Light-weight vehicle door waterproof membrane component with heat preservation, sound insulation and noise reduction capabilities and preparation process thereof

Abstract

The invention discloses a light-weight vehicle door waterproof membrane component with heat preservation, sound insulation and noise reduction capabilities and a preparation process thereof. The waterproof membrane component comprises an XPE foamed sheet layer and an adhesive layer, wherein the XPE foamed sheet layer is connected with the inner side of a vehicle door through the adhesive layer. The preparation process of the light-weight vehicle door waterproof membrane component with heat preservation, sound insulation and noise reduction capabilities comprises the following steps: carrying out plastic molding on the raw material of an XPE foamed sheet; carrying out die cutting molding, and removing burrs; coating an adhesive on the surface of the XPE foamed sheet, and baking the surface of the XPE foamed sheet; compounding release paper on the adhesive surface; and carrying out check until the quality is qualified, thereby completing the preparation of the waterproof membrane component. Through the mode, the light weight of a vehicle is favorably realized, a better space is supplied for vehicle passengers, and the light-weight XPE foamed material is used for reducing noises in the vehicle, preserving heat, preventing water and reducing vibration, so that the vehicle passengers have better comfortable feeling, the degree of fatigue is relieved, and the driving safety is further facilitated.

Description

technical field [0001] The invention relates to a lightweight car door waterproof membrane component with thermal insulation, sound insulation and noise reduction capabilities and a preparation process thereof. Background technique [0002] Most of the noise inside the car is transmitted from the door to the car. The waterproof membrane inside the car door and the sheet metal door have a certain sound insulation performance, and the noise in some cars can reach 80dB~85dB. How to reduce the intensity of the noise introduced from the door into the car is worthy of innovative research. [0003] The existing method is to use plastic films such as PE, PVC, and EVA with increased thickness and gram weight on the inner side of the car door. Although it can prevent rainwater from protecting the electrical appliances, it also reduces the noise absorption in the car, which increases the noise of the car itself. Weight, PE, PVC, EVA and other plastic films have poor thermal insulation...

Problems solved by technology

[0003] The existing method is to use plastic films such as PE, PVC, and EVA with increased thickness and gram weight on the inner side of the car door. Although it can prevent rainwater from protecting the electrical appliances, it also reduces the noise absorption in the car, which increases the noise of the car itself. Weight, PE, PVC, EVA and other plastic films have poor thermal insulation properties and have no ability to absorb sound and reduce noise
