Problems solved by technology

[0005] At present, the slow release of antifouling agents in coatings or coatings is an effective means of preventing marine damage. In the past few decades, antifouling coatings containing toxic antifouling agents such as organotins have been widely used. Although this kind of antifouling coating has a good antifouling effect, toxic antifouling agents such as organotin are stable in water and will accumulate, which can endanger the marine ecological environment and even human health through bioaccumulation.

[0049] In the following three examples, the prepared polymer composite coating is a polyethylene / garlic powder composite coating, wherein the mass fraction of garlic powder is respectively 10%, 30%, and 50%, which are successively recorded as PE-10%Garlic, PE-30% Garlic and PE-50% Garlic. The thickness of the coating is 80 μm, the substrate is a Q235 steel sheet with a thickness of about 2 mm, and the coating is well combined with the substrate material.

[0050] The concrete preparation method of this polyethylene / garlic powder composite coating is as follows:

[0051] 1. Weigh 100g of polyethylene (PE) powder, ultrasonically, and dry; add garlic powder (about 20 μm in size) to the polyethylene powder in proportion, and mechanically stir until uniform, and finally obtain a mixed powder of polyethylene / garlic powder;

[0052] 2. Clean the substrate with acetone, ethanol, and deionized water in sequence, and use 60 mesh brown corundum sand to roughen the surface of the Q235 st...

Description

technical field [0001] The invention relates to the technical field of composite coatings, in particular to a polymer composite coating and its preparation method and application. Background technique [0002] In recent years, with the rapid development of marine transportation, seabed oil and minerals, mariculture, seawater desalination, marine power generation and other industries, marine biofouling and corrosion have attracted more and more attention. When a material or object is immersed in seawater, the surface is quickly covered by a single layer of polymer material to form a regulating film. Immediately afterwards, bacteria and single-cell diatoms will quickly adhere to the regulatory membrane, and the bacteria will secrete exopolysaccharides, which will connect the bacteria and the substrate, and the bacteria and the substrate to form a thin layer of mucous membrane. The shells below the waterline of ships and docks have been in contact with seawater for a long time...
