Abstract

The invention provides a water-resistant and antibacterial marine coating and a preparation method thereof, wherein the marine coating comprises: 15-30% ethyl methacrylate, 12-15% butyl acrylate, 10-10% triethylamine 14%, polymer rubber powder 6‑18%, styrene-acrylic emulsion 11‑14%, zinc oxide 2.5‑3.5%, triallyl cyanurate 6.5‑8.5%, dimethyldithioglycolate isooctyltin 20‑25%, glycol ether 2‑10%, diene epoxy resin 7‑8%, polyvinylpyrrolidone 1.5‑2.5%, nano silver particles 5.8‑6.5%, polyacrylamide 3.5‑5.8% and additives 12‑24%. The water-resistant and antibacterial marine coating of the present invention improves the water resistance and antibacterial properties of the coating formed after the coating is applied by optimizing the components and the content of the components in the coating, so that the surface layer of the ship using the coating of the present invention is not easy to wear and destruction, with a longer service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-resistant and antibacterial marine coating and a preparation method thereof. Background technique [0002] Marine coatings are a general term for coatings used in various parts of ships and marine engineering structures, which can meet the requirements of preventing seawater, marine atmospheric corrosion, marine organisms adhesion and other special requirements. By coating the surface and parts of the ship with paint, the hull and its parts can be protected and their service life extended. However, although the existing marine coatings can avoid the erosion of seawater and the atmosphere, the coatings formed after coating have poor water resistance and antibacterial properties. After long-term use, it is easy to cause wear and damage to the hull surface coating. [0003] Therefore, in view of the above problems, it is necessary to propose a further solution. Contents ...
