Problems solved by technology

[0003] People frequently use zippers on clothing during their daily dressing process, and the frequent contact and friction between zipper elements and sliders can easily generate static electricity, causing static electricity hazards, which seriously affect people's wearing health, especially for work. People working in petroleum, chemical, dangerous goods management and other working environments will be more harmful, and even cause serious casualties
At present, most of the materials used to make zipper elements do not have antistatic function, and it is difficult to meet people's higher requirements for zipper performance.

preparation example Construction

[0016] figure 1 It is a process step diagram of the method for preparing an antistatic zipper element according to an embodiment of the present invention; the zipper element is injection molded by a graphene-modified plastic through an injection molding process, and the graphene-modified plastic is copolymerized by graphene and ethylene-octene The material resin is prepared by melt blending, and the preparation method includes the following steps: a) pre-dispersing graphene, b) material mixing and drying, c) melt blending extrusion granulation, d) chain tooth injection molding .

[0017] The antistatic zipper elements mentioned in the present invention are made of graphene-modified plastics. The graphene-modified plastics use ethylene-octene copolymer resin as the matrix, and the graphene is first processed by the solvent pre-dispersion method, and then combined with the twin-screw Preparation by blending extrusion method. Among them, graphene has good thermal conductivity, ...

Embodiment

[0019] The specific preparation method is as follows:

[0020] a) Pre-disperse the graphene, first mix the silane coupling agent KH550 and 80% ethanol solution at a mass ratio of 1:10 to prepare a silane coupling agent solution; then mix a certain amount of graphene and silane coupling agent solution , liquid paraffin and xylene are mixed evenly according to the mass ratio of 1:10:5:5, at a speed of 180r / min

[0021] Mix and stir for 30 minutes; finally, distill under reduced pressure, dry in an 80°C drying oven for 3 hours, and take it out for later use.

[0022] b) Material mixing and drying, first by mass percentage, weigh 5% pre-dispersed graphene, 95% ethylene-octene copolymer resin; then mix dimethyl silicone oil and ethylene-octene copolymer resin Put it into a 500r / min high-speed mixer at a mass ratio of 1:10 and pre-mix for 2 minutes; then add graphene and continue mixing for 3 minutes, then take out the material; finally put the material in an 80°C drying oven to dr...

Abstract

The invention provides antistatic zipper teeth and a preparation method thereof. The zipper teeth are obtained by carrying out injection moulding on a graphene modified plastic through an injection moulding process. The graphene modified plastic is prepared by carrying out melt-blending on graphene and ethylene-octene copolymer resins. The preparation method comprises the following steps: a) carrying out pre-dispersing treatment on graphene, b) subjecting materials to mixing and drying, c) carrying out melt-blending and extrusion-granulating, and d) carrying out injection molding to obtain zipper teeth. The antistatic zipper teeth are unique in material selection and simple in preparation. Through careful material proportioning and reasonable process arrangement, better antistatic performance is realized, and people's higher wearing demand is satisfied.

Description

technical field [0001] The invention relates to a zipper element, in particular to an antistatic zipper element and a preparation method thereof, belonging to the technical field of zippers. Background technique [0002] Zipper is an important livelihood product, widely used in clothing, bags, shoes and other daily necessities. The zipper is composed of chain teeth, sliders, cloth belts, etc. Generally, the zipper has two chain belts, and each chain belt has a row of chain teeth, and the two rows of chain teeth are arranged alternately; the slider clamps the chain teeth on both sides. The pull tab slides to make the chain teeth on both sides mesh or disengage. According to different materials, zippers are mainly divided into three categories: metal zippers, nylon zippers and resin zippers. With the development of the garment industry and the continuous improvement of people's living standards and quality, people's requirements for the performance of zipper products are als...
