고기능성 합성섬유 첨가용 세라믹 미분체의 제조방법 및 그 합성섬유의 제조방법{Method for manufacturing ceramic pulverulent to be added for manufacturing synthetic fiber of high functional}Method for manufacturing ceramic fine powder for high functional synthetic fiber and method for manufacturing synthetic fiber thereof {Method for manufacturing ceramic pulverulent to be added for manufacturing synthetic fiber of high functional}

본 발명은 기능성 합성섬유의 첨가제로 사용되는 세라믹 미분체의 제조방법과 이를 이용한 합성섬유의 제조방법에 관한 것으로서 보다 상세하게는 천연광물 및 세라믹을 소성하지 않고, 분산제와 함께 슬러리를 제조하여 제조된 슬러리를 분쇄매체가 조정된 2단계 분쇄를 통하여 1.0㎛이하의 미분쇄된 세라믹이 80%이상 함유된 슬러리를 제조하고 이를 원심분리에 의한 분급을 통하여 1.0㎛이하의 미분체를 제조한후 이를 건식 혹은 습식으로 폴리머에 혼합하여 세라믹 합성수지를 만들고 이를 용융방사를 통해 15㎛이하(모노 0.3∼4데니르)의 극세 합성섬유를 제조하는 방법에 관한 것이다.The present invention relates to a method for preparing ceramic fine powder used as an additive of a functional synthetic fiber and a method for preparing a synthetic fiber using the same, and more particularly, to prepare a slurry with a dispersant without firing natural minerals and ceramics. Slurry was prepared into a slurry containing 80% or more of pulverized ceramics of 1.0 μm or less through two-stage grinding with adjusted grinding media, and then fine powders of 1.0 μm or less through classification by centrifugation. Alternatively, the present invention relates to a method of manufacturing a ceramic synthetic resin by wet mixing with a polymer to produce ultrafine synthetic fibers of 15 μm or less (mono 0.3 to 4 denier) through melt spinning.

일반적으로 합성섬유는 축중합 반응에 의해 제조된 칩(Resin chip)을 용융 방사하여 제조한다. 그리고 합성섬유의 물리화학적 특성을 향상시키기 위하여 산화티타늄, 맥반석, 운모 등의 세라믹 미분체를 분말상태로 첨가하고 있다. 대한민국 특허 등록 10-231060호 "운모석을 함유한 원사 및 그 제조방법"에서는 운모를 1200℃에서 소성하여 4,000에서 12,500메쉬로 분쇄하여 얻어진 분말을 혼합하여 폴리에스테르계 합성섬유를 제조하고 있다.In general, synthetic fibers are produced by melt spinning a chip (Resin chip) produced by the polycondensation reaction. In order to improve the physicochemical properties of synthetic fibers, ceramic fine powders such as titanium oxide, elvan, and mica are added in powder form. Republic of Korea Patent Registration No. 10-231060 "The yarn containing mica stone and its manufacturing method" is a polyester-based synthetic fiber is prepared by mixing the powder obtained by firing the mica at 1200 ℃ and pulverized from 4,000 to 12,500 mesh.

상기와 같은 종래의 합성섬유 제조방법에 있어서와 같이 소성하여 세라믹 미분체를 제조하면 운모 등과 같은 저온 변형 세라믹은 결정상 변이가 일어나 그 특유의 물성이 없어지며, 분쇄에 있어서 시간과 에너지가 필요한 단점이 있으며 그리고 1.0㎛이상의 미분체를 사용하면 15㎛이하의 극세사 장섬유를 제조할수 없는 어려움이 발생한다. 그리고 분쇄시 분쇄매체를 조정하지 않고 분쇄를 하면 1.0㎛이하의 미분체 제조가 어려우며, 미분체의 분산 역시 어려워 응집을 막는 재분산 공정이 필요하여 섬유 제조비용이 상승하는 문제점이 수반된다. 또한 상기와 같은 종래의 방법으로는 스핀드로 방식에 어려움이 있으며 원사의 2차가공시 사도 등의 마모가 많이 일어나는 등의 제반비용이 많이 소모되는 경제적 손실이 있다.When the ceramic fine powder is produced by firing as in the conventional synthetic fiber manufacturing method as described above, low-temperature deformed ceramics such as mica cause crystal phase transformation, so that their specific properties are lost, and the disadvantage of requiring time and energy in grinding And when the fine powder of more than 1.0㎛ is used, it is difficult to produce microfiber filament of less than 15㎛. And when grinding without adjusting the grinding media during the grinding, it is difficult to manufacture the fine powder of 1.0㎛ or less, difficult to disperse the fine powder is required to re-dispersion process to prevent the cohesion is accompanied with the problem that the fiber manufacturing cost increases. In addition, the conventional method as described above has a difficulty in the spin draw method, there is an economic loss that consumes a lot of costs, such as a lot of wear, such as yarn during the secondary processing of the yarn.

본 발명은 상기와 같은 종래방법의 문제점을 개선하여 1.0㎛이하의 세라믹 미분체를 제조하고 이를 폴리머와 혼합하여 세라믹 합성수지(Resin chip)를 만들고 이를 용융 방사하여 천연광물 및 세라믹 미분체가 가지는 물성을 나타내는 기능성 합성섬유를 량산화할수 있는 방법을 제공하는 것이다.The present invention is to improve the problems of the conventional method as described above to prepare a ceramic fine powder of less than 1.0㎛ and mix it with a polymer to make a ceramic resin (Resin chip) and melt spinning to represent the physical properties of natural minerals and ceramic fine powder It is to provide a method for mass oxidizing functional synthetic fibers.

상기의 목적을 달성하기 위하여 본 발명에서는 천연광물 및 세라믹을 소성하지 않고 알콜에 분산시켜 점도 10 내지 1,000샌티포아즈 범위의 천연광물 및 세라믹분말 함량 30 내지 90 중량%의 알콜 슬러리를 제조하는 단계, 상기 세라믹 슬러리를 2.0에서 10.0mm의 분쇄매체가 혼합된 분쇄기에서 2단계 분쇄하는 단계, 상기 단계에서 얻어진 1.0㎛(12,500메쉬)이하의 분말이 함유된 슬러리를 원심분리를 이용한 분급으로 완전한 1.0㎛이하의 분말이 함유된 슬러리를 제조하는 단계, 상기 단계에서 얻어진 슬러리를 분무건조하여 건식 미분체를 제조하는 단계, 상기 단계에서 얻어진 과립을 제트밀에서 완전한 분말을 제조하는 단계로 미분이 가능하고 상기 단계에서 얻어진 세라믹 미분체를 합성수지에 혼합하여 세라믹 합성수지를 만들고 이를 용융방사하는 단계로 이루어진다.In order to achieve the above object, in the present invention, by dispersing natural minerals and ceramics in alcohol without firing, preparing an alcohol slurry having a natural mineral and ceramic powder content of 30 to 90% by weight in the range of viscosity 10 to 1,000 Santipoise, The ceramic slurry was pulverized in two stages in a pulverizer in which 2.0 to 10.0 mm pulverization media were mixed, and the slurry containing the powder of 1.0 탆 (12,500 mesh) or less obtained in the above-described step was centrifuged and classified to 1.0 탆 or less. Preparing a slurry containing the powder of the powder, spray drying the slurry obtained in the above step to prepare a dry fine powder, and preparing the fine powder in the jet mill by granulating the granules obtained in the step. The ceramic fine powder obtained in the above step is mixed with synthetic resin to make ceramic synthetic resin and melt spinning Is done.

도 1은 본 발명에 따라 합성섬유 첨가용 세라믹 미분체를 제조하기 위한 장치를 보여주는 예시도로서, 알콜에 천연광물 및 세라믹을 소성하지 않고 분산시키며, 이를 2단계 분쇄하여 세라믹 미분체가 함유된 슬러리의 제조와 건식 미분체를 제조하는 방법을 설명하고 있으며 이를 참조하여 각 단계에 대해 보다 상세히 설명한다.1 is an exemplary view showing an apparatus for producing a ceramic fine powder for adding synthetic fibers according to the present invention, the natural minerals and ceramics are dispersed in alcohol without firing, and the two-step crushing of the slurry containing the ceramic fine powder The preparation and method of preparing the dry fine powder are described and each step will be described in more detail.

본 발명에 따르면 우선 천연광물 및 세라믹을 소성하지 않고 알콜에 분산시키는데, 구체적으로 천연광물 및 세라믹을 분산제와 같이 알콜에 분산시켜 슬러리를 제조한다. 상기 슬러리의 점도는 10 내지 1000센티포아즈이며 바람직하게는 900센터포이즈 정도로 조절하며, 슬러리의 분산을 위하여 첨가되는 분산제를 수용성아크릴계 계면활성제로서 고체함량에 대햐여 5.0중량% 이하의 양으로 사용하는 것이 바람직하다.According to the present invention, first, natural minerals and ceramics are dispersed in alcohol without firing. Specifically, natural minerals and ceramics are dispersed in alcohol together with a dispersant to prepare a slurry. The viscosity of the slurry is 10 to 1000 centipoise, preferably adjusted to about 900 center poise, and the dispersant added to disperse the slurry is used as the water-soluble acrylic surfactant in an amount of 5.0% by weight or less relative to the solid content. It is preferable.

운모 등과 같은 저 비중 분말의 고체함량은 10 내지 50중량%로 낮게, 알루미나 등과 같은 고 비중 분말의 고체함량은 40 내지 90중량%로 높게하는 것이 바람직하다.The solid content of the low specific gravity powder such as mica and the like is low as 10 to 50% by weight, and the solid content of the high specific gravity powder such as alumina and the like is preferably high to 40 to 90% by weight.

상기와 같이 제조된 슬러리를 분쇄기에서 분쇄된 세라믹 미분체의 크기는 0.04에서 4㎛정도가 되는데, 이를 위하여 사용되는 분쇄매체의 크기는 2.0에서 10.0mm가 적절하게 조절되어 있는 것이 적당하다. 초기에 투입되는 천연광물 및 세라믹의 크기에 따라 분쇄매체의 크기를 결정하는 것이 바람직하다. 2단계 분쇄에서 얻어진 1.0㎛이하의 천연광물 및 세라믹 미분체가 포함된 슬러리는 세라믹 미분체의 응집이 일어나지 않도록 원심분리에 의하여 완전히 1.0㎛이하의 미분체를 함유한 슬러리로 만드는 것이 좋다.The size of the ceramic fine powder pulverized in the above-described slurry in the crusher is about 0.04 to 4㎛, the size of the pulverizing medium used for this is appropriately adjusted to 2.0 to 10.0mm. It is desirable to determine the size of the grinding media according to the size of the natural mineral and ceramics that are initially added. The slurry containing the natural mineral and ceramic fine powder of 1.0 μm or less obtained in the two-stage grinding may be made into a slurry completely containing fine powder of 1.0 μm or less by centrifugation to prevent agglomeration of the ceramic fine powder.

이를 분무건조를 이용하여 건조를 하는데 이때 건조온도는 100에서 300도가 적당하며, 사용되는 세라믹의 종류에 따라 조절하는 것이 좋다. 저비중 고흡습의 세라믹 미분체를 300도, 고비중 저흡습의 세라믹 미분체는 200도 정도가 적당하다. 얻어진 과립을 제트밀을 이용하여 세라믹 미분체를 제조할수 있다.This is dried using spray drying, and the drying temperature is suitable for 100 to 300 degrees, it is good to adjust according to the type of ceramic used. A low specific gravity and high moisture absorption ceramic fine powder is 300 degrees, and a high specific gravity and low moisture absorption ceramic fine powder is about 200 degrees. The obtained granules can be produced in a ceramic fine powder using a jet mill.

상기의 분말화된 미분체 및 완전히 분산된 알콜의 슬러리를 폴리머와 혼합하는 중합공정을 거쳐서 세라믹 합성수지(Resin chip)가 만들어지면 이를 방사기에 투입 용융방사시켜 세라믹 미분체가 함유된 합성섬유를 제조하거나 건조분말화된 미분체를 중합을 거치지 않고 MB(Master Batch)를 만들어 용융방사시 MB칩과 일반칩을 적절히 혼합하면 세라믹 합성섬유를 제조할수 있다.When a ceramic chip is made through a polymerization process of mixing the powdered fine powder and a slurry of fully dispersed alcohol with a polymer, the ceramic chip is added to a spinning machine and melted to prepare a synthetic fiber containing ceramic powder or dried. MB (Master Batch) can be made without polymerizing the powdered fine powder to make ceramic synthetic fiber by mixing MB chip and general chip properly during melt spinning.

폴리머와 세라믹의 혼합중합에 있어서 주의사항은 천연광물과 세라믹의 종류에 따라 폴리머중합점도가 달라진다. 특히 운모의 경우는 일반세라믹 보다 중합점도가 높아진다. 따라서 공정중 중합혼합기의 혼합회전축으로 폴리머점액이 수직으로 휘말려 올라오는 것을 특히 주의하여야 하고 또한 세라믹의 원활한 혼합과 분산을 위하여 중합시 통상 분산제를 사용하는데 분산제는 200도에서 기화하므로 기화시 극미세 세라믹입자와 동반기화하는 현상 때문에 진공배출관을 막아버리는 위험이 따른다 따라서 작업시 분산제는 최소한 줄여 사용하든가 아니면 가능한 사용하지 않는 것이 바람직히다.In the polymerization of polymers and ceramics, the precautions for polymers vary depending on the type of natural mineral and ceramics. In the case of mica, the polymerization viscosity is higher than that of general ceramics. Therefore, pay special attention to the vertical entanglement of polymer slime to the mixing rotation axis of the polymerization mixer during the process. Also, in order to smoothly mix and disperse the ceramic, a dispersant is usually used during polymerization. The entrainment with the particles carries a risk of clogging the evacuation tube. Therefore, it is advisable to use at least a dispersant or not as possible during operation.

용융방사시 약간의 고온방사가 적당하며 스핀드로방식이 유리하다. 이는 POY사에 비하여 경비절감 외에도 운모는 유제를 흡습 및 분해하려는 성질이 있다. 따라서 권취후에 연신하려면 연신공정이 어려워지며 유제의 손실이 커지기 때문이다.또한 운모의 매끄러운 특성상 권취시 사층이 무너지는 현상이 발생하므로 원사의 단면을 삼각형으로 방사하는 것도 하나의 방법이 된다.Some high temperature spinning is suitable for melt spinning, and spin draw method is advantageous. In addition to the cost savings compared to POY, mica has the property of absorbing and decomposing emulsions. This is because the stretching process becomes difficult to stretch after winding and the loss of emulsion increases. In addition, the yarn layer collapses when winding due to the smooth nature of mica.

compound공정시 분말 미분체와 합성수지를 혼합할때 Twinscrew M/C에서 충분히 용융 혼합하고 이때 분산제와 커플링에이전트를 투입하고 수지는 점도와 강도가 좋은 원료를 사용하여야 하며 분말은 최대한 수분을 제거하므로써 IV문제와 균제도문제를 해결해야 한다.When mixing the powder fine powder and the synthetic resin in the compound process, make sufficient melt mixing at Twinscrew M / C. At this time, dispersant and coupling agent should be added, and the resin should be made of raw material with good viscosity and strength. Problems and equalization problems must be solved.
