Description
본 발명은 난연통기성 필름용 컴파운드 조성물 및 이를 이용한 필름의 제조방법에 관한 것으로서, 보다 상세하게는 폴리올레핀계 수지, 무기난연제, 활제, 산화방지제 및 이산화티타늄을 포함하는 조성물 및 이를 이용하여 난연성이 우수한 필름을 제조하는 방법에 관한 것이다. The present invention relates to a compound composition for flame-retardant breathable film and a method for producing a film using the same, more specifically, a composition comprising a polyolefin resin, an inorganic flame retardant, a lubricant, an antioxidant and titanium dioxide and a film having excellent flame retardancy using the same It relates to a method of manufacturing.
최근 폴리올레핀 수지 및 무기충진제를 이용하여 제조되는 통기성 또는 다공성 필름은 각종 위생 용품, 의료 용품, 건축자재 및 전지 격리막 등의 재료로 널리 이용되고 있으며, 이러한 필름의 제조와 관련된 다양한 방법들이 알려져 있다. 상기 통기성 또는 다공성 필름을 제조하는 방법으로 여러 가지가 알려져 있으나, 그 중에서도 경제성이 가장 높고 현재 상업화가 진행되어 있는 방법은 폴리올레핀 수지에 무기충진제를 혼합하여 필름을 성형한 후, 일축 또는 이축 연신에 의해 수지와 충진제 사이의 계면 분리를 통해 미세한 구멍을 형성시키는 방법이다. Recently, breathable or porous films prepared using polyolefin resins and inorganic fillers have been widely used as materials for various sanitary articles, medical supplies, building materials, and battery separators, and various methods related to the manufacture of such films are known. Various methods are known as a method of manufacturing the air permeable or porous film, but among them, the most economical method and currently commercialized are the method of mixing an inorganic filler with a polyolefin resin to form a film, followed by uniaxial or biaxial stretching. It is a method of forming fine pores through the interface separation between the resin and the filler.
보다 구체적으로 상기 필름을 형성하는 종래 기술들을 검토하여 보면, 첫번 째 방식으로서 유럽공개특허 제66,672호(1982), 동 특허 제307,116호(1988), 동 특허 제 459,142호(1991), 또는 동 특허 제 779,325호(1997) 등에서 나타나는 바와 같이 폴리올레핀과 무기충진제에 지방산류 성분을 첨가하여 필름의 유연성을 증가시키거나, 또는 필름의 종적 방향과 횡적 방향의 물성상의 불균형을 해소하는 방법을 들 수 있다. 이러한 첨가제의 사용은 압출 과정에서 고함량의 무기충진제의 혼합과 분산을 가능하게 하며, 필름 가공시 균일한 연신물을 생산할 수 있도록 하는데 중요한 역할을 하고 있다. In more detail, the prior art of forming the film, as a first method, European Patent No. 66,672 (1982), Patent No. 307,116 (1988), Patent No. 459,142 (1991), or the patent As shown in No. 779, 325 (1997) and the like, a method of increasing the flexibility of the film by adding fatty acid components to the polyolefin and the inorganic filler, or eliminating the imbalance of the physical properties in the longitudinal and transverse directions of the film. The use of such additives enables the mixing and dispersing of high content inorganic fillers in the extrusion process, and plays an important role in producing a uniform stretch during film processing.
또한, 상기 방식과는 구별되는 것으로 유럽공개특허 제232,060호(1987)에 나타난 바와 같이 필름의 후가공 시에 엠보 처리와 같은 특정 기술을 사용함으로써 통기성 필름의 기계적 강도를 조절하거나 혹은 미국특허 제 4,777,073호에 나타난 바와 같이 투습도를 증가시키고 인열 강도를 향상시키는 방법도 알려져 있다. In addition, as described in EP 232,060 (1987), which is distinguished from the above method, it is possible to control the mechanical strength of the breathable film by using a specific technique such as embossing in the post-processing of the film, or US Patent No. 4,777,073. As also shown, a method of increasing the moisture permeability and improving the tear strength is also known.
그러나 상기의 방식은 필름의 통기성을 부여하기 위하여 탄산칼슘과 같은 무기물을 사용하고 있지만, 무기물 자체의 난연성을 제외하고는 필름 자체의 난연효과를 나타내지 않기 때문에 난연성이 요구되는 용도에 적용하기에는 한계를 갖고 있다. However, the above method uses inorganic materials such as calcium carbonate to impart air permeability of the film. However, since the flame retardant effect of the film itself is not exhibited except for the flame retardancy of the inorganic material itself, there is a limitation in applying it to applications requiring flame retardancy. have.
한편, 보다 최근에는 난연 통기성 필름을 제조하기 위하여 할로겐타입의 난연제를 첨가하여 사용하는 경우가 있으나, 할로겐타입의 난연제는 인체유해물질로 규정되어 인체에 접촉되는 용도에의 사용이 규제될 전망이다. On the other hand, more recently, in order to manufacture a flame-retardant breathable film may be used by adding a halogen-type flame retardant, halogen-type flame retardant is defined as a human harmful substance is expected to be regulated for use in contact with the human body.
이에, 본 발명자들은 상기 문제점을 해결하기 위하여 예의 연구한 결과, 폴리올레핀계 수지에 고온에서 화학반응에 의한 물을 생성하는 무기난연제를 첨가하여 사용함으로써, 필름제조 및 연신시 계면 분리에 의한 미세구멍 생성을 통하여 통기성이 부여되고, 화염에 노출되는 경우에는 무기난연제에서 화학반응에 의한 물이 발생되어 난연성을 발현하는 필름을 제공하기에 이르렀다. Accordingly, the present inventors earnestly studied to solve the above problems, and by using an inorganic flame retardant which generates water by chemical reaction at a high temperature to the polyolefin resin, micropores are generated by interfacial separation during film production and stretching. When the air permeability is imparted, and when exposed to a flame, water is generated by a chemical reaction in the inorganic flame retardant to provide a film that exhibits flame retardancy.
상기 목적을 달성하기 위한 본 발명의 한 측면은 폴리올레핀계 수지 100 중량부를 기준으로 하여 무기난연제 50 내지 200 중량부, 무기충진제 0 내지 200 중량부, 활제 0.05 내지 3 중량부, 산화방지제 0.01 내지 3 중량부, 및 이산화티타늄 0 내지 3 중량부를 포함하는 것을 특징으로 하는 난연 통기성 필름용 컴파운드 조성물에 관한 것이다.

상기 목적을 달성하기 위한 본 발명의 다른 한 측면은 상기 조성물을 이용하여 난연 통기성 필름을 제조하는 방법에 관한 것이다. Another aspect of the present invention for achieving the above object relates to a method for producing a flame retardant breathable film using the composition.
본 발명에 따른 난연 통기성 필름을 제조하기 위해 사용되는 조성물의 제1성분으로는 폴리올레핀계 수지가 포함된다. 상기 폴리올레핀계 수지로는 최종 제품의 요구 물성에 따라 저밀도 폴리에틸렌, 선형저밀도 폴리에틸렌, 고밀도 폴리에틸렌, α-올레핀계 폴리머, 호모 폴리프로필렌, 랜덤 폴리프로필렌, 또는 임팩트 폴리프로필렌 중 1종 또는 2종 이상이 혼합된 수지를 사용하는 것이 바람직하다. The first component of the composition used to prepare the flame retardant breathable film according to the present invention includes a polyolefin resin. As the polyolefin resin, one or two or more of low density polyethylene, linear low density polyethylene, high density polyethylene, α-olefin polymer, homo polypropylene, random polypropylene, or impact polypropylene may be mixed according to the required physical properties of the final product. It is preferable to use the prepared resin.
또한, 본 발명에 따른 필름용 조성물의 제2성분으로 무기충진제가 포함되는데, 탄산칼슘, 황산 바륨 또는 이들의 혼합물이 무기충진제로 사용될 수 있으며, 제1성분인 폴리올레핀 수지 100 중량부에 대해 0 내지 200 중량부의 양으로 조성물에 포함되는 것이 바람직하다. 나아가 상기 무기충진제는 평균 입도가 0.7 내지 5 ㎛의 범위의 것을 사용하는 것이 바람직한데, 이는 평균 입도가 0.7 ㎛보다 작으면 통기성 컴파운드 제조 시에 혼련성이 떨어져 원하는 물성을 나타낼 수 없는 문제점이 발생할 수 있고, 평균 입도가 5 ㎛보다 크면 통기성 필름 제조 시에 구멍 발생 빈도가 증가하여 불량 발생이 증가될 우려가 있기 때문이다. 한편, 상기 무기 충진제는 코팅하지 않은 상태로 사용하거나 또는 선택적으로 스테아린산을 포함하는 지방산 또는 스테아린산 염을 포함하는 지방산 금속염으로 코팅하여 사용할 수도 있다. In addition, an inorganic filler is included as a second component of the composition for a film according to the present invention. Calcium carbonate, barium sulfate or a mixture thereof may be used as the inorganic filler, and may be 0 to 100 parts by weight based on 100 parts by weight of the polyolefin resin as the first component. It is preferably included in the composition in an amount of 200 parts by weight. Furthermore, it is preferable to use the inorganic filler having an average particle size in the range of 0.7 to 5 μm. If the average particle size is less than 0.7 μm, there may be a problem in that the kneading property is insufficient in the preparation of a breathable compound and thus the desired physical properties cannot be exhibited. This is because when the average particle size is larger than 5 μm, the frequency of occurrence of holes increases during manufacture of the breathable film, which may increase the occurrence of defects. On the other hand, the inorganic filler may be used uncoated or optionally coated with a fatty acid containing stearic acid or a fatty acid metal salt containing a stearic acid salt.
또한, 본 발명에 따른 필름용 조성물의 제3성분인 무기난연제로는 수산화마그네슘, 수산화알루미늄 또는 이들의 혼합물을 사용할 수 있는데, 그 함량은 제1성분인 폴리올레핀 수지 100 중량부에 대해 50 내지 200 중량부의 양으로 조성물에 포함되는 것이 바람직하다. 무기난연제의 첨가량이 50 중량부보다 작으면 화염에 노출시 난연효과가 미미할 수 있고, 200 중량부보다 크면 난연효과는 크지만 경제성이 문제가 될 수 있기 때문이다. 보다 바람직하게는, 무기난연제가 제1성분인 폴리올레핀 수지 100 중량부에 대해 50 내지 100 중량부로 본 발명의 조성물에 포함될 수 있다.In addition, as the inorganic flame retardant which is the third component of the film composition according to the present invention, magnesium hydroxide, aluminum hydroxide or a mixture thereof may be used, and the content thereof is 50 to 200 weight parts based on 100 parts by weight of the polyolefin resin as the first component. It is preferred to be included in the composition in negative amounts. If the amount of the inorganic flame retardant is less than 50 parts by weight, the flame retardant effect may be insignificant upon exposure to the flame. More preferably, the inorganic flame retardant may be included in the composition of the present invention from 50 to 100 parts by weight based on 100 parts by weight of the polyolefin resin as the first component.
나아가 상기 무기난연제는 평균입도가 0.5 내지 5 ㎛의 범위의 것을 사용하는 것이 바람직한데, 평균 입도가 0.5 ㎛보다 작으면 혼련성이 떨어져 원하는 물성을 나타낼 수 없고, 평균 입도가 5 ㎛보다 크면 통기성 필름 제조 시에 구멍 발생 빈도가 증가하여 불량 발생이 증가되는 문제가 있다. Furthermore, the inorganic flame retardant is preferably used in the range of 0.5 to 5 ㎛ average particle size, if the average particle size is less than 0.5 ㎛ can not exhibit the desired physical properties, the average particle size is greater than 5 ㎛ breathable film There is a problem in that the occurrence of defects is increased by increasing the frequency of occurrence of holes during manufacture.
본 발명의 가장 특징적인 성분이라 할 수 있는 무기난연제는 판상형의 무기입자로 폴리올레핀과 함께 혼합 제조 후 연신필름 제조시 계면간 박리가 가능하고 필름의 통기성을 발현할 수 있다. 뿐만 아니라 본 발명에 사용되는 무기난연제는 단일 분자 내에 2 개 이상의 수산기가 있고, 분해 및 탈수개시온도가 수산화마그네슘의 경우 340℃, 수산화알루미늄의 경우 230℃이므로, 화염 등 고온에 노출 시에는 하기 반응식 1 또는 반응식 2와 같은 화학 분해반응에 의하여 수분이 생성됨으로써 보다 효과적인 난연성을 제공할 수 있다. The inorganic flame retardant, which is the most characteristic component of the present invention, is a plate-shaped inorganic particle that can be peeled between interfaces when preparing a stretched film after mixing with polyolefin and expressing air permeability of the film. In addition, the inorganic flame retardant used in the present invention has two or more hydroxyl groups in a single molecule, the decomposition and dehydration start temperature is 340 ℃ for magnesium hydroxide, 230 ℃ for aluminum hydroxide, so when exposed to high temperatures such as flame Moisture is produced by a chemical decomposition reaction such as 1 or Scheme 2 can provide more effective flame retardancy.
본 발명에 따른 필름용 조성물의 제4성분으로 포함되는 것은 가공상의 활제로서, 특별히 제한되는 것은 아니나 보다 구체적인 예로서는 스테아린산 칼슘 또는 스테아린산 아연을 들 수 있으며, 이들이 단독 또는 혼합되어 사용될 수 있다. 상기 활제는 제1성분인 폴리올레핀 수지 100 중량부에 대해 0.05 내지 3 중량부의 양으로 포함될 수 있는데, 이는 상기 활제의 양이 0.05 중량부 보다 작으면 가공시 활제의 역할을 충분히 할 수 없고 3 중량부 보다 크면 통기성 필름 성형 시 다이 빌드-업(Die Build-up) 현상이 심하게 나타나 생산 효율이 감소할 수 있기 때문이 다. Included as the fourth component of the composition for a film according to the present invention is a processing lubricant, and is not particularly limited, but specific examples thereof include calcium stearate or zinc stearate, and these may be used alone or in combination. The lubricant may be included in an amount of 0.05 to 3 parts by weight based on 100 parts by weight of the polyolefin resin as the first component, which may not be sufficient as a lubricant in processing if the amount of the lubricant is less than 0.05 parts by weight. Larger die build-up may occur when forming breathable films, which may reduce production efficiency.
본 발명에 따른 필름용 조성물의 제5성분으로 포함되는 것은 산화방지제로서 특별히 제한되는 것은 아니나, 페놀계 산화방지제나 인산계 산화방지제를 단독 또는 두 가지를 동시에 사용할 수 있다. 상기 산화방지제의 보다 바람직한 사용량은 제1성분인 폴리올레핀 수지 100 중량부에 대해 0.01 내지 3 중량부인데, 그 양이 0.01 중량부 보다 작으면 산화방지 효과를 바라는 만큼 나타낼 수 없고, 3 중량부 보다 크면 산화방지 효과의 증가를 더 이상 기대할 수 없어서 비효율적이기 때문이다. Included as the fifth component of the composition for a film according to the present invention is not particularly limited as an antioxidant, but may be used alone or two at the same time phenolic antioxidant or phosphoric acid antioxidant. More preferably, the amount of the antioxidant is 0.01 to 3 parts by weight based on 100 parts by weight of the polyolefin resin as the first component. If the amount is less than 0.01 parts by weight, the amount of the antioxidant may not be expressed as much as desired. This is because an increase in the antioxidant effect can no longer be expected and is inefficient.
본 발명에 따른 필름용 조성물의 제6성분으로 포함되는 이산화티타늄은 필름의 백색도나 은폐력을 증가시키기 위해 첨가하는 것으로서 상기 제1성분인 폴리올레핀 수지 100 중량부에 대해 0 내지 3 중량부로 포함되는 것을 특징으로 한다. Titanium dioxide included as a sixth component of the composition for a film according to the present invention is added to increase the whiteness or hiding power of the film, and is included in an amount of 0 to 3 parts by weight based on 100 parts by weight of the first polyolefin resin. It is done.
상기와 같이 이루어진 컴파운드 조성물을 T-다이 압출기로 필름상으로 압출하면서 일축 또는 이축 연신하면, 통기성 필름의 기계적 물성이 개선됨과 동시에 연신 과정에서 계면 분리로 인하여 통기성을 갖는 동시에, 화재발생시 필름 내에 함유된 무기난연제에서 수분이 발생하여 난연효과를 나타내는 통기성 필름이 제조된다. When the compound composition made as described above is uniaxially or biaxially stretched with a T-die extruder while being extruded into a film, the mechanical properties of the breathable film are improved, and at the same time, it is breathable due to interfacial separation in the stretching process and contained in the film during a fire. Moisture is generated from the inorganic flame retardant to produce a breathable film exhibiting a flame retardant effect.
