Abstract

The invention discloses a preparation method for a marine anticorrosive paint. The preparation method comprises the following steps: adding polyvinyl chloride, xylene formaldehyde resin, zinc citrate and epoxy resin into a solvent and carrying out stirring; then adding chloroprene rubber, phosphatidylcholine, sodium sulfoxylate formaldehyde and chlorinated paraffin into the obtained mixture and carrying out stirring; and finally adding rutile titanium dioxide, a dispersant, precipitated barium sulphate, butyl acetate, polymethyl methacrylate and a stirring into the mixture obtained in the previous step and carrying out stirring and grinding so as to obtain the marine anticorrosive paint. The marine anticorrosive paint provided by the invention has excellent resistance to sea water corrosion and can resist salt fog for more than 2000 h, a 10% NaOH solution for more than 30 d and artificial seawater for more than 4200 h.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, and in particular relates to a preparation method of marine anti-corrosion coatings. Background technique [0002] my country is a large oceanic country, with a coastline of 18,000 kilometers, more than 6,500 coastal islands, and a sea area of ​​more than 3 million square kilometers under its jurisdiction. By the end of 2004, there were 1,430 ports in mainland my country. In 2004, the cargo throughput of the national ports was 4.172 billion tons, among which the coastal ports completed 2.538 billion tons. It is estimated that the throughput of the coastal ports will exceed 5 billion tons in 2010. my country's shipbuilding industry was about 8.4 million tons in 2004, and will exceed 10 million tons in 2005. As early as 2000, my country had already accounted for 90% of the world's share in container production, with a production capacity of more than 2 million boxes / a. my country ha...
