| titleOfInvention | A kind of green charcoal source copolymerization flame-proof polylactic acid fiber and preparation method thereof |
| abstract | The invention provides a kind of green charcoal source copolymerization flame-proof polylactic acid fiber and preparation method thereof.Described green charcoal source copolymerization flame-proof polylactic acid fiber includes：The first step：Prepare the green flame-retardant modified function monomer in charcoal source (FR)；Second step：In a vacuum or inert atmosphere, with Sn (Oct) 2 For catalyst, the green flame-retardant modified function monomer in charcoal source and lactide (LA) are obtained into green charcoal source copolymerization flame-proof polylactic acid (FR PLA) at 130 DEG C~170 DEG C through ring opening copolymer reaction；3rd step：Green charcoal source copolymerization flame-proof polylactic acid is dried, makes its moisture content≤80ppm, melt-spun shaping obtains green charcoal source copolymerization flame-proof polylactic acid fiber at 200 DEG C~240 DEG C.Present invention effectively prevents the problems such as fire retardant toxicity is big and fire retardant is with matrix poor compatibility, migration, precipitation, multiple melt-processed thermostability difference, gained FR PLA have good spinnability and fire resistance concurrently. |
