Abstract

The invention relates to the technical field of stirring agents, in particular to a metal stripping agent and a preparation method thereof. The metal stripping agent is prepared from 6-ethyl-o-toluidine, tetrabutyl titanate, water, dibutyltin dilaurate, polyethylene wax and stearamide, wherein the 6-ethyl-o-toluidine is subjected to the grafting reaction, a reaction product is then mixed with the residual 6-ethyl-o-toluidine, the polyethylene wax and the stearamide, and thus the metal stripping agent is prepared. A reaction product obtained through coupling of the dibutyltin dilaurate and the 6-ethyl-o-toluidine is combined with the residual 6-ethyl-o-toluidine, a good stripping effect on protection glue on a metal surface is achieved, and the advantages that the stripping time is short and combustion is unlikely to occur are achieved. The preparation method of the metal stripping agent has the characteristics of being simple, low in production cost and suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of stripping agents, in particular to a metal stripping agent and a preparation method thereof. Background technique [0002] At present, the protective glue used for metal protection is generally difficult to remove. This is mainly because strong acids and strong alkalis cannot be used to peel off metal protective glues, because strong acids and strong alkalis are corrosive to metals. For example, in the touch screen industry, in the process of manufacturing the touch screen, it is necessary to use peeling glue to peel off the protective glue on the metal surface of the touch screen. [0003] In the prior art, although there have been metal strippers with a neutral pH, for example, a mixture of monoethanolamine and diethylene glycol monobutyl ether is used as a metal stripper, but the protection of metal surfaces by this type of metal stripper The stripping effect of the glue is not good, and the stripping...
