Abstract
The utility model provides a waterproof zipper with good water resistance and strong water pressure resistance. The waterproof zipper includes two woven belts, two rows of zipper teeth and a puller; one side of the two rows of zipper teeth is respectively and fixedlyarranged on each woven belt and extend along the length direction; the other sides of the two rows of zipper teeth can be arranged in a separable engaging way; the puller can be arranged on the engaged part of the two rows of zipper teeth in a sliding way for opening or closing the engaging state of the two rows of zipper teeth; the same side of the two woven belts is respectively provided with a layer of thermoplastic polyurethane resin; and the two layers of thermoplastic polyurethane resin are arranged at the mutually contacted part of the engaging part of the zipper teeth.
Description
Technical field
The utility model relates to a kind of waterproof slide fastener, is a kind of in the slide fastener.
Background technology
Normally used waterproof slide fastener, generally comprise two straps, two row's chain teeth, pull head and watertight composition, described two straps are arranged side by side, one side of two row's chain teeth is fixedly arranged on respectively on each strap, the opposite side engagement of two row's chain teeth is provided with, pull head is higher than on two row's chain teeth slidably, and watertight composition is located at the same side of two straps.The weak point of this waterproof slide fastener is, though watertight composition and chain tooth can be fitted preferably, but it is not very tight fitting between watertight composition and the strap, drainage can occur when hydraulic pressure is big like this, and the waterproof of slide fastener end also is insoluble all the time problem.
The utility model content
The purpose of this utility model provides a kind of good waterproof performance, waterproof slide fastener that hydraulic pressure resistance is strong.
The technical scheme that the utility model adopted is such: a kind of waterproof slide fastener, comprise two straps, two row's chain tooth and pull heads, one side of described two row's chain teeth is fixedly arranged on respectively on each strap and respectively extends along its length, the separable engagement setting of opposite side of described two row's chain teeth, the mate that pull head is located at two row's chain teeth slidably is used for unlatching or closes two row's chain tooth engagements, the same side that is positioned at two straps is respectively equipped with one deck TPU, and this two layers of thermoplastic polyurethane resin is positioned at chain tooth mate and is in contact with one another setting.
Above-mentioned waterproof slide fastener is filled with crosslinking agent between described strap of each chain tooth and strap coupling part and TPU.
Above-mentioned waterproof slide fastener, a vertical side that is positioned at strap are provided with the slot to make way that the chain tooth holds pull head when closed, and the described two layers of thermoplastic polyurethane resin contact that is positioned on the slot to make way is provided with.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: by the TPU that is in contact with one another in the strap arranged outside, and be provided with crosslinking agent and slot to make way between this TPU and the strap, guarantee that this slide fastener has good watertightness performance, TPU is tightr by the strain applying under high relatively hydraulic pressure, and waterproof effect further promotes.
Description of drawings
Fig. 1 is the utility model embodiment longitudinal sectional view;
Fig. 2 is the utility model embodiment partial sectional view.
The specific embodiment
With reference to figure 1 and Fig. 2, embodiment discloses a kind of waterproof slide fastener, comprise strap 1, strap 2, chain tooth 3, chain tooth 4, pull head 5, TPU 6 and TPU 7, one side of described chain tooth 3 and chain tooth 4 is fixedly arranged on vertical side of strap 1 and strap 2 respectively and extends along its length respectively, the separable engagement setting of the opposite side of described chain tooth 3 and chain tooth 4, the mate that pull head 5 is located at chain tooth 3 and chain tooth 4 slidably is used for unlatching or closes two row's chain tooth engagements, TPU layer 6 and TPU layer 7 are located at the same side of strap 1 and strap 2 respectively and are contacted setting, and two TPU layer contact portion are positioned at chain tooth 3 and chain tooth 4 mates top.And between the strap of each chain tooth and strap coupling part and corresponding TPU, be filled with crosslinking agent such as binary acid, polyalcohol or contain compound such as divinylbenzene, the two isocyanide ester acid etc. of a plurality of unsaturated double-bonds.A vertical side that is positioned at strap simultaneously is provided with the slot to make way (not shown) that chain tooth when closed (pull head moves to the end of slide fastener during closed slide fastener) holds pull head 5, the described two layers of thermoplastic polyurethane resin contact that is positioned on the slot to make way is provided with, by this slot to make way is set, after guaranteeing the slide fastener closure, the position that the TPU layer is positioned at the pull head stop still keeps the watertight effect, thereby realizes the comprehensive waterproof effect of slide fastener.
