Description
본 발명은 차체 플로어(Floor) 제진재용 고무시트에 관한 것으로서, 더욱 상세하게는 종래 베이스(Base), 충진제, 가공조제, 점착부여제의 조성및 함량을 개선시키고 추가적으로 경화제와 첨가제를 포함하는 차체 플로어(Floor) 제진재용 고무시트에 관한 것이다.The present invention relates to a rubber sheet for a vehicle vibration damper, and more particularly, to improve the composition and content of a base, a filler, a processing aid, a tackifier, and additionally include a hardener and an additive. (Floor) The present invention relates to a rubber sheet for vibration damper.
일반적으로 현재 중·고급차종에 확산 적용되고 있는 차체 플로어용 제진재료는 아스팔트 시트만으로 이루어진 종래 제진재의 강성을 향상시키기 위해 1,2-폴리부타디엔을 기본 폴리머로하는 고무시트를 구속재로 아스팔트 시트위에 부착시킨 복합형 구조이다(도 1). 이러한 복합형 구조의 제진재료 시트는 기본 폴리머가 상온에 비하여 고온영역(40 ∼ 60℃)에서 우수한 댐핑(Damping)효과를 나타내어 주행시 온도상승으로 제진특성이 현저히 감소되는 단점을 보강하여 고온에서도 제진성이 우수하고 고무계열의 구속재가 경화되어 아주 단단한 시트로 되어 강성이 우수하게 되므로 강성이 요구되는 부위에 많이 사용되고 있다. 그러나 온도상승에 따라 제진성능이 우수하기는 하나, 20℃ 부근에서는 오히려 제진성능이 우수하지 않아 자동차가 온도상승되기 이전에는 제진성능이 매우 떨어지는 문제점이 있다. 또한 도장라인의 경화시 복합층 구조로 인하여 가스빼기 불량이 발생하면 부풀어 오르는 문제가 발생하고 구속층 재료가 고무 계열로 수분에 의한 취약성이 있어 일부 수분이 많으면 구속층 자체가 경화후 부풀어 오르는 문제점이 있다. 이 밖에도 경화시 미경화가 발생되면 정확한 제품이 되지 않고 상온에서 자연경화가 발생되어 황냄새가 발생하는등의 문제가 있어 이에 대한 개선의 필요성이 지대한 실정이었다. In general, the vibration damping material for body floors currently being applied to mid- and high-end cars is asphalt sheet with restraining rubber sheet based on 1,2-polybutadiene as the main polymer in order to improve the rigidity of the conventional vibration damping material consisting only of asphalt sheet. It is a composite structure attached to it (Fig. 1). The damping material sheet of the composite structure exhibits excellent damping effect in the high temperature range (40 to 60 ° C.) compared to the normal temperature, thereby reinforcing the disadvantage that the damping characteristic is significantly reduced due to the temperature rise during driving. This excellent, rubber-based restraint material is hardened and becomes a very hard sheet, so that the rigidity is excellent, it is widely used in the area where rigidity is required. However, although the vibration damping performance is excellent according to the temperature rise, the vibration damping performance is not very good at around 20 ° C., so the vibration damping performance is very poor before the temperature rise of the vehicle. In addition, due to the complex layer structure during the curing of the coating line, a problem of swelling occurs when there is a problem of bleeding gas, and the restraint layer material is vulnerable to moisture due to the rubber-based material. have. In addition, when the uncured hardening occurs during the curing, there is a problem such as a natural odor occurs at room temperature to produce a sulfur smell, so there is a great need for improvement.
이에, 본 발명자들은 상술한 바와 같이 저온에서의 제진성능을 개선시키기 위하여 예의 노력한 결과, 종래 베이스(Base) 폴리머, 충진제, 가공조제, 점착부여제의 조성및 함량을 개선시키고 추가적으로 경화제와 첨가제를 혼합 제조함으로서, 저온에서의 제진성능은 물론 강성율도 개선되고 비중도 낮출 수 있음을 확인하고 본 발명을 완성하게 되었다.Accordingly, the present inventors have made diligent efforts to improve the vibration damping performance at low temperatures as described above, and as a result, improve the composition and content of conventional base polymers, fillers, processing aids, tackifiers, and additionally mix hardeners and additives. By preparing, it was confirmed that the vibration suppression performance at low temperature as well as the stiffness can be improved and the specific gravity can be lowered, thus completing the present invention.
따라서, 본 발명은 베이스(Base) 폴리머, 충진제, 가공조제, 점착부여제의 조성및 함량을 달리하고 경화제와 첨가제를 추가적으로 포함하는 차체 플로어(Floor) 제진재용 고무시트를 제공하는데 그 목적이 있다. Accordingly, an object of the present invention is to provide a rubber sheet for vehicle floor vibration damper that includes a base polymer, a filler, a processing aid, and a tackifier, and further comprises a hardener and an additive.
본 발명은 베이스(Base) 폴리머, 충진제, 가공조제, 점착부여제로 이루어진 고무시트에 있어서, 메타크릴레이트(Methacrylate) 경화제 1 ∼ 4 중량%; 카본블랙(Carbon Black), 브라운 아스팔트(Blown asphalt) 중에서 선택된 첨가제 1 ∼ 5 중량%를 포함하는 차체 플로어(Floor) 제진재용 고무시트를 그 특징으로 한다.The present invention is a rubber sheet consisting of a base polymer, a filler, a processing aid, a tackifier, 1 to 4% by weight of a methacrylate (Methacrylate) curing agent; A rubber sheet for a vehicle floor vibration damper comprising 1 to 5% by weight of an additive selected from carbon black and brown asphalt.
이와 같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.
본 발명은 차체 플로어(Floor) 제진재용 고무시트에 관한 것으로서, 저온에서도 제진성능이 우수하고 강성율도 매우 높을 뿐만아니라, 비중도 낮게 개선된 것이다. The present invention relates to a rubber sheet for vehicle floor vibration damping materials, and has excellent vibration damping performance at low temperatures, a very high stiffness ratio, and a low specific gravity.
본 발명에 따른 제진재용 고무시트의 각 조성및 함량에 대하여 더욱 구체화하여 설명하면 다음과 같다.Hereinafter, the specific composition and content of the vibration damping rubber sheet according to the present invention will be described in detail.
먼저, 본 발명은 경화제및 첨가제를 새로이 첨가하는데 가장 큰 특징이 있는 바, 폴리아미드(Polyamide)계, 이미다졸(Imidazol) 변성 및 메타크릴레이트(Methacrylate)중에서 선택된 1종 이상을 전체 조성물 함량중 1 ∼ 4 중량%를 사용하는 것이 바람직하다. 왜냐하면 상기 범위를 벗어나면 접착력이 떨어져 하단부의 아스팔트 시트와의 부착력이 떨어지는 문제가 있기 때문이다. 그리고 첨가제는 내열성, 착색성, 보강성을 위해 첨가하는 것으로, 카본블랙(Carbon Black), 혼합 금속염(Mixed metal salts)또는 브라운 아스팔트(Blown asphalt)중에서 선택된 1종 이상을 전체 조성물 함량중 1 ∼ 5 중량%를 사용하는 것이 바람직하다. 만일 상기 범위를 벗어나면 제품의 착색및 내열성등에 같은 부작용이 발생하게 된다. First, the present invention is characterized by the greatest addition to the new addition of a curing agent and additive, at least one selected from polyamide-based, imidazol-modified and methacrylate 1 It is preferable to use 4 weight%. This is because the adhesive force is out of the above range and the adhesive force with the asphalt sheet of the lower end is falling. In addition, the additive is added for heat resistance, colorability, and reinforcement, and at least one selected from carbon black, mixed metal salts, and brown asphalt is 1 to 5% by weight of the total composition. Preference is given to using%. If outside the above range, the same side effects occur in the coloring and heat resistance of the product.
또한 본 발명은 종래 고무시트와는 달리 베이스(Base) 폴리머로서 1,2-폴리부타디엔이 아닌 폴리프로필렌에 EPDM가교화한 열가소성고무, 열가소성고무 (Thermoplastic rubber(TPR)) 변성 비닐아세테이트(Vinyl acetate), 수화 열가소성 일라스토머(Thermoplastic elastomer,TPE)또는 폴리메틸메타아크릴레이트(Poly Methyl Methacrylate)수지(PMMA resin)중에서 선택된 1종 이상을 전체 조성물 함량 중 25 ∼ 40 중량%를 포함한다. 왜냐하면 이들 함량이 25 중량% 미만이면 다른 조성과의 분산성이 저하되고 내충격성과 부착성 저하 및 박리문제가 발생되고, 40 중량%를 초과하면 강성유지및 제진성과 생산성 저하로 바람직하지 못하기 때문이다. 그리고 본 발명은 충진제를 포함하고 있으며, 이러한 충진제로는 마이카(Mica), 벤토나이트계, 산화철(Iron oxide)또는 탄산칼슘 중에서 선택된 1종 이상을 전체 조성물 함량중 30 ∼ 50 중량%를 포함하는것이 바람직하다. 왜냐햐면, 이들 함량이 전체 조성물 함량중 30 중량% 미만이면 제진성이 저하되며, 50중량%를 초과함유하면 다른 조성과의 혼합불량이 되어 요구물성을 얻을 수 없을 뿐만아니라 작업성도 저하되어 바람직하지 않기 때문이다. 또한 본 발명은 가공조제로서 전체 조성물 함량중 8 ∼ 23 중량%를 포함하며, 프탈레이트(Phthalate)계인 것을 사용한다. 이때 이 함량이 8 중량% 미만이면 가공성과 성형성이 불량이 되는데 반해, 23 중량%를 초과하면 목적하는 물성을 얻기 어려운 문제점이 있게된다. 이밖에도 유연성과 접착성 향상을 위해 점착부여제로서 폴리부타디엔 수지(Polybutadiene resin)를 전체 조성물 함량중 1 ∼ 3 중량%를 포함한다. 마지막으로 본 발명은 전체 조성물 함량중 8 ∼ 15 중량%의 에폭시 수지를 추가적으로 포함한다. 이러한 에폭시 수지로는 비스페놀 A계또는 합성고무계 에폭시 수지를 사용하는 것이 바람직하며, 이들 함량이 8 중량% 미만이면 접착력 저하와 기계적 강성저하를 가져오고, 15 중량%를 초과하면 내충격성이 저하되게 된다. 또한 조성구성에 따라서 사용하지 않아도 좋다.In addition, the present invention, unlike the conventional rubber sheet as a base (Base) polymer, 1,2-polybutadiene, EPDM cross-linked thermoplastic rubber, thermoplastic rubber (Tr) modified vinyl acetate (Vinyl acetate) At least one selected from hydrated thermoplastic elastomer (TPE) or polymethyl methacrylate resin (PMMA resin) includes 25 to 40 wt% of the total composition content. If these contents are less than 25% by weight, the dispersibility with other compositions is lowered, impact resistance and adhesion deterioration and peeling problems occur, and if the content exceeds 40% by weight, it is undesirable because of stiffness maintenance and vibration damping and productivity reduction. to be. In addition, the present invention includes a filler, and the filler may include 30-50 wt% of one or more selected from mica, bentonite, iron oxide, or calcium carbonate. Do. If the content is less than 30% by weight of the total composition content, the damping resistance is lowered. If the content is more than 50% by weight, it is not mixed with other compositions, and the required properties are not obtained. Because it does not. In addition, the present invention comprises 8 to 23% by weight of the total composition as a processing aid, and uses a phthalate (Phthalate) system. In this case, if the content is less than 8% by weight, the workability and moldability are poor, whereas if the content is more than 23% by weight, it is difficult to obtain the desired physical properties. In addition, the polybutadiene resin (Polybutadiene resin) contains 1 to 3% by weight of the total composition as a tackifier to improve flexibility and adhesion. Finally, the present invention further comprises 8 to 15% by weight of epoxy resin in the total composition content. It is preferable to use bisphenol A-based or synthetic rubber-based epoxy resins as such epoxy resins. If the content is less than 8% by weight, the adhesive strength and mechanical rigidity are lowered, and if the content exceeds 15% by weight, the impact resistance is lowered. . Moreover, it is not necessary to use it according to a composition structure.
이하, 본 발명을 다음의 실시예에 의거하여 더욱 상세히 설명하겠는 바, 본 발명이 실시예에 한정되는것은 아니다.Hereinafter, the present invention will be described in more detail based on the following examples, but the present invention is not limited to the examples.
