Title:
HIGHLY CORROSION-RESISTANT, WATER-SOLUBLE ANTI-RUST COATING SOLUTION
Document Type and Number:
WIPO Patent Application WO/2021/015339
Kind Code:
A1
Abstract:
One embodiment of the present invention provides a water-soluble, anti-rust coating composition comprising: an acrylic resin; zinc flakes; aluminum flakes; a dispersant; an antirust additive; ionized water or a water-soluble solvent; a surface modifier; and a pH adjusting agent, wherein the acrylic resin is produced by: condensation-polymerizing an unsaturated fatty acid and an epoxy resin silane to comprise a molecular chain forming a structure in which a polybasic acid, a polyhydric alcohol, and an epoxy are condensation polymerized, and a molecular side chain forming a structure in which an unsaturated fatty acid and a silane are condensation polymerized in a polyhydric alcohol; cooling the condensation polymerization reaction product and then adding and reacting a water-soluble polybasic acid to incorporate a water-soluble polybasic acid in the molecular side chain and thereby produce a water-soluble epoxy or alkyd resin intermediate; and polymerizing the water-soluble epoxy and the alkyd resin intermediate with at least one type of radically reactive acrylic monomer at a temperature in the range of 60-160°C.
