Abstract

The invention discloses a fiber oxyfluoridized-graphene composite polyimide powder paint which is prepared from the following raw materials in parts by weight: 2-4 parts of sodium myristate soap, 0.3-1 part of triethanolamine, 100-110 parts of polyimide, 10-14 parts of fluoridized graphite, 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-dimethylaminopyridine, 0.7-2 parts of hydroxyethyl cellulose, 3-4 parts of phosphorylated cotton, 0.5-1 part of calcium naphthenate, 0.8-1 part of saturated octadecacarbamide, 0.6-1 part of 1,2-dimethyl imidazole, 6-8 parts of dibutyl benzene dicarboxylate, 3-4 parts of titanium white, and right amounts of dimethylformamide, anhydrous ethanol and sulfuric acid. The hydroxyethyl cellulose and the like are added to improve the dispersity of the filler in the polymer and enhance the toughness of the finished product.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a fiber 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 prominent. Like graphene oxide, fluorinated graphene also seriously destroys the original highly conjugated structure due to the introduction of sp3 C-C struct...
