Wherein: 1 is upper cover; 2 is last ending; 3 is the polyurethane base cloth; 4 is pull head; 5 is chain; 6 for ending down; 7 is low head; 8 is draw ring; 9 stumble for drawing.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
Referring to Fig. 1,2, a kind of polyurethane water vapor seal zipper comprises polyurethane base cloth 3, chain 5, pull head 4, upward ends 2, ends 6 down, upper cover 1 and low head 7; Described chain 5 intercouples and constitutes by being fixed on sprocket on the polyurethane base cloth 3; Described chain 5 upper ends and upward end 2 and be fixed on the upper cover 1 by injection molding way; Described chain 5 lower ends and end down 6 and be fixed on the low head 7 by injection molding way; Described chain 5 is provided with pull head 4.
Described polyurethane base cloth 3 is high-strength polyester or polyamide fibre chemical fabric, and polyurethane base cloth 3 thickness are 2.3mm, 3mm or 3.9mm.
Described polyurethane base cloth 3 upper surfaces are provided with the polyurethane laminate that thickness is 0.05mm, 0.1mm, 0.6mm or 0.8mm; Described polyurethane base cloth 3 lower surfaces are provided with the polyurethane laminate that thickness is 0.03mm, 0.1mm, 0.5mm or 0.7mm; Described polyurethane laminate adopts calendering, be coated with and scrape or compound mode is arranged on polyurethane base cloth 3 upper surfaces and polyurethane base cloth 3 lower surfaces.
Describedly go up to end 2, end 6 down, the material of upper cover 1 and low head 7 is polyurethane plastics.
Described pull head 4 is provided with draw ring 8; Described draw ring 8 is provided with to draw stumbles 9.
A kind of preparation method of polyurethane water vapor seal zipper, according to following steps:
(1) preparation polyurethane base cloth 3: polyurethane plastic is set on the two sides of high-strength polyester or polyamide fibre chemical fabric obtains polyurethane base cloth 3;
(2) at dress chain 5 on the base cloth: on two polyurethane base cloths 3, take on monolateral chain 5 respectively with the toothing machine earlier, then two monolateral chain 5 usefulness pull heads 4 are merged into slide fastener;
(3) preparation polyurethane water vapor seal zipper: polyurethane plastics is placed on slide fastener upper end in the step (3), and suppresses in the slide fastener upper end by injection machine and to end 2 and upper cover 1; Polyurethane plastics is placed on slide fastener lower end in the step (3), and suppresses in the slide fastener lower end by injection machine and to end 6 and low head 7 down; Obtain polyurethane water vapor seal zipper.
Two sides at high-strength polyester or polyamide fibre chemical fabric, roll respectively or be coated with and scrape or the composite polyurethane resin molding makes it become adhesive plaster, on the toothing machine, take on monolateral chain 5 with this polyurethane adhesive plaster and sprocket then, then two monolateral chain 5 usefulness slider of zipper fasteners are merged into water vapor seal zipper, according to the Len req severing, with special mould shutoff slide fastener two ends on injection machine.So far polyurethane water vapor seal zipper has just created.The most principle of domestic existing water vapor seal zipper is close or identical, and used base cloth is rubberized fabric, and slide fastener itself can not use separately again, can only become the pith of downstream product; Rubber-based cloth slide fastener poor performance of the prior art, poor, the certain pollution of production existence of manufacturability are so researched and developed polyurethane water vapor seal zipper.Its base cloth polyurethane adhesive plaster, the oil resistivity of slide fastener, cold resistance, wearability, flexibility, manufacturability, the feature of environmental protection, technology vestige aesthetic property, production efficiency height all are that other slide fasteners can not be compared.
The invention has the advantages that:
(1) properties of product of water vapor seal zipper significantly improve: the aesthetic property of slide fastener intensity, sealing, oil resistivity, cold resistance, flexibility, wearability, manufacturability, the feature of environmental protection, downstream product, all significantly improve in various degree.
(2) production efficiency significantly improves: existing rubberized fabric pressure-sealing zipper shutoff two is to adopt sulfuration process, and one of shutoff just needs more than 20 minute, and the slide fastener of polyurethane adhesive plaster only needs about 15 seconds with one of injection technique shutoff, and effect improves 10 times to put on.
(3) slide fastener overall appearance quality height, regular shape, cleanliness factor height.
(4) noresidue bubble, cutter trade is attractive in appearance.
(5) do not use chemical solvent, non-environmental-pollution in process of production.
(6) process choice is strong, and for the slide fastener producer, technology becomes simple and grasps easily.For the downstream product producer, promptly can select heat seal process, also can select technique for sticking.
Above content is to further describing that the present invention did in conjunction with concrete preferred implementation; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of being submitted to.
