The invention discloses a
glass wool ceiling board. The
glass wool ceiling board comprises a
glass wool board layer, a
glass fiber felt layer and a plaster
coating material layer, wherein the glass
wool board layer is prepared from centrifugal glass
wool fibers with an environment-friendly resin binder, and the
mass ratio of the centrifugal glass
wool fibers, the environment-friendly resin binder and a plaster
coating material is (85-93): (7-15): (2-3). A preparation method of the glass wool ceiling board comprises the steps of uniformly spraying the environment-friendly resin binder to the surfaces of the centrifugal glass wool fibers in an atomization state, carrying out wool collection by a wool collector, compressing and conveying collected wool into a curing oven for curing so as to obtain a glass wool board, then, carrying out
glass fiber felt facing on the glass wool board, and carrying out compressed plaster
coating material spraying according to different decorative patterns. Compared with the prior art, the glass wool ceiling board and the preparation method thereof have the advantages that glass wool ceiling boards of rich and diverse forms can be prepared according to
customer requirements, and the ceiling board has heat preservation, heat insulation, sound absorption and
fire prevention effects, does not fall dust, is free from
formaldehyde release, is harmless to the health of users and is light in weight, so that the requirements on the load of a building can be lowered, and transporting and mounting are more convenient.
