摘要: A wet fiber based composition that includes wet glass fibers, a water dispersible polymeric resin, and gypsum is provided. Components including melamine formaldehyde, a filler material, coupling agents, acetic acid, an accelerator, and/or a hardener may also be added to the composition. The gypsum may be a-gypsum, ß-gypsum, or combinations thereof. The wet glass fibers are wet chopped glass fibers or a wet continuous roving. The combination of the wet glass fibers, the water dispersible polymeric resin, and the gypsum have a synergistic effect that creates a composite product that is water resistant, fire resistant, and has improved mechanical properties. In one exemplary embodiment, the wet fiber based composition is used to form a gypsum board that can be molded into various composite products. In other exemplary embodiments, thin multi-ply gypsum boards may be formed by alternately layering glass mats with layers of a gypsum/polymer slurry.
