Abstract

The invention discloses an anticorrosion alkyd resin powder coating for a steel structure. The anticorrosion alkyd resin powder coating comprises the following raw materials in parts by weight: 10-20 parts of styrene modified alkyd resin, 30-45 parts of phenolic epoxy resin, 15-30 parts of semi-drying oil alkyd resin, 1-2 parts of 2-ethyl-4-methylimidazole, 0.4-0.9 parts of triethanolamine, 0.5-1 parts of N-diglycidyl aniline, 1-3 parts of 2-phenylimidazoline, 0.5-1.4 parts of gamma-glycidoxypropyltrimethoxysilane, 1-2 parts of an aluminum-zirconium coupling agent, 0.5-1.8 parts of stearate, 1-2 parts of chlorinated paraffin, 1-2 parts of a polyacrylic acid-2-ethylhexyl acrylate leveling agent, 1-2 parts of acrylate, 8-12 parts of modified sphere silicon fine powders, 10-14 parts of sepiolite powders, 5-10 parts of nano carbon, 3-8 parts of nano-titania and 1-4 parts of ammonium dihydrogenphosphate. The anticorrosion alkyd resin powder coating provided by the invention has good weather resistance and excellent heat resistance.

Description

technical field [0001] The invention relates to the technical field of alkyd resin coatings, in particular to an anticorrosive alkyd resin powder coating for steel structures. Background technique [0002] Corrosion of steel structures is a phenomenon in which the metal surface of steel structures is destroyed by the influence of environmental media. At present, the most effective method of anti-corrosion is to coat the metal surface with an anti-corrosion coating to isolate it from corrosive media. Alkyd resin has the advantages of good leveling of the coating film, good adhesion to metal substrates, high hardness of the paint film, and good scratch resistance, so it is widely used in metal anti-corrosion, but the weather resistance of alkyd resin coating film is currently Poor performance and poor heat resistance. Contents of the invention [0003] The invention provides an anticorrosive alkyd resin powder coating for steel structures, which has good weather resistance ...
