Abstract
Description
본 발명은 기계적 특성이 우수하고 내구성이 양호한 에어백용 원단에 관한 것이다.The present invention relates to an airbag fabric having excellent mechanical properties and good durability.
최근 각종 교통수단 특히 자동차에는 충돌시 승객 보호용 안전장치인 에어백 시스템이 실용화되고 있는 추세이다. 이러한 에어백은 내구성이 약하여 장기간 보관시 기계적 특성이 급격히 저하되면 에어백의 실제 작동시 시스템의 커다란 문제점으로 떠오르게 된다.Recently, the airbag system, which is a safety device for protecting passengers in the event of a collision, has been in practical use in various transportation methods, especially automobiles. Such airbags are weak in durability, and if the mechanical properties are sharply degraded during long-term storage, they become a big problem of the system in actual operation of the airbag.
에어백은 실제 작동하기 전에 자동차 핸들, 대시보드내에 오랜 시간동안 협소한 곳에 접혀져서 보관되어 있어 하절기에는 자동차내부의 온도가 고온으로 올라가며 또한 엔진부와 근접된 곳에 있어서 수납되어져 있는 에어백에 고온의 열이 반복적으로 작용되며, 동절기에는 그와 반대로 저온의 반복 열작용을 받아서 에어백 원단의 기계적 특성이 저하된다.The airbag is stored in a narrow place in the steering wheel and dashboard for a long time before it is actually operated.In summer, the temperature inside the car rises to a high temperature. In winter, the mechanical properties of the airbag fabric are deteriorated due to repeated low-temperature repeated heat in winter.
실제 에어백 시스템이 작동할 경우 가스발생기(인플레이트)내에서 발생하는 고온(약 400℃)의 가스가 에어백 원단 표면에 닿을 경우 에어백 원단의 물성이 하락되어 이로 인해 그 기계적 특성이 더욱 감소된다.When the actual airbag system is operated, when the high temperature (about 400 ° C) gas generated in the gas generator (inplate) touches the airbag fabric surface, the physical properties of the airbag fabric are reduced, thereby further reducing its mechanical properties.
따라서 에어백 원단은 통상 나일론 66의 평직에 클로로프렌 고무를 도포하여 에어백시스템의 작동시의 고온의 가스에 대한 내열성을 향상시키고 공기투과를 차단하게 된다.Accordingly, the airbag fabric is usually coated with chloroprene rubber on the plain weave of nylon 66 to improve the heat resistance to the hot gas during operation of the airbag system and to block air permeation.
그러나 클로로프렌 고무를 장기간 보관시 열분해하여 할로겐화수소를 발생하고, 이 할로겐화 수소는 나일론 원단을 열화시켜 물성을 크게 저하시키게 된다.However, when the chloroprene rubber is stored for a long time, pyrolysis generates hydrogen halide, and the hydrogen halide deteriorates nylon fabric, thereby greatly deteriorating physical properties.
이와 같은 문제점을 해결한 종래방법으로는 일본 공개특허공보소 49-47692호를 들 수 있다.As a conventional method which solved such a problem, Unexamined-Japanese-Patent No. 49-47692 is mentioned.
즉, 나일론 기포지위에 클로로프렌 고무층을 도포할시 클로로프렌 고무에 지르코늄계 화합물을 첨가하여 발생되는 할로겐화 수소를 흡착시켜 포지의 내구성 저하를 방지하는 방법으로서, 이 방법으로는 발생되는 할로겐화수소를 완벽하게 차단하기 힘든 문제점이 있다.In other words, when applying a chloroprene rubber layer on the nylon bubble paper, a method of preventing the durability of the forge by adsorbing hydrogen halide generated by adding a zirconium-based compound to the chloroprene rubber, which completely blocks the hydrogen halide generated by this method There is a problem that is difficult to do.
또한 일본 공개특허공보 평 2-133268호에서는 클로로프렌 고무층과 나일론 기포사이에 할로겐 비함유고무가 75% 이상인 고무층을 도포하여 할로겐화수소의 나일론 기포에의 영향을 막아 내구성을 향상시키는 방법을 제시하고 있으나, 이 경우 할로겐화수소의 침투방지를 위해 고무를 처리한 후 다시 클로로프렌 고무층을 도포함으로써 이중으로 도포가 되어 원단의 두께로 두꺼워지고, 수납공간도 커지는 단점을 갖고 있다.In addition, Japanese Patent Application Laid-Open No. 2-133268 proposes a method of improving durability by applying a rubber layer containing 75% or more of halogen-free rubber between a chloroprene rubber layer and a nylon bubble to prevent the effect of hydrogen halide on the nylon bubble. In this case, after the rubber is treated to prevent penetration of the hydrogen halide, the chloroprene rubber layer is applied again to double the thickness of the fabric, and the storage space is also increased.
본 발명에서는 상기와 같은 문제점을 완전히 개선한 것으로서 피복률이 26∼30인 나일론 66 기포지에 실리콘고무를 도포하여 제조된 에어백용 포지로서, 기포지로 사용되는 나일론 66 원사의 데니어는 400∼1,000 데니어이며, 또한 사용되는 실리콘고무는 비닐기를 가진 폴리실록산을 주쇄로 하고 백금촉매에 의해 경화되는 점도 300∼4,000 포아즈의 실리콘 고무이다.In the present invention, as a complete improvement of the above problems, the airbag for air bags prepared by applying a silicone rubber to a nylon 66 bubble paper having a coverage of 26 to 30, the denier of nylon 66 yarn used as a bubble paper is 400 to 1,000 denier In addition, the silicone rubber used is a silicone rubber having a viscosity of 300 to 4,000 poises having a main chain of polysiloxane having a vinyl group and cured by a platinum catalyst.
이때의 피복률은 다음과 같다.The coverage at this time is as follows.
이때 피복률이 26 미만인 경우는 에어백용 원단으로는 강도가 부족하고, 도포제가 원단사이에 스며들어 가공이 어려우며, 30을 초과하는 경우는 제직시 작업성이 불량하여 원사의 강도를 저하시켜 원단의 강도가 약하게 되고 원단의 접힘성이 불량하여 수납공간이 커지게 된다.If the coverage is less than 26, the airbag fabric lacks strength, and the coating agent penetrates between the fabrics, making processing difficult. If the coverage exceeds 30, the workability during weaving decreases the strength of the yarn due to poor workability. The strength is weak and the fabric is poor in foldability, thereby increasing the storage space.
또한 사용되는 나일론 66원사의 데니어는 400∼1,000데니어가 적당한 바, 400 미만인 경우에는 강도가 약하고 1,000을 초과하는 경우에는 너무 두꺼워져서 적합하지 않다.In addition, the denier of nylon 66 yarn to be used is suitably 400 to 1,000 denier. If it is less than 400, the strength is weak and if it exceeds 1,000, it is too thick and is not suitable.
또한 이때 사용되는 고무로서는 실리콘 고무를 사용함을 특징으로 하는데, 종래에 사용된 클로로프렌 고무와 비교시 할로겐화수소의 발생이 없어 나일론 포지가 열화되는 일이 없으며, 클로로프렌고무보다 우수한 물성을 나타낸다.In addition, the rubber used at this time is characterized in that the use of silicone rubber, compared with the conventional chloroprene rubber, there is no generation of hydrogen halide, so that nylon forge does not deteriorate, and exhibits superior physical properties than chloroprene rubber.
실리콘 고무로는 비닐기를 가진 폴리실록산을 주쇄로 하는 점도 300∼4,000포아즈의 실리콘고무를 사용하고 있는데, 점도가 300 미만인 경우에는 원단에 침투되어 물성이 떨어지며, 4,000을 초과하는 경우에는 작업성이 나쁠 뿐만 아니라 두께가 두꺼워지는 문제점이 있다.As silicone rubber, a silicone rubber having a viscosity of 300 to 4,000 poise is used as the main chain of polysiloxane having vinyl groups. If the viscosity is less than 300, the rubber penetrates into the fabric and the physical properties are poor. In addition, there is a problem that the thickness is thick.
이외에도 상기 실리콘고무 용액내에 경화제, 경화촉진제, 노화방지제, 윤활제 및 충전제 등을 첨가할 수도 있고, 도포성을 향상하기 위하여 용제를 첨가할 수도 있다.In addition, a curing agent, a curing accelerator, an anti-aging agent, a lubricant, a filler, or the like may be added to the silicone rubber solution, or a solvent may be added to improve the coating property.
