Problems solved by technology

[0003] However, magnesium is very active and has a low ignition point. General glue removers cannot be used to remove glue from magnesium materials.
In addition, traditional glue removers generally use highly toxic solvents such as toluene and methylene chloride, which have high volatility, high chemical oxygen demand (COD), high toxicity, serious environmental pollution, and great harm to the human body of operators

Abstract

The invention discloses a water-based adhesive remover. The water-based adhesive remover comprises strong alkali, a main solvent, a volatilization inhibitor, a cosolvent, a corrosion inhibitor, a penetrating agent, a thickening agent, a surfactant and water. The water-based adhesive remover is a water-based formula, and the water-based formula is not prone to volatilizing or burning; when the water-based adhesive remover is used for removing the adhesive on the surface of a magnesium material, it can be guaranteed that the magnesium material cannot be burnt, the safety is high, and a magnesiumalloy substrate cannot be corroded. The water-based adhesive remover can be used by heating, thus curing adhesives which are difficult to remove can be quickly removed, and the adhesive removing efficiency is high. The water-based adhesive remover further has good degradability and little harm to the environment. The water-based adhesive remover does not contain chlorine or benzene, has low toxicity and is environmentally friendly and healthy. The water-based adhesive remover does not contain specific fluorine-chlorine carbohydrates, ethane or other harmful substances which damage the ozone layer, and has a low chemical oxygen demand. The surface of the magnesium material treated by the water-based adhesive remover does not contain grease residues and can be directly washed with water.

Description

technical field [0001] The invention relates to a glue remover, in particular to a water-based glue remover. Background technique [0002] At present, magnesium alloy is used in the components of electronic products. For example, the material of the notebook case is a combination of magnesium alloy and glass fiber plastic. During manufacture, the two materials of magnesium alloy and glass fiber plastic need to be bonded together with an adhesive (for example, AB glue). If there are defective products in the production process, in order to save costs, the defective products will generally be repaired, and glue removers need to be used to remove the adhesive and recycle the magnesium material. [0003] However, magnesium is very active and has a low ignition point, so general glue removers cannot be used to remove glue from magnesium materials. In addition, traditional glue removers generally use highly toxic solvents such as toluene and methylene chloride, which have high v...
