Abstract

The invention relates to anticorrosive coating for a water ballast tank and a preparing method thereof. The preparing method includes: adding bisphenol A epoxy resin, novolac epoxy resin, bisphenol F epoxy resin and petroleum resin into a mixed solvent of xylene and n-butyl alcohol; adding wet-process sericite powder, silica powder, barite powder, titanium dioxide, fumed silica, bentonite, an active epoxy toughening diluting agent, a silane coupling agent, a polyacrylate co-polymer and polyether-modified polymethyl alkylsiloxane; mixing; stirring; grinding to obtain an A component of the high-solid anticorrosive coating of the water ballast tank; mixing modified phenolic amine and modified amine to obtain a B component; and mixing the A component and the B component when the coating is to be used. The coating has characteristics of good mechanical performance, flexibility, sea water resistance and chemical resistance, and can be used as the coating for the water ballast tank. The preparing method is simple, low in cost and low in VOC content and meets requirements on environment protection.

Description

technical field [0001] The invention relates to an anti-corrosion coating for ballast water tanks and a manufacturing method thereof, which can be used for anti-corrosion of ballast water tanks of ships, and can also be used for anti-corrosion of steel materials such as ocean platforms, steel structures and ships. Background technique [0002] The ballast water tank of the ship is always under the condition of alternating dry and wet conditions of empty tank / sea water ballast, and its corrosion environment is very harsh. The coating used is very prone to corrosion damage, which brings safety hazards to the ship. Therefore, in 2008, the International Maritime Organization implemented the mandatory standard "Protective Coating Performance Standards for Special Seawater Ballast Tanks of All Types of Ships and Double-Side Skin Spaces of Bulk Carriers", which not only greatly improved the performance standards of coatings, but also added condensation tests and cathodic protection ...
