Technical field
The present invention relates to waterproof slide fastener, wherein pull head is inserted through a pair of tooth chain, each tooth chain is provided with by a plurality of slide fastener made of synthetic resin elements (fastener element) on each the element mounting edge part that is integrally formed at the waterproof slide fastener band, and the waterproof slide fastener band applies the banded core of weaving or braiding by watertight composition and makes.
Background technology
This waterproof slide fastener has a pair of left and right zipper strip.Each zipper strip comprise with the band main body of silvalin weaving or braiding or with banded adhesive-bonded fabric as its core, the forward and backward face of core is coated with the watertight composition of elastomer formation.The mutual relative side edge portions of a pair of zipper strip is as element mounting edge part, in forward and backward mode striding across zipper strip by injection moulding along the plastic slide fastener elements of element mounting edge part monolithic molding, in addition, the pull head that is used to engage or throws off left and right slide fastener elements is inserted through the slide fastener elements row of tooth chain.
Generally, in waterproof slide fastener, the through hole that penetrates forward and backward of zipper strip is formed on the shaped portion of each slide fastener elements in advance on the element mounting edge part of zipper strip.When synthetic resin is formed in the shaped portion of each slide fastener elements with through hole by injection moulding, as the passage of synthetic resin slide fastener elements is formed on forward and backward of zipper strip symmetrically with through hole, makes slide fastener elements partly be clipped in the middle the element mounting edge.In addition, each slide fastener elements forms and makes and connect into integral body in slide fastener elements the latter half of slide fastener elements the first half of zipper strip front face side and side in the back coupling part by penetrated through via holes, thereby has strengthened the bonding strength between zipper strip and the slide fastener elements.
The embodiment of existing waterproof slide fastener is disclosed in open No.63-30247 of Japanese Utility Model and the open No.2005-237577 of Japan Patent.
For example, in the open described waterproof slide fastener of No.63-30247 of Japanese Utility Model, watertight composition is located on forward and backward of zipper strip, and through hole is located at the element mounting edge part of zipper strip.The upper and lower half branch of slide fastener elements is formed on forward and backward of element mounting edge part, and the upper and lower half of slide fastener elements divides the coupling part by passing the through hole in the element mounting edge part to form integral body.In addition, in the waterproof slide fastener of the open No.63-30247 of Japanese Utility Model, adhesive layer be formed on corresponding forward and backward of the periphery of the through hole at least of zipper strip on.Zipper strip and bonded dose of layer of the contacted boundary member of slide fastener elements around the through hole seal, thereby keep the watertightness of boundary member.
In addition, the open No.2005-237577 of Japan Patent discloses the waterproof slide fastener that has characteristics at the vpg connection of slide fastener elements.In the open No.2005-237577 of Japan Patent in one type of disclosed waterproof slide fastener, each slide fastener elements comprises connection head, neck, main part and shank, each slide fastener elements comprises the last the latter half on forward and backward that is integrally formed at zipper strip, and shank extends to the inside of zipper strip from main part.These half parts are whole the connection by the coupling part of passing the through hole in the slide fastener elements mounting portion.In each slide fastener elements, half and half part of connection head and shank is set as along half and half part of forward and backward direction ratio neck of vertical zipper strip and main part thinner.In addition, the flanging up and down of sliding guidance pull head is divided in the upper and lower half of shank, and two or more half parts are located at the glide direction of pull head with predetermined spacing.
In the waterproof slide fastener of the open No.2005-237577 of Japan Patent, the slide fastener elements that wherein has this shape is located on the element mounting edge part, therefore the two or more upper and lower half branch that is used for the shank by sliding motion guiding pull head has reduced the feasible slide pull head swimmingly of resistance to sliding along the glide direction setting when pull head slides.In addition, when carrying out the injection moulding of slide fastener elements, pressurize by the forward and backward zipper strip of facing of the profile between the half part die cavity of shank from zipper strip.Therefore, when being shaped, in zipper strip, do not produce swing, make and each shank is effectively made integral body with the forward and backward face of zipper strip by fusing.Therefore, has the advantage that the increase slide fastener elements is fixed in the constant intensity of zipper strip.
According to open No.63-30247 of Japanese Utility Model and the open No.2005-237577 of Japan Patent, the zipper strip of waterproof slide fastener uses shoestring with silvalin weaving or braiding as core, the forward and backward face of banded core is coated with watertight composition, and comprises that the elastomer of natural rubber, synthetic rubber or analog is used as watertight composition.But, the open No.2005-237577 of open No.63-30247 of Japanese Utility Model and Japan Patent generally openly can be used as the material of watertight composition, in the market most of waterproof slide fasteners of Xiao Shouing generally comprise as watertight composition, at good thermoplastic polyester elastomers (particularly Hytrel (registration mark)) in aspect such as intensity, durability, forming technologies.Having has the polybutylene terephthalate (PBT) of fabulous viscosity and intensity as the material that is formed on the slide fastener elements on the zipper strip to Hytrel (registration mark).
On the other hand, the use of waterproof slide fastener is in recent years expanded, and the object that waterproof slide fastener will connect also changes thereupon, therefore requires to improve waterproof slide fastener and the viscosity that is connected object.But though it is good to be used to cover the intensity and the forming technology of thermoplastic polyester elastomer of zipper strip, this elastomer is very poor with the viscosity that is connected object that comprises polyurethane matrix.For this reason, the zipper strip with the watertight composition that comprises thermoplastic polyester elastomer can not be bonded on polyurethane matrix material or the polyurethane-coated material easily.Particularly, when attempt is connected to the waterproof slide fastener of the watertight composition that is formed by polyester elastomer on the connection object that comprises polyurethane matrix, can not use the high frequency fusing of common usefulness, and need sewing or binding agent, this will spend more work time and labour.
In addition, polyester elastomer is poor as its plasticity of elastomer.Therefore, the zipper strip tendency that is coated with polyester elastomer is harder, and therefore, when when its forward and backward face curves U-shaped or when reversing, flexibility is lower.Therefore, when the waterproof slide fastener that is formed by polyester elastomer when watertight composition wherein is connected to as the connection object of diving suit and so on, the coupling part hardening of waterproof slide fastener.As a result, the user feels to be difficult to wear or to take off this connection object, and wearing comfortableness is just relatively poor when the user wears.
Simultaneously, in order to improve the viscosity that is connected object with polyurethane matrix, consider to use polyurethane elastomer, this elastomer is than the easier connection object that is bonded to polyurethane matrix of polyester elastomer, and the watertight composition that conduct is formed on the zipper strip is that plasticity is more arranged.Yet,, reduce greatly with the viscosity of the slide fastener elements of polybutylene terephthalate (PBT) if the watertight composition of zipper strip is only formed by polyurethane elastomer.
Therefore, even by by the coupling part that is passed in the through hole in the element mounting edge part top and the bottom integrally being coupled together each slide fastener elements is formed on the zipper strip, the constant intensity between zipper strip and slide fastener elements also must reduce.This may reduce the bond strength and the watertightness of waterproof slide fastener.In addition, slide fastener elements can rotate around the coupling part, and therefore left and right slide fastener elements row can not be bonded with each other suitably.
Summary of the invention
Therefore, the present invention finishes in order to address the above problem, the purpose of this invention is to provide a kind of waterproof slide fastener, wherein zipper strip with as to be coated with the viscosity that is connected object of urethane coating good, have good bendability, have high constant intensity between zipper strip and slide fastener elements, this waterproof slide fastener also has good bond strength and watertightness.
For realizing above-mentioned purpose of the present invention, waterproof slide fastener of the present invention is a kind of waterproof slide fastener that waterproof construction is arranged, it is characterized in that comprising: a pair of tooth chain, wherein by along the relative element mounting edge part monolithic molding of a pair of waterproof slide fastener band and a plurality of slide fastener elements in a row are set, in described zipper strip, comprise that the banded core of yarn fabric, braid or adhesive-bonded fabric is coated with watertight composition; With a pull head that is used to engage and throw off slide fastener elements; Wherein said watertight composition comprises polyurethane elastomer, described slide fastener elements comprises the polymeric blends of polyurethane resin and ABS resin, in polymeric blends, the weight ratio of polyurethane resin and ABS resin (polyurethane resin/ABS resin) is 20/80 to 50/50.
In the zipper strip of waterproof slide fastener of the present invention, banded core is coated with the watertight composition that comprises polyurethane elastomer, is connected and is formed on the zipper strip with the slide fastener elements of the polymeric blends of a plurality of poly-amino ester resins and ABS resin is whole.
The present inventor has considered to use polyurethane elastomer to replace existing polyester elastomer (for example Hytrel) commonly used as watertight composition, has watertight composition and covers zipper strip on it and adhere to viscosity as the connection object that is coated with urethane coating so that strengthen.But,, then reduce with the viscosity of polybutylene terephthalate (PBT) slide fastener elements as mentioned above if watertight composition is formed by polyurethane elastomer.Then, the inventor has accumulated test and has considered, use with the polyurethane elastomer compatibility good, show have the new synthetic resin of good viscosity to replace existing polybutylene terephthalate (PBT).
At first, the inventor considers with the compatibility of the polyurethane elastomer of watertight composition and viscosity and uses the material of polyurethane resin as slide fastener elements separately.But if slide fastener elements is only formed by polyurethane resin, though improved with the viscosity of polyurethane elastomer, when slide fastener elements was shaped, resin cooling and sclerosis needed the long time, so cast gate is difficult to cut away, thereby formability is poor.In addition, clearly, the slide fastener elements that polyurethane forms lacks practicality, because this slide fastener elements is very soft and lack rigidity as slide fastener elements.Can consider to use ABS resin or polycarbonate resin and polyurethane as the slide fastener elements material.But,, be difficult to obtain the intensity of slide fastener elements, and the chemical proof of element is poor if use in above-mentioned these resin materials any separately.
Then, use the above-mentioned shortcoming of polyurethane resin, done further test and consideration about material as the slide fastener elements material for solving.The result, the discovery ABS resin has with polyurethane resin good compatibility and good formability is arranged, so the polymeric blends that uses polyurethane resin and ABS resin has obviously improved the formability of slide fastener elements as the material of slide fastener elements and has strengthened the rigidity of slide fastener elements, has therefore finished the present invention.
That is to say that the watertight composition that will be formed on the zipper strip is to be made by polyurethane elastomer, and the slide fastener elements that is integrally formed on the zipper strip is the waterproof slide fastener that comprises the polymeric blends of polyurethane resin and ABS resin, can produce the performance of corresponding material.Therefore, zipper strip have with as be coated with urethane coating be connected good viscosity of adhering object and fabulous wear resistence.In addition, the formability and the rigidity of slide fastener elements are good, and the constant intensity between zipper strip and the slide fastener elements increases.
Therefore, waterproof slide fastener of the present invention and polyurethane-base be plastic, and to be connected the viscosity of object good, because this slide fastener is shaped easily and the surface coverage of zipper strip has polyurethane elastomer.Therefore, waterproof slide fastener is preferably used for comprising the connection object of polyurethane matrix.The watertightness of the flexibility of waterproof slide fastener of the present invention, wearability, bond strength and zipper strip is fine.
In addition, the inventor also considers the function of the ratio of polyurethane resin and ABS resin in the polymeric blends that constitutes slide fastener elements with the improvement waterproof slide fastener.As a result, when the weight ratio (polyurethane resin/ABS resin) of polyurethane resin and ABS resin in the waterproof slide fastener of the present invention was 20/80 to 50/50, formability, the strength and stiffness of slide fastener elements further improved.Therefore, the horizontal stretching resistance of waterproof slide fastener of the present invention etc. are fine, thereby guaranteed high-quality.Effect of the present invention is quite big.

The waterproof slide fastener 1 of present embodiment comprises tooth chain 2, synthetic resin or metal pull head (not shown), preceding sign indicating number (not shown) and the back sign indicating number (not shown) that separates.In tooth chain 22, along the element mounting edge part 11 of the side edge portions of the zipper strip 10 that is arranged on water resistance, a plurality of slide fastener elements 21 are with interlock spacing and slide fastener elements 21 monolithic moldings that respectively are complementary.The pull head (not shown) engages with left and right sides slide fastener elements 21 and/or throws off.
In zipper strip 10, the whole front-back of the banded core of being made by silvalin yarn fabric, braid or adhesive-bonded fabric 12 is covered by the watertight composition 13 of elastic polyurethane system.Because zipper strip 10 is covered by polyurethane elastomer, so, water resistance can be guaranteed, and zipper strip can melt with high frequency easily and be connected on polyurethane-base system or the connection object coated with urethane coating.In addition, zipper strip itself becomes that the zipper strip of polyester elastomer has more flexibility than for example being coated with, thereby the bending property that can obtain.Each element shaped portion in the element mounting edge part 11 of zipper strip 10 is provided with through hole 14, and this through hole passes through wherein to the raw material resin of the slide fastener elements 21 that enough makes molten state greatly.
Above-mentioned slide fastener elements 21 includes oval-shaped connection head 22, is branched off into two parts ground shank 27 of extension downwards by neck 23 hexagonal substantially main part 24 continuous with being connected head 22, the wing shoulder 25 that extends at left and right sides with from the lower end of main part 24 via forked section 26 between neck 23 and main part 24.Slide fastener elements 21 with this structure has last the latter half of the element mounting edge part 11 of passing zipper strip 10, and the latter half integrally couples together mutually by the coupling part 28 that forms in through hole 14 on these.
Separately half part 22a, the 22b that connect head 22, neck 23, main part 24, shoulder 25 and shank 27; 23a, 23b; 24a, 24b; 25a, 25b; 27a, 27b are integrally formed at passing on forward and backward of zipper strip 10 of zipper strip 10 with the shape of symmetry.Here, half and half part 23a, the 23b except that connecting head 22; 24a, 24b; 25a, 25b and 27a, 27b make one by the fusing and the forward and backward face of zipper strip 10.
Be formed in half part 22a, the 22b of the connection head 22 of the upper and lower that passes zipper strip 10 symmetrically, under the state outside the ora terminalis 11a of the element mounting edge part 11 of zipper strip 10 is exposed to a little, extend in the outside of ora terminalis 11a abreast.The ora terminalis 11a of element mounting edge part 11 is set following size from shoulder 25 extended length of exposure L1, promptly, when connect head 22 with mate be connected head 22 interlocks the time, the exposed end face of ora terminalis 11a contacts with the mutual pressure of the exposed end face of the zipper strip that is complementary 10.Therefore, in connection status, therefore the mutual pressure contact of the opposing end surface of zipper strip 10 produces water resistance.
On the other hand, separately half part 23a, the 23b of neck 23, main part 24, shoulder 25 and shank 27; 24a, 24b; 25a, 25b and 27a, 27b are fixed firmly to the element mounting edge part 11 of zipper strip 10.Wherein, separately half part 23a, the 23b of neck 23 and main part 24 and the thickness maximum of 24a, 24b, and separately half part 25a, the 25b of shoulder 25 and shank 27 and 27a, 27b be set to separately half part 23a, the 23b of neck 23 and main part 24 and 24a, 24b thickness about 1/3rd.
The outer surface of half part 22a, 22b outer surface and the neck 23 of connection head 22 and separately half part 23a, the 23b of main part 24 and 24a, 24b is in the same plane.Because this structure, when the mutual interlock of slide fastener elements 21, as shown in figs. 1 and 3, half part 25a, the 25b of each shoulder 25 of the slide fastener elements 21 adjacent with left and right sides contacts with the inner face of the half part 22a, the 22b that are connected head 22 of the slide fastener elements 21 of a side.
In the waterproof slide fastener 1 of present embodiment, the slide fastener elements 21 with said structure is made by the polymeric blends of polyurethane resin and ABS resin.Because polyurethane resin is composited, so the slide fastener elements of being made by this polymeric blends 21 can strengthen the intensity on the zipper strip 10 that is fixed to the watertight composition 13 that has wherein formed polyurethane elastomer.In addition, because ABS resin also is composited, so, can improve the formability and the rigidity of slide fastener elements 21.Simultaneously, the polyurethane resin that is used in the polymeric blends is a thermoplastic resin, and this resin is different with the polyurethane elastomer of the watertight composition 13 that forms in zipper strip 10, but harder and be not so good as this elastomer and can easily stretch like that than this elastomer.
Especially, slide fastener elements 21 is constructed such that the weight ratio (polyurethane resin/ABS resin) of polyurethane resin and ABS resin is 20/80 to 50/50 in polymeric blends.If the weight ratio of polyurethane resin less than 20%, then can not be fixed the enough intensity in zipper strip, and slide fastener elements 21 ftractures easily owing to lack intensity.As a result, the bond strength of slide fastener 1 reduces.On the other hand, if the weight ratio of ABS resin less than 50%, then the formability of slide fastener elements 21 and rigidity become not enough, thereby may cause the bond strength of slide fastener 1 to reduce.
Then, polyurethane resin chip and ABS resin chip mix with predetermined weight and melt.Molten resin material imports die cavity by sprue, cross gate and cast gate.The resin of the fusing of importing die cavity is passed in the through hole 14 in the zipper strip 10, then, the front-back that is formed on element mounting edge part 11 is symmetrically divided in the upper and lower half of slide fastener elements 21, and the upper and lower half divides the coupling part 28 by formation in through hole 14 to couple together and shaping integrally.The result obtains the waterproof slide fastener 1 of the present embodiment shown in Fig. 1 to 3.
In the waterproof slide fastener 1 of the present embodiment with said structure, zipper strip 10 has and is adhered to admirably as the viscosity of the connection object that scribbles urethane coating and good wear resistence, and the formability of slide fastener elements and rigidity are good.In addition, the constant intensity between zipper strip and the slide fastener elements is very high.This waterproof slide fastener is easy to be shaped, and the flexibility of zipper strip, bond strength and watertightness are fine.
