FLAME-RETARDANT FLOOR DECORATION MATERIAL AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a flame-retardant floor decoration material comprising a lower layer, a base layer, a print layer, and a transparent layer, which are in order from bottom to top, wherein at least one of the layers contains a polyvinyl acetal resin. In addition, the present invention relates to a method for preparing a flame-retardant floor decoration material comprising a lower layer, a base layer, a print layer, and a transparent layer, which are in order from bottom to top, wherein the method comprises: (1) a lower layer preparation step for preparing a lower layer using a composition containing 100 parts by weight of a polyvinyl acetal resin and 100-400 parts by weight of a filler; (2) a base layer preparation step for preparing a base layer composed of a glass fiber immersed in a PVC sol; (3) a printing step for forming a print layer by printing the print layer on the base layer or binding a print pattern-printed film or paper to the base layer; (4) a transparent layer preparation step for preparing a transparent layer composed of a transparent PVC film or a PET film; and (5) a binding step for binding the layers such that the base layer with the print layer formed thereon is disposed between the lower layer and the transparent layer.
