Abstract

The invention relates to the technical field of waterproof paint for zippers and in particular relates to polyurethane flash waterproof paint for zippers and a preparation method of the polyurethane flash waterproof paint. The waterproof paint comprises polyether polyol, isocyanate, polyamide-flash beads, a chain extender, a catalyst, an active diluent monomer, a photoinitiator, a flatting agent and deionized water, wherein the polyamide-flash beads are composed of flash beads and a polyamide layer coating the flash beads. According to the waterproof paint disclosed by the invention, the flashbeads are coated by adopting the polyamide, so that the flash beads are uniformly dispersed in deionized water. The polyamide layer has many hydroxide radicals and can perform cross-linking polymerization with isocyanate, carbon-carbon double bonds in the polyamide layer can also carry out a polymerization reaction with the active diluent monomer, so that the stability of the polyamide-flash beads in the paint is improved. The coating can achieve excellent waterproof property and mechanical property, and the ornamental value is high.
