Example Embodiment

[0029] Example 1

[0030] A preparation method of graphene modified anticorrosive coating includes the following steps:

[0031] (1) Preparation of graphene-resin composite slurry

[0032] Add the resin to the solvent in proportion to dissolve. After uniformly dissolving, add stabilizer and graphene powder to the resin in proportion. The graphene powder should be pre-dispersed before adding. The specific treatment process is: another of the same category as the above Solvent and place the graphene powder in the solvent. The mass ratio of the graphene powder to the solvent is 1:250-300, and then ultrasonically disperse for 20-40 minutes. After the dispersion is completed, pass the vacuum with a filter cloth of more than 500 meshes. The solvent is removed by the suction filter to obtain wet graphene, and then the lubricating graphene is added to the resin, and then the stabilizer, graphene and resin are mixed uniformly by stirring. After the mixing is uniform, the dispersion process i...

[0040] Example 2

[0041] A preparation method of graphene modified anticorrosive coating includes the following steps:

[0042] (1) Preparation of graphene-resin composite slurry

[0043] The epoxy resin is added to the absolute ethanol in proportion, and the epoxy resin is uniformly dissolved by stirring to reduce the viscosity of the epoxy resin. The mass ratio of the epoxy resin to the absolute ethanol is 70:30, which is uniformly dissolved Then, first add polyvinylpyrrolidone to the epoxy resin in proportion and stir and mix uniformly. The mass ratio of epoxy resin to polyvinylpyrrolidone is 100:1, then add graphene powder in proportion and stir and mix uniformly. The mass ratio of the graphene powder is 98.8:1.2. After stirring and mixing uniformly, the shearing emulsification dispersion process is used for dispersion treatment for 0.5 h. After the treatment is completed, the graphene-resin composite slurry is obtained. Among them, the graphene powder should be pre-dispersed ...

[0053] A preparation method of graphene modified anticorrosive coating includes the following steps:

[0054] (1) Preparation of graphene-resin composite slurry

[0055] The alkyd resin is added to xylene in proportion, and the alkyd resin is uniformly dissolved by stirring to reduce the viscosity of the alkyd resin. The mass ratio of alkyd resin to xylene is 65:35. After uniform dissolution, First add the silane coupling agent to the alkyd resin according to the proportion and stir and mix evenly. The mass ratio of the alkyd resin to the silane coupling agent is 100:1.5. Then add the graphene powder according to the proportion and stir and mix evenly. The mass ratio of graphene powder is 98:2. After stirring and mixing uniformly, a high-speed homogeneous stirring dispersion process is used for dispersion treatment for 1.5 hours. After the treatment is completed, a graphene-resin composite slurry is obtained. Among them, the graphene powder should be pre-disperse...

Abstract

The invention discloses a preparation method for graphene modified anticorrosive paint. The preparation method comprises the following steps: (1) adding resin into a solvent to dissolve, adding a stabilizer and graphene powder into the resin after the resin is dissolved, uniformly mixing, and treating by adopting a dispersing process, thereby obtaining graphene-resin composite slurry; (2) additionally getting resin to mix with the solvent and a filler to obtain a mixture, adding a dispersing agent into the uniformly-mixed mixture, and treating by adopting a dispersing process, thereby obtaining color paste, wherein the type of the additionally-got resin is the same as that of the resin in the step (1); and (3) adding the color paste prepared in the step (2) into the graphene-resin composite slurry prepared in the step (1), and filtering after grinding and dispersing, thereby obtaining the finished paint. According to the preparation method, a path of adding a corrosive medium to protected matrix is added, so that the protection time of a coating on the matrix is prolonged, and the purpose of long-acting corrosion prevention is achieved; and the defects of poor weather resistance, low barrier property, short service life and the like of the current paint are overcome.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a preparation method of graphene-modified anti-corrosion coatings. Background technique [0002] There are many types of existing anti-corrosion coatings, incomplete statistics, there are more than 1,000 types of anti-corrosion coatings in my country, the traditional classification by resin is epoxy, epoxy asphalt, asphalt, chlorinated rubber, chlorosulfonated polyethylene, polyvinyl chloride , perchlorethylene, urushiol resin, ethyl silicate, high chlorinated polyethylene, polyurethane, polyurethane bitumen, phenolic, alkyd paint, etc. Epoxy resin anti-corrosion coatings are the most important type of heavy-duty anti-corrosion coatings.
