Abstract
The invention discloses a high-temperature-resistance zipper. The high-temperature-resistance zipper is formed by combination of copper, high-molecular polymer and high-temperature nylon. The copper is brass and occupies 20-30% of the whole weight of the zipper, the high-molecular polymer occupies 10-15% of the whole weight of the zipper, and the high-temperature nylon occupies 60-65% of the whole weight of the zipper. The high-temperature nylon is poly-adipic acid-hexamethylenediamine formed by condensation polymerization of hexamethylenediamine and adipic acid, and the chemical structural formula of the long-chain molecule of the high-temperature nylon is H-[HN (CH2) XNHCO (CH2) YCO]-OH. The high-temperature-resistance zipper has the advantages of being not prone to be rubbed and high-temperature-resistance.
Description
Technical field
The present invention relates to a kind of high temperature resistant slide fastener, especially design the high temperature resistant slide fastener on a kind of clothes.
Technical background
Background technology
Slide fastener (zipper) slide fastener is to rely on continuously arranged chain tooth, the connector that makes article and close or separate, existing a large amount of clothes, bag, tents etc. of being used for.Slide fastener is made up of chain tooth, pull head, spacing sign indicating number (preceding sign indicating number and back sign indicating number) or locking member etc.Its medium chain tooth is to close the chain link part, and it directly determines the layback intensity of slide fastener.General slide fastener has two chain belts, each has a row chain tooth on the every chain belt, the interlaced arrangement of two row chain teeth.Pull head clamping two side chain teeth by drawing button loop to slide, can make the chain tooth of both sides be meshing with each other or throw off.The detailed content of fastener assembly is: 1, strap tape is used for carrying chain tooth and other fastener assemblies by the flexibility band that cotton yarn, chemical fibre or mixing chemical fibre are made into.2, muscle bead cloth belt edge is used for the reinforcing section of bearing metal or plastic links tooth.3, muscle rope rope refers to be with muscle middle by the fibrous ropy of multiply.4, chain tooth scoops refers to be after metal, plastic or other material are by processing the teeth of definite shape.5, middle heart yearn filler cord is processed by the multiply single, is used for the ropy that nylon zipper tooth chain is produced.6, tooth chain chain refers to continuously arranged tooth.7, tooth chain belt one side zipper chain tooth chain is fixed on and claims the tooth chain belt on the strap.8, chain belt zipper chain forms chain belt by the engagement of both sides tooth chain belt.9, upward end top stop and be fixed on the tooth chain belt, pull head skids off the retainer of tooth chain belt when placing restrictions on the drawing of tooth chain.10, bottom stop is fixed on the tooth chain belt, place restrictions on the tooth chain when drawing back pull head skid off the tooth chain belt, and make that both sides tooth chain belt can not distinct retainer.
Summary of the invention
The invention provides a kind of high temperature resistant slide fastener, have the quilt of being difficult for friction and resistant to elevated temperatures advantage.
Technical scheme of the present invention is: a kind of high temperature resistant slide fastener, described high temperature resistant slide fastener is to be combined by copper, high molecular polymer and high-temperature nylon, described copper is brass, described copper accounts for the 20%-30% of slide fastener overall weight, described high molecular polymer accounts for the 10%-15% of slide fastener overall weight, described high-temperature nylon accounts for the 60%-65% of slide fastener overall weight, described high-temperature nylon be by hexamethylene diamine and adipic acid polycondensation and PA 66, the chemical structural formula of its long-chain molecule is: H-[HN (CH2) XNHCO (CH2) YCO]-OH.
In preferred embodiment of the present invention, described high molecular polymer is polyvinyl chloride.
In preferred embodiment of the present invention, described copper accounts for 22% of slide fastener overall weight, and described high molecular polymer accounts for 14% of slide fastener overall weight, and described high-temperature nylon accounts for 64% of slide fastener overall weight.
The specific embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Wherein, described high molecular polymer is polyvinyl chloride, and polyvinyl chloride is called for short PVC(Polyvinyl chloride polymer=PVC molecular structure), be the thermoplastic resin that under the initator effect, is polymerized by vinyl chloride.It is the homopolymers of vinyl chloride.Ryuron and vinyl chloride copolymer are referred to as vinyl chloride resin.PVC is the white powder of impalpable structure, and the degree of branching is less.Industrial PVC molecular weight generally in 50,000～120,000 scopes, has bigger polydispersity, and molecular weight increases with the reduction of polymerization temperature; No definite melting point, 80～8 5 ℃ begin to soften, and 130 ℃ become the viscoelastic attitude, and 160～180 ℃ begin to change into viscous state; Mechanical performance is preferably arranged, about tensile strength 60MPa, impact strength 5～10kJ/m2; Excellent dielectric properties are arranged.But to the poor stability of light and heat, more than 100 ℃ or through long-time exposure in sunshine, will decompose and produce hydrogen chloride, and further autocatalysis is decomposed, cause variable color, physical and mechanical properties also descends rapidly, must add stabilizing agent in actual applications to improve the stability to light and heat.PVC is very hard, and dissolubility is also very poor, can only be dissolved in the minority solvents such as cyclohexanone, dichloroethanes and oxolane, and all stable to organic and inorganic acid, alkali, salt, chemical stability reduces with the rising of serviceability temperature.PVC is dissolved in acetone-carbon disulfide or the acetone-benzene mixed solvent, is used for dry spinning or wet spinning and forms fiber, claims polyvinyl chloride fibre.Have difficult combustion, acid and alkali-resistance, antimicrobial, wear-resisting and have warmth retention property and elasticity preferably.
Further specify, described high-temperature nylon is commonly called as PPA, has the excellent comprehensive performance, aspect heat, electricity, physics and the chemical resistance good performance is being arranged.Particularly at high temperature still have high rigidity and high strength and splendid dimensional accuracy and stability, this makes HTPA all have application prospect widely in fields such as automobile, electric, mechanical engineerings.HTPA has good processability, can adopt traditional injection machine and mould to carry out processing and forming.HTPA can carry out enhancing on some rerum natura or the change on the color in response to guest's demand, and can provide that glass strengthens, the product of various grades such as fire-retardant.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
