Abstract

The present invention relates to the technical field of zippers, in particular to a flash waterproof zipper, which includes a cloth tape and a number of fastener elements arranged on the cloth tape, and a flash waterproof coating is compounded on the cloth tape, and the flash waterproof coating is composed of Flash waterproof paint is made, and described flash waterproof paint comprises as raw material: polyol, polyacrylamide-glitter microbead, isocyanate curing agent, catalyst, chain extender, leveling agent, wetting agent and deionized water, so The polyacrylamide-glitter microbeads are composed of glitter microbeads and a polyacrylamide layer covering the glitter microbeads. In the present invention, by using polyacrylamide to coat the glitter microbeads, the glitter microbeads can be uniformly dispersed in deionized water and cross-linked with isocyanate to polymerize, thereby improving the stability of the polyacrylamide-glitter microbeads in the coating, The coating can have good mechanical properties and water resistance, and the zipper has strong durability and high ornamental value.

Description

technical field [0001] The invention relates to the technical field of zippers, in particular to a flash waterproof zipper. 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 shiny effect and earn the visual effect of other people's eyes. . Therefore, i...
