| Abstract: |
| Objective To solve conglobation of nanometer TiO2 in coating and improve anti-corrosion, hydrophobicity and ultraviolet aging resistance of coating. Methods Chlorine ether resin was taken as the main film-forming material of aerospace coatings, rutile TiO2 nanoparticles modified by fluoroalkyl silane was taken as the primary light absorber and water repellent to produce a new aerospace coating in combination with other fillers and pigments. The mechanical property, electrochemistry property, hydrophobicity and ultraviolet aging resistance of coating were researched respectively through methods such as drawing, hardness testing, electrochemical polarization curve, contact angle measurement and artificial UV accelerated aging testing, etc. Results The dispersity of modified rutile TiO2 nanoparticles and its compatibility with chlorine ether resin were improved. The corrosion prevention, surface hydrophobicity and ultraviolet aging resistance of coating was the best, and mechanical properties such as adhesive force, rigidity, etc. also met basic using requirements on aerospace coating when the volume of addition was 2%-3%. Conclusion The coating solves the conglobation of nanometer TiO2 in coating and improves anti-corrosion, hydrophobicity and ultraviolet aging resistance of coating. |
