Problems solved by technology

Traditional paints are mostly solvent-based, which contain a large amount of organic solvents, and often need to be diluted with organic solvents when used. These solvents evaporate into the atmosphere during construction and paint film drying, which is harmful to human health and pollutes the environment. fire hazard
With the increasingly stringent environmental protection regulations around the world, it is the general trend to develop environmentally friendly coatings to replace solvent-based coatings. At present, water-based epoxy coatings have technical problems of insufficient adhesion, which need to be solved urgently

Abstract

A method for preparing waterborne epoxy coating used for an inner compartment of a ship is disclosed. The method includes fully mixing aluminum nitrate, zinc borate, polyvinyl alcohol 6000 and water;adding ammonia water dropwise under stirring until the pH value of the system is 8-8.4; stirring the mixture to obtain a white emulsion suspension; performing a hydrothermal reaction, centrifugation,washing, drying, calcination and cooling to obtain a material a; stirring bisphenol A type epoxy resin, bisphenol F type epoxy resin, epoxy alkyd resin, and trimethylhexamethylenediamine to obtain a material b; and stirring the material b, the material a, nanometer talc powder, vermiculite powder, diatomite, fly ash, zinc oxide, zinc phosphate, polyethylene glycol, a film forming auxiliary agent,an antibacterial agent, a dispersing agent, an anti-mold agent, a defoamer, a wetting agent and water to obtain the coating.

Description

technical field [0001] The invention relates to the technical field of ship coatings, in particular to a method for preparing a water-based epoxy coating for ship inner tanks. Background technique [0002] Inner cabin paint is widely used in shipbuilding for the decoration and protection of inner cabin steel plates and soft cladding surfaces. Traditional paints are mostly solvent-based, which contain a large amount of organic solvents, and often need to be diluted with organic solvents when used. These solvents evaporate into the atmosphere during construction and paint film drying, which is harmful to human health and pollutes the environment. Fire hazard. With the increasingly stringent environmental protection regulations around the world, it is the general trend to develop environmentally friendly coatings to replace solvent-based coatings. At present, there are technical problems of insufficient adhesion of water-based epoxy coatings, which need to be solved urgently. ...
