Abstract
The invention relates to a waterproof ventilated membrane for car light. The waterproof ventilated membrane is formed by compounding of three layered structures and comprises a fabric layer, a waterproof ventilated layer and a bonding layer which is arranged between the above fabric layer and the waterproof ventilated layer and is used for connecting the fabric layer and the waterproof ventilated layer. The invention solves defects existing in the prior art. According to the waterproof ventilated membrane for car light, a fabric material and an expanded polytetrafluoroethylene film undergo compounding, laminated water resistance and oil resistance processing so as to obtain a multifunctional high-molecular material, thus endowing the expanded polytetrafluoroethylene film with better strength, waterproofness, permeability, oleophobic performance, long life, weldability and the like and maintaining internal and external pressure balance. The waterproof ventilated membrane can be used to raise reliability of many automobile parts, including parts of a car light, an engine controller/anti-lock braking system module, a sensor, a connector, an electric car window motor, a fuel system and the like, and is applied in automobile and heavy trucks. Air exchange can be carried out rapidly according to the pressure variation generated by temperature change, and vehicles can be protected from being polluted by water, automobile discharged fluids and dust.
