Description
본 발명은 자동차용 펌프등과 같이 반복하여 만곡시켜 유체에 압력을 가하거나 만곡 변위를 이용해서 압력의 측정과 유체의 개폐 실행할 때 사용되는 부품인 다이어프램에 사용되는 직물에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fabric used in a diaphragm which is a part used for repeatedly bending a fluid, such as an automobile pump, to apply pressure to a fluid or to perform pressure measurement and fluid opening and closing using a curved displacement.
일반적으로 얇은 막을 의미하는 다이아프램은 펌프등과 같은 부품에서 반복하여 만곡시켜 유체에 압력을 가하거나 만곡 변위를 이용해서 압력의 측정과 유체의 개폐 실행할 때 사용되는 부품으로서 자동차에 다양하게 사용되고 있는데, 그 구조를 살펴보면 탄성체와 탄성체의 운동을 안정적으로 보강하는 직물로 구성된다.The diaphragm, which generally means a thin membrane, is used in a variety of applications in automobiles, such as a pump or the like, which is repeatedly bent to repeatedly bend the fluid to apply pressure to the fluid or to measure the pressure and to open and close the fluid. Looking at the structure, it consists of a fabric that stably reinforces the movement of the elastic body and the elastic body.
이러한 보강직물은 탄성체에 혼입 또는 복합함으로써 재료가 변형될 수 있는 한도, 강도 등을 개선한 것을 말한다. 사용되는 섬유로는 탄소섬유, 유기 기능섬유(아라미드 섬유), 유리섬유, 세라믹 섬유 등이 있다.Such a reinforcing fabric means that the reinforcing fabric is improved in strength, etc. so long as the material can be deformed by incorporation or compounding in the elastic body. The fibers to be used include carbon fibers, organic functional fibers (aramid fibers), glass fibers, and ceramic fibers.
최근에는 자동차의 성능향상으로 인해 고온에서 열적안정성을 가지는 아라미드원단의 사용이 많아지고 있다. 이러한 아라미드 섬유는 높은 내열성을 보이는 대표적인 슈퍼섬유로 고강도 특성을 가져 슬링바 방탄복 등에 주로 사용되는 파라계 아라미드와 내열성 열적 안정성 및 전기절연성으로 방화복 자동차 내열보강 섬유 절연지 등으로 사용되는 메타계 아라미드 섬유로 크게 분류된다.In recent years, the use of aramid fabrics having thermal stability at high temperatures has been increasing due to improved performance of automobiles. Such aramid fiber is a typical super fiber having high heat resistance and has a high strength property and is a meta-based aramid fiber used as a para-aramid used mainly in a sling bar body armor and the like and a thermostable thermally stable and electrically insulated fireproofing automobile heat- .
최근에는 탄성체가 고무재질로 이루어지고, 보강원단이 아라미드 섬유로 구성된 다이어프램이 고온 고압의 가혹한 환경이나 연속적인 진동 충격에 강하고, 탄성이 우수한 장점이 있어서 많이 사용되고 있다. 이와 같이 고무에 아라미드 섬유를 보강섬유로 결합한 예로서 대한민국공개특허제10-2010-0098470호(공개일자 2010년09월 07일)에는 고탄성의 클로로프렌 고무(Polychloroprene)를 매트릭스 수지로 하고, 고강도의 아라미드 섬유를 보강섬유로 하는 섬유보강 고무 복합재료의 제조방법이 소개되어 있다. 상기 제조방법은 a) 아라미드 섬유직물을 플라즈마 처리하는 단계와 b) 클로로프렌 고무를 가열하거나, 클로로프렌 고무와 가교제를 유기용매에 용해한 고무조성물을 제조하는 단계와 c)상기 a) 단계의 아라미드 섬유직물에 b)단계의 고무조성물을 도포한 후, 압착하여 프리프레그를 제조하는 단계와 d) 상기 프리프레그를 적층한 후 경화하는 단계로 이루어진다. In recent years, a diaphragm made of a rubber material and a reinforced fabric made of aramid fiber has been widely used because it is resistant to harsh environments such as high-temperature and high-pressure, continuous vibration, and elasticity. As disclosed in Korean Patent Laid-Open No. 10-2010-0098470 (published on September 07, 2010), for example, an aramid fiber is bonded to rubber by a reinforcing fiber, a high-elasticity chloroprene rubber (Polychloroprene) is used as a matrix resin, A method of manufacturing a fiber reinforced rubber composite material using fibers as reinforcing fibers has been introduced. The process comprises the steps of: a) plasma treating the aramid fiber fabric, b) heating the chloroprene rubber, or preparing a rubber composition in which the chloroprene rubber and the crosslinking agent are dissolved in an organic solvent, and c) contacting the aramid fiber fabric of step a) b) applying the rubber composition of the step b), followed by pressing to produce a prepreg; and d) laminating the prepreg and curing.
그러나 이러한 방법에서는 상기 프리프레그를 제조하기 위하여 먼저 보강섬유를 플라즈마 처리해야 하기때문에 대규모 시설이 필요하고, 따라서 제조비용이 높은 문제가 있다. However, in this method, since the reinforcing fibers must be subjected to the plasma treatment in order to prepare the prepreg, a large-scale facility is required, and thus the manufacturing cost is high.
또한, 고온 고압용 복합소재로서 실리콘 고무를 매트릭스 수지로 사용하고, 동시에 보강섬유와의 접착강도를 개선하기 위한 연구도 소개되어 있다. 즉, 매트릭스 수지와의 결합력을 향상시키기 위하여 보강섬유에다 아미노프로필 트리에톡시실란이나 비닐트리 에톡시실란을 주성분으로 하는 실란계 커플링제를 도포하는 것이다. 그러나, 이 경우에는 상기 커플링제를 톨루엔이나 자일렌, 에탄올, 메탄올 등의 유기 용제에 희석하여 사용해야 하기 때문에 작업공정에서 작업자가 인체에 유해한 휘발성유기물질에 노출되는 등 작업환경이 열악하고, 화재 위험이 상존할 뿐 아니라, 박리강도가 다소 취약하여 이에 대한 개선의 필요성이 요구되어 왔다.Further, studies have been made to use silicone rubber as a matrix resin as a high-temperature and high-pressure composite material and at the same time to improve the bonding strength with reinforcing fibers. That is, a silane-based coupling agent containing aminopropyltriethoxysilane or vinyltriethoxysilane as a main component is applied to the reinforcing fiber in order to improve the bonding strength with the matrix resin. However, in this case, since the coupling agent must be diluted with an organic solvent such as toluene, xylene, ethanol or methanol, the work environment is poor, And the peel strength is somewhat weak, so that there is a need for improvement of the peel strength.
그러므로 본 발명은 자동차용 펌프등과 같이 반복하여 만곡시켜 유체에 압력을 가하거나 만곡 변위를 이용해서 압력의 측정과 유체의 개폐 실행할 때 사용되는 부품인 다이어프램에 사용되는 직물로서 고온에서 열적 내구성을 가지고 유체의 이송 시 내압성능이 우수한 자동차용 다이어프램용 원단을 제공하는 것을 목적으로 한다Therefore, the present invention is a fabric used for a diaphragm, which is used for pressure measurement and fluid opening / closing operation by repeatedly bending a fluid such as an automobile pump or applying a pressure to a fluid or using a curved displacement, and has thermal durability at a high temperature And an object of the present invention is to provide a fabric for a diaphragm for an automobile which is excellent in pressure resistance performance during fluid transportation
그러므로 본 발명에 의하면, 원사로서 아라미드 방적사를 2합하여 경사 및 위사로 사용하고, 경사로 사용하기전에 호제로 사이징하고 제직한 후, 90~98℃, 35~45min간 지거에서 전처리한 후 NaOH(농도 50%) 80~90 g/ℓ, 정련제 15~25 g/ℓ를 함유하는 정련욕에서 90~100℃에서 정련을 통하여 호발한 후 건조한 후, 수성 실란계 커플링제를 함침하고 180~200℃에서 큐어링하고, 200~230℃, 35~50m/min의 조건으로 열처리하는 것을 특징으로 하는 아라미드직물을 사용한 자동차용 다이어프램용 원단의 제조방법이 제공된다.Therefore, according to the present invention, two aramid yarns as yarn are used as warp yarns and weft yarns before sizing, and then pretreated at 90 to 98 DEG C for 35 to 45 minutes, %) 80 to 90 g / l, and a refining agent 15 to 25 g / l, and dried at 90 to 100 ° C., dried, impregnated with an aqueous silane coupling agent and cured at 180 to 200 ° C. Ring and subjected to a heat treatment at a temperature of 200 to 230 ° C and a temperature of 35 to 50 m / min. A method for manufacturing a fabric for an automobile diaphragm using the aramid fabric is provided.
이하 본 발명을 보다 상세히 설명하기로 한다. Hereinafter, the present invention will be described in more detail.
본 발명의 자동차용 다이어프램용 원단의 제조방법은 아라미드 방적사를 사용하여 보강직물을 제조하고, 상기 보강직물을 정련을 하여 호발한 후 실란계 수성 커플링제를 함침한 후 큐어링(curing)하는 것이다. 상기에서 아라미드 섬유는 메타계 아라미드 섬유를 사용한다.The manufacturing method of the diaphragm for automobile diaphragm according to the present invention is to manufacture a reinforcing fabric by using an aramid yarn, refining the reinforcing fabric, impregnating the fabric with a silane based coupling agent, and then curing the reinforcing fabric. In the above, the aramid fiber uses a meta-based aramid fiber.
본 발명에서는 원사로서 아라미드 방적사를 2합하여 경사 및 위사로 사용하고, 경사로 사용하기전에 호제로 사이징하고 제직한다. In the present invention, two yarns of aramid yarn as yarn are used as warp and weft yarns, and are weighed and weighed before warp yarns are used.
내열성과 내구성을 확보하기 위하여 본 발명의 다이아프램의 보강재로는 아라미드 소재를 적용하고자 한다. 다이아프램의 특성인 유연성 확보를 위해 보강 직물의 증량을 최소화 할 수 있는 원사의 굵기를 선정한다. 아라미드 20수('S), 30수로는 직물을 사용하기에는 두께가 두꺼워 40수('S) 방적사를 사용하고, 조직은 고무와의 접촉면적과 작업성을 고려하여 평직을 적용한다. In order to secure heat resistance and durability, an aramid material is used as a reinforcing material of the diaphragm of the present invention. In order to ensure the flexibility of the diaphragm, the thickness of the yarn that minimizes the increase of the reinforcing fabric is selected. Aramid 20 ('S), 30 The water is thicker to use the fabric, and it uses 40 yarns (' S) yarn, and the tissue applies plain weave considering the contact area with rubber and workability.
원사별 평직에 대한 중량은 다음과 같다. 원사는 방적사를 사용하는 대신 직물의 강도를 고려해 2합사를 적용하였다.The weight for plain weave by yarn is as follows. Instead of using a spun yarn, the yarn was subjected to 2 yarns in consideration of the strength of the fabric.
본 발명에서는 상기 아라미드 방적사를 2합하여 위사 및 경사로 사용하는데, 경사로 사용할 경우 사이징을 통하여 사를 구성하는 단섬유를 집합 결속시켜 꼬임을 방지함과 동시에 사의 표면을 보호하여, 평활성을 증대시켜서 제직성을 향상 시킬 수 있다. 본 발명에서는 경사로 아라미드 방적사를 적용하였으므로 전분 25~30%, PVA 60~70%, 왁스 4.8~7%, 오일 0.2~3%를 혼합하여 호제로 사용하는 것이 직기에서 개구성을 양호하게 하며 낙호발생을 적게 할 수 있어 바람직하다.In the present invention, two aramid yarns are used as weft yarns and warp yarns. When yarns are used as the warp yarns, the short fibers constituting yarns are gathered and bound together by sizing to prevent twisting, while protecting the yarn surface, Can be improved. In the present invention, since the ramp aramid yarn is applied, it is preferable to use 25 to 30% of starch, 60 to 70% of PVA, 4.8 to 7% of wax and 0.2 to 3% of oil, Can be reduced.
본 발명의 경우 후가공으로 염색 등의 공정을 거치지는 않지만 프라이머인 수성 실란계 커플링제 처리를 통한 실리콘계 고무와의 접착력을 강화하기 위해서 프라이머인 수성 실란계 커플링제가 직물에 고르게 흡수 및 침투를 하기위해 호제를 완전히 제거하는 것이 중요하므로 정련을 통하여 호발을 실시한다. 제직 후 90℃, 35~45min 지거에서 전처리한 후 NaOH(농도 50%) 80~90 g/ℓ, 정련제 15~25 g/ℓ를 함유하는 정련욕에서 90~100℃에서 정련을 통하여 호발한 후 건조하게 된다.In the case of the present invention, in order to enhance the adhesion with the silicone rubber through the treatment of the aqueous silane coupling agent as a primer, the aqueous silane coupling agent, which is a primer, It is important to completely remove the gypsum so that the gypsum is diluted through refining. After pre-treatment at 90 ° C for 35 to 45 min after weaving, the product was developed by refining at 90 to 100 ° C in a refining bath containing 80 to 90 g / l NaOH (concentration 50%) and 15-25 g / l refining agent And dried.
이후 수성 실란계 커플링제를 함침하고 180~200℃에서 큐어링하고, 200~230℃, 35~50m/min의 조건으로 열처리하여 본 발명의 아라미드직물을 사용한 자동차용 다이어프램을 제조하게 된다.Thereafter, an aqueous silane coupling agent is impregnated and cured at 180 to 200 ° C. and heat-treated at 200 to 230 ° C. and 35 to 50 m / min to produce an automotive diaphragm using the aramid fabric of the present invention.
상기 수성 실란계 커플링제는 n-2-아미노에틸-3-아미노프로필 트리메톡시 실란, 3-글리시독시 프로필트리메톡시 실란, 3-메타크릴 옥시프로필 트리 메톡시 실란, 3-머캅토 프로필트리 메톡시 실란 중 어느 하나이상인 수성 실란계 화합물과 아세트산, 물을 중량비 2:0.6:16~2:1:18로 혼합한 수성 실란계 커플링제인 것이 바람직하다.The aqueous silane coupling agent may be selected from the group consisting of n-2-aminoethyl-3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, 3-methacryloxypropyltrimethoxysilane, 3- Trimethoxysilane, and an aqueous silane coupling agent in which acetic acid and water are mixed at a weight ratio of 2: 0.6: 16 to 2: 1: 18.
상기 실란 화합물들은 모두 수용성으로서 물에 비교적 잘 용해되는 특성이 있으나, 상기 아세트산이 실란 화합물의 수용성을 향상시켜 주는 기능을 한다. 따라서, 상기 아세트산의 함량이 중량비로 실란 화합물 2에 대하여 0.6 미만이면 실란 화합물이 물에 완전히 용해되지 않는 문제가 있고, 반대로 1초과면 상기실란계 수성 커플링제의 pH가 과도하게 높아지는 문제가 있다.The silane compounds are all water-soluble and have a property of dissolving in water relatively well, but the acetic acid functions to improve the water-solubility of the silane compound. Therefore, if the content of acetic acid is less than 0.6 based on the weight of the silane compound 2, there is a problem that the silane compound is not completely dissolved in the water. On the other hand, when the content is more than 1, the pH of the silane-based aqueous coupling agent becomes excessively high.
또한 상기 물은 실란 화합물을 직물에 고르게 도포하는 매질 기능을 하며, 그 함량이 중량비로 실란 화합물 2에 대하여 16 미만이면 실란화합물의 농도가 너무 높아져 비용의 손실이 따르고, 반대로 함량이 중량비로 실란 화합물 2에 대하여 18을 초과하면 실란 화합물 처리의 효과가 충분하지 못한 문제가 있다.Further, the water functions as a medium for uniformly applying the silane compound to the fabric. If the content of the silane compound is less than 16 per weight of the silane compound 2 in terms of the weight ratio, the concentration of the silane compound becomes too high resulting in cost loss. On the contrary, 2, the effect of treating the silane compound is insufficient.
이와 같이 구성된 실란계 수성 커플링제에 상기 아라미드 직물을 침지하여 함침한 후, 3.5~4.5kg/㎠ 압력의 망글 롤러(mangle roller)를 이용하여 아라미드 직물에 함침된 실란계 수성 커플링제의 양을 일정하게 분산시켜 주는데, 이때 압력이 3.5 kg/㎠ 미만이면 상기 아라미드 직물의 표면에 커플링제가 불균일하게 분포하는 문제가 있고, 반대로 4.5kg/㎠ 초과하면 아라미드 직물이 커플링제에 충분히 함침되지 못하는 문제가 있다. After the aramid fabric is impregnated and impregnated with the silane-based aqueous coupling agent thus formed, the amount of the silane-based aqueous coupling agent impregnated into the aramid fabric is measured by a mangle roller at a pressure of 3.5 to 4.5 kg / If the pressure is less than 3.5 kg / cm < 2 >, there is a problem that the coupling agent is unevenly distributed on the surface of the aramid fabric. On the other hand, if the pressure is more than 4.5 kg / cm < 2 >, the problem that the aramid fabric is not sufficiently impregnated with the coupling agent have.
그리고, 상기와 같이 망글롤러로 압착한 후에는 180~200℃에서 큐어링하고, 200~230℃, 35~50m/min의 조건(텐터 10챔버기준)으로 열처리하여 아라미드 직물 자체의 인장강도 및 인장탄성률이 현저히 증가되도록 한다. 이때 큐어링 온도가 180℃ 미만이면 인장강도 및 인장탄성률에서 주목할 만한 변화가 없고, 반대로 200℃ 초과이면 상기 아라미드 직물이 수축 손상되는 문제가 있다.Then, after being compressed by the mesh rollers as described above, curing is performed at 180 to 200 ° C. and heat treatment is performed under the conditions of 200 to 230 ° C. and 35 to 50 m / min (based on the tenter 10 chamber) to determine the tensile strength of the aramid fabric itself, So that the modulus of elasticity is significantly increased. If the curing temperature is lower than 180 ° C, there is no noticeable change in tensile strength and tensile elastic modulus. On the contrary, if the curing temperature is higher than 200 ° C, the aramid fabric is shrunk and damaged.
이와 같이 제조된 다이아프램용 원단은 별도공정에서 고무와 결합하여 다이아프램으로 제조되는데, 그 예로는 상기한 바와 같이 큐어링한 아라미드 직물의 일면 또는 양면에 아라미드 직물의 양면 각각 면적 1㎡ 당 무게가 460~500g인 실리콘 고무판을 적층하고, 200~220℃의 온도 하에서 3~3.5kg/㎠ 의 압력으로 양면을 압착하여 다이아프램을 제조하게 된다.The diaphragm fabric thus manufactured is made of a diaphragm in combination with rubber in a separate process. For example, the aramid fabric having a cured aramid fabric has a weight per square meter of area of both sides of the aramid fabric A silicone rubber sheet having a thickness of 460 to 500 g is laminated and a diaphragm is produced by squeezing both surfaces at a pressure of 3 to 3.5 kg / cm 2 at a temperature of 200 to 220 ° C.
그러므로 본 발명에 의해 유체의 이송 시 내압성능을 향상하고 고온에서 열적 내구성이 우수한 다이어프램을 제공할 수 있으며, 편물과 대비하여 보다 강인하여 내파열압등과 내구성이 향상된 다이어프램을 제공할 수 있다.Therefore, according to the present invention, it is possible to provide a diaphragm capable of providing a diaphragm having improved resistance to internal pressure at the time of transfer of a fluid and having excellent thermal durability at high temperature, and being stronger than a knitted fabric, thereby improving diaphragm rupture pressure and durability.
