Abstract
The invention relates to the technical field of paint preparation, and in particular relates to a preparation method of low surface energy type hydrophobic marine antifouling paint. Nano-titanium dioxide and nano-silica are jointly modified by a silane coupling agent, the agglomeration of the nano-titanium dioxide is reduced, the dispersion and the stability in the acrylic resin are facilitated, and by the addition of the modified nano-titanium dioxide, the hydrophobicity of the acrylic resin is improved, so that the fouling organisms are not easily adhered to the surface of the acrylic resin,or not tightly adhered to the surface of the acrylic resin, and the surface energy of the marine antifouling paint can be reduced. Si-O bonds are introduced into the resin, an added micron-sized pigment filler and the nano silica are mixed to facilitate improvement of the hydrophobicity of the resin, and chitosan, rosin, and cuprous oxide are continuously added to promote the adhesion of the resin to the modified nano-substances or other filler, thereby further reducing the surface energy of the marine antifouling paint. The low surface energy type hydrophobic marine antifouling paint has a wide range of application.
