Abstract

The invention relates to a quick-drying water-based anticorrosive paint and a preparation method thereof, belonging to the technical field of water-based paints. The paint is prepared from the following components in parts by weight: 16 to 40 parts of epoxy ester resin; 3 to 10 parts of quick-drying acrylic resin; 1-8 parts of acrylic resin with high glass transition temperature; 0.2-0.6 part of awater-based organic silicon defoamer, 0.3-1.5 parts of a leveling agent, 0.5-1.5 parts of a base material wetting agent, 5-15 parts of a coalescing agent, 10-20 parts of an inorganic filler, 1-8 parts of an antirust filler, 8-15 parts of distilled water I, 10-20 parts of distilled water II, 0-1 part of a thickener and 0.3-2 parts of a neutralizer. The water-based paint disclosed by the inventionis high in paint film drying speed, high in hardness and convenient to construct, and has an excellent anti-corrosion effect.

Description

technical field [0001] The invention belongs to the technical field of water-based paint, in particular to a quick-drying water-based anti-corrosion paint and a preparation method thereof. Background technique [0002] Water-based industrial paint is an environmentally friendly industrial paint. Its low VOC emissions reduce air pollution, reduce the possibility of explosions and fires, and greatly improve construction safety. At present, antirust primers for steel structures mainly include alkyd, epoxy ester, acrylic and other types. Alkyd and epoxy ester primers have the advantages of good anti-corrosion performance, but they have a strong odor, slow surface drying speed, and low hardness, which are difficult to meet the needs of large-scale flow operations for rapid packaging; while acrylic anti-rust primers appear to be It dries quickly, but its weather resistance is poor, and its anti-corrosion performance is poor, so it cannot achieve long-term anti-corrosion. Conten...
