Problems solved by technology

However, the existing waterproof coatings have the following problems: 1. The formed coating has poor stretchability and toughness. In the process of repeated bending of the zipper tape, the coating is easy to crack, which affects the texture of the clothing; 2. Most of the existing waterproof coatings are solvent-based coatings, and there are very few water-based coatings, and generally water-based coatings do not perform well in water resistance, so the zipper will not be washable.

Abstract

The invention relates to the technical field of waterproof coatings of zippers, in particular to a waterproof acrylic coating for a zipper and a preparation method thereof. The waterproof acrylic coating comprises acrylic prepolymer emulsion, complex fiber, active diluent monomer, photoinitiator, flatting agent and deionized water, wherein the complex fiber is composed of a nanocellulose filamentand a polyacrylamide layer coated with the nanocellulose filament. The waterproof acrylic coating for the zipper and the preparation method thereof have the advantages that coating modification is carried out on the nanocellulose filament through the polyacrylamide layer, so that the nanocellulose filament can have a stable suspension property in the coating, thereby being conductive to the dispersion of the nanocellulose filament in the coating, carbon-carbon double bonds of the polyacrylamide layer can also be subjected to polymerization reaction with the active diluent monomer and an acrylic prepolymer under the action of a photoinitiator, the dispersion stability of the complex fiber is further improved, and the coating can have good stretchability, tenacity and waterproofness.

Description

Technical field[0001]The invention relates to the technical field of zipper waterproof coatings, in particular to a waterproof acrylic paint for zippers and a preparation method thereof.Background technique[0002]Zipper is a connecting piece that relies on continuously arranged chain teeth to merge or separate items. It is now widely used in clothing, bags, tents, etc. Nowadays, there are many kinds of zippers, and some functional clothing, such as jackets, need to have a waterproof effect. In the existing zipper clothing, due to the water absorption of the fiber, water easily penetrates from the zipper tape, which results in the limitation of the application of the zipper on the waterproof clothing.[0003]Applying waterproof paint on the zipper tape to form a waterproof layer is one of the methods that can improve the waterproofness of the zipper tape. However, the existing waterproof coatings have the following problems: 1. The formed coating does not perform well in stretchability ...
