Problems solved by technology

However, the anticorrosion paint compounded with acrylic emulsion and self-crosslinking resin in the prior art mainly focuses on salt spray resistance and oil stain resistance, and needs to add a large amount of self-crosslinking resin. This kind of anticorrosion paint not only has high cost, but also Long drying time, poor anti-sticking performance

Abstract

The invention discloses a water-based after-tack-resistant anticorrosive primer and a preparation method and application thereof.The water-based after-tack-resistant anticorrosive primer is prepared from water-based epoxy ester resin, acrylic emulsion and auxiliaries, the mass ratio of the water-based epoxy ester resin to the acrylic emulsion is 6-10: 15-25, the solid content of the acrylic emulsion is 45%-50%, and the particle diameter is 0.1-0.2 <mu>n; and the lowest film forming temperature is 20-25 DEG C. The water-based after-tack-resistant anticorrosive primer disclosed by the inventionhas excellent after-tack-resistant performance and is high in drying speed.

Description

technical field [0001] The invention belongs to the technical field of industrial anticorrosion paints, and in particular relates to a water-based anti-adhesion anticorrosion primer and a preparation method and application thereof. Background technique [0002] Acrylic emulsion has many advantages such as high solid content, fast drying speed, and low price. The paint film prepared from it has good fullness, strong construction tolerance, and excellent weather resistance. It is widely used in the field of steel structure anti-corrosion coatings. Although the synthesis technology of pure acrylic emulsion and styrene-acrylic emulsion is becoming more and more mature and advanced, from the traditional single-phase polymer synthesis, single-phase / multi-phase, core-shell structure, graft copolymerization and other synthetic technologies have been developed to change the film-forming resin. Molecular structure, but one-component acrylic coatings still have inherent structural disa...
