Description
본 발명은 아크릴 에멀젼(ACRYL EMULSION)을 주제로 한 자동차 패널의 실링 및 재진용 페이스트(PASTE) 상의 조성물로서 특히 자동차의 대쉬 패널(DASH PANEL), 프로어 패널(FLOOR PANEL), 사이드 패널(SIDE PANEL)등 구조적으로 평활하지 않은 부위에는 스프레이(SPRAY)에 의한 도포가 가능하여 우수한 적용성.The present invention is a composition on the sealing and resurfacing paste (PASTE) of the automotive panel based on the acrylic emulsion (ACRYL EMULSION), in particular, the dash panel (FLOOR PANEL), the side panel (SIDE PANEL) of the automobile It is possible to apply by spray on the parts that are not structurally smooth.
경화성, 접착성, 실링성, 및 제진성이 뛰어난 자동차 패널의 실링 및 제진용 페이스트상 조성물에 관한 것이다.The present invention relates to a paste-like composition for sealing and vibration damping of an automotive panel having excellent curability, adhesiveness, sealing property, and vibration damping property.
종래의 자동차의 대쉬 패널부, 플러오 패널부, 사이드 패널부등에 적용하고 있는 제진재는 아스팔트 재질의 시트형태가 대부분으로서 그와같은 시트형태의 제진제는 수작업에 의하므로 접착성 불량 및 작업능률지하와 굴곡부위에 대한 정밀한 밀착이 어려울 뿐 아니라 차종별에 따라 소재 및 형상을 구분해야하는 불편이 있었으며, 또한 시트상이어서 자동화 작업이 불가능한 단점이 있었다.The vibration damping material applied to the dash panel part, the plug-in panel part, the side panel part of the conventional automobile is mainly in the form of an asphalt sheet, and such a sheet-type damping agent is made by hand, so it is poor in adhesion and work efficiency. It was difficult to precisely adhere to the basement and the bent part as well as the inconvenience of having to distinguish the material and shape according to the vehicle type, and also had the disadvantage that automation work was impossible because it was in the form of a sheet.
본 발명은 이상과 같은 종래의 자동차 패널의 실링 및 제진용 소재의 결함을 완전 배제하기 위해 실링제겸 제진제를 페이스트상으로 하여 스프레이 도장이 가능하도록 한 자동차 패널의 실링 및 제진용 페이스트상 조성물을 제공코저 하는 것으로서 이를 실예를 들어 상세히 설명하면 다음과 같다.The present invention provides a paste-like composition for sealing and vibration damping of a vehicle panel which enables spray coating using a sealant and a vibration damper in the form of a paste in order to completely eliminate defects in the sealing and vibration damping material of the conventional automotive panel as described above. If this is described in detail as an example to the nose as follows.
본 발명은 아크릴 수지 에멀젼이나 초산비닐 수지 에멀젼중에서 선택된 어느 한가지 15~35중량%충전제로서 실리카, 코팅 또는 비코팅 탄산칼슘 및 탈크분말들중에서 선택된것 중 어느 1종이나 2종의 혼합물 30~40중량%에 통상의 소포재로서 솔비탄모노올레이트 2~6중량%, 통상의 유화제로서 라우릴아민아세테이트2~7중량%, 안정제로서 DLP(Dibasic Lead Phoshite) 0.3~3중량%, 가소제겸 점도조절용 탈이온수 1~5중량%, 통상의 발포제로서 지방산디에타놀아민 0.3~3중량%를 각각 첨가한 것을 주성분으로 하고 상기 주성분에 대하여 제진제로서 마이카(MICA)파우다 10~30중량%, 페놀(PHENOL) 수지 접착제1~6중량%를 첨가한 것을 특징으로한 것으로서, 외관은 회색 또는 검정색의 페이스트로상이며 점도는 50,000~150,000CPS 범위를 (점도계 : BROOK FILD, RVDV II로) 갖는 것이다.The present invention is any one of 15 to 35% by weight of the filler selected from acrylic resin emulsion or vinyl acetate resin emulsion, 30-40% by weight of any one or two selected from silica, coated or uncoated calcium carbonate and talc powder. 2 to 6% by weight of sorbitan monooleate as a normal antifoaming material, 2 to 7% by weight of laurylamine acetate as a common emulsifier, 0.3 to 3% by weight of DLP (Dibasic Lead Phoshite) as a stabilizer, plasticizer and viscosity control 1 to 5% by weight of deionized water and 0.3 to 3% by weight of fatty acid diethanolamine were added as a general blowing agent, respectively. 10 to 30% by weight of MICA powder as a damping agent, and phenol (PHENOL) ) It is characterized by adding 1 to 6% by weight of the resin adhesive, the appearance is gray or black paste-like, the viscosity is 50,000 ~ 150,000CPS range (viscosity: BROOK FILD, RVDV II).
상기에서 아크릴 수지 에멀젼이나 초산비닐수지 에멀젼의 첨가량이 15중량% 미만이거나 35중량%이상이면 접착성 및 가공성이 저하될 우려가 있고, 제진성에 악영향을 줄 수 있으며, 또한 충전제로 사용하는 실리카, 코팅 또는 비코팅 탄산칼슘 및 탈크분말들은 30중량% 미만이면 탄성력이 저하될 우려가 있고, 40중량%를 넘으면 탈이온수가 많이 요구되어 물성저하의 문제점이 있으며, 소포제는 2중량% 미만을 사용하면 페이스트내의 기포 제거가 어려워 조성물을 도포하여 경화시켰을 때 도포면에 핀홀등이 발생할 우려가 있고, 6중량%를 넘으면 내수성 및 접착력이 저하될 우려가 있다.When the amount of the acrylic resin emulsion or the vinyl acetate resin emulsion is less than 15% by weight or 35% by weight or more, there is a possibility that the adhesiveness and processability may be reduced, which may adversely affect the vibration damping properties, and is also used as a filler. If the coated or uncoated calcium carbonate and talc powder is less than 30% by weight, the elastic force may be lowered. If the amount is more than 40% by weight, deionized water is required. It is difficult to remove bubbles in the paste, and when the composition is applied and cured, pinholes or the like may occur on the coated surface. When the content exceeds 6% by weight, the water resistance and the adhesion may be lowered.
또한 유화제는 2중량% 미만을 사용하면 페이스트의 반응시 가공성 저하의 문제가 생길 수 있고 7중량%을 넘으면 접착력이 떨어지거나 내수성이 저하될 수 있다.In addition, when the emulsifier is used less than 2% by weight may cause a problem of workability deterioration during the reaction of the paste, when the emulsifier exceeds 7% by weight may reduce the adhesion or water resistance.
또한 안정제는 0.3중량% 미만을 사용하면 내열성이 저하될 수 있고, 3중량%을 넘으면 경도가 증가되는 문제점이 있다.In addition, when the stabilizer is used less than 0.3% by weight, the heat resistance may be lowered, when the stabilizer exceeds 3% by weight there is a problem that the hardness is increased.
또한 탈이온수는 1중량%미만이면 가공성의 저하와 점도 상승이 문제될 수 있고 5중량%을 넘으면 점도 저하와 상온 작업후 페이스트의 막 형성이 늦어지는 문제가 있을 뿐 아니라, 가공성에 영향을 주제된다. 또한 발포제는 0.3중량%미만이면 조성물의 도포 경화후 외관에 기포가 발생하여 외관이 불균일한 모양을 나타낼 수 있으며, 3중량%을 넘으면 과다한 발포가 이루어지기 때문에 오픈셀(OPEN CELL)이 발생되어 제진성이 저하되는 문제점이 있다.In addition, deionized water of less than 1% by weight may cause problems in processability and increase in viscosity, and in the case of more than 5% by weight, deionized water may not only have a problem of slowing viscosity and delayed film formation after normal temperature operation, but also affects processability. . In addition, if the foaming agent is less than 0.3% by weight, bubbles may appear in the appearance after the coating and curing of the composition, which may result in an uneven appearance, and when the foaming agent exceeds 3% by weight, an open cell is generated due to excessive foaming. There is a problem that the integrity is lowered.
또한 마이카(MICA)는 10중량%미만이면 제진성이 저하되고, 30중량%이상이면 조성물의 가공성이 저하되기 쉽다.If the MICA is less than 10% by weight, the damping property is lowered, and if it is 30% by weight or more, the processability of the composition tends to be lowered.
또한 페놀수지는 첨가량이 1중량%미만이면 접착력 및 경도가 저하될 수 있고, 6중량%를 넘으면 과다한 첨가로 인하여 경도가 증가하고, 저장안정성의 문제가 생기게 된다.In addition, if the amount of the phenol resin is less than 1% by weight, the adhesive strength and hardness may be lowered. If the amount of the phenol resin exceeds 6% by weight, the hardness increases due to excessive addition, resulting in a problem of storage stability.
여기에서 상기 조성물의 각성분에 따른 작용효과를 더욱 상세히 설명하면 다음과 같다.Here will be described in more detail the effect of each component of the composition as follows.
아크릴 수지 에멀젼(SOLID 50±1%, PH 3~4)은 점탄성 특성을 나타내어 제진성을 부여하면서 접착성을 나타내는데 유리하며, 실리카(입경 13, 비중 2.64)등 중전제는 탄성을 부여하면서 체적을 증가시킴과 동시에 성형성 및 작업성을 향상시키게 되어 원가절감 효과가 있을 뿐 아니라 탄성율을 높이는데 큰 효과를 갖게 된다.Acrylic resin emulsion (SOLID 50 ± 1%, PH 3 ~ 4) exhibits viscoelastic properties, which is advantageous in showing adhesion while providing vibration damping, and heavy neutralizers such as silica (particle size 13 and specific gravity 2.64) give elasticity and increase volume. Simultaneously with the increase of formability and workability, not only cost reduction effect but also a great effect to increase the elastic modulus.
또한 소포제는 기포를 제거 및 방지하기 위하여 사용하였으며, 유화제는 조성 물질들의 유화분산성을 높혀 안정한 에멀존을 만들기 위한 것이며, 안정제 (DIBASIC LEAD PHOSPHITE)는 130℃ 이상에서 변색방지 및 노화 방지를 위하여 사용하였으며 발포제(입경예: 13.1um)는 아크릴 수지 에멀젼이 가열될 때 수분에 의해 기포가 형성시 균일하게 발포 셀(CELL) 을 형성토록 하기 위한 것이며, 탈이온수는 기소제겸 점도 조절 역할을 하기 위한 것이며, 마이카(325 MESH)는 제진성을 높이는데 결정적인 요소가 되는 것이다. 또한 페놀수지(비중: 1.07)는 아크릴 에멀젼 페이스트에 대한 접착제로서 사용된다.In addition, the antifoaming agent was used to remove and prevent bubbles, the emulsifier is to create a stable emulsion zone by increasing the emulsion dispersibility of the composition materials, the stabilizer (DIBASIC LEAD PHOSPHITE) is used to prevent discoloration and aging at 130 ℃ or higher Foaming agent (particle size: 13.1um) is to form a foaming cell (CELL) uniformly when bubbles are formed by moisture when the acrylic resin emulsion is heated, deionized water is to act as a plasticizer and viscosity control. , Mica (325 MESH) is to be the decisive factor in improving the vibration damping. Phenol resins (specific gravity: 1.07) are also used as adhesives for acrylic emulsion pastes.
본 발명의 페이스트상 조성물은 최종제품의 비중이 1.4~1.6이상의 페이스트 상의 조성물로 구성된다.The paste composition of the present invention is composed of a paste composition having a specific gravity of 1.4 to 1.6 or more.
