본 발명은 자동차용 텐션로드 부시 조성물에 관한 것으로서, 경도를 높이기 위해 사용하는 카본의 양을 줄이고, 고경도용에 주로 사용하는 특수천연고무(HS 785)를 사용하여 쿠션 텐션로드 부시를 제조함으로써, 경도는 동일한 상태에서, 인장강도, 신율 및 이들의 변화율과 압축영구 줄음율 등의 물리적 특성을 향상시키며, 또한 내구력을 보완하여 차축이 노면으로부터 받는 진동이나 충격을 흡수할 수 있는 자동차용 텐션로드 부시 조성물에 관한 것이다.The present invention relates to a tension rod bush composition for automobiles, by reducing the amount of carbon used to increase the hardness, by producing a cushion tension rod bush using a special natural rubber (HS 785) mainly used for high hardness, In the same state, the tension rod bush composition for automobiles that can improve the physical properties such as tensile strength, elongation and their rate of change and compressive permanent reduction, and can also supplement the durability to absorb the vibration or shock received from the axle road surface It is about.

일반적으로, 자동차에는 차축과 차체를 연결하여 주행중에 차축이 노면으로부터 받는 진동이나 충격을 차체에 직접 전달하지 않도록 하여, 차체와 화물의 손상을 방지하고 승차감을 좋게 하는 현가장치가 구비되어 있다.BACKGROUND ART In general, a vehicle is provided with a suspension device that connects the axle and the body so as not to directly transmit vibrations or shocks received from the road surface to the body while driving, thereby preventing damage to the body and cargo and improving ride comfort.

자동차 현가장치의 텐션로드는 I-암을 사용하는 서스펜션으로서 I-암 선단과 액슬 앞쪽의 바디 프레임을 연결하고, 휠에 가해지는 전·후 방향의 힘을 지지하는 것으로, 이러한 텐션로드의 일반적인 형상을 도 1를 참조하여 설명하면 다음과 같다.The tension rod of the vehicle suspension is an I-arm suspension that connects the I-arm tip and the body frame in front of the axle, and supports the front and rear forces applied to the wheel. Referring to Figure 1 as follows.

도 1에 도시된 바와 같이, 상기 텐션로드는 가늘고 긴 부재로 이루어진 로드 몸체(200)가 바디 프레임(300)에 연결되도록 되어 있고, 타측은 I-암(미도시)에 체결되어 있다.As shown in FIG. 1, the tension rod is configured such that a rod body 200 made of an elongated member is connected to the body frame 300, and the other side thereof is fastened to an I-arm (not shown).

상기 텐션로드 몸체(200)에는 와셔(400)와 텐션로드 부시(100)를 끼운후 바디 프레임(300)의 홀에 삽입한 후 역순으로 텐션로드 부시(100)와 와셔(400)를 각각 끼워 너트(500)로써 체결되도록 되어 있다.The washer 400 and the tension rod bush 100 are inserted into the tension rod body 200 and then inserted into the holes of the body frame 300. Then, the tension rod bush 100 and the washer 400 are inserted in the reverse order. It is intended to be fastened with 500.

종래의 텐션로드 부시(100)는 현재 내구 규격을 만족하지 못하여 북미 수출에 차질이 빚어지고 있는바, 내구력 저하에 따른 소음 및 클레임에 대응할 수 있는 텐션로드 부시가 요구된다.Conventional tension rod bush 100 does not satisfy the current durability standards, causing a bark to export to North America, the tension rod bush that can respond to noise and claims due to the durability is required.

따라서, 본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로서, 경도를 높이기 위해 사용하는 카본의 양을 줄이고, 고경도용에 주로 사용하는 특수천연고무(HS 785)를 사용하여 쿠션 텐션로드 부시를 제조함으로써, 경도는 동일한 상태인 HS80 상태에서, 인장강도, 신율 및 이들의 변화율과 압축영구 줄음율 등의 물리적 특성을 향상시키며, 또한 내구력을 보완하여 차축이 노면으로부터 받는 진동이나충격을 흡수할 수 있는 자동차용 텐션로드 부시 조성물을 제공하는데 그 안출의 목적이 있다.Therefore, the present invention has been made in view of the above problems, to reduce the amount of carbon used to increase the hardness, to manufacture a cushion tension rod bush using a special natural rubber (HS 785) mainly used for high hardness This improves the physical properties such as tensile strength, elongation, and the rate of change and compressive permanent reduction in the HS80 state, in which the hardness is the same, and also supplements the durability to absorb vibrations or shocks received from the axle from the road surface. It is an object of the present invention to provide a tension rod bush composition for automobiles.

본 발명은 경도가 HS80 정도인 고경도 제품으로 경도를 높이기 위해 사용하는 카본의 양을 줄이고, 고경도용에 주로 사용하는 특수천연고무(HS785)를 사용하여 경도를 높이는 효과를 얻고, 내구성을 향상시키는 발명인 것이다.The present invention is to reduce the amount of carbon used to increase the hardness to a high hardness product of about HS80 hardness, using the special natural rubber (HS785) mainly used for high hardness to obtain the effect of increasing the hardness, improving the durability It is an invention.

본 발명의 텐션로드 부시에는 고경도용 특수천연고무(HS785)를 일반 천연고무와 함께 사용한바, 상기 고경도 천연고무는 일본의 NIPOL사 제품으로서, 경도 뿐만 아니라 내구성을 향상시킨다. 사용량은 17-18phr 정도가 적당하다.In the tension rod bush of the present invention, a high hardness special natural rubber (HS785) is used together with general natural rubber. The high hardness natural rubber is manufactured by NIPOL of Japan, and improves hardness as well as durability. The usage amount is about 17-18phr.

카본 블랙인 SRF의 양은 약 17% 정도 줄여 사용한다. 이유는 특수천연고무인 HS785를 사용하였으므로 상대적으로 양을 줄여 목표 경도인 HS80에 맞출 수 있다.사용량은 57-58정도가 적당하다.Reduce the amount of SRF, carbon black, by about 17%. The reason is that special natural rubber HS785 is used, so that the amount can be relatively reduced to meet the target hardness of HS80.

제 1산화제인 Stearic acid는 1.3-1.5phr 정도가 적당하며, 제 2산화제인 Z3-Stearic acid는 탈거 용이를 위해 사용하나, 본 발명에서는 가공성 향상을 위해 비교예 대비 50%정도 추가한다. 상기 제 2산화제는 미국의 UNIROYAL CHEMICAL사 제품을 사용한다.Stearic acid as the first oxidizing agent is suitable about 1.3-1.5phr, Z3-Stearic acid as the second oxidizing agent is used for easy removal, but the present invention adds about 50% compared to the comparative example to improve processability. The second oxidizing agent uses a product of UNIROYAL CHEMICAL of USA.

내열노화방지제인 RD는 1.2 phr 정도 사용한다.RD, a heat-resistant anti-aging agent, is used at about 1.2 phr.

오존방지제인 3C는 1.2phr 정도 사용하는바, 내열, 내굴곡성 및 내산화성도 우수하다.The ozone inhibitor 3C uses about 1.2phr, which is excellent in heat, flex resistance and oxidation resistance.

황은 1.4-1.5phr 정도를 사용하는데, 1.4phr 이하이면 상온 내구력이 저하되고, 1.5phr 이상이면 내열성이 저하되는 문제점이 있다.Sulfur uses about 1.4-1.5 phr, but if it is 1.4 phr or less, room temperature durability is lowered, and if it is 1.5 phr or more, heat resistance is deteriorated.

가황촉진제는 티아졸계의 DM(MBTS, Dibenzeothiazyl Disulfide), CZ(CBS, N-Cyclohexyl-2-benzothiazyl sulfenamide), M(MBT, 2-Mercaptobenzeothiazyle)을 각각 0.6, 0.3, 0.2phr 정도 사용하여 가류를 안정화시키며 촉진하는 역할을 한다.Vulcanization accelerator stabilizes vulcanization by using thiazole DM (MBTS, Dibenzeothiazyl Disulfide), CZ (CBS, N-Cyclohexyl-2-benzothiazyl sulfenamide) and M (MBT, 2-Mercaptobenzeothiazyle) of 0.6, 0.3, and 0.2 phr, respectively. And promotes it.

점착부여제인 구마롱수지는 2.3-2.5phr을 사용하여 접착력을 향상시킨다.Kumarong resin, a tackifier, improves adhesion by using 2.3-2.5phr.

특히, 내약품성에 우수하다.In particular, it is excellent in chemical resistance.
