The invention discloses a method for preparing a composite plate by recycling bag type dust remover waste filter bags; the waste filter bags are successively subjected to crushing, cleaning, drying, shredding, mixing of glass fibers and the crushed opened material, acupuncture composite, high-temperature pressing, cooling and design finalizing, and finished product composite plate obtaining. Compared with the prior art, produced building templates and wall partition plates have no high requirements on a cleaning process and can be covered with cement and the like on the outside during the using process, so that no requirement exists for building remaining cement or lime compositions; with recycling of the waste filter bag resources, secondary pollution caused by landfilling, incineration and other processing methods is effectively solved, so as to contribute to resource re-utilization, energy saving, emission reduction and other works; in the high-temperature pressurization process, thermoplastic fibers are dissolved to play a bonding effect, so that a glue and other binders are replaced, and produced boards do not contain formaldehyde, the glue and other harmful substances and belong to green environmental-protection building materials.
