Abstract

The invention discloses a quick-drying type epoxy primer and a preparation method thereof. The quick-drying type epoxy primer comprises the following components in parts by weight: 30-40 parts of epoxy resin, 0.2-1 part of leveling agent, 4-6 parts of anti-settling agent, 0.1-0.5 part of dispersant, 45-55 parts of pigment and filler, and 1-3 parts of drier. According to the technical scheme of the invention, all the performance indexes of the paint film of the primer completely reach or even exceed the indexes of commercial epoxy primers. At the same time, the quick-drying type epoxy primer is strong in versatility, and the paint film of the primer is quick to dry. Therefore, the coating period is greatly shortened.

Description

technical field [0001] The invention belongs to a general fast-drying epoxy primer, in particular to a solvent-based epoxy primer with an epoxy amine curing system and a preparation method thereof. Background technique [0002] Today's anti-corrosion coatings have become the main force of my country's coating industry, and anti-corrosion coatings, especially heavy anti-corrosion coatings, are widely used in China. Its main application areas include emerging marine engineering, modern transportation, energy industry, large industrial enterprises and municipal facilities. These application areas have very strict requirements on anti-corrosion coatings, and the foundation is particularly important to achieve good anti-corrosion and protection effects. In order for the anti-corrosion coating to play its full role, the primer and intermediate layer selected are particularly important. The existing commercially available anti-rust primers have good versatility, but generally hav...
