Heat insulation headlining and heat insulation system for vehicle

Abstract

The invention discloses a heat insulation headlining and heat insulation system for a vehicle. The heat insulation system comprises sheet metal and the heat insulation headlining, and the heat insulation headlining comprises a substrate layer; a first reinforcement layer is arranged on the surface, close to the indoor side of the vehicle, of the substrate layer, and a second reinforcement layer isarranged on the surface, close to the outdoor side of the vehicle, of the substrate layer; the surface of the side, opposite to the substrate layer, of the second reinforcement layer is provided withan airtight aluminum-plated nonwoven fabric layer with a heat insulation function, and a fabric layer is arranged on the surface of the side, opposite to the substrate layer, of the first reinforcement layer; and an air layer is arranged between the sheet metal and the heat insulation headlining, and the sheet metal, the heat insulation headlining and the air layer form the airtight heat insulation system. The heat insulation system for the vehicle blocks heat outside the vehicle into the air layer between the headlining and the sheet metal, meanwhile, the aluminum-plated nonwoven fabric layer has the effect of blocking air, and thus the heat conducted into a passenger compartment is greatly reduced; and the heat insulation headlining and the heat insulation system have the advantages ofbeing simple in structure, easy to achieve and good in heat preservation and insulation effect.

Description

technical field [0001] The invention belongs to the technical field of automotive interior parts, and in particular relates to a heat-insulating roof and a heat-insulating system for an automobile. Background technique [0002] The car roof is installed on the top of the car, which can play the role of heat insulation, sound insulation and beautification. In the era of more and more pursuit of high performance, environmental protection and energy saving, the interior of the car, like the appearance of the car, has become an important factor for people to choose a car. [0003] The heat insulation of the car roof refers to blocking the external heat in summer to prevent the temperature inside the car from being too high, and maintaining the temperature inside the car in winter to prevent the temperature inside the car from dissipating too quickly. In recent years, people's requirements for improving the thermal insulation performance of car roofs are particularly prominent, ...
