Description

용융 장력 및 가열 성형성이 우수한 폴리프로필렌 수지 조성물{POLYPROPYLENE COMPOSITION HAVING EXCELLENT MELT STRENGTH AND THERMOFORMING PROPERTY}Polypropylene resin composition excellent in melt tension and heat formability {POLYPROPYLENE COMPOSITION HAVING EXCELLENT MELT STRENGTH AND THERMOFORMING PROPERTY}

본 발명은 베타결정 폴리프로필렌 수지 조성물에 관한 것으로서, 더욱 상세하게는 고입체 규칙성의 폴리프로필렌 수지에 베타결정의 형성을 유도하는 핵제를 첨가함으로써 용융 장력 및 가열 성형성이 향상되고, 충격 강도 또한 우수한 폴리프로필렌 수지 조성물에 관한 것이다.The present invention relates to a beta-crystalline polypropylene resin composition, and more particularly, by adding a nucleating agent that induces beta crystal formation to a high-stereoregular polypropylene resin, melt tension and heat formability are improved, and impact strength is also excellent. It relates to a polypropylene resin composition.

일반적으로 폴리프로필렌은 다른 수지에 비해 상대적으로 높은 강도와 우수한 기계적인 성질을 가진 범용 플라스틱이며, 이는 고분자 사슬의 분자구조와 결정성에 기인한다. 더욱이 프로필렌 단독중합체는 고온에서의 변형에 우수한 저항성을 지니며, 높은 인장강도, 표면강성을 지니고 있으며, 용도에 따라 에틸렌이나 부틸렌을 불규칙 혹은 블록 공중합한 프로필렌 공중합체는 충격강도가 증가된다. In general, polypropylene is a general-purpose plastic having a relatively high strength and excellent mechanical properties compared to other resins, due to the molecular structure and crystallinity of the polymer chain. Furthermore, propylene homopolymers have excellent resistance to deformation at high temperatures, have high tensile strength and surface stiffness, and propylene copolymers with irregular or block copolymerization of ethylene or butylene are increased in impact strength depending on the application.

반면에 폴리프로필렌은 선형 사슬구조에 기인한 약한 용융 장력으로 인하여 다른 플라스틱 재료에 비해 진공성형이나 중공성형의 경우에 있어서 쉬트나 프리폼의 가열도중 처짐현상이 심하여 만족할 만한 성형성을 얻지 못하는 문제점이 있다.On the other hand, polypropylene has a problem of failing to obtain satisfactory formability due to the weak melt tension due to the linear chain structure in the case of vacuum or blow molding, which is severely sagging during heating of sheets or preforms compared to other plastic materials. .

따라서 이를 극복하기 위하여 폴리프로필렌과 같은 폴리올레핀의 용융 장력을 증가시키기 위한 여러 가지 방법이 제시되고 있는바, 첫번째는 폴리올레핀에 긴 가지(long chain branch)를 도입하여, 가공공정에서 고분자사슬간의 인력을 감소시켜 이지 플로우(easy flow)특성을 부여하며, 성형공정(특히, 대형 블로우 등과 같은 치수안정성을 요하는 용도)에서는 긴 가지가 인접 사슬과의 물리적 가교를 통해 고탄성을 나타내게 하는 방법이다. 그러나 이러한 방법은 제조공정의 어려움에 따른 비용이 상승하는 문제점이 있다. 두번째로는, 동일배열 폴리프로필렌은 알파결정과 베타결정이 존재하는데, 베타결정은 알파결정에 비해 강도가 높고 스트레스에 강한 물성을 가지고 있으므로 고입체규칙성 폴리프로필렌을 급속하게 급냉시키거나, 기계적인 응력을 가하여 베타결정 폴리프로필렌을 제조하는 방법이 있다. 그러나, 이러한 방법 역시 베타결정을 형성할 경우, 베타결정이 불균일하게 형성되어 재현성이 떨어지는 문제점이 있다.Therefore, in order to overcome this, various methods for increasing the melt tension of polyolefins such as polypropylene have been proposed. First, the introduction of long chain branches into polyolefins reduces the attraction between the polymer chains in the processing process. Easy flow characteristics, and in the forming process (particularly, applications requiring dimensional stability such as large blow, etc.), long branches have high elasticity through physical crosslinking with adjacent chains. However, this method has a problem that the cost increases due to the difficulty of the manufacturing process. Secondly, coarse polypropylene has alpha and beta crystals. Because beta crystals have higher strength and stress-resistant properties than alpha crystals, rapid quenching or mechanical There is a method of producing beta crystalline polypropylene by applying stress. However, this method also has a problem in that when beta crystals are formed, beta crystals are formed unevenly and thus are not reproducible.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여, 폴리프로필렌 수지에 베타결정을 유도하는 핵제를 첨가하여 폴리프로필렌에 베타결정을 형성하므로써, 용융 장력을 증가시켜 진공성형, 중공성형, 열성형 등의 공정에 적용 가능한 폴리프로필렌 수지 조성물을 제공하는 것을 목적으로 한다.In order to solve the problems as described above, by adding a nucleating agent that induces beta crystals to the polypropylene resin to form beta crystals in the polypropylene, by increasing the melt tension, vacuum molding, blow molding, thermoforming, etc. It aims at providing the polypropylene resin composition applicable to a process.

본 발명의 폴리프로필렌 수지 조성물은 고입체규칙성 폴리프로필렌 수지와 베타결정을 유도하는 핵제를 포함하는 것을 특징으로 한다.The polypropylene resin composition of the present invention is characterized in that it comprises a high stereoregular polypropylene resin and a nucleating agent for inducing beta crystals.

본 발명에서 사용되는 상기 폴리프로필렌 수지는 겔투과크로마토그래피(GPC)에 의해 측정된 분자량분포가 12 이상이고, 핵자기공명법상의 입체규칙도 지수가 펜타아드법 기준으로 96% 이상인, 분자량 분포가 넓은 고입체규칙성 폴리프로필렌 단독 중합체로서, 용융 지수는 1~6g/10분인 것이 바람직하다.The polypropylene resin used in the present invention has a molecular weight distribution of 12 or more, measured by gel permeation chromatography (GPC), and has a molecular weight distribution having a stereoregularity index of 96% or more based on the pentaad method. As a wide high-stereoregular polypropylene homopolymer, the melt index is preferably 1 to 6 g / 10 minutes.

상기 폴리프로필렌 수지의 분자량 분포가 12미만이거나 입체규칙도 지수가 펜타아드법 기준으로 96% 미만이면 폴리프로필렌 수지의 내열성, 표면강도 및 강도가 낮아지게 된다. When the molecular weight distribution of the polypropylene resin is less than 12 or the stereoregularity index is less than 96% based on the Pentaad method, the heat resistance, surface strength, and strength of the polypropylene resin are lowered.

또한, 상기 폴리프로필렌 수지의 용융지수가 1g/10분 미만이면 가공성이 양호하지 못하여 생산성이 떨어지고, 6g/10분을 초과하면 충격강도가 저하되므로 바람직하지 않다.In addition, if the melt index of the polypropylene resin is less than 1g / 10 minutes, the workability is not good, productivity is lowered, if it exceeds 6g / 10 minutes, the impact strength is lowered is not preferable.

본 발명에서 사용되는 핵제는 베타결정을 유도하기 위해서 사용되며, 구체적인 예로는 감마-퀴나크리돈, 퀴나크리돈 퀴논, 칼슘카보네이트, 칼슘스테아레이트와 디애시드의 혼합물(예로서, 피멜릭 애시드) 및 디사이클로헥실-2,6-나프탈렌 디카르복시 아미드 등이 사용될 수 있다.  Nucleating agents used in the present invention are used to induce beta crystals, specific examples are gamma-quinacridone, quinacridone quinone, calcium carbonate, a mixture of calcium stearate and diacid (e.g. pimelic acid) and Dicyclohexyl-2,6-naphthalene dicarboxy amide and the like can be used.

상기 핵제의 사용량은 상기 폴리프로필렌 수지 100중량부에 대하여 0.03~0.5중량부인 것이 바람직하며, 0.03중량부 미만인 경우에는 충분한 베타결정 폴리프로필렌을 얻기 어렵고, 0.5중량부를 초과하는 경우에는 더 이상의 물성 향상 효과가 발현되지 않는다.It is preferable that the usage-amount of the said nucleating agent is 0.03-0.5 weight part with respect to 100 weight part of said polypropylene resins, and when it is less than 0.03 weight part, sufficient beta crystal polypropylene will be difficult to obtain, and when it exceeds 0.5 weight part, further physical property improvement effect will be carried out. Is not expressed.

상기와 같은 본 발명의 폴리프로필렌 수지 조성물은 베타결정으로 존재하므로 알파결정에 비해 강도가 높고 스트레스에 강한 물성을 가지고 있다. 또한, 알파 결정 폴리프로필렌은 165~170℃에서 용융되나, 본 발명의 베타결정 폴리프로필렌은 용융 온도를 150~155℃ 정도로 낮출 수 있다. 이로 인해 본 발명의 폴리프로필렌 수지 조성물은 가공 공정에서 더 낮은 온도로 가열 성형을 할 수 있고, 또한 넓은 온도 범위에서 가공성을 조절할 수 있다.The polypropylene resin composition of the present invention as described above is present as a beta crystal has a higher strength than the alpha crystal and has a strong physical property against stress. In addition, the alpha crystalline polypropylene is melted at 165 ~ 170 ℃, the beta crystalline polypropylene of the present invention can lower the melting temperature to about 150 ~ 155 ℃. For this reason, the polypropylene resin composition of this invention can be heat-molded at lower temperature in a processing process, and can control workability in a wide temperature range.

본 발명의 폴리프로필렌 수지 조성물에는, 산화방지제, 내열안정제, 슬립제, 중화제와 같은 통상의 폴리프로필렌 수지 조성물에 첨가되는 각종 첨가제를 본 발명의 특징에 어긋나지 않는 범위 내에서 첨가할 수 있다.To the polypropylene resin composition of the present invention, various additives added to conventional polypropylene resin compositions such as antioxidants, heat stabilizers, slip agents, and neutralizing agents can be added within a range not departing from the characteristics of the present invention.

본 발명의 폴리프로필렌 수지 조성물을 제조하는 방법에 있어서는 특별한 제한이 없고, 당업자에게 알려진 폴리프로필렌 수지 조성물의 제조방법을 이용할 수 있다. 즉, 폴리프로필렌, 핵제 및 각 첨가제 성분들을 원하는 순서에 따라 자유롭게 선택하여 니더(kneader), 롤(Roll), 밤바리 믹서 등의 혼련기와 탠덤 압출기, 1축 또는 2축 압출기 등을 사용하여 혼련함으로써 본 발명의 수지 조성물을 제조할 수 있다.There is no restriction | limiting in particular in the method of manufacturing the polypropylene resin composition of this invention, The manufacturing method of the polypropylene resin composition known to those skilled in the art can be used.
