Abstract
A water-proof zipper comprises a slider (1), zipper tapes (3) and zipper teeth (2), wherein the zipper teeth (2) include an engagement part (2-1) and a connection part (2-2); each of the zipper tapes (3) includes a connection part (3-1) and a transition part (3-2); the engagement part (2-1) of the zipper teeth (2) forms teeth capable of being engaged with each other; the connection part (2-2) of the zipper teeth (2) is embedded in the connection part (3-1) of the zipper tapes (3); cross-linking agents are filled in the gap of teeth of the connection part (2-2) of the zipper teeth (2); the transition part (3-2) of the zipper tapes (3) is tightly combined with a TPU layer through cross-linking agents; the TPU layer covers the whole zipper teeth (2) including the engagement part (2-1); and a notch (2) which is compactly matched with the shape of the front of the slider (1) is disposed at one end of the zipper. The water-proof zipper has optimum water-proof performance, and is water-proof without blind angle.
Description
Technical field
The utility model relates to the slide fastener technical field, a kind of specifically waterproof slide fastener.
Background technology
Normally used waterproof slide fastener, the chain belt that generally adopts the rubber material to make, the outer TPU (TPUE) that covers of sprocket, waterproof effect is played by TPU in sprocket engagement back.This chain is made difficulty, and the water resistance instability, and hydraulic pressure resistance power is difficult to guarantee.This mainly is because sprocket is generally made by nylon material, and chain belt generally to be polyester material make, PTU can finely combine with sprocket, but is difficult to guarantee good combination with chain belt, when hydraulic pressure drainage can occur greatly the time.And the waterproof of slide fastener end also is insoluble all the time problem.The utility model proposes a kind of air-tight water-proof slide fastener with good water resistance at the defective of above-mentioned existing slide fastener, can be widely used in military project, national defence, Aeronautics and Astronautics and chemical industry.
Summary of the invention
The utility model proposes a kind of novel waterproof slide fastener.Comprise pull head, chain belt and sprocket, sprocket comprises engaging piece and connecting portion, chain belt comprises connecting portion and transition part, the engaging piece of sprocket forms can intermeshing sprocket, the connecting portion of sprocket is entrenched on the connecting portion of chain belt, the backlash of the connecting portion of sprocket is filled with crosslinking agent, and the transition part of chain belt is combined closely by a crosslinking agent and a TPU layer, and described TPU layer covers the whole sprocket of the engaging piece that comprises sprocket.
Slide fastener one end setting can with the fine and close recess that cooperate of pull head front shape.When pull head was moved the slide fastener end to, the pull head front portion can embed in this recess, therefore formed the end sealing of slide fastener.
Described crosslinking agent for example adopts organic dibasic acid, polyalcohol etc.; Or molecule contains the compound of a plurality of unsaturated double-bonds, as divinylbenzene and vulcabond etc.
The waterproof slide fastener of the utility model pin has best water resistance, and the slide fastener waterproof does not have the dead angle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a slide fastener cutaway view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The utility model proposes a kind of novel waterproof slide fastener.Comprise pull head 1, chain belt 3 and sprocket 2, sprocket 2 comprises engaging piece 2-1 and connecting portion 2-2, chain belt 3 comprises connecting portion 3-1 and transition part 3-2, the engaging piece 2-1 of sprocket 2 forms can intermeshing sprocket, the connecting portion 2-2 of sprocket 2 is entrenched on the connecting portion 3-1 of chain belt 3, the backlash of the connecting portion 2-2 of sprocket 2 is filled with crosslinking agent, and the transition part 3-2 of chain belt 3 combines closely by a crosslinking agent and a TPU layer 4, and described TPU layer 4 covers the whole sprocket 2 that comprises engaging piece 2-1.
Slide fastener one end setting can with the fine and close recess 5 that cooperate of pull head 1 front shape.When pull head 1 was moved the slide fastener end to, pull head 1 front portion can embed in this recess 5, therefore formed the end sealing of slide fastener.
Described crosslinking agent for example adopts organic dibasic acid, polyalcohol etc.; Or molecule contains the compound of a plurality of unsaturated double-bonds, as divinylbenzene and vulcabond etc.
