Description
본 발명은 자동차용 흡기 매니폴드의 소음저감을 위한 오버몰딩 조성물에 관한 것으로서, 더욱 상세하게는 디메틸테레프탈레이트, 1,4-부탄디올, 폴리프로필렌글리콜을 사용하여 종래 흡기 매니폴드에 오버몰딩하여 공기유입부의 두께를 늘림으로써, 공기유입시 소음이 차량내부에 전달되는 것을 방지하여 운전자의 운전환경이 향상된 자동차용 흡기 매니폴드의 소음저감을 위한 오버몰딩 조성물에 관한 것이다.The present invention relates to an overmolding composition for reducing noise of an intake manifold for automobiles, and more particularly, to inflow of air by overmolding a conventional intake manifold using dimethyl terephthalate, 1,4-butanediol, and polypropylene glycol. By increasing the thickness of the part, to prevent noise from being transmitted to the inside of the vehicle when the air inflow relates to an overmolding composition for reducing the noise of the intake manifold for automobiles in which the driver's driving environment is improved.
엔진 흡입 시스템에서 공기유입 및 조절 등의 역할을 하는 흡기 매니폴드의 재질이 플라스틱으로 적용되고 있으며, 이 플라스틱 재질은 공기유입시 소음이 차량내부에 전달되어 NVH(Noise & Vibration & Harnish)가 AL(Aluminium)사양보다 좋지 않은 것으로 알려지고 있다.The intake manifold, which plays a role in inlet and control of the engine intake system, is made of plastic, and the noise is transmitted to the inside of the vehicle when air inflows, so NVH (Noise & Vibration & Harnish) It is said to be worse than aluminum specifications.
특히 나일론66 재질의 소음문제는 재질특성상 저 rpm에서 투과음(transmission noise)이 존재함으로서 AL보다 전체적인 평균소음은 좋으나자동차의 소음특성상 저 rpm은 운전자의 가청구역에 있으므로 자동차 품질과 밀접한 관계를 이루고 있으며 해결을 해야할 숙제로 안고 있다. 이러한 문제점의 해결방법은 제품의 두께를 키우는 방법이 있으나 엔진부품의 레이아웃(layout)상 현실화하기 쉽지않고, 완벽한 소음제거(1 ∼ 1.5 dB; 오차범위)가 되지 않는다.In particular, the noise problem of nylon 66 is transmission noise at low rpm due to its material characteristics, so the overall average noise is better than AL. However, low rpm is closely related to the vehicle quality due to the noise characteristics of the car. I have a homework to solve. The solution to this problem is to increase the thickness of the product, but it is not easy to realize in terms of the layout of the engine parts, and does not achieve perfect noise reduction (1 to 1.5 dB; error range).
이에, 본 발명자들은 상기 문제점을 해결하기 위하여 연구 노력한 결과, 공기흡입시 소음발생이 보다 적은 새로운 자동차용 흡기 매니폴드의 소음저감을 위한 오버몰딩 조성물을 개발함으로써 본 발명을 완성하였다.Accordingly, the present inventors have completed the present invention by developing an overmolding composition for reducing the noise of a new intake manifold for automobiles with less noise during air intake as a result of research efforts.
따라서, 본 발명은 디메틸테레프탈레이트, 1,4-부탄디올, 폴리프로필렌글리콜을 사용하여 종래 흡기 매니폴드(intake manifold)에 오버몰딩(overmolding)하여 공기유입부(surge tank)의 두께를 늘림으로써, 공기유입시 소음이 차량내부에 전달되는 것을 방지하여 운전자의 운전환경이 향상된 자동차용 흡기 매니폴드의 소음저감을 위한 오버몰딩 조성물을 제공하는데 그 목적이 있다.Accordingly, the present invention increases the thickness of the air inlet by overmolding the conventional intake manifold using dimethyl terephthalate, 1,4-butanediol, and polypropylene glycol. It is an object of the present invention to provide an overmolding composition for reducing noise of an intake manifold for automobiles by preventing noise from being transmitted to the inside of the vehicle when the driver's driving environment is improved.
본 발명은 디메틸테레프탈레이트 30 ∼ 40 중량%, 1,4-부탄디올 20 ∼ 30 중량%, 폴리프로필렌글리콜 20 ∼ 30 중량%로 이루어진 오버몰딩 조성물을 그 특징으로 한다.The present invention is characterized by an overmolding composition consisting of 30 to 40% by weight of dimethyl terephthalate, 20 to 30% by weight of 1,4-butanediol, and 20 to 30% by weight of polypropylene glycol.
이와 같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.
본 발명에 사용하는 디메틸테레프탈레이트는 30 ∼ 40 중량% 함유하는 것이 바람직하며, 더욱 바람직하게는 40 중량% 함유하는 것이 좋다. 만일 그 함유량이 30 중량% 미만이면 소음효과가 떨어지는 문제가 있고, 40 중량% 보다 과량이면 사출시 문제가 있다.It is preferable to contain 30-40 weight% of dimethyl terephthalates used for this invention, More preferably, it is preferable to contain 40 weight%. If the content is less than 30% by weight, there is a problem that the noise effect is lowered, if the content is more than 40% by weight there is a problem in the injection.
1,4-부탄디올은 20 ∼ 30 중량% 함유하는 것이 바람직하며, 더욱 바람직하게는 30 중량% 함유하는 것이 좋다. 만일 20 중량% 미만이면 제조시 문제가 있고, 30 중량% 보다 과량이면 사출시 문제가 있다.It is preferable to contain 20-30 weight% of 1, 4- butanediol, More preferably, it is preferable to contain 30 weight%. If it is less than 20% by weight, there is a problem in manufacturing, and in excess of 30% by weight, there is a problem in injection.
폴리프로필렌글리콜은 20 ∼ 30 중량% 함유하는 것이 바람직하며, 더욱 바람직하게는 30 중량% 함유하는 것이 좋다. 만일 20 중량% 미만이면 소음효과가 미비하며, 30 중량% 보다 과량이면 제조시 문제가 있다.It is preferable to contain 20-30 weight% of polypropylene glycol, More preferably, it is preferable to contain 30 weight%. If it is less than 20% by weight, the noise effect is insignificant, and if it is more than 30% by weight, there is a problem in manufacturing.
본 발명에 따른 오버몰딩 조성물을 사용하여 기존 흡기 매니폴드 성형품의 두께를 늘리는 방법으로는 기존품의 공기유입부분의 형상을 금형제작하여 제품을 삽입사출하는 방법을 사용할 수 있다.As a method of increasing the thickness of an existing intake manifold molded product using the overmolding composition according to the present invention, a method of inserting and inserting a product by manufacturing a mold of an air inlet portion of the existing product may be used.
