  • Membrane and method for producing diaphragm, and composite diaphragm
    Patent number: 9635464
    Abstract: A membrane and a method for producing a diaphragm, and a composite diaphragm are provided. The MCPET material is a MCPET baffle with micropores independent from each other; wherein an average size of the micropore is smaller than or equal to 5 ?m, a foaming rate of the MCPET baffle is less than 2 times, and a density of the MCPET baffle is less than 300 kg/m3. The MCPET baffle is further processed by means of layered cut to form the membrane that is thinner than the MCPET baffle. At least one surface with micropores is exposed to form a micropore exposed surface. The membrane is heated under a temperature of 130-140° C. to form the diaphragm. The composite diaphragm includes a main diaphragm and an auxiliary diaphragm, wherein the main diaphragm is made of the membrane of the present application. The diaphragm made of the membrane has a superior sound performance.
