Problems solved by technology

[0002] With the change of people's living standards and aesthetic views, various styles of clothing and bags appear. Zippers are common accessories for clothing and bags. The styles and performance of zippers are also constantly enriched. Divided into nylon zippers, resin zippers and metal zippers, among them, resin zippers are more and more popular due to their strong practicability, low price, and various colors and styles. Nylon zippers and metal zippers are prone to sprocket looseness, but after long-term use, they will also be worn out and the opening and closing will not be smooth, thus affecting the service life of the zipper
[0003] The existing patent document CN106307836A discloses a luminous resin zipper, which specifically discloses that the zipper includes a chain, a slider, a base belt, an upper stop, a lower stop and a plug block. Composed of mutually meshing chain teeth, the upper stop, lower stop and latch blocks are respectively arranged on the open end and the closed end of the chain, the slider is arranged on the zipper, and the main raw material of the chain is engineering plastics , which adds a certain amount of luminous powder and related auxiliary materials; the main raw materials of the chain are composed of polyoxymethylene resin, luminous powder and auxiliary agents; therefore, the zipper prepared by the patent document is only the chain with fluorescence, and the strength of the zipper chain prepared is Low, easy to wear after a period of use, affecting the use of the zipper; therefore, it is necessary to improve the strength and wear resistance of the zipper to ensure the smooth opening and closing of the zipper during use, and improve the practicability of the resin zipper

Abstract

The invention mainly relates to the technical field of garment accessory processing, and discloses a preparation method of a high-strength wear-resistant noctilucent zipper. The preparation method comprises the following steps: preparation of modified polyamide, preparation of modified polyethylene wax, primary mixing, secondary mixing, injection molding and accessory mounting. According to the preparation method of the high-strength wear-resistant noctilucent zipper provided by the invention, the prepared zipper is high in strength and wear resistance, and abrasion and displacement of the zipper can be avoided after the zipper is used for a long time; smooth opening and closing of the zipper can be kept, and the service life of the zipper is prolonged; and in addition, the zipper has a noctilucent effect, the design is unique, and the style is novel, so that an obvious decoration effect be achieved, travel safety can be improved due to the noctilucent effect at night, and practicability of the zipper is improved. Diphenyl silanediol, tetraethyl orthocarbonate and calcium titanate are added into fused polyamide in sequence, and full heat-preservation stirring is carried out for modifying the polyamide, so that strength and wear resistance of the polyamide can be improved, and wear resistance of the zipper is enhanced.
