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.
