| With the progress of human society and the continuous development and updating of marine coating technology, tin-free self-polishing antifouling coating technology has gradually become the mainstream technology of biofouling protection after many product updates and iterations. However, in some cases such as small and medium-sized fishing boats, the application method is mostly roller coating. The single-coating film is thin. The ship owners mostly use the tidal range time for application, and the application time is tight, so it is difficult to meet the requirements of conducting roller coating twice. Even if it can be roller coated twice, the film thickness is difficult to meet the requirements. Self-polishing antifouling coatings have high requirements for film thickness, and the required film thickness must be reached to ensure the antifouling performance. In addition, the cost of self-polishing antifouling coating is high, so it is not suitable for small and medium-sized fishing boats. At this time, the ablative type antifouling coating shows its advantages. In response to market demand, the work aims to develop an ablative type antifouling coating, which can meet the needs of small and medium-sized ships. An acrylic matrix resin with ablative property was synthesized and used to prepare the ablative marine antifouling coating. The acrylate matrix resin with ablative properties was synthesized by radical polymerization. The hydrogen ion electrolyzed from the carboxylic acid group of the side group of the matrix resin slowly dissolved with the hydroxide ion in seawater. The bactericide in the antifouling coating slowly dissolved into the seawater to prevent marine organisms from adhering. In order to ensure the ablative performance of the matrix resin, the hydrogen ions electrolyzed from the carboxylic acid group of the matrix resin must reach certain content. The amount of acrylic acid or methacrylic acid used must be within the appropriate range. The antifouling coatings were prepared with this resin and organic antifouling agent Zineb, ZnPT, A6, and other materials such as fillers, additives, etc. The coating was characterized by means of real sea test, resistance to fresh water immersion and, microscopic appearance test. Experimental results indicated that the resin would meet the requirements under the following conditions of 4.0% initiator, 110 ℃ reaction temperature and average molecular weight of the resin of 25 000. The content of other soft and hard polymerized monomers was fixed. Experimental results indicated that when the content of carboxylic acid monomer was 25%-30%, the matrix resin had better ablative performance. The antifouling coating had excellent antifouling property after 24 months on real sea test. The antifouling coating did not blister or fall off after 12 months of immersion in fresh water. The characterization of the micro appearance of the antifouling coating surface showed that the ablative performance of the matrix resin and the surface roughness of the coating increased and holes were left on the surface after the antifouling agent was dissolved. The marine antifouling coating with ablative property has excellent antifouling properties, can protect marine organisms from fouling the boat bottom and other marine installations. It can be applied to small and medium-sized fishing boats for short-term marine pollution protection. |
