Description
본 발명은 자동차의 스티어링 휠용 도료 조성물에 관한 것으로서, 더욱 상세하게는 기존의 스티어링 휠에 적용되었던 우레탄 도료에 고경도 재료인 가넷 미세분말과 각종 첨가제를 함유시킴으로써, 기존의 도료 조성물에 비해 마찰 계수가 높기 때문에 운전 시, 운전자의 손과 스티어링 휠 표층 사이의 마찰력을 증가시켜 미끄럼을 방지할 수 있도록 개선된 자동차의 스티어링 휠용 도료 조성물에 관한 것이다. The present invention relates to a coating composition for a steering wheel of an automobile, and more particularly, by containing a high-hardness garnet fine powder and various additives in a urethane coating applied to a conventional steering wheel, a friction coefficient is higher than that of a conventional coating composition. It relates to a coating composition for a steering wheel of a vehicle, which is improved to prevent slipping by increasing friction between the driver's hand and the steering wheel surface layer when driving.
일반적으로, 스티어링 장치(steering system)란 자동차의 진행 방향을 변경하기 위해 사용되는 장치로 스티어링 휠, 스티어링 축 및 컬럼 등으로 이루어진 조작기구, 워엄 섹터형, 워엄 섹터롤러형, 볼너트형, 가변 기어비형, 래크 피니언형 등의 스티어링 기어기구 및 피트먼 아암, 스티어링 링크, 스티어링 너클 등으로 이루어진 링크기구로 구성되어 스티어링 휠의 회전을 스티어링 기어를 통하여 구동휠로 전달하는 기계식의 스티어링 장치와, 조작력 경감을 위하여 동력 실린더를 사용하는 파워 스티어링(Power Steering)방식이 사용되고 있다.In general, a steering system is a device used to change the direction of travel of a vehicle. An operating mechanism consisting of a steering wheel, a steering shaft, and a column, a worm sector type, a worm sector roller type, a ball nut type, and a variable gear ratio Mechanical steering device which consists of steering gear mechanisms such as type and rack pinion type, and link mechanisms composed of Pitman arm, steering link, steering knuckle, etc. to transmit the rotation of the steering wheel to the driving wheel through the steering gear, and to reduce operation force For this purpose, a power steering method using a power cylinder is used.
여기서, 상기 스티어링 휠(10)은 도 2에 도시된 바와 같이, 단면을 기준으로 내부에는 보강재로서, 탄소강재(STKM)로 된 파이프(11)가 있으며, 그 위에 운전자의 촉감 향상용으로 우레탄 및 PVC foam재(12)가 덮고 있다. Here, as shown in Figure 2, the steering wheel 10, as a reinforcement on the basis of the cross section, there is a pipe 11 made of carbon steel (STKM), thereon urethane and for improving the driver's touch The PVC foam material 12 is covered.
이러한 우레탄 혹은 PVC 경화 시, 가장 바깥 부분이 열에 의해 우레탄 및 PVC표층(13)을 형성하며, 현재 주위부품과의 색상 조화를 위하여 주변 부품과 동일한 색상을 우레탄 및 PVC표층(13)위에 도장을 하고 있다. When the urethane or PVC is cured, the outermost part forms the urethane and PVC surface layer 13 by heat, and paints the same color on the urethane and PVC surface layer 13 as the peripheral parts for color harmony with the current peripheral parts. have.
종래의 스티어링 휠은 우레탄 및 PVC 표층에 단순히 외관미의 향상 및 주변과의 색상조화를 위하여 2액형 우레탄 도장을 하고 있다. Conventional steering wheel has a two-component urethane coating on the urethane and PVC surface layer simply to improve the appearance and color coordination with the surroundings.
이러한 도장면을 가진 스티어링 휠은 운전자의 땀이나 습기로 인하여 미끄럼을 발생시키기 쉬우며, 특히 경질 PVC를 휠의 재료로 적용할 시에는 이런 문제점이 더욱 부각된다. The steering wheel having such a painted surface is easy to generate slip due to sweat or moisture of the driver, especially when the rigid PVC is applied as the material of the wheel.
일부 차종에서는 외관미의 향상과 미끄럼을 방지하기 위하여 표층에 미세한 엠보싱 처리를 하기도 하지만, 이 자체가 재료의 마찰력을 증대시켜 주기에는 한계가 있는 문제점이 있다. In some models, fine embossing is applied to the surface layer in order to improve appearance and prevent slippage, but there is a problem in that it increases the frictional force of the material.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 운전자의 손에 의한 마모를 방지할 수 있도록 하기 위해 고경도 재료이고 도장 후에 색상 변화가 없도록 입자의 크기가 일정 크기 이하로 미세하여야 하며, 마찰력을 증대시킬 수 있는 물성을 가지는 재질로서, 도장하고자 하는 도막의 두께에 대해 약 60% 크기의 입도를 가지는 입자가 전체 입자 중에 약 60% 이상 함유되어 있는 미세분말을 우레탄 도료에 첨가하게 되면 물성이 우수하고, 마찰력이 향상된다는 사실을 알게되어 본 발명을 완성하였다. Therefore, the present invention has been made to solve the above problems, in order to prevent wear by the hand of the driver is a high hardness material and the size of the particles should be fine to a certain size or less so that there is no color change after coating. In addition, it is a material having physical properties that can increase the frictional force, so that the particles having a particle size of about 60% with respect to the thickness of the coating film to be coated are added to the urethane paint with fine powder containing about 60% or more of the total particles. When the physical properties are excellent, the friction force is improved to complete the present invention.
따라서, 본 발명은 경도가 높고, 색상의 변화가 없으며, 마찰계수가 높아 미끄럼을 방지할 수 있는 자동차의 스티어링 휠용 도료 조성물을 제공하는데 그 목적이 있다.

About 60% or more of the particle size compared to the thickness may be added in the particle to increase the frictional force, thereby preventing slippage.
본 발명에서 사용되는 가넷 미세분말의 입자 크기가 7㎛를 초과하면 가넷 고유의 색상인 자두색 빛이 남고, 도막 두께 대비, 완성 도막으로부터 입자 이탈에 의한 도막 손상이 유발되는 문제점이 있다. When the particle size of the garnet fine powder used in the present invention exceeds 7㎛, the purple light, which is a garnet inherent color, is left, and there is a problem in that the coating film is damaged due to particle detachment from the finished film in comparison with the coating film thickness.

This difficult and color development of the fine powder itself causes color differences with surrounding parts, making it difficult to apply.

상술한 바와 같이, 본 발명에 따른 자동차의 스티어링 휠용 도료 조성물은 운전 시, 스티어링 휠과, 손 또는 장갑면의 미끄럼을 방지할 수 있고, 첨가되는 가넷 미세분말은 연마제 제조 시에 공정상 남는 재료로서 저가의 재료이며, 고경도의 미세분말이므로 장기간의 내구성능을 지니는 효과가 있다. As described above, the coating composition for the steering wheel of the vehicle according to the present invention can prevent the sliding of the steering wheel, the hand or the glove surface during driving, and the added garnet fine powder is a material remaining in the process during the manufacture of the abrasive It is an inexpensive material and has a long-term durability since it is a high hardness fine powder.
도 1은 본 발명에 따른 자동차의 스티어링 휠을 나타내는 부분 종단면도이고,1 is a partial longitudinal cross-sectional view showing a steering wheel of a vehicle according to the present invention,
도 2는 종래의 자동차의 스티어링 휠을 나타내는 횡단면도이다. 2 is a cross-sectional view showing a steering wheel of a conventional vehicle.
