Abstract

The invention relates to a cleaning agent and its preparation method and application, belonging to the field of resources and environmental waste treatment. The feature of the present invention is to select surfactants with penetration, foaming and emulsification: sodium dodecylsulfonate, fatty alcohol polyoxyethylene ether sodium sulfate, and acid-base agents with the effect of regulating pH: sodium hydroxide, hydrogen Potassium oxide and barium hydroxide, humectants with the function of maintaining humidity: ethylene glycol, propylene glycol, and solvents with dissolution function: isopropanol, ethanol, propylene glycol methyl ether, etc. are mixed in sequence. The present invention has the following advantages: the cleaning agent is sprayed onto the solid matter, penetrated and dissolved for 5-10 minutes, and then applied with a rag, which can quickly and conveniently remove advertising stickers, ink marks, pressure-sensitive adhesive marks and marker handwriting on the surface .

Description

technical field [0001] The invention relates to a cleaning agent and its preparation method and application, belonging to the field of resources and environmental waste treatment. Background technique [0002] Pressure-sensitive adhesive, commonly known as self-adhesive, is widely used in all aspects of life because of its strong binding force, convenience and quickness (the area of ​​adhesive tape produced in my country has reached 40×10 8 m 2 , and 20~30% of them belong to pressure-sensitive adhesive stickers). At present, in order to improve the quality of tapes, merchants are working hard in the direction of enhancing the bonding force and water resistance of tapes. [0003] However, it is precisely because of the strong adhesion and high water resistance of the pressure-sensitive adhesive that it is difficult to clean up the waste small advertisements such as certificates and diplomas (often called urban psoriasis) posted everywhere on urban buildings. The means of ...
