Composite deck coated with anticorrosive paint

Abstract

The invention discloses a composite deck coated with anticorrosive paint, and relates to the field of shipbuildings. A deck coating and a wear-resistant coating are respectively applied to the upper and lower layers of outer layer of a steel plate, wherein the deck coating consists of hydroxyl acrylic resin, polyether polyol, olefine resin, an antifoaming agent, a flatting agent and a pigment / filler, and the wear-resistant coating is composed of aluminum oxide ceramic powder, silica powder, carbon black, a polyacrylate copolymer solution and anhydrous dimethylbenzene. The composite deck coated with the anticorrosive paint, due to excellent adhesion, abrasive resistance, weather fastness, light aging resistance, seawater resistance and salt fog resistance of the coatings thereof, is applicable to corrosion prevention for decks of ships and ocean platforms which require weather fastness, skid and wear resistance, and seawater corrosion resistance as well as steel and iron surfaces of other ocean facilities. The preparation method of the composite deck coated with the anticorrosive paint is simple in process, free from special equipment and relatively cheap in price.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a composite deck coated with corrosion-resistant paint. Background technique [0002] At present, the existing ships and offshore platform deck steel generally use epoxy anti-corrosion paint and alkyd deck paint for the anti-corrosion of the steel surface of ships, docks and other marine facilities, which have good weather resistance and salt spray resistance , the disadvantage is that the paint film has poor abrasion resistance, and fillers such as quartz sand and rubber particles are added after the need to increase the anti-skid, the paint film is rigid, and the impact resistance is poor. There are short anti-corrosion service life, poor weather resistance, poor wear resistance, easy pulverization, poor corrosion resistance, and poor toughness. In the process of hoisting and construction, it is easy to cause damage to the coating and affect the anti-corrosion effect. Contents of ...
