High solid content anticorrosive paint used on steel structure surfaces, and spraying method thereof

Abstract

The invention discloses a high solid content anticorrosive paint used on steel structure surfaces, and a spraying method thereof. The high solid content anticorrosive paint used on steel structure surfaces comprises epoxy resin, a pigment filler, aluminum-zinc alloy powder, a silane coupling agent, an active diluent, a corrosion inhibitor, an auxiliary agent, a curing agent, and acrylic acid. Thespraying method comprises following steps: 1, steel structure surface treatment; 2, primary spraying; 3, low temperature roasting; 4, secondary spraying; 5, low temperature roasting; and 6, drying curing molding. The formula design of the high solid content anticorrosive paint is scientific and reasonable; no toxic or harmful ingredient is used; solvent content is low; volatility is low; the highsolid content anticorrosive paint is safe, and is friendly to the environment; no pollutant such as waste water or smoke is generated in spraying process, three wastes discharge is reduced; layered low temperature roasting pre-curing is adopted, so that curing temperature is reduced effectively, and energy consumption is reduced effectively. The high solid content anticorrosive paint and the spraying method are safe, are friendly to the environment, are capable of saving energy and reducing discharge, and are promising in market prospect.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a high-solid anti-corrosion coating for steel structure surfaces with energy saving and pollution reduction and a spraying method thereof. Background technique [0002] Corrosion is the main cause and form of failure of metal steel components, and the resulting economic losses are staggering. Anti-corrosion coating protection is the main means to improve the corrosion resistance of rigid structural parts. At present, there are many varieties of anti-corrosion coatings, such as water-based anti-corrosion coatings, powder anti-corrosion coatings, radiation curing coatings, etc. These coatings either contain a large amount of volatile solvents, or contain toxic components, such as lead, hexavalent chromium, etc., or construction The process is complex. Using the traditional hot-dip plating process, a certain amount of waste water, acid mist, etc. will be generated during th...

At present, there are many varieties of anti-corrosion coatings, such as water-based anti-corrosion coatings, powder anti-corrosion coatings, radiation curing coatings, etc. These coatings either contain a large amount of volatile solvents, or contain toxic components, such as lead, hexavalent chromium, etc., or construction The process is complex. Using the traditional hot-dip plating process, a certain amount of waste water, acid mist, etc. will be generated during the construction process, polluting the environment, and the temperature of hot-dip plating is generally between 480 and 560°C. The temperature is high and there is energy consumption. Defects such as large, environmental pollution and the decrease in stiffness of components after immersion plating
