The invention provides a multifunctional PTC (Positive Temperature Coefficient) graphene heating skin and a preparation method thereof, and belongs to the technical field of light-transmitting coating veneers in automotive interiors. Comprising a surface layer, a pattern layer, an electrode layer, a graphene heating layer, a capacitive touch layer, a pressure layer, a second control electrode layer and a protective layer, the multifunctional PTC graphene heating skin integrates touch, pressure, display and heating, a touch function and a pressure function are combined, that is, only when a touch signal exists and a pressure signal reaches a threshold value, the touch is identified to be valid, and a corresponding function is correspondingly executed, so that no touch is effectively realized; in addition, a PTC (Positive Temperature Coefficient) electric heating function is integrated, so that the vehicle interior trim can provide comfortable hand feeling temperature for a user in winter, and the vehicle interior trim is very practical. And the atmosphere in the vehicle can be improved through the light-transmitting display function.

    本发明提供一种多功能PTC石墨烯加热表皮及其制备方法,属于汽车内饰中可透光的包覆饰面技术领域;包括表面层、图案层、电极层、石墨烯加热层、电容触控层、压力层、第二控制电极层和保护层;该多功能PTC石墨烯加热表皮,集触摸、压力、显示及加热于一体,其中触摸功能与压力功能结合,即只有当触摸有信号且压力信号达到阈值时,才会识别本次触摸有效,并对应执行相应的功能,有效方式了无触碰;除此之外,还集成了PTC电加热功能,使得在冬季车辆内饰也能为使用者提供舒适的手感温度,极为实用。透光显示功能还能提升车内的氛围。
