Color change-preventing and wear-resistant protective agent of automotive interior metal zipper

Abstract

The invention discloses a color change-preventing and wear-resistant protective agent of an automotive interior metal zipper. The color change-preventing and wear-resistant protective agent is prepared from the following components in parts by weight: 30 to 50 parts of resin, 0.3 to 1 part of surface modified nano SiO2, 0.1 to 5 parts of surfactant, 0.1 to 0.5 part of film forming matter, 1 to 35 parts of solvents, 5 to 8 parts of silane coupling agent and deionized water as the rest. According to the color change-preventing and wear-resistant protective agent, the zipper is soaked in a protective agent solution, or the protective agent is sprayed to the surface of the zipper, so as to form a uniform dense bright protective layer, so that the metal zipper is prevented from discoloring and fading, and the color overlapping of the metal zipper to fabrics is reduced, so as not to influence the product quality. The color change-preventing and wear-resistant protective agent is favorable for environmental protection and has the advantages of simplicity in arrangement, low treatment cost and convenience when the color change-preventing and wear-resistant protective agent is used for protecting the surface of the zipper.

Description

technical field [0001] The invention relates to the anti-oxidation, anti-discoloration and wear-resisting treatment of metal zippers in automobile interiors, in particular to a treatment agent for forming a protective film with a nanometer thickness on the surface of the metal zippers. Background technique [0002] At present, when inspecting finished metal zippers for automotive interiors, it is usually found that dark metal zippers are more likely to contaminate fabrics. Dark zippers are made of brass zippers that are chemically colored. This coloring layer tends to stain fabrics, especially for light-colored fabrics. This chemical coloring process is different from the electroplating process. The pores are larger, the adhesion fastness is relatively poor, and color transfer is prone to occur after contact, friction, and enzyme washing. At the same time, when the zipper encounters acidic or alkaline additives during the printing and dyeing process, it is easy to cause the...

The coloring layer is easy to stain the fabric, especially for light-colored fabrics

This chemical coloring process is different from the electroplating process, the pores are larger, the adhesion fastness is relatively poor, and color transfer is prone to occur after contact, friction, and enzyme washing

At the same time, when the zipper encounters acidic or alkaline additives during the printing and dyeing process, it is easy to cause the surface of the metal to be oxidized and cause the zipper to change color.
