Description
본 발명은 배터리 하우징 부품용 난연 폴리에스테르 조성물에 관한 것으로서, 더욱 상세하게는 폴리부틸렌테레프탈레이트 수지와 폴레에틸렌테레프탈레이트 수지를 기본 수지로 구성하고 여기에 에폭시계 브롬계 난연제 및 삼산화안티몬과 테프론계 및 실리콘계 난연보조제 및 유리섬유 충전재를 특정 비율로 혼합하여 구성함으로써, 성형품에 적용 시 후크크랙(hook crack), 인장강도, 난연성 및 광택성 등 제반 물성이 우수하게 개선되어 배터리 하우징 제조에 유용한 난연 폴리에스테르 조성물에 관한 것이다.
More particularly, the present invention relates to a flame retardant polyester composition for a battery housing component, and more particularly, to a flame retardant polyester composition for a battery housing component, which comprises a polybutylene terephthalate resin and a polyethylene terephthalate resin as base resins, And a silicone-based flame-retardant auxiliary agent and a glass fiber filler are mixed at a specific ratio. Thus, when applied to a molded product, various properties such as hook crack, tensile strength, flame retardancy and gloss are improved, Ester compositions.
종래에는 자동차 및 전지전자용 부품 소재의 재질로 변형 폴리페닐에테르 재질을 사용하였으나, 기존 변형 폴리페닐에테르 재질은 내열성도 약하고 난연특성이 부족하여 부품에서 발생되는 열에 의해 용융되거나 화재에 취약할 수가 있다.Conventionally, modified polyphenyl ether materials are used as materials for parts for automobiles and batteries. However, conventional modified polyphenyl ether materials have a poor heat resistance and lack flame retardant properties, which may be melted due to heat generated in the parts or may be vulnerable to fire .
일반적으로 자동차 및 전기전자용 부품 소재는 장기간 전기에 노출되는 부분으로 우수한 기계적 특성, 전기적 특성뿐만 아니라 높은 난연 특성이 요구되어 진다.Generally, automotive and electric parts are exposed to electricity for a long period of time and require high mechanical and electrical properties as well as high flame retardancy.
폴리에스테르 수지 조성물은 변형 폴리페닐에테르 수지 조성물에 비해 유연성이 다소 낮지만, 폴리에스테르 수지 조성물에 적정량의 유리섬유를 첨가하게 되면 기계적 특성이 향상되고 유연성도 확보할 수 있다.Although the polyester resin composition has a somewhat lower flexibility than the modified polyphenyl ether resin composition, when a proper amount of glass fiber is added to the polyester resin composition, the mechanical properties can be improved and the flexibility can be secured.
특히, 폴리에스테르 수지 조성물은 변형 폴리페닐에테르 수지 조성물에 비해 우수한 기계적 특성, 내열성과 난연성이 우수하여 제품 사용상에서 열에 의한 용융 또는 기계적 파손 및 화재를 방지할 수가 있어서 자동차용이나 전기전자 제품의 부품을 성형하는데 널리 사용되고 있다.Particularly, the polyester resin composition is excellent in mechanical properties, heat resistance and flame retardancy as compared with the modified polyphenyl ether resin composition, and can prevent melting or mechanical damage or fire due to heat in the use of the product, And is widely used for molding.
종래 기술로서, 한국특허공개 제2013-133746호에서는 폴리부틸렌 테레프탈레이트 수지 50-90중량%와, 폴리에틸렌 테레프탈레이트 수지 10-50중량%로 이루어진 수지성분에 100중량부 대해 인계 난연제 10-100중량부를 포함하는 밀착성과 난연성이 우수한 금속 복합 부품 성형용의 폴리부틸렌 테레프탈레이트 수지 조성물이 제안되어 있으며, 한국특허공개 제2014-110267호에서는 폴리부틸렌 테레프탈레이트 수지 35~90%, 브롬계 난연제 5~20%, 안티몬계 난연제 1~10%, 폴리플루오르에틸렌 수지 0.1~1.5%, 실리콘계 화합물 0.1~5% 및 무기필러 5~50%를 포함하는 것을 특징으로 하는 충격강도와 전기 절연성이 우수한 난연성 폴리부틸렌 테레프탈레이트 수지 조성물이 제안되어 있다.As a prior art, Korean Patent Laid-Open Publication No. 2013-133746 discloses a resin composition comprising 50-90 wt% of a polybutylene terephthalate resin and 10-50 wt% of a polyethylene terephthalate resin, and 100-100 wt parts of a phosphorus- A polybutylene terephthalate resin composition for molding a metal composite part having excellent adhesion and flame retardancy including a part of a polybutylene terephthalate resin is proposed. In Korean Patent Laid-Open Publication No. 2014-110267, 35 to 90% of a polybutylene terephthalate resin, To about 20%, an antimony flame retardant of 1 to 10%, a polyfluoroethylene resin of 0.1 to 1.5%, a silicone compound of 0.1 to 5% and an inorganic filler of 5 to 50%. A butylene terephthalate resin composition has been proposed.
이러한 종래기술에서는 폴리부틸렌테레프탈레이트 수지에 난연성을 부여하는 방법으로 할로겐계 난연제와 산화안티몬계 난연상승제 및 금속산화물 등의 조제를 사용하고 있으며, 특히 전기 및 전자 소자 등 난연성이 요구되는 분야에서는 브롬화 폴리카보네이트 올리고머, 브롬화 에폭시 올리고머 등의 난연제에, 삼산화 안티몬 같은 난연조제를 혼합한 조성물을 사용한다. 그러나 난연제의 비효율적 사용이나 과량 투입에 따라 수지 본래 특성의 충분한 발현이 어렵고, 가공상의 문제가 발생하는 문제가 있다. In this prior art, halogen flame retardants, antimony antimony flame retardants and metal oxides are used as additives for imparting flame retardancy to the polybutylene terephthalate resin. Particularly, in fields requiring flame resistance such as electric and electronic devices A brominated polycarbonate oligomer, a brominated epoxy oligomer and the like, and a flame retardant auxiliary such as antimony trioxide are mixed. However, inefficient use of the flame retardant or excessive introduction of the flame retardant makes it difficult to exhibit sufficient inherent characteristics of the resin, and there arises a problem that processing problems arise.
또한, 이러한 종래의 성형용 조성물은 물성 개선 측면에서 어느 정도 향상된 내용을 보이고 있으나, 인장강도와 광택성 등의 물성이 우수하면서도 난연성이 우수한 물성을 갖기에는 개선의 여지가 많았다.
Further, such conventional molding compositions exhibit some improvement in terms of improvement in physical properties, but there is much room for improvement in terms of excellent physical properties such as tensile strength and gloss and excellent flame retardancy.
본 발명은 상기와 같은 종래기술에서 문제로 지적되었던 난연성과 더불어서 후크크랙 특성과 인장강도 및 광택성이 모두 우수한 난연 폴리에스테르 조성물을 제공하는 것을 해결과제로 한다.The present invention provides a flame retardant polyester composition excellent in flame retardancy, hook cracking property, tensile strength and glossiness, which has been pointed out as a problem in the prior art.
따라서 본 발명의 목적은 인장강도와 함께 후크크랙 특성, 광택성 및 난연성이 모두 우수한 폴리에스테르 조성물을 제공하는데 있다.Accordingly, an object of the present invention is to provide a polyester composition which is excellent in tensile strength, hook cracking property, gloss and flame retardancy.
또한, 본 발명의 다른 목적은 후크크랙 특성이 개선되고 난연성과 광택성 등이 우수하여 배터리 하우징 부품용으로 유용한 물성을 가지는 난연 폴리에스테르 조성물을 제공하는데 있다.

실험예Experimental Example
하기 표 1의 조성에 따라 상기 실시에 및 비교예에서 제조된 난연 폴리에스테르 수지 조성물에 대하여 각각의 시험 시편을 제조하되 다음의 방법으로 준비하였다. Each test specimen was prepared for the flame retardant polyester resin composition prepared in the above Examples and Comparative Examples according to the composition shown in the following Table 1, and prepared by the following method.
상기 실시예 및 비교예의 각 수지 조성물은 25mm 이축압출기를 이용하여 250℃에서 혼련 후 시편 건조 후 100톤급 사출기를 통해 시편을 제작하였다. Each of the resin compositions of Examples and Comparative Examples was prepared by kneading at 250 ° C using a 25 mm twin-screw extruder, drying the specimen, and then extruding it through a 100-ton class extruder.
상기 제작된 시편에 대해 각각 다음과 같은 방법으로 물성을 측정하고 평가하여 하기 표 1에 비교하여 나타내었다.The properties of the prepared specimens were measured and evaluated in the following manner, respectively, and the results are shown in Table 1 below.
(1) 후크크랙(hook crack) 특성(1) Characteristics of hook crack
배터리 차단 유닛 제작 또는 사용 시 일정 수준 이상의 Hook crack 특성이 요구되므로 Dupont drop 기기를 통해 합격 여부(Pass/Fail)를 판단한다. Since the hook-cracking unit requires more than a certain level of hook cracking characteristics when manufacturing or using the battery cut-off unit, it is judged pass / fail through the Dupont drop device.
(2) 인장강도(2) Tensile strength
배터리 차단 유닛 사용 시 일정 수준 이상의 강도가 요구되므로 1000kgf/cm2 이상의 인강강도를 UTM 장비를 통해 측정한다. 인장강도가 1000kgf/cm2 미만인 경우는 품질 저하(불만족)로 판단한다.Since the battery cut-off unit requires a certain level of strength, the tensile strength of 1000 kgf / cm 2 or more is measured by UTM equipment. When the tensile strength is less than 1000 kgf / cm 2 , it is judged that the quality is low (unsatisfactory).
(3) 난연성(3) Flammability
배터리 차단 유닛 사용 시 발생되는 열에 의한 화재를 막기 위해 UL94 Spec.의 방법으로 난연성을 측정하였다. 자동차 및 전기 전자 부품 소재의 경우 난연성은 V-0 이상의 난연 특성을 요구한다. The flame retardancy was measured by the UL94 Spec. Method in order to prevent the fire caused by the heat generated when using the battery cutoff unit. In the case of automobile and electric and electronic parts, flame retardancy requires a flame retardancy of V-0 or higher.
(4) 광택도(4) Glossiness
육안 관찰을 통해 광택도를 평가하여 합격 유무를 판단한다. 이때 광택도는 10인의 패널이 배터리 차단 유닛 소재의 외관을 기준으로 광택도를 평가하고 최종 평가 결과에 대해 평균치를 기준으로 하여 합격 여부(Pass/Fail)를 결정하였다.
Evaluate the degree of gloss through visual observation and judge whether or not to pass. At this time, the gloss of the panel of 10 persons was evaluated based on the appearance of the battery cut-off unit material and the pass / fail was determined based on the average value of the final evaluation result.
