Abstract
The present application relates to the technical field of composite film, and more particularly, to a diaphragm composite material and a preparation method thereof. The diaphragm composite material includes a polyethylene naphthalate (PEN) film layer, an aluminum-plated film layer, an aerogel layer, and an elastic adhesive layer disposed between the PEN film layer and the aluminum-plated film layer for bonding the PEN film layer and the aluminum-plated film layer, the aerogel layer is coated on one side of the aluminum-plated film layer away from the elastic adhesive layer. The diaphragm composite layer of the present application has high strength and strong rigidity, has better vibration dampening and noise-reducing effects, and wear-resistant and corrosion-resistant effects, and is worthy of popularization.
