Problems solved by technology

The main advantage is that the physical properties of the fiber are less affected by the fact that the fluorescent substance does not enter the fiber body, and the selection of the fluorescent substance is not limited by high temperature. There are equipment, certain temperature and chemical reagents, etc., and the manufacturing process is more complicated. In addition, the surface coating method is easy to cause the coating to fall off.

Abstract

The invention discloses a white graphene fluorescent fiber and a preparation method thereof. The preparation method comprises the steps that step 1, resin powder is taken and added into a solution; step 2, white graphene powder is added into the resin powder, a first additive is added, and stirring is carried out; step 3, a dispersing agent is added for being continuously stirred; step 4, a second additive is added into fluorescent powder, heating and stirring are carried out; step 5, the fluorescent powder mixture obtained in the step 4 is added into the mixture obtained in the step 3, and stirring is carried out while the temperature is kept to obtain a spinning solution; step 6, heat preservation and standing are carried out on a spinning stock solution, and vacuumizing is carried out to remove bubbles to obtain a spinning solution; step 7, the spinning solution is sucked into an injector for spinning; and step 8, process parameters are set, and uniform and continuous fluorescent fibers are prepared. The invention further provides the white graphene fluorescent fiber prepared by the method. The fluorescent fiber is better in fluorescent effect, more stable and long in service life, and further has the advantages of being excellent in mechanical property, not prone to being broken and the like.

Description

technical field [0001] The invention relates to a white graphene composite functional fiber and a preparation method thereof, in particular to a white graphene fluorescent fiber and a preparation method thereof. Background technique [0002] The chemical name of white graphene is hexagonal boron nitride (h-BN). It is the only boron nitride phase that exists in nature. It belongs to the hexagonal crystal system and is white in color. It has layered structure characteristics and lattice similar to graphene. parameters, so it is also called white graphene. It has excellent high temperature resistance, thermal stability, corrosion resistance and other characteristics. In addition, the luminescence of h-BN can be used as an electroluminescent material. [0003] The fluorescent material is calcined by combining metal sulfide or rare earth oxide with a small amount of active agent. Colorless or light white, under the irradiation of ultraviolet light (200-400nm), it will show var...
