본 발명은 인장특성이 우수한 폴리프로필렌 무기난연제 복합수지 조성물에 관한 것으로서, 폴리프로필렌 수지 30 ~ 40 중량%와 수산화 마그네슘 무기난연제 60 ~ 70 중량%로 배합함으로써 난연특성을 유지하면서 동시에 기계적 특성 중 인장특성이 매우 우수하여 전선재료 및 자동차 부품, 산업용 부품 등에 사용될 수 있는 난연성 폴리프로필렌 복합수지 조성물에 관한 것이다.The present invention relates to a polypropylene inorganic flame retardant composite resin composition having excellent tensile properties, comprising 30 to 40% by weight of polypropylene resin and 60 to 70% by weight of magnesium hydroxide inorganic flame retardant to maintain flame retardant properties and at the same time tensile properties of mechanical properties This very excellent relates to a flame retardant polypropylene composite resin composition that can be used in electric wire materials and automotive parts, industrial parts and the like.

폴리프로필렌 수지는 우수한 가공특성, 내약품성, 내후성, 기계적 강도로 인해 가정용 전기제품, 건축자재, 내부 장식재, 자동차 부품 등의 분야에서 폭넓게 사용되고 있으며, 본래 인화성 물질이지만 난연특성을 부여하기 위하여 각종 유기계 또는 무기계 난연제를 첨가하여 사용하고 있다.Polypropylene resin is widely used in household electrical appliances, building materials, interior decoration materials, automobile parts, etc. due to its excellent processing properties, chemical resistance, weather resistance, and mechanical strength. An inorganic flame retardant is added and used.

이러한 난연제를 포함하는 난연성 폴리프로필렌 수지 조성물의 예로서는 수산화 마그네슘, 수산화 알루미늄 같은 함수 무기화합물을 폴리프로필렌 수지에 첨 가하여 수득한 조성물(일본 특허공개공보 소 53-92855호, 소 54-29350호, 소 54-77685호, 소 56-26945호), 할로겐계 화합물(예 : 데카브로모디페닐, 에테르 또는 도데카클로로-도데카클로로-도데카하이드로메타노디벤조사이클로옥텐) 및 분말활석, 고령토, 천청석, 실리카 및 규조암으로 이루어진 그룹 중에서 선택된 하나 이상의 무기 충전재를 폴리프로필렌 수지에 첨가하여 수득한 조성물(일본 특허공보 소 55-30739호) 등이 있다..Examples of the flame retardant polypropylene resin composition containing such a flame retardant include a composition obtained by adding a hydrous inorganic compound such as magnesium hydroxide and aluminum hydroxide to a polypropylene resin (Japanese Patent Publication Nos. 53-92855, 54-29350, 54) -77685, Sub 56-26945), halogenated compounds (e.g., decabromodiphenyl, ether or dodecachloro-dodecachloro-dodecahydromethanodibenzocyclooctene) and powder talc, kaolin, celestial stone, And compositions obtained by adding at least one inorganic filler selected from the group consisting of silica and diatomite to a polypropylene resin (Japanese Patent Publication No. 55-30739).

할로겐계 화합물의 경우 난연제로 사용되는 경우 유발되는 환경적인 문제로 인하여 할로겐계 화합물의 난연제 사용은 규제되는 추세이며, 수산화 마그네슘 및 수산화 알루미늄과 같은 무기난연제가 가장 친환경적인 난연제로 인식되며 다량 사용되고 있다. 그러나, 난연성이 높은 조성물을 제조하기 위해 폴리프로필렌 수지에 수산화 마그네슘과 같은 극성 무기충전재를 다량 첨가하여 제조한 복합수지는 매트릭스와 무기입자간 극성차이로 인하여 분산성상이 매우 불규칙하며 입자응집이 발생하여 성형성 및 기계적 물성이 매우 저하되며, 특히 인장물성 중 파단신율이 급격히 저하되는 문제가 있어 실제 산업적으로 이용시 큰 난점으로 작용되고 있다.In the case of halogen-based compounds, the use of flame-retardants of halogen-based compounds has been regulated due to environmental problems caused when used as flame retardants, and inorganic flame retardants such as magnesium hydroxide and aluminum hydroxide are recognized as the most environmentally friendly flame retardants and are used in large quantities. However, composite resins prepared by adding a large amount of polar inorganic fillers such as magnesium hydroxide to polypropylene resins to prepare highly flame retardant compositions have very irregular dispersibility due to polarity difference between the matrix and inorganic particles and particle aggregation occurs. The moldability and mechanical properties are very deteriorated, and in particular, the elongation at break is sharply lowered in the tensile properties, which is a great difficulty in actual industrial use.

이에, 본 발명자들은 폴리프로필렌 수산화마그네슘 무기난연제 수지 조성물이 갖는 문제점을 해결하기 위하여 연구 노력한 결과, 무기난연제 표면을 폴리실록산 화합물 처리를 통한 폴리프로필렌으로 구성되는 매트릭스 수지와의 극성차이를 최소화하여 기계적 물성 중 인장특성이 우수한 폴리프로필렌계 무기난연제 복합수 지 조성물을 개발함으로써 본 발명을 완성하게 되었다.Accordingly, the present inventors have made efforts to solve the problems of the polypropylene magnesium hydroxide inorganic flame retardant resin composition, and as a result, the surface of the inorganic flame retardant is minimized in the mechanical properties by minimizing the polarity difference with the matrix resin composed of polypropylene through the polysiloxane compound The present invention was completed by developing a polypropylene inorganic flame retardant composite resin composition having excellent tensile properties.

따라서, 본 발명은 인장특성이 우수한 폴리프로필렌계 무기난연제 복합수지 조성물을 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a polypropylene-based inorganic flame retardant composite resin composition having excellent tensile properties.

본 발명은 폴리프로필렌 수지 30 ~ 40 중량%와, 폴리실록산 화합물로 표면The present invention is 30 to 40% by weight of polypropylene resin, the surface of the polysiloxane compound

처리된 수산화 마그네슘 무기난연제 60 ~ 70 중량%를 포함하는 난연성 폴리프로필렌 수산화마그네슘 복합수지 조성물을 그 특징으로 한다.Characterized by a flame-retardant polypropylene magnesium hydroxide composite resin composition containing 60 to 70% by weight of the treated magnesium hydroxide inorganic flame retardant.

이와 같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.

본 발명은 폴리프로필렌 수지 30 ~ 40 중량%와 수산화 마그네슘 무기난연제 60 ~ 70 중량%로 배합함으로써 난연특성을 유지하면서 동시에 기계적 특성 중 인장특성이 매우 우수하여 전선재료 및 자동차 부품, 산업용 부품 등에 사용될 수 있는 난연성 폴리프로필렌 복합수지 조성물에 관한 것이다.The present invention is blended with 30 to 40% by weight of polypropylene resin and 60 to 70% by weight of magnesium hydroxide inorganic flame retardant while maintaining flame retardant properties and at the same time excellent in tensile properties among mechanical properties can be used in wire materials, automotive parts, industrial parts, etc. The present invention relates to a flame retardant polypropylene composite resin composition.

폴리프로필렌 수지가 사용되며, 이것은 용융지수(MI)가 0.5 ~ 3.0 g/10분(ASTM D1238, 230 ℃)이고 프로필렌 단독 중합체 혹은 랜덤, 블록 공중합체, 또는 그들의 혼합물이 사용될 수 있다. 이때, 용융지수가 0.5 g/10분(ASTM D1238, 230 ℃) 미만시에는 전선압출가공시 가공기기에 과도한 부하가 걸리는 문제가 있고, 3.0 g/10분(ASTM D1238, 230 ℃)를 초과시에는 장기내구성에 문제가 있어 바람직하지 못하다. 또한, 그 함량이 30 중량% 미만으로 적게 사용되면 수지 조성물의 비중이 증가하고, 인장강도, 인장신율, 충격강도 등의 기계적 물성이 나빠지 는 문제가 있으며, 40 중량% 초과시에는 난연성 저하 문제가 있다.Polypropylene resins are used, which have a melt index (MI) of 0.5 to 3.0 g / 10 min (ASTM D1238, 230 ° C.) and propylene homopolymers or random, block copolymers, or mixtures thereof may be used. At this time, if the melt index is less than 0.5 g / 10 minutes (ASTM D1238, 230 ℃), there is a problem that excessive load is applied to the processing equipment during wire extrusion processing, when it exceeds 3.0 g / 10 minutes (ASTM D1238, 230 ℃) There is a problem in organ durability, which is undesirable. In addition, when the content is used less than 30% by weight, the specific gravity of the resin composition increases, there is a problem that the mechanical properties such as tensile strength, tensile elongation, impact strength worsens, when the content exceeds 40% by weight there is a problem of flame retardancy. .

본 발명에서 수산화 마그네슘 무기난연제는 화학식 Mg(OH)2의 무기입자로서 백색의 분말형태이며 폴리실록산 화합물로 표면처리된 것으로 표면처리된 입자표면은 비극성 성질을 나타낸다. 상기 수산화 마그네슘 무기난연제의 함량이 60 중량% 미만일 경우에는 난연성 저하 문제가 있으며, 70 중량% 초과시에는 추가적인 난연성의 증대가 이루어 지지 않으며 인장강도가 급격히 감소하며 성형성이 불안정한 현상이 발생하기 때문에 바람직하지 못하다. 상기 폴리실록산 화합물은 다음 화학식 1로 표시되는 화합물이 바람직하다.In the present invention, the magnesium hydroxide inorganic flame retardant is an inorganic particle of the general formula Mg (OH) 2 in the form of a white powder, surface-treated with a polysiloxane compound surface treated particle surface exhibits a non-polar property. If the content of the magnesium hydroxide inorganic flame retardant is less than 60% by weight, there is a problem of lowering the flame retardancy, when the content of more than 70% by weight does not increase the additional flame retardancy is not preferable because the rapid decrease in tensile strength and unstable formability occurs Can not do it. The polysiloxane compound is preferably a compound represented by the following formula (1).

R1-(Si-O)n-R2 R 1- (Si-O) n -R 2

상기 화학식 1에서, n은 100 보다 크고 200 보다 작은 정수이며, R1는 히드록시기(-OH), R2는 메틸기(-CH3) 또는 에틸기(-CH2CH3) 이다. In Formula 1 , n is Is greater than 100 integer smaller than 200, R 1 is a hydroxy group (-OH), R 2 is a methyl group (-CH 3) or ethyl (-CH 2 CH 3).

상기와 같은 조성으로 이루어진 폴리프로필렌 복합수지는 난연특성을 유지하면서 인장특성이 매우 우수하여 전선재료 및 자동차 부품, 산업용 부품 등에 사용될 수 있을 것으로 기대된다.Polypropylene composite resin having the composition described above is expected to be used in electric wire materials, automotive parts, industrial parts and the like because the tensile properties are very excellent while maintaining the flame retardant properties.
