Problems solved by technology

However, the direct use of scaly zinc powder in water-based zinc-rich anti-corrosion coatings has problems such as poor anti-sedimentation, difficult wetting and dispersion, and easy agglomeration, which leads to uneven gloss and uneven surface of zinc-based coatings, which affects the coating. Mechanical properties, to some extent limit the application of coatings
Therefore, it is an urgent problem to be solved at this stage to study the formulation of zinc-rich anti-corrosion coatings that can overcome the problems of easy sedimentation and poor dispersion of zinc powder.

Embodiment Construction

[0017] The water-based zinc-rich polyacrylate anticorrosion coating modified by organic montmorillonite is prepared by the following steps:

[0018] (1) Add montmorillonite and cetyltrimethylammonium bromide to deionized water, ultrasonically oscillate to make them fully dispersed, transfer to a constant temperature water bath at 80°C, stir magnetically at constant temperature for 8 hours, filter, wash with water, drying, grinding and sieving to obtain organically modified montmorillonite;

[0019] (2) Mix acrylic acid, methyl methacrylate, butyl acrylate, isooctyl acrylate, dibenzoyl peroxide, and azobisisobutylcyanide in a mass ratio of 1:3:2.5:1.5:0.01:0.008 Stir evenly to obtain a monomer / initiator mixture;

[0020] (3) Add propylene glycol methyl ether acetate into the reaction kettle equipped with a condenser and agitator, raise the temperature to 110°C, and start adding 3 / 5 of the monomer / initiator mixture dropwise at a constant speed, and control it within 3h to compl...

Abstract

The invention discloses water-based zinc-rich polyacrylate anticorrosive paint modified by organic montmorillonite. A production method for the water-based zinc-rich polyacrylate anticorrosive paint modified by organic montmorillonite is characterized by comprising the following steps: firstly, preparing organic modified montmorillonite; then, preparing hydroxyl-containing polyacrylate aqueous dispersion through step-by-step polymerization; and finally, taking the hydroxyl-containing polyacrylate aqueous dispersion as a film-forming agent, taking zinc phosphomolybdate as anticorrosive packing,taking the organic modified montmorillonite as an anti-sinking agent, supplementing by other auxiliaries, mixing, grinding and dispersing, thereby obtaining the water-based zinc-rich polyacrylate anticorrosive paint modified by organic montmorillonite. The anticorrosive paint provided by the invention is good in dispersion, and a film-formed coating is flat in surface, is compact, and is excellent in mechanical property and corrosion resistance.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to a production method of an organic montmorillonite-modified water-based zinc-rich polyacrylate anti-corrosion coating. Background technique [0002] Metal corrosion is a very serious and most common problem that people face, and the metal scrapped due to corrosion reaches more than 100 million tons every year in the world. Waterborne zinc-rich anti-corrosion coatings are widely used because of their unique protection mechanism, zero VOC, excellent anti-corrosion performance and reasonable price. Compared with spherical zinc powder, flake zinc powder has more advantages in hiding ability, floating ability and shielding ability. Using flake zinc powder to prepare coatings can greatly reduce the amount of zinc powder. However, the direct use of scaly zinc powder in water-based zinc-rich anti-corrosion coatings has problems such as poor anti-sedimentation, difficult wetting and dispersion...
