Description
본 발명은 폴리프로필렌의 일반 완전연소를 유도하고, 연소시 불이 붙은 상태에서의 드롭성을 억제시키며, 그을음성이 없는 완전연소형 폴리프로필렌 수지 조성물에 관한 것이다.The present invention relates to a complete combustion type of polypropylene resin composition which induces general complete combustion of polypropylene, suppresses drop property in a ignited state during combustion, and is free of soot.
난연성 폴리프로필렌으로 사용되는 조성물은 전기적인 절연특성과 제조상의 편리함을 위한 기계적특성과 내화학적 특성 등이 우수하여 전선 및 통신용 케이블등의 개재물로 널리 사용되고 있는데 난연 특성을 부여하기 위해 할로겐 화합물의 난연제를 사용하는 것이 일반화된 기술이다. The composition used as flame-retardant polypropylene is widely used as an inclusion in wires and communication cables because of its excellent electrical insulation properties and mechanical and chemical resistance properties for manufacturing convenience. Flame retardants of halogen compounds are used to impart flame retardant properties. Using is a generalized technique.
그러나, 이와 같이 할로겐 화합물이 첨가된 난연성 폴리프로필렌 조성물로 형성된 제품은 화재등으로 고열과 화염에 노출되면 유독한 가스와 짙은 연기를 발생시키게되어 인체에 치명적인 악영향을 끼치게된다. However, a product formed of a flame-retardant polypropylene composition in which a halogen compound is added in this way causes toxic gases and dense smoke when exposed to high heat and flames due to a fire, thereby causing a fatal adverse effect on the human body.
즉, 화재발생시에 폴리프로필렌 조성물이 연소하여 다량의 유해 가스가 발생하게되면 유독 가스에 의한 중독 또는 짙은 연기에 의한 질식등으로 사망에 이를 수도 있는 치명적인 단점이 있었다. In other words, if a large amount of harmful gas is generated by burning the polypropylene composition during a fire, there is a fatal disadvantage that may result in death due to poisoning by toxic gas or asphyxiation by heavy smoke.
따라서, 난연성 폴리프로필렌 조성물의 이와 같은 단점을 개선하기 위해 할로겐계 난연제를 제외하고 금속수산화물을 난연성 충전제로 이용함으로 저공해와 난연화를 이루도록 하였다. Therefore, in order to improve such disadvantages of the flame retardant polypropylene composition, except for the halogen-based flame retardant, the metal hydroxide is used as the flame retardant filler to achieve low pollution and flame retardancy.
그러나 폴리프로필렌에 비할로겐계 난연제를 사용할 때에는 많은 양의 난연제가 투입되어 폴리프로필렌원료 고유 물성을 저해하여 그 용도가 매우 한정되어 있었다.However, when a non-halogen flame retardant is used for polypropylene, a large amount of flame retardant is added, and the use of the polypropylene raw material is impaired.
한편, 다양한 난연제의 사용에 따라 폴리프로필렌의 난연성은 증가하였지만 불이 발생한 경우에는 약한 불에도 유독가스가 발생하는 문제가 여전히 존재하였다.On the other hand, although the flame retardancy of polypropylene increased with the use of various flame retardants, there was still a problem that toxic gas was generated even in a weak fire when a fire occurred.
따라서 폴리프로필렌 조성물로 이루어진 플라스틱의 연소시 완전연소되지 않는 잔류물이 떨어져 그로인한 2차 화재가 발생되지 않도록 폴리프로필렌의 완전 연소로 유도하고, 연소시 유독한 연기 및 그을음을 방지하여 화재시에 탈출 할 수 있는 시야를 확보하는 물질이 필요하였다.Therefore, the combustion of plastics made of polypropylene composition leads to the complete combustion of polypropylene so that the second fire does not occur due to the falling off of the residue, and escapes in case of fire by preventing toxic smoke and soot during combustion. There was a need for a material that ensures visibility.
따라서 본 발명의 목적은 폴리프로필렌의 일반 완전연소를 유도하고, 연소시 불이 붙은 상태에서의 드롭성을 억제시키며 그을음성이 없는 완전연소형 폴리프로필렌 수지 조성물을 제공함에 있다.Accordingly, an object of the present invention is to provide a complete combustion type of polypropylene resin composition which induces general complete combustion of polypropylene, suppresses drop property in a ignited state during combustion, and is free of soot.
상기와 같은 목적을 달성하기 위한 본 발명의 그을음성이 없는 폴리프로필렌 수지 조성물은 용융지수(D1238) 1.0g/10분 인 호모 폴리프로필렌 수지 100중량부에 대하여 수산화마그네슘(Mg(OH)2) 5-25 중량부와, 생석회(CaO) 5-25 중량부, CaCO3의 입자크기 1㎛의 50-70 중량부를 혼합한 것을 특징으로 한다.The soot-free polypropylene resin composition of the present invention for achieving the above object is magnesium hydroxide (Mg (OH) 2 ) 5 with respect to 100 parts by weight of the homopolypropylene resin of 1.0g / 10 minutes of melt index (D1238) 5 It is characterized by mixing -25 parts by weight, 5-25 parts by weight of quicklime (CaO), 50-70 parts by weight of the particle size of CaCO 3 1㎛.
폴리프로필렌 중합체는 용융유속(MFR) ASTM-D-1238에 준한 방법으로 측정하여 0.5~2g/10분이 폴리프로필렌이 사용되고, 바람직하기로는 용융유속이 0.5~1g/10분을 갖는 호모 폴리프로필렌 및 임펙트 코 폴리머가 사용된다. The polypropylene polymer is a polypropylene polymer having an melt flow rate (MFR) of 0.5 to 2 g / 10 minutes as measured according to ASTM-D-1238, preferably a homo polypropylene having an melt flow rate of 0.5 to 1 g / 10 minutes and an impact. Copolymers are used.
본 발명에서 사용되는 수산화마그네슘(Mg(OH)2 )은 폴리프로필렌의 연소 속도를 저하시키고, 폴리프로필렌에 투입시 가열되면 온도가 상승하는 과정에서 분해되어 물을 방출하고 물 방출후는 무기물로 남게된다. 이러한 수산화마그네슘의 비중은 2.36이고, BULK DENSITY는 0.35g/㎤~0.5g/㎤이며, 폴리프로필렌에 대하여 5~25 중량부로 사용되는 것이 바람직하다. 이러한 수산화마그네슘은 그 탈수 온도가 350℃정도이고 압출 성형시 탈수 발포하는 것은 장점이 있다.Magnesium hydroxide (Mg (OH) 2 ) used in the present invention lowers the combustion rate of polypropylene, and when heated in the polypropylene, is decomposed in the process of increasing the temperature to release water and remain as inorganic matter after the water is released. do. The magnesium hydroxide has a specific gravity of 2.36, a bulk density of 0.35 g / cm 3 to 0.5 g / cm 3, and preferably 5 to 25 parts by weight based on polypropylene. Such magnesium hydroxide has an advantage of having a dehydration temperature of about 350 ° C. and dewatering foaming during extrusion molding.
또한, 본 발명에서 사용되는 생석회(CaO)는 폴리프로필렌 수지에 대하여 5~25 중량부로 사용되는 것이 바람직하다. 이와 같이 혼합되는 생석회는 수산화마그네슘에 포함되어 있는 수분 또는 공기나 주위에서 수분(H2O)을 강력하게 흡습하여 200℃정도의 열을 내며 소석회로 반응하면서 전체 혼합물에서 연소효과를 향상시킨다[CaO + H2O -> Ca(OH)2 + 200℃]. 즉, 연소시 가열된 수산화마그네슘에서 발 생된 수분(H2O)에 의해 유독 연기의 발생을 줄일 수 있고, 발생된 수분이 다시 생석회와 반응하여 2차 열이 발생하여 완전연소를 촉진시킬 수 있다.In addition, the quicklime (CaO) used in the present invention is preferably used in 5 to 25 parts by weight based on the polypropylene resin. The quicklime mixed in this way strongly absorbs moisture (H 2 O) contained in magnesium hydroxide or air or surroundings and generates about 200 ° C and reacts with calcination to improve the combustion effect in the entire mixture. + H 2 O-> Ca (OH) 2 + 200 ° C]. That is, the generation of toxic fumes can be reduced by the moisture (H 2 O) generated from the heated magnesium hydroxide during combustion, and the generated moisture can be reacted with quicklime again to generate secondary heat to promote complete combustion. .
탄산칼슘(CaCO3)은 825℃에서 분해되며, 가열하면 이산화탄소를 발생하고 생석회를 얻는다.[CaCO3 -> CaO + CO2] 이러한 탄산칼슘은 폴리프로필렌에 첨가되어 연소시 NON-DRIP성을 향상시키는 장점이 있으나, 폴리프로필렌에 대한 탄산칼슘의 첨가중량이 70중량부 이상 함유이면 연신과정에서 작업성이 저하되는 단점이 있다.Calcium carbonate (CaCO 3 ) decomposes at 825 ° C., generates carbon dioxide and gets quicklime when heated. [CaCO 3- > CaO + CO 2 ] These calcium carbonates are added to polypropylene to improve NON-DRIP properties during combustion. However, if the added weight of the calcium carbonate to the polypropylene containing 70 parts by weight or more, there is a disadvantage that the workability is lowered in the stretching process.
<실시예 1><Example 1>
폴리프로필렌 100g에 탄산칼슘(CaCO3) 100g를 혼합하고 배합기(HANSELL MIXER)에서 15분동안 교반 혼합 후 통상의 압출기를 사용하여 용융 압출시켜 펠렛을 제조하여 그 물성을 측정하여 표 1에 나타내었다.100 g of polypropylene was mixed with 100 g of calcium carbonate (CaCO 3 ), stirred and mixed for 15 minutes in a blender (HANSELL MIXER), and melt-extruded using a conventional extruder to prepare pellets. The physical properties thereof are shown in Table 1 below.
<실시예 2><Example 2>

<실시예 3><Example 3>
폴리프로필렌 100g에 탄산칼슘(CaCO3) 70g, 수산화마그네슘(Mg(OH)2) 10g, 생석회 10g를 혼합하고 실시예 1과 동일한 조건하에서 용융 압출시켜 펠렛을 제조 하여 그 물성을 측정하여 표 1에 나타내었다.70 g of calcium carbonate (CaCO 3 ), 10 g of magnesium hydroxide (Mg (OH) 2 ), and 10 g of quicklime were mixed with 100 g of polypropylene, and pellets were prepared by melt extrusion under the same conditions as in Example 1 to measure the physical properties thereof. Indicated.
<실시예 4><Example 4>
폴리프로필렌 100g에 탄산칼슘(CaCO3) 60g, 수산화마그네슘(Mg(OH)2) 10g, 생석회 10g를 혼합하고 실시예 1과 동일한 조건하에서 용융 압출시켜 펠렛을 제조하여 그 특성을 측정하여 표 1에 나타내었다. 또한, 제작된 폴리프로필렌 수지의 특성을 표 2에 나타내었다.100 g of polypropylene was mixed with 60 g of calcium carbonate (CaCO 3 ), 10 g of magnesium hydroxide (Mg (OH) 2 ), and 10 g of quicklime. Indicated. In addition, the properties of the produced polypropylene resin are shown in Table 2.
표 1에 나타난 바와 같이, 폴리프로필렌과 탄산칼슘만을 혼합한 실시예 1의 경우에는 연소시 완전히 연소되지 않는 것을 알 수 있으며, 폴리프로필렌의 연신과정에서 작업성이 저하되는 문제가 발생하였다. 그러나, 폴리프로필렌, 탄산칼슘 및 수산화마그네슘을 혼합한 실시예 2 및 3의 경우에도 연소시 완전 연소되지만, 연신과정에서 작업성이 저하되는 문제가 있으며, 폴리프로필렌, 탄산칼슘, 수산화마그네슘 및 생석회를 혼합한 실시예 4에서는 연소시 완전히 연소될 뿐만아니라 연신과정에서도 작업성이 양호하였다.As shown in Table 1, in the case of Example 1, in which only polypropylene and calcium carbonate were mixed, it was found that combustion did not occur completely during combustion, resulting in a problem of deterioration in workability during the stretching process of polypropylene. However, in the case of Examples 2 and 3 in which polypropylene, calcium carbonate and magnesium hydroxide are mixed, they are completely combusted during combustion, but there is a problem of deterioration in workability during the stretching process, and polypropylene, calcium carbonate, magnesium hydroxide and quicklime In Example 4 mixed, not only completely burned during combustion but also good workability in the drawing process.
또한, 표 2에 도시된 바와 같이, 실시예 4에서 제조된 폴리프로필렌 펠렛은 일반 공업용으로 사용할 수 있는 물성을 갖는 것을 알 수 있다.In addition, as shown in Table 2, it can be seen that the polypropylene pellets prepared in Example 4 have physical properties that can be used for general industrial purposes.
이상에서 살펴본 바와 같이, 본 발명의 완전연소형 폴리프로릴렌 수지 조성물은 폴리프로필렌의 완전연소를 유도하여 연소시 잔여물질의 드롭성을 억제시키고 그을음성이 없는 장점이 있다.As described above, the completely combustible polypropylene resin composition of the present invention induces the complete combustion of polypropylene, thereby suppressing the drop property of the residual material during combustion, and has the advantage of no sootness.
