Problems solved by technology

[0008] Due to the uneven mixing of polyester chips or polyester chip graphene and polyester chips or crushed materials (larger particle size) of polyester chips, the spinning effect is not good, the filaments are easy to break, the product qualification rate is low, the spinning process is difficult to control, and there are sticking machines. Phenomenon, and polyester chips are easy to oxidize

Embodiment 1

[0067] A method for doping graphene in a PE substrate, comprising the steps of:

[0068] (1) Get 1kg PE base material, pulverize, obtain the particle that average particle diameter is 100 μ m, add the graphene powder of 1000g wherein, mix uniformly, obtain mixed pulverized material;

[0069] (2) In addition, 10kg of PE substrates were taken and pulverized to obtain particles with an average particle diameter of 2mm;

[0070] (3) Mix the mixed pulverized material in step (1) with the pulverized material in step (2).

[0071] Subsequently, the material obtained in step (3) can be melted, extruded and granulated to obtain a functional masterbatch.

[0072] Or, the material obtained in the step (3) is melted, and then made into a desired shape product.

Abstract

The present invention relates to a method for doping graphene in a substrate. The method comprises the following steps: (1) mixing graphene with a first substrate to be doped to obtain a mixed pulverized material; (2) mixing step (1) ) The mixed pulverized material is mixed and dispersed with the pulverized material of the second base material to be doped; the particle size of the mixed pulverized material is less than 1 mm. In the substrate doped with graphene of the present invention, the distribution of graphene is uniform, the thermal stability of the substrate is improved, the occurrence of machine sticking phenomenon is avoided, and the machine sticking phenomenon is avoided.

Description

technical field [0001] The invention belongs to the field of preparation of graphene composite materials, and in particular relates to a method for doping graphene in a substrate, and the substrate may be a polymer substrate available in the art. Background technique [0002] Graphene is a two-dimensional crystal with only one layer of atomic thickness stripped from graphite materials and composed of carbon atoms. It is the thinnest, strongest, and strongest new type of nanomaterials found so far. Adding graphene to polyester and other substrates is expected to endow the substrate with new properties, especially adding biomass graphene with antibacterial and low-temperature far-infrared functions, and the substrate is expected to have antibacterial and low-temperature far-infrared functions. [0003] However, the solid state of graphene is easy to agglomerate and form larger particle aggregates. When it is added to polyester and other substrates, it is extremely difficult to...
