Embodiment 1

[0025] Put 0.6 g styrene and 2.5 g trifluorooctyl methacrylate monomer in a 100 mL three-necked flask and mix evenly, add 0.03 g azobisisobutylcyanide to the system, and the reaction temperature is 70 o C. The reaction system continued for 10 hours to synthesize styrene / tridecafluorooctyl methacrylate copolymer. Dissolve the styrene / tridecafluorooctyl methacrylate copolymer with an appropriate amount of tetrahydrofuran, precipitate with methanol, wash repeatedly, and dry the precipitate at a constant temperature (60 oC) to a constant weight to obtain a fluorine-containing acrylate binary copolymer for use. Add 1.0 g of flake graphite, 1.2 g of potassium nitrate and 46 mL of concentrated sulfuric acid into a 500 mL four-neck flask and mix evenly. Slowly add 6.0 g of potassium permanganate in an ice-water bath and stir. Then the temperature was raised to 40° C., and the reaction was stirred at high speed for 6 hours. Slowly add 80 mL of distilled water to the reaction system a...

Abstract

The invention discloses a preparation method of a super-hydrophobic graphene wind turbine blade surface protective coating material. The preparation method comprises the following steps: (1) synthesizing a fluorine-containing acrylate bipolymer; (2) preparing graphene oxide by using an improved Hummers method, and (3) completing nucleophilic substitution reaction in an alkaline environment to prepare alkynylated graphene, and (4) grafting the fluorine-containing acrylate copolymer to the surface of the graphene oxide to finish surface modification of the graphene material. According to the method, the surface contact angle of the material can reach 153.76 degrees, the problem of low adhesive force of a matrix of the material is solved on the basis of super-hydrophobic performance, and thecompatibility of the material with an organic solvent is also improved. The bipolymer can more stably show the effect of low surface energy on the surface of graphene through a chemical grafting method, and the corrosion resistance and permeation resistance properties of the graphene coating material are better enhanced in cooperation with the good mechanical properties of the graphene material.

Description

technical field [0001] The invention relates to a method for preparing a superhydrophobic graphene wind power blade surface protective coating material and its products, in particular to a modified graphene material with superhydrophobic properties, which is applied to anti-corrosion coating materials and used as coating fillers and other anti-corrosion materials. Anti-fouling materials and other fields. Background technique [0002] Social and economic development is accompanied by huge energy consumption, and the traditional energy industry faces problems such as insufficient resource supply and serious environmental pollution. Therefore, the discovery and utilization of green energy has become the first choice to break these shackles. Among them, wind energy, as a renewable green new energy, can effectively alleviate the crisis of traditional energy sources. (Xu Dongqing. Development status of wind power generation technology and analysis of industry development [J]. Ma...
