Abstract

The invention discloses a scavenging agent for scavenging chewing gum residual and a preparation method thereof. The scavenging agent for scavenging the chewing gum residual consists of carbon disulfide, methylene dichloride, ethyl acetate, span-80, cyclohexanone, sodium dodecyl benzene sulfonate and water. The preparation method comprises the following steps: mixing the carbon disulfide and the water, simultaneously adding the methylene dichloride and the ethyl acetate, mixing and heating 50 to 60DEG C; and adding the sodium dodecyl benzene sulfonate, stirring to completely dissolve solid, adding the cyclohexanone and then the span-80, stirring to obtain a reaction product, and cooling to room temperature to obtain the scavenging agent for scavenging the chewing gum residual. The scavenging agent for scavenging the chewing gum residual can easily erase the chewing gum residual (vestiges) on floors, marble floors, rails, and walls, and has stable performance, low cost, no toxin or harm, and no pollution to environment.

Description

technical field [0001] The invention relates to a scavenger for removing chewing gum residues and a preparation method thereof. Background technique [0002] At present, there are two main types of chewing gum removers: one is a mixed solvent of enzymes and ionic liquids jointly developed by researchers from the University of Manchester and Queen's University Belfast, which can decompose and dissolve gums on the street and on the sidewalk. Hardened gum stains. But this scavenger research investment is as high as 1 million pounds, and the cost is extremely high. The other is that Qingdao Jiajiale Cleaning Products Co., Ltd. proudly launched glue remover (gel sol, chewing gum stain cleaner), which is used to remove chewing gum garbage with special effects and remove residual stains such as stickers, carpet glue, wallpaper glue, floor glue, etc. But this scavenger is serious to environmental pollution, and the gas that volatilizes is harmful to human body. Contents of the i...
