Abstract

The invention discloses an anti-bacteria oxygen graphite fluoride-composite polymide powdery coating, which is prepared from the following raw materials in parts by weight: 3-4 parts of butyl benzyl phthalate, 100-110 parts of polyimide, 10-14 parts of graphite fluoride, 0.1-0.3 part of potassium persulfate, 1-2 parts of sodium nitrate, 0.1-0.4 part of potassium permanganate, 4-6 parts of sebacic acid, 0.5-1 part of phosphorus pentoxide, 0.1-0.2 part of dicyclohexylcarbodiimide, 0.1-0.2 part of 4-dimethyl aminopyridine, 1-2 parts of octyl isothiazolinone, 2-3 parts of calcium propionate, 0.4-1 parts of sodium alkyl benzene sulfonate, 0.6-1 parts of 2-bromo-4-methyl-phenol, 4-7 parts of tetrabutyl titanate, 0.8-1 parts of calcium sulfonate, 2-3 parts of polyvinyl alcohol, 0.4-1 parts of stearic acid, a proper amount of dimethyl formamide, a proper amount of sulfuric acid and a proper amount of absolute ethanol. By adding calcium propionate and the like, the anti-bacteria anti-corrosion performances of the finished product material can be effectively enhanced, and the storage stability of the finished product can be improved.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a bacteriostatic oxyfluorinated graphene composite polyimide powder coating and a preparation method thereof. Background technique [0002] Fluorinated graphene maintains the two-dimensional carbon layer structure of graphene, and its chemical composition is similar to polytetrafluoroethylene, so it has the properties of both graphene and polytetrafluoroethylene. Fluorinated graphene has high temperature resistance equivalent to that of polytetrafluoroethylene. It begins to decompose slowly when the temperature is higher than 260 ° C, and decomposes rapidly when the temperature rises above 400 ° C. The properties of fluorinated graphene such as hydrophobicity, solvent resistance and chemical inertness are also particularly outstanding. Like graphene oxide, fluorinated graphene also seriously destroys the original highly conjugated structure due to the introduction of sp3...
