Abstract

The invention discloses a skin core structure tombarthite strontium aluminate long afterglow luminescent fiber and preparation method thereof, by mass, the luminescent fiber is prepared from 70-85% of core layer, and 15-30% of skin layer; the core layer is prepared from 10-30% of tombarthite strontium aluminate luminescent powder, 0.02-0.05% of phosphite ester, 0.02-0.2% of antioxidant agent, 0.5-1% of silane coupling agent, the balance polyamide resin; the skin layer adopts the transparent polymethyl methacrylate, or polycarbonate or polystyrene resin with added toughening agent. The prepared luminescent fiber because of the tombarthite strontium aluminate luminescent material being all located on the core layer, effectively prevents the tombarthite strontium aluminate luminescent material from falling, ensures the luminescent brightness of fibers, and raises the water resistance and abrasion resistance of the luminescent fibers, meanwhile the skin layer adopts resins with excellent transparent degree, making the prepared luminescent fibers smooth on surface, and further enhancing the luminescent effect of the luminescent fibers.

Description

technical field [0001] The invention belongs to the technical field of functional fibers, and in particular relates to a preparation method of a rare earth strontium aluminate long-lasting luminescent fiber with a skin-core structure. Background technique [0002] Rare earth luminescent material is a functional and environmentally friendly new material made of rare earth luminescent materials. It is an important light-to-light conversion energy-saving material, that is, rare earth luminescent materials absorb energy from the outside, and then store the absorbed energy through electronic transitions. , glows continuously in the dark. Because the quantum conversion rate of aluminate rare earth luminescent materials is as high as 90%, it only needs sunlight or light for 10 minutes, and can continue to emit light for more than 10 hours. Therefore, rare earth aluminates are currently the main commercial luminous materials. [0003] At present, luminescent fibers are mainly made ...
