METHOD FOR PREPARING ENVIRONMENTALLY FRIENDLY, FLAME RETARDANT, AND HIGHLY FUNCTIONAL POLYESTER, NYLON, AND NATURAL FIBERS USING POLYMERIZATION CHIPS OF SILICA-CONTAINING ORE |
摘要 |
The present invention provides a method for preparing silica polymerization chips, comprising the steps of: (a) mixing a silica nanopowder of 0.2-0.4 mum changed by combustion and maturation and a coating solution for making the rough surface of the nanopowder to be smooth by coating, so as to coat the surface of the nanopowder and to form a slurry type; (b) mixing the nanopowder mixture and powder-type terephthalic acid; (c) storing and drying the mixture to dry the mixture and to remove moisture; (d) forming a polymer of the nano-mixture and terephthalic acid by the polymerization of the mixture in which terephthalic acid mixed in the mixture is melted by polymerization so as to be fused with the nano-mixture; and (e) extruding and cooling a molten product in which polymerization-completed terephthalic acid is melted after step (d), and cutting the same into a pellet form so as to prepare silica polymerization chips. |
