Abstract

Relating to the coating field, the invention specifically relates to a special high-performance nanocomposite epoxy coating for ship and its preparation method. The special high-performance nanocomposite epoxy coating for ships comprises the following two components that: by weight parts, component one consists of epoxy resin, petroleum resin, a rust resisting pigment, a coloring pigment, an extender pigment, an additive, and a solvent, and component two consists of a solvent and a curing agent, with the component one and the component two in a weight ratio of 100:5-100:100. The preparation method includes: adding the component one into the component two, stirring them uniformly, and applying the mixture on a substrate, conducting curing at a temperature of 10DEGC-120DEG C for 5min-15d, thus forming a special high-performance nanocomposite epoxy coating for ships. The high-performance ballast tank nanocomposite epoxy coating of the invention has good corrosion resistance and impermeability, and can satisfy the requirements of new national standards for ship ballast tank paint.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-performance nano-composite epoxy coating for ships and a preparation method thereof. Background technique [0002] Ship ballast tanks have long been used to store or drain seawater to maintain the balance of the ship. In this way, the ballast tank is subjected to the infiltration of seawater and the test of alternating dry and wet all year round, so the ballast tank is the most severely corroded part of the hull and has become the biggest safety hazard of the ship. [0003] In November 2004, the Baltic and International Maritime Council (BINCO), the International Association of Classification Societies (IA Cs) and other shipping organizations established a joint working group in accordance with the requirements of MSC77 and DE47, and issued guidelines in resolution A.798(19) Based on the TSCF 15 standard of The Tanker Structure Co-operative Forum (TSCF for short), the Performance ...
