Abstract

The invention discloses a waterborne epoxy resin coating for ships. The waterborne epoxy resin coating comprises a component A and a component B, wherein the weight ratio of the component A to the component B is (95-110) to (0.5-1.8). The component A comprises the raw materials in parts by weight: 20-30 parts of epoxy resin E-44, 15-25 parts of siloxane modified epoxy resin, 5-15 parts of novolac epoxy resin, 1-5 parts of allyl glycidyl ether, 5-10 parts of aluminum silicate, 3-8 parts of polypyrrole hollow balls, 3-6 parts of a quartz powder, 2-6 parts of titanium dioxide microspheres, 2-6 parts of kaolin, 2-5 parts of lithium-based bentonite, 0.5-1.5 parts of zinc oxide, 2-5 parts of barium metaborate, 1-2 parts of micaceous iron oxide, 5-15 parts of poly(vinyl alcohol), 1-2 parts of polytetrafluoroethylene, 1-2 parts of emulsified silicone oil, 1-2 parts of a wetting agent, 1-2 parts of castor oil, and 15-30 parts of deionized water. The component B comprises the raw materials in parts by weight: 20-40 parts of cyclohexane tricarboxylic acid anhydride, 5-15 parts of m-xylylenediamine, 2-8 parts of propylene glycol methyl ether acetate, 2-8 parts of texanol ester alcohol, and 15-25 parts of deionized water.

Description

technical field [0001] The invention relates to the technical field of ship coatings, in particular to a water-based epoxy resin coating for ships. Background technique [0002] With the continuous development of the shipbuilding industry, the bottom of the ship and the interior of the ship are submerged in seawater all the year round, so that the original anti-corrosion layer of the structure is damaged and rusted, and these structures are difficult to move to land for maintenance. In order to prolong the service life of these ships and ensure safe production, it is necessary to apply anti-corrosion coatings on the surface of the ships to prevent corrosion in various water environments. The mechanical properties, corrosion resistance and adhesion of current ship coatings are not up to the standard. need. Contents of the invention [0003] The invention provides a water-based epoxy resin coating for ships, which has good mechanical properties, excellent corrosion resistan...
