[0023] A normal temperature glue cleaning agent is made up of the following substances by weight percentage: dichloromethane, ethylene glycol monobutyl ether, methyl alcohol, No. 120 solvent naphtha, benzotriazole, paraffin and sodium dodecylbenzenesulfonate, Table 1 is as follows by weight percentage.
[0024] The preparation method of normal temperature glue cleaning agent is as follows: put methanol, part of dichloromethane, No. 120 solvent oil, benzotriazole, and sodium dodecylbenzenesulfonate in a container and stir to dissolve, as component A, heat the paraffin Melt, add another part of dichloromethane, add ethylene glycol monobutyl ether as component B under heating and reflux, add component A, stir evenly to obtain the finished product.

The invention discloses a normal-temperature glue detergent and a preparation method thereof. The normal-temperature glue detergent disclosed by the invention is prepared from the following ingredients in percentage by weight: 65% to 75% of dichloromethane, 12.5% to 20.0% of ethylene glycol monobutyl ether, 6.5% to 10.5% of methanol, 2.5% to 5.5% of 120# solvent oil, 0.25% to 0.45% of benzotriazole, 0.75% to 1.5% of paraffin and 0.15% to 0.35% of sodium dodecylbenzene sulfonate. According to the normal-temperature glue detergent and the preparation method thereof, the dichloromethane serves asa primary solvent, the ethylene glycol monobutyl ether, the methanol and the 120# solvent oil serve as cosolvents, the sodium dodecylbenzene sulfonate serves as an anionic surfactant, and the paraffin serves as a penetrant; after the normal-temperature glue detergent is sprayed onto the surface of a glue film, the primary solvent and the other cosolvents rapidly dissolve part of the glue film onthe surface of the film, paraffin liquid rapidly penetrates into the film and is rapidly cured after solvent volatilization, the glue film is isolated from the original surface, and thus, the originalglue film is very easy to peel off.
Description
technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a normal-temperature glue cleaning agent and a preparation method thereof. Background technique [0002] The glue cleaning methods currently used in the market (mainly 502 glue) are as follows: [0003] 1. Scrape off with a hard object, such as a sharp blade. The disadvantage is that the complex surface or inner surface is difficult to scrape off, and there will be marks on the surface, which will damage the surface. [0004] 2. Dissolve the glue with a hot solvent (such as hot water). The disadvantage is also that it is difficult to remove the glue on the complex surface or inner surface, and it cannot be implemented in places without heating conditions. [0005] 3. Dissolve in strong solvents such as xylene and acetone. The disadvantage is that the solvent has a large environmental burden, and if the glue is not removed in time after it dissolves, the ...
