Problems solved by technology

However, when the aircraft flies at subsonic speeds less than a certain critical Mach number in icing weather conditions, the windward surface of the propeller blades will be scratched and damaged due to the impact of water droplets in the atmosphere
[0003] At present, the method of coating high-performance hydrophobic coatings on aircraft propeller blades is widely used in the world to play a protective role. However, the performance of the current hydrophobic coatings cannot fully meet the safety requirements of high adhesion strength on the surface of propeller blades.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to an acrylic paint for aircraft propeller blades. Background technique [0002] In today's world, airplanes have gradually become a means of transportation that people pay more and more attention to because of their fast and safe features. However, when the aircraft flies at a subsonic speed less than a certain critical Mach number under icing weather conditions, the windward surface of the propeller blade will be scratched and damaged due to the impact of water droplets in the atmosphere. [0003] At present, the method of coating high-performance hydrophobic coatings on aircraft propeller blades is widely used in the world to play a protective role. However, the performance of the current hydrophobic coatings cannot fully meet the safety requirements of high adhesion strength on the surface of propeller blades. Contents of the invention [0004] Based on the technical problems ...
