Embodiment 1

[0016] Nano multifunctional water-based anti-corrosion paint, its components are proportioned by mass percentage: 10% water, 10% montmorillonite slurry, 25% epoxy modified polyvinyl alcohol solution, 0.2% dispersant, 4% film former, 0.2% defoamer, 0.2% fungicide, 40% acrylic emulsion, 0.6% thickener.

[0017] Preparation method: first modify polyvinyl alcohol with epoxy resin for water resistance, then mix and disperse it with montmorillonite slurry in a certain proportion to prepare nano-sized low-cost modified polyvinyl alcohol film-forming slurry, and then Cross-linking with acrylic emulsion to prepare a high-performance anti-corrosion paint, and then adding a silicone water-based cross-linking agent during use to completely change the water resistance of the anti-corrosion paint to obtain a finished paint.

Abstract

The invention discloses a nanometer multifunctional aqueous anticorrosive paint, which comprises, by mass, 10% of water, 10% of montmorillonite slurry, 25% of an epoxy modified polyvinyl alcohol liquid, 0.2% of a dispersing agent, 4% of a film-forming agent, 0.2% of a defoaming agent, 0.2% of a bactericide, 40% of acrylic emulsion and 0.6% of a thickening agent. The preparation method comprises: mixing a modified polyvinyl alcohol liquid and montmorillonite slurry according to a certain ratio, and dispersing at a high speed to prepare nano-scale polyvinyl alcohol film-forming slurry with a certain film-forming property; and carrying out a polymerization reaction with acrylic emulsion to prepare the high-performance aqueous anticorrosive paint. According to the invention, the film-forming slurry has a certain film-forming function and thixotropic property so as to substantially reduce the adding amounts of the film-forming agent and the emulsion to greatly reduce the cost, montmorillonite has high expansion performance when meeting water, and industrial dust can be even added during the paint preparation process so as to turn waste into treasure and protect the environment, such that the problems of high production cost and poor performance of the existing multifunctional aqueous anticorrosive paint are solved.

Description

technical field [0001] The invention relates to the technical field of anticorrosion paints, in particular to nanometer multifunctional water-based anticorrosion paints. Background technique [0002] Anti-corrosion paint is a type of paint that can be used on the surface of an object to protect the interior of the object from corrosion. It is a type of paint more commonly used than anti-corrosion paint in industrial construction. It is widely used in aviation, shipbuilding, chemical industry, oil pipelines, steel structures, bridges, oil drilling platforms and other fields, and is favored by construction manufacturers. [0003] There are many kinds of anti-corrosion paint, which can be generally divided into: epoxy anti-corrosion paint, polyurethane anti-corrosion paint, acrylic anti-corrosion paint, inorganic anti-corrosion paint, perchlorethylene anti-corrosion paint, chlorinated rubber anti-corrosion paint, high chlorinated polyethylene anti-corrosion paint; Uses can be ...
