Study Of The Process Of Melamine Formaldehyde Resin Fibers

This thesis investigated the polymerization process of melamine and formaldehyde after referring to a great deal of domestic and foreign documents. Some thermoplastics have been used to modify melamine-formaldehyde resin solution and BPC-17 resin was selected as fiber-shaped agent finally. The effect of two stabilization agents to the resin solution was studied, at last boric acid was chosen, and then, its stabilization mechanism was speculated. The filature equipment was designed and its parts were manufactured after confirming the lab preparation route of the filature resin solution. After being installed and debugged, the equipment was used to spin the filature resin into firstborn fiber. Some series of firstborn fibers were solidified, and then, they were characterized through IR, XRD, DTA, TG. The result showed the top using temperature of the solidified fibers reach 370℃. The solidified fibers were dealt and their mechanics performance and heat-resistance were tested, the result showed after 3h at 160℃, the mechanics performance of fibers prove to be the best, their LOI are about 34, but their elongation ratio are only 2%~3%, they have to be improved.
