preparation example Construction

[0035] The present invention also provides a method for preparing the injection molded zipper element described in the above technical solution, comprising the following steps:

[0036] a) mixing polycarbonate, poly-1,4-cyclohexanedimethylene terephthalate, modification aids and stabilizers to obtain a mixture;

[0037] b) Injecting the mixture obtained in step a) to obtain injection molded zipper elements.

[0038] The invention mixes the polycarbonate, the 1,4-cyclohexanedimethylene terephthalate, the modifying auxiliary agent and the stabilizing agent to obtain the mixture. In the present invention, the polycarbonate, poly(1,4-cyclohexanedimethylene terephthalate), modification aids and stabilizers are the same as those described in the above technical solution, and will not be repeated here. In the present invention, the mass ratio of the polycarbonate, poly-1,4-cyclohexanedimethylene terephthalate, modification aid and stabilizer is preferably (40-60): (40-120) : (0.5-1...

Embodiment 1

[0047] (1) Add 0.5kg polycarbonate, 1kg poly-1,4-cyclohexanedimethylene terephthalate, 0.075kg polyethylene terephthalate and 0.015kg polyethylene wax into the mixer and stir well , and then vacuum-dried at 105°C for 8h to obtain a mixture;

[0048] (2) Inject the above mixture at 260° C. with an injection pressure of 4.5 MPa to obtain transparent injection molded zipper elements.

[0049] The injection-molded zipper element obtained in Example 1 of the present invention was ironed at a high temperature of 130°C for 1 minute, and the product was not deformed, and the test was qualified; at the same time, the injection-molded zipper element obtained in Example 1 of the present invention was treated with carbon tetrachloride In the dry cleaning test, the test time was 30 minutes, and there was no obvious change on the product surface.

Embodiment 2

[0051] (1) Add 0.5kg of polycarbonate, 0.5kg of poly-1,4-cyclohexanedimethylene terephthalate, 0.01kg of polypropylene and 0.01kg of polyethylene wax into a mixer and stir well, and then Carried out vacuum drying for 6h to obtain the mixture;

[0052] (2) Inject the above mixture at 260° C. with an injection pressure of 4.5 MPa to obtain transparent injection molded zipper elements.

[0053] The injection-molded zipper element obtained in Example 2 of the present invention was ironed at 130°C for 1 minute at high temperature, and the product did not deform, and the test was qualified; at the same time, the injection-molded zipper element obtained in Example 2 of the present invention was subjected to carbon tetrachloride In the dry cleaning test, the test time was 30 minutes, and there was no obvious change on the product surface.

Abstract

The invention provides an injection zipper tooth, which is prepared from a mixture prepared from polycarbonate, poly(1,4-cyclohexylene dimethylene terephthalate), a performance additive and a stabilizer; the performance additive is prepared from one or more of polyamide, polypropylene and polyethylene terephthalate; the stabilizer is polyethylene wax. Compared with the prior art, the injection zipper tooth provided by the invention is prepared from the mixture with special components; the components interact to realize a synergy effect; the obtained injection zipper tooth has both better dry cleaning resistance and better high temperature resistance. Experiment results show that the injection zipper tooth provided by the invention is not deformed after being subjected to high temperature ironing at 130 DEG C for 1 minute; and after being tested by carbon tetrachloride dry cleaning, the surface of the injection zipper tooth is not obviously changed.

Description

technical field [0001] The invention relates to the technical field of clothing accessories, in particular to an injection molded zipper element, a preparation method thereof and an injection molded zipper. Background technique [0002] Zipper is an integral part of clothing accessories and is widely used in people's daily clothing. The zipper is composed of chain teeth, sliders, upper and lower stops (front and rear codes) or locking parts, among which the chain teeth are the key parts. A general 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; Engage or disengage. [0003] At present, slide fasteners in the prior art are mainly divided into three categories according to different materials: metal slide fasteners, nylon slide fasteners and resin slide fasteners. Among them, the metal zipper teeth are obtained by pressing copper or aluminum wires through the tooth arrangement machine, and t...
