Description

제전성 폴리에스터 부직포필터의 제조방법Manufacturing method of antistatic polyester nonwoven filter

본 발명은 제진(除塵)시 특히 디스트속에 함유되어 있는 대전성입자를 효과적으로 제거할 수 있는 제전성 부직포필터를 제공하기 위한 개량된 제조방법에 관한 것이다.The present invention relates to an improved manufacturing method for providing an antistatic nonwoven filter capable of effectively removing the charged particles contained in the disc, in particular during vibration damping.

종래 시멘트공장, 제철공장, 제련공장 등의 집진 내지 제진시 그 속에는 대전성(帶電性)입자가 많이 혼재되어 있고 이것이 누적되어 대전으로 인한 화재발생의 원인이 되기도 하였다.When dust collection or dust removal of a cement plant, a steel mill, a smelting plant, etc., a lot of chargeable particles are mixed therein, which may accumulate and cause a fire due to charging.

본 발명은 상기와 같은 집진 내지 제진시 그 속에 혼재하고 있는 대전성입자를 특히 효과적으로 여과 제거시킬 수 있는 부직포필터를 제조하는 방법을 제공하였는바, 그 주요 구성을 상술하면 다음과 같다.The present invention provides a method of manufacturing a nonwoven filter that can effectively filter out the charged particles mixed therein during dust collection or dust removal as described above.

경사에 동선 또는 탄소섬유를 연합한 폴리에스터 방적사로 직성된 “폴리에스터 스크림”(Scrim)을 심포(芯布)로 하여된 폴리에스터 니들펀치 부직포의 일면을 불소 계실리콘수지, 아크릴수지, 폴리비닐아세테이트, 정전방지제, 건식발포제 및 용제로 조성된 조성물로 코팅한 것을 120℃-140℃의 온도에서 건식발포 시킨후 약 160℃의 온도에서 칼렌더링을 행하여 상기의 코팅층을 평활하게 가공하여 본 발명 소기의 부직포필터를 제조한다.Fluorine-based silicone resins, acrylic resins, and polyvinyl chlorides are formed on one side of a polyester needle punch nonwoven fabric made of a polyester fabric with a “Scrim” made of polyester spun yarns incorporating copper wire or carbon fiber on a slope. After coating the composition of the composition consisting of acetate, antistatic agent, dry foaming agent and solvent dry foaming at a temperature of 120 ℃-140 ℃ and calendering at a temperature of about 160 ℃ to smoothly process the coating layer of the present invention Nonwoven fabric filter is prepared.

이상과 같이 구성된 본 발명의 작용, 효과를 상술하면 다음과 같다.Referring to the operation and effect of the present invention configured as described above are as follows.

본 발명에서는 더스트의 흡착제거효과의 증대를 위함과 동시에 많은 양의 더스트가 흡착되었을 때 그 중량을 이겨낼 수 있는 강도를 갖도록 하기 위하여 폴리에스터 섬유를 폴리에스터 스크림(Polyester Scrim) 즉 폴리에스터 방적사로 제직한(粗織物)에 니들펀치식으로 식모한 부직포를 사용하였다.In the present invention, in order to increase the adsorption removal effect of the dust and at the same time a large amount of dust is adsorbed weaving polyester fibers with a polyester scrim (polyester yarn) in order to have a strength that can withstand the weight A non-woven fabric prepared by needle punching was used.

그리고 폴리에스터 자체의 대전성은 물론 더스터중의 대전경향을 방지하기 위하여 대전방지제의 일종인 불소계 실리콘수지와 공지의 대전방지제가 혼합된 조성물을 상기의 부직포의 여과작용면에만 도층하도록 하였으며, 이 도층으로 인한 여과방해 즉, 통기성방해를 제거하기 위하여 공지의 건식발포제를 상기조성물에 혼입시켜 건식발포를 행하였다.In order to prevent the charging property of the polyester itself as well as the charging tendency in the dust, a composition in which a fluorine-based silicone resin, which is a kind of an antistatic agent, and a known antistatic agent is mixed on only the filtration surface of the nonwoven fabric. In order to remove filtration interference, that is, air permeability, a known dry foaming agent was incorporated into the composition to perform dry foaming.

또 이코팅층에 흡착된 더스터가 쉬이 박리될 수 있게하기 위하여 대전방지제로 사용한 실리콘수지는 특히 불소계실리콘수지를 선택하였으며 아크릴수지는 상기의 코팅층의 피막형성주체이며 이 피막은 폴리비닐아세데이트에 의하여 부직포에 견고하게 접착되도록 하였다.The silicone resin used as an antistatic agent was selected in particular to prevent the dust adsorbed on the coating layer from being easily peeled off. The acrylic resin is the film forming agent of the coating layer, which is formed by polyvinylacetate. It was made to adhere firmly to the nonwoven fabric.

본 발명에서 사용된 용제는 수지용해용이다. 그러나 상기와 같은 피막의 형성만으로는 그 표면에 흡착된 더스터가 쉬이 탈리되지 않으므로 코팅층에 칼렌더체리함으로써 그 표면을 평활하게 만들어 흡착된 더스터가 더욱 효과적으로 탈리될 수 있도록 하였다.The solvent used in the present invention is a resin dissolution. However, since the dust adsorbed on the surface is not easily detached by the formation of the film as described above, the surface is smoothed by calendering the coating layer so that the adsorbed dust can be detached more effectively.

또한 부직포의 심포(芯布 : scrim)중 경사는 폴리에스터 방적사와 동선 내지 탄소섬유사 등을 연합하여 구성한 것은 더스터속에 혼재하는 대전성입자에 의하여 발생된 정전기를 이 동선 내지 탄소섬유사를 통하여 제거시키기 위하여서이다.In addition, the slope of the nonwoven fabric is composed of polyester spun yarn and copper wire or carbon fiber yarns. The static electricity generated by the electrostatic particles mixed in the dust is transferred through the copper wire or carbon fiber yarn. To get rid of.

이상과 같이 본 발명의 방법에 의하여 제조된 부직포필터를 사용하면 특히 시멘트공장, 제철공장, 제련공장 등 대형집진(또는 제진)장치 속에 혼재하는 대전성입자로부터 발생되는 정전기를 함께 제거시킬 수가 있어 종래 이들로 인한 화제발생등의 우려를 해결할 수 있는 효과가 있다.By using the nonwoven filter manufactured by the method of the present invention as described above, in particular, it is possible to remove the static electricity generated from the electrostatic particles mixed in the large dust collector (or vibration damping) device, such as cement plants, steel mills, smelting plants, etc. There is an effect that can solve the concern such as the occurrence of the topic.
