Water-based acrylate antirust resin and preparation method thereof

The invention discloses water-based acrylate antirust resin and a preparation method thereof. A polymer chain of the water-based acrylate antirust resin contains groups such as pyrano [2, 3-c] pyrazolyl, tertiary amine, phosphate, cyano, long-chain octadecyl and isobornyl, so that flash rust on the metal surface can be effectively inhibited, and the salt spray resistance is good; after being dried, the water-based acrylate anti-rust resin has good adhesion to a base material, water resistance, impact resistance, scratch resistance and coating toughness and high glossiness, and a good anti-rust effect can be achieved without additionally adding anti-rust pigments and fillers. The water-based acrylate antirust resin can also be mixed with conventional water-based resin for use, and is added at any stage of paint mixing, so that the early-stage flash rust resistance and the later-stage continuous rust resistance of the conventional water-based resin can be obviously improved. 本发明公开了一种水性丙烯酸酯防锈树脂及其制备方法。所述水性丙烯酸酯防锈树
