The temperature control function of the vehicle headlining is maximized in low temperature conditions, and in particular, the high air permeability is maintained by the PCM vacuum impregnation structure in which the PCM is disposed without closing the pores in the open cell structure under the polyurethane foam surface. PCM applied poly for vehicle headlining where PCM functions smoothly and PCM is placed only inside the polyurethane foam to improve adhesion of the surface of the polyurethane foam so that adhesion of various materials on the surface is smooth without adhesive materials such as hot melt.

차량용 헤드라이너(head liner)는 자동차의 실내 천정에 설치되어 외부로부터 차량의 실내로 유입되는 소음이나 진동을 차단하고, 차량 내부나 외부의 열 전달을 차단하는 단열성의 향상을 위해 다양한 층의 적층 구조로 이루어진다.Vehicle head liner is installed on the indoor ceiling of a vehicle to block noise or vibration from entering the vehicle interior from the outside, and stacked in various layers to improve heat insulation to block heat transfer inside or outside the vehicle Is made of
일반적으로 차량은 사방이 유리로 둘러싸여 있어 여름철에는 열기가 실내로 유입되고 겨울철에는 냉기가 실내로 유입되기 쉬운 구조이다.In general, the vehicle is surrounded by glass on all sides, so heat is introduced into the room during the summer and cold air is easily introduced into the room during the winter.
여름철 차량의 실내 온도는 부품별로 차이가 나지만 시트의 경우 70 ~ 80℃ 까지 상승하고, 겨울이면 외기 온도와 동일 수준으로 내려간다. 이렇게 차량 내부의 여름철 뜨거운 느낌과 겨울철 차가운 느낌을 감소시키기 위하여 통풍시트와 열선시트가 있다. 그러나, 홈이 뚫려 있는 통풍시트의 경우에는 이물질이 들어가게 되어 오염 및 부식이 발생하여 차량내부의 냄새나 위생상의 문제가 발생할 수 있다. 차량용 시트의 감성품질은 색상, 촉감 뿐만 아니라 여름철 상승한 고온의 시트와 겨울철 차가운 시트로 인한 온도 문제도 크게 부각되고 있다.In the summer, the interior temperature of the vehicle varies by part, but in the case of the seat, it rises to 70 ~ 80 ℃, and in winter, it goes down to the same level as the outside temperature. In order to reduce the hot feeling in the summer and the cold feeling in the winter, there are ventilation seats and heated seats. However, in the case of a ventilated sheet having a grooved hole, foreign matter may enter and cause contamination and corrosion, which may cause odor or hygiene problems in the vehicle. The emotional quality of the car seat is not only color and touch, but also the temperature problem due to the high temperature seat in the summer and the cold seat in the winter.
특히 대부분의 외부가 금속 강판으로 제조되는 차량은 여름철에 밀폐 상태로 보관되는 경우 내부 온도가 급격히 올라갈 수 있다. 이러한 온도 상승을 방지하기 위해 유리에 필름을 붙이거나 코팅하여 외부 열기의 실내 유입을 차단하는 방법을 사용하고 있으나, 차량의 넓은 면을 차지하는 루프 패널을 통해 들어오는 열기를 차단할 수 있는 기술이 필요하다. 이에 따라 대한민국 등록특허공보 등록번호 제10-1786700호 "차량용 헤드라이너", 등록번호 제10-1692861호 "열 차단 기능을 가진 자동차용 헤드 라이닝 및 그 제조방법" 등의 기술이 안출되었는데, 상기 "차량용 헤드라이너"는 열 차단 물질이 코팅되어 형성된 열 차단층을 구비함으로써 헤드라이너의 열차단 성능을 향상시킨 기술이며, 상기 "열 차단 기능을 가진 자동차용 헤드 라이닝 및 그 제조방법"은 열 차단 물질을 첨가한 핫멜트 필름을 부착함으로써 헤드 라이닝에서 루프패널을 통해 자동차 실내로 전달되는 열을 차단할 수 있게 한 기술이다.In particular, when most of the exterior is made of a metal steel plate, the internal temperature may increase rapidly when stored in a closed state during the summer. In order to prevent such a rise in temperature, a method is used to block indoor heat from entering the outside by attaching or coating a film on the glass.

The PCM 120 is sprayed while moving. Through this, the PCM 120 is uniformly dispersed in the width direction w of the upper surface of the polyurethane foam 110 to prevent the PCM 120 from being concentrated in a specific area.
