Abstract

The invention relates to a technical field of waterproof coatings for zippers, and particularly relates to a polyamide flashing waterproof coating for zippers and a preparation method of the waterproof coating. The waterproof coating comprises an acrylic prepolymer emulsion, polyamide-flashing microbeads, active diluting monomers, a photoinitiator, a leveling agent, an ultra-violet shielding agentand deionized water, wherein the polyamide-flashing microbeads are composed of flashing microbeads and polyacrylamide layers coating the flashing microbeads. According to the invention, polyacrylamide is used to coat the flashing microbeads, so that the flashing microbeads can be evenly dispersed in the deionized water, and a coating layer can have good tensile strength and bending strength and high ornamental value. In addition, the polymerization of the photoinitiator, an acrylic prepolymer, a polyacrylamide layer and the active diluting monomers are utilized, so that a stable cross-linkingstructure is formed, and the prepared acrylic coating has good waterproof property and mechanical properties.

Description

technical field [0001] The invention relates to the technical field of zipper waterproof coatings, in particular to a polyamide flash waterproof coating used for zippers and a preparation method thereof. Background technique [0002] A zipper is a connecting piece that relies on continuously arranged chain elements to merge or separate items. It is now widely used in clothing, bags, tents, etc. As an important part of carrying chain teeth and other zipper components, the zipper bag will also have a great impact on the overall appearance of the garment. The existing zipper tapes have a single way of expression, generally only for simple color expression, and dyeing is also easy to cause problems such as fading and fading. [0003] In order to meet the needs of pursuing fashion and individuality, it is popular to add gold and silver onion powder to viscous fluids or liquid adhesives such as hairspray, personalized clothing spray glue, nail polish, etc., in order to achieve a ...
