Embodiment 1

[0035] The weight distribution ratio of each component crude drug of the superhydrophobic paint anticorrosion of power system fittings of the present invention is as follows:

[0036]

[0037] Take one group of components of the embodiment in the table below as an example to describe the preparation method of the present invention in detail:

[0038] A preparation method of an anti-corrosion superhydrophobic coating for metal fittings in a power system, the method comprising the following processes:

[0039] a. Preparation of superhydrophobic anticorrosion sol

[0040] Add the amino-modified nano-fluoride silica and dispersant to the dispersant, form a stable and uniform sol after mixing, then add carbon black, mica powder, titanium dioxide, defoamer, wetting agent and zinc powder in sequence and stir evenly ;

[0041] b. Add dispersant and polyurethane to the superhydrophobic anticorrosion sol obtained in step a, stir for 30min, and keep the rotating speed at 300rpm;

Embodiment 7

[0061] According to the method of the present invention, the nanometer fluorinated silicon dioxide after the preparation amino modification accounts for the coating of 5% of total mass, its coating is sprayed in the epoxy coating, the coating is carried out dispersion electron microscope scanning and coating surface water Contact angle test. Simultaneously, the product obtained in Example 1 of the present invention is carried out to the same test,

[0062] Superhydrophobic coating for anti-corrosion of metalware containing 5% amino-modified nano-fluorinated silica Coating of Example 1 dispersive scanning electron microscopy Such as image 3 As shown, the particles on the surface of the coating are sparsely arranged, so water droplets are more likely to enter the gaps between the particles. Such as Figure 4 As shown, the surface particles are closely arranged, so water droplets are not easy to enter the gaps between the particles Coating Surface W...

Abstract

The invention relates to an organic nano anticorrosion paint and its preparation method, and especially provides an antiseptic super-hydrophobic paint for an electric power system fittings and its preparation method, the antiseptic super-hydrophobic paint comprises the following components by weight: 11-20 parts of amino-modified nano fluorine silica, 40-50 parts of dispersant, 0.6-3 parts of carbon black. 3-6 parts of mica powder, 5-10 parts of titanium dioxide, 0.3-0.6 parts of antifoaming agent, 0.2-0.5 parts of wetting agent, 0.5-2 parts of zinc powder, 25-40 parts of membrane-forming substrate and 2-4 parts of curing agent; wherein the amino-modified nano fluorine silica accounts for 10-20% of total mass; the amino-modified nano fluorine silica takes nano silica, KH550, a fluorosilicone coupling agent, water and a solvent as raw materials, and the materials are charged according to the proportion of 5-10: 0.2-0.3: 0.5-0.8: 0.05-0.1: 20-25, the materials are performed with a stirring reaction for 5 hours at 75-85 DEG C, and filtered and dried to obtain the product. The solvent is acetone, ethanol or benzene. The preparation method has the advantages of no expensive equipment, simple process, low production cost and good hydrophobic anticorrosion effect.

Description

technical field [0001] The invention relates to an organic nano anti-corrosion coating and a preparation method thereof, in particular to an anti-corrosion coating and a preparation method thereof which is applied to the surface of metal fittings in a power system and uses nano-scale silicon dioxide particles as an effective component. Background technique [0002] Metal corrosion brings huge losses to the national economy every year. The use of nanoparticles as coating additives has become a hotspot in the research of anti-corrosion coatings. How to stably and uniformly disperse nanoparticles into the base material is the key to the application of nanoparticles in coatings. If nano-TiO2 or nano-ZnO concentrate is added to acrylic paint, it can not only improve the mechanical properties of the coating, but also shield 99% of ultraviolet rays. Ti nano-polymer is made by high temperature and high pressure grinding, which is added into resin as a filler to make anti-corrosion...
