Abstract
The invention discloses heating slurry with antibacterial and heat dissipation functions, which comprises the following raw materials in parts by weight: 50-65 parts of graphene, 2-10 parts of graphite alkyne, 2-10 parts of boron alkene nanosheets, 2-10 parts of boron nitride nanosheets, 35-60 parts of water-based resin, 0.1-1 part of wetting agent, 20-40 parts of dispersing agent, 0.1-1 part of anti-settling agent, 0.1-1 part of cosolvent, 0.1-1 part of film forming agent, 0.1-1 part of defoaming agent, 1-3 parts of curing agent and 100-200 parts of deionized water. The heating slurry with the antibacterial and heat-dissipating functions solves the problems of complex preparation process and poor stability of materials in the prior art, is easy to operate, is suitable for mass production in factories, and has a wide application range.
Description
Technical Field
The invention belongs to the technical field of preparation of environment-friendly slurry, and particularly relates to heating slurry with antibacterial and heat dissipation functions.
Background
In recent years, the two-dimensional carbon material has been developed at a high speed, and has become a research hotspot and a leading direction of the current functional material internationally.
