Title:
PCM-APPLIED POLYURETHANE FOAM FOR CAR HEADLINING, METHOD FOR MANUFACTURING SAME, AND PCM-APPLIED POLYURETHANE FOAM-BASED CAR HEADLINING
Document Type and Number:
WIPO Patent Application WO/2020/050693
Kind Code:
A1
Abstract:
The present invention provides a phase change material (PCM)-applied polyurethane foam for a car headlining, a method for manufacturing same, and a PCM-applied polyurethane foam-based car headlining. The present invention provides a phase change material (PCM)-applied polyurethane foam for a car headlining, a method for manufacturing same, and a PCM-applied polyurethane foam-based car headlining. In the PCM-applied polyurethane foam for a car headlining, the method for manufacturing same, and the PCM-applied polyurethane foam-based car headlining according to the present invention, the temperature control of the car headlining in the high-temperature or low-temperature conditions is maximized by means of the use of the PCM-applied polyurethane foam, and especially, a PCM vacuum impregnation structure, in which PCM is placed inside pores of an open cell structure under the surface of the polyurethane foam without pore closure, maintains high air permeability, thereby enabling the smooth functioning of the PCM, and also, the placement of the PCM only inside the polyurethane foam enhances the adhesion of the surface of the polyurethane foam, thereby enabling the smooth attachment of various substances onto the surface even without an adhesive, such as a hot-melt adhesive.
