Abstract

The present invention relate to the field of aqueous primer, especially relates to a heavy metal-free aqueous epoxy primer and a preparation method thereof. The finish paint is composed of a componentA and a component B, and comprises that following raw materials: aqueous epoxy emulsion, substrate wetting agent, pigment, filler, antirust pigment, defoamer, dispersant, cosolvent A, antiflashover agent, deionized water, thickener, epoxy resin curing agent and cosolvent B. The topcoat can reduce the use of auxiliary materials containing organic solvents through the selection of the types and amounts of various components, thereby greatly reducing the VOC content, avoiding the adverse effects of a large number of toxic volatiles on human health and the environment, and being more environmentally friendly. At the same time, the film has excellent anticorrosion performance and toughness, which can meet the anticorrosion requirements of marine engineering, modern transportation, energy industry, large industrial enterprises, municipal facilities and so on.

Description

technical field [0001] The invention relates to the field of water-based primers, in particular to a heavy metal-free water-based epoxy primer and a preparation method thereof. Background technique [0002] Marine engineering, modern transportation, energy industry, large-scale industrial enterprises, municipal facilities, etc. are usually used in open-air environments or in corrosive environments such as acids, alkalis, and salts, which require high anti-corrosion performance of coatings. At present, domestic anti-corrosion coatings are generally solvent-based coatings, such as solvent-based alkyd system coatings, epoxy ester system coatings or epoxy system coatings. Solvent-based paints contain a large amount of toxic organic volatiles, which will volatilize in large quantities during production or painting, and will continue to volatilize slowly after painting, posing a threat to the atmospheric environment and human health. Under the pressure of the national environment...
