사용하더라도 200일 이상의 장기간 보관시에는 역시 탄소계 물질의 침강이 발생되는 문제점이 있었다.However, this method is only possible when using a carbon-based material of fine particles having an average particle size of 20 to 30 μm, and generally using a commercially available carbon-based material of large particles (about 100 μm). Every time it is used, a slurry has to be prepared, or fine particles have to be prepared through a grinding process, which leads to a complicated process and additional manufacturing costs. In addition, even when such fine particles are used, there is a problem that sedimentation of the carbon-based material occurs after long-term storage for more than 200 days.

본 발명은 상술한 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 평균 입도가 약 100㎛의 커다란 입자 크기를 갖는 탄소계 분말을 사용한 장기간 보관이 가능한 탄소계 분말 슬러리 조성물을 제공하는 것이다.The present invention is to solve the above-mentioned problems, an object of the present invention is to provide a carbon-based powder slurry composition capable of long-term storage using a carbon-based powder having a large particle size of about 100 ㎛ average particle size.

상기 목적을 달성하기 위하여, 본 발명은 평균 입경 100㎛ 이하의 탄소계 분말; 계면활성제; 바인더; 및 물을 포함하는 탄소계 분말 슬러리 조성물을 제공한다.In order to achieve the above object, the present invention is a carbon-based powder having an average particle diameter of 100㎛ or less; Surfactants; bookbinder; And it provides a carbon-based powder slurry composition comprising water.

이하 본 발명을 보다 상세하게 설명한다.Hereinafter, the present invention will be described in more detail.

본 발명의 탄소계 입자 슬러리 조성물은 평균 입경 100㎛ 이하의 탄소계 분말을 포함한다. 즉, 기존에는 침강 방지를 위해서 평균 입경이 약 20 내지 30㎛인 미세 입자를 사용하였던 것에 비하여, 본 발명에서는 평균 입경이 100㎛ 부근의 커다란 입자를 갖는 것을 사용하여 200일 이상 장기간 보관한 후, 사용하여도 도포한표면의 특성이 열화하지 않는 수계 슬러리 조성물을 제조할 수 있음에 따라 입자 분쇄 공정을 실시할 필요가 없어 공정이 간단하고 경제적이다.The carbon-based particle slurry composition of the present invention contains a carbon-based powder having an average particle diameter of 100 µm or less. That is, compared with the conventional fine particles having an average particle diameter of about 20 to 30 μm to prevent sedimentation, in the present invention, after the long-term storage for 200 days or more using those having large particles having an average particle diameter of about 100 μm, Since the aqueous slurry composition which does not deteriorate the characteristic of the coated surface even if used can be manufactured, it does not need to perform a particle grinding process, and a process is simple and economical.

상기 탄소계 분말은 평균 입경이 100㎛ 이하의 분말이 바람직하다. 상기 탄소계 분말의 평균 입경이 100㎛를 초과하는 경우에는 장시간 방치할 경우 침강될 우려가 있어 바람직하지 않으나, 입경이 100㎛ 이하이기만 하면 특별한 문제점은 없다. 그러나 평균 입경이 20 내지 30㎛의 탄소계 분말을 사용하는 경우에는 입경을 감소시키기 위한 분쇄 공정을 반드시 거쳐야하므로 경제성을 고려하여 일반적으로 시판되는 70 내지 100㎛의 평균 입경을 갖는 탄소계 분말을 사용하는 적당하다.The carbon-based powder is preferably a powder having an average particle diameter of 100 µm or less. If the average particle diameter of the carbon-based powder is more than 100㎛ there is a possibility that it may settle when left for a long time is not preferable, but there is no particular problem as long as the particle diameter is 100㎛ or less. However, in the case of using a carbon-based powder having an average particle diameter of 20 to 30㎛, it is necessary to go through a grinding process to reduce the particle size, so in view of economical efficiency, a commercially available carbon-based powder having an average particle diameter of 70 to 100㎛ It is suitable to do.

상기 탄소계 분말로는 천연 인상흑연, 인조흑연 등의 결정질 탄소계 물질과 카본 블랙 등의 비정질 탄소계 물질을 사용할 수 있다.As the carbon-based powder, crystalline carbon-based materials such as natural impression graphite and artificial graphite and amorphous carbon-based materials such as carbon black may be used.

본 발명의 탄소계 분말 슬러리 조성물에서 용매로는 물을 사용할 수 있다.In the carbon-based powder slurry composition of the present invention, water may be used as the solvent.

상기 계면활성제로는 에틸렌 글리콜 또는 폴리비닐리덴 플루오라이드를 사용할 수 있으며, 이 계면활성제가 탄소계 분말의 분산을 도와주어 응집을 방지하며, 침강을 방지할 수 있으므로 평균 입도가 큰 입자를 사용하는 경우에도 장시간 보관시 침강되는 현상을 방지할 수 있다. 물론 계면활성제 사용에 따른 침강을 방지할 수 있는 입자 크기에는 한계가 있으므로, 본 발명에서는 이러한 계면활성제를 사용하여 침강을 방지할 수 있는 최적의 평균 입도를 갖는 탄소계 분말을 사용한 것이다.Ethylene glycol or polyvinylidene fluoride may be used as the surfactant, and the surfactant may help to disperse the carbon-based powder to prevent agglomeration and to prevent sedimentation. Even when stored for a long time can be prevented from settling. Of course, there is a limit to the particle size that can prevent the settling according to the use of the surfactant, the present invention uses a carbon-based powder having an optimal average particle size that can prevent the settling using such a surfactant.

상기 바인더로는 스티렌 부타디엔 러버 등의 스티렌 부타디엔계 러버면 어떠한 것도 사용할 수 있다.As the binder, any of styrene butadiene-based rubbers such as styrene butadiene rubber can be used.

본 발명의 탄소계 분말 슬러리 조성물의 제조 방법은 먼저 계면활성제와 바인더를 용매인 물에 첨가하고 교반한다. 이어서 계속 교반하면서 탄소계 분말을 첨가한다.In the method for producing a carbon-based powder slurry composition of the present invention, a surfactant and a binder are first added to water as a solvent and stirred. The carbonaceous powder is then added with continued stirring.

상기 탄소계 분말의 첨가량은 용매 100 중량부에 대하여 0 중량부 초과, 50 중량부 이하가 바람직하다. 상기 탄소계 분말의 첨가량이 50 중량부를 초과하는 경우에는, 얻어지는 조성물에 고형분의 함량이 지나치게 높아 유동성이 현저히 떨어지며, 도포성이 크게 감소하여 바람직하지 않다.The amount of the carbon-based powder added is preferably more than 0 parts by weight and 50 parts by weight or less based on 100 parts by weight of the solvent. When the added amount of the carbon-based powder exceeds 50 parts by weight, the content of solids is too high in the composition to be obtained, the fluidity is remarkably decreased, and the coating property is greatly reduced, which is not preferable.

상기 계면활성제의 첨가량은 물 100 중량부에 대하여 5 내지 20 중량부가 바람직하다. 상기 계면활성제의 첨가량이 20 중량부를 초과하는 경우에는 20 중량부면 목적하는 계면활성제의 효과를 충분히 얻을 수 있으므로, 더 과량을 사용할 필요는 없다. 또한, 상기 계면활성제의 첨가량이 5 중량부 미만인 경우에는, 계면활성제의 역할이 부족하여 평균 입경 100㎛ 이하의 입자를 사용하였을 경우에도, 수시간 만에 탄소질 입자는 침강할 수 있어 바람직하지 않다.The amount of the surfactant added is preferably 5 to 20 parts by weight based on 100 parts by weight of water. When the addition amount of the said surfactant exceeds 20 weight part, since 20 weight part can fully acquire the effect of a target surfactant, it is not necessary to use an excess amount further. In addition, when the amount of the surfactant added is less than 5 parts by weight, even when particles having an average particle diameter of 100 µm or less are used because of insufficient role of the surfactant, the carbonaceous particles may precipitate in a few hours, which is not preferable. .

상기 바인더의 첨가량은 용매 100 중량부에 대하여 10 내지 20 중량부가 바람직하다. 상기 바인더를 첨가함에 따라 도포된 조성물이 도포된 물질로부터 박리되는 것을 방지할 수 있고, 부착력을 향상시킬 수 있다.The amount of the binder added is preferably 10 to 20 parts by weight based on 100 parts by weight of the solvent. By adding the binder, it is possible to prevent the applied composition from being peeled off from the applied material, and to improve adhesion.

상기 바인더의 첨가량이 10 중량부 미만인 경우에는 부착 성능이 떨어져서, 조성물을 도포한 후, 건조시 피도포체에서 탈리(들고 일어남)되거나, 도포막에 균열이 발생하기도 하며, 20 중량부를 초과하는 경우에는 도포액의 점도가 지나치게 높아져서 도포 성능이 오히려 감소하여 바람직하지 않다.When the amount of the binder added is less than 10 parts by weight, adhesion performance is poor, and after the composition is applied, it may be detached from the coated object during drying, or cracks may occur in the coating film. The viscosity of the coating liquid becomes too high, so that the coating performance is rather reduced, which is not preferable.

이하 실시예를 통하여 본 발명을 더욱 상세히 설명한다.The present invention will be described in more detail with reference to the following examples.

[실시예 1]Example 1

물 100 중량부에 대하여 에틸렌 글리콜 20 중량부 및 스티렌 부타디엔 러버 20 중량부를 물에 첨가하고 교반하였다. 이 혼합물을 계속 교반하면서 평균 입경 100㎛의 중국산 천연 인상흑연을 물 100 중량부에 대하여 40 중량부의 양으로 첨가하고 2시간동안 교반하여 분산시켜서 흑연 슬러리를 제조하였다.20 parts by weight of ethylene glycol and 20 parts by weight of styrene butadiene rubber were added to water and stirred with respect to 100 parts by weight of water. While stirring the mixture continuously, a natural Chinese graphite having an average particle diameter of 100 µm was added in an amount of 40 parts by weight based on 100 parts by weight of water, and stirred for 2 hours to disperse to prepare a graphite slurry.

[비교예 1]Comparative Example 1

시판되는 흑연 슬러리(일본 제품, 평균 입경 5 내지 7㎛의 인상 흑연 입자 및 용매로 물 사용)를 사용하였다.A commercially available graphite slurry (made in Japan, used graphite particles with an average particle diameter of 5 to 7 µm and water as a solvent) was used.

* 도포 성능 비교* Application Performance Comparison

상기 실시예 1 및 비교예 1의 흑연 슬러리의 도포성능 비교를 위하여 일반 판유리 위에 0.5mm의 두께로 도포하여, 100℃를 유지하고 있는 건조기에서 건조한 결과, 실시예 1 및 비교예 1의 흑연 슬러리 모두 열처리에 의한 박리 현상은 관찰되지 않았다. 그러나 바늘을 이용하여 표면 스크래칭을 부여한 결과, 비교예 1의 흑연 슬러리를 도포한 경우에는 흑연 슬러리가 간단히 박리되는 것에 반해, 비교예 1에서는 박리 현상이 거의 일어나지 않았다.In order to compare the coating performance of the graphite slurry of Example 1 and Comparative Example 1, the coating was applied with a thickness of 0.5 mm on the common glass plate and dried in a drier maintained at 100 ° C. No peeling phenomenon by heat treatment was observed. However, as a result of surface scratching using a needle, when the graphite slurry of Comparative Example 1 was applied, the graphite slurry was easily peeled off, whereas in Comparative Example 1, the peeling phenomenon hardly occurred.

* 침강 거동 관찰* Sedimentation behavior observation

상기 실시예 1 및 비교예 1의 슬러리를 직경 50mm, 높이 80mm의 투명한 용기에 투입한 후, 200일을 방치한 뒤, 침강한 흑연 입자층의 두께를 관찰한 결과, 비교예 1의 흑연 슬러리의 경우에는 10㎜의 침강 흑연층을 나타낸데 비해, 실시예 1의 슬러리는 침강 흑연층이 관찰되지 않았다.After injecting the slurry of Example 1 and Comparative Example 1 into a transparent container having a diameter of 50 mm and a height of 80 mm, leaving 200 days, the thickness of the precipitated graphite particle layer was observed. Although the precipitated graphite layer of 10 mm is shown, in the slurry of Example 1, the precipitated graphite layer was not observed.

[실시예 2]Example 2

평균 입경 75㎛의 인조 흑연 분말을 사용한 것을 제외하고는 상기 실시예 1과 동일하게 실시하여 흑연 슬러리를 제조하였다. 이 슬러리를 이용하여 상기 실시예 1과 동일한 실험을 실시한 결과 동일한 성능을 관찰할 수 있었다.A graphite slurry was prepared in the same manner as in Example 1, except that artificial graphite powder having an average particle diameter of 75 μm was used. As a result of performing the same experiment as in Example 1 using this slurry, the same performance could be observed.

[비교예 2]Comparative Example 2

스티렌 부타디엔 러버의 양을 물 100 중량부에 대하여 25 중량부로 변경한 것을 제외하고는 상기 실시예 1과 동일하게 실시하여 흑연 슬러리를 제조하였다. 제조된 슬러리는 점도가 지나치게 높아 0.5mm두께의 도포가 불가능하였다.A graphite slurry was prepared in the same manner as in Example 1 except that the amount of styrene butadiene rubber was changed to 25 parts by weight based on 100 parts by weight of water. The slurry prepared was too high to apply a 0.5 mm thickness.

본 발명에 의해 제조한 탄소계 분말 분산 슬러리는 평균입경 100㎛ 부근의 비교적 커다란 탄소질 분말을 사용하여 장시간의 방치 후에도 침강이 일어나지 않는 슬러리로서, 전자제품에 사용되는 흑연 도포제에서부터 탄소계 내화물용 도포제 및 부정형 내화물로의 사용도 가능할 것이다.The carbon-based powder dispersion slurry prepared according to the present invention is a slurry which does not settle even after being left for a long time using a relatively large carbonaceous powder having an average particle diameter of about 100 μm, and is a graphite coating agent used in electronic products and a coating agent for carbon-based refractory materials. And use as amorphous refractory.
