The invention relates to a halogen-free flame-retardant hybrid fiber yarn fabric laminated board and a preparation method thereof, the laminated board is obtained by alternately laminating hybrid fiber yarn fabric and polypropylene halogen-free flame-retardant sheets, the outermost layer of the laminated board is a polypropylene halogen-free flame-retardant sheet, and the ratio of the hybrid fiber yarn fabric to the polypropylene halogen-free flame-retardant sheet is 1: 1 or 2: 1, alternately laminating, and preparing the laminated plate by adopting a hot-press forming process. Compared with the prior art, the invention restrains the 'wick effect' and has excellent dimensional stability and mechanical property. |
