A kind of long-lasting water-based ship interior tank paint and preparation method thereof

Abstract

The invention discloses long-acting waterborne ship interior paint and a preparing method thereof. The long-acting waterborne ship interior paint comprises 40-60 parts of waterborne alkyd resin, 1-2 parts of mesoporous silica hollow spheres, 10-20 parts of an amino silane coupling agent, 0.5-0.7 part of a wetting dispersant, 15-23 parts of pigments and filler, 0.1-0.5 part of a cerium nitrate corrosion inhibitor (5% water solution), 0.1-0.3 part of an ultraviolet absorber, 0.2-0.5 part of a pH regulator, 0.1-0.3 part of an adhesion promoter, 1-2 parts of a drier, 0.3-0.7 part of a thickening agent, 0.2-0.6 part of a defoaming agent and 10-15 parts of water. The VOC of the paint is only 8 g / L, the artificial ageing resistance reaches 300 h, the salt fog resistance of a matched coating reaches 1000 h, and the water resistance reaches 21 d; through low-spreading flame resistance and smoke and toxic tests, the long-acting protection requirement of accommodation and building steel structures of ships and marine platforms is met.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a long-acting water-based ship interior paint and a preparation method thereof. Background technique [0002] In the process of shipbuilding, a large amount of interior paint is used to decorate and protect the surface of the steel plate in the interior. Due to the small space in the interior of the hull, inconvenient painting operations, and poor ventilation, there are hidden dangers of fire, poisoning and other safety accidents during the construction process. At present, the most widely used interior paint in the shipbuilding industry is solvent-based alkyd paint. The solvent-based alkyd paint contains about 50% organic solvents, which is easy to cause fire hazards during construction, pollute the interior cabin environment, and pose a threat to the health of the cabin staff. [0003] The new water-based alkyd marine interior paint uses water as the dispersion medium, which...

Problems solved by technology

[0005] Although the implementation of the above two processes has improved the anti-corrosion performance of the water-based alkyd to a certain extent, it still does not meet the anti-corrosion requirements of the ship's interior in the marine atmospheric environment.
