AI Technical Summary
In existing technologies, nanomaterials tend to agglomerate in paper-faced gypsum board, resulting in limited improvement in flame retardant properties and strength.
Nano-silica and nano-calcium carbonate are loaded onto the surface of glass fibers, and the glass fibers are treated with γ-aminopropyltriethoxysilane and 2-hydroxy-4-(3-triethoxysilanepropoxy)benzophenone to form a pit structure. The nanomaterials are uniformly dispersed by the interaction of positive and negative charges.
It improves the flame retardant properties and mechanical strength of paper-faced gypsum board, prevents the agglomeration of nanomaterials, and further enhances the overall performance of paper-faced gypsum board.
