Description
본 발명은 자동차의 엔진 주변 부품중 전기장치 연결 시스템 부품인 퓨즈 박스의 커버용 수지 조성물에 관한 것이다.The present invention relates to a resin composition for a cover of a fuse box which is an electric device connection system part among engine peripheral parts of an automobile.
종래의 퓨즈 박스 커버는 주로 다량의 고무 성분이 함유된 나이론-66 수지로 제조해 왔기 때문에 내열온도가 낮아 엔진에서 발생되는 열 및 하절기 자연광에 의한 상승열로 인하여 퓨즈 박스 커버가 변형되거나 퓨즈 박스 커버에 내장된 퓨즈 박스 본체의 뒤틀림 우려가 높았다. 그 결과 퓨즈의 교체시에 퓨즈 박스 커버 전체를 교체해야 되는 문제점도 있다.Since the conventional fuse box cover has been mainly made of nylon-66 resin containing a large amount of rubber components, the fuse box cover may be deformed or the fuse box cover due to heat generated from the engine due to low heat resistance and rising heat caused by natural light in summer. There is a high risk of distortion of the fuse box body built into the. As a result, there is a problem that the entire fuse box cover must be replaced when the fuse is replaced.
이러한 문제를 해결하기 위해서는 내열성이 높아 온도 상승에 의한 변형이 없고, 탄성율이 우수하여 뒤틀림에 대한 저항력이 있고, 부품의 조립, 취출시에 요구되는 강도 및 자동차의 주행에 따른 내진동성을 갖는 자동차 퓨즈 박스 커버용 수지 조성물이 요구되어 왔다.In order to solve this problem, it has high heat resistance, no deformation due to temperature rise, excellent elastic modulus, resistance to warpage, strength required for assembly and take-out of parts, and vibration resistance according to driving of the car. There has been a demand for resin compositions for box covers.
이에 본 발명자는 상기 조건을 만족시킬 수 있는 퓨즈박스 커버용 수지로서 내충격성을 보강한 유리섬유강화 내충격성 폴리아미드가 가장 적합하다는 결론을 얻음으로써 본 발명은 완성하였다.The present inventors have completed the present invention by obtaining the conclusion that the glass fiber reinforced impact polyamide reinforced with impact resistance is most suitable as a resin for a fuse box cover capable of satisfying the above conditions.
이에 본 발명은 자동차의 퓨즈 박스 커버의 생산, 적용에 있어서 요구되는 충격특성, 강성 및 내열성 등의 각종 물성이 우수한 새로운 수지 조성물을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a new resin composition excellent in various physical properties such as impact characteristics, rigidity and heat resistance required in the production and application of a fuse box cover of an automobile.
본 발명은 내열성이 우수하여 온도상승에 따른 열변형을 방지할 수 있고, 강성, 내충격성 및 내진동성이 우수한 자동차 퓨즈 박스 커버용 수지 조성물을 제공하고자 한다.The present invention is to provide a resin composition for automotive fuse box cover excellent heat resistance can prevent thermal deformation due to temperature rise, excellent rigidity, impact resistance and vibration resistance.
본 발명은 자동차의 엔진 주변 부품중 전기장치 연결 시스템 부품인 퓨즈 박스의 커버용 수지 조성물에 관한 것이다.The present invention relates to a resin composition for a cover of a fuse box which is an electric device connection system part among engine peripheral parts of an automobile.
더욱 구체적으로 본 발명은 폴리아미드-66 수지를 주성분으로 하는 자동차 퓨즈 박스 커버용 수지 조성물에 있어서, 폴리아미드-66 수지 67∼89 중량 %, 내충격제로서 말레익산 무수물이 치환된 에틸렌-프로필렌-디엔모노머(EPDM) 고무 5∼15 중량%, 수지 강화제로서 유리섬유 5∼15 중량% 및 내열제/이형제/카본블랙의 혼합물 1∼3 중량%로 구성되어 열변형 온도가 190℃ 이상인 퓨즈 박스 커버용 수지 조성물에 관한 것이다.More specifically, the present invention relates to a resin composition for automobile fuse box cover containing polyamide-66 resin as a main component, 67 to 89% by weight of polyamide-66 resin, and ethylene-propylene-diene substituted with maleic anhydride as an impact agent. For fuse box covers with a thermal deformation temperature of 190 ° C or higher, consisting of 5 to 15% by weight of monomer (EPDM) rubber, 5 to 15% by weight of glass fiber as a resin reinforcement, and 1 to 3% by weight of a mixture of heat resistant agent / release agent / carbon black It relates to a resin composition.
이하, 본 발명을 더욱 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 수지 조성물에는 인장강도, 굴곡강도 및 열변형 온도의 향상을 위해 수지 강화제인 유리 섬유를 전체 수지 조성물 전체 중량 대비 5∼15 중량 % 첨가한다. 유리 섬유의 함량이 5 중량% 미만인 경우에는 수지 조성물의 인장강도와 굴곡 강도가 낮아지고, 유리 섬유의 함량이 15 중량%를 초과하는 경우에는 굴곡 강도가 1800Kg/㎠ 이상으로 너무 높아져 제품의 조립, 취출시 장부(Hinge)인 파손으로 재사용이 어려운 문제가 발생한다.In order to improve the tensile strength, flexural strength and heat deformation temperature, the glass composition, which is a resin reinforcing agent, is added to the resin composition of the present invention by 5 to 15% by weight based on the total weight of the total resin composition. When the glass fiber content is less than 5% by weight, the tensile strength and the flexural strength of the resin composition are lowered. When the glass fiber content is more than 15% by weight, the flexural strength is too high, such as 1800Kg / cm 2 or more, to assemble the product. When taking out, it is difficult to reuse because of damage to the book (Hinge).
이때 사용되는 유리 섬유의 직경은 10∼13㎛인 것이 바람직하다. 유리 섬유는 일반적인 압출 가공 공정에서 압출 스크류의 힘에 의해서 분해되어 제품상에는 거의 1mm 이하의 길이로 존재한다. 이들 유리 섬유는 수지 보강제의 역할과 동시에 무기핵제로서의 역할도 수행한다. 만약 유리 섬유의 직경이 10㎛ 미만인 경우에는 무기핵제 역할은 우수해지나 수지 보강 효과가 저하되고, 유리 섬유의 직경이 13㎛을 초과하는 경우에는 수지 보강 효과는 우수해지나 무기핵제 역할이 저하된다.It is preferable that the diameter of the glass fiber used at this time is 10-13 micrometers. Glass fibers are decomposed by the force of an extrusion screw in a general extrusion process and are present on the product in a length of almost 1 mm or less. These glass fibers play a role as an inorganic nucleating agent at the same time as the resin reinforcing agent. If the diameter of the glass fiber is less than 10㎛, the role of inorganic nucleating agent is excellent, but the resin reinforcing effect is reduced, if the diameter of the glass fiber exceeds 13㎛, the resin reinforcing effect is excellent but the role of inorganic nucleating agent is lowered .
본 발명에 사용되는 유리섬유는 더욱 바람직하기로는 아미노실린계로 표면처리된 유리 섬유를 사용하는 것이 좋다.As the glass fiber used in the present invention, it is more preferable to use the glass fiber surface-treated with aminosilin.
한편 본 발명의 수지 조성물에는 내충격성 향상을 위해 내충격제인 말레익산 무수물이 치환된 에틸렌-프로필렌-디엔모노머(EPDM) 고무를 수지 조성물 전체 중량 대비 5∼15 중량% 첨가한다. 내충격제의 첨가량이 상기 범위보다 낮을 경우에는 내충격성이 저하되며, 상기 범위를 초과할 경우에는 수지 조성물의 기계적 물성이 저하될 우려가 있다.On the other hand, the resin composition of the present invention is added 5 to 15% by weight of ethylene-propylene-diene monomer (EPDM) rubber substituted with maleic acid anhydride as an impact agent to improve impact resistance. When the addition amount of the impact resistant agent is lower than the above range, the impact resistance is lowered, and when it exceeds the above range, there is a fear that the mechanical properties of the resin composition are lowered.
본 발명에서 사용하는 내충격제에는 말레익산 무수물이 치환되어 있어서 주성분인 폴리아미드 66 수지와 내충격제간의 상용성을 향상시킬 수 있다.Maleic anhydride is substituted for the impact resistant agent used in the present invention, so that the compatibility between the main component polyamide 66 resin and the impact resistant agent can be improved.
한편 본 발명의 수지 조성물에는 내열제, 이형제 및/또는 카본블랙을 수지 조성물 전체 중량 대비 1∼3 중량% 첨가한다.On the other hand, to the resin composition of the present invention, a heat resistant agent, a releasing agent and / or carbon black is added in an amount of 1 to 3% by weight based on the total weight of the resin composition.
내열제로서는 이가녹스 B 1171 (시바-가이기사 제조)등이 사용되며, 이형제로서는 에틸렌 비스 스테아미드(페드로 케미칼사 제조)등이 사용되며, 카본 블랙은 카본블랙 마스터 뱃치 등의 형태로 사용된다.As heat-resistant agent, Iganox B 1171 (manufactured by Ciba-Geigy Co., Ltd.) and the like are used. As the release agent, ethylene bis steamide (manufactured by Pedro Chemical Co., Ltd.) and the like are used, and carbon black is used in the form of a carbon black master batch or the like.
