Abstract

The invention discloses a temperature-resistant vibration reduction sealing washer and an automobile air conditioner with the same. The temperature-resistant vibration reduction sealing washer comprises an ethylene-propylene-diene monomer (EPDM) rubber closed-hole foaming sheet layer and an expanded perlite micro-powder high-temperature-resistant heat-insulating paint layer, and the single side of the EPDM rubber closed-hole foaming sheet layer is arranged on the expanded perlite micro-powder high-temperature-resistant heat-insulating paint layer. By means of the above manner, the temperature-resistant vibration reduction sealing washer has excellent performance of heat preservation, sealing, gas leakage prevention, heat insulation, aging resistance, long service life, good washer rebound resilience, vibration reduction, shock prevention, noise reduction and the like, an automobile air conditioner abnormal-shape pipe is not prone to breakage, travelling is safer and more comfortable, the number of maintenance times of the automobile air conditioner abnormal-shape pipe is smaller, the maintenance cost is saved for customers, and automobile quality is improved.

Description

technical field [0001] The invention relates to a temperature-resistant and vibration-reducing sealing gasket and an automobile air conditioner with the sealing gasket. Background technique [0002] Since the shape design of modern cars is mostly composed of beautiful curved surfaces, the layout of the air-conditioning air supply duct system of the car also changes accordingly according to the curved surface. Space, giving people a comfortable, low-noise, low-vibration interior effect, for which the innovative design of the automotive air-conditioning piping system. [0003] If the existing sealing gaskets on the market are applied to the special-shaped interface, the sealing of the interface will be unreliable, and it will not be able to reduce the vibration generated by the driving of the car and the pulsating vibration of the airflow in the air duct, which will lead to the short life of the plastic gas pipeline. , easy to break, making the driving safety and comfort not ...
