Embodiment 1

[0043] Pre-setting the nylon zipper chain belt at 180°C, the setting shrinkage rate is controlled at 3%, and then dyed according to the common process of polyester zipper, and it is ready to use after dyeing;

[0044] Weigh the two-component liquid silica gel A component, B component, reinforcing agent, polymerization inhibitor, color paste, and stir them evenly. Each component weight content is as follows respectively:

[0045] BD-836A component 100 parts;

[0046] BD-836B component 90 parts;

[0047] 3 parts of color paste;

[0048] 30 parts of MQ resin reinforcing agent;

[0049] Two-component liquid silica gel A component and B component weight and 0.1% dienyl maleate inhibitor;

[0050] Apply the above mixture to one side of the zipper tape by roller coating or scraping, with a coating thickness of 200um, and then put it into a 120°C oven for 30 minutes of vulcanization, and then cure it at 80°C for 24 hours. Then cut the waterproof membrane along the midline for rea...

Abstract

The invention discloses a processing method of a waterproof zipper. The processing method comprises the following steps: shaping a zipper chain belt to obtain a flat chain belt; dyeing: dyeing the flat chain belt to obtain a dyed chain belt; preparing materials: weighing 90-100 parts of two-component liquid silica gel A component, 90-100 parts of two-component liquid silica gel B component, 0-6 parts of color paste, 10-70 parts of reinforcing agent and a polymerization inhibitor by 0.1% of the weight sum of the two-component liquid silica gel A component and the two-component liquid silica gel B component, and uniformly stirring to obtain a mixed material; coating the mixed material on one side or two sides of the dyed chain belt, and then vulcanizing and curing to obtain the chain belt with a waterproof film; gashing the waterproof film along a middle line of the chain belt, and then assembling a puller, an upper / lower stopper or a square pin, so as to obtain the waterproof zipper. The waterproof zipper processed by the method disclosed by the invention has the anti-fouling and anti-splashing performance and greater high-temperature resistance. In addition, the process is simpler.

Description

technical field [0001] The invention relates to the technical field of slide fasteners, in particular to a waterproof slide fastener and a processing method thereof. Background technique [0002] Due to the gradual popularity of outdoor sports, the application of special functional products such as water repellent is becoming more and more extensive. As a clothing accessory, zippers also need to meet special requirements in special clothing and other products. It is required that the zipper can be water-repellent as a whole, especially the cloth belt. [0003] At present, the water-repellent zippers on the market are usually coated with a layer of resin film, such as PU, TPU, etc., or coated with a layer of resin to form a water-repellent layer. [0004] The water-repellent zipper formed by film or coating technology is easy to be polluted when it is in contact with contrasting color fabrics or exposed to outdoor use due to the adsorption of PU, TPU and other resins, especi...
