Description
본 발명은 수소연료전지 차량의 이온필터 및 스택 냉각장치용 호스의 보강소재에 관한 것이다. The present invention relates to a reinforcing material for a hose for an ion filter and a stack cooling device of a hydrogen fuel cell vehicle.
전세계적으로 환경적인 부분을 계속 부각함으로써 친환경차에 대한 선호도가 높아지고 있는 추세이며, 우리나라에서는 친환경자동차로서 전기자동차, 태양광자동차, 하이브리드 자동차, 연료전지자동차(이하 수소 전기차)등을 정의하고 있다. As environmental issues continue to be highlighted worldwide, the preference for eco-friendly vehicles is on the rise. In Korea, eco-friendly vehicles are defined as electric vehicles, solar vehicles, hybrid vehicles, and fuel cell vehicles (hereinafter referred to as hydrogen electric vehicles).
그 중 수소 전기차 시장은 2020년 이후 꾸준한 시장 확대가 예측되고 있는데, 수소 전기차를 구성하는 필수적인 요소기술은 수소와 산소를 반응시켜 전기를 발생시키는 장치인 스택(연료전지), 차량의 운전 상태에 맞게 수소와 공기를 공급하고 열관리를 하는 장치인 운전장치, 생성된 전기를 구동에 맞게 변환하는 장치인 전장장치, 연료인 수소를 저장하는 장치인 수소저장장치로 크게 이루어진다. Among them, the hydrogen electric vehicle market is expected to see steady market expansion after 2020. The essential element technologies that make up hydrogen electric vehicles are largely composed of a stack (fuel cell), a device that generates electricity by reacting hydrogen and oxygen; a driving device that supplies hydrogen and air according to the vehicle's driving condition and manages heat; an electrical device that converts the generated electricity to suit the driving condition; and a hydrogen storage device that stores hydrogen as fuel.
상기 요소 중 스택에서는 수소전지에서 전기로 변환하는데 있어서 공기 공급계통에 있는 가습기에 의해 발생하는 가습공기에 대한 전기전열 확보를 위해 이온 용출성이 낮은 호스를 사용하고 있다.Among the above elements, the stack uses a hose with low ion elution properties to secure electric heat for humidified air generated by a humidifier in the air supply system when converting hydrogen fuel cells into electricity.
이러한 수소연료전지 호스라인에서 기술적으로 검토해야 할 점은 호스 및 관련 구성 재질에서 방출하는 이물질들이 스택에 미치는 영향에 대한 확인, 실리콘 부산 방출물질인 사이클로실록산(Cyclosiloxanes)의 영향에 대한 경험, 호스 구성 외층 부분도 저 방출 재질로써 방출에 영향을 미치는지에 대한 검토가 필요하다.Technical considerations for these hydrogen fuel cell hose lines include confirmation of the impact of foreign substances emitted from hoses and related component materials on the stack, experience with the impact of cyclosiloxanes, a silicone by-product emission substance, and examination of whether the outer layer of the hose component is also a low-emission material that affects emissions.
종전의 호스 보강재는 폴리에스테르 필라멘트로 구성되어 편성물이나 직조 시 신율 혹은 탄성회복율이 미흡하여 호스부품의 내구성능이 저하되는 요인이 되었고, 실리콘 고무와 보강섬유간의 접착력이 취약하여 이에 대한 기술적 향상이 요구되고 있다. Conventional hose reinforcements are composed of polyester filaments, which have insufficient elongation or elastic recovery when knitted or woven, which has reduced the durability of hose parts. In addition, the adhesive strength between silicone rubber and reinforcement fibers is weak, and technological improvement in this regard is required.
그러므로 본 발명에서는 수소연료전지 차량의 이온필터 및 스택 냉각장치용 호스에 사용되는 보강섬유의 강도, 탄성회복율, 열수 치수변화율의 향상 및 실리콘과의 계면접착력 향상을 위한 폴리에스테르 경편물보강재를 제공하는 것을 기술적과제로 한다. Therefore, the technical task of the present invention is to provide a polyester warp-knit reinforcing material for improving the strength, elastic recovery rate, and thermal dimensional change rate of reinforcing fibers used in hoses for ion filters and stack cooling devices of hydrogen fuel cell vehicles, and for improving interfacial adhesion with silicone.
그러므로 본 발명에 의하면, 폴리에스테르 DTY를 사용하여 편직한 폴리에스테르 경편물기재에 수성 블록 폴리이소시아네이트 2~4중량%, 지방족 에폭시 3~9중량%, 트리데실알코올 EO부가 비이온계 침투제 1~3중량% 및 잔부로서 물을 함유한 수성 프라이머액을 동욕처리하여 함침 후 건열 열처리기로 170~190℃에서 큐어링하여 이루어진 것을 특징으로 하는 수소전기차 실리콘호스용 폴리에스테르 경편물보강재의 제조방법이 제공된다. Therefore, according to the present invention, a method for manufacturing a polyester warp knit reinforcement material for a hydrogen electric vehicle silicone hose is provided, characterized in that the polyester warp knit base material is knitted using polyester DTY, and an aqueous primer solution containing 2 to 4 wt% of an aqueous block polyisocyanate, 3 to 9 wt% of an aliphatic epoxy, 1 to 3 wt% of a nonionic penetrant having an EO component of tridecyl alcohol, and the remainder water is impregnated by bath treatment, and then cured at 170 to 190°C in a dry heat treatment unit.
이하 본 발명을 보다 상세히 설명하기로 한다,Hereinafter, the present invention will be described in more detail.
본 발명의 수소전기차 실리콘호스용 폴리에스테르 경편물보강재는 폴리에스테르 경편물기재에 프라이머를 동욕처리하여 함침 후 큐어링하여 이루어진 것으로서 상기 보강재에 실리콘수지를 함침하여 성형하여 수소연료전지 차량의 이온필터 및 스택 냉각장치용 호스를 제조할 수 있는 것이다.The polyester knitted reinforcing material for a hydrogen fuel cell vehicle silicone hose of the present invention is made by subjecting a polyester knitted material to a primer bath treatment, impregnating it, and curing it, and by impregnating the reinforcing material with silicone resin and molding it, it is possible to manufacture a hose for an ion filter and stack cooling device of a hydrogen fuel cell vehicle.
본 발명의 수소전기차 실리콘호스용 폴리에스테르 경편물보강재의 기재는 폴리에스테르 경편물기재로서 폴리에스테르 DTY사로 경편한 트리코트 편물을 사용하여 신율이 우수하며 내파열압 및 진동 저항을 향상시키는 한편, 삼각구조의 격자를 가지게 하여 조직의 강도를 향상시킬 수 있다. The base material of the polyester warp knitted reinforcing material for a hydrogen electric vehicle silicone hose of the present invention is a polyester warp knitted base material, and uses a warp tricot knitted fabric made of polyester DTY yarn, so that the elongation is excellent and the burst pressure and vibration resistance are improved, and the strength of the organization can be improved by having a triangular lattice structure.
특히, 본 발명에서는 폴리에스테르 DTY를 사용하여 강도와 탄성회복력 및 열수축률을 우수하게 할 수 있다. In particular, in the present invention, polyester DTY can be used to improve strength, elastic recovery, and heat shrinkage.
본 발명에서 폴리에스테르 DTY는 도 1에 도시된 바와 같이 두가닥의 폴리에스테르 연신필라멘트(1)를 제1피드롤러(2)로 공급하고 온도 180~200℃의 히터(3)를 통과시킨 후 가연기(4)에서 가연을 하면서, 제2피드롤러(5)를 통과시키고 인터레이스노즐(6)의 에어압 0.5~2.0kg/㎠으로 교락수 60~100개/m로 인터레이스하면서 제3피드롤러(7)를 통과시키되 제2피드롤러와 제3피드롤러간의 속도차에 의한 연신비 1.00~1.20으로 연신하고 사속 400~500m/분으로 권취롤(8)에 권취하여 제조된 폴리에스테르 DTY 인 것이 바람직하다.In the present invention, the polyester DTY is preferably a polyester DTY manufactured by supplying two polyester elongated filaments (1) to a first feed roller (2) as illustrated in FIG. 1, passing them through a heater (3) having a temperature of 180 to 200°C, twisting them in a twister (4), passing them through a second feed roller (5), interlacing them at an air pressure of 0.5 to 2.0 kg/cm2 of an interlace nozzle (6) with a number of interlacings of 60 to 100/m, and passing them through a third feed roller (7), while stretching them at a stretching ratio of 1.00 to 1.20 due to the speed difference between the second and third feed rollers, and winding them on a take-up roll (8) at a yarn speed of 400 to 500 m/min.
특히, 교락시 에어압의 경우 2.0kg/㎠ 초과인 경우에는 교락에 있어서 문제점이 발생하며, 0.5kg/㎠를 미만인 경우에는 교락이 형성되는데 있어서 문제점이 발생하므로 유의하여야 한다.In particular, when the air pressure during interlocking exceeds 2.0 kg/cm2, problems may occur in interlocking, and when it is less than 0.5 kg/cm2, problems may occur in forming interlocking, so care must be taken.
본 발명의 경편물보강재는 상기 폴리에스테르 DTY를 사용하여 편직한 폴리에스테르 경편물기재에 수성 블록 폴리이소시아네이트 2~4중량%, 지방족 에폭시 3~9중량%, 트리데실알코올 EO부가 비이온계 침투제 1~3중량% 및 잔부로서 물을 함유한 수성 프라이머액을 동욕처리하여 함침 후 160~170℃에서 큐어링하는 것이 편성물의 치수안정성 및 신장 탄성 회복력의 확보에 바람직하다.The knitted reinforcement material of the present invention is preferably prepared by impregnating a polyester knitted base material knitted using the polyester DTY with an aqueous primer solution containing 2 to 4 wt% of an aqueous blocked polyisocyanate, 3 to 9 wt% of an aliphatic epoxy, 1 to 3 wt% of a nonionic penetrant having an EO content of tridecyl alcohol, and the remainder water by bath treatment and then curing at 160 to 170°C, in order to secure dimensional stability and elongation elastic recovery of the knitted material.
상기 수성 프라이머액은 실리콘고무 같은 무기소재와 폴리에스테르 경편물 기재와 같은 유기소재를 결합하는데 중간역할로 작용하는데, 기계적 강도를 증진시키고 실리콘고무와의 접착성을 향상시키는 역할을 하여, 실리콘 호스의 접착-박리강도, 내구성 및 내후성 향상에 도움을 준다.The above-mentioned water-based primer acts as an intermediate in bonding inorganic materials such as silicone rubber and organic materials such as polyester knitted fabric substrates, and plays a role in increasing mechanical strength and improving adhesion with silicone rubber, thereby helping to improve the bond-peel strength, durability, and weather resistance of the silicone hose.
상기 수성 블록 폴리이소시아네이트는 실리콘 고무의 가교시 해리하여 고무와 섬유간의 결합력을 향상시키는 역할을 하는 것으로서 일본특허등록제4892261호의 수성 블록 폴리이소시아네이트를 사용하는 것이 바람직하다.The above-mentioned aqueous block polyisocyanate plays a role in improving the bonding strength between the rubber and fiber by dissociating during crosslinking of silicone rubber, and it is preferable to use the aqueous block polyisocyanate of Japanese Patent Registration No. 4892261.

상기 수성 블록 폴리이소시아네이트 2중량%미만인 경우에는 가교결합력의 부족으로 접착력이 저하되는 문제점이 발생하며, 4중량%를 초과하는 경우에는 과결합으로 인해 경도가 증가하는 문제점이 발생한다.When the amount of the above-mentioned water-based block polyisocyanate is less than 2 wt%, there is a problem of reduced adhesive strength due to insufficient cross-linking strength, and when it exceeds 4 wt%, there is a problem of increased hardness due to excessive bonding.
상기 지방족 에폭시는 다관능기의 바인더 역할을 하는 것으로서 3~9중량% 함유하는 것이 바람직한데, 3중량%미만인 경우에는 접착력이 저하하는 문제점이 발생하며, 9중량%를 초과하는 경우에는 가사 시간(pot life)이 단축되는 문제점이 발생한다.The above aliphatic epoxy acts as a binder for the polyfunctional group and is preferably contained in an amount of 3 to 9 wt%. However, if it is less than 3 wt%, the problem of reduced adhesive strength occurs, and if it exceeds 9 wt%, the problem of shortened pot life occurs.
특히, 본 발명에서는 상기 수성 블록 폴리이소시아네이트와 지방족 에폭시를 혼합하여 종전의 2욕 처리공법에 비해 공정시간을 단축할 수 있는 특징이 있다.In particular, the present invention has the characteristic of being able to shorten the process time compared to the conventional two-bath treatment method by mixing the aqueous block polyisocyanate and the aliphatic epoxy.
트리데실 알코올 EO(Ethylene Oxide) 부가 비이온계 침투제는 바인더와 가교제를 섬유로 쉽게 이행(移行)하는 역할을 하는 것으로서 1~3중량% 함유하는 것이 바람직한데, 1% 미만인 경우에는 접착력이 저하하는 문제점이 발생하며, 3중량%를 초과하는 경우에는 침투 역할의 증진효과가 나타나지 않았다. The tridecyl alcohol EO (Ethylene Oxide) nonionic penetrant plays a role in facilitating the transfer of the binder and crosslinking agent to the fiber, and it is preferable to contain 1 to 3 wt% of the penetrant. However, when it is less than 1 wt%, the problem of reduced adhesive strength occurs, and when it exceeds 3 wt%, the effect of enhancing the penetrating role does not appear.
이렇게 폴리에스테르 경편물기재에 프라이머를 동욕처리하여 함침한 후 170~190℃에서 큐어링하여 실리콘호스 보강재를 제조할 수 있으며, 이 실리콘고무호스 보강재에 실리콘고무를 카렌다로 시트화하여 이를 여러겹으로 만든 후 이를 성형 및 가교반응하여 수소전기차 실리콘호스를 제조할 수 있게 된다.In this way, a polyester warp knitted material is impregnated with a primer by a homogeneous bath treatment and then cured at 170 to 190°C to produce a silicone hose reinforcing material. In addition, silicone rubber is sheeted onto this silicone rubber hose reinforcing material using a calendar to form multiple layers, and then molded and crosslinked to produce a hydrogen electric vehicle silicone hose.
그러므로 본 발명에 의하면 수소연료전지호스의 내구성능을 증대하기 위해 보강섬유를 종전의 폴리에스테르 필라멘트를 대신하여 교락에 의한 폴리에스테르 DTY를 사용함으로써 신도와 강도를 향상시켜 편성물을 제조하였으며, 에폭시 수지와 가교제를 침투제와 병행하여 동욕처리하여 보강섬유와 실리콘 고무와 접착력향상을 도모하였으며, 가교성능향상을 위해 실리콘 고무와 가교 온도조건과 동등한 수준의 수성 블록 폴리이소시아네이트를 사용하여 보강섬유 실리콘 고무간 접착성능을 향상시켜 수소연료전지 냉각호스의 내구성능을 향상시킬 수 있었다. Therefore, according to the present invention, in order to increase the durability of a hydrogen fuel cell hose, a knitted fabric was manufactured by improving elongation and strength by using polyester DTY by entanglement instead of the conventional polyester filament as the reinforcing fiber, and an epoxy resin and a crosslinking agent were co-treated with a penetrating agent to improve the adhesion between the reinforcing fiber and silicone rubber, and in order to improve the crosslinking performance, an aqueous block polyisocyanate having a level equivalent to that of the silicone rubber and the crosslinking temperature was used to improve the adhesive performance between the reinforcing fiber and silicone rubber, thereby improving the durability of the hydrogen fuel cell cooling hose.
