Abstract
The invention discloses a marine coating with high strength and low surface energy. The coating is prepared by mixing and dissolving chlorinated rubber and epoxy resin E44, and adding coupling-agent-coated modified nanometer alumina and other effective auxiliary agents at the same time; and all the components are uniformly dispersed and draw on each other's strength. Due to the composition of a C-Cl bond with great polarity, chemical corrosion resistance of the coating is increased, and the disadvantages of great brittleness, low toughness, poor adhesion on a substrate and the like of a chlorinated rubber coating are improved; meanwhile, added metal magnesium powder can significantly improve permeability and electrochemical corrosion resistance of the coating so as to effectively improve durability and weather resistance of ships; and boron fiber added in the coating can improve the strength of the coating. The prepared marine coating provided by the invention has the characteristics of high strength, low surface energy, difficult adhesion of marine microorganisms on a smooth coating film, high erosion resistance, etc.
Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of high strength low surface energy type ship coating and preparation method thereof.
Background technology
Compared with land natural condition, the bacterium etc. in the impact of the temperature of the ultraviolet in ocean environment, salt fog, temperature and humidity, seawater and flow velocity, dissolved oxygen of seawater and saltiness, wave, the shock of floating matter, marine organisms, ocean bottom soil all can cause the corrosion of steel beam column to some extent.Boats and ships are in the corrosive environment of this harshness for a long time; make steel beam column erosion rate very fast; address this problem and need to develop a kind of novel ship paint in the above position of planking load water line or hull bottom; form the impact that layer protective layer reduces the oceanic climate corrosion of strong variations, and this coating needs to possess following characteristic: good ornamental, resistance to sea atmosphere corrosion, resistance to tanning by the sun property, salt fog resistance, high adhesive force and good snappiness etc.
