Problems solved by technology

The strong alkali solution will damage the ink layer and the anti-reflection film layer on the film and the glass cover, and has a corrosive effect on metal decorative parts such as aluminum decorative parts. It can only be used for reworking stainless steel colorless decorative parts. For colored metal decorations, strong alkali solution will corrode the color layer on the surface of metal decorations, and will destroy the reliability of metal decorations. Therefore, there has been no effective glue removal for colored metal decorations. Solutions and degumming methods

Abstract

The invention provides an adhesive removing agent and an adhesive removing method, and relates to the field of adhesive removing. The adhesive removing agent comprises, by weight, 8%-25% of phytic acid, 5%-12% of sodium gluconate, 23%-35% of titanium dioxide and 28%-64% of additive. The adhesive removing agent solves the problem that no adhesive removing agent in the prior art can remove adhesiveresidues without damaging a surface structure of a metal decorating part, affecting reliability and appearance and corroding a main material of the metal decorating part, and by the aid of the adhesive removing agent, a panel, appearance and usability of the metal decorating part cannot be affected during adhesive removing.

Description

technical field [0001] The invention relates to the field of degumming, in particular to a degumming agent and a degumming method. Background technique [0002] At present, the cameras and buttons of high-end mainstream mobile phones, tablet computers and other electronic products in the industry are all made of sapphire lenses and metal decorative parts that are bonded at high temperature with thermosetting adhesive or hot melt adhesive. [0003] At present, in electronic products, gradient color cover and glare cover have been well recognized by customers, and have become a fashion, and various colors, patterns and patterns are deeply loved by consumers. There are more and more types of gradient and glare colors. In order to match their gradient and glare characteristics, metal decorative parts of different colors are widely used on various cover panels. However, in the process of dispensing and bonding metal decorative parts with the panel, there will be problems such as...
