Abstract

The invention relates the nanometer modified metallic anti-corrosive paint, comprising 50-70wt% host crystal, 20-40wt% curing agent and 1-10wt% oxide addition. The host crystal comprises compound resin, color paste and auxiliary agent, and the curing agent comprises 75% aromatic isocyanate, 75% aliphatic isocyanate, dimethylbenzene, butyl acetate optal and 2-butanol. The invention adds nanometer oxidate to improve the quality of anti-corrosive paint, and adds alcohols solvent in host crystal to reduce noxious constituents in solvent. The invention doesn't use the compounds which contain lead and chromium.

Description

technical field [0001] The invention relates to the technical field of metal coatings, in particular to a special metal anti-rust finish paint, which is mainly used for corrosion and anti-rust coating on the surface of mechanical equipment and metal structural parts, especially suitable for mechanical equipment, injection molding machines, die-casting machines, Protective and decorative coating for spark machines, CNC machining centers, air compressors, elevators, motors and other equipment and manufacturing industries. Background technique [0002] At present, most of the existing anti-corrosion and anti-rust paints are solvent-based paints, and their solvents are generally based on benzene organic solvents such as xylene, which are used as diluents for pigments, paints, etc., and their content is relatively high. Xylene is a colorless and transparent liquid, insoluble in water, soluble in ethanol and ether, toxic, volatile, can pollute air and environment, and seriously en...
