Abstract

The invention discloses an aqueous PU self-curing paint and a preparation method thereof. The paint is prepared by blending the following components according to a certain ratio: aqueous hydroxyl acrylic acid emulsion, TeGo270 wetting agent, TeGo822 antifoaming agent, AMP95, TeGo4100 flatting agent, carbitol acetate, dipropylene glycol-butyl ether, anionic water, BYK425 polyurethane rheological aid, flash-rust inhibitor, aqueous hydroxyl acrylic acid emulsion, TeGo270 wetting agent, TeGo760 wetting dispersant, organic silicon wear-resistant powder (UNI CONE T-2050), and aqueous resin-free color paste. The paint has the characteristics that the properties of formed paint film are good, the drying speed is quick; solved are the problems that rust can easily grow on the metal substrate, which is covered by a conventional aqueous paint and the drying of conventional aqueous paint is slow; the content of VOC (volatile organic compound) is low, and the paint is safe and environment-friendly. The paint can be used to protect metal substrates, which have high environment protection requirements, such as automobile parts, machinery equipment, bridges, steel structure, net rack, and the like.

Description

technical field [0001] The invention relates to a paint, in particular to a protective coating water-based paint applied to metal substrates such as automobile spare parts, mechanical equipment, bridges, steel structures, grid frames and the like which have high requirements on environmental protection and performance. Background technique [0002] Common water-based paints have comprehensive performance and convenience. Although different brands of water-based paints have breakthrough features, they also have various defects. Some paint films have insufficient fullness and high gloss, and some have poor color development and flow Not flat enough, some have poor scratch resistance, high hardness and excellent chemical resistance, some have poor weather resistance, gloss and color retention, anti-aging, and salt spray resistance, and some require special dispersion media and Thinner, construction is inconvenient, flammable and explosive; and generally there are problems of ea...
