Anti-corrosion and anti-abrasion coating for power generator blade and preparation method thereof

Abstract

The invention discloses an anti-corrosion and anti-abrasion coating for a power generator blade and a preparation method thereof. The anti-corrosion and anti-abrasion coating is prepared from the following components in parts by weight: 30 to 40 parts of epoxy resin, 12 to 20 parts of organic silicon resin, 5 to 10 parts of graphite powder, 3 to 7 parts of mica powder, 4 to 8 parts of hydroxy propyl methyl cellulose, 5 to 12 parts of nanometer silicon dioxide, 7 to 16 parts of anti-abrasion filler, 1 to 5 parts of preservative, 1 to 3 parts of curing agent, 0.4 to 1.4 parts of flattening agent, 0.2 to 0.6 part of dispersant, and 20 to 30 parts of solvent. The anti-corrosion and anti-abrasion coating has the advantages that the anti-corrosion and high temperature-resistant properties are realized; the anti-abrasion property is good, the adhering strength is excellent, the dielectric property is good, the size stability of the product is good, the hardness is high, the flexibility is better, and the stability to alkaline and most of solvents is realized; the anti-corrosion, air-blocking and water-blocking properties are good, the service life is long, and the problems of foaming, cracking, whitening, delaminating and the like are solved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-corrosion and wear-resistant coating for generator blades and a preparation method thereof. Background technique [0002] Coating refers to a type of liquid or solid material that can form a film on the surface of an object under certain conditions for protection, decoration or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). Because most of the early paints used vegetable oil as the main raw material, they were also called paints. Now synthetic resins have replaced vegetable oils, so they are called paints. Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and...

AI Technical Summary

Problems solved by technology

[0003] In my country, the research on the coating of generator blades is relatively late, and the design idea is hydroxyacrylic resin + isocyanate curing agent, and the low-temperature performance of the coating formed by it is poor; there is also the composition of hydroxyacrylic resin + polyester resin + isocyanate curing agent. However, the weather resistance and abrasion resistance of the coating film are poor, and the dispersion uniformity of the raw materials in the coating is poor, and the bonding force between the coating and the generator blade is weak, which cannot meet the higher requirements for the performance of the generator blade coating in my country.
