Abstract

The present disclosure provides a method for manufacturing a compound diaphragm. The method comprises the following steps: providing a sheet made of macromolecular material; providing damping glue; blending powdered graphene into the damping glue; and coating the damping glue blended with the graphene onto a surface of the sheet made of macromolecular material to form a compound diaphragm. The method is simple, has a low production cost, and can provide a compound diaphragm with high strength and superior performances.

Claims

1. A method for manufacturing a compound diaphragm, comprising the steps of:

Step 1;

providing a sheet made of macromolecular material;

Step 2;

providing damping glue;

Step 3;

providing and blending powdered graphene into the damping glue; and

Step 4;

coating the damping glue mixed with the graphene onto a surface of the sheet made of macromolecular material for forming a compound diaphragm.

2. The method for manufacturing a compound diaphragm of claim 1, further comprising the step of drying the compound diaphragm.

3. The method for manufacturing a compound diaphragm of claim 1, wherein the material of the macromolecular diaphragm is any of polyetheretherketone (PEEK), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS) and polyarylate (PAR).
