Abstract

The invention discloses an in-situ polymerized modified hexagonal boron nitride nylon composite slice and a preparation method thereof. The composite slice comprises the following raw materials: 80%-90% of caprolactam, 5%-10% of deionized water, 0.1%-10% of hexagonal boron nitride and 0.1%-1% of a modifier. The invention also provides the preparation method of the in-situ polymerized modified hexagonal boron nitride nylon composite slice, which comprises the following steps: step 1, preparing modified hexagonal boron nitride slurry: adding hexagonal boron nitride sheet powder and the modifierinto deionized water, stirring, heating, and carrying out ultrasonic dispersion treatment; step 2, preparing caprolactam/modified hexagonal boron nitride slurry: adding caprolactam into the modified hexagonal boron nitride slurry, and uniformly stirring and mixing; and 3, carrying out a polymerization reaction to obtain the in-situ polymerized hexagonal boron nitride nylon slice. The composite slice prepared by the invention has anti-bacterial, far-infrared and anti-ultraviolet properties, hexagonal boron nitride in the composite slice is uniformly dispersed and is not easy to fall off, and the function is durable.

Description

technical field [0001] The invention relates to a nylon composite slice and a preparation method thereof, in particular to an in-situ polymerization-modified white graphene nylon composite slice and a preparation method thereof. Background technique [0002] "White graphene" is an alias for the nano-flakes obtained after exfoliation of hexagonal boron nitride (English name Hexagonal Boron Nitride, abbreviated as h-BN) whose grains are lamellar structures. Since the structure of hexagonal boron nitride is very similar to that of graphite, it has a hexagonal layered structure, soft texture, strong machinability, and white color. Corresponding to graphene, so hexagonal boron nitride is called "white graphene". [0003] Both hexagonal boron nitride and graphene are layered two-dimensional materials with a thickness of only one atom. , Covalent bonding between heteroatoms of nitrogen. [0004] The highly similar crystal structure gives white graphene and graphene some common c...
