Preparation method for single-component antistatic moisture-curable polyurea aluminum powder anticorrosive paint

Abstract

The invention relates to a preparation method for a single-component antistatic moisture-curable polyurea aluminum powder anticorrosive paint. The method comprises the following steps: (1) carrying out stirring and blending, i.e., blending and dissolving 0.02% by weight of a dispersant, adding 12% of aluminum powder, carrying out stirring at a linear speed of 16 m / s for 15 min and adding 3.98% of an aluminum powder locating agent into the aluminum powder so as to form an aluminum slurry solution; (2) filtering 24% by weight of low molecular polyethylene wax with 200-mesh filter cloth into the aluminum slurry solution and carrying out stirring at a linear speed of 16 m / s for 30 min; and (3) filtering 60% of polyurea resin with the 200-mesh filter cloth into a paint adjusting kettle and carrying out stirring for 30 min. The invention has the following beneficial effects: the isocyanate polyurea resin is used as a main body structure, non-floating aluminum slurry is cooperatively used for shielding and conduction, so functions of a plurality of single-function anticorrosive paints are integrated together, and the paint provided by the invention provides shielding and antirust functions, is simple to operate and has a good anticorrosive effect.

Description

technical field [0001] The invention relates to a paint preparation technology, in particular to a preparation method of a single-component antistatic moisture-cured polyurea aluminum powder anticorrosion paint. Background technique [0002] Anti-corrosion paint is a type of paint used on the surface of objects to protect the interior of objects from corrosion. It is widely used in aviation, ships, chemicals, oil pipelines, steel structures, bridges, oil brick well platforms and other fields. 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 and inorganic anti-corrosion paint according to the composition; according to the application, it can be divided into anti-corrosion paint for pipelines, anti-corrosion paint for ships, anti-corrosion paint for metal, and furniture. Anti-corrosion paint, anti-corrosion paint for automobiles, anti-corrosion paint for...
