POROUS SEALING PLATE AND PREPARATION METHOD THEREFOR

Provided in the present invention are a porous sealing plate and a preparation method therefor, which belong to the technical field of sealing plates. The porous sealing plate comprises an enclosure frame, a core material, a getter and a membrane material, wherein the getter is located in the core material, and the core material has an aperture and is an inorganic powder and/or fiber; the enclosure frame has a continuous outline structure, is made of an engineering plastic, and is located at the periphery of the core material, the aperture of the core material or both the periphery and the inner aperture of the core material; the membrane material is an aluminum-plastic composite membrane, a polyimide composite membrane, a metallized membrane or an inorganic non-metal coated plastic composite membrane; and the membrane material wraps the surface of the core material. By controlling the enclosure frame structure of an engineering plastic, the free design of the appearance and the inner aperture structure of a porous sealing plate having a complex structure is achieved, a breakthrough is made to the single and unchanged structural appearance characteristic caused by vacuum sealing of a traditional porous sealing plate, the porous sealing plate can adapt to the heat preservation and heat insulation of a complex structure, and the application range thereof is widened; moreover, the flatness of the appearance or the inner aperture of the porous sealing plate is improved by the enclosure frame of the engineering plastic, and the porous sealing plate is not prone to deformation.
