Zipper with double open ends

Abstract

The invention discloses a zipper with double open ends. Protective paint is coated on the surfaces of metal teeth of the zipper. A method for preparing the protective paint includes steps of 1), sequentially feeding, by weight, 1-2 parts of tri (cetyl alcohol) ester, 1.6 parts of fatty alcohol polyoxyethylene ether, 2.3 parts of dibutyl succinate, 0.7 part of sodium polyacrylate and 16 parts of castor oil alkyd resin into 25 parts of deionized water and uniformly stirring the tri (cetyl alcohol) ester, the fatty alcohol polyoxyethylene ether, the dibutyl succinate, the sodium polyacrylate, the castor oil alkyd resin and the deionized water to obtain mixtures; 2), sequentially feeding, by weight, 0.5 part of zinc borate, 2.7 parts of isopropyl alcohol, 0.7 part of methyl-1H-benzotriazole, 2.2 parts of succinic acid and 0.7 part of fatty alcohol ether sodium sulfate into the mixtures and continuing to stir the zinc borate, the isopropyl alcohol, the methyl-1H-benzotriazole, the succinic acid, the fatty alcohol ether sodium sulfate and the mixtures until the zinc borate, the isopropyl alcohol, the methyl-1H-benzotriazole, the succinic acid, the fatty alcohol ether sodium sulfate and the mixtures are sufficiently uniformly mixed with one another to obtain the protective paint. The zipper with the double open ends has the advantages that the protective paint is coated on the surfaces of the teeth of the zipper, and accordingly the zipper can be assuredly used for a long term.

Description

technical field [0001] The invention relates to a double-end zipper. Background technique [0002] In the existing zipper, the wear resistance, oxidation resistance, rust resistance and corrosion resistance of the metal chain elements need to be improved, which affects the long-term use of the zipper. Contents of the invention [0003] The purpose of the present invention is to provide a double-open end zipper, the metal chain elements are coated with protective paint, so that the metal chain elements have excellent wear resistance, oxidation resistance, rust resistance and corrosion resistance, thereby ensuring the long-term use of the zipper. [0004] In order to achieve the above object, the technical solution of the present invention is to design a double-open end zipper, including a chain belt, the chain belt longitudinal edge is provided with chain teeth, and the surface of the metal chain teeth is coated with protective paint, and the protective paint is passed thro...
