Abstract
The invention relates to a hyperbranched modified alkyd resin water-based anticorrosive paint which comprises the following components in parts by weight: 50.0-80.0 parts of hydroxypropyl distarch phosphate modified waterborne alkyd resin, 1.0-20.0 parts of filler, 1.0-3.5 parts of auxiliary agent, 2.0-10.0 parts of sodium sulfate type transparent powder, 0.1-0.6 part of carboxymethyl chitosan, 2.5-5.0 parts of antifreezing agent and 5.0-20.0 parts of deionized water; the hydroxypropyl distarch phosphate modified waterborne alkyd resin consists of vegetable oleic acid, hydroxypropyl distarch phosphate, terephthalic acid, azelaic acid, organic acid anhydride, polyhydric alcohol, dimethylolpropionic acid, mixed solution, dibutyltin dilaurate, a neutralizer, polyacrylamide and deionized water; the hyperbranched modified alkyd resin water-based anticorrosive coating prepared by the invention does not need an additional anticorrosive additive and anti-sagging additive, and has the characteristics of good corrosion resistance, anti-sagging performance, quick drying, good adhesive force, high fullness and the like.
Description
Technical Field
The invention relates to a modified alkyd resin coating, in particular to a hyperbranched modified alkyd resin water-based anticorrosive coating, and belongs to the technical field of water-based functional coatings.
Background
The alkyd resin coating has the characteristics of high gloss, fullness, low price, easily available raw materials and the like. But the coating film is softer, water-resistant, slower in drying speed, poor in alkali resistance, poor in adhesion to some materials and poor in corrosion resistance, and is easy to generate sagging during construction; the application of alkyd resin coatings is greatly limited, and many existing alkyd resin coatings adopt a mode of adding corresponding auxiliary agents or materials in order to achieve the desired performance, but the mode can improve the performance, but easily causes the defects of poor compatibility, easy separation, influence on storage performance and the like.
