자동차에 사용되는 방진고무, 즉 엔진마운트(engine mount insulator)류와 부쉬(bush insulator)로 구분되며, 주로 엔진의 지지 및 진동절연 등을 목적으로 자동차에서는 중요한 기능부품으로 많은 연구가 진행되어 왔다.It is divided into anti-vibration rubbers used in automobiles, namely engine mount insulators and bush insulators, and many studies have been conducted as important functional parts in automobiles mainly for engine support and vibration isolation.
방진고무는 형상설계, 재료설계 및 평가기준에 의하여 용도 및 기능이 좌우되는 부품으로 주요소재가 고무재료로서 많은 한계를 가지고 있다.Anti-vibration rubber is a part whose use and function depend on the shape design, material design and evaluation criteria. The main material has many limitations as a rubber material.
특히, 방진고무에 사용되는 고무는 천연고무를 주원료로 사용하며 점탄성 및 가공성을 부여하기 위하여 충진제와 첨가제를 사용하여 지지 및 방진의 기능을 부여하고 있다. 방진고무의 취약점은 변위-하중에 따른 내피로도와 주변환경에 장시간 노출되어 사용되기 때문에 노화에 의한 내구력 및 특성의 저하문제는 계속적인 연구대상이다.In particular, the rubber used for the anti-vibration rubber uses natural rubber as the main raw material, and has a function of supporting and anti-vibration by using fillers and additives to impart viscoelasticity and processability. Since the weakness of the anti-vibration rubber is used for a long time due to the fatigue fatigue and the surrounding environment due to the displacement-load, the deterioration of durability and characteristics due to aging is a subject of continuous research.
방진고무는 진동절연과 내구력을 동시에 만족시켜야 하는 상반되는 특성을 고려해야 하는 단점을 갖고 있는데, 예로서 내구력을 개선하면 동배율 특히 동스프링 상수가 높아지는 문제로 진동절연성이 저하되며 반대로 동배율(동스프링 특성)을 개선하면 내구력이 저하되어 실용성이 결여되는 상반된 특성이 있다.Anti-vibration rubber has the disadvantage of considering the opposing characteristics of satisfying vibration insulation and durability at the same time. For example, if the durability is improved, the vibration insulation is deteriorated due to the problem of higher dynamic magnification, especially the dynamic spring constant. Properties), the durability is lowered, there is an opposite property that the practicality lacks.
따라서, 방진고무 분야에서 동배율(동스프링 특성) 저하와 내열성 개선 및 내구력을 동시에 만족시키는 과제가 특히 연구되어야 할 실정이다.Therefore, in the field of anti-vibration rubber, the problem of simultaneously satisfying the reduction of copper magnification (copper spring characteristics), heat resistance and durability is to be studied.
이에, 본 발명자들은 솔리드형 방진고무를 대상으로 종래기술의 문제점을 극복하고자 연구한 결과, 기존의 천연고무 대신 이소프렌 고무와 폴리부타디엔 고무를 일정 비율 사용하고, 황과 촉진제의 배율을 조정하고, 조촉진제로 TBTD을 사용함으로써 동특성 및 열에 대한 내열노화 피로도를 개선한 저동배율 및 내열내구력이 우수한 방진고무 조성을 개발함으로써 본 발명을 완성하였다.Therefore, the present inventors have studied to overcome the problems of the prior art for the solid-type anti-vibration rubber, using a certain ratio of isoprene rubber and polybutadiene rubber instead of the existing natural rubber, adjust the magnification of sulfur and accelerators, By using TBTD as an accelerator, the present invention was completed by developing a dustproof rubber composition having excellent low copper magnification and heat resistance, which improved dynamic characteristics and heat aging fatigue.
따라서. 본 발명은 동배율 및 내열내구력이 동시에 개선된 방진고무 조성물을 제공하고자 한다. therefore. The present invention is to provide a dustproof rubber composition with the same magnification and heat resistance improved at the same time.
본 발명은 폴리머 100 중량부, 필러 30 내지 45 중량부, 노화방지제 3 내지 7 중량부, 가류제 2 내지 5 중량부로 구성된 방진고무 조성물에 있어서, 상기 폴리머로 이소프렌 고무와 폴리부타디엔 고무의 중량비 70 내지 80 : 20 내지 30, 상기 가류제로 황과 촉진제의 중량비가 1 내지 1.5 : 0.5 내지 1로 이루어진 방진고무조성물을 그 특징으로 한다.The present invention provides a dustproof rubber composition composed of 100 parts by weight of polymer, 30 to 45 parts by weight of filler, 3 to 7 parts by weight of anti-aging agent, and 2 to 5 parts by weight of vulcanizing agent, wherein the polymer has a weight ratio of isoprene rubber and polybutadiene rubber of 70 to 70 parts by weight. 80: 20 to 30, wherein the vulcanizing agent is characterized in that the dust-proof rubber composition consisting of 1 to 1.5: 0.5 to 1 by weight ratio of sulfur and accelerator.
또한, 상기 촉진제는 테트라부틸티우람디설파이드(tetrabutylthiuram difulfide, TBTD)인 조성물을 포함한다.The accelerator also includes a composition that is tetrabutylthiuram difulfide (TBTD).
이와 같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.
본 발명은 폴리머, 필러, 노화방지제, 가류제 등으로 이루어진 방진고무 조성물에 있어서, 폴리머로 기존의 천연고무 대신 이소프렌 고무(IR)와 폴리부타디엔 고무(BR)를 일정 비율 사용하고, 가류제로 사용되는 황과 촉진제의 비율을 조정하고, 촉진제로 TBTD(tetrabutylthiuram disulfide)을 사용함으로써 동특성 및 열에 대한 내열노화 피로도를 개선한 방진고무 조성물에 관한 것이다.The present invention relates to a dustproof rubber composition comprising a polymer, a filler, an anti-aging agent, a vulcanizing agent, and the like, in which a predetermined ratio of isoprene rubber (IR) and polybutadiene rubber (BR) is used as a vulcanizing agent, instead of conventional natural rubber. The present invention relates to an anti-vibration rubber composition in which the ratio of sulfur and accelerators is adjusted, and TBTD (tetrabutylthiuram disulfide) is used as an accelerator to improve dynamic characteristics and heat aging fatigue resistance to heat.
폴리머는 기존에 천연고무 100 중량부를 사용한데 비해 본 발명에서는 이소프렌 고무(IR)와 폴리부타디엔 고무(BR) 폴리머 블렌드를 일정 비율 사용한다. IR : BR의 비율이 70 ∼ 80 : 20 ∼ 30(중량비)이 바람직하며, 상기 배합에서 IR을 기준으로 BR의 비율이 20% 미만이면 동스프링상수 저감율이 낮아지며, BR의 비율이 30% 초과하면 내구력 열세의 문제점이 있다. While the polymer is 100 parts by weight of natural rubber, the present invention uses a certain ratio of isoprene rubber (IR) and polybutadiene rubber (BR) polymer blend. When the ratio of IR: BR is 70 to 80:20 to 30 (weight ratio), the ratio of BR is less than 20% based on IR in the above formulation, and the reduction of the copper spring constant is lowered. There is a problem of poor durability.
한편, 필러로는 일반적으로 카본블랙, 산화아연, 산화마그네슘 등을 사용하는 것이 바람직하며, 이의 함량은 폴리머 100 중량부에 대하여 30 내지 45 중량부가 바람직하다. 이를 벗어나면 고무 물성의 저하로 정·동스프링상수 및 내구력 저하의 문제점이 있다.On the other hand, as the filler, it is generally preferred to use carbon black, zinc oxide, magnesium oxide, and the like, and the content thereof is preferably 30 to 45 parts by weight based on 100 parts by weight of the polymer. Departing from this, there is a problem of decreasing the static and copper spring constant and durability due to the deterioration of rubber properties.
또한, 노화방지제 역시 일반적으로 사용하는 페닐렌 디아민계(3C,KUMANOX13), 디하이드로퀴놀린계(RD), 왁스계(SUNNOC-N)등이 바람직하며, 이의 함량은 폴리머 100 중량부에 대하여 3 내지 7 중량부가 바람직하다. 이를 벗어나면 사용중 고무물성 및 작동조건에 관계없이 조기 파손의 문제점이 있다In addition, anti-aging agents are also generally used phenylene diamine (3C, KUMANOX13), dihydroquinoline (RD), wax (SUNNOC-N) and the like, the content thereof is 3 to 100 parts by weight of the polymer 7 parts by weight is preferred. Outside of this, there is a problem of premature failure regardless of the rubber properties and operating conditions during use.
또한, 가류제로서 유황(SULFUR)과 촉진제를 사용하는 유황과 촉진제의 비율이 1 ∼ 1.5 : 0.5 ∼ 1(중량비)이 바람직하며, 특히 촉진제인 TBTD(tetrabutylthiuram disulfide)의 사용으로 가황고무의 내열성이 향상되며 고무의 탄성력 보완으로 동스프링상수를 저감시키는 효과가 크다. 이때, 촉진제 비율이 0.5 미만이면 가류시간의 지연과 내열내구력이 낮아지며, 촉진제 비율이 1을 초과하면 상온내구력 낮아지며 동스프링상수 저감에 악영향을 미치는 문제점이 있다.In addition, the ratio of sulfur and accelerator using sulfur (SULFUR) and an accelerator as a vulcanizing agent is preferably 1 to 1.5: 0.5 to 1 (weight ratio), and particularly the heat resistance of the vulcanized rubber by using the tetrabutylthiuram disulfide (TBTD) as an accelerator. It is improved, and the effect of reducing the dynamic spring constant is large by supplementing the elastic force of rubber. At this time, if the accelerator ratio is less than 0.5, the delay of vulcanization time and heat resistance are low, and if the accelerator ratio is greater than 1, room temperature durability is low and there is a problem that adversely affects the reduction of the copper spring constant.
따라서, 본 발명은 폴리머로 기존의 천연고무 대신 이소프렌 고무와 폴리부타디엔 고무를 일정 비율 사용하고, 가류제인 황과 촉진제의 비율을 조정하고, 촉진제로 TBTD을 사용함으로써 동특성 및 열에 대한 내열노화 피로도를 개선한 저동배율 및 내열내구력이 우수한 방진고무 조성물로서, 자동차, 선박 분야 등에 유용하게 사용되어 질 것이다.Therefore, the present invention improves heat aging fatigue resistance to dynamic properties and heat by using a certain ratio of isoprene rubber and polybutadiene rubber as a polymer, adjusting the ratio of sulfur and accelerator as a vulcanizing agent, and using TBTD as accelerator. As a low vibration magnification and excellent heat resistance rubber composition, it will be usefully used in automobiles, ships, and the like.
이하, 본 발명은 시험예에 의거하여 더욱 상세하게 설명하겠는 바, 본 발명이 다음 실시예에 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail based on the test examples, but the present invention is not limited to the following examples.
시험예 Test Example
실시예 1 내지 2 및 비교예 1 내지 2은 엔진 및 샤시분야에서의 다음 표 1에 나타낸 조성으로 방진고무(INSULATOR)를 제조하여 다음과 같은 물성을 측정하였다.Examples 1 and 2 and Comparative Examples 1 and 2 were manufactured to the anti-dust rubber (INSULATOR) with the composition shown in Table 1 in the engine and chassis field to measure the following physical properties.
[물성평가방법][Property evaluation method]
1. 정스프링상수(Ks) 평가 1. Constant Spring Constant (Ks) Evaluation
기준 시험구간은 90 ±15 kgf 로 SAGINOMIYA社(일본)의 방진고무 특성시험기(1 TON) (방진고무용 특성시험기)를 사용하여 다음 수학식 1에 의해 측정하였다The standard test period was 90 ± 15 kgf and measured by SAGINOMIYA (Japan) dustproof rubber characteristic tester (1 TON) (dustproof rubber characteristic tester)
[수학식 1][Equation 1]
정스프링상수 (Ks) = 하중변화량(△kgf)/변위변화량(△ℓ(㎜))Positive spring constant (Ks) = Load change amount (△ kgf) / Displacement change amount (△ ℓ (mm))
2. 동스프링상수(Kd) 평가 2. Evaluation of Copper Spring Constant (Kd)
시험조건은 예비하중 90 kgf, 주파수 20 Hz, 진폭 ±0.5 mm 으로 SAGINOMIYA社(일본)의 방진고무 특성시험기(방진고무용 특성시험기)을 사용하여 측정하였다. 동스프링상수(Kd) 결과는 상기 시험조건에 의하여 장비에서 계산된다.The test conditions were measured using a SAGINOMIYA (Japan) anti-vibration rubber characteristic tester (anti-vibration rubber characteristic tester) at a preload of 90 kgf, frequency of 20 Hz, and amplitude of ± 0.5 mm. The dynamic spring constant (Kd) results are calculated in the instrument according to the test conditions.
3. 동배율 측정3. Dynamic magnification measurement
동배율은 다음 수학식 2에 의해 계산되어 지며, 동배율이 낮을수록 차량의 진동/소음의 개선 효과가 큰데, 정스프링상수는 차량의 고유특성으로 변화시킬 수 없으며, 동스프링상수를 낮추어야만 차량의 진동/소음 개선 효과가 크다.The dynamic magnification is calculated by the following Equation 2, and the lower the dynamic magnification, the greater the effect of improving the vibration / noise of the vehicle. The constant spring constant cannot be changed to the unique characteristics of the vehicle. Vibration / noise improvement effect is great.
[수학식 2][Equation 2]
동배율 = 동스프링상수(Kd)/정스프링상수(Ks)Dynamic magnification = Copper spring constant (Kd) / Constant spring constant (Ks)
4. 내구성능 평가 4. Durability Evaluation
1) 상온내구력 1) Room temperature durability
시험조건은 하중 120 ±240 kgf, 주파수 3.33㎐로 SAGINOMIYA社(일본)의 방진고무 내구시험기(3 TON)를 사용하여 고무부 크랙시까지 반복시험하였다.The test conditions were 120 ± 240 kgf and frequency 3.33 반복. The test was repeated until the rubber part cracked using a dustproof rubber endurance tester (3 TON) manufactured by SAGINOMIYA (Japan).
2) 내열내구력 2) heat resistance
SAGINOMIYA社(일본)의 방진고무 내구시험기(3 TON)을 사용하고, 부품에 환경 챔버(CHAMBER) 내(-50 ∼ +200 ℃)에서 예비하중 120 kgf를 가한 후 120 ℃에서 50시간 열노화시키고 부품을 실온(20 ℃)에서 1시간 이상 방치 후 하중 120 ±240 kgf, 주파수 : 3.33㎐의 조건으로 고무부 크랙시까지 반복시험하였다.Using SAGINOMIYA (Japan) anti-vibration rubber endurance tester (3 TON), the parts were subjected to a preload 120 kgf in a CHAMBER (-50 to +200 ℃), and then thermally aged at 120 ℃ for 50 hours. The parts were allowed to stand at room temperature (20 ° C.) for at least 1 hour and then repeatedly tested until the rubber part cracked under the conditions of 120 ± 240 kgf and frequency: 3.33 kHz.
상기 표 1에 나타낸 바와 같이, 비교예 1 및 2에 비해 실시예 1 및 2는 동배율을 결정하는 주요인자인 동스프링 상수 저감으로 실차 IDLE(600 rpm 이하 영역) 진동에서 2 내지 4 dB 이상의 개선 효과를 보이고, 상온내구력 및 내열내구력 또한 매우 향상됨을 확인할 수 있었다.As shown in Table 1, compared with Comparative Examples 1 and 2, Examples 1 and 2 are improved by more than 2 to 4 dB in the real vehicle IDLE (area below 600 rpm) by reducing the dynamic spring constant, which is the main factor for determining the dynamic magnification. The effect was shown, and room temperature durability and heat resistance were also found to be very improved.
따라서, 본 발명에 따른 방진고무 조성물은 폴리머로 기존의 천연고무 대신 이소프렌 고무와 폴리부타디엔 고무를 일정 비율 사용하고, 가류제인 황과 촉진제의 비율을 조정하고, 촉진제로 TBTD을 사용함으로써 동특성 및 내열내구력이 동시에 개선되어 자동차, 선박 등에 매우 유용하다.Therefore, the anti-vibration rubber composition according to the present invention uses a certain ratio of isoprene rubber and polybutadiene rubber instead of conventional natural rubber as a polymer, adjusts the ratio of sulfur and accelerator as a vulcanizing agent, and uses TBTD as an accelerator to provide dynamic characteristics and heat resistance durability. It is improved at the same time and is very useful for cars, ships and the like.
