Problems solved by technology

[0002] The rudder blade is an important part of the ship, which is submerged in seawater all the year round. In order to prevent seawater corrosion, most of the rudder blades are coated with anti-rust paint on the surface, but the effect is not very satisfactory. Rudder blades are often corroded. On the other hand, After the rudder blade is corroded, it is continuously impacted by seawater, which leads to changes in the geometric parameters of the rudder blade, which has a certain impact on the working efficiency of the rudder blade. If it needs to be replaced, not only the docking cost and repair cost are high, but also the cost Relatively expensive, the total cost required is huge
At present, rudder blades with low cost and resistance to seawater corrosion and impact are still rare

Embodiment Construction

[0010] figure 1 Among them, the rudder blade 1 is made of steel material. After derusting and roughening, a number of uneven micro-pits are formed on the outer surface of the rudder blade 1 (the micro-pits are not shown in the figure). After coating epoxy resin 2, Epoxy resin 2 penetrates into several micro pits, and forms an epoxy resin protective layer that is not easy to peel off after curing. Due to the good chemical stability and impact resistance of epoxy resin, the epoxy resin protective coating can effectively resist the impact of seawater and rust, so that the rudder blade 1 can work stably and efficiently for a long time.

[0011] figure 2 Among them, the rudder blade 1 is made of steel material. After derusting and roughening, a number of uneven micro pits are formed on the outer surface of the rudder blade 1. An interlining 3 is set between the rudder blade 1 and the epoxy resin 2. The epoxy resin 2 Penetrate into several micro pits, and form an epoxy resin prot...
