Abstract

The invention belongs to the technical field of graphene coatings, in particular to an antistatic graphene coating and a preparation method thereof, and in particular to the antistatic graphene coating which is prepared from the following components in parts by weight: 7-15 parts of graphene powder; 24-32 parts of terpene resin; 16 to 28 parts of epoxy-terminated modified polyurethane resin; 4-9 parts of sodium polyphosphate; 2-5 parts of zirconium silicate; 3-6 parts of vanadium diboride; 2-5 parts of Arabic gum; 2-6 parts of cyclodextrin; 1-5 parts of cetyl alcohol, 3-6 parts of sodium benzoate, 4-8 parts of nano attapulgite, 1-4 parts of dimethyl dimercaptoacetic acid isooctyl ester tin, 3-7 parts of magnesium sulfate, 4-9 parts of butylated hydroxyanisole, 1-5 parts of an isobutyltriethoxysilane coupling agent, 2-6 parts of gamma-mercaptopropyltrimethoxysilane, 4-7 parts of leveling agent and 60-100 parts of a solvent. The surface resistance of the graphene coating is lower than 8* 10 < 3 > ohm, and the graphene coating is good in antistatic property, high in hardness, strong in adhesive force, high in impact strength, scratch-resistant, long in service life and good in comprehensive performance; meanwhile, the preparation process is simple, low in manufacturing cost and suitable for general application and popularization.

Description

technical field [0001] The invention belongs to the technical field of graphene coatings, in particular to an antistatic graphene coating and a preparation method thereof. Background technique [0002] Graphene is widely used in integrated circuits, transistors, thermal conductive materials / thermal interface materials, supercapacitors, energy storage materials, Antibacterial materials, reinforcing materials, anti-corrosion coatings and other fields have been widely used. [0003] Static electricity is a phenomenon of charge accumulation due to contact or friction. In daily life, static electricity will be generated due to climate, environment, and physical influences. The existence of static electricity will affect the signal or stability of electronic devices, and even cause the instrument Failure, more serious will cause serious hazards such as burning or explosion. Antistatic coatings are functional coatings with the ability to conduct electricity and eliminate accumula...
