Description
본 발명은 부시(Bush) 고무 조성물에 관한 것으로서, 더욱 상세하게는 통상의 부시 고무 조성에 불소수지 분말을 첨가하여 이루어짐으로써 마찰력을 저감시킬 수 있는 부시 고무 조성물에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bush rubber composition, and more particularly, to a bush rubber composition capable of reducing frictional force by adding a fluororesin powder to a conventional bush rubber composition.
자동차용 부시의 고무 성분은 통상 마찰력이 커서 소음이 나는 요철부분을 지날때나 고속 주행시 문제가 생긴다.The rubber component of the automotive bush usually has a high frictional force and causes problems when passing through the uneven portion of noise or when driving at high speed.
종래의 부시 고무 조성물은 천연고무에 스테아린산, 산화아연, 카본블랙, 올레인산 아미드, 황, 촉매제 및 노후방지제를 첨가하여 제조된다.Conventional bush rubber compositions are prepared by adding stearic acid, zinc oxide, carbon black, oleic acid amide, sulfur, catalysts and anti-aging agents to natural rubber.
종래의 조성물은 올레인산 이미드를 배합물에 넣어 그의 표면에 배어나오는 기법을 사용하고 있으나, 그 효과가 1년 정도 밖에 유지되지 않는 문제가 있다.Conventional compositions use a technique in which the oleic acid imide is put in the formulation and soaked on the surface thereof, but the effect is maintained for about one year.
그리고, 상기와 같은 조성의 부시 고무 조성물은 상기한 고속 주행시의 소음의 문제를 해결할 수 없다.And the bush rubber composition of the above composition cannot solve the problem of the noise at the time of high speed running.
따라서, 본 발명의 부시 고무의 마찰력을 저감시키기 위해 불소수지를 분말상으로 첨가함으로써 본 발명을 완성하였다.Therefore, in order to reduce the frictional force of the bush rubber of this invention, this invention was completed by adding a fluororesin in powder form.
본 발명은 마찰력을 저감시킬 수 있는 부시 고무 조성물을 제공하는 데 그 목적이 있다.An object of the present invention is to provide a bush rubber composition that can reduce the friction force.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 천연고무, 촉진제 및 기타 첨가제로 이루어진 부시 고무 조성물에 있어서, 여기에 오일 전처리한 불소수지 분말을 수지성분 100 중량부에 대하여 5~20 중량부를 첨가하여 이루어진 것을 그 특징으로 한다.The present invention is characterized in that in the bush rubber composition composed of natural rubber, accelerator and other additives, the oil pretreated fluororesin powder is added by 5 to 20 parts by weight based on 100 parts by weight of the resin component.
이와같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.
본 발명은 불소수지 분말을 첨가하여 마찰력을 저감시킨 부시 고무 조성물에 관한 것으로서, 불소수지는 원래 내열성이 강하고 표면장력이 작아 자기윤활성이 있어 접착에 문제가 있다.The present invention relates to a bush rubber composition in which the friction force is reduced by adding fluororesin powder, and the fluorine resin has a high heat resistance and a small surface tension, and thus has a self-lubricating property, thereby causing adhesion problems.
그러나, 본 발명에서는 이와같은 불소수지의 자기윤활성의 문제를 해결하고자 그 분말을 이용하여 오일에 선 전처리를 한다. 이때, 오일은 수지 성분 100 중량부에 대하여 5~10 중량부 첨가한다.However, in the present invention, in order to solve the problem of self-lubrication of the fluororesin, the oil is pre-treated with the powder. At this time, 5-10 weight part of oil is added with respect to 100 weight part of resin components.
이와같은 처리를 거친 불소수지는 그 마찰력이 원수지에 비하여 양호하다.The fluorine resin, which has undergone such treatment, has better frictional force than that of the raw resin.
불소수지 분말은 천연고무 또는 부타디엔 고무의 함량 100 중량부에 대하여 5~20 중량부로서 그 함량이 상기 범위를 벗어나면 첨가효과가 미미하거나 비경제적인 문제가 있다.The fluororesin powder is 5 to 20 parts by weight based on 100 parts by weight of the natural rubber or butadiene rubber, and if the content is out of the above range, the effect of addition is insignificant or uneconomical.
불소수지 분말을 부시 고무 조성물에 첨가하는 경우 자체가 고무 배합물에 존재하고, 그 여분은 표면에 존재하기 때문에 차량 수명이 다할 때까지 고무가 노화된 후에도 수지에 의한 마찰력 저감효과가 유효하다.When the fluororesin powder is added to the bush rubber composition, since it is present in the rubber compound and the excess is present on the surface, the effect of reducing the frictional force by the resin is effective even after the rubber is aged until the end of the vehicle life.
또한, 반발탄성이 뛰어나고 마찰력이 적은 부타디엔 고무를 20~30 중량% 첨가하는 것이 천연고무만을 첨가한 것 보다는 마찰력이 낮아지고 내구력도 향상된다.In addition, the addition of 20 to 30% by weight of butadiene rubber having excellent resilience and low frictional force lowers frictional force and improves durability than natural rubber alone.
그 밖에 본 발명에서는 종래와 동일한 조성의 첨가제들을 함유하는 바, 그 함량은 통상의 부시 고무 조성물에서와 동일하다.In addition, the present invention contains additives of the same composition as in the prior art, the content of which is the same as in a conventional bush rubber composition.
상기와 같은 조성으로 이루어진 본 발명의 부시 고무 조성물은 내구성이 우수하고 자기 윤활성이 향상됨으로써 수명이 길어지므로 경제적인 측면에서 잇점을 줄 수 있고, 사용시 소음을 방지할 수 있다.Bush rubber composition of the present invention made of the composition as described above is excellent in durability and self-lubricating properties can be extended because of the long life can be an advantage in terms of economic, it can prevent noise in use.
이하, 본 발명을 실시예에 의거하여 상세히 설명하면 다음과 같은 바, 본 발명이 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to the following Examples, but the present invention is not limited by the Examples.
[실시예 1~5 및 비교예 1~2][Examples 1-5 and Comparative Examples 1-2]
