Problems solved by technology

The main problem in the preparation of polyaniline conductive anti-corrosion coatings by this method is that the dispersion of polyaniline particles in the coating is not good. Because nano-polyaniline particles are easy to agglomerate, it is difficult to distribute in the state of nanoparticles in the coating, thus affecting the coating. Conductive and anti-corrosion effect

Abstract

The invention relates to an aqueous nano polyaniline-epoxy acrylic resin conductive anticorrosion primer base, which is prepared by mixing and stirring a nano polyaniline-epoxy acrylic resin mixture, aqueous acrylic acid anticorrosion emulsion, pigment-filler, and auxiliary agents. An in-situ emulsion polymerization method is adopted to make aniline carry out polymerization in epoxy acrylic resin to form resin wrapped nano polyaniline particles, which are evenly dispersed in resin, and then the particles are mixed with aqueous acrylic acid anticorrosion emulsion and pigment-filler to prepare the primer base. The anticorrosion primer base is enable to have an aqueous property, an in-situ emulsion polymerization technology and a nano technology are well combined, nano polyaniline particles are well dispersed in paint, the coating has a good conductive property and anticorrosion performance therefore, on the other hand, the oil-water layering is avoided because no solvent is added, and thus the primer base can be well stored.

Description

technical field [0001] The invention is a water-based nano polyaniline-epoxy acrylic resin conductive anti-corrosion primer coating, which belongs to the polymer conductive anti-corrosion coating in water-based coatings and nano anti-corrosion materials. Background technique [0002] Conductive anti-corrosion coating is a new type of anti-corrosion coating. This coating can not only conduct current and eliminate the accumulated static charge on the surface of the substrate, but also has good anti-corrosion performance. It is a functional special coating that can be applied to any The surface or interior of a shape substrate. Conductive anti-corrosion coating has many advantages such as convenient construction, simple equipment, low cost and wide application range. This kind of coating is mainly used in petroleum, chemical, construction, aviation and military fields. Traditional conductive anti-corrosion coatings generally add conductive materials (such as metal, graphite, e...
