The invention provides a composite technique for membrane filter material and an equipment. Polytetrafluoroethylene membrane and glass fiber base cloth are synchronously input between the heating roller and the press roller of a composite equipment at a speed ranging from 3 to 5m per min, and the polytetrafluoroethylene membrane is input in the direction of the tangent between the heating roller and a lower press roller and is formed by hot pressing with a linear pressure ranging from 15 to 30kN/m at the temperature ranging from 260 to 360 DEG C; after the membrane filter material formed by the hot press is heated by the one-fourth surface of the heating roller and then is formed by hot pressing with a linear pressure ranging from 15kN/m to 20kN/m. The technique method realizes rubber-free hot pressing compounding of the polytetrafluoroethylene membrane and the glass fiber base cloth, thus effectively saving the original physical and chemical property of the polytetrafluoroethylene membrane, enhancing the permeability and filtration efficiency of the membrane filter material, strengthening the composite strength of the membrane filter material and extending the service life of themembrane filter material; simultaneously, the hot pressing composite equipment has reasonable structure, thus ensuring the production and preparation of the membrane filter material.
